Technical Field

The present disclosure relates to an article of footwear, and more particularly, to an article of footwear and a sole structure having sensory node elements located at discrete locations.

Background

Conventional articles of athletic footwear include two primary elements: an upper and a sole structure. The upper provides a covering for the foot that comfortably receives the foot and securely positions the foot with respect to the sole structure. The sole structure is secured to a lower portion of the upper and is positioned generally between the foot and the ground. In addition to attenuating ground reaction forces (i.e., providing cushioning) during walking, running, and other ambulatory activities, the sole structure may, for example, affect foot motions (e.g., by resisting pronation), impart stability, and provide traction. Accordingly, the upper and the sole structure operate cooperatively to provide a comfortable structure that is suited for a variety of athletic activities.

The upper is generally formed from a plurality of material elements (e.g., textiles, polymer sheets, foam layers, leather, and synthetic leather) that are stitched or adhesively bonded together to define a void or cavity on the interior of the footwear for comfortably and securely receiving a foot. More specifically, the upper forms a structure that extends over instep and toe areas of the foot, along medial and lateral sides of the foot, and around a heel area of the foot. The upper may also incorporate a lacing system to adjust the fit of the footwear and to allow the foot to enter and exit the void within the upper. In addition, the upper may include a tongue that extends under the lacing system to enhance adjustability and comfort of the footwear, and the upper may incorporate a heel counter or other stabilizing structure.

In some instances, the cushioning provided by the sole structure may undesirably reduce sensory feedback by isolating the foot of the wearer from ground contact while attenuating ground reaction forces. Accordingly, there is a need in the art for a sole structure that includes provisions for increasing sensory feedback to a wearer's foot.

SUMMARY

In one aspect, the present invention provides a sole structure for an article of footwear. The sole structure includes a sole body portion. The sole body portion includes an outsole surface that faces away from the article of footwear and an upper surface disposed opposite the outsole surface. The sole structure also includes a plurality of sensory node elements disposed within apertures in the sole body portion. The apertures may be located in at least portions of the forefoot region, midfoot region, and heel region of the sole structure. Each of the plurality of sense node elements includes a bottom surface configured to engage the ground plane and a top surface disposed opposite the bottom surface. The bottom surface of each of the sensory node elements extends above the outsole surface of the sole body portion when the sensory node elements are in an uncompressed state. Each of the plurality of sensory node elements is configured to move vertically within an aperture in the body portion of the sole such that when the sensory node element is in a stressed state, a bottom surface of the sensory node element moves in a direction closer to an outer sole surface of the body portion of the sole.

In another aspect, the invention provides an article of footwear. An article of footwear includes an upper and a sole structure coupled to the upper. The sole structure includes a sole body portion. The sole body portion includes an outsole surface that faces away from the article of footwear and an upper surface disposed opposite the outsole surface. The sole structure also includes a plurality of sensory node elements disposed within apertures in the sole body portion. The apertures may be located in at least portions of the forefoot region, midfoot region, and heel region of the sole structure. Each of the plurality of sense node elements includes a bottom surface configured to engage the ground plane and a top surface disposed opposite the bottom surface. The bottom surface of each of the sensory node elements extends above the outsole surface of the sole body portion when the sensory node elements are in an uncompressed state. When the sensory node elements are in a stressed state, a top surface of each of the sensory node elements extends toward an interior of the upper above an upper surface of the sole body portion.

Other systems, methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description.

Detailed Description

The following discussion and accompanying figures disclose an article of footwear and a sole structure for an article of footwear. Concepts associated with the articles of footwear disclosed herein may be applied to a variety of athletic footwear types, including for example, skate shoes, performance driving shoes, soccer shoes, running shoes, baseball shoes, basketball shoes, cross-training shoes, cycling shoes, football shoes, golf shoes, tennis shoes, walking shoes, and hiking boots. The concept may also be applied to footwear styles that are generally considered to be non-athletic, including dress shoes, loafers, sandals, and work boots. Accordingly, the concepts disclosed herein apply to a wide variety of footwear types.

For consistency and convenience, directional adjectives are used throughout this detailed description corresponding to the illustrated embodiments. The term "longitudinal" as used throughout this detailed description and in the claims refers to a direction extending a length of a sole structure, i.e., a direction extending from a forefoot region to a heel region of the sole structure. The term "forward" is used to refer to the general direction in which the toe of the foot points, and the term "rearward" is used to refer to the opposite direction, i.e., the direction in which the heel of the foot faces.

The term "lateral direction" as used throughout this detailed description and in the claims refers to a side-to-side direction (side-to-side direction) that extends the width of the sole structure. In other words, the lateral direction may extend between a medial side and a lateral side of the article of footwear, where the lateral side of the article of footwear is the surface that faces away from the other foot and the medial side is the surface that faces toward the other foot.

The term "horizontal" as used throughout this detailed description and in the claims refers to any direction generally parallel to the ground, including longitudinal, lateral, and all directions in between. Similarly, the term "side" as used in this specification and in the claims refers to any portion of a component that generally faces in an outboard, inboard, forward, and/or rearward direction (as opposed to an upward or downward direction).

