ABSTRACT:
A foot covering article adapted to be worn over the bare foot and directly underneath a sock for the purpose of preventing the formation of blisters when engaging in athletic activities and the like. The article is made of a single, porous, non-woven film-fibril sheet of plexifilamentary strands, wherein the sheet is consolidated by a large number of very small point bonds, and includes a plurality of minute perforations extending through the thickness of the sheet. The sheet is formed into a foot enveloping shape comprising a bottom portion which covers the sole of the wearer's foot, side portions extending upwardly from the bottom portion, a heel portion which covers the heel of the wearer's foot, and a front portion which covers at least the forward portion of the top of the wearer's foot. The article has a smooth inner surface so that there is minimal friction between the wearer's foot and the article, and an outer surface which is rough, relative to the character of the inner surface, so that stability between the article and either the sock or shoe which is adjacent thereto is enhanced. An important property of the sheet material is that the degree of friction which is present between it's inner surface and the wearer's foot decreases as the material is repeatedly crumpled. Thus, the blister preventative character of the article increases with use.
