Abstract
Abstract A thin, oversized, waterproof and water vapor permeable oversock which is adapted to be obtrusively worn over a wearer's foot and/or sock within a shoe, sneaker, boot or other type of footwear. The oversock includes a heat sealable, waterproof and water vapor permeable inner liner which is fully enclosed and freely movable within an outer protective shell. A stretchable knit cuff is affixed to an upper end of both the inner liner and the outer shell to prevent the oversock from sliding down a wearer's leg.
