ThermaCELL products and accessories are guaranteed against defects under normal use for one year from the date of purchase. If your product fails to perform satisfactorily because of defects in materials or workmanship, it will be repaired or replaced free of charge.

ThermaCELL\xAC ProFLEX Heavy Duty Heated Insoles utilize similar high-tech wireless thermal technology as other ThermaCELL Heated Insoles, but they feature easy operation from your Apple or Android smart device*, rather than a small remote control. Benefits of operating your insoles with a Bluetooth-enabled application include:
  • There is no need for an extra device (remote control)
  • Know when to recharge or swap batteries with the battery indicator
  • Operate insoles together or independently
Based on the heat setting chosen on your ThermaCELL Heated Products App, ProFLEX Heavy Duty insoles heat to a specific temperature, providing you with just the right amount of warmth so your feet don't overheat then sweat and freeze. Like the thermostat in your home, Heated Insoles reach the temperature of your choice\x84then temporarily turn off\x84coming 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 4,250 hours of warmth.

Designed with comfortable and durable materials for optimized cushioning and stability, the insoles will endure all-day pounding to help you stay on your feet all day long. They are so durable that they tested successfully to over 1 million footsteps! Additionally, ProFLEX Heavy Duty feature removable, replaceable extended life batteries so you can swap them out without having to take the insole out of your shoes or boots. And these batteries feature a resilient, shock-absorbing Poron battery cover for added cushion and protection.

Keeps your feet warm
February 7, 2021
They work great, battery life is very good, and the APP makes it easy.

Absolute Garbage
December 14, 2020
After trying 3 different pair I have come to the conclusion that these are the worst product ever created. The bluetooth will not stay paired rendering the insoles useless. you have to remove your boots, remove the battery, and repair. over and over. This coupled with the fact that the warming store acquired this product from Schawbell (thermacell), and no longer supports the app - makes them an obsolete, worthless, expensive product.
  • None
  • Useless product that's expensive

Exactly what I needed
November 6, 2020
These insoles fit perfectly in my boots without any cutting. The sizing chart was a big help.
I have used my insoles twice so far and they do what I need them to do. It is nice that they are wireless and I don't have a remote that I will eventually lose. Pairing with my phone was really easy with the instructions that came in the package. Can't wait to see how everything goes when the temps get colder. I am predicting I will no longer have to suffer with cold feet.
Thank you ThermaCELL

Have only used a few times so far, but what I have experienced they work great, they keep my toes warm, easy to use. I had bought battery operated socks from local outdoor store these insoles way better in my opinion
  • 1 Work well 2 can use in any shoe or boot 3 don't feel battery at all 4 works blue tooth from my phone so Im not carrying another device in my pocket
  • none so far

After the 3rd time using these. The left foot quit working. Very unhappy with them. And paid $200 for these also. Would not recommend these
