My husband works outside all winter and his feet get very cold. I was so excited when I was asked to review ThermaCELL's Heated ProFlex Heavy Duty Bluetooth Operated Insole. There are no wires hanging down to tangle in. You operate the amount of heat you want sent to your insole through the hand controlled app on your phone. Just simply download this app on any iPhone or Android phone. Carry the phone and if you need to turn up the heat, or turn it down, just use the installed app. to do whatever you need.
