Abstract

A footwear insole includes a base layer configured to overlie a sole of an article of footwear, a moisture permeable layer overlying the base layer, and an airgap structure captured between the base layer and the moisture permeable layer. Perimetric edges of the base layer, the airgap structure and the moisture permeable layer are aligned to form an insole perimetric edge.

Claims

exact text as granted — not AI-modified
1 . A footwear insole, comprising:
 a base layer having a top surface, a bottom surface and a perimetric edge, the base layer configured to overlie a sole of an article of footwear;   a moisture permeable layer having a top surface, a bottom surface and a perimetric edge, the moisture permeable layer overlying the base layer;   an airgap structure having a top surface, a bottom surface and a perimetric edge, the airgap structure captured between the base layer and the moisture permeable layer with the top surface of the airgap structure adjacent to the bottom surface of the moisture permeable layer and the bottom surface of the airgap structure adjacent to the top surface of the base layer, and   the perimetric edges of the base layer, the airgap structure and the moisture permeable layer aligned to form an insole perimetric edge.   
     
     
         2 . The footwear insole according to  claim 1 , further including stitching spaced from and parallel to the insole perimetric edge, fastening together the base layer, the airgap layer and the moisture permeable layer. 
     
     
         3 . The footwear insole according to  claim 1 , wherein the airgap structure further includes multiple layers of a mesh material, each layer having crossing strands defining apertures therethrough. 
     
     
         4 . The footwear insole according to  claim 3  wherein each of the multiple layers of a mesh material is a polypropylene mesh having a thickness of 0.012“ and having apertures with a size of 0.014”. 
     
     
         5 . The footwear insole according to  claim 4  wherein the multiple layers of a mesh material include at least three layers. 
     
     
         6 . An article of footwear comprising:
 a sole having a top surface; and   an insole comprising:
 a base layer having a top surface, a bottom surface and a perimetric edge, the base layer overlying the sole with the bottom surface of the base layer adjacent to the top surface of the sole; 
 a moisture permeable layer having a top surface, a bottom surface and a perimetric edge, the moisture permeable layer overlying the base layer; 
 an airgap structure having a top surface, a bottom surface and a perimetric edge, the airgap structure captured between the base layer and the moisture permeable layer with the top surface of the airgap structure adjacent to the bottom surface of the moisture permeable layer and the bottom surface of the airgap structure adjacent to the top surface of the base layer, and 
 the perimetric edges of the base layer, the airgap structure and the moisture permeable layer aligned to form an insole perimetric edge. 
   
     
     
         7 . The article of footwear according to  claim 6 , further including stitching spaced from and parallel to the insole perimetric edge, fastening together the base layer, the airgap layer and the moisture permeable layer. 
     
     
         8 . The article of footwear according to  claim 6 , wherein the airgap structure further includes multiple layers of a mesh material, each layer having crossing strands defining apertures therethrough. 
     
     
         9 . The article of footwear according to  claim 8  wherein each of the multiple layers of a mesh material is a polypropylene mesh having a thickness of 0.012“ and having apertures with a size of 0.014”. 
     
     
         10 . The article of footwear according to  claim 9  wherein the multiple layers of a mesh material include at least three layers.
