Ski boots are sized in Mondo point (cm foot length) — primary measurement for ski boot fit. Unisex sizing — US Men's and US Women's equivalents shown alongside. Standard conversion: Women's = Men's + 1 size. 10 sizes from Mondo 22.5 through 31.5 in half-Mondo steps — widest size range in the K2 ski boot lineup (covers freestyle skiers from petite to tall). Compatible with all standard alpine ski bindings (ISO 5355 / GripWalk soles).
Component Breakdown
FL3X 3-Piece Construction
FL3X 3-piece shell construction — separate upper cuff, lower shell, and tongue for maximum range of motion and flex tuning. The 3-piece design is the standard for freestyle ski boots, allowing aggressive forward flex without distortion.
Lightest Freestyle Boot in the Lineup
The lightest freestyle boot in the K2/FL3X lineup — minimal weight for park laps, switch tricks, and aerial maneuvers. Built for skiers who want to feel the ski underfoot without boot weight holding them back.
FL3X Freestyle Engineering
Designed specifically for freestyle skiers who throw anything at the mountain — park laps, pipe, big air, switch tricks, urban features. Built to handle the abuse of freestyle skiing with responsive energy transfer.
Premium Closure System
Premium closure system for secure, custom fit — micro-adjustable for fine-tuning fit and pressure distribution. Keeps the boot locked in during hard landings and aggressive turns.
Performance Liner
Performance liner delivers precise foot wrap and responsive energy transfer. Heat-moldable for custom fit — conforms to individual foot shape over time. Built for the demands of freestyle skiing.
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 for any binding setup.
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.
