Modular Cycling Shoe and Sole Designed For The Same

Abstract

The invention is that of a removable shoe sole and a cycling shoe comprising said removable shoe sole, wherein the removable shoe sole may be affixed to the bottom of the cycling shoe to enable the wearer to gain traction on surfaces such as muddy ground surfaces. The removable shoe sole may be unitary or modular in design and comprises traction means such as anterior, medial and posterior traction means for enabling a cyclist to quickly affix the removable shoe sold to the bottom of his or her cycling shoes and walk or run across ground surfaces having low traction. The traction means may comprise ridges and valleys or similar means for engaging low-traction ground surfaces. The removable shoe sole may be made of durable material and affixed to a cycling shoe using off-the-shelf fasteners such as will be familiar to one of ordinary skill in the art.

What is claimed is: 
     
         1 . A removable shoe sole, the shoe sole comprising:
 an anterior portion having insertion points for affixing an anterior traction means thereto;   a medial portion having insertion points for affixing a medial traction means thereto;   a posterior portion having insertion points for affixing a posterior traction means thereto; and   a means for securing the removable shoe sole to the bottom of a cycling shoe.   
     
     
         2 . The removable shoe sole according to  claim 1 , wherein each of the insertion points for affixing the anterior, medial and posterior traction means thereto comprises a threaded collar corresponding to a threaded T-nut, wherein the T-nut is threaded into the collar to affix each traction means to the removable shoe sole. 
     
     
         3 . The removable shoe sole according to  claim 1 , wherein each of the insertion points for affixing the anterior, medial and posterior traction means thereto comprises a collar corresponding to a T-nut, wherein the T-nut is affixed to each traction means to the removable shoe sole by tension. 
     
     
         4 . The removable shoe sole of  claim 1 , wherein each traction means comprises a topography having ridges and valleys for engagement of a ground surface. 
     
     
         5 . A cycling shoe having a removable shoe sole according to  claim 1 . 
     
     
         6 . A cycling shoe having a removable shoe sole according to  claim 2 . 
     
     
         7 . A cycling shoe having a removable shoe sole according to  claim 3 . 
     
     
         8 . A cycling shoe having a removable shoe sole according to  claim 4 . 
     
     
         9 . A removable shoe sole according to  claim 1 , wherein the shoe sold is modular. 
     
     
         10 . A removable shoe sole according to  claim 1 , wherein the shoe sole is fabricated of material selected from the group consisting of carbon, thermoplastic, rubber, metal, fiberglass and graphite. 
     
     
         11 . The removable shoe sole according to  claim 1 , wherein each traction means is affixed at the insertion points using an engagement means selected from the group consisting of flat head cap screws, socket head cap screws, T-nuts, and M5 nuts. 
     
     
         12 . The removable shoe sole according to  claim 10 , wherein the material has coefficient of friction of at least 75 grams. 
     
     
         13 . The removable shoe sole according to  claim 12 , wherein the material has coefficient of friction of at least 80 grams. 
     
     
         14 . The removable shoe sole according to  claim 13 , wherein the material has coefficient of friction of at least 95 grams. 
     
     
         15 . The removable shoe sole according to  claim 14 , wherein the material has coefficient of friction of at least 100 grams. 
     
     
         16 . The removable shoe sole according to  claim 15 , wherein the material has coefficient of friction of at least 150 grams. 
     
     
         17 . The removable shoe sole according to  claim 16 , wherein the material has coefficient of friction of at least 200 grams. 
     
     
         18 . The removable shoe sole according to  claim 17 , wherein the material has coefficient of friction of at least 250 grams. 
     
     
         19 . The removable shoe sole according to  claim 18 , wherein the material has coefficient of friction of at least 300 grams. 
     
     
         20 . The removable shoe sole according to  claim 19 , wherein the material has coefficient of friction of at least 350 grams.
