Technical Field

The present invention relates to an upper comprising a strap, a shoe comprising said upper and a method for producing the same.

Background

Everyday use of footwear and particularly athletic use place many competing demands on the article of footwear. The article of footwear should be lightweight and comfortable to wear, it should be sufficiently elastic to allow the foot to move, and it should also provide the correct level of support to prevent injury and to facilitate maximum performance.

EP3289907a1 relates to an upper for a shoe, in particular a sports shoe, comprising at least one band portion which covers at least 50% of the upper, wherein the at least one band portion comprises a plurality of connected bands. Another aspect relates to an upper for a shoe, in particular a sports shoe, comprising at least one band portion comprising a plurality of connected bands, wherein the bands are zigzag stitched to each other on their edges.

EP0960578a1 relates to a shoe which uses a moulded bottom with a series of slits on its edge or through holes in the sole, to be applied to a closed upper made of a fabric or leather strip which surrounds the back and neck of the foot.

US2002129517a1 relates to a safety shoe for protecting a person's foot against harmful injury comprising a high impact resistant shell, an internal dense foam insert, a firm toe cap, a heel cup, an insole, an outsole and a moisture dissipative material surrounding the dense foam insert. The shell includes a series of resiliently interlocking sliding straps disposed around the foot and folded between an outsole and an insole beneath the foot. Access to the boot is provided by means of a rear opening with a built-in catch to close the boot around the foot.

US2012011745a1 relates to an article of footwear comprising a plurality of straps. The connection between successive portions of the article may be enhanced by weaving a plurality of straps through apertures located in one or more successive portions. One continuous portion may comprise the tongue of the article. The attachment of the tongue to the front of the article may be enhanced by weaving a plurality of strips through the holes.

It is an object of the present invention to improve the fit and wearing comfort of existing footwear, particularly for athletic use.

Footwear for ball games, such as soccer, is subject to additional requirements that the ball should be precisely controlled. It is therefore a further object of the invention to provide an article of footwear which allows improved control of the ball.

Another object of the invention is to improve the production process of the footwear.

Disclosure of Invention

These objects are achieved by an upper and a method for producing the same according to the independent claims. The invention relates in particular to an upper comprising at least a first strip and a second strip, wherein the first strip and/or the second strip is elastic, (a) wherein the first strip comprises a first edge, (b) wherein a first portion of the first edge of the first strip is not connected to the second strip, and (c) wherein a second portion of the first edge of the first strip is connected to the second strip.

A belt in this context is any substantially two-dimensional article having a dimension in a two-dimensional range greater than a third dimension. For example, the strip may be a textile sheet, tape, strip, or the like. The textile sheet may be woven, non-woven, warp knitted or weft knitted.

An important feature of the upper according to the invention is that the first strip and the second strip are only partially connected to each other at the first edge of the first strip. However, it is to be understood that the first and second strips may be partially or completely connected to each other along another edge than the first edge, e.g. an edge substantially perpendicular or substantially parallel to the first edge. "substantially perpendicular" in this context means an angle between 60 and 120 degrees. "substantially parallel" means at an angle between 0 and 30 degrees.

The upper according to the invention can be used for any type of shoe, for example for sports shoes such as running shoes, football shoes, golf shoes, tennis shoes, etc., or for hiking shoes, hiking boots, etc.

The upper according to the present invention provides a better fit than known uppers in the art. In particular, the upper readily accommodates different foot shapes, such as during athletic activities, and may be "keyed" to provide a better level of support when it is worn. Because the first and second belts are only partially connected to each other along the first edge, the first and second belts are movable and can move relative to each other. In particular, the first portion may have slack to move relative to the second strap when the upper is unworn or in a stretched condition. In other words, the first portion is movable relative to the second belt. For example the first belt may be moved away from the second belt or in a direction parallel to the surface of the second belt.

The upper, therefore, provides a greater amount of flexibility than those provided by uppers known in the art, but still has a comfortable level of support. Furthermore, it is possible to insert the foot more easily and comfortably in the upper according to the invention, since the collar opening can be opened more easily and more widely.

