With the subdivision of footwear materials, more and more attention is paid to the effect of sole functions on the overall footwear. The following is an introduction to the classification of various sole materials.

TPR: Thermoplastic Elastomer (Thermoplastic Elastomer), also known as Thermoplastic Rubber (Thermoplastic Rubber), is a combination of rubber and thermoplastic properties, showing high elasticity of rubber at room temperature, but high plasticity at high temperature Molecular materials are also the third generation of rubber after natural rubber and synthetic rubber, referred to as TPE or TPR. It has the characteristics of fast processing, high labor productivity and easy recycling.

EVA: Ethylene Vinyl Acetate, a light and elastic chemical synthetic substance. This kind of material is mainly combined with rubber or composed of soles at present. Its processing technology includes primary foaming (commonly used for outer midsoles) and secondary foaming molding soles (now MD midsoles). It has the characteristics of light weight, elasticity and good seismic performance.

RB: Mainly refers to natural rubber, synthetic rubber, etc. It is the main raw material for making sole materials. With wear-resistant, non-slip and other functions.

PU: Polyurethane synthetic material, divided into polyester type and polyether type. A durable material that is often used in the midsole of the sole of the shoe sole to cushion and shock. It is also used alone as a sole, mainly foamed PU is widely used, characterized by lighter rubber and wear resistance.

PVC: Polyvinyl chloride (polyvinyl Chloride), the natural color is yellowish translucent, shiny. This material can be processed by injection molding (shot) process, there are modified and non-modified points, the current domestic market is mainly used in the production of low-end shoes
