ThermaCELL Heated Insoles will transform how you spend time outdoors waiting for that trophy buck to appear. When faced with bitter cold conditions, they can provide your feet with continuous warmth for up to five hours. A high-tech wireless remote control gives you the power to adjust the temperature between medium heat (100°F), high heat (111°F) and no heat, all while your feet remain comfortably inside your shoes or boots.
