ThermaCELL ProFLEX Heated Insoles use state-of-the-art wireless thermal technology with a built-in thermostat. They will keep your feet warm without getting hot to the touch and making them sweat. It’s the best way to keep your feet warm while hunting, fishing, or working outdoors. The ProFLEX insole offers more comfort than the original heated insoles, utilizing a flexible polyurethane insole material, resilient poron battery cover cushion, and removable, rechargeable battery. These heated insoles offer remote operation with no wires or external batteries. They provide at least 2,500 hours of use or 4 winters of heavy use. The insoles are easy to use, just adjust the temperature using the wireless remote control to the setting of your choice, no heat (stand by), medium (100 degrees Fahrenheit), or high (111 degrees Fahrenheit).