With respect to the elasticity of the first and/or second band, the term "elasticity" is understood from the viewpoint of a person skilled in the art of footwear development. Since at least one of the two belts is elastic, wearing comfort and fit are further improved. The first and/or second belt may for example comprise elastane and/or polyester fibres.

The first and second bands may at least partially overlap. Increased support may be created and provided to the foot of the wearer in areas of the upper where the first and second straps overlap. It is also possible that the first and second bands completely overlap.

The first portion of the first edge of the first strap may be disposed closer to the toe area of the upper than the second portion of the first edge of the first strap. Therefore, the toe region of the upper has greater elasticity and allows toe movement, thereby improving wearing comfort.

The second portion of the first edge of the first band may be attached to the second band by stitching created by sewing. Sewing is a preferred method that allows the second portion of the first edge of the first strap to be securely attached to the second strap even if the first portion of the first edge of the first strap is not attached to the second strap. Furthermore, the transition between the first portion and the second portion of the first edge of the first strip may be very precise.

At least a portion of the first strap or a portion of the second strap may be in a pre-stretched condition when the upper is not worn. This is also possible for the third or fourth band (if present) or any other band (if present). In other words, at least a portion of the first strap or a portion of the second strap may be under tension when the upper is not worn by the wearer and is not disposed on a footwear last or shoe last. This may be accomplished by applying tension to the first and/or second belts prior to sewing the second portion of the first edge of the first belt to the second belt, as described in more detail below. Therefore, a more snug and better fit can be achieved. It should be noted that the first and second belts are adaptable such that at least a portion of the first belt or a portion of the second belt is in a pre-stretched condition. This may apply regardless of whether the first portion and/or the second portion of the first edge of the first strip is (is) connected to the second strip.

The first edge of the first strip may further include a third portion disposed adjacent to the second portion, but not adjacent to the first portion, wherein the third portion of the first edge of the first strip may not be connected to the second strip. Thereby, the elasticity and wearing comfort of the upper can be further improved.

The upper may further include a third strap disposed at least partially between the first strap and the second strap. In particular, the third strip may partially overlap the first strip and partially overlap the second strip. In this way, the stability and fit provided by the upper may be improved.

The first edge of the first belt may be at least partially unconnected to the third belt. For example, the first edge of the first belt may not be connected to the third belt except perhaps at a point at the first edge end. The linear dimension of the point in any direction is much smaller than the length of the first edge. The point may be one or more sutures. Therefore, the third strap is relatively freely movable with respect to the first strap and thereby allows comfortable movement of the foot covered by the upper.

The upper may further include a fourth strip, wherein the third strip may include a first edge thereof and the fourth strip may include a first edge thereof. The first portion of the first edge of the third strip is not connected to the fourth strip and the second portion of the first edge of the third strip is connected to the fourth strip. It is to be understood that the first edges of the different strips are generally separate entities.

In other words, the third and fourth bands may be only partially connected to each other along the first edge of the third band, similar to the first and second bands being connected along the first edge of the first band. In particular, the first portion of the first edge of the third strip may have slack to move relative to the fourth strip when the upper is unworn or in a stretched condition. In other words, the first portion of the first edge of the third band may be movable relative to the fourth band. For example, the third belt may be moved away from the fourth belt or in a direction parallel to the surface of the fourth belt. Thereby, good wearing comfort is achieved.

The second band may be at least partially disposed between the third band and the fourth band. In particular, the second band may partially overlap the third band and partially overlap the fourth band. In other words, the arrangement of the first, second, third and fourth bands may be staggered, for example in an alternating manner (left/right). This arrangement has been found to be advantageous for a particularly comfortable wearing experience.

The first angle formed between the first edge of the first strip and the first edge of the third strip may be less than 130 degrees, preferably less than 110 degrees. The first angle is preferably greater than 10 degrees, more preferably 30 degrees, most preferably 45 degrees. This range of angles has been found to provide a good balance between providing support for the foot on the one hand and allowing expansion of the space available for the foot during exercise on the other hand. It is to be understood that the angle is measured when the upper is not worn in a shape similar to the target shape when worn.

