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.
