The FNDN rechargeable heated liner socks with long working hours and cozy temperature will keep your feet warm and comfortable all day long. The material is a moisture-wicking, breathable stretch fabric that's thin enough to be worn under other socks or by themselves in tight form fitting situations. Powered by Radiant Core Heat™ technology and USB rechargeable BEGO battery system, these socks offer enough warmth to provide great relief from poor circulation, arthritis, Raynaud’s Syndrome and any kind of winter cold issues. Forget about frozen toes or discomforting pain in the winter mornings or evenings with FNDN
