ActiVHeat® Heated Sock Liners

Soft, thin sock liners have built-in heating to give your feet the warmth they need, when they need it most. Up to 6 hours of heat at a time—great for skiing, sledding and more! Light, stretchy sock liners have ultra-thin carbon microfibers built in and powered by a compact battery pack. Turn on the liners for two different levels of gentle heat—turn them off when you're working hard and your feet are warm. The heating system is virtually invisible—no wires or bumps, and no shocks, even when the liners are wet.

Great for stop-and-start winter sports and activities—skiing, sledding and more.
Soft liners are highly breathable and wick moisture away from your feet, helping to keep your feet warm and dry. Can be used without the battery packs as a regular performance base layer for your feet. Uses 3 AA batteries per foot for up to 6 hours of heat (batteries not included). Heating time will vary across battery brands and types. Not suitable for use with NiCd or NiMh rechargeable AA batteries. 60% wool/40% synthetics. Hand-washable (remove battery packs first). Imported.
