Pronation correction

Abstract

Overpronation of a foot is limited and corrected by a footwear article that acts on a foot in motion to act in relation to foot stepping by use of vertical restraints to move the calcaneus bone in a medial direction and shift pressure of the stepping foot and pull the first metatarsal laterally and shifting pressure off the first medial side to its lateral side.

What is claimed is: 
     
         1 . A footwear system for compensation and correction of overpronation of a user's foot constructed and arranged to limit shifting of a user's calcaneus bone in any given step/impact of the foot and over the course of multiple usage to move the calcaneus position medially and elevate it and to move the weight-center of the foot laterally, thereby lessening the angle of pronation. 
     
     
         2 . The system of  claim 1  implemented by a footwear horizontal sole insert, with vertical extension tabs of the sole insert positioned adjacent and constructed in relation to foot stepping restraining movement at the first metatarsal and medial movement of the calcaneus bone all such restraint including forces through the sole insert portion. 
     
     
         3 . The system of  claim 2  wherein the horizontal sole insert restrains the foot by a medial first metatarsal vertical tab and a lateral vertical tab adjacent the calcaneus bone, the vertical tabs being extensions of and integral with the horizontal sole portion. 
     
     
         4 . The system of  claim 3  as implemented by a diagonal horizontal sole portion insert between a vertical tab at a medial side of a first metatarsal bone and a lateral vertical tab adjacent to the calcaneus bone and restraining movement thereof. 
     
     
         5 . The system of  claim 1  as implemented by an overlying pair of diagonal horizontal shoe insert portions,
 (a) one such portion with vertical extension tabs of the sole insert positioned adjacent and constructed in relation to foot stepping restraining movement at the first metatarsal and lateral movement of the calcaneus bone all such restrained including forces through sole insert portion; and 
 (b) one such portion wherein the sole insert the foot from a fifth metatarsal tab or a lateral tab adjacent the calcaneus bone. 
 
     
     
         6 . The article of  claim 5  and further comprising means for adjusting cross angle sole portions. 
     
     
         7 . The system of  claim 5  as implemented by overlaying two diagonal horizontal sole portions at a user's first metatarsal bone and calcaneus bone,
 (a) the sole portion with vertical tab extension at a user's first metatarsal bone and calcaneus bone, 
 (b) a second portion with vertical tab extensions at a user's fifth metatarsal and calcaneus bones. 
 
     
     
         8 . The article of  claim 7  further comprising means for adjusting cross angle of the sole portion.