The term "vertical" as used throughout this detailed description and in the claims refers to a direction that is substantially perpendicular to both the transverse and longitudinal directions. For example, where the sole structure is flat resting on the ground, the vertical direction may extend upward from the ground. It should be understood that each of these directional adjectives may apply to the article of footwear, the sole structure, and individual components of the sole structure. The term "upward" refers to a vertical direction proceeding away from the ground, while the term "downward" refers to a vertical direction proceeding toward the ground. Similarly, the terms "top," "upper," and other similar terms refer to the portion of an object that is generally furthest from the ground in a vertical direction, while the terms "bottom," "lower," and other similar terms refer to the portion of an object that is generally closest to the ground in a vertical direction.

For purposes of this disclosure, the above directional terms, as used with respect to an article of footwear, shall refer to the article of footwear when in an upright position, with the sole facing the ground, that is, as the article of footwear would be positioned when worn by a wearer standing on a generally horizontal surface.

Fig. 1-10 illustrate an exemplary embodiment of an article of footwear 100 (also referred to simply as article 100). In some embodiments, article of footwear 100 may include sole structure 110 and upper 120. For reference purposes, article 100 may be divided into three general regions: forefoot region 10, midfoot region 12, and heel region 14, as shown in fig. 1-6. Forefoot region 10 generally includes portions of article 100 corresponding with the toes and the joints connecting the metatarsals with the phalanges. Midfoot region 12 generally includes portions of article 100 corresponding with an arch area of the foot. Heel region 14 generally corresponds with rear portions of the foot, including the calcaneus bone. Article 100 also includes a lateral side 16 and a medial side 18, with lateral side 16 and medial side 18 extending through each of forefoot region 10, midfoot region 12, and heel region 14 and corresponding with opposite sides of article 100. More particularly, lateral side 16 corresponds with an outer side area of the foot (i.e., a surface that faces away from the other foot), and medial side 18 corresponds with an inner side area of the foot (i.e., a surface that faces toward the other foot). Forefoot region 10, midfoot region 12, and heel region 14, as well as lateral side 16 and medial side 18 are not intended to demarcate precise areas of article 100. Rather, forefoot region 10, midfoot region 12, and heel region 14, as well as lateral side 16, medial side 18, are intended to represent general areas of article 100 to aid in the following discussion. In addition to article 100, forefoot region 10, midfoot region 12, and heel region 14, as well as lateral side 16, medial side 18 may also be applied to sole structure 110, upper 120, and individual elements thereof.

In an exemplary embodiment, sole structure 110 is secured to upper 120 and extends between the foot and the ground when article 100 is worn. Upper 120 defines an interior void within article 100 for receiving and securing a foot with respect to sole structure 110. The void is shaped to accommodate the foot and extends along a lateral side of the foot, along a medial side of the foot, over the foot, around the heel, and under the foot. Upper 120 may also include a collar located in at least heel region 14 and forming throat opening 140. Access to the interior void of upper 120 is provided by throat opening 140. More specifically, the foot may be inserted into upper 120 through throat opening 140, and the foot may be withdrawn from upper 120 through throat opening 140.

In an exemplary embodiment, upper 120 may be formed from a boot (bootie) 122. Boot 122 may be a one-piece element that completely covers the top, sides, and bottom of a wearer's foot. Portions of upper 120 (including boot 122) may be formed from one or more of a variety of material elements (e.g., textiles, polymer sheets, foam layers, leather, synthetic leather) that may form a majority of upper 120 or portions that may be stitched or bonded together to form upper 120 that defines a void within article 100. In one embodiment, boot 122 may form a majority of the exterior surface of upper 122. In other embodiments, upper 120 may be a conventional upper formed from multiple material element portions and may include edges that are attached to a sock or strobel sock to extend under the foot and close the interior void of upper 120.

In some embodiments, article 100 may include lacing system 130. Lacing system 130 extends forward from a collar and throat opening 140 in heel region 14 across an area corresponding with an instep of the foot in midfoot region 12 to an area adjacent forefoot region 10. Lacing system 130 includes a number of components configured to secure the foot within upper 120 of article 100, and may include additional or alternative components than those illustrated and described herein that are conventionally included in footwear uppers. In this embodiment, lace 136 extends through the various lace-receiving elements to allow the wearer to modify dimensions of upper 120 to accommodate proportions of the foot. In an exemplary embodiment, lace receiving elements are configured as a plurality of lace apertures 134. More specifically, lace 136 allows the wearer to tighten upper 120 about the foot, and lace 136 allows the wearer to loosen upper 120 to facilitate entry and removal of the foot from the interior void (i.e., through ankle opening 140). Lace 136 is shown in fig. 1, but for ease of illustration of the remaining components of article 100, lace 136 has been omitted from the remaining figures.

As an alternative to multiple lace apertures 134, upper 120 may include other lace-receiving elements, such as loops, eyelets, and D-rings. In addition, upper 120 includes a tongue 124, and when disposed within article 100, tongue 124 extends over the foot of the wearer to enhance the comfort of article 100. In this embodiment, tongue 124 is integrally formed with boot 122. In other embodiments, tongue 124 may be a separate component that is movable within the opening between the opposing lateral and medial sides of upper 120.

