Alpenheat Heated Fire-Sock Size 36-38

FIRE-SOCKS, the heating socks from ALPENHEAT, keep your feet cozy warm and are extremely comfortable to wear. The heating element is embedded in the sock under the toes and is powered by a small, compact battery that fits into the pocket at the top of the sock. With the 3 heat settings of the socks, you will stay warm for 5–10 hours. Special copper wire has been woven into the socks to prevent the growth of bacteria, eliminate unpleasant odors, and extend the lifespan of the socks. The batteries and heating element have been optimized for use in cold temperatures. The batteries can be charged either with the USB cable or via the charger and household power supply.
