Love these. I walk outside in the winter and these keep my feet warm the entire way.

Best product ever for my use! I have spent so much money of different types of socks thinking they would resolve my feet freezing over while playing soccer in sub zero temperature. These are things did the job. They stayed in place, are thin enough to not cause fitting issue and kept my feet warm thru my activity about 3-4 hours

These kept my feet toasty warm. I was really enjoying the warmth. Then I had to walk about a quarter mile to Highmark Stadium in 28° weather. They got so hot that I had to take off my boots and pull them out to keep them from burning my feet. I recommend you take these with you where you’re going and put them inside your boots, once you’re sitting down to ice fish or watch an outdoor game. After they got so hot and I took them out, they never kept my feet warm again when I put them back inside. These are activated by friction, so keep the friction to a minimum until you’re ready to sit down and enjoy them. I’d give them five stars for being overachievers, but I gave them four because the manufacturer says nothing about walking being a problem

Excellent product if you like a sauna experience in your shoes. I was wearing it for 4 hours and ended up removing the insert. Very hot definitely was made to keep your feet hot…

These foot warmers were perfect for my trip into the Arctic ! They actually last about 6 hours and keep your feet warm … do let them sit after unwrapping for a few minutes to activate … they are light weight and fit easily into the side pocket if a suitcase

I bought these to wear in my boots during a cold football game. However, the warmth did not last as long as package indicated. They were comfortable, but only lasted a couple of hours.

Anyone who suffers from neuropathy in their feet would welcome the help from these insole foot warmers. They help me a great deal. When my feet are cold, there is nothing that warms them better than these foot warmers.

These are amazing! How have I never used them before. Great for long cold tailgates!
