Warm feet at last. The integrated heating element in these socks wraps your feet and toes with electric warmth and are great for super-cold conditions when you're sitting still or for crawling into a cold sleeping bag at night. The 2 battery packs (one for each foot) are rechargeable. The temperature settings can also be controlled from the battery or via your Bluetooth-equipped smart phone. This slim fit version is ideal for narrower feet.
- Socks are made of thick blend of synthetics and merino wool that provides good moisture wicking
- Ergonomic knitting for a soft toe seam, strategic padding on the shins and a great fit
- Integrated heating element completely wraps around both the top and bottom of the toes as well as the forefoot for the ultimate in cozy warmth
