K2 BFC 120 BOA® Men’s Ski Boots 2026

The K2 BFC 120 BOA® Men’s Ski Boots are high-volume, 120-flex all-mountain boots that combine micro-adjustable BOA® fit, a roomy 103 mm last, and a fully heat-moldable shell so advanced skiers can ski hard without sacrificing comfort.

Comfort-First Fit Meets Real All-Mountain Power

• High-volume 103 mm MultiFit™ last: A generous high-volume shell and 103 mm forefoot width give wide feet the space they need, easing pressure on toes and instep while still holding you securely for confident edge control.
• 120 flex for advanced skiers: A stout 120 flex offers strong, responsive support for aggressive all-mountain skiing, so you can drive modern skis at speed without feeling like the boot is folding underneath you.
• BOA® lower shell fit system: The BOA® Fit System wraps the lower foot evenly with a quick turn of the dial, eliminating hot spots from overtightened buckles and letting you fine-tune fit on the fly—right on the lift.
• CushFit Pro liner comfort: The CushFit Pro liner uses supportive Ultralon foam to blend plush, out-of-the-box comfort with the structure you need for precise steering, then molds to your foot shape over time.
• Fully heat-moldable shell and cuff: Both the TPU shell and PP cuff can be custom molded, giving bootfitters plenty of room to solve tricky fit issues and dial in long-day comfort.
• Apres Mode 2.0 walk function: A lever on the spine unlocks the cuff for up to 50° of motion, making it much easier to walk from the car, around the base area, or through the parking lot at the end of the day.
• GripWalk® outsoles: Pre-installed GripWalk® soles improve traction and natural stride while staying compatible with GripWalk-approved alpine bindings for reliable power transfer.
• Hands Free Entry & FastFit instep: A softer instep zone and dual-material overlap make it easier to slide in and out of the boots—especially welcome on cold mornings.

Ideal For

The BFC 120 BOA® is ideal for advanced to expert skiers with wider, higher-volume feet who want real performance without a race-boot squeeze. It’s a great choice for all-day resort skiing on groomers, mixed snow, and the occasional park lap, especially if you value step-in ease and a customizable, comfort-focused fit.
