Insole for Shoe

Abstract

An insole is configured to underlie the rear portion (i.e. the area behind the toes) of the foot of a wearer and includes a para-aramid insert in the arch. The insole improves cushioning and support. The insole includes a shock absorber layer, a heel insert, a woven para-aramid polymer fiber insert, and a fabric cover. The shock absorber layer has a cutout formed in a section configured to underlie an arch of a foot of a wearer. The heel insert is disposed beneath the shock absorber layer. The woven para-aramid polymer fiber insert is inserted in the cutout. The fabric cover overlies the airfoam layer.

1 . An insole for a shoe, comprising:
 a shock absorber layer configured to fit within the shoe, said shock absorber layer being configured not to underlie a toe of the wearer, said shock absorber layer including a medial section configured to underlie an arch of a foot of a wearer, said medial section having a cutout formed therein; and   a para-aramid polymer insert being inserted in said cutout.   
     
     
         2 . The insole according to  claim 1 , wherein said shock absorber layer is configured to underlie a heel of the wearer. 
     
     
         3 . The insole according to  claim 1 , wherein said medial section is arcuate. 
     
     
         4 . The insole according to  claim 1 , wherein said para-aramid polymer insert is a woven insert. 
     
     
         5 . The insole according to  claim 2 , further comprising an elastomeric heel insert disposed on said shock absorber layer and configured to underlie the heel of the wearer, said elastomeric heel insert having a different elastic modulus than said shock absorber layer. 
     
     
         6 . The insole according to  claim 5 , wherein said elastomeric heel insert is circular. 
     
     
         7 . The insole according to  claim 1 , wherein said shock absorber layer has a medial to lateral aligned groove formed therein. 
     
     
         8 . The insole according to  claim 1 , wherein said shock absorber layer has a front edge, said front edge including a lateral notch. 
     
     
         9 . The insole according to  claim 8 , wherein said front edge includes an arcuate projection disposed between said lateral notch and said medial section. 
     
     
         10 . The insole according to  claim 1 , further comprising a fabric cover layer overlying said shock absorber layer. 
     
     
         11 . The insole according to  claim 1 , wherein said shock absorber layer includes polyurethane. 
     
     
         12 . The insole according to  claim 1 , wherein said shock absorber layer is microcellular low density polyurethane foam. 
     
     
         13 . An insole for a shoe, comprising:
 a shock absorber layer being configured to fit within the shoe, said shock absorber layer being configured not to underlie a toe of the wearer, said shock absorber layer including an arcuate medial section configured to underlie an arch of a foot of a wearer, said medial section having a cutout formed therein, said shock absorber layer further being configured to underlie a heel of the wearer, said shock absorber layer having a plurality of medial to lateral grooves formed therein, said shock absorber layer having a front edge, said front edge including a lateral notch, said front edge further including an arcuate projection disposed between said lateral notch and said medial section;   a woven para-aramid polymer insert being inserted in said cutout;   a circular elastomeric heel insert disposed on said shock absorber layer and configured to underlie the heel of the wearer, said elastomeric heel insert having a different elastic modulus than said shock absorber layer; and   a fabric cover layer overlying said shock absorber layer.   
     
     
         14 . A system of gender specific insoles, comprising:
 a male-specific insole including a shock absorber layer being configured to fit within a man's shoe, said shock absorber layer being configured not to underlie a toe of the wearer, said shock absorber layer including a medial section configured to underlie an arch of a foot of a wearer, said medial section having a cutout formed therein, and a para-aramid polymer insert being inserted in said cutout, said male-specific insole having a given length and a given width; and   a female-specific insole including a shock absorber layer being configured to fit within a man's shoe, said shock absorber layer being configured not to underlie a toe of the wearer, said shock absorber layer including a medial section configured to underlie an arch of a foot of a wearer, said medial section having a cutout formed therein, and a para-aramid polymer insert being inserted in said cutout, said female-specific insole having a narrower width than said female-specific insole at said given length.
