         2 . The method of  claim 1  wherein the sole base material is a leather and the insert material is a polymer or a rubber. 
     
     
         3 . The method of  claim 1  wherein the coupling includes applying an adhesive. 
     
     
         4 . The method of  claim 1  wherein creating an insert is a molding. 
     
     
         5 . The method of  claim 1  wherein creating a shoe sole and creating a cavity are each performed in a single molding process. 
     
     
         6 . The method of  claim 1 , further comprising forming the plurality of anti-skid features on the bottom of the surface of the insert using a molding process. 
     
     
         7 . The method of  claim 1 , further comprising:
 forming a groove along at least a portion of the raised cavity wall between the top surface of the sole body and spaced apart from the bottom surface of the sole,   wherein creating an insert includes forming a protrusion about a portion of the periphery of the insert corresponding to a mating portion of the raised cavity wall having the groove formed therein, and   wherein coupling includes placing the protrusion of insert into the corresponding groove of the raised cavity wall.   
     
     
         8 . The method of  claim 7  wherein coupling includes applying an adhesive to at least one of the groove and the protrusion prior to the placing of the protrusion into the groove. 
     
     
         9 . The method of  claim 1  wherein the cavity has a predefined depth from an outer surface of the lower sole to a bottom cavity surface and wherein coupling the insert includes coupling the upper surface of the insert to the bottom cavity surface of the sole. 
     
     
         10 . The method of  claim 9 , further comprising:
 forming a groove along at least a portion of the raised cavity wall between the bottom surface of the cavity and spaced apart from the bottom surface of the sole,   wherein creating an insert includes forming a protrusion about a portion of the periphery of the insert corresponding to a mating portion of the raised cavity wall having the groove formed therein, and   wherein coupling includes placing the protrusion of insert into the corresponding groove of the raised cavity wall.   
     
     
         11 . The method of  claim 1  wherein the cavity is a through cavity extending between the bottom base surface and the upper base surface. 
     
     
         12 . The method of  claim 1 , further comprising:
 forming a heel main body having a proximal end defining an upper attachment portion, a heel distal end and a heel shank defined there between, the proximal end formed for attachment to a heel portion of a shoe sole base and having a wide dimension corresponding to an outer periphery thereof, the distal end formed to have an outer periphery with an outer dimension between about 0.9 and about 1.25 inches and the heel shank formed to have a narrowed neck portion with an outer dimension being comparatively less than the outer dimension of the distal end and between 0.25 and 0.40 inches.   
     
     
         13 . The method of  claim 12 , further comprising forming a surface contact portion coupled to the distal end, the surface contact portion being formed from a non-skid material. 
     
     
         14 . The method of  claim 12  wherein the distal end is formed to have a shape selected from the group consisting of a polygon, a regular convex polygon, an equiangular polygon, a star shape, flower shape, and rounded corner shapes thereof. 
     
     
         15 . The method of  claim 12  wherein the heel shank is formed to have a narrowed neck portion with an outer dimension is about 0.3 to about 0.36 inches and the distal end is about 1.0 inch. 
     
     
         16 . A method of making a women's high heel shoe comprising:
 providing a shoe sole base composed of leather defining a lower sole positioned at a front for supporting a ball and toes of a wearer of the high heel shoe, the base having an outer perimeter defining the shape of the upper sole and an exposed sidewall thereof, the sole being composed of a sole base material;   creating a cavity in the lower sole base having a shape that conforms to a shape of the lower sole, the cavity having a cavity perimeter that is set back from the outer perimeter defining the lower sole and defining an outsole there between, the cavity defining a raised cavity wall about a perimeter of the cavity;   creating an insert composed of a rubber or a polymer having an insert shape defined by a periphery that is substantially the same as the shape of the cavity, the insert having an outer edge, a top surface and a bottom surface, the bottom surface including one or more anti-skid features, the insert being composed of an insert material selected from a material having anti-skid characteristics and being different than the sole material;   inserting the insert into the cavity; and   coupling the insert to the base material after insertion in the cavity.   
       forming a heel main body having a proximal end defining an upper attachment portion, a heel distal end and a heel shank defined there between, the proximal end configured for attachment to the upper sole of the base and having a wide dimension corresponding to an outer periphery thereof, the distal end having an outer periphery with an outer dimension between about 0.9 and about 1.25 inches and the heel shank having a narrowed neck portion with an outer dimension being comparatively less than the outer dimension of the distal end and between 0.25 and 0.40 inches. 
     
     
         17 . The method of  claim 16 , further comprising forming a surface contact portion coupled to the distal end, the surface contact portion being formed from a non-skid material. 
     
     
         18 . The method of  claim 16  wherein the neck portion of the heel shank is formed to be substantially circular. 
     
     
         19 . The method of  claim 16  wherein the distal end is formed to have a shape selected from the group consisting of a polygon, a regular convex polygon, an equiangular polygon, a star shape, flower shape, and rounded corner shapes thereof. 
     
     
         20 . The method of  claim 16  wherein the heel shank is formed to have a narrowed neck portion with an outer dimension is about 0.3 to about 0.36 inches and the distal end is about 1.0 inch.
