K2 BFC 120 Ski Boots

Designed for experienced skiers who refuse to choose between power and comfort, the K2 BFC 120 embodies a balanced approach to high-end alpine ski boots. With a flex rating of 120 and a roomy fit, they’re designed for advanced to expert skiers who tackle the slopes with dedication, without sacrificing comfort at the end of the day. The thermoformable construction and BOA® Fit System make this a boot designed for lasting performance, from the first chairlift ride to the last turn.

A 120 flex with a roomy fit: the perfect combination for the discerning skier

The K2 BFC 120’s 120 flex clearly positions this boot in the advanced to expert skier category. This flex rating ensures direct energy transfer to the ski while maintaining a certain degree of forgiveness, making it suitable for both challenging on-piste runs and long days on the mountain. The 103 mm last provides a roomy fit: skiers with wide feet or high insteps will enjoy support without pressure points, without compromising on precision. MultiFit™ Last technology enhances this adaptability by allowing the shell to adjust to a wide range of foot shapes.

Full thermoforming and CushFit Pro liner: customizable comfort

The TPU shell and polypropylene collar are fully thermoformable, allowing a professional bootfitter to precisely mold the boot to the foot’s shape. This ability to customize in a workshop is a real advantage for skiers whose feet don’t fit into a standard mold. The CushFit Pro liner, featuring Ultralon foam, ensures even support and thermal comfort ideal for long sessions. The entire construction thus promotes a custom fit without requiring major structural modifications.

BOA® closure system and aluminum buckles: precision and convenience in tightening

The K2 BFC 120’s tightening system relies on several complementary elements worth detailing:

  • BOA® Fit System on the lower shell: precise and uniform foot adjustment with a simple turn of the dial, without the need to re-buckle by hand.
  • 4 micro-adjustable aluminum buckles: these allow for fine, gradual adjustment of support across the entire boot.
  • 40 mm Velcro Power Strap: It reinforces shin support and improves the transfer of force to the ski.
  • FastFIT Instep: makes it easier to put the boot on by providing a wider opening for the foot.
  • Apres Mode 2.0 with 50 degrees of range: the built-in walking mode releases the cuff for natural movement off the skis.

GripWalk sole and binding compatibility: traction and versatility

The GripWalk® outsole (ISO 23223 standard) offers significantly improved traction on slippery surfaces, whether on access trails or on mountain hut terraces. Unlike a traditional ISO 5355 alpine outsole, the GripWalk outsole features a flexible rubber zone that facilitates natural walking. This boot is compatible with modern alpine bindings equipped for the GripWalk standard, making it a versatile option for skiers who want to move freely both on and off their skis.

The K2 BFC 120 is designed for the experienced skier looking for a ski boot that combines a generous fit, advanced customization, and precise lacing thanks to the BOA® Fit System. Whether on red or black runs, at the resort, or on a Nordic ski tour, they deliver the responsiveness expected from a 120 flex with the comfort of a construction designed to last all day.
