Research Progress in the Design and Application of Functional Insoles
Functional insoles have specific corrective,therapeutic,and preventive effects,and are generally divided into prefabricated insoles and customized insoles.At present,materials used to make functional insoles on the market include ethylene vinyl acetate copolymer(EVA),thermoplastic polyurethanes(TPU),latex,leather,cork,and carbon fiber.Materials,structures,and production parameters are factors that directly affect the effectiveness of functional insoles and their wearing comfort.Although functional insoles have broad application prospects,their popularity in China is still relatively low.There is still a significant gap in the public's understanding of functional insoles compared to developed western countries.
