Shoe outsole

Abstract

An outsole 1 comprises a high hardness portion 7 and a hardness portion 9. A hardness Ha of the high hardness portion 7 which is measured by a durometer of a type A is 75 to 100. A hardness Hb of the low hardness portion 9 which is measured by the durometer of the type A is equal to or more than and is less than 75. A value of (Ha/Hb) is 1.07 to 2.00. An area ratio of the high hardness portion 7 occupying a bottom e of the outsole 1 is 10% to 90%. An area ratio of the low dness portion 9 occupying the bottom face of the outsole 1 10% to 90%. The sum of the area ratio of the high hardness portion 7 and that of the low hardness portion 9 is 80% or more.

What is claimed is:  
     
         1 . An outsole comprising a high hardness portion in which a hardness measured by a durometer of a type A is 75 to 100 and a low hardness portion in which a hardness measured by the durometer of the type A is equal to or more than 50 and is less than 75, an average hardness of the high hardness portion being 1.07 to 2.00 times as high as that of the low hardness portion.  
     
     
         2 . The outsole according to  claim 1 , wherein the average hardness of the high hardness portion is 1.20 to 1.80 times as high as that of the low hardness portion.  
     
     
         3 . The outsole according to  claim 1 , wherein an area ratio of the high hardness portion occupying a bottom face is 10% to 90% and an area ratio of the low hardness portion occupying the bottom face is 10% to 90%.  
     
     
         4 . The outsole according to  claim 1 , wherein a sum of the area ratio of the high hardness portion occupying the bottom face and that of the low hardness portion occupying the bottom face is 80% or more.  
     
     
         5 . The outsole according to  claim 1 , wherein a protruded portion is present on the bottom face of the high hardness portion.  
     
     
         6 . The outsole according to  claim 1 , wherein the high hardness portion and the low hardness portion are arranged alternately in a longitudinal direction.  
     
     
         7 . The out sole according to  claim 1 , where in the high hardness portion is provided in two places or more and the low hardness portion is provided in two places or more.  
     
     
         8 . A shoe having an out sole comprising a high hardness portion in which a hardness measured by a durometer of a type A is 75 to 100 and a low hardness portion in which a hardness measured by the durometer of the type A is equal to or more than 50 and is less than 75, an average hardness of the high hardness portion being 1.07 to 2.00 times as high as that of the low hardness portion.
