My daughter, who suffers from Raynauds Syndrome, would be unable to function normally without these foot warmers. Not only have they enabled her to continue to compete on the track team, but she is now able to comfortably endure outside winter temperatures while waiting for the bus. Without these foot warmers, she certainly would not have been able to enjoy a winter trip to Europe, where her sightseeing group walked several miles a day in cold temperatures. These foot warmers have been such a lifesaver for her!

As it turns out, these foot warmers have also been a godsend for my daughter's grandmother, who has poor circulation and chronically cold feet. During a recent visit, we let her use one of my daughter's foot warmers so that she could accompany us on a walk in 30-degree temperatures. She was so thrilled with their effectiveness that before the day was out, she was on the computer ordering TWO full boxes of them! We can't say enough for this product.

These really help to keep feet warm in snow and frigid temps. Highly recommend them for people who's feet are always cold outside.

I used these for the first time this year during my elk hunt in Colorado. I've used "toe" warmers in the past from another company and was not impressed. These have more coverage under the foot and worked much better. I used these inside Muck Arctic Sports with a wool insole. I covered approximately 2 miles of hiking in deep snow in the morning and evening (4 total per day) getting to and from my blind. They stayed where I put them and never bunched up in my boots. I wore them for about five hours at a time and they worked for that long. Don't know about the seven hour claim. I even tried a pair in each boot top and bottom of my foot on a day when I was using a different blind and knew I would be standing for about four hours. Kept my feet nice and toasty. I had purchased the 30 pack and loaned a few pairs to other hunters in camp that had trouble with cold feet. I had to keep an eye on my warmers after that because they wanted to try more of them. The ranch owner even grabbed a pair now and then to wear inside his cabin slippers to warm his feet at the end of the day. I recommend these because they worked for me.

I use these at work year around cause I work in a 32 degree cooler. It helps me from not getting cold.

I am a deer hunter and spend many hours in a tree stand. These insoles work great to keep my feet warm! They will not replace high quality wool socks, but they are a great addition to your cold weather gear. When it's cold outside, I will always use these!