A second angle may be formed between the first edge of the second band and the first edge of the fourth band, wherein the second angle may be less than the first angle. It is to be understood that the first angle need not be less than 130 degrees in such an arrangement. The first angle may be disposed closer to a toe region of the upper than the second angle. In this manner, the upper provides improved fit.

It is to be understood that the upper may include any number of straps greater than 1. A plurality of angles may be formed between the first edges of the bands such that the angles decrease continuously from a toe region toward a heel region of the upper.

The strips may at least partially overlap such that a first area of the upper includes a first number of layers and a second area of the upper includes a second number of layers. The first number of layers may be greater than the second number of layers. It has been found that this arrangement is particularly advantageous to create a first region of increased protection for the upper and a second region of increased elasticity.

The first region may be disposed proximate to the metatarsal region, and the second region may be disposed closer to a heel region of the upper than the first region. In many sports, the metatarsal region requires additional support. The second area is preferably closer to a heel area of the upper to allow the foot to comfortably enter the upper.

The upper may further include a retaining strap disposed in a direction from a medial region to a lateral region of the upper. In other words, the retaining strap may extend laterally along the foot. In particular, the retaining band may be arranged in the metatarsal region. It has been found that for some applications, it may be preferable to increase the support of the foot in the metatarsal region to ensure a good fit of the upper. For such applications, a retaining band may be advantageous. The performance of the retention strap may be similar to the first, second, third and fourth straps, and in particular, the retention strap and/or any other strap may be elastic.

The upper may further include a coating that at least partially covers one or more of the straps. In other words, the coating may cover at least one of the bands, and for the respective band, the coating may at least partially cover the band. The coating may comprise polyurethane or any other suitable material. The coating advantageously improves the water resistance of the upper and prevents dirt from entering the upper. The coating may also be used to affect other properties in the coated areas of the upper, such as the tensile strength, stiffness, or surface friction of the upper (e.g., between the ball and the upper).

The upper may be lace-free. It has been found that the laces can have a detrimental effect on the ball control of the shoe in ball games such as soccer. Therefore, it is advantageous that the upper is lace-free. However, as is known in the art, a lace-free upper may not provide optimal fit and support for the foot. The upper according to the present invention overcomes these problems and therefore provides a desirable fit and better ball control.

The invention further relates to a shoe comprising an upper according to the invention. The footwear according to the invention therefore advantageously provides excellent fit, good ball control and a good level of support for the foot.

The invention further relates to a method of producing an upper, comprising providing at least a first strip and a second strip, wherein the first strip and/or the second strip is elastic, and wherein the first strip comprises a first edge. The method includes attaching the second portion of the first edge of the first strap to the second strap such that the first portion of the first edge of the first strap is not attached to the second strap.

In other words, the first edge of the first strap may be connected to the second strap such that a first portion of the first edge of the first strap is not connected to the second strap and such that a second portion of the first edge of the first strap is connected to the second strap.

Many aspects and advantages of the method of manufacturing an upper according to the present invention have been described above in the context of corresponding aspects of the upper.

As described above, the first portion of the first edge of the first strap may move relative to the second strap when the upper is not worn.

The method of manufacturing an upper may further include at least partially overlapping the first strip and the second strip.

The method of manufacturing an upper may further include disposing a first portion of the first edge of the first strap closer to a toe area of the upper than a second portion of the first edge of the first strap.

Attaching the second portion of the first edge of the first band to the second band may include sewing. Stitching may comprise any method known in the art, such as linear stitching or zigzag stitching, particularly zigzag stitching. The former requires less space, while the latter may provide improved stability.

The sewing may include applying tension to the first and/or second belts prior to making the seam. It is explicitly noted that in particular this aspect of sewing may be performed irrespective of whether the first and second portions of the first edge of the first band are (not) attached to the second band. In other words, for the method of manufacturing the upper, the technique of applying tension prior to stitching may be applied to one or more strips of the upper, which may then be partially joined, fully joined, or not joined to each other.

