WARMEE foot warmers are activated by air and are ready to use. Just open it from the wrapper and slip it into your shoes like insoles and feel the warmth for 5+ hours. They are ultra-thin so they keep you very comfortable while walking, running, etc. To get the best out of WARMEE foot warmers do not leave them completely in the open after removing from the wrapper. Warmee foot warmers are made of completely safe and natural ingredients like water, salt, carbon, and vermiculite which we use on a daily basis.
