Insole Foot Warmers - Up to 10 Hours of Heat, Easily Apply with Adhesive - Ultra Thin, Easy, All Natural - Air Activated, Odorless Hot Insole Warmers - Sport Temp

I bought these to wear with boots in snow in Alaska. I was worried they’d be too hot but they were perfect. They stick to your socks so I placed them closer to my toes as they tend to get cold first, and I was comfortable the whole day

The Insole Foot Warmers work great. I work for KC Chiefs and wore them for the AFC championship game. My feet stayed warm and toasty! Of course, I had on thick thermal socks too. Definitely recommend these, especially if you’re going to be outdoors for prolonged periods of time.

Great experience and product

I ride horses and this product really helps. However they have never lasted for close to 10 hours, more like effective for 5-6 hours max.

My granddaughter works at a ski resort as a lift operator so she’s outside for many hours in 0° weather. These keep her feet toasty warm. She loves the ease of these. Comfortable!!

I have been a lifelong user of the brand name. I was happy to see these available for about 1/2 the price. I bought the 20 pair box. To say that I have been disappointed is an understatement. 1st issue is they are about 2x as thick as the brand name. Secondly if you rip them too fast off of the sock they tear in half and activated charcoal goes all over the place. 3rd- they don't produce a lot of warmth. 4th-The edge is so thick that it is cutting my toes in my boots. These are not great. I have used about 10 of them. Just going to throw the rest in the trash and go back to the brand name. Save your money and get the brand name.

Used in Banff , temperature was -18 c , worked so wellHighly recommend, would buy againThey don’t stick to sox

The warmers keep my feet warm, but I had a problem when I got them out of my shoes. The adhesive stuck and didn't want to come out. One warmer ripped and I had to clean up the contents.
