TPU damping soles for heads and tail parts of functional shoes

Abstract

The invention discloses TPU (Thermo Plastic Urethane) damping soles for the heads and the tail parts of a pair of functional shoes, comprising EVA (Ethylene Vinyl Acetate) upper layers, TPU middle layers and bottom rubber layers, wherein the stressed parts of the TPU middle layers opposite to the forefeet and heels are projected towards to the directions of the EVA upper layers and in arc shapes along the length directions of the soles of the feet; and a hollow damping cavity is respectively arranged at the lower sides of the projected parts. The hollow damping cavities are designed according to the streamlines of the feet, so the in the cavities are in corresponding arc shapes, and the damping property can be automatically adjusted according to the different parts of the feet, the different exercise types and the different landing habits. The TPU damping soles for the heads and the tail parts of the functional shoes can buffer the pressure while the feet contact with the ground in any angles under stress to reach the damping effect and meet the needs of the various exercises; and the soles are rationally designed and easily processed, have the advantages of convenient use and durability, and save the resources.

Description

technical field [0001] The invention relates to sports shoe soles, in particular to a functional toe and tail TPU shock-absorbing shoe sole with simple production process, low cost, easy processing, and the ability to adjust the degree of shock absorption according to the stress on the feet. Background technique [0002] With the continuous development of the economy and society, people's material living standards continue to improve, and the demand for material enjoyment is getting more and more attention, especially the requirements for daily necessities are getting higher and higher. Shoes are an important part of people's basic necessities of life, and the function of the sole directly affects the comfort and fatigue of walking. In order to improve people's comfort and reduce fatigue during exercise, more and more shock-absorbing shoes have emerged as the times require. [0003] During sports, different parts of the same sole need to provide different shock absorption p...

AI Technical Summary

Problems solved by technology

[0006] Shock absorbing device shock absorption: It is necessary to install a shock absorber on the sole of the shoe. The structure of the shock absorber is more complicated, and the chamber corresponding to the matching sole also has a more complicated structure and cannot be adjusted as needed.

[0007] Shock absorbing rod shock absorption: Although it can meet the force requirements of different types of sports, the pro...
