Typically, electric or battery operated socks are made from wool (to wick moisture away) and synthetic fiber blends, including nylon and polyester to provide insulation. With battery powered socks, a small pocket compartment at the top of the sock (at the band) houses the batteries. Some electric socks plug into a wall outlet.
Some electric socks have heating elements within the fibers of the entire sock, thus warming the whole foot. Other electric socks warm only the toes. In order to stop heating the socks, you must remove the batteries, as electric socks do not have an on/off switch.
Battery and electric socks can be uncomfortable. The two D-batteries in a pouch on the top band of the sock may cause the sock to slide down your leg. Bring extra batteries if you intend to be out in the elements for an extended period of time.
People who suffer from diabetes, circulatory problems or with heart pacemakers should consult their physicians before using electric socks. The chance of receiving a shock or being burned from the electric socks is minimal, as the batteries have a low voltage, but should be considered.
