When people wear sports shoes for exercise, the intersection area of the sole and the arch needs to withstand high-frequency repeated stretching, which makes this area of the sole prone to aging and cracking.

[0007] By adopting the above technical solution, a tensile metal wire is arranged at the intersection area of the sole part and the arch part of the sole body; when the sole body is bent and deformed, the tensile metal wire and the material at the bottom of the sole body jointly bear the tensile force; thereby reducing the tensile force on the bottom material of the sole body, slowing down the aging of the bending area of the sole body, and reducing the occurrence of cracks at the bottom of the sole body.
[0008] Optionally, along the length direction of the tensile metal wire, the tensile metal wire is provided with a plurality of metal nodes at intervals.
[0009] By adopting the above technical solution, a number of metal nodes are arranged on the metal wire so that the metal nodes and the sole body are engaged with each other; thereby improving the synergistic effect between the metal wire and the sole body material, so as to give full play to the tensile properties of the tensile metal wire and reduce the tensile force on the bottom material of the sole body.
[0010] Optionally, the distances between adjacent metal nodes increase gradually from the middle to both ends of the tensile metal wire.
[0011] By adopting the above technical solution, the metal node density in the middle area of the tensile metal wire is relatively large, which can increase the tensile force that the middle area of the tensile metal wire can withstand.

[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] The present application embodiment discloses a stretch-resistant sports shoe. Figures 1 to 3 The anti-stretch sports shoe comprises a sole body 1, an upper body 2 and a plurality of anti-stretch metal wires 3. The upper body 2 is arranged above the sole body 1, and the anti-stretch metal wires 3 are buried in the sole body 1.
[0034] Reference Figure 1 and Figure 2 The sole body 1 includes a toe portion 11, a sole portion 12, an arch portion 13, a heel portion 14 and a tail portion 15 from the toe to the heel. When people walk in sports shoes, the arch of the wearer's foot will bend around the sole, so that the intersection area of the sole portion 12 and the arch portion 13 of the sole will also bend and deform accordingly.
[0035] Reference Figure 2 and Figure 3 The sole body 1 is also provided with a plurality of drainage grooves 4, which are arranged at intervals at the intersection of the sole portion 12 and the arch portion 13; the plurality of drainage grooves 4 facilitate drainage of the sole body 1; on the other hand, by arranging the drainage grooves 4 in the bending deformation area of the sole body 1, it is also beneficial to the bending of the sole body 1.
[0036] Reference Figure 2 and Figure 3 When the sole of the sports shoe bends and deforms, there is a layer of material on the sole that is not subjected to tension and pressure, and the length of this layer of material remains unchanged; in material mechanics, this layer of material is defined as the neutral layer 6; the sole below the neutral layer 6 is the tension area, and the sole above the neutral layer 6 is the tension area; the farther the sole body 1 material is from the neutral layer 6, the greater the tension and pressure the material is subjected to.
[0037] The bottom material of the sole body 1 is farthest from the neutral layer 6 ; thus, the bottom material of the sole body 1 is subjected to a greater stretching effect, so that aging, cracks, etc. may occur.
[0038] In order to improve the tensile resistance of the bottom of the sole body 1, the tensile wire 3 is buried in the sole body 1 in this embodiment; and the tensile wire 3 is arranged on the side of the sole body 1 away from the upper body 2, one end of the tensile wire 3 is buried in the sole part 12, and the other end of the tensile wire is buried in the arch part 13. Therefore, when the sole body 1 is bent and deformed, the tensile wire 3 and the material at the bottom of the sole body 1 bear the tensile force together. This can reduce the tensile force on the bottom material of the sole body 1, slow down the aging of the bending area of the sole body 1, and reduce the cracks at the bottom of the sole body 1. The tensile wire 3 can be made of iron, copper or other alloy materials, so that the wire has good tensile resistance.
[0039] In order to improve the synergistic effect between the tensile metal wire 3 and the material of the sole body 1, the tensile metal wire 3 is also provided with a fixing section 32 and a metal section 31. The fixing sections 32 are provided at both ends of the tensile metal wire 3, and the metal section 31 is provided between the two fixing sections 32; and along the length direction of the tensile metal wire 3, a plurality of metal sections 31 are provided at intervals. By providing a plurality of metal sections 31 and fixing sections 32 on the metal wire, the metal sections 31 and the sole body 1 are engaged with each other; thereby improving the synergistic effect between the metal wire and the material of the sole body 1, so as to give full play to the tensile performance of the tensile metal wire 3 and share the tensile force on the bottom material of the sole body 1. The metal section 31 and the fixing section 32 can be formed by tying the tensile metal wire 3; or they can be formed by casting and stretching together with the tensile metal wire 3.
[0040] Reference Figure 3 In this embodiment, the volume of the fixing section 32 is larger than that of the metal section 31, thereby improving the effect of the fixing section 32 and the sole body 1 material interlocking with each other to fix the positions of the two ends of the tensile metal wire 3; reducing the tensile metal wire 3 being subjected to non-uniform tension, causing the metal wire and the sole body 1 to slide relative to each other.
[0041] Reference Figure 3 In this embodiment, the distance between adjacent metal nodes 31 increases from the middle to the two ends of the tensile wire 3. When the sole body 1 is bent and deformed, the tensile effect on the bottom of the sole body 1 decreases from the middle to the two ends. The density of the metal nodes 31 in the middle area of the tensile wire 3 is relatively large, which can increase the tensile force borne by the middle area of the tensile wire 3 and reduce the tensile effect of the sole body 1.
[0042] Reference Figure 4 In this embodiment, a plurality of tensile metal wires 3 are provided, and the plurality of tensile metal wires 3 are arranged at intervals along the inner side to the outer side of the sole body 1. That is, by providing a plurality of tensile metal wires 3, the tensile force at the bottom of the sole body is shared, and the tensile resistance of the sole body 1 is improved.
[0043] When people walk, most of the feet will bend inwards, so that the inner side of the sole body 1 is subjected to a greater pulling force.
[0044] Reference Figure 4 , the spacing between adjacent metal wires decreases from the inner side to the outer side of the upper body 2. That is, denser tensile metal wires 3 are arranged in the inner side of the sole body 1 to share the tensile effect on the bottom of the sole body 1.
[0045] Example 2
[0046] The difference between this embodiment 2 and embodiment 1 is that:
[0047] Reference Figure 5The upper body 2 further comprises a plurality of cavities 5 arranged at intervals, and the plurality of cavities 5 are arranged on the side of the tensile wire 3 close to the upper body 2. By arranging a plurality of cavities 5 on the opposite side of the tensile wire 3, the effective height of the sole body 1 in the area is reduced, and the distance from the bottom of the sole body 1 to the neutral layer 6 is reduced. Therefore, when the sole body 1 is bent and deformed, the tensile effect on the bottom surface of the sole body 1 can be reduced.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
