The original, the classic, the tried-and-true cold-weather performer: the Sierra Designs Down Bootie. 650-fill goose down keeps toes warm when all else fails and the feather-proof nylon shell material features a DWR to shed water and a silicone coating for reliability. Plus, should you be overcome with the need to show off your best dance moves, an internal EVA footbed and nylon non-slip sole support the feet.
