Insole Foot Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 9 Hours of Heat - 16 Pair, Black

I work on an outside dock year round, and i hunt. I live in Western New York, and as any resident of the great lakes will tell you, its not the cold that gets you as much as the dampness dose. The insoles are advertised as "size 9 - 11" keep in mind they will be smaller than the actual size indicated, otherwise they would not fit in your boots. This leads me to my next point. You will need to wear a good pair of boots with these warmers to realize the full potential of them. Wear at least an 800 milligram thinsulate boot. Old style foam insulated boots, fashionable dress boots, uninsulated leather boots or work shoes and sneakers will not hold the heat, this is not the insoles fault, its the footwear's. Heat loss and thus the numbing cold you experience is the result of heat transfer from your sole to what ever surface your walking on. If you want an added measure of insulation use Dr. Scholl's insoles under these to help keep the heat in your boots. The insoles do last up to 8 hours, however these have a shelf life and if you have older ones in your inventory they will not last as long. But fortunately the self life is long, i have used insoles that were 4 years old and still realized about 4 to 5 hours of heat. Walking around dose keep your feet warm, and distributes the heat generated by the insoles, but to much walking will make your foot uncomfortable hot. If your foot is to big to be totally covered by the insole get the toe warmers to place in the front of your boot, and keep the insoles on your instep and heel. If used properly and with the right foot wear these insoles will give you hours of comfort in cold conditions as low as negative four degrees F, yes i said (-4)F! I cannot comment on colder temperatures, as the coldest the dock ever got to was -4, but i can say walking on a concrete platform for hours on end, on a -4 night with these in my boots kept my feet warm to the point where i was comfortable. These insole work very well when used properly, i highly recommend them!

My child works in a barn during the winter, and these HotHands Insole Foot Warmers have been a total game-changer for her! The cold can be brutal when you’re out there mucking stalls or taking care of the animals, but these foot warmers keep her feet warm and comfortable for hours. They provide up to 9 hours of heat, which is exactly what she needs to get through her long shifts.She just slips them into her boots, and they warm up quickly. They don’t make her boots feel heavy or uncomfortable, and the warmth lasts all day. With how cold it can get in the barn, these foot warmers make such a big difference. They’re odorless and natural, so she doesn’t have to worry about any unpleasant smells.If you’re working in a barn or anywhere outside in the cold, these foot warmers are a must. They’re so effective, and she’ll never go without them now

Love these feet warmers. I use them all The time to keep me warm. I am always cold so I wear these daily attaching them to my knee highs.

Works great!!

First and foremost -- they work for me. I have been spending a lot of time this winter standing in a garage with a concrete floor, and although it is a heated space the heat is nominal and the floor is one huge slab of COLD. I tend to be comfortable enough in general but my feet get cold pretty quickly and stay that way. I don't want to wear heavy insulated boots, and insulated socks didn't help. These do. Put simply -- my feet aren't cold anymore. I can't say that they feel extra warm, just normally warm, certainly warm enough to stand on that floor all day long. The inserts do feel lumpy under my foot so I don't know how much fun it would be to go on a hike. And I would like more focus on my toes whereas these favor the arch more. That's why 4 stars instead of 5. All in all I am very satisfied.

I always use these when skiing! My feet usually freeze and these definitely help keep them warm. Much better than the toe warmers. Glad to have found a bulk pkg, they are getting harder to find in stores!One set will last me an entire ski session of 4 hours or so. Once attached to my sock and my foot is in my ski boot, I'm good to go and only know I have them on because my feet are warm! These are definitely a ski day savior for me and my family.

i work outside in a cemetery in the norhteast and its winter now. My feet are always freezing. Thes worked great and kept my feet warm and from getting numb as usual. My only complaint woukld be that thery shold be a little longer and wider to cover the entire bottom of my foot. Except for that they are great and last all day and on the ride home too! If you have cold feet from snow or winteer conditions I highly recommend these!

Ease of use:They’re easy to use.
