Cuff Adjustment

45MM Cam Buckle Strap: A wide cam-style power strap that delivers maximum cuff support and precise closure. Ideal for high-performance boots where stiffness and control are key.
GripWalk Outsoles: Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.
Fastfit Instep: Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
BOA® Fit System: The BOA® Fit System delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.
MultiFit™ Last: The MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 96mm to 104mm, eliminating the need for multiple last options.
True LV Fit: All new low volume last featuring our narrowest heel and ankle while maintaining a little room in the forefoot and toe box for an all day performance fit.
Energy Bolt Spine: A bolted rear cuff gives Cortex excellent rearwards support and a precise forward flex. The top bolt can be removed to allow for a more progressive cuff response and slower rebound.
Dual Cuff Alignment: Dual sided cuff alignment for +/-2 degrees of cuff adjustment.

Carve hard, charge harder.