In one embodiment, the lacing system 130 may also include a support wrap (support wrap) 132. Support wrap 132 extends over the outside of boot 122 and includes lace apertures 134. In the exemplary embodiment, support wrap 132 extends between a lower region of upper 120, where upper 120 and sole structure 110 are coupled, and a lacing region, where lace 136 extends through lace apertures 134 above the top of upper 120. With this configuration, lace apertures 134 of lacing system 130 may be disposed on support wrap 132 separate from boot 122 to allow boot 122 to have a configuration without any lace-receiving elements. In other embodiments, one or more lace receiving elements, including lace apertures 134, may alternatively or additionally be located on boot 122 of upper 120.

In some embodiments, sole structure 110 may include multiple components that individually and/or collectively may provide article 100 with a number of attributes, such as support, rigidity, flexibility, stability, cushioning, comfort, reduced weight, traction, and/or other attributes. In a variety of athletic activities, the performance of skills involved in such athletic activities may be based on the precise placement and interaction of the wearer's foot with the surface on which the activity is performed. Accordingly, the typical cushioning found in the sole structures of footwear used in such activities may reduce the amount of sensory feedback that a wearer may feel from surfaces through the sole of the footwear. This can adversely affect their ability to position their feet, as well as the ability to interact with the surface on which the activity is being performed. For example, in athletic and other athletic activities where weight shifting or cutting movements are common, sensory feedback to the wearer's foot regarding the state of the surface and the amount of grip or force applied at various locations on the wearer's foot may be helpful to the wearer.

In an exemplary embodiment, article 100 includes a sole structure 110 having a sole body portion 112 and a plurality of sensory node elements 114. A plurality of sensory node elements 114 are located at discrete locations across multiple zones of sole structure 110 to provide sensory feedback to the wearer's foot at these discrete locations for assisting athletic activities. In addition, the plurality of sensory node elements 114 may also provide a "push-off surface" for the wearer's foot within the interior of the article of footwear.

In an exemplary embodiment, the components of sole structure 110 may be formed from suitable materials for achieving the desired performance attributes. The main sole portion 112 may be made of any suitable rubberGlue, polymer, composite and/or metal alloy materials. Exemplary materials may include thermoplastic and thermoset polyurethanes, polyesters, nylons, polyether block amides, alloys of polyurethane and acrylonitrile butadiene styrene, carbon fiber, poly (p-phenylene terephthalamide), para-aramid fiber, for example,) Titanium alloy and/or aluminum alloy. In some embodiments, the sole body portion 112 may be made of a durable and wear resistant material (e.g., rubber). Other suitable materials will be recognized by those skilled in the art.

In some embodiments, plurality of sensory node elements 114 may be made of similar materials as sole body portion 112, including any of the materials described above as being suitable for sole structure 110. In an exemplary embodiment, the plurality of sensory node elements 114 may be made of a material having a lower density or less stiffness than the sole body portion 112. For example, in some embodiments, plurality of sensory node elements 114 may be formed from a resilient polymer foam material, such as Polyurethane (PU) or Ethylene Vinyl Acetate (EVA). In other embodiments, the plurality of sensory node elements 114 may be formed of a less dense rubber or polymer material than the sole body portion 112. In other embodiments, the plurality of sensory node elements 114 and the sole body portion 112 may be formed from the same material.

Fig. 1-3 illustrate different views of article 100. As shown in fig. 1, sole structure 110 may include a plurality of sensory node elements 114. The sensory node element 114 may be exposed through an aperture 714 (shown in fig. 7-12) in the sole body portion 112. Accordingly, a portion of plurality of sensory node elements 114 may be exposed to the exterior of article 100 and configured to contact the ground. In this embodiment, bottom surfaces 115 of plurality of sense node elements 114 are oriented to be ground engaging surfaces of plurality of sense node elements 114. Opposing top surfaces 116 (shown in fig. 5) of plurality of sensory node elements 114 are disposed opposite the ground and face an interior of upper 120.

In an exemplary embodiment, sole body portion 112 includes a lower outsole surface 113, with lower outsole surface 113 also exposed to an exterior of article 100 and configured to contact the ground. An opposite upper surface 111 of sole body portion 112 is disposed opposite the ground and facing an interior of upper 120 in a similar orientation as top surfaces 116 of plurality of sensory node elements 114.

In some embodiments, sole structure 110 includes a plurality of sensory node elements 114, with the plurality of sensory node elements 114 being selectively disposed within different areas and/or portions of article 100 to provide sensory feedback at specific locations of the wearer's foot. In the exemplary embodiment shown in fig. 1-12, a plurality of sense node elements 114 are located at a plurality of discrete locations within each of forefoot region 10, midfoot region 12, and heel region 14. Additionally, the location of plurality of sensory node elements 114 may vary between lateral side 16 and medial side 18. Referring to fig. 2, lateral side 16 of article 100 is illustrated. In this embodiment, plurality of sensory node elements 114 are primarily disposed in midfoot region 12 and heel region 14 of sole structure 110. The remainder of sole structure 110 extending forward to the toe area of article 100 is formed by a sole body portion 112.

Referring now to fig. 3, medial side 18 of article 100 is illustrated. In this embodiment, a plurality of sensory node elements 114 are disposed in forefoot region 10, heel region 14, and at least partially in midfoot region 12. The plurality of sensory node elements 114 on medial side 18 extend further toward a toe area of article 100 in forefoot region 10 of sole structure 110 than lateral side 16. Additionally, one set of multiple sensory node elements 114 disposed in heel region 14 is separated and spaced apart from another set of multiple sensory node elements 114 disposed in midfoot region 12 and forefoot region 10 by a gap formed by sole body portion 112.

