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

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).

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

Dual Cuff Alignment

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

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.
