Sole with elastic and vented buffer tubes

Abstract

A sole having high elasticity for a cushion-type shoe is provided. A plurality of elastic and vented buffer tubes are arranged on a top of the sole to be slightly raised from the sole and thereby form a wave-shaped top surface for the sole to massage a wearer's foot when the wearer walks. A duct having an inner part in the form of a communicating pipe for connecting to open ends of the buffer tubes and an outer part directed toward an outside of the sole. When the buffer tubes are compressed and squeezed, air in the buffer tubes are discharged via the duct; and when the buffer tubes are released from any pressure, they automatically recover from the compressed state and air outside the sole is sucked into the buffer tubes via the duct. Therefore, the buffer tubes provide the sole not only with good buffer and shock absorption ability but also excellent elasticity and bounce.

What is claimed is:  
     
         1 . A sole with elastic and vented buffer tubes, comprising: 
 a sole;    a plurality of hollow buffer tubes made of an elastic material and being parallelly arranged on a top of said sole, and each of said buffer tubes being provided at an upper part with a plurality of vent holes; and    a duct having an inner part in the form of a communicating pipe for connecting to open ends of said buffer tubes, and an outer part directed toward a peripheral edge of said sole to end at an outside of said sole.    
     
     
         2 . The sole as claimed in  claim 1 , wherein said buffer tubes are lengthwise arranged side by side on said sole.  
     
     
         3 . The sole as claimed in  claim 1 , wherein said buffer tubes are transversely arranged on said sole at predetermined intervals.  
     
     
         4 . The sole as claimed in  claim 1 , wherein said buffer tubes are directly associated with said sole.  
     
     
         5 . The sole as claimed in  claim 1 , wherein said buffer tubes are associated with an insole removably disposed above said sole.
