Why We Like The Lenz 4.1 Heat Sock

The Lenz 4.1 Heat Sock provides warmth to the foot during outdoor winter activities with a sewn-in Toe Cap heating element above and below the toes. A mixture of Merino wool and technical fibers adds warmth to the rest of the foot and calf while absorbing moisture, as a ring bandage and left/right knitting ensures a perfect fit.
