What kind of shoe soles are wear-resistant?


Polyurethane shoe soles in plastics are wear-resistant and very lightweight, making them one of the best sole materials today.
In recent years, with the continuous improvement of daily living standards, people have been exposed to more and more styles and functions of footwear, among which the changes brought by sole materials are the foundation of the functional changes in footwear. The changes in the sole and upper structure require various materials or a reasonable combination of individual materials to achieve the best functionality, comfort, hygiene, and safety requirements of footwear.
The development of sole materials is inseparable from the development of petrochemicals and the rubber and plastics industry. From the most common pure rubber soles, PVC soles, SBS soles, etc., to the now popular polyurethane microporous soles, EVA secondary foamed midsoles, PU soles, TPR soles, and so on, the research and application of materials reflect the high level of global technological development.
Today, with the segmentation of footwear, sole materials are increasingly emphasizing the impact of sole functions on the overall footwear. Below is an introduction to the classification of various sole materials.
TPR sole: Thermoplastic elastomer, also known as thermoplastic rubber, is a polymer material that combines the characteristics of rubber and thermoplastic plastic, showing high elasticity at room temperature and can be molded at high temperatures. It is the third generation of rubber after natural rubber and synthetic rubber, abbreviated as TPE or TPR. It features fast processing, high labor productivity, and easy recyclability.
EVA sole: Ethylene-vinyl acetate copolymer, a lightweight and elastic chemical synthetic material. This material is mainly combined with rubber or used alone to form soles. Its processing technology includes primary foaming (commonly used for outer midsoles) and secondary foaming molded soles (current MD midsoles). It is characterized by being lightweight, elastic, and having good shock resistance.
RB sole: Mainly refers to natural rubber, synthetic rubber, etc., which are the main raw materials for making sole materials. It has functions such as wear resistance and slip resistance.
PU sole: Polyurethane synthetic material, divided into polyester type and polyether type. It is often used as a durable material for the midsole layer of the shoe's heel, providing cushioning and shock absorption. It can also be used alone as a sole, mainly in the form of foamed PU, which is lighter and more wear-resistant than rubber.
PVC sole: Polyvinyl chloride, which is naturally a light yellow translucent material with gloss. This material can be processed into soles through injection molding, with modified and unmodified types. Currently, it is mainly used in the production of low-end shoes in the domestic market.

The key to a good pair of shoes lies in the sole.

When choosing shoes, the first thing everyone looks at is the appearance of the shoes. The overall look and color combination of a pair of shoes are what attract people's attention.

What are the different structures of rubber shoe soles?

Rubber soles are divided into natural rubber and synthetic rubber based on the material.
