Insole with air permeation and shock damping funtion

The utility model relates to an insole, particularly the multi-layer insole with the functions of deodorization, moisture absorption, ventilation and shock absorption. The utility model aims at solving the problems of poor breathability and poor shock absorption character of the prior art. The insole comprises a moisture absorption layer 1 of a skin layer and a shock absorption layer 6 of a bottom layer. A micropore isolation layer with a smooth surface and a penetration layer 4 are orderly arranged below the moisture absorption layer. The shock absorption layer is arranged at a heel part, and the moisture absorption layer is the leather moisture absorption layer. The micropore isolation layer is provided with a micropore smooth skin layer 2 and a non-woven cotton fluffy layer 3. The penetration layer is the soft foaming penetration layer, and the shock absorption layer is the sponge shock absorption layer. Air holes are all arranged at the penetration layer and the shock absorption layer. The utility model is suitable for matching with various shoes. The desiccation of the interior of the shoes can be kept, and the cerebral part can be protected by the shock absorption function.
