Component Breakdown
True-Form Last
True-Form last — women's-specific last geometry tuned for female foot shape and volume. Better out-of-the-box fit for women skiers, less forefeet pressure and heel hold issues common with men's-lasts on women's feet.
True-Align Geometry
True-Align geometry keeps you balanced and powerful through every turn — balanced stance positioning that delivers efficient energy transfer from the legs through the boot to the ski. Tuned for women's center of gravity.
Zonal BOA® Fit System — Even Wrap
Zonal BOA® Fit System wraps evenly for a custom feel — separate upper and lower zones for independent tightening. Micro-adjustable closure delivers precise, secure fit across the entire boot.
Women's-Specific Shell
Women's-specific shell designed around the female calf and ankle geometry — better forward flex, reduced bulk around the cuff. Built to accommodate women's specific leg proportions without distortion.
Women's-Specific Liner
Women's-specific liner — shaped for women's calves and ankles with reduced volume and proper geometry for female foot shape. Heat-moldable for custom fit.
GripWalk Outsole
GripWalk outsole provides safe and comfortable walking thanks to its curved rubber shape. Compatible with all GripWalk bindings (ISO 23223 standard) and traditional alpine bindings (ISO 5355) — versatile compatibility.
ISO 5355 Standard Compliance
ISO 5355 standard compliance — compatible with all traditional alpine ski bindings. The classic alpine boot sole geometry fits any ISO-compliant binding on the market.
