The utility model discloses a breathable insole with preceding intermediate layer that compresses after, including compression intermediate layer and air guide intermediate layer, the compression intermediate layer is including setting up before the shoe -pad respectively, before the rear foot, after compress the intermediate layer, the air guide intermediate layer is provided with air conduction channel and ventilative aperture, no matter this shoe -pad is full sole when using, preceding sole or rear foot exert pressure to the shoe -pad, the compression intermediate layer of pressurized can both be by at utmost compression work, help shoe -pad ventilative the taking a breath of taking the initiative, when rear foot compresses the intermediate layer after to and exerts pressure, preceding sole is less to the relative pressure of shoe -pad front end, that is it is less to the ventilative aperture oppression of shoe -pad front end, be favorable to the air to flow from the ventilative aperture of shoe -pad front end, current sole is favorable to the air to flow from the ventilative aperture in the rear end of shoe -pad when exerting pressure to preceding compression intermediate layer too, the interbedded compression performance utilization efficiency of compression of this shoe -pad is high, its excellent performance that takes a breath of while, the present invention has good practicality.
