[0043] In this embodiment, the second midsole 20 and the first midsole 10 can be made of EVA foam materials (ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer) is made by copolymerizing ethylene (E) and vinyl acetate (VA), and its English name is: Ethylene Vinyl Acetate, abbreviated as EVA) of different hardness. Preferably, the first midsole 10 is an EVA foam midsole, and the second midsole 20 is an ETPU foam midsole. Because the bottom surface of the first midsole 10 needs to directly contact the ground, the hardness of the first midsole 10 needs to be greater than or equal to 55C (Shore Hardness C), preferably 60C, to ensure the wear resistance of the wear-resistant sole. In addition, a wear-resistant pattern 110 is provided on the bottom surface of the first midsole 10, which not only improves the anti-slip performance, but also improves the wear resistance, and has good practicality. The hardness of the second midsole 20 can be relatively low, relatively soft, and can provide good elasticity and comfort of wearing.

[0044] Furthermore, a edging structure 104 is provided on the contour edge of the first midsole 10, i.e., a raised portion of the edge, which is bonded to the upper surface through the raised portion to achieve a covering and fixing effect, has good fit, and improves the stability of the shoe structure.

[0045] In this embodiment, a wear-resistant area 101 is arranged on the edge area of ​​the rear sole area of ​​the bottom surface of the first midsole 10, and the wear-resistant area 101 is integrally formed or spliced ​​with the first midsole 10, and a wear-resistant groove 102 is arranged on the front sole area of ​​the bottom of the first midsole 10; a carbon plate is arranged between the second midsole 20 and the first midsole 10, and the carbon plate is arranged between the heel and the arch of the shoe, and the outsole 30 is arranged on the wear-resistant groove 102.

[0046] The outsole 30 can be made of rubber material, or EVA foam material or TPU (thermoplastic polyurethane) material, and the hardness of the outsole 30 is greater than or equal to 55C, so that the outsole 30 has excellent wear resistance and environmental protection. The wear-resistant sole produced can achieve a wear resistance of 9.8g / cm^2 and a rebound performance of greater than or equal to 55Mpa, taking into account both comfort and wear resistance, that is, the wear-resistant sole has the advantages of good shock absorption, wear resistance and comfort.

[0047] Specifically, the outsole 30 is bonded to the bottom surface of the forefoot of the first midsole 10, and the second midsole 20 is bonded to the top surface. The first midsole 10 itself has good hardness, and combined with the structural strength of the carbon plate, it can provide good bending elasticity and form good wear resistance, while the second midsole 20 can provide good shock absorption and softness.

[0048] like Figure 3As shown, in this embodiment, the contour groove 103 is provided with a notch 1031 on the outside of the forefoot area, and the forefoot area of ​​the second midsole 20 is provided with an edge-wrapping protrusion 201 engaged with the notch 1031. It also includes an edge-wrapping sheet 50 provided on the outside of the edge-wrapping protrusion 201, the bottom of the edge-wrapping sheet 50 is provided between the outsole 30 and the first midsole 10, a plurality of fixing protrusions 202 are provided on the outer surface of the edge-wrapping protrusion 201, and a through hole 501 engaged with the fixing protrusion 202 is provided on the edge-wrapping sheet 50.

[0049] Specifically, the outer side edge of the forefoot area is formed by the second midsole 20 structure, and a complete edge edge is formed by filling. At the same time, the softness of the second midsole 20 can provide relatively soft comfort for the big toe and the side of the foot.

[0050] Furthermore, the edging piece 50 can be made of TPU material to reinforce the structure at that position, and at the same time cooperate with the connection of the first reinforcing piece 2031 to form a coating from the bottom to the side, thereby improving the strength of the structure; it not only meets the requirements of softness, but can also be coated on the shoe upper to provide connection and support effects, and has good structural strength.

[0051] like Figure 4 As shown, in this embodiment, a plurality of fixing protrusions 202 are arranged on the outer surface of the edge-wrapping protrusion 201, and a through hole 501 engaged with the fixing protrusion 202 is arranged on the edge-wrapping sheet 50. The fixing protrusion 202 can be a triangular protrusion, a rectangular protrusion, a circular protrusion, etc., or a self-designed heterogeneous protrusion. Through the cooperation of the fixing protrusion 202 and the through hole 501, the edge-wrapping sheet 50 is positioned and bonded, and structural support can be provided at the same time, and the stability of the structural cooperation can be improved, so that the edge-wrapping sheet 50 can provide more stable support.

