How ProFLEX Rechargeable Heated Insoles Work

How It Works

Based on your remote setting, ThermaCELL ProFLEX Heated Insoles heat to a specific temperature, providing you with just the right amount of warmth. Like the thermostat in your home, Heated Insoles reach the temperature of your choice—then temporarily turn off—coming back on when more heat is needed. Smart-charging technology ensures the battery is fully charged in each Heated Insole, turning your regular cold-weather shoes into 2,500 hours of warmth. These insoles are designed to warm up to specific temperatures where you will remain warm and comfortable, but don’t overheat and sweat. 

ProFLEX Heated Insoles utilize an insulated layer between your feet and the bottom of your shoes or boots to stop heat from escaping. These insoles offer even more comfort and ease-of-use than Original Heated insoles. The water-resistant fabric liner absorbs any moisture, and the molded, flexible polyurethane material provides the dry comfort you’ll need to keep the cold from bringing you inside. Additionally, ProFLEX Heated Insoles feature removable, replaceable batteries so you can swap them out without having to take the insole out of your shoes or boots.  And these ProFLEX batteries feature a resilient, shock-absorbing Poron battery cover for added cushion and protection.

What Makes ThermaCELL Heated Insoles Stay Warm?

The antenna receives the signal from your wireless remote control, passing those to the control board. This cutting-edge control board is the “brain” of ThermaCELL Heated Insoles. It interprets the signals from the antenna, and controls the heater based on that information. Paired with the same type of battery used in mobile phones and laptop computers, the rechargeable lithium-ion polymer batteries are thin, lightweight and tough enough to take a beating. Unlike the Original Heated Insoles, ProFLEX Insoles have a removable, rechargeable battery that is easily removed. Simply replace the dead batteries with a second, charged battery pack set and enjoy your favorite cold-weather activity even longer!
