[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] As described in the background section, while the cushioning layer in current shoe soles can effectively absorb impact, it inevitably leads to insufficient structural rigidity in the midfoot area, resulting in poor torsional resistance and weak arch support, which can easily cause foot fatigue and even injury. Furthermore, after prolonged use, the cushioning layer is prone to fatigue collapse, causing a rapid decline in cushioning performance and affecting the structural stability of the sole.

[0021] Based on this, this application provides a shock-absorbing shoe sole, which aims to solve the technical problem of poor cushioning and support performance of shoe soles in the prior art.

[0022] The embodiments of this application will be analyzed in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 4 The cushioning sole includes: an abrasion-resistant layer 1 in contact with the ground; a cushioning layer 2 disposed above the abrasion-resistant layer 1; a support layer 3 disposed between the abrasion-resistant layer 1 and the cushioning layer 2, and located in the heel area of ​​the cushioning layer 2; and a cushioning support plate 4 embedded in the midfoot area of ​​the cushioning layer 2, wherein the hardness of the cushioning support plate 4 is greater than that of the cushioning layer 2.

[0024] The cushioning layer 2 deforms in all directions under pressure. The cushioning support plate 4, with a higher stiffness than the cushioning layer 2, is embedded in the cushioning layer 2, providing support for the midfoot area. When the midfoot attempts to twist laterally due to uneven ground or body rotation, the cushioning support plate 4, with its higher stiffness, effectively resists this torsional deformation, greatly improving athletic stability and preventing excessive arch fatigue and sprains. Furthermore, the cushioning support plate 4 reduces the deformation of the cushioning layer 2 under complex stress, thereby mitigating the fatigue collapse of the cushioning layer 2 material. In more detail, the heel support layer 3 is primarily responsible for vertical impact stability, while the midfoot cushioning support plate 4 is primarily responsible for longitudinal support and torsional resistance; together, they construct a stable foot support system.

[0025] As a preferred embodiment, refer to Figure 3 The shock-absorbing support plate 4 is long and narrow, and the length direction of the shock-absorbing support plate 4 is consistent with the length direction of the shock-absorbing layer 2.

[0026] Among them, the shock-absorbing support plate 4 can provide continuous and uniform support along the arch of the foot, which not only effectively prevents the midfoot from bending and twisting during exercise, but also improves torsional stability.

[0027] As a preferred embodiment, the shock-absorbing support plate 4 is made of nylon material.

[0028] Among them, nylon material has high hardness, strong support and good toughness. Using nylon material can ensure the integrity of the shape and function of the shock-absorbing support plate 4 under long-term repeated stress, and prevent the performance failure caused by wall fracture.

[0029] In a preferred embodiment, the top surface of the damping layer 2 is provided with a groove structure (not shown in the figure), and the damping support plate 4 is fixedly connected to the groove structure by injection molding or pressing.

[0030] The use of injection molding or pressing processes ensures a strong bond between the shock-absorbing support plate 4 and the shock-absorbing layer 2, effectively preventing the shock-absorbing support plate 4 from shifting or loosening on the shock-absorbing layer 2 and ensuring the long-term stability of the anti-torsion function of the shock-absorbing support plate 4.

[0031] In summary, this cushioning sole provides an internal framework for the cushioning layer by embedding a high-rigidity cushioning support plate in the midfoot area of ​​the cushioning layer. This slows down the fatigue collapse of the cushioning layer material. Furthermore, the cushioning support plate works synergistically with the heel support layer, the upper and lower cushioning layers, and the abrasion-resistant layer, thus significantly enhancing the midfoot's torsional rigidity and arch support, effectively preventing sports injuries. While ensuring a cushioned feel, it also improves the overall stability and durability of the sole structure.

[0032] In a preferred embodiment, the bottom surface of the damping layer 2 is recessed inward to form a buffer space 20, which is located below the groove structure.

[0033] The buffer space 20 creates a pre-defined deformation area for the cushioning layer 2 below the shock-absorbing support plate 4. When the foot presses down, the cushioning layer 2 in this area can deform more significantly into the buffer space 20, enhancing the local cushioning effect without sacrificing the overall support stability of the midfoot.

[0034] In a preferred embodiment, the shock-absorbing layer 2 is made of foamed material.

[0035] Among them, foamed materials have good compressibility, which can efficiently absorb and disperse the impact force from the ground, thus achieving the function of shock absorption.

[0036] In a preferred embodiment, the shock-absorbing layer 2 has a plurality of vent holes 21 and vent grooves 22.

[0037] The design incorporates ventilation holes 21 and ventilation grooves 22 to create an air circulation channel in the sole, effectively expelling hot and humid air from the shoe cavity and improving dryness and comfort.

[0038] As a preferred embodiment, the support layer 3 adopts an air cushion rebound structure or a TPU support structure.

[0039] Among them, the air cushion rebound structure can absorb impact and generate upward rebound force through the compression and recovery of the sealed gas inside, thus improving the dynamic cushioning effect; the TPU support structure can provide support for heel landing with its toughness, effectively preventing heel rollover.

[0040] In a preferred embodiment, both the shock-absorbing layer 2 and the wear-resistant layer 1 are fixedly connected to the support layer 3 by adhesive bonding.

[0041] Among them, the adhesive fixing method achieves a stable and integrated connection between the shock-absorbing layer 2, the support layer 3 and the wear-resistant layer 1 through large-area surface contact.

[0042] As a preferred embodiment, refer to Figure 4 The bottom surface of the wear-resistant layer 1 is provided with an anti-slip groove 10.

[0043] Among them, the anti-slip groove 10 increases the friction of the ground surface and slows down wear through the division of the groove, thus comprehensively improving the durability of the sole.