[0052] like Figure 3 As shown, in this embodiment, a closed-loop groove 203 is provided in the forefoot area of ​​the second midsole 20 and close to the inner side of the wear-resistant sole, and an embedded first reinforcing plate 2031 is provided on the closed-loop groove 203; a circular texture area 301 is provided on the bottom surface of the outsole 30 and close to the inner side of the wear-resistant sole.

[0053] Specifically, the closed-loop groove 203 can be circular, and then a circular ring sheet (which can be an EVA foam sheet) of the same size is bonded in the closed-loop groove 203 to strengthen the structural strength of this part. In addition, the circular ring is close to the outer area of ​​the forefoot, which can provide support to prevent sprains. The texture area 301 can also be a circular area to provide better structural strength for the force-generating part of the forefoot, which has good practicality.

[0054] Furthermore, the first window 100 for observing the first reinforcing sheet 2031 is provided at the splicing line of the first midsole 10 and the outsole 30. By providing the first midsole 10 with a spliced ​​structure, the structure of the sole can be designed more flexibly, and different regions can be made of different materials to form different structural strengths in the regions; or the same material can be used to design a structure on the first midsole 10 to improve the corresponding structural performance, thereby reducing the overall weight of the sole and improving practicality.

[0055] like Figure 3 As shown, the first midsole 10 of the present embodiment is a semi-palm structure including an arch area and a rear sole area, the first midsole 10 is provided with an extension portion 109 on the inner side of the wear-resistant sole, the extension portion 109 is provided with a first splicing groove 1011, the inner side of the arch area of ​​the first midsole 10 is provided with a second splicing groove 1012 connected to the first splicing groove 1011, the outer side of the arch area of ​​the first midsole 10 is provided with a third splicing groove 1013 connected to the closed-loop groove 203; the first splicing groove 1011, the second splicing groove 1012 and the third splicing groove 1013 form a wear-resistant groove 102.

[0056] Specifically, the extension portion 109 extends from the arch to the toe area, and with the structure of the third splicing groove 1013, a larger bonding area can be provided, so that the first midsole 10 and the outsole 30 are bonded. At the same time, the middle parts of the first midsole 10 and the outsole 30 are both arc-shaped grooves, so that after bonding on both sides, a first window 100 can be formed in the middle to observe the inside of the sole, which has good aesthetics and also provides bending performance of the wear-resistant sole. The second splicing groove 1012 is integrally connected with the first splicing groove 1011 to increase the bonding area to the outsole 30, thereby improving the splicing strength of the structure.

[0057] like Figure 1 As shown, in this embodiment, a horseshoe-shaped second reinforcing sheet 105 is arranged on the side of the rear sole of the first midsole 10, and a third reinforcing sheet 106 is arranged on the outer side of the first midsole 10, and the third reinforcing sheet 106 is arranged between the forefoot area and the rear heel. The embedded and bonded second reinforcing sheet 105 (which can be an EVA foam sheet) on the side can provide structural strength in the heel area of ​​the shoe, so that the heel has good supporting strength and can prevent the heel from slipping off. The third reinforcing sheet 106 (which can be an EVA foam sheet) can provide a connection point for the connection between the wear-resistant sole and the shoe upper, and can also provide decoration to improve the beauty of the sole.

[0058] like Figure 2 and Figure 3As shown, in this embodiment, at least one second window 107 connected to the carbon plate is provided on the arch area of ​​the first midsole 10; and a third window 108 connected to the second midsole 20 is provided on the rear sole area of ​​the first midsole 10. The second window 107 is provided so that the carbon plate in the sole can be observed, and similarly, the third window 108 can be used to observe the second midsole 20 of the shoe, so that consumers can know the level and material of the wear-resistant sole. At the same time, the second window 107 is located in the arch area, which can provide a shock-absorbing and buffering effect, that is, the force transmitted to the human foot forms a collapse in the second window 107, thereby forming a buffer. The third window 108 can avoid the buffering of the force transmitted to the back heel of the human body, avoid direct force transmission, and form a collapse buffer in the third window 108.

[0059] Embodiment 2

[0060] like Figure 5 As shown, this embodiment provides a shoe, including the wear-resistant sole 1 described in the first embodiment, which can provide good wear resistance through the wear-resistant sole 1, and the shoe has good elasticity, which can provide users with good elastic performance. The flexibility of the second midsole 20 can provide excellent softness and improve the comfort of wearing. The overall weight design is light, which can provide users with better sports performance, reduce the burden of the shoes on the human body during long-term exercise, and has good practicality.
