ThermaCell Rechargeable Heated Insole & Remote Control

I was a bit worried about this purchase due to so many negative reviews. But these insoles have exceeded my expectations. Even just having the insoles in keeps my feet warmer than normal, due, I guess, to the added insulation. Turn them on, and…ahhh…nice and toasty, even in 15 degree weather. The insoles are a bit hard compared to what I’m used to and have less arch support, but they are not uncomfortable and the heat is worth it. My only suggestion is that you wear them in work boots with the original insole removed; or, if you plan on using any other type of shoe, go up half a shoe size. These are thicker than normal insoles and can feel a little tight. I also wanted to adress the frequent complaint that the insoles dont heat at all. I think the problem might be the tiny on/off switch located near the charging plug. It’s small and easy to miss, especially if you’re a guy who doesn’t read the directions. If the switch isn’t on, of course they won’t heat. And if the switch is left on, even on the no heat setting, the battery will go dead within a day. So mind that switch! All in all I really enjoy this product so far and mine stay heated for about 4 hours on high.
