If you're like a lot of us, you've lusted after the Krypton for years but could never tolerate the narrow last for more than a few minutes. Enter the Dalbello Krypton AX 120 ID Ski Boots and get on with it while allowing your feet a little breathing room. An average 100 mm last and full ID heat moldable liner make all the difference, and allow most average width and volume feet a comfortable fit without drama.
