Structure of shoe sole having superior ventilation function and double- landing function

Abstract

A shoe sole according to an aspect to the invention has ventilation function and has a double-landing function. The shoe sole includes a main groove, and sole including a pressure pad of a flat shape and connection portion. The main groove is formed on a bottom surface at a heel area and communicates with a ventilation groove supplying air into an inside of a shoe to supply the air into the inside of the shoe. The pressure pad convexly protrudes toward the ground at an area corresponding to the main groove. The connection portion connects the pressure pad and the sole. The shoe sole has a double-landing process. In the double-landing process, a bottom surface of the pressure pad is in contact with the ground and is introduced into the groove, and then, the bottom surface of the sole is in contact with the ground. The connection portion is thinner than the pressure pad so that the pressure pad is easily introduced when landing.

1 . A shoe sole, wherein the shoe sole having superior ventilation function and having a double-landing function, comprising:
 a mid-sole  100  comprising a main groove  110 , wherein the main groove  110  formed on a bottom surface at a heel area and communicating with a ventilation groove  120  supplying air into an inside of a shoe to supply the air into the inside of the shoe; and   a sole  200  comprising a pressure pad  210  of a flat shape and a connection portion  214 , wherein the pressure pad  210  convexly protruding toward the ground at an area corresponding to the main groove  110 , wherein the connection portion  214  connecting the pressure pad  210  and the sole  200 ;   wherein the shoe sole has a double-landing process,   wherein a bottom surface of the pressure pad  210  is in contact with the ground and is introduced into the groove  110 , and then, the bottom surface of the sole  200  is in contact with the ground in the double-landing process, and   wherein the connection portion  214  is thinner than the pressure pad  210  so that the pressure pad  210  is easily introduced when landing.   
     
     
         2 . The shoe sole according to  claim 1 , wherein the main groove  110  comprises a mid-sole protrusion  112  for supporting the pressure pad  210 , and
 Wherein the mid-sole protrusion  112  is contracted when the pressure pad  210  is introduced to absorb shock generated from the ground. 
 
     
     
         3 . The shoe sole according to  claim 2 , wherein the pressure pad  210  comprises a pad groove  212  where the mid-sole protrusion  112  is inserted, and
 wherein the pad groove  212  prevents distortion of the mid-sole protrusion  112  and enhances shock-absorption force. 
 
     
     
         4 . The shoe sole according to  claim 1 , wherein the mid-sole  100  comprises an auxiliary groove  140  formed at a bottom surface of an elbow area, and
 wherein the sole  200  comprises an auxiliary pad  220  formed at an area corresponding to the auxiliary groove  140 . 
 
     
     
         5 . The shoe sole according to  claim 1 , wherein the mid-sole  100  further comprises a flow path pipe  130  having a pipe shape and communicating with the main groove  110  and the ventilation groove  120 .
