Thermal Insole, 13 in. L x 4-1/4 in. W, PR

Didn’t make a difference for warmth.

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!

Really helps in cold weather

Seem thick enough. Would be nice if it came with a template to cut out different sizes. The boots I wanted to put them in didn't have insoles so I didn't have a template to cut out these new inserts. They are cushy, but don't hug the feet. They're flat.

These are great! I removed the original Sorel boot insole which was very thin and installed these and what a difference…a lot more cushion and it also helps insulate my feet when standing on snow or frozen surfaces
