K2 Mindbender 120 BOA® Men’s Ski Boots 2026

The K2 Mindbender 120 BOA® Men’s Ski Boots 2026 are powerful hybrid freeride/touring boots that pair a stiff 120 flex, lightweight Powerlite shell, and BOA® Fit System with tech fittings and a huge walk range for skiers who want one boot for resort and backcountry.

Tour-Ready Construction, Big-Mountain Control

• Powerlite shell with 120 flex: K2’s Powerlite TPU shell uses varied wall thickness to keep weight low while delivering the strong 120 flex you need to charge big lines, variable snow, and wide modern skis.
• Micro-adjustable BOA® lower shell: The BOA® Fit System wraps the lower foot evenly with a twist of the dial, eliminating buckle hot spots and letting you fine-tune tension on the skin track, at the top, or on the chairlift.
• MultiFit™ 100 mm last, medium volume: A 100 mm medium-volume last with MultiFit™ design accommodates a wide range of foot shapes, then customizes further with full shell and cuff heat molding.
• Precisionfit Pro Tour liner: A laceable, Ultralon®-foam liner with an asymmetric tongue, power collar, and flex notch combines touring mobility with locked-in downhill control.
• Powerlock Spyne walk mode: The Powerlock Spyne walk mechanism unlocks up to 50° of cuff range of motion for efficient touring, then locks solidly for uncompromised downhill performance.
• Integrated tech fittings: Fully integrated tech fittings at the toe and heel make the Mindbender 120 BOA® compatible with tech/pin bindings as well as GripWalk-compatible alpine bindings.
• Modular Honeycomb bootboard: A heat-trapping honeycomb bootboard with hard and soft inserts improves warmth and lets you tune damping and response underfoot.
• GripWalk® soles: Rockered GripWalk® ISO 23223 soles boost traction and walking comfort around the parking lot, bootpack, or hut, while maintaining reliable binding interface.

Ideal For

Built for advanced freeride skiers who split time between the resort and the backcountry, the Mindbender 120 BOA® is for riders who want one boot to tour, charge steeps, ski powder, and rip groomers—all with a precise, BOA®-dialed fit.
