The Heat Factory Footwarmer Insole is a soft, light-weight pouch containing an inert mixture of iron powder, charcoal, salt, water and vermiculite. When exposed to air, a natural exothermic reaction generates consistent and prolonged heat. The insole pouch is made of soft cloth lined with a very thin layer of porous plastic for maximum durability. Peel back the adhesive backing and press warmer to outside of sock underneath foot.
