Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a shoe sole with shock absorption function and its support plate. Background Technology

[0002] Running shoes have relatively high requirements for the support performance of the sole. The midsole materials used in traditional running shoes are usually organic foam materials such as EVA and TPU. These organic foam materials are prone to collapse and lose their elastic support as the number of times they are worn and the running distance increases. Carbon plates can effectively overcome the above problems, so their application in the sole is becoming more and more common.

[0003] However, the following problems exist when using carbon plates as support inside the sole in existing technologies: carbon plates have high rigidity and a small deformation range, rely on a pre-set mechanical structure, such as bifurcation, to provide rebound, and cannot respond to dynamic changes in the foot in real time. Furthermore, carbon plates inside the sole are prone to delamination and cracking after long-term bending, especially at bifurcation. Once cracking occurs at bifurcation, the rebound effect provided by the carbon plate is greatly reduced. Utility Model Content

Example 1

[0022] Please see Figure 1-2 This utility model provides a shoe sole technical solution with shock absorption function: a shoe sole with shock absorption function includes a lower midsole 2, a support plate 3, and an upper midsole 4. The lower midsole 2 and the upper midsole 4 are fixedly connected, and an installation groove is left between the lower midsole 2 and the upper midsole 4. The support plate 3 is installed in the installation groove between the lower midsole 2 and the upper midsole 4. The front end of the support plate 3 is provided with a forked plate 31 and is an integrated structure. Five bifurcated plates 31 are provided, and the length and width of the five bifurcated plates 31 gradually decrease from the inside to the outside. The bifurcated plate 31 has an arc-shaped structure, and the thickness of the five bifurcated plates 31 gradually decreases from the inside to the outside. In this implementation, the lower midsole 2 and the upper midsole 4 are connected by hot melt or glue; The forefoot area is divided into five independent bifurcated plates 31, corresponding to the distribution of the human metatarsophalangeal joint. The five independent bifurcated plates 31 reduce weight, provide efficient elasticity, and make the sole lighter. Furthermore, the arc-shaped structure and thickness distribution of the bifurcated plate 31 ensure that the five bifurcated plates 31 conform to the natural curvature of the metatarsophalangeal joint, improving the support effect on the arch of the foot. Thus, the support plate 3 and the bifurcated plate 31 can provide comprehensive support for the wearer's foot.
