Specification


Memory insoles are also called slow rebound insoles; also known as memory foam (Memory Foam), which is a polyurethane polymer with an open-cell structure. The material has a special viscoelasticity Characteristics, reflecting the characteristics of a very soft material, and has a strong impact energy absorption capacity. This material molecule is very sensitive to temperature, so it is also called temperature-sensitive memory foam. Fortune rose insoles made of memory foam are called memory insoles.
