These liners were bought to replace the worn-out ones from a pair of Sorel's acquired at a  local Goodwill. Anyway, they are pretty nice, but a bit of a weird fit in the boot. Really though, they are much better than the other ones, and I was still satisfied with the purchase. It was funny that the boots were only about 16 bucks compared to the cost of these (near 30 when I purchased) On a side note, I have another pair without the sealed up front part of the sock-liner thing,and I feel that the seamed up one such as this model is a bit warmer and comfortable.
