BOA® Fit System on the Cuff and Shell:

The BOA® Fit System shell 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.

The BOA® cuff single cable design allows the tension to self equalize always giving a consistent pressure to the shin. The improved wrap allows for better power transmission and improved comfort even at high tension

H+i1 DIAL:

Provides micro-adjustable, precision fit and quick release, with quality and durability guaranteed. The BOA dial platform features a breakaway design engineered to eject the dial cartridge upon severe impact without damaging the system, allowing skiers to pop the dial back into the bayonet midmountain. In the unlikely event that the system is broken, it can be easily repaired and replaced.

BOA® FIT SYSTEM: DIALED IN:

Precision fit with on-the-fly tightening and loosening for enhanced responsiveness, optimized pressure distribution, and reduced pressure points.

BOA® FIT SYSTEM: LOCKED IN:

Connected fit designed to uniformly wrap the foot and minimize downward pressure, increasing heel lock-down for improved power and edge-to-edge control.

BOA® FIT SYSTEM: CONFIDENT:

Engineered for confidence and built to withstand rugged terrain and inclement weather, BOA® dials and laces deliver extreme durability. Bayonet and cartridge system ensures continued operation, even after heavy impacts.

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.

Fastfit Instep:

Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.

Dual Cuff Alignment:

Dual sided cuff alignment for +/-2 degrees of cuff adjustment.

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.

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.

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
