The air passages are connected to a plurality of vertically elongated air chambers on a flange extending from the rear side of the shoe sole, thereby forming a plurality of L-shaped air-ventilating structures. The upper ends of the air chambers are respectively provided with vent holes for exchanging cool air outside with the warm and humid air inside. The positions of the vent holes effectively prevent inward permeation of water. The air-ventilating structure is integrally formed within the shoe sole that it does not influence the outlook and the comfort of the shoe.
