Shoe Sole with Torque Relief Component

Abstract

A shoe sole includes a tread section having a cavity, and a torque relief component disposed in the cavity. A fixed part of the torque relief component is secured in the cavity, and a rotating part of the torque relief component is rotatable relative to the fixed part via a magnetic force.

1 . A shoe sole comprising:
 a tread section having a cavity; and   a torque relief component disposed in the cavity, wherein a fixed part of the torque relief component is secured in the cavity, and wherein a rotating part of the torque relief component is rotatable relative to the fixed part, the rotating part being cooperatively engaged with the fixed part via a magnetic force.   
     
     
         2 . A shoe sole according to  claim 1 , further comprising a sole part secured to the rotating part. 
     
     
         3 . A shoe sole according to  claim 2 , wherein the sole part is raised relative to the tread section. 
     
     
         4 . A shoe sole according to  claim 3 , wherein the sole part comprises a tread, and wherein the sole part tread is formed of a different compound than the tread section. 
     
     
         5 . A shoe sole according to  claim 1 , wherein the tread section comprises a ball part in an area adjacent a location where a ball of a wearer's foot would lie, and wherein the cavity and the torque relief component are positioned adjacent the ball part of the tread section 
     
     
         6 . A shoe sole according to  claim 1 , wherein the tread section comprises at least one slot adjacent the cavity. 
     
     
         7 . A shoe sole according to  claim 6 , wherein the at least one slot is downward sloping. 
     
     
         8 . A shoe sole according to  claim 1 , wherein the fixed part is adhesively bonded in the cavity. 
     
     
         9 . A shoe sole according to  claim 1 , wherein the fixed part comprises an upper plate fixed to the shoe sole, and wherein the rotating part comprises a lower plate cooperatively engageable with the upper plate via the magnetic force and rotatable relative to the upper plate. 
     
     
         10 . A shoe sole according to  claim 9 , wherein the rotating part further comprises a sleeve, and wherein the lower plate is disposed in the sleeve. 
     
     
         11 . A shoe sole according to  claim 10 , wherein the sleeve is a low friction sleeve. 
     
     
         12 . A shoe sole according to  claim 9 , wherein at least one of the upper and lower plates contains a permanent magnet. 
     
     
         13 . A shoe sole according to  claim 12 , wherein the permanent magnet is embedded in a low friction material. 
     
     
         14 . A shoe sole according to  claim 1 , wherein the magnetic force is adjustable. 
     
     
         15 . A shoe sole comprising:
 a tread section having a cavity; and   a torque relief component disposed in the cavity, wherein a fixed part of the torque relief component is secured in the cavity, and wherein a rotating part of the torque relief component is rotatable relative to the fixed part via a magnetic force.   
     
     
         16 . A shoe sole according to  claim 15 , wherein the rotating part of the torque relief component is engageable with the fixed part via the magnetic force. 
     
     
         17 . A shoe sole according to  claim 15 , wherein the fixed part comprises an upper plate fixed to the shoe sole, and wherein the rotating part comprises a lower plate that is rotatable relative to the upper plate, the upper and lower plates comprising permanent magnets disposed with similar poles in facing relation, wherein the lower plate is secured adjacent the upper plate via a connector.
