Got cold feet? Try the Women’s Electric Heated Socks from Thunderbolt. The entire sole of the sock has a heating element, and there’s a cable that stretches from the sock up your leg to the battery pack that attaches to your waistband. Plug the cable in and select low or high power when your feet become cold. Once they are toasty warm, unplug the cable to save the power in your battery pack. You’ll be all set for the cold weather!
