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.

1 . An air-ventilating shoe sole, comprising: 
 a shoe sole base;    an X-shaped ventilating groove on a top surface of said shoe sole base;    a plurality of transverse recesses on a portion of said top surface of said shoe sole base corresponding to a thenar portion and an arch portion of a foot;    a pair of main ventilating grooves crossing said transverse recesses to form an air passage net, rear ends of said main ventilating grooves being connected to a front end of said X-shaped ventilating groove; and    a flange vertically extending from a rear portion of said shoe sole base, an inner wall of said flange being provided with a pair of elongated air-circulating chambers, bottom ends of said air-circulating chambers being connected to a rear end of said X-shaped ventilating groove, said flange further including a pair of vent holes disposed in an upper portion thereof, said vent holes going through upper ends of said air-circulating chambers;    whereby warm and humid air inside a shoe said shoe sole is attached to and ambient air can exchange;    whereby positions of said vent holes can effectively prevent inward permeation of water; and    whereby said shoe sole will not influence the outlook and the comfort of the shoe.    
     
     
         2 . The air-ventilating shoe sole of  claim 1  wherein there is one air-circulating chambers.  
     
     
         3 . The air-ventilating shoe sole of claim I wherein there are two air-circulating chambers.  
     
     
         4 . An air-ventilating shoe sole, comprising: 
 a shoe sole base;    a main ventilating groove of shape selected from capital omega and cursive  1  on a top surface of said shoe sole base;    a plurality of transverse recesses on a portion of said of surface of said shoe sole base corresponding to the thenar portion and the arch portion of a foot; and    a pair of flanges respectively extending uprightly from two lateral sides of said shoe sole base, an inner wall of each of said flanges being provided with a plurality of elongated air-circulating chambers, a bottom end of each of said air-circulating chambers being connected to a leg of said main ventilating groove, a top end of each of said air-circulating chambers being provided with a vent hole.    
     
     
         5 . The air-ventilating shoe sole of  claim 1  further including an air-ventilating channel formed on said top surface of said shoe sole base, said air-ventilating channel having a front end connected to said main ventilating grooves and a rear end connected to said flange, said air-circulating chambers being two air passages formed through a U-shaped frame divided by a central vertical partition strip, said U-shaped frame enclosing a rear exit of said air-ventilating channel, a cover being attached to said flange so as to isolate said rear exit of said air-ventilating channel from outside, said two air passages respectively connecting said vent holes, thereby warm and humid air inside a shoe said shoe sole is attached to and ambient air can exchange.
