Standard conversion: Women's = Men's + 1 size (ski boot convention). 6 sizes from Mondo 22.5 through 27.5 in half-Mondo steps. Compatible with all standard alpine ski bindings (ISO 5355 / GripWalk soles).
Component Breakdown
True Low-Volume Fit (LV)
True low-volume fit — narrower last shape for skiers with narrower feet. Better out-of-the-box fit for women skiers, less forefeet pressure and heel hold issues common with wider lasts.
Approachable Flex 95
Approachable Flex 95 — softer than the Cortex 105 (95 vs 105), designed for progressing female skiers. "Confidence on every descent" without the punishing stiffness of race-level boots. Perfect for the journey from intermediate to advanced.
BOA® Fit System
BOA® Fit System with micro-adjustable dial delivers precise, custom fit. Secure, even pressure distribution across the foot. Easy in/out — no wrestling in the parking lot.
Multizone Dual Core
Multizone Dual Core — Poplar + Beech with tapers between the insert packs for a more forgiving flex. Tuned for women's progression and responsiveness.
Elite Fit Liner
Elite Fit Liner delivers precise foot wrap and responsive energy transfer. Heat-moldable for custom fit — conforms to individual foot shape over time. Premium construction for the high-output skier.
SuperDrive™ ADV Sintrured Base
SuperDrive™ ADV sintrured base — combines the durability of extruded with the hardness of sintered. Higher pressure and temperature in manufacturing creates surface hardness near most sintered bases — more durable when jibbing and ripping while retaining low maintenance.
Classic Cuff Construction
Classic cuff construction with traditional two-piece overlap design — reliable forward lean and efficient energy transmission. Direct power transfer for the progressing skier.
