ABSTRACT:
Antistatic footwear uses a conductive layer above a bottom dielectric layer and extending to the peripheral edge of of the bottom layer to form a discharge edge emitting at least a portion of the static electricity built up with movement of the wearer. The discharge automatically keeps the electrostatic charge to a relatively low level, either eliminating or reducing the intensity of any spark occurring when the wearer touches a grounded object, and yet the wearer is preferably insulated from ground to prevent hazardous electrical grounding of the wearer. The static electric potential on the wearer can be lowered further by forming a conductive path from the conductive layer to the underside of the bottom layer.
