When you're sailing through alfredo rich couloirs or flying faster than the speed of light down your dream line of choice, you can count on the Dalbello Men's Krypton Pro I. D. Ski Boot to take you the distance. Designed with a center balanced Rocker stance, the Krypton utilizes a low footboard ramp and upright cuff to provide optimal performance on rockered skis and efficient power transfer with the least amount of quad fatigue. The boot features a stiff 130 flex and narrow 98mm last, enabling expert level performance, power, and sensitivity required for exploding through technical ravines, launching cliffs, and leaning clean into the mountainside. Built for enduring a bar fight with a yeti, the shell and cuff are crafted with rigid polyurethane for stone solid lateral stability and power transmission at max speeds, while the Kinetic Response tongue available with interchangeable stiff and medium offerings is made with a flex ribbed, polyamide design, that sits flush with the leg, perfect for sending on steep faces or traversing through tricky terrain. The three piece design Cabrio architecture is specific to Dalbello and combines the geometrical anatomy of the boot, shell, and cuff technologies for a dynamic, progressive flex and and lateral support on irregular terrain. Designed to fit like a glove, this boot is equipped with heat moldable I. D. Thermo Pro liner, ergonomically designed Contour 4 Shell fit, as well as multiple canting, flex and lean adjustment options. The midfoot Dynalink retention system attaches to the shell and hugs your heel securely within the heel pocket without interfering with the boot's flex, while the F16 aluminum buckles are easily adjustable for a fine tuned fit. The bootboard comes with two options: shock absorbing or firm, so you can break free from sloppy seconds.
