These rechargeable heated insoles are comfortable, versatile, and easy to use. They come in four sizes, and can be easily cut to size if they are too big - just make sure you cut around the sizing markings on the toe and don't cut the heel, where the battery is located!

"They don't heat up very warm at all, very disappointed especially for the price. Would not recommend this product."
