Abstract
The present disclosures concerns embodiments of a footwear insole that can be used with various types of footwear, including, without limitation, shoes (including open and closed toe shoes), boots, sandals, etc. The insole includes an upper fabric layer that comes in contact with the foot and a cushioning base layer that contacts the footbed of the footwear. The base layer desirably is formed from a self-adhering material that can be applied to in liquid form to the fabric and bonds directly to the fibers of the fabric when cured, so as to eliminate the need for a separate intermediate adhesive layer for securing the fabric to the base layer. The base layer is also configured to substantially prevent shrinkage of the insole when subjected to multiple wash and dry cycles.
