Features

• 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.
• EliteFit Pro Liner - The EliteFit Pro liner delivers a performance-driven fit with precision-mapped support zones and thermoformable foam for custom comfort. Designed for expert skiers who demand responsiveness and foot retention.
• 5355 Alpine Outsole - These outsoles have been tested with bindings representing the full range of release kinematics on currently available alpine bindings and provide release values consistent with ISO 5355-certified boots.
• PP Cuff - Lightweight and durable, our polypropylene cuff delivers consistent flex and reliable support in all conditions. Engineered for comfort and performance, it’s an ideal choice for skiers seeking value without compromising on control.
• 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 Supplied In-Box - 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. Not preinstalled.
• Fastfit Instep - Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
• 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.
• Lace Up Liner - Lace up liner for the optimal liner fit.
• Dual Cuff Alignment - Dual sided cuff alignment for +/-2 degrees of cuff adjustment.
• MultiFit Last - BOA® boots with multi-fit last allow for a greater range of foot shapes to fit within the same shell family. Multi last boots are offered in three different volumes, low volume (Cortex) medium (Recon, Anthem and Mindbender) and high (BFC).
• Fully Heat-Moldable - Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.
