H+i1 DIAL:

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.

These outsoles have been tested with bindings representing the full range of release kinematics on currently available alpine bindings and provide release values consistent with ISO 5355-certified boots.

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.

Adjustable Liner Tongue:

BOA® FIT SYSTEM: LOCKED IN:
