EVA (ethylene-vinyl acetate * * *): EVA is a lightweight material with excellent shock absorption, elasticity and wear resistance. It is also a common material for midsole, which is usually used for low-end sports shoes. But it is light in weight and may collapse after long-term use.
Silica gel: The elasticity of silica gel is acceptable, but it is relatively heavy and does not have perspiration function. Among the original materials of sports shoes, silicone materials are rare.
ORTHOLITE: This material has the characteristics of light weight, good shock absorption effect, durability and strong perspiration, and is especially suitable for use after long-term exercise. ORTHOLITE insoles are mainly used in jogging shoes and out shoes, especially shoes of brands such as Arthur and Mizuno.
Rubber: Rubber is a commonly used sole material with high wear resistance and slip resistance. It is also widely used to make soles for different purposes and occasions, such as out shoes, hard soles for sports shoes and soft soles for leisure shoes. However, the rubber sole is heavy, which is not conducive to long-term walking.
TPU (thermoplastic polyurethane): TPU is a kind of high-quality sole material with high elasticity and wear resistance, which can make the sole more durable, improve the fit between insole and sole, and is beneficial to sports performance. However, due to its high quality, the price of TPU material is relatively high.
PU: PU is a light and elastic sole material, which is softer and more comfortable than EVA and rubber. Compared with TPU, the toughness of PU is a little worse, but after modification, the surface pattern can be obtained, which makes the sole more beautiful.
