Description

Technical Field

[0001] This utility model relates to the field of shoe technology, specifically to an anti-torsion shoe sole. Background Technology

[0002] Existing shoe soles, especially those for athletic shoes, generally consist of a midsole and an outsole. The midsole typically uses a relatively soft material (such as EVA) to ensure the sole's elasticity, cushioning performance, and soft comfort.

[0003] When the foot typically lands, the heel of the shoe strikes the ground first, then transitions forward to the forefoot. Since the heel bears most of the pressure when it strikes first, an overly soft midsole will not provide sufficient support for the foot, resulting in relatively poor support performance. Furthermore, if the angle between the heel and the sole is unreasonable, such as the outer side of the heel striking the ground first, and the midsole is too soft, excessive deformation of the outer heel can cause the inner side of the heel to lift excessively and roll outward, increasing the risk of ankle sprains and twists. This also indicates relatively poor torsional rigidity.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0005] The purpose of this invention is to provide a torsion-resistant shoe sole with relatively good support performance and relatively good torsional resistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An anti-torsion sole includes an outsole and a midsole bonded to the outsole. The midsole is a forefoot portion corresponding to the forefoot, an arch portion corresponding to the arch of the foot, and a heel portion corresponding to the heel. A strip-shaped groove is formed at the bottom of the arch portion, extending along the width of the midsole and passing through both sides of the midsole. An anti-torsion plate, matching the groove, is attached to the bottom of the strip-shaped groove. The anti-torsion plate has a higher hardness than the midsole. A vertically arranged support plate is integrally connected to the rear end of the outer side of the anti-torsion plate. The end of the support plate away from the anti-torsion plate extends rearward to the rear side of the midsole corresponding to the heel. An embedding groove is formed on the outer side of the heel portion, and the support plate is embedded in the embedding groove.

[0007] As an improvement of this utility model, the anti-torsion plate is provided with a plurality of spaced protrusions on the side away from the arch of the foot. Each of the protrusions is arranged at an angle from one end relatively close to the inner side of the shoe midsole to the other end towards the rear side away from the shoe midsole.

[0008] As an improvement of this utility model, the outsole includes a first hoof plate located at the bottom of the forefoot and a second hoof plate located at the bottom of the heel. The first hoof plate and the second hoof plate have the same hardness, and the hardness of the second hoof plate is greater than that of the midsole. The rear end of the first hoof plate has a first bifurcated opening groove that extends vertically through the first hoof plate and extends to a position on the first hoof plate corresponding to the center of the forefoot. The front end of the second hoof plate has a second bifurcated opening groove that extends vertically through the second hoof plate and extends to a position on the second hoof plate corresponding to the center of the heel.

[0009] As an improvement of this utility model, the bottom of the shoe midsole is provided with a first groove corresponding to the first bifurcation opening groove, and the bottom of the shoe midsole is provided with a second groove corresponding to the second bifurcation opening groove. The first groove and the second groove are respectively connected to the strip groove.

[0010] As an improvement of this utility model, the first hoof has a plurality of first strip holes arranged around the first bifurcation opening groove, and the second hoof has a plurality of second strip holes arranged around the second bifurcation opening groove.

[0011] As an improvement of this utility model, the bottom of both the first hoof plate and the second hoof plate are provided with anti-slip patterns.

[0012] As an improvement of this utility model, the anti-torsion sheet is a TPU anti-torsion sheet.

[0013] As an improvement of this utility model, the outsole is a rubber outsole.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects: By attaching an anti-torsion plate to the bottom of the arch, stable support is provided for the arch, resulting in relatively good anti-torsion performance. At the same time, a support plate integrally connected to the anti-torsion plate wraps and supports the outer side of the midsole at the position corresponding to the support plate, reducing the risk of the foot rolling outward when the outer side of the midsole strikes the ground first due to excessive deformation. This provides relatively good support performance. Attached Figure Description

Detailed Implementation

[0017] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The terms "first," "second," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0019] like Figures 1-3 As shown, this embodiment provides an anti-torsion sole, including an outsole 10 and a midsole 20 composited on the outsole 10. Specifically, the outsole 10 is a rubber outsole, the midsole 20 is the forefoot part corresponding to the position of the forefoot of the human foot, the midsole 20 is the arch part corresponding to the position of the arch of the human foot, and the midsole 20 is the heel part corresponding to the position of the heel of the human foot.

