Shoe sole having rotatable discs

Abstract

Presently provided are a rotatable disc and a shoe sole. The rotatable disc is configured to be attached to the shoe sole. The shoe sole has at least two of rotatable discs in the shoe sole, wherein each of the rotatable discs are configured and disposed to independently rotate 360° about the shoe sole.

1 . A shoe comprising:
 a shoe sole having a hind foot or heel portion, a midfoot or arch portion, and a forefoot or toe portion;   at least two rotatable discs disposed on the shoe sole;   wherein each of the at least two rotatable discs are positioned on the shoe sole to provide engagement of the rotatable discs with a ground surface, or other surface, at selected instances of a physical activity.   
     
     
         2 . The shoe of  claim 1 , wherein each of the at least two rotatable discs are configured to spin 360° about its central axis. 
     
     
         3 . The shoe of  claim 2 , wherein each of the at least two rotatable discs are configured to spin in a clockwise and in a counter clockwise direction. 
     
     
         4 . The shoe of  claim 2 , wherein each of the at least two rotatable discs are configured to spin in only a clockwise direction or in only in a counter-clockwise direction. 
     
     
         5 . The shoe of  claim 1 , wherein each of the at least two rotatable discs have a tension tighten mechanism configured and disposed to adjust the ease of spinning of the rotatable discs. 
     
     
         6 . The shoe of  claim 5 , wherein the tension tighten mechanism has a fastener extending through a central vertical axis of the rotatable disc, the fastener being configured to tighten the rotatable disc to the shoe sole and increase a resistance to rotation of the rotatable disc. 
     
     
         7 . The shoe of  claim 1  having at least two of the rotatable discs disposed on the forefoot or toe portion of the shoe sole. 
     
     
         8 . The shoe of  claim 1  having at least three of the rotatable discs disposed on the shoe sole. 
     
     
         9 . The shoe of  claim 1 , wherein each of the rotatable discs has a base configured and disposed to hold the rotatable disc to the shoe sole. 
     
     
         10 . The shoe of  claim 4 , wherein each of the rotatable discs has a base configured and disposed to hold the rotatable disc to the shoe sole, the base and the rotatable have mating surfaces configured to stop a rotation of the disc in the clockwise or in the counter clockwise direction. 
     
     
         11 . The shoe of  claim 1 , wherein each of the rotatable discs has treads or cleats disposed to cooperate with the ground surface, or the other surface, at the selected instances of the physical activity. 
     
     
         12 . The shoe of  claim 1  comprising a pair of shoes with a right shoe and a left shoe, both shoes having the at least two rotatable discs disposed on its shoe sole. 
     
     
         13 . The shoe of  claim 8  having at least two of the rotatable discs disposed on the forefoot or toe portion of the shoe sole and at least one of the rotatable discs disposed on the heel portion of the shoe sole. 
     
     
         14 . A rotatable disc configured to be attached to a shoe sole comprising:
 a base configured to attach and hold a rotatable portion of the rotatable disc to the shoe sole;   the base and the rotatable portion having mating surfaces configured and disposed to provide for a desired rotation of the rotatable portion on the base;   a fastener extending through a central vertical axis of the rotatable disc, rotatably fastening the rotatable portion to the base;   the fastener being configured to tighten the rotatable disc to the shoe sole and increase a resistance to rotation of the rotatable portion.   
     
     
         15 . The rotatable disc of  claim 14  configured to spin 360° about its central axis. 
     
     
         16 . The rotatable disc of  claim 14  configured to spin in a clockwise and in a counter clockwise direction. 
     
     
         17 . The rotatable disc of  claim 14  configured to spin in only a clockwise direction or in only in a counter-clockwise direction. 
     
     
         18 . The rotatable disc of  claim 14  having treads or cleats disposed on the rotatable portion and configured to cooperate with the ground surface, or the other surface, at the selected instances of the physical activity. 
     
     
         19 . The rotatable disc of  claim 14 , wherein the rotatable portion is configured to be removed from the base. 
     
     
         20 . The rotatable disc of  claim 14 , wherein the base is configured to be removed from the shoe sole.
