Insole

Abstract

An insole is described having a deep heel cup, and high medial and lateral flanges extending from said heel cup, wherein said heel cup cups the calcaneous of a foot in approximately a neutral degree of varus so that the insole does not induce locking of the midtarsal joint, and said high medial and lateral flanges extend continuously high along the medial and lateral sides of the insole substantially to the first and fifth metatarsal necks of the foot. The insole is useful for individuals with a high arch or supinated foot type.

What is claimed is:  
     
         1 . An insole comprising a deep heel cup, and high medial and lateral flanges extending from said heel cup, wherein said heel cup cups the calcaneous of a foot in approximately a neutral degree of varus so that the insole does not induce locking of the midtarsal joint, and said high medial and lateral flanges extend continuously high along the medial and lateral sides of the insole substantially to the first and fifth metatarsal necks of the foot.  
     
     
         2 . An insole as claimed in    claim 1    having from 1 to 5 layers.  
     
     
         3 . The insole as claimed in    claim 1    having a recess in the bottom surface of the heel cup.  
     
     
         4 . The insole of    claim 3    wherein said recess is occupied with a shock absorbing insert.  
     
     
         5 . The insole of    claim 4    wherein said shock absorbing material is made of polyurethane, solid rubber, microcellular rubber, resin rubber, polyvinyl chloride, ethyl vinylacetate, polyethylene or combinations thereof.  
     
     
         6 . The insole of    claim 1    made from polyurethane, polyurea, solid rubber, microcellular rubber, resin rubber, polyvinyl chloride, ethyl vinylacetate, polyethylene or combinations thereof.  
     
     
         7 . Method for treating an individual having a supinated foot type, comprising: supplying to said individuals an insole comprising a deep heel cup, and high medial and lateral flanges extending from said heel cup, wherein said heel cup cups the calcaneous of a foot in approximately a neutral degree of varus so that the insole does not induce locking of the midtarsal joint, and said high medial and lateral flanges extend continuously high along the medial and lateral sides of the insole substantially to the first and fifth metatarsal necks of the foot; and having such individual wear said insole.  
     
     
         8 . The method as claimed in    claim 7    wherein the insole has from 1 to 5 layers.  
     
     
         9 . The method as claimed in    claim 7    wherein the insole has a recess in the bottom surface of the heel cup.  
     
     
         10 . The method as claimed in    claim 9    wherein the recess of said insole is occupied with a shock absorbing insert.  
     
     
         11 . The method as claimed in    claim 10    said shock absorbing insert is made of polyurethane, solid rubber, microcellular rubber, resin rubber, polyvinyl chloride, ethyl vinylacetate, polyethylene or combinations thereof.  
     
     
         12 . The method as claimed in    claim 7    wherein the insole is made from polyurethane, polyurea, solid rubber, microcellular rubber, resin rubber, polyvinyl chloride, ethyl vinylacetate, polyethylene or combinations thereof.