Although the figures illustrate embodiments that provide sensory node elements disposed at discrete locations across substantially all of the area of the foot, in some embodiments, sole structure 110 may include sensory node elements corresponding to different discrete locations that are targeted at some portions of the foot and not others. For example, in some embodiments, sensory node elements may be disposed only in forefoot region 10 of article 100. In other embodiments, sensory node elements may be disposed in forefoot region 10 and heel region 14, but not in midfoot region 12, of article 100.

In different embodiments, the dimensions of the sensory node elements may vary to provide desired performance for the activity for which article 100 is to be used. In an exemplary embodiment, each of the plurality of sensory node elements 114 may be substantially the same size. The dimensions of plurality of sensory node elements 114 may be selected to be large enough to provide sensory feedback to the foot of the wearer. In one embodiment, the plurality of sense node elements 114 may have a diameter of approximately 1 inch. An exemplary range of diameters suitable for providing sensory feedback may be approximately from 0.75 inches to 1.25 inches. In some cases, the diameter may be larger or smaller. In other embodiments, the size of each of the plurality of sensory node elements 114 may be different depending on the sensitivity of the portion of the foot for which sensory feedback is desired. For example, in locations where the foot is more sensitive, smaller diameter sensory node elements may be provided, while in locations where the foot is less sensitive, larger diameter sensory node elements may be provided to increase the ability of the sensory node elements to effectively provide sensory feedback to the user's foot. In addition, the density or proximity of the sensory node elements to each other may also vary depending on performance and sensitivity considerations.

Figure 4 illustrates a bottom view of the bottom side of sole structure 110 of article 100. Sole structure 110 extends along a longitudinal length of article 100 between a toe end 400 located at a front of forefoot region 10 to a heel end 410 located at a rear of heel region 14. In an exemplary embodiment, a plurality of sensory node elements 114 are located at a plurality of discrete locations within each of forefoot region 10, midfoot region 12, and heel region 14.

In some embodiments, a plurality of sets of sensory node elements 114 may be located within forefoot region 10 and extend along a medial perimeter edge on medial side 18. In this embodiment, forefoot group of sense node elements 114 includes first sense node element 210, second sense node element 211, third sense node element 212, fourth sense node element 213, fifth sense node element 214, sixth sense node element 215, seventh sense node element 216, and eighth sense node element 217. As shown in fig. 4, first and second sense node elements 210 and 211 are disposed near a toe end 400 of sole structure 110, and seventh and eighth sense node elements 216 and 217 are disposed rearward near midfoot region 12.

In one embodiment, the sets of multiple sensory node elements 114 disposed in forefoot region 10 may be disposed in pairs, with one sensory node element of each pair being located along a medial peripheral edge of sole structure 110 and the other sensory node element of the pair being located more inward toward the center of sole structure 110. For example, each of first, third, fifth, and seventh sense node elements 210, 212, 214, and 216 are disposed along the medial perimeter edge, while second, fourth, sixth, and eighth sense node elements 211, 213, 215, and 217 are disposed inward from the medial perimeter edge and toward the center of sole structure 110.

In an exemplary embodiment, another set of multiple sensory node elements 114 may be located within midfoot region 12 and extend across sole structure 110 in a lateral direction. In this embodiment, the midfoot group of sense node elements 114 includes a ninth sense node element 220, a tenth sense node element 221, an eleventh sense node element 222, a twelfth sense node element 223, a thirteenth sense node element 224, a fourteenth sense node element 225, a fifteenth sense node element 226, a sixteenth sense node element 227, and a seventeenth sense node element 228 extending between the medial perimeter edge on medial side 18 to the lateral perimeter edge on lateral side 16. As shown in fig. 4, ninth and fourteenth sensing node elements 220, 225 are disposed along a medial perimeter edge on medial side 18 of sole structure 110, and thirteenth and seventeenth sensing node elements 224, 228 are disposed along a lateral perimeter edge on lateral side 16 of sole structure 110.

In addition to the plurality of sensory node elements 114 extending laterally across sole structure 110 in midfoot region 12, article 100 may also include some of the plurality of sensory node elements 114 extending rearward in the longitudinal direction toward heel end 410 in midfoot region 12. In this embodiment, eighteenth and nineteenth sensory node elements 229 and 230 extend rearward along the lateral perimeter edge toward heel end 410 in heel region 14. Additionally, twentieth sensory node element 231 may similarly extend along a lateral perimeter edge in heel region 14.

In an exemplary embodiment, another set of multiple sensory node elements 114 may be located within heel region 14 and extend in a lateral direction across sole structure 110. In this embodiment, in addition to the twentieth sensory node element 231, the heel group of sensory node elements 114 includes a twenty-first sensory node element 240, a twenty-second sensory node element 241, a twenty-third sensory node element 242, a twenty-fourth sensory node element 243, and a twenty-fifth sensory node element 244. Together, the twenty-first, twenty-second, twenty-third, twenty-fourth, and twenty-fifth sense node elements 240, 241, 242, 243, and 244 extend across sole structure 110 from medial side 18 to lateral side 16 at heel end 410 of heel region 14.

