Ultra-light high-resilience shoe sole and preparation method thereof

Abstract

The invention provides an ultralight high-resilience shoe sole. The ultralight high-resilience shoe sole comprises an insole, an outsole and a connecting layer connected between the outsole and the insole. Anti-skid structures integrally formed with the outsole are evenly distributed on the outsole, the connecting layer comprises first springback bodies and second springback bodies, the first springback bodies are connected into a whole through a plurality of inflation balls, the second springback bodies are arranged at the heel position and folded into multiple layers, and the first springback bodies are connected to the two sides of the second springback bodies. The number of folding layers of the second rebound body is gradually increased from the side edge to the heel, the thickness of each folding layer is gradually increased from the outsole to the midsole, and the preparation method of the shoe sole comprises the steps that 1, the outsole is manufactured, 2, the middle layer is manufactured, and 3, the midsole is manufactured and a mold is closed. According to the shoe sole, high resilience force is provided through cooperation of the folded multi-layer second resilience bodies and the multiple inflation balls, and the anti-skid structure at the bottom of the shoe sole further has the anti-skid function.

Description

technical field [0001] The invention relates to the technical processing field of shoe soles, in particular to an ultra-light high-resilience shoe sole and a preparation method thereof. Background technique [0002] Sports shoe soles usually consist of outsoles and midsoles. The outsole refers to the layer structure that is in direct contact with the ground. It is usually made of natural rubber or artificial rubber and has the functions of anti-slip, wear-resistant and bending-resistant. The midsole generally refers to the structure between the insole and the outsole, which mainly plays the role of shock absorption or rebound. At present, the midsole is mainly made of thermoplastic elastomer materials such as ethylene vinyl acetate copolymer (EVA), styrene-based thermoplastic elastomer (SBS), ethylene octene block copolymer (OBC), and thermoplastic polyurethane (TPU). foam structure. [0003] The shock-absorbing performance of the sole means that when the foot is subjected...

AI Technical Summary

Problems solved by technology

However, the soles of sports shoes in the prior art often increase the resilience by setting springs on the soles, but the design of adding springs undoubtedly increases the weight of the soles, and the contact between the springs and the sole materials is easy to corrode the soles, and it is difficult to do so. Lightweight and high resilience
