The fit is noticeably more snug than the stock liner, and the extra warmth is a game-changer for cold days on the mountain. A solid upgrade for anyone who wants a better feel inside their boots.

I swapped these into my boots and noticed the difference immediately—the heel hold is much snugger without being tight. They warmed up after just a few runs, which was a welcome surprise for a replacement liner.