In one embodiment, the arrangement of multiple sets of multiple sensory node elements 114 at discrete locations on sole structure 110 may divide sole body portion 112 into one or more regions, as shown in fig. 4. For example, outsole surface 113 of main sole portion 112 may be exposed at a first area corresponding with lateral side 16 of forefoot region 10 and at a second area corresponding with a portion of midfoot region 12 and heel region 14 along a medial peripheral edge on medial side 18 of sole structure 110. In some embodiments, outsole surface 113 may also include additional features that help provide traction to sole structure 110. In one embodiment, a plurality of grooves 200 are provided in the outsole surface 113 of the sole body portion 112. The plurality of grooves 200 may be depressions or recesses in the sole body portion 112 that extend below and around the outsole surface 113. In this embodiment, the plurality of grooves 200 are arranged in an approximately concentric arrangement, with each groove being substantially evenly spaced from an adjacent groove. With this configuration, outsole surface 113 of sole body portion 112 may help provide traction or grip to article 100.

Fig. 5 illustrates an interior top view of the medial side of sole structure 110 of article 100, with upper 120 and sole body portion 112 shown in outline. In some embodiments, each of the plurality of sense node elements 114 may have a top surface 116 at a top end, each sense node element having a smaller diameter at the top end than at an opposite bottom end where the bottom surface 115 is located. As will be described further below, top surface 116 of each of plurality of sensory node elements 114 is attached to base layer 128 of upper 120. In this case, base layer 128 is the bottom portion of shoe 122 that extends under the wearer's foot. In other cases where article 100 includes other embodiments of upper 120, base layer 128 may be formed from a shoe insert, a strobel sock, or an insole that encloses upper 120.

Fig. 6 illustrates an exemplary embodiment of sole structure 110, wherein the discrete locations of the plurality of sensory node elements 114 approximately correspond to contact patches of a wearer's foot 600. That is, the contact surface of the foot represents the typical location of contact between the wearer's bare foot and the surface. In this embodiment, sole structure 110 has been provided with a plurality of sensory node elements 114 disposed at locations corresponding to this contact surface to provide sensory feedback to the wearer's foot 600 at the same locations that would receive feedback when the barefoot contacts the surface. With this configuration, sole structure 110 and plurality of sensory node elements 114 may provide a sensation similar to that of a bare foot contacting the surface or sensory feedback on the force and topology of the surface. The feedback may be used by the wearer when participating in or performing athletic activities. In addition, the plurality of sensory node elements 114 may provide a "push-off" surface for the foot on the interior of the article of footwear to aid in athletic skills (athletic maneuvers) or cutting motions.

In this embodiment, the forefoot group of plurality of sense node elements 114, including first sense node element 210, second sense node element 211, third sense node element 212, fourth sense node element 213, fifth sense node element 214, sixth sense node element 215, seventh sense node element 216, and eighth sense node element 217, corresponds approximately with the portion of the big toe of foot 600. A midfoot group of multiple sense node elements 114, including ninth sense node element 220, tenth sense node element 221, eleventh sense node element 222, twelfth sense node element 223, thirteenth sense node element 224, fourteenth sense node element 225, fifteenth sense node element 226, sixteenth sense node element 227, and seventeenth sense node element 228, generally corresponds with a portion of the ball and metatarsals of foot 600.

Similarly, the heel group of sense node elements 114 that includes the twenty-first sense node element 240, the twenty-second sense node element 241, the twenty-third sense node element 242, the twenty-fourth sense node element 243, and the twenty-fifth sense node element 244 generally corresponds with the heel of the foot 600. In addition, the eighteenth, nineteenth, and twentieth sensory node elements 229, 230, 231 extend rearwardly along the lateral perimeter edge and correspond to the lateral portion of the foot 600 that is exterior between the metatarsal and heel. With this arrangement, the plurality of sensory node elements 114 of sole structure 110 may be configured to provide sensory feedback to the wearer's foot 600 at a plurality of discrete locations. Such sensory feedback may be used by the wearer when participating in athletic activities or performing athletic activities.

Fig. 7 illustrates an exploded perspective view of article 100, article 100 including components of each of sole structure 110, upper 120, and lacing system 130. As shown in fig. 7, sole structure 110 includes a plurality of sensory node elements 114 and a sole body portion 112. The sole body portion 112 includes apertures 714 that receive the plurality of sensory node elements 114. The apertures 714 allow the top surface 116 of the plurality of sense node elements 114 to be attached to the upper 120 and allow the plurality of sense node elements 114 to move independently of the sole body portion 112 when the bottom surface 115 of the plurality of sense node elements 114 contacts the surface.

In an exemplary embodiment, the arrangement of multiple sets of multiple sensory node elements 114 at discrete locations on sole structure 110 may separate sole body portion 112 into one or more regions, as described above. In this embodiment, the sole body portion 112 may include a first region 710 corresponding with the lateral side 16 of the forefoot region 10 and a second region 712 corresponding with a portion of the midfoot region 12 and heel region 14 along the medial peripheral edge on the medial side 18 of the sole structure 110. In this embodiment, a midfoot set of a plurality of sensory node elements 114 is disposed between a first region 710 of the sole body portion 112 and a second region 712 of the sole body portion 112.

