K2 Ski Boots

Our focus and commitment for the past 50+ years is to skiers who ski the entire mountain, in all conditions. This same philosophy holds true in ski boots. We did not start with a rigid, intimidating race boot. We wiped the slate clean and built our boots from the ground up to maximize efficiency, optimize power transfer, and deliver performance over a wide range of terrain and snow conditions. The result is a complete line of ski boots that fit and function unlike any other boot, with a style that is uniquely K2.
