If face-melting speeds, sphincter-clenching cliff drops, and massive straightlines are in your future, count on the Dalbello Men's Krypton KR 2 Pro I. D. Ski Boot to join you for the ride. Designed to optimize performance on ultra-wide and rockered skis, the KR 2 Pro feature a 130 flex index and anatomically precise 98mm last that provide expert-level performance and sensitivity.

Thermo Pro liner supplies a 100% custom fit designed to eliminate relative movement between the liner and shell for improved response, accurate and powerfulenergy transfer to the ski, and better control.