In other embodiments, the sole body portion 112 may maintain a single piece with a grid or other support structure for coupling one or more regions between which the plurality of sensory node elements 114 are located. Additionally, apertures 714 may each correspond to a single one of the plurality of sensory node elements 114, or apertures 714 may be configured to receive multiple ones of the plurality of sensory node elements 114. In some cases, combinations of apertures 714 may be used at different portions of sole structure 110, such that some apertures 714 include one sensory node element, while other apertures 714 include multiple sensory node elements.

Referring again to fig. 7, in some embodiments, the support wrap 132 of the lacing system 130 may be provided by separate components for each of the lateral side 16 and the medial side 18 of the upper 120. In this embodiment, the support wrap includes a medial support portion 700 on the medial side 18 and a lateral support portion 702 on the lateral side 16. Medial support portion 700 and lateral support portion 702 together form support wrap 132 and include a plurality of lace apertures 134 for receiving lace 136. Support wrap 132 extends over the outside of boot 122 and helps secure article 100 to the wearer's foot. The support wrap 132, including each of the medial support portion 700 and the lateral support portion 702, may be coupled to a portion of the sole structure 110, a portion of the upper 120, or both.

Fig. 8-10 provide exemplary representative illustrations of sensory feedback provided to a wearer's foot by sole structure 110 and plurality of sensory node elements 114. In some embodiments, a boot 122 forming upper 120 may be coupled to sole body portion 112 and plurality of sensory node elements 114. As shown in fig. 8, base layer 128 is a bottom portion of boot 122 that is configured to extend under the foot of a wearer. Base layer 128 is coupled to upper surface 111 of sole body portion 112 and is also coupled to top surface 116 of plurality of sensory node elements 114. In this embodiment, each of the plurality of sense node elements 114 is shown within a respective one of the apertures 714 in the sole body portion 112. This arrangement allows the top surface 116 of each of the plurality of sensory node elements 114 to be attached to the base layer 128 of the shoe 122. Further, the plurality of sensory node elements 114 are not attached or coupled to the main sole body portion 112 such that the plurality of sensory node elements 114 are allowed to oscillate and move independently at least in a vertical direction within the apertures 714 in the main sole body portion.

Referring now to fig. 9, a foot 600 is shown that is positioned within the interior void of upper 120 in article 100. The bottom of the foot 600 contacts portions of the base layer 128. Article 100 is shown in an uncompressed state here before article 100 is placed in contact with ground 900. In this uncompressed state, each of the plurality of sensory node elements 114 has a top surface 116, and the top surface 116 is approximately flush or flat with the upper surface 111 of the main sole body portion 112. A plurality of sense node elements 114 are shown in an uncompressed state within apertures 714 in the main sole body portion 112, including a first sense node element 210, a third sense node element 212, a fifth sense node element 214, a seventh sense node element 216, a ninth sense node element 220, a fourteenth sense node element 225, a twenty-first sense node element 240, and a twenty-fourth sense node element 243.

When the foot 600 of the wearing article 100 is stepped on the ground 900, the article 100 is placed in a compressed state. Referring now to fig. 10, article 100 is shown being compressed by foot 600 against ground 900. In various instances, the ground 900 may have one or more objects or features that are not flat. In this embodiment, the ground 900 includes a first object 902 and a second object 904. The first object 902 and the second object 904 may be rocks, debris, or any other change in the surface topology of the ground 900, such as a hill, a mound, a turf, or a depression.

In this embodiment, one or more of plurality of sensory node elements 114 may transmit or relay sensory feedback regarding the state or topology of ground 900 through sole structure 110 to foot 600 when article 100 is in a stressed state. As shown in FIG. 10, a first object 902 on the ground 900 may push each of the third, fifth and seventh sense node elements 212, 214, 216 upward through an aperture 714 in the sole body portion 112. This upward vertical movement of third, fifth, and seventh sense node elements 212, 214, 216 causes top surface 116 to push base layer 128 upward and contact foot 600 in an area corresponding to the location of first object 902 on ground 900. With this sensory feedback, the wearer may perceive the presence of an object or uneven area of ground 900 disposed below forefoot region 10 of article 100.

Similarly, when article 100 is under compression caused by foot 600, second object 904 on ground surface 900 may push each of twenty-first and twenty-fourth sensory node elements 240, 243 upward through apertures 714 in main sole body portion 112. This upward vertical movement of the twenty-first and twenty-fourth sensory node elements 240, 243 causes the top surface 116 to push the base layer 128 upward and contact the foot 600 in an area corresponding to the location of the second object 904 on the floor 900. With this sensory feedback, the wearer may perceive the presence of another object or uneven area of the ground 900 disposed below the heel region 14 of article 100.

By providing sole structure 110 of article 100 with a plurality of sensory node elements 114 disposed at discrete locations on sole structure 110 that generally correspond with the contact surface of a wearer's foot, sensory feedback may similarly be provided to corresponding portions of the foot and impart information to the wearer regarding the state or topology of the ground in contact with sole structure 110 of article 100. In addition, a plurality of sensory node elements 114 may extend into the interior of article 100 and provide a "push-off" surface for the user's foot to perform motor skills or cutting motions.

