## Description

Thermal Insole, 13 in. L x 4-1/4 in. W, PR : desertcart.in: Shoes & Handbags

Review: Didn’t make a difference for warmth.
Review: 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!
