Abstract

Disclosed is a customized shoe sole having a multi-level cushion column, which can improve impact absorption and dispersion while walking. The customized shoe sole comprises at least one multi-level cushion column including a plurality of cushion layers piled vertically, wherein at least one of the cushion layers has an elastic hardness different from those of the other layers, so as to start to be elastically deformed under a specific load condition.

1 . A customized shoe sole having a multi-level cushion column comprising:
 at least one multi-level cushion column including a plurality of cushion layers piled vertically,   wherein at least one of the cushion layers has an elastic hardness different from those of the other layers, so as to start to be elastically deformed under a specific load condition.   
     
     
         2 . The customized shoe sole of  claim 1 , wherein one or more of the cushion columns are provided all over or partially to the shoe sole.

         4 . The customized shoe sole of  claim 3 , wherein the plurality of the cushion columns have a structure of the cushion layers, which is the same to or different from each other. 
     
     
         5 . The customized shoe sole of  claim 3 , wherein the plurality of the cushion columns have a structure of the cushion layers, the number of which is the same to or different from each other. 
     
     
         6 . The customized shoe sole of  claim 3 , wherein the neighboring cushion layers in the plurality of the cushion columns have a size the same to or different from each other. 
     
     
         7 . The customized shoe sole of  claim 3 , wherein the neighboring cushion layers in the plurality of the cushion columns, which are of the same level, are mutually connected by connecting ribs. 
     
     
         8 . The customized shoe sole of  claim 3 , wherein the adjacent cushion layers in the plurality of the cushion columns, which are made of the same material, are mutually connected by connecting ribs. 
     
     
         9 . The customized shoe sole of  claim 1 , wherein at least one of the cushion layers has a cross section of circle, oval, polygon, star or heart. 
     
     
         10 . The customized shoe sole of  claim 1 , wherein the cushion column includes,
 a first cushion layer, and   a second cushion layer piled on or beneath the first cushion layer,   wherein the first and the second cushion layers have an elastic hardness different from each other, to start to be elastically deformed under different load conditions respectively.   
     
     
         11 . The customized shoe sole of  claim 10 , wherein the cushion column further includes a third cushion layer piled on or beneath the second cushion layer, which has an elastic hardness different from that of the first or the second cushion layer. 
     
     
         12 . The customized shoe sole of  claim 1 , wherein one of a pile of the cushion layers has a receiving portion partially receiving another cushion layer which is vertically adjacent to the one. 
     
     
         13 . The customized shoe sole of  claim 1 , wherein a cushion chamber is formed in at least one of the cushion layers.
