We like it How the Dalbello Krypton AX TI Ski Boot combines our longtime favorite Krypton chassis with a reliable walking mode and lightweight materials that will help us take our bag of tricks into the backcountry. Cuff rotation 33° , controlled by a powerful walking mode lever helps us reach the top of dreamy lines. On the descent, stiff flex and a relatively narrow last lock your feet in place , ensuring confident riding.
