ABSTRACT:
Electrostatic footwear in the form of a cover with a sole and an upper having an opening to receive the foot or shoe of a user. The opening may be provided with elastic or an elastic cuff for retention about the user. The cover may be worn over the foot or the shoe of a user. The cover has an excess electrical charge to attract particulate matter including but not limited to dust, dirt, pollen, and dander. The electrostatic charge causes the particulate matter to be drawn and held thereon as the user moves about. The sole may include anti-skid material over a limited portion thereof to prevent the user from sliding or slipping.
