ETPU Shoe Sole is an innovative material in the field of sports shoes. ETPU is a bead formed by supercritical foaming of thermoplastic polyurethane elastomer (TPU). It is also called popcorn midsole because it looks like popcorn. This material has excellent resilience, extremely low compression permanent deformation and good wearing experience. ETPU soles are not only light and durable, but also can effectively absorb and disperse impact force, providing excellent shock absorption effect for the wearer. In addition, ETPU materials are environmentally friendly and efficient, and there is no pollution during the processing process, which meets the modern people's pursuit of environmental protection and sustainable development. Therefore, ETPU soles have become a high-tech material that many sports brands are vying to adopt.
