Enjoy some time around the house as the snow falls sporting the ActionHeat Adults' 5 Volt Battery-Heated Cable Knit Slippers. The integrated heating design at the bottom of the slippers is encapsulated by a thermal seal to add durability and moisture protection, and the polyester/wool/nylon uppers feel soft and warm on your feet. The strategically-placed heating elements with ultra-fine fibers help boost the heating panels' power by helping the heat stay trapped inside the slippers, and the polyester fleece linings add softness and additional warmth.
