Product Details

Fit:
MultiFIT Last: 97 - 100mm: The MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 97mm to 100mm eliminating the need for multiple last option (LV, MV).
FastFIT Instep: Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
Fully Heat Moldable
Flex:
Flex: 140: A very stiff flex for the most aggressive expert skiers.
Liner:
Intuition PowerFit Wrap BOA®: BOA liner increases adjustability and hold across the entire foot. Features stiffer foam with a full wrap design for added power and energy transmission. Completely heat moldable with pre-molded ankle pocket.
Ski/Walk Mode:
Powerlock Spyne: Rugged, precise and intuitive. The Powerlock Spyne walk mechanism allows for 50 degree range of motion when hiking and an unforgiving, powerful connection while skiing. The mechanism can also be adjusted to customize the forward lean of the boot between 10-17°.
Friction Free Cuff Pivot: An easy hinging cuff pivot designed to provide minimal resistance while in walk mode.
Buckles:
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 micro-adjustments.
2 Light Alloy Upper Buckles
Power Strap:
Elastic Cam Strap - One Piece: Increases performance and responsiveness by cinching tighter than a traditional power strap resulting in exceptional power transmission and precise handling.
Sole:
GripWalk ISO 23223 Outsoles: Removable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking.
Additional Features:
Integrated Tech Fittings: Tech fittings in the toe and heel are fully integrated into the shell injection, allowing for compatibility with both tech and DIN bindings.
