Abstract
A shoe cover is described for use in dust-free and decontamination rooms, as protective rainwear, or the like, characterized in that it is made as a one-piece unit of thin, pliable, elastic material including a sole portion and a top portion formed in the shape of a foot to tightly enclose the complete wearer's shoe and to extend slightly above and to grip its upper edge, the outer face of the shoe cover being formed with a network of ribs which increase its tensile and shear strength, isolate tears, and reduce slip. Also described is a method of making the shoe cover wherein a form is dipped obliquely into a latex bath after having been coated with a coagulant, is dried, and is then stripped of the produced shoe cover.
