ABSTRACT:
A footwear includes a sole having a rear socket, a middle transverse ventilation channel, and a plurality of front longitudinal ventilation channels fluidically communicated with a wearer's toe portions, an elastic pad having a plurality of longitudinal holes or elastic tubes formed in the rear socket of the sole, an upper cover covering the sole having a filter formed on a front toe portion of the upper cover, and an inner sole having a plurality of perforations in the front toe portion, so that the elastic pad may serve as a pump for sucking air from the wearer's toe portions, through the perforations of inner sole, the filter of upper cover and the longitudinal channels in the sole and for discharging the air through the transverse channel towards an environment, and the elastic pad may also serve as a shock absorber during sporting or jogging uses.