The first belt may further include a second edge disposed opposite the first edge. Applying tension may include pulling a first edge of the first belt a first distance and pulling a second edge of the first belt a second distance, wherein the first distance is different than the second distance. Preferably, the drawing is performed in the longitudinal direction of the first edge and the second edge, respectively. A tension difference is generated between the first edge and the second edge. Such a tension difference can be advantageously used to create a three-dimensional shape. Also in this respect it is particularly noted that it may be applied irrespective of whether the first and second portions of the first edge of the first tape are (not) connected to the second tape.

The first edge of the first belt may further comprise a third portion, and the methods described herein may further comprise: the third portion is disposed adjacent to the second portion, but not adjacent to the first portion, such that the third portion of the first edge of the first strip is not connected to the second strip, as described above.

The method of manufacturing an upper may further include providing a third strip and disposing the third strip at least partially between the first strip and the second strip, as described above. In particular, the third band may partially overlap the first band and partially overlap the second band.

The third belt may be arranged such that the first edge of the first belt may be at least partially unconnected to the third belt. For example, the first edge of the first belt may not be connected to the third belt except possibly at a point at the first edge end of the first belt.

The third strip may include a first edge and a second edge disposed opposite the first edge. Applying tension may additionally or alternatively include pulling the first edge of the third belt a third distance and pulling the second edge of the third belt a fourth distance, wherein the third distance is different than the fourth distance. This principle can be applied to any edge of any belt and the corresponding opposite edge to create a tension difference on any of the belts.

The method of manufacturing an upper may further include providing a fourth strip, and joining the second portion of the first edge of the third strip to the fourth strip such that the first portion of the first edge of the third strip is not joined to the fourth strip.

The method of manufacturing an upper may further include disposing a second strap at least partially between the third strap and the fourth strap. In particular, the second belt is arranged to partially overlap the third belt and to partially overlap the fourth belt.

The method of manufacturing an upper may further include forming a first angle of less than 130 degrees, preferably less than 110 degrees, between the first edge of the first strip and the first edge of the third strip. The first angle is preferably greater than 10 degrees, more preferably 30 degrees, most preferably 45 degrees.

The fourth strip of the upper may include a first edge. The method of manufacturing an upper may further include: a second angle is formed between the first edge of the second strip and the first edge of the fourth strip, and wherein the second angle is less than the first angle. It is to be understood that the first angle need not be less than 130 degrees in such an arrangement. The first angle may be disposed closer to a toe region of the upper than the second angle. The upper therefore provides improved fit.

The method of manufacturing an upper may further include at least partially overlapping the strip to form a first region of the upper including a first number of layers and a second region of the upper including a second number of layers, and wherein the first number of layers is greater than the second number of layers.

The method of manufacturing an upper may further include positioning the first area proximate to the metatarsal region and positioning the second area closer to a heel region of the upper than the first area.

The method of manufacturing an upper may further include disposing a retaining strap in a direction from a medial region to a lateral region of the upper, and attaching the retaining strap to the at least one strap.

The method of manufacturing an upper may further include at least partially covering the one or more strips with a coating. In other words, the coating may cover at least one of the strips, and for the respective strip, the coating may at least partially cover it.

The upper may be lace-free, as described above.

The invention further relates to a method of producing a shoe, comprising: (a) producing an upper as described herein, and (b) attaching a sole element to the upper.

Detailed Description

In the following, only some embodiments of the invention are described in detail. It is to be understood that the exemplary embodiments may be varied in many ways and combined with each other where compatible, and that certain features may be omitted, as long as they appear to be optional.

Fig. 1A-1C illustrate an exemplary upper 10 according to the present invention. Fig. 1A shows a top view and fig. 1B shows a side view. Upper 10 includes first strip 11 and second strip 12, (a) wherein first strip 11 includes first edge 21, (b) wherein a first portion 21a of first edge 21 of first strip 11 is not connected to second strip 12, and (c) wherein a second portion 21b of first edge 21 of first strip 11 is connected to second strip 12.

