Little HottiesThermal Insole, 13 in. L x 4-1/4 in. W, Gray, Unisex, Shoe Insole

I have had size 10 Sorel Winter boots (they run quite large) for about 8 years. The bottoms of my feet would get cold after about 2-3 hours of being on the ice, when Ice fishing. These Thermal Insoles slid right in without any cutting or adjustment of sizing and they perfectly fit my Size 10 Sorel Boots. Then I put my Sorel Liners on top of these insoles and my feet did not get cold at all in over 5 hours of being on the ice in 5-degree temperatures.I'm incredibly impressed and would recommend these to anyone looking for more comfort and warmth in your boots!

How could a little piece of felt keep my feet so warm. Idk, but it's amazing how well they work. My feet are always toasty warm and comfortable

Works well. A little less supportive than the OEM insoles but warmer.

I bought a pair of these at a store in 2023 for a pair of boots. Living in a state with snow #5 or more months a winter & having a health issue with the cold I hoped they worked. And they did much to my surprise. So this year 2024 I bought #2 more pair for #2 more pair of boots. And they worked perfectly :) Thank You for the warm comfortable insoles. They are Great!!!! Angel

These little hotties thermal insoles are the warmest insoles I have ever put in a pair of work boots that didn't use a battery. The were very easy to cut down to size and install and are of very good quality and comfortable. I will purchase again if needed.

Always warm and comfy, work In a 30 degree environment or less and this never fails, only downside is you need Mad thick scissors to cut throw the foam, wish they mad smaller sizes 🤔

To keep my feet warm

The description says "13 in x 4-1/4 in", but that is not correct. The insole is only 11 inches long, about a US men's 11. I had to return them, as I needed a longer length to match the insoles that came with my boots. Otherwise, the insoles look fine as far as the materials and quality. If your shoe size is 11 or less, they will work fine. You will need to trim to size.
