[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] like Figures 1 to 3 As shown, this utility model provides a shoe sole structure, which includes an outsole 1, a midsole 2, and a support component 3. The midsole 2 is disposed on the outsole 1 and includes a forefoot section 21 and a heel section 22 disposed along the length direction. The midsole 2 is made of a resilient material. The support component 3 includes a cushioning layer 32 and a rebound layer 31. The rebound layer 31 is disposed between the outsole 1 and the forefoot section 21, and the cushioning layer 32 is disposed on the side of the heel section 22 opposite to the outsole 1. In this embodiment, since the midsole 2 is made of a rebound material and a rebound layer 31 is provided between the forefoot section 21 of the midsole 2 and the outsole 1, the sole structure has a good rebound effect, providing the user with sufficient rebound feedback, reducing the user's physical exertion and improving athletic performance. Since a cushioning layer 32 is provided on the heel section 22 of the midsole 2, the cushioning layer 32 can absorb the impact force when the user lands through elastic deformation, thereby reducing the impact damage to joints such as the ankle and knee, and improving comfort. The rebound layer 31 and the cushioning layer 32 are respectively provided for the forefoot section 21 and the heel section 22, and the two work together: the heel absorbs shock when landing and the forefoot rebounds when pushing off, which conforms to the foot landing method and ergonomic design, further improving the user's comfort when running. In addition, since the midsole 2 is located on the outsole 1, the outsole 1 can protect the midsole 2 and the support component 3, reducing the wear of the midsole 2 and the support component 3 during wear, thereby extending the service life of the sole structure.

[0038] In this embodiment, the rebound layer 31 is made of ethylene vinyl acetate copolymer (EVA), which is commonly used in the art. The rebound layer 31 has excellent rebound performance and a rebound rate of 65%. The outsole 1 is made of VIBRAM Litebase rubber, which can reduce the weight of the outsole 1 and increase the grip of the outsole 1. The midsole 2 is made of EVA material containing 40% polyether block amide (PEBAX), which has the advantages of lightweight, high rebound and strong durability. The cushioning layer 32 is made of artificial cartilage material (ACF). Artificial cartilage material is a biomimetic metamaterial composed of a polymer soft matrix and a micro-nano-scale porous structure. The cushioning layer 32 made of artificial cartilage material has an energy absorption efficiency of over 90% and excellent fatigue resistance, which can effectively absorb the impact of the pressure generated by the foot landing on the joint.

[0039] Furthermore, such as Figure 4 and Figure 5 As shown, the sole structure also includes a first reinforcing block 4 and a second reinforcing block 5, which are respectively disposed on the surfaces of the midsole 2 on both sides along its length. The first reinforcing block 4 and the second reinforcing block 5 enhance the protection and support for both sides of the foot, preventing displacement of the foot inside the shoe during exercise, and effectively suppressing shoe deformation, thereby greatly improving the protection of the user's feet. In this embodiment, both the first reinforcing block 4 and the second reinforcing block 5 are made of high-hardness EVA material.

[0040] like Figure 4 and Figure 5 As shown, the midsole 2 also includes an arch section 23, which is connected between the forefoot section 21 and the heel section 22. The first reinforcement block 4 is fixedly connected to the arch section 23, and the second reinforcement block 5 is fixedly connected to the heel section 22. The first reinforcement block 4 and the second reinforcement block 5 work together to improve the protection and support for the user's arch and heel when facing complex terrain.

[0041] Specifically, such as Figure 1 As shown, the support component 3 also includes a TPU support layer 33, which is disposed between the rebound layer 31 and the forefoot section 21. The TPU support layer 33 is made of thermoplastic polyurethane elastomer commonly used in the art, and has the characteristics of high strength, high toughness, and wear resistance. Both the TPU support layer 33 and the rebound layer 31 are disposed between the outsole 1 and the midsole 2, and the TPU support layer 33 and the rebound layer 31 cooperate with each other to provide the user with sufficient rebound force while also providing the user with stable support. In this embodiment, both the TPU support layer 33 and the rebound layer 31 are fan-shaped to match the shape of the forefoot.

[0042] To further improve user comfort and avoid discomfort to the feet caused by the protrusions of the TPU support layer 33 and the rebound layer 31, such as Figure 1 As shown, the midsole 2 has a first mounting groove on the side facing the outsole 1 that matches the TPU support layer 33 and the rebound layer 31. The TPU support layer 33 and the rebound layer 31 are fixedly installed in the first mounting groove. Since the depth of the first mounting groove and the sum of the thickness of the TPU support layer 33 and the rebound layer 31 are the same, the midsole 2 can be smoothly bonded to the outsole 1, thereby reducing foot discomfort.

[0043] like Figure 1 As shown, the midsole 2 has a second mounting groove on the side opposite to the outsole 1 that matches the cushioning layer 32. The cushioning layer 32 is fixedly mounted in the second mounting groove. Since the depth of the second mounting groove and the thickness of the cushioning layer 32 are the same, the side of the midsole 2 facing the foot can fit flat against the sole of the foot, further reducing foot discomfort.

[0044] like Figure 1 and Figure 2 As shown, the midsole 2 has a cushioning hole 24. The cushioning hole 24 increases the deformation space of the midsole 2 material and improves the cushioning stroke of the midsole 2, which can better absorb and disperse the impact force generated by the user during running.

[0045] like Figure 3 As shown, the outsole 1 has a gripping surface and an adhesive surface. The adhesive surface is bonded to the midsole 2. Anti-slip protrusions 11 are provided on the gripping surface. The anti-slip protrusions 11 greatly enhance the anti-slip ability of the outsole 1, making the outsole 1 suitable for wet and slippery roads and rugged mountainous terrain.

[0046] This embodiment also provides a running shoe, which includes an upper and the aforementioned sole structure, with the upper fixedly disposed on the midsole 2; in this embodiment, the running shoe can provide the user with sufficient cushioning and rebound, greatly improving the user's comfort when running.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