An important feature of upper 10 according to the present invention is that first strip 11 and second strip 12 are only partially connected to each other at first edge 21 of first strip 11. However, the first and second bands 11, 12 are connected to each other along second and third edges 22, 23, the second and third edges 22, 23 being different from the first edge 21. The third edge 23 is substantially perpendicular to the first edge 21 and the second edge 22 is substantially parallel to the first edge 21. First strap 11 is connected to first toe element 18a along second edge 22 and to second toe element 18b along third edge 23. In this example, each of first toe element 18a and second toe element 18b includes a band. First toe element 18a and second toe element 18b may optionally be connected to each other, e.g., to form a single element, or may be separate from each other. The exemplary upper 10 is for a soccer shoe.

In particular, the first portion 21a of the first edge 21 of the first belt 11 is movable relative to the second belt 12, as best seen from the side view shown in fig. 1B.

The first belt 11 and the second belt 12 are partially overlapping. It is also possible that the first belt 11 and the second belt 12 completely overlap.

The first portion 21a of the first edge 21 of the first strap 11 is disposed closer to the toe region 18 of the upper 10 than the second portion 21b of the first edge 21 of the first strap 11.

The second portion 21b of the first edge 21 of the first strap 11 is connected to the second strap 12 by stitching.

The upper 10 further comprises a third strip 13, which is arranged partially between the first strip 11 and the second strip 12. The first edge 21 of the first strap 11 is at least partially unconnected to the third strap 13. In one example, the first edge 21 of the first strap 11 is not connected to the third strap 13 except at point P at the end of the first edge 21. Third strap 13 is connected to first toe element 18a along second edge 22 and to second toe element 18b along third edge 23. In addition, the third belt 13 comprises a first edge 31 comprising a first portion 31a and a second portion 31 b.

The upper 10 further comprises a fourth strip 14, wherein a first portion 31a of the first edge 31 of the third strip 13 is not connected to the fourth strip 14, and wherein a second portion 31b of the first edge 31 of the third strip 13 is connected to the fourth strip 14.

In other words, the third strip 13 and the fourth strip 14 may only be partially connected to each other along the first edge 31 of the third strip 13, similar to the connection of the first strip 11 and the second strip 12 along the first edge 21 of the first strip 11. In particular, a first portion 31A of the first edge 31 of the third belt 13 is movable relative to the fourth belt 14, as best seen in fig. 1A. Thereby, good wearing comfort is achieved.

The second belt 12 is partially arranged between the third belt 13 and the fourth belt 14. In other words, the first belt 11, the second belt 12, the third belt 13, and the fourth belt 14 are arranged in a staggered manner. For example, second strap 12 may partially overlap third strap 13 and partially overlap fourth strap 14.

Exemplary upper 10 further includes fifth strap 15 and sixth strap 16, which are arranged similarly to first strap 11 and third strap 13 or second strap 12 and fourth strap 14, respectively.

The second belt 12 includes a first edge 41 that includes a first portion 41a and a second portion 41 b. The first portion 41a of the first edge 41 of the second strip 12 is not connected to the fifth strip 15 and the second portion 41b of the first edge 41 of the second strip 12 is connected to the fifth strip 15.

Fourth band 14 includes a first edge 51 that includes a first portion 51a and a second portion 51 b. First portion 51a of first edge 51 of fourth strap 14 is not connected to sixth strap 16 and second portion 51b of first edge 51 of fourth strap 14 is connected to sixth strap 16.

