Technology

• EliteFit Plus Liner: EliteFit Plus provides a comfort-first fit with plush foam and a more relaxed shape. Perfect for recreational skiers or those with wider feet who prioritize warmth and cushion.
• 40MM Velcro Strap: A versatile mid-width VELCRO® power strap that balances ease of adjustment with solid cuff closure. It adds extra responsiveness to boots without added bulk.
• 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. Mindbender, Anthem, & Recon BOA® models range 97mm - 100mm Cortex BOA® models range 96-98mm. BFC BOA® models range 100mm - 103mm (104mm with heat molding)
• 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.

• Liner featuring Ski Edge Sensitivity Shims: Ski Edge Sensitivity allow the skier to tune edge initiation of the ski. SES Shims on Medial side of liner Cuff produce more inside edge angle. Skis feel more reactive and quicker to edge, excellent for slower more precise skiing. SES Shims on the Lateral side of liner Cuff produce less inside edge angle. Skis feel more controlled and more stable, excellent for higher speeds.

• Full Lace Up Liner: Lace up liner for the optimal liner fit
• Adjustable Liner Tongue: Tongue is attached with velcro in the tow box and can be adjusted to help provide the optimum fit across the top of the foot
