In addition, support bradyseism layer 3 through increasing in this application to carry out the bradyseism to supporting layer 2, avoid the fracture of supporting layer 2, can improve the shock attenuation effect of sole simultaneously, increase of service life.

In a specific embodiment, the upper layer 1 and the support cushioning layer 3 of the shoe midsole can be made of EVA, PU, TPU, TPE or nylon PEBAX polymer foam. In practice, the midsole top layer 1 may be the same material as the support cushioning layer 3 or a different material, and the same hardness may be used for the midsole top layer 1 and the support cushioning layer 3, or a different hardness may be used, i.e., the midsole top layer 1 may be softer or harder. The materials and the hardness of the upper layer 1 and the supporting cushioning layer 3 on the shoe insole can be set according to different requirements and are all within the protection range.

The supporting layer 2 disclosed in the application is of a 3D structure, and specifically, the shape of the supporting layer is similar to a spoon shape, namely, the front sole section and/or the rear heel section are inclined in the transverse direction and are cambered surfaces. In a specific embodiment, the forefoot segment is a region longitudinally extending from the corresponding toe with curvature to the front end of the arch, and the shape of the projected outline corresponds to the projected outline of the forefoot; the toe-bending device can be further divided into a corresponding toe area (part) and a corresponding metatarsal bone area, wherein the foremost end of the corresponding toe area is the foremost end of the rigid component, one side corresponding to the big toe is the inner side, and one side corresponding to the small toe is the outer side; the end corresponding to the metatarsal bone area corresponds to the front end of the arch of foot and has smaller width. The line of the front sole section corresponding to the foremost end of the toe part can be a straight line or a curve (comprising a circular arc line or a bending line which conforms to the outline of the toe). And the forefoot segment extends longitudinally in an arc, and the curvatures of its corresponding toe area and its corresponding metatarsal area may be identical or slightly different. The heel section extends and is connected with the front sole section from the corresponding heel, particularly longitudinally extends to the front end of the arch, and comprises a corresponding heel area (part) and a corresponding arch area; the rearmost end corresponding to the heel area is the rearmost end of the rigid part, and the corresponding arch area is the connecting part of the heel section and the half sole section.

In practice, the support layer 2 may be a carbon fiber member, a glass fiber member, or a nylon member, as long as it is a material with high rigidity and toughness. The specific thickness and material of the supporting layer 2 can be set according to different requirements and are within the protection range, and the shape of the supporting layer 2 can be optimally designed by combining human engineering. Preferably, the length of the supporting layer 2 is not shorter than 1/2 of the length of the sole, extending from the heel to the toe box.

In a preferred embodiment, the hardness of the large base layer 4 is 50-70 degrees (Shore A), and the density is not more than 1.5g/cm³The dry friction system is not less than 0.7, and the wet friction coefficient is not less than 0.5. The hardness of the upper layer 1 of the shoe insole can be 30-50 degrees (Shore C), and the material density is less than 0.2g/cm³. Those skilled in the art will appreciate that the specific hardness, density, etc. of the support cushioning layer 3 and the upper layer 1 of the midsole can be set according to different needs and within the protection scope.

In one embodiment, the forefoot and heel sections of the support cushioning layer 3 are provided in a separate configuration. In practice, the support cushioning layer 3 may also be a plurality of separate components to facilitate processing and to facilitate adjustment of thickness requirements.

Preferably, the difference between the thickness of the forefoot part and the height of the heel part of the sole is 5mm-20 mm. With the above structure, the height difference between the forefoot portion and the heel portion can be realized by supporting the height difference between the forefoot portion and the heel portion of the cushioning layer 3, or by combining the height difference between the supporting layer 2. The difference in height for the forefoot and heel parts can be achieved by the difference in thickness of the different parts.

Because different runners 'level is different, from amateur level to professional sportsman's level, their muscle ability is very different, and the drop is great, and is required differently to foot muscle level, consequently in order to satisfy different levels of runner and use, has set up three drop scheme in this application:

wherein, use the sole to contact ground completely as the benchmark, the difference of falling is 20mm around, and the height of preceding sole portion is greater than the height of heel: the requirement on foot muscles is highest, and the competition and training requirements of professional athletes are met; similarly, the front-back fall difference value is 15 mm: the requirement on foot muscles is moderate, and the requirements of competition and training of elite horizontal runners are met; and the difference between the front and rear is 10 mm: the requirement on foot muscles is low, and the requirements of wearing match and training of most amateur popular runners can be met. Namely, the height difference between the front part and the back part of the sole can have a certain range, and the larger the difference is, the higher the requirement on the muscle strength of the runner is.

Compared with the traditional running shoe sole, the shoe sole in the application belongs to a structure with a high front sole and a low rear heel; the thickness of the heel of the sole is smaller than that of the fore sole. The human body biomechanics characteristic of the front sole landing posture is as follows: the forefoot part firstly falls to the ground → quickly transits to the heel part (the heel is hardly stressed) → transits to the forefoot part and runs out by one step with the force of pedaling and stretching. The spoon-shaped structure with the high front part and the low back part of the sole in the application is more suitable for the human body biomechanics characteristic of the running mode that the front sole part falls on the ground, and can provide professional functional running shoes for people using the mode that the front sole falls on the ground to run.

On the basis of the technical scheme, the thickness of being close to the back heel section in the preceding sole section in this application is greater than the thickness that the back heel section was kept away from to preceding sole section to when the sole was normally placed to ground, the height that the height of one side that the back heel section was kept away from to preceding sole section was higher than the height of one side that is close to the back heel section, so made the toe end of sole perk upwards, in order to adapt to the change of human sole when running.

Similarly, the thickness of the heel section close to the front sole section is set to be larger than the thickness of the heel section far away from the front sole section. So, can reduce holistic weight when guaranteeing heel absorbing requirement. Taking the adult man 41 standard code as an example, the weight of a single shoe is 150g-300 g. It will be appreciated by those skilled in the art that the shape and size of the forefoot and heel sections can be configured to suit different needs and within the scope of protection.

On above-mentioned technical scheme's basis, 3 one side of the support bradyseism layer that disclose in this application bonds with big bottom 4, and the opposite side bonds with shoes insole upper strata 1 to foretell supporting layer 2 is embedded in and is supported between bradyseism layer 3 and the shoes insole upper strata 1, can bury deeply totally and embed, also can partially expose visible (side wall or bottom surface expose).

In addition, this application has still disclosed a running shoes, including the sole, wherein, this sole is the sole disclosed in the above-mentioned embodiment, consequently, the running shoes that have this sole also have above-mentioned all technological effects, no longer give unnecessary details here.
