ABSTRACT:
A shoe sole includes an insole having front vent holes; and an outsole comprising a heel comprising an open cavity, a first check valve extending from the cavity to the external, and a flexible protrusion on the heel bottom; a cover fitted on the cavity and comprising grooves and a second check valve communicating with the grooves and the cavity; front projections on the outsole top; and a channel on the arch top. Foot stepping will compress the protrusion to close the first check valve and open the second check valve such that air within the cavity is expelled to a sole of the foot via the second check valve, the grooves, the channel, and the vent holes. Foot lifting will return the protrusion to its original shape with the first check valve open and the second check valve closed so as to draw air into the cavity.
