Golf shoe with traction elements

Abstract

A golf shoe with an upper and a sole assembly comprising a midsole and an outsole with a plurality of traction elements arranged on the outsole. The plurality of traction elements includes a first set of traction elements provided along an anterior end and a posterior end of the outsole, a second set of traction elements provided along a lateral side edge and a medial side edge of the outsole, and one or more rubber inserts provided along the anterior and posterior ends of the outsole, wherein the one or more rubber inserts have a lower modulus of elasticity than the first set of traction elements and/or the second set of traction elements.

What is claimed is:

         2 . The golf shoe of  claim 1 , wherein the plurality of traction elements are configured to provide a first traction stiffness ranging from about 60 N/mm to about 80 N/mm in a medial-lateral direction on the ground surface. 
     
     
         3 . The golf shoe of  claim 2 , wherein the plurality of traction elements are configured to provide a second traction stiffness ranging from about 80 N/mm to about 120 N/mm in an antero-posterior direction on the ground surface. 
     
     
         4 . The golf shoe of  claim 1 , further comprising one or more particles embedded in or dispersed through the first material or the second material to enhance an abrasion resistance of the traction elements and a frictional engagement between the plurality of traction elements and the ground surface. 
     
     
         5 . The golf shoe of  claim 1 , wherein a first subset of the first set of traction elements or the second set of traction elements comprises the first feature, and wherein a second subset of the first set of traction elements or the second set of traction elements comprises the second feature. 
     
     
         6 . The golf shoe of  claim 5 , wherein the first subset of traction elements has a greater height or aspect ratio than the second subset of traction elements. 
     
     
         7 . The golf shoe of  claim 5 , wherein each and every traction element of the first subset of traction elements has a greater height than each and every traction element of the second subset of traction elements. 
     
     
         8 . The golf shoe of  claim 1 , wherein the first material has a higher density than the second material. 
     
     
         9 . The golf shoe of  claim 1 , wherein the first material has a greater hardness or modulus of elasticity than the second material. 
     
     
         10 . The golf shoe of  claim 1 , wherein a coefficient of friction between the second material and the ground surface is greater than a coefficient of friction between the first material and the ground surface. 
     
     
         11 . The golf shoe of  claim 1 , wherein the one or more rubber inserts are separated or spaced apart from the first set of traction elements and the second set of traction elements. 
     
     
         12 . The golf shoe of  claim 1 , wherein the one or more rubber inserts are positioned between the first set of traction elements and the anterior or posterior end of the outsole. 
     
     
         13 . The golf shoe of  claim 1 , wherein the one or more rubber inserts comprise a different material than the first set of traction elements and the second set of traction elements. 
     
     
         14 . The golf shoe of  claim 1 , wherein the traction elements in the first set of traction elements and the traction elements in the second set of traction elements comprise a thermoplastic polyurethane material with a higher modulus of elasticity than the one or more rubber inserts. 
     
     
         15 . The golf shoe of  claim 1 , wherein the second set of traction elements comprises a plurality of traction elements that gradually increase in length as the traction elements extend from the anterior or posterior ends of the outsole towards a midfoot region of the outsole. 
     
     
         16 . The golf shoe of  claim 1 , wherein the plurality of traction elements are positioned around a central region of the outsole. 
     
     
         17 . The golf shoe of  claim 1 , wherein the second set of traction elements comprises one or more fin shaped traction elements or one or more traction elements with a fanged profile. 
     
     
         18 . The golf shoe of  claim 1 , wherein the traction elements in the second set of traction elements each comprise a first surface extending vertically downwards from a base surface of the outsole and a second surface angled back towards the base surface of the outsole to form a pointed edge configured to penetrate the ground surface. 
     
     
         19 . The golf shoe of  claim 18 , wherein the first surface is configured to provide a first horizontal contact area ratio and a first vertical contact area ratio when the golf shoe is worn on the ground surface. 
     
     
         20 .
