ThermaCELL Heated Insoles ProFLEX Heavy Duty Insoles now feature Bluetooth Technology so users can control the temperature of insoles via a smartphone. Users can set the temperature for individual insoles, view battery life and pair as many insoles as they’d like to their device.
The insoles also feature a higher capacity battery that is 30 percent more powerful than those in the standard ProFLEX Insoles, providing up to 8.5 hours of continuous warmth per charge. The batteries charge in less than two hours. Like their predecessors, the ProFLEX Heavy Duty Insoles utilize removable battery packs that can be quickly and easily interchanged for all-day warmth and comfort.