[0020] For ease of description, the vertical direction of the sole is described as when the sole is placed normally on a horizontal surface. The side of the soles of the two shoes in the same pair facing each other is the inner side of the shoe, and the corresponding side is the outer side of the shoe. The side facing the toe is the front side, and the corresponding side is the back side.

[0021] A strip-shaped groove (not shown in the figure) is provided at the bottom of the arch area, extending along the width direction of the midsole 20. The strip-shaped groove extends through both sides of the midsole 20. A torsion plate 30 matching the strip-shaped groove is embedded at the bottom of the groove. The torsion plate 30 has a higher hardness than the midsole 20. In this embodiment, the torsion plate 30 is a TPU torsion plate. A vertically arranged support plate 31 is integrally connected to the rear end of the outer side of the torsion plate 30. It should be noted that the support plate 31 is approximately vertically arranged, meaning that the support plate 31... Vertical errors are permissible. The end of the support piece 31 away from the anti-torsion piece 30 extends backward to the position of the midsole 20 corresponding to the back of the human heel. An inlay groove is provided on the outer side of the heel, and the support piece 31 is inlaid in the inlay groove. By embedding the anti-torsion piece 30 at the bottom of the arch, stable support is provided for the arch, and the anti-torsion performance is relatively good. At the same time, the support piece 32, which is integrally connected to the anti-torsion piece 30, wraps and supports the outer side of the midsole 20 at the position corresponding to the upper part of the support piece 32, reducing the risk of the foot rolling outward when the outer side of the midsole 20 strikes the ground first. The support performance is relatively good.

[0022] The anti-torsion plate 30 has multiple spaced protrusions 32 on the side of the upper surface away from the midsole 20. Each protrusion 32 is arranged at an angle from one end relatively close to the inner side of the shoe midsole 20 to the other end towards the rear side away from the midsole 20. The protrusions 32 can increase the overall rigidity and toughness of the anti-torsion plate 30. At the same time, the gap between two adjacent protrusions 32 can support the arch of the foot and resist torsion. That is, when the arch of the foot is about to twist forward and backward, the gap between the protrusions 32 gradually decreases until they squeeze each other to generate a counterforce, effectively improving the anti-torsion and support performance.

[0023] The outsole 10 includes a first hoof plate 40 located at the bottom of the forefoot and a second hoof plate 41 located at the bottom of the heel. The first hoof plate 40 has the same hardness as the second hoof plate 41, but the second hoof plate 41 has a harder hardness than the midsole 20. The rear end of the first hoof plate 40 has a first bifurcated opening groove 42 that extends vertically through the first hoof plate 40 and reaches a position on the first hoof plate 40 corresponding to the center of the forefoot. This design makes the first hoof plate 41 horseshoe-shaped, which not only helps to reduce the weight of the first hoof plate 40 but also improves the stability of the outsole 10. The front end of the second hoof plate 41 has a second bifurcated opening groove 43 that extends vertically through the second hoof plate 41 and reaches a position on the second hoof plate 41 corresponding to the center of the heel. This design makes the second hoof plate 42 horseshoe-shaped, which not only helps to reduce the weight of the second hoof plate 41 but also improves the stability of the outsole 10.

[0024] Preferably, the bottom of the shoe midsole 20 is provided with a first groove corresponding to the first bifurcation opening groove 42, and the bottom of the shoe midsole 20 is provided with a second groove corresponding to the second bifurcation opening groove 43. The first groove and the second groove are respectively connected to the strip groove. This arrangement helps to reduce the weight of the shoe midsole 20 and also enhances the appearance of the sole.

[0025] Preferably, the first shoe plate 40 has a plurality of first strip holes 44 arranged around the first bifurcation opening groove 42, and the second shoe plate 41 has a plurality of second strip holes 45 arranged around the second bifurcation opening groove 43. This arrangement not only helps to reduce the weight of the outsole 10, but also enhances the wear resistance of the shoe outsole 10.

[0026] The bottom of both the first hoof plate 40 and the second hoof plate 41 are provided with anti-slip patterns (not shown in the figure). By providing anti-slip patterns, the anti-slip performance of the outsole 10 is improved.
