Thermal electric socks are socks designed to produce heat using electricity from a power source such as a battery pack or outlet. Thermal electric socks are used by those with chronically cold feet, poor circulation, outdoorsmen, athletes and everyday people who wish to stay warm in cold climates.
Battery-powered thermal electric socks are designed to withstand moisture and the cold, making them ideal for outdoor activities such as snow sports and hunting. Some models of thermal electric socks run on standard batteries ranging from AAA to D cell, while others operate on rechargeable lithium ion batteries. Wires from the battery pack run to the heating element found at the toe of the sock, which is responsible for producing the heat until the power source is depleted. Thermal electric socks powered by an outlet continue to produce heat until detached or turned off.
