Ventilated shoe sole

Abstract

A ventilated shoe sole is disclosed. This unique shoe sole is constructed with an elastic mid sole containing multiple cylindrical air spaces and multiple air vents arranged in parallel lines pattern across the sole, where the air vents communicates with their respective cylindrical air spaces underneath to allow air circulation around the bottom of the shoes. Therefore, heat and unpleasant foot odors can be rapidly expelled to the outside. In addition, the elastic mid sole provides an extra cushioning for the body weight. This shoe sole aids the design of comfortable and healthful footwear suitable for long time wearing.

1 . A ventilated shoe sole, comprising 
 an outer sole that is a bottom layer of the shoe sole;    a mid sole that is a supporting structure having a heel portion and having multiple air vents on top and multiple cylindrical air spaces in the middle thereof, disposed in parallel lines pattern widthwise, where the air vents communicates with their respective cylindrical air spaces underneath; and    an insole that is placed over the mid sole, the central part thereof having an open area to allow the air vents to be exposed.    
     
     
         2 . The shoe sole as claimed in  claim 1 , wherein the mid sole is constructed with a bevel edge on one end and progressively increases in thickness from the back of the toes to the heel.  
     
     
         3 . The shoe sole as claimed in  claim 1 , wherein the mid sole has multiple cylindrical air spaces disposed in parallel lines pattern widthwise and extending to two sidewalls with open ends.  
     
     
         4 . The shoe sole as claimed in  claim 3 , wherein the cylindrical air spaces are formed with diameters progressively increasing to correspond with the thickness of the sloping mid sole.  
     
     
         5 . The shoe sole as claimed in  claim 1 , wherein the mid sole is a bow shape having one large air pocket underneath.
