2027 K2 BFC BOA 100 Men's Ski Boots

The BFC 100 BOA is for skiers with wider feet who want an easy-to-wear boot that can still handle the whole mountain. The 100 flex balances comfort and support, and K2's high-volume MultiFit last, built around the BOA system, gives wider feet room to relax.

The BOA Fit System wraps your foot evenly with a micro-adjustable dial, and Hands Free Entry with a softer Fastfit Instep makes getting in and out simple. The TPU shell and PP cuff are fully heat-moldable for a custom fit, the Powerfuse Spyne adds a Y-shaped rear support for better fore-aft and lateral response, and the 50 mm adjustable calf fits a wider range of legs. Inside, the CushFit Comfort liner adds extra foam in key areas, a 40 mm Velcro strap snugs the cuff, and Apres Mode 2.0 unlocks the cuff for 50° of range when you're walking.

GripWalk soles (ISO 23223) add grip on the walk and work with GripWalk-compatible bindings. It's a boot for comfortable laps from first chair to the last run with friends.

Best for beginner to intermediate skiers with wider, higher-volume feet who want a comfortable BOA boot with a walk mode.
