Abstract
Abstract A sanitary and protective foot and shoe cover is formed of a single sheet of flexible material. A top opening in the cover accommodates the leg of the wearer. The cover includes a continuous seamless bottom sole portion and a top portion having a forward toe and rear heel seam extending upwardly from the sole portion to the leg opening. An elastic band is provided about the opening and through the forward toe seam to provide a covering over the foot which generally conforms to the foot and is resiliently attached thereto. A conductive tape is sewed to the seamless sole portion and is extended upwardly through the protective cover at the non-elasticized heel seam.
