HotHandsToe Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 8 Hours of Heat - 72 Pair

I’ve bought cheaper brands before but always go back to hot hands. They seem to heat the longest. They could be a little larger, I have smaller/average feet and would love for them to be bigger. They stick to your socks just fine. They last me all day outside. They are comfortable to wear, I hardly notice them on. I think the work really well

Used these for a big sled dog trip in the Boundary waters and they kept my feet warm. Opened the package to get oxygen to it about 30 minutes before putting them in my boots. They stayed super hot for a full 9 hours before starting to cool down. It was a high of 15 degrees with 20mph winds. I was outdoors for over 12hrs and even though they stayed toasty hot for 9 of those hours, my feet never got cold as they slowly cooled down. Great product.

Definitely made a difference and saved me from chillblanes this winter.

They are comfortable and effective.

I've purchased these a few times now, so far without complaints. They keep changing the packaging and the formula I don't particularly care for but the product hasn't seemed to suffer none from it. Now last year some time I did purchase a box that only about half the packs worked, I think I got a bad batch or maybe old stock. That only happened that one time and I've had a pretty good experience with the product.

These are always steady with the heating power and duration. I've tried other brands that fail to do so and worse, they have broken open and spilled out the black and messy charcoal all over. Not these, these are great.

My dad has had issues with cold feet his entire life, and it has only gotten worse with age. He has literally worn boots to bed. At the moment, we're managing with layers of socks...and these foot warmers. He usually uses 2-3 per foot when he goes to bed. They definitely provide warmth and help him sleep. That said, they don't last 8 hours. Yes, they say "up to", but I've never seen them get close and it's not as if we're using these in extreme conditions.So 4 stars instead of 5 for not lasting that long, but they are still a lifesaver. Definitely recommend.

I use these every time I spend much time outside in the cold.
