Heel Suspend Footbed With Pronation Adapting Mechanism

Abstract

A thin footbed having incorporated spring structure that can adapt to a person's gait to avoid injuries and has minimal heel center pressure for prolonged comfort. The spring structure is made a carbon fiber and textile fabric hybrid material for high energy absorption capacity to prevent injuries from hard surface impacts.

         8 . The athletic shoe of  claim 2 , wherein said second spring plate has a thickness ranging from 0.5-5 mm. 
     
     
         9 . The athletic shoe of  claim 1 , wherein said first spring plate comprises another layer of textile fabrics, the carbon fiber sheet being molded between the two lays of textile fabrics. 
     
     
         10 . The athletic shoe of  claim 2 , wherein said second spring plate comprises another layer of textile fabrics, the carbon fiber sheet being molded between the two lays of textile fabrics. 
     
     
         11 . A footbed for use with an athletic shoe, configured for adapting to pronation that provides direct contact with a plantar surface of the foot of the user, comprising:
 an upper contact piece having textural polymer property for comfort feel of the plantar surface, said upper contact piece having a front portion and a heel portion that matches the user's foot shape, said heel portion having a left section, a center section and right section; and   a first spring plate being arch-shaped longitudinally along the front portion and the heel portion of the footbed, said first spring plate having a center section, a front end and a rear end;   wherein said first spring plate's center section is mounted underside of the left section of the heel portion of the upper contact piece, the front end and the rear end of the first spring plate being aligned longitudinally from the front portion to the heel portion of the upper contact piece;   wherein said first spring plate comprises at least a layer of carbon fiber sheet and a layer of textile fabrics being molded together.   
     
     
         12 . The footbed of  claim 11 , wherein said footbed configured for adapting to pronation that provides direct contact with a plantar surface of the foot of the user, further comprising:
