Heat Factory's adhesive Foot Warmer Insoles are designed to be worn with socks inside of shoes, boots, and other air-restricting footwear. These insoles provide up to 6 hours of reliable, even heat. The Foot Warmer features an adhesive backing that adheres to the bottom of your sock, allowing it to stay in place when walking, biking, hiking, skiing and other activities. The insole foot warmer has an ultra-thin design for comfort and measures the full length of an average insole to ensure your entire foot stays warm. These are soft, lightweight pouches containing a biodegradable mixture of iron powder, charcoal, salt and vermiculite.