First, second and fifth straps 11, 12 and 15 are disposed on the medial side of upper 10, while third, fourth and sixth straps 13, 14 and 16 are disposed on the lateral side of upper 10. It is to be understood that upper 10 may include any number of straps greater than 1. It is also to be understood that the arrangement of the belts is not limited to that shown in fig. 1A to 1C. Specifically, the example upper 10 shown in fig. 1A-1C is an example upper for a left foot, but the upper 10 according to the present invention may equally be used for a right foot. The first belt 11, the second belt 12 and the fifth belt 15 do not necessarily need to be arranged on the inside. The first belt 11, the second belt 12 and the fifth belt 15 may alternatively be arranged on the outside. The first belt 11, the second belt 12 and the fifth belt 15 need not even be arranged on the same side (e.g., outside or inside). The same applies analogously to the third belt 13, the fourth belt 14 and the sixth belt 16. The third belt 13, the fourth belt 14 and the sixth belt 16 may alternatively be arranged on the inner side. The third belt 13, the fourth belt 14 and the sixth belt 16 need not even be arranged on the same side.

The first angle 20a formed between the first edge 21 of the first strip 11 and the first edge 31 of the third strip 13 is about 100 degrees. A second angle 20b is formed between first edge 41 of second strip 12 and first edge 51 of fourth strip 14, where second angle 20b is less than first angle 20 a. In this example, the second angle is about 45 degrees. The first angle 20a is disposed closer to the toe region 18 of the upper 10 than the second angle 20 b.

The strips partially overlap such that a first region R1 of the upper includes 6 layers of the strip and a second region R2 of the upper includes only 4 layers of the overlapping strip. Upper 10 further includes a third region R3 that includes only 2 layers of overlapping strips.

The first region R1 is disposed immediately adjacent to the metatarsal region, and the second region R2 is disposed closer to the heel region 17 than the first region R1. Third region R3 is disposed even closer to heel region 17 than second region R2.

Upper 10 further includes a retention strap RT, as shown in fig. 1C, wherein retention strap RT is disposed in a direction from a medial region to a lateral region of upper 10. In other words, the retention strap RT extends laterally along the foot. In this example, the retention strap RT is disposed on the medial side of the upper, as shown in fig. 1C. The retaining strap RT will contact the foot of the wearer when he/she is wearing the shoe.

The first, second, third, fourth, fifth and sixth belts 11, 12, 13, 14, 15 and 16 and the retention belt RT in this example comprise a woven textile comprising elastane and polyester fibers. The belt is thus elastic. It is also possible that the belt comprises different materials and/or is produced by different techniques, such as woven textiles or non-woven textiles, etc. In particular, only the sub-set of strips may be elastic, while others are not.

Upper 10 further includes a coating applied as film F that partially covers first strip 11, second strip 12, third strip 13, and fourth strip 14. The coating comprises polyurethane and applying the film F comprises applying heat and gentle pressure to soften or partially melt the film to create a bond with the first, second, third and fourth bands 11, 12, 13, 14.

The example upper 10 is lace-free. Upper 10 according to the present invention provides a desirable fit and better ball control.

Fig. 2 shows a representation of the straps of an exemplary upper 10 according to the present invention, which particularly shows the connection of the straps to each other.

Upper 10 includes first strip 11 and second strip 12, (a) wherein first strip 11 includes first edge 21, (b) wherein a first portion 21a of first edge 21 of first strip 11 is not connected to second strip 12, and (c) wherein a second portion 21b of first edge 21 of first strip 11 is connected to second strip 12.

First strap 11 is connected to first toe element 18a along second edge 22 and to second toe element 18b along third edge 23. The third edge 23 is substantially perpendicular to the first edge 21 and the second edge 22 is substantially parallel to the first edge 21. The first and second bands 11, 12 are connected to each other along second and third edges 22, 23 (the second and third edges 22, 23 are different from the first edge 21).

Upper 10 further comprises a third strip 13, which is partially arranged between first strip 11 and second strip 12. The first edge 21 of the first strap 11 is at least partially unconnected to the third strap 13. In this example, the first edge 21 of the first belt 11 is not connected to the third belt 13 except at the point P at the end of the first edge 21. Similarly, third band 13 is connected to first toe element 18a along second edge 22 and to second toe element 18b along third edge 23. The third belt 13 further comprises a first edge 31 comprising a first portion 31a and a second portion 31 b.

