Air permeable middle sole of a shoe

Abstract

An air permeable middle sole including a plastic layer and an air permeable woven layer covering up the plastic layer; multiple ventilation pores being consistently disposed in the plastic layer; and multiple grooves being molded among and connecting through those ventilation pore; a wall is disposed to the edge of the plastic layer; a blank edge surrounding pores being disposed on the bottom of the plastic layer to ensure tight adhesion to the insole; grooves being directly in the plastic layer; the woven layer being made of air permeable material to permit vertical air circulation through woven layer and pores; the grooves allowing unobstructed expelling of odor to ambient air; and grooves and pores permitting water containment and sweats built up on the shoe to be expelled in time.

1 . An air permeable middle sole including a plastic layer and an air permeable woven layer covering up the plastic layer; multiple ventilation pores being consistently disposed in the plastic layer; and multiple grooves being molded among and connecting through those ventilation pores. 
     
     
         2 . The air permeable middle sole as claimed in  claim 1 , wherein a blank edge surrounding the area where multiple ventilation pores are provided is provided on the plastic layer. 
     
     
         3 . The air permeable middle sole as claimed in  claim 1 , wherein those grooves include lateral ones and longitudinal ones with certain portion of those lateral grooves passing through the wall. 
     
     
         4 . The air permeable middle sole as claimed in  claim 1 , wherein those grooves are distributed in a reticular pattern.
