Air-ventilating shoe sole

Abstract

An air-ventilating shoe sole has a plurality of connected passages on the top surface thereof for ventilating air. 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.

Description

FIELD OF THE INVENTION [0001] The present invention relates to air-ventilating shoes, more particularly to an air-ventilating shoe sole wherein the air-ventilating structure can effectively exchange cool, dry ambient air with the warm, humid inside the shoe it is attached to air. The air-ventilating shoe sole is integrally formed with the shoe sole, so that it will not influence the outlook and the comfort of the shoe it is attached to. BACKGROUND OF THE INVENTION [0002] Closed shoes of the prior art generally have the problem of air ventilation. The warm and humid air trapped within the shoes as they are worn is the main cause for athlete's foot. Therefore, shoemakers have developed various types of air-ventilating / circulating shoe soles to enhance the air circulation in a shoe and the sanitation of footwear. [0003] A common feature of the air-ventilating / circulating shoe soles of the prior art is air passage connecting the interior of a shoe with the ambient atmosphere so as to lo...

AI Technical Summary

Benefits of technology

[0004] Accordingly, the primary objective of the present invention is to provide an air-ventilating shoe sole can effectively prevent the water permeation problem.

Problems solved by technology

Closed shoes of the prior art generally have the problem of air ventilation.

Therefore, vent holes exposed on the outer surface of the shoe are inevitable, which constantly caused a consumer's doubt of water permeation problem.

Since the vent holes are usually disposed near the bottom of a shoe, the water permeation problem can indeed occur when persons wearing the shoes step into a water pit.