Fig. 11 and 12 illustrate independent movement of an exemplary one of the plurality of sensory node elements 114 relative to the main sole body portion 112 and the base layer 128 of the shoe 122. Referring now to FIG. 11, the sensory node element 114 is positioned in the aperture 714 of the main sole body portion 112 and moves at least vertically within the aperture 714 independently of the main sole body portion 112. That is, although portions of the sensory node element 114 may contact portions of the sole body portion 112 when the sensory node element 114 is moved through the aperture 714, the sole body portion 112 and the sensory node element 114 are not directly coupled or attached to one another. With this arrangement, the sensory node element 114 can rock and move independently of the sole body portion 112, and the sensory node element 114 can be vertically displaced relative to the outsole surface 113 of the sole body portion 112.

In an exemplary embodiment, the sole body portion 112 may have a first height H1. The first height H1 corresponds to a thickness of the sole body portion 112 in a vertical direction extending between the foot of the wearer and the ground. The sense node elements 114 may have a second height H2, which second height H2 corresponds to the height or thickness of the sense node elements 114 in the same vertical direction. In this embodiment, the second height H2 of the sensory node element 114 is greater than the first height H1 of the sole body portion 112. With this arrangement, the bottom surface 115 of the sense node element 114 extends higher than the outsole surface 113 of the sole body portion 112, such that the bottom surface 115 of the sense node element 114 will contact the ground first, generally before the outsole surface 113 of the sole body portion 112.

In this embodiment, the aperture 714 in the sole body portion 112 may define an opening in the sole body portion 112 having a first width W1. The sense node element 114 is located within the opening defined by the aperture 714 and has a second width W2. In some cases where the sense node element 114 has a frustoconical shape, the second width W2 may also be the diameter of the sense node element 114. The second width W2 of the sense node element 114 is less than the first width W1 of the opening defined by the aperture 714. With this arrangement, the sensory node element 114 may fit within the aperture 714 of the sole body portion 112 with at least some clearance from the sides of the aperture 714.

In this embodiment, base layer 128 of shoe 122 includes an inner surface 1100 that faces the interior void of upper 120 and an outer surface 1102 that faces away from article 100 and faces the ground. The outer surface 1102 of the base layer 128 is attached to the upper surface 111 of the sole body portion 112 and also to the top surface 116 of the sensory node element 114. In FIG. 11, sensory node element 114 is shown in an uncompressed state such that top surface 116 is approximately flat or flush with upper surface 111 of main sole body portion 112. Similarly, in the area of shoe 122 shown in FIG. 11, the inner surface 1100 of base layer 128 is also of approximately uniform or equal height above both top surface 116 and upper surface 111.

Referring now to FIG. 12, the sense node elements 114 are shown in a stressed state, e.g., as described above with reference to FIG. 10. In a compressed state, the bottom surface 115 of the sense node element 114 contacts the ground 900, and the bottom surface 115 of the sense node element 114 moves toward a direction closer to the outsole surface 113 of the sole body portion 112. This movement also forces the top surface 116 of the sense node element 114 upward against the outer surface 1102 of the base layer 128. The sensory node element 114 is allowed to move independently of the sole body portion 112 through the aperture 714, thereby causing a localized area of the base layer 128 attached to the top surface 116 of the sensory node element 114 to move upward to form a raised interior surface 1110 of the base layer 128. Raised interior surface 1110 may then contact the underside of the wearer's foot to provide sensory feedback about ground 900.

In this embodiment, raised inner surface 1110 extends a first distance D1 above inner surface 1100. The first distance D1 is approximately equal to the difference between the second height H2 of the sensory node element 114 and the first height H1 of the sole body portion 112. That is, when in a stressed state, top surface 116 of sense node element 114 elevates base layer 128 such that raised inner surface 1110 extends above inner surface 1100 by approximately the same amount that bottom surface 115 of sense node element 114 extends above outsole surface 113 of main sole body portion 112 when article 100 is in an unstressed state.

With this configuration, the amount of first distance D1 may be configured as desired based on the selection of first height H1, second height H2, or both. For example, in some cases, the raised inner surface 1110 of the base layer 128 can be a greater or lesser distance to contact portions of the wearer's foot. Selecting a larger or smaller first height H1 for sole body portion 112 and/or a smaller or larger second height H2 for sensory node element 114 may accommodate the different distances required for raised interior surface 1110 to contact the foot.

Fig. 13 and 14 illustrate exemplary embodiments of representative ones of the plurality of sensory node elements 114. In this embodiment, the sense node element 114 includes a top end 1300 at which the top surface 116 is located and a bottom end 1302 at which the bottom surface 115 is located. A main body portion 1310 of the sense node element 114 extends between the top end 1300 and the bottom end 1302, and includes a side surface 1312. In one embodiment, the top end 1300 has a smaller diameter than the opposite bottom end 1302 so as to define an approximate frustoconical shape of the sensory node element 114. In various embodiments, the distance between top end 1300 and bottom end 1302 may be varied to vary the length of body portion 1310, and thus the height of sense node element 114. In an exemplary embodiment, the bottom surface 115 of the sense node element 114 is convex. In one embodiment, the bottom surface 115 of the sensory node element 114 may be approximately hemispherical. However, in other embodiments, the shape of the sensory node element 114 may vary, including but not limited to triangular, cylindrical, spherical, circular, and other geometric and non-geometric shapes. Moreover, in other embodiments, the bottom surface 115 may be flat or uneven.

