TECHNOLOGY
ELITEFIT SPORT:
3D shaped PE 160 ankle and heel foam, adjustable 3d shaped Ultralon tongue, molded high performance collar, full lace up design, new Powerfit Pro insole.
CUFF:
Dual Cuff Alignment Index
Dual-sided alignment system for +/- 2 degrees of lateral cuff adjustment.
Energy Bolts
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.
Ski Edge Sensitivity Shims
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.
OUTSOLE:
Gripwalk Outsoles
Removable and interchangeable rockered soles designed to work with Marker’s GripWalk binding system for better grip and comfort while walking, standing, and hiking.
FIT:
BOA Fit System
The BOA Fit System provides a performance fit engineered to enhance feel and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise microadjustments.
FASTFIT INSTEP:
Softer TPU material is used in the instep area of select models’ shells for quick and easy entry and exit.
