The BOA^® Fit System, provides a performance fit engineered to enhance feel, and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise micro-adjustments.

Provides micro-adjustable, precision fit and quick release, with quality and durability guaranteed. The BOA dial platform features a breakaway design engineered to eject the dial cartridge upon severe impact without damaging the system, allowing skiers to pop the dial back into the bayonet midmountain. In the unlikely event that the system is broken, it can be easily repaired and replaced.

Precision fit with on-the-fly tightening and loosening for enhanced responsiveness, optimized pressure distribution, and reduced pressure points.

Connected fit designed to uniformly wrap the foot and minimize downward pressure, increasing heel lock-down for improved power and edge-to-edge control.

Engineered for confidence and built to withstand rugged terrain and inclement weather, BOA® dials and laces deliver extreme durability. Bayonet and cartridge system ensures continued operation, even after heavy impacts.

Pre Molded and Lasted with Ultralon heat moldable foams. Features an asymmetric tongue, pre molded ankle pockets, and a medium density collar & foam package yielding performance with added comfort.

Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.

K2’s highest-performance shell design, utilizing shell walls of varying thicknesses and four different types of TPU to provide the ultimate combination of light weight and responsiveness.

A rear co-injected “Y” shaped support that adds strength and power to the Energy Interlock in order to maximize fore/aft flex efficiency and lateral stiffness for responsiveness in every type of terrain.

A rivet-free technology that integrates the cuff and shell, putting less stress on the boot’s material and produces a smoother, progressive flex.

Soft or rigid inserts in the heel of all the boots with BOA® fit system allow the rider to customize the feel, and responsiveness depending on personal preference; softer insert (blue) for extra damping, or a more rigid insert (grey) for improved power transfer.
