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.

A waterproof oversock comprising:
- an inner liner composed of a waterproof, water vapor permeable, substantially nonstretchable composite fabric, said composite fabric including a substrate fabric having a layer of a heat sealable, waterproof and water vapor permeable material laminated thereon, said inner liner having an oversized, foot shaped body for enclosing a wearer's foot, said foot shaped body including an aperture at an upper end for receiving a wearer's foot therein;
- a substantially nonstretchable, protective outer fabric shell for enclosing said inner liner, said outer shell including an oversized, foot shaped body;
- and
- means for securing the foot shaped body of said outer shell about the foot shaped body of said inner liner, wherein the foot shaped body of said inner liner is freely movable within the foot shaped body of said protective outer fabric shell.
