Breathing Shoe

Abstract

A breathing shoe has a network of intercrossing and interconnecting pipes in the outer sole and midsole thereof. Each of the pipes has at least one outlet in communication with the environment in the front and rear position of the shoe. Each of the pipes is formed with several vent holes. Any hole of the outer sole has a semicircular hole opening upward. The midsole has a semicircular hole opening downward corresponding to the outer sole and a vent hole. After the outer sole and the midsole are combined together, the air chamber formed by the two semicircular holes along with the vent holes exchange humid and hot air inside the shoe with the fresh air outside, keeping the inside dry.

What is claimed is: 
     
         1 . A breathing shoe having a network of intercrossing and interconnecting pipes in the outer sole and the midsole thereof; wherein each of the pipes has at least one outlet to the ambient space in the front and rear positions of the shoe; each of the pipes is formed with a plurality of vent holes, any of which has a semicircular hole opening upward; the midsole has a semicircular hole opening downward corresponding to the outer sole and a vent hole; when the outer sole and the midsole are combined into one, the air chamber formed by the two semicircular holes and the vent holes exchange hot and humid air inside the shoe with fresh air outside, keeping the inside dry. 
     
     
         2 . The breathing shoe of  claim 1 , wherein the outlets of the pipes are closed with plugs. 
     
     
         3 . The breathing shoe of  claim 2 , wherein the plugs are disposed inside a plug saving holes near the outlets.