In this embodiment, the frustoconical shape and convex bottom surface 115 of the sense node element 114 allow the sense node element to oscillate about at least two axes. As shown in fig. 13, sensory node element 114 has a first axis 20 approximately aligned with the x-axis, a second axis 30 approximately aligned with the y-axis, and a third axis 40 approximately aligned with the z-axis. In some embodiments, sensory node elements 114 may oscillate or move about two or three of first axis 20, second axis 30, and/or third axis 40. In some cases, the x-axis may be associated with a lateral direction of article 100, the y-axis may be associated with a longitudinal direction of article 100, and the z-axis may be associated with a vertical direction of article 100. However, it should be understood that the designation and selection of coordinate systems may vary.

For example, as shown in fig. 14, sense node element 114 is shown to oscillate about at least two axes such that the orientation of bottom surface 115 and top surface 116 is changed. The oscillation of sense node element 114 may be caused by the transmission of force or instability of the ground relative to article 100. With this configuration, the sensory node element 114 can oscillate about at least two axes within the aperture 714 in the main sole body portion 112 to transmit sensory feedback to the wearer's foot.

In the previous embodiment, base layer 128 of shoe 122 is shown attached to top surface 116 of sense node element 114 and upper surface 111 of sole body portion 112. In some cases, the outer surface 1102 of the base layer 128 may be attached to the upper surface 111 of the sole body portion 112 up to the edge of the opening that defines the aperture 714. For example, as shown in fig. 11 and 12. In other cases, by keeping a portion of outer surface 1102 of base layer 128 unattached to upper surface 111 of sole body portion 112, a predetermined amount of slack or resiliency may be provided to base layer 128 to accommodate upward vertical movement of top surface 116 of sense node element 114.

Referring now to fig. 15, the outer surface 1102 of the base layer 128 remains unattached to the upper surface 111 of the main sole body 112 along a margin 1500, which margin 1500 is located a predetermined distance D2 around the aperture 714 in the main sole body 112. Rim 1500 allows substrate 128 to have a predetermined amount of slack or resiliency to accommodate upward vertical movement of top surface 116 of sense node element 114 when in a stressed state. As shown in fig. 15, the rim 1500 extending a predetermined distance D2 around the aperture 714 allows the inner surface 1100 of the base layer 128 to rise to the raised inner surface 1110.

In some embodiments, the base layer 128 may be formed from a flexible or stretchable layer or film (including materials made from elastic, rubber, woven or knitted textiles, or other suitable flexible materials). In this case, the base layer 128 may stretch as needed to accommodate upward vertical movement of the top surface 116 of the sensory node element 114 when in compression. Additionally, such a flexible or stretchable layer may be elastic to help force sensory node elements 114 back to an uncompressed state when force from the foot is removed. However, in other embodiments, the base layer 128 may need to accommodate additional displacement or increased sensitivity, which may be lost if too elastic materials are used. Moreover, in other embodiments, the base layer 128 may be made of a non-stretchable or non-bendable material. Thus, in these other embodiments, alternative embodiments of using rim 1500 to attach base layer 128 to upper surface 111 of sole body portion 112, as described above with reference to fig. 15, may aid in the upward vertical movement of top surface 116 of sensory node element 114 when in a compressed state.

In the previous embodiments, multiple sensory node elements 114 have been described as being arranged in different groups at discrete locations across sole structure 110 of article 100. In these embodiments, each of the plurality of sensory node elements 114 is arranged to move independently. In alternative embodiments, the plurality of sensory node elements 114 may be arranged into one or more groups comprising at least two sensory node elements configured to move together as a unitary element. Referring now to FIG. 16, an alternative embodiment of sole structure 1610 is illustrated having a plurality of sense node elements 114 arranged in groups at discrete locations. Each group includes two or more sensory node elements 114 configured to move together as a unitary element.

As shown in fig. 16, first overall group 1620 is disposed in forefoot region 10 along a medial perimeter edge on medial side 18, second overall group 1630 is disposed in midfoot region 12 along a medial perimeter edge on medial side 18, third overall group 1640 is disposed in midfoot region 12 along a lateral perimeter edge on lateral side 16, fourth overall group 1650 is disposed in the portions of midfoot region 12 and heel region 14 extending toward heel end 410 of sole structure 1610 along a lateral perimeter edge on lateral side 16, fifth overall group 1660 is disposed on lateral side 16 of heel region 14, and sixth overall group 1670 is disposed on medial side 18 of heel region 14.

In this alternative embodiment, each of first overall group 1620, second overall group 1630, third overall group, fourth overall group 1650, fifth overall group 1660, and sixth overall group 1670 includes two or more of plurality of sense node elements 114 coupled or attached together so as to move approximately simultaneously as an overall element. With this arrangement, sensory feedback can be provided to the general area of the foot of the wearer. For example, in some cases, less sensory feedback may be needed, and more general sensory feedback regarding a larger area or region of the foot and medial side 18 and lateral side 16 may be sufficient. It should be understood that the location of the entire set of sense node elements illustrated in FIG. 16 is merely exemplary. Other combinations and configurations may be selected based on the desired sensory feedback, including combinations of individual sensory node elements and an overall set of sensory node elements in the same embodiment.

While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
