ABSTRACT:
An insole for an article of footwear which includes an apertured top layer formed of a non-absorbent, thermally non-conductive thermoplastic material, a non-woven layer having a first portion formed of a mixture of moisture-wicking and moisture-absorbent fibers affixed to the top layer, and, optionally, a second portion including fibers which are non-adsorbent and non-absorbent, and, in various embodiments, a barrier layer and/or cushioning layer(s) forming a laminate in which the non-woven layer is sandwiched between the top layer and such other layers. The chemical formulation of the top layer of thermoplastic material can be varied to alter its coefficient of friction or degree of slip resistance of the insole depending upon the requirements of a particular application.