Upper 10 further includes a fourth strip 14. The first portion 31a of the first edge 31 of the third strip 13 is not connected to the fourth strip 14, while the second portion 31b of the first edge 31 of the third strip 13 is connected to the fourth strip 14.

The second belt 12 is partially arranged between the third belt 13 and the fourth belt 14. In other words, the first belt 11, the second belt 12, the third belt 13, and the fourth belt 14 are arranged in a staggered manner. In this example, the third belt 13 partially overlaps between the first belt 11 and the second belt 12. The second belt 12 partially overlaps in one region between the third belt 13 and the fourth belt 14 and partially overlaps in another region between the first belt 11 and the fourth belt 14.

Exemplary upper 10 further includes fifth and sixth straps 15 and 16, which are arranged similarly to the arrangement of first and third straps 11 and 13 or second and fourth straps 12 and 14, respectively. It is to be understood that upper 10 may include any number of straps greater than 1.

Fig. 3 shows how a tension differential may be applied to the straps of an exemplary upper 10 according to the present invention. Specifically, fig. 3 shows a portion of upper 10 that includes a first strap 11 connected to a first toe element 18a along a second edge 22 and connected to a second toe element 18b along a third edge 23.

The first belt 11 comprises a first edge 21 and a second edge 22 arranged opposite the first edge 21. The first strap 11 is attached to the first toe element 18a by sewing. Tension is applied to second edge 22 of first strap 11 before sewing to attach first strap 11 to first toe element 18 a. The tension is also applied before the second portion 21b of the first edge 21 of the first tape 11 is attached to the second tape 12 (not shown). In other words, first strap 11 is sewn to the toe element and other straps at the same time, and when upper 10 is not being worn, first strap 11 is under tension.

Applying tension to first belt 11 includes pulling first edge 21a first distance 65 and pulling second edge 22 a second distance 66. The first distance 65 is greater than the second distance 66 so the tension along the first edge 21 is greater than the tension along the second edge 22. The drawing is performed in the longitudinal direction of the first edge 21 and the second edge 22, respectively. Therefore, a tension difference is generated between the first edge 21 and the second edge 22. Such a tension difference can be advantageously used to create a three-dimensional shape. It should be noted that the tension applied and the distance drawn over the belt edges may be arbitrarily selected according to different needs.

Even if tension is applied to first strap 11 prior to sewing as described, first strap 11 retains elasticity in the finished upper. In this example, the elongation at break of the first tape is 100%, i.e. the first tape 11 may be elongated 100% in length before tearing/breaking. Pulling the first edge 21a first distance 65 increases the length of the first tape along the first edge 21 by, for example, 20%. The remaining capacity of the first tape 11 to stretch along the first edge 21 is, for example, 80% of the original, unstretched length. In other words, the first belt retains its elasticity while being pulled to the pre-stretched condition.

Fig. 4 shows an exemplary shoe 70 comprising an upper 10 according to the invention and a sole element 71 comprising a plurality of spikes.

Fig. 4 shows how collar opening 72 of exemplary upper 10 according to the present invention may be particularly elastic and thereby allow the foot to enter upper 10 particularly easily. Upper 10 also provides sufficient support for the foot so that the footwear may be worn without laces.

Fig. 5 shows an exemplary upper 10 according to the present invention in two dimensions.

Upper 10 includes first strip 11 and second strip 12, (a) wherein first strip 11 includes first edge 21, (b) wherein a first portion 21a of first edge 21 of first strip 11 is not connected to second strip 12, and (c) wherein a second portion 21b of first edge 21 of first strip 11 is connected to second strip 12 by stitching.

The first edge 21 of the first strip 11 further comprises a third portion 21c which is arranged adjacent to the second portion 21b, but not adjacent to the first portion 21a, wherein the third portion 21c of the first edge 21 of the first strip 11 is not connected to the second strip 12.

During the manufacturing and assembly of the shoe, the upper 10 shown in fig. 5 may be placed on a shoe last to attach the sole element 71 thereto and thereby produce a shoe including the upper 10.
