Abstract: A waterproof sock according to the present invention includes a sole portion constructed of a waterproof material and an upper portion constructed of an air-permeable material. The sole portion extends about a toe region for protecting a wearer's toes from wetness or from being inadvertently scraped. The waterproof sock includes a pocket situated atop a front region of the upper portion and is configured to receive and retain heat packs. Alternately, pockets may be situated on opposed sides of the upper portion for warming both sides of a wearer's foot. Accordingly, the waterproof sock enables a wearer to keep his feet warm and dry and in a cold and wet environment such as a ski lodge.
