Technology
EliteFit Sport Liner:
This liner blends comfort and performance with a medium-volume fit and supportive ankle pockets. It’s great for intermediate to advanced skiers looking for all-day skiability without sacrificing 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:
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
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
Dual Cuff Alignment:
Dual sided cuff alignment for +/-2 degrees of cuff adjustment.
