Abstract
An electrically conductive shoe insole is disclosed for cushioning a user's foot and for transferring electrical charges from the wearer's foot to a conductive shoe. The shoe insole includes a cushioned layer, which contains an electrically conductive material, and a fabric, which is bonded to the top surface of the cushioned layer by a nonconductive adhesive. The fabric contains a noncorrosive electrically conductive fiber interwoven therein. The adhesive is applied such that the electrically conductive fibers in the fabric contact the cushioned layer. This allows transfer of electrical charges from the fabric to the cushioned layer.
