A multifunctional insole of the present invention is formed of non-slip bio soft silicon, maximally protects foot and knee joints distributing and buffering external impact due to embossing protrusions of various sizes and shapes, circulation air cushion and residual air cushion between through holes, and a Velcro bottom insole, has an effect of protecting frostbite, and has a structure capable of discharging air through an air discharge hole. The multifunctional insole according to the present invention comprises an intermediate arch unit outwardly bulging on the surface, and realizing multiple functions. In the intermediate arch unit, a circular arch protrusion formed on a silicon surface applies acupressure, and performs a sterilizing function by emitting ultraviolet LED at the same time. |
