Our insoles provide continuous heating as long as the attached battery pack has charge, so you can keep warm for as long as you'd like. The warming time is varies from a few seconds to a few minutes depends on different environmental conditions. The insoles can heat up to a temperature of 50°C/120°F to warm cold feet in winter without causing sweating.

The Ergonomic Concavo-convex surface of ThermaSoles is designed to tailor to different foot sizes. ThermaSoles come with multiple clipping areas to cut out to your foot size without unraveling or fraying. The multiple cutout areas make sure ThermaSoles are always soft and comfortable with no loose threads and pilling during use.


The battery heated insoles operate on 7.4V, which is rated a low and safe voltage for humans. Our insoles also feature a flexible, PVC fire protection casing to make sure the insoles are flexible, while also keeping you safe at all time and in all conditions.

ThermaSoles are also waterproof, which means they can be easily washed and are suitable to use during heavy snow.

"I put these in my ski boots on a single digit day in Colorado. I love these. They kept me warm all day. They don't get burn-your-toes-up hot, but stayed comfortable for me. I imagine on a warmer day I might unplug them if I get too warm.  With these, I don't have to replace an expensive battery and worry about charging"

Ross H.

"When winter hits and I have outdoor events or chores to do I have a very hard time staying warm long enough to enjoy what I am doing. I got these to try and help me tolerate sledding, and snowball fights, etc with my kiddos. They fit in my boots easily and are comfortable. The actual sole is not noticeable and the wire running to the battery pack is small and stays out of the way. They heat up the whole foot area pretty well, could be better at the toes, but that is the coldest part of my foot normally. The longest I have used them was 3 hours and they lasted the entire time. I didn't pay close attention to how long the battery took to charge. Great insole, wish I had them much earlier in my life."

Jessica A.

"I ALWAYS have cold hands and feet, always have since I was young. My husband and kids got me these insoles for my birthday (kind of as a gag gift) and they are one of my favorite gifts ever! When I know we will be outdoors for a period of time, I charge them overnight. I wore them taking the kids trick or treating, through Hershey park for Halloween and Christmas and while outside on New Years Eve. The rest of my body was freezing, but my feet were nice and warm"
