The BOA® Fit System delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.

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.

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 performance-oriented walk mode designed for ski touring that offers a 50-degree range of motion. When in ski mode, Powerlock Spyne provides a powerful and secure connection for uncompromised downhill performance.

Tech fittings in the toe and heel are fully integrated into the shell injection, allowing for compatibility with both tech bindings and alpine DIN bindings.

Includes a tour notch at the back of the ankle for increased comfort and range of motion while hiking and skinning.

The sole-binding system for better walking comfort and top skiing performance. GripWalk contains of a new co-polymer sole with rocker profile. The convex shape and ribbed tread of the rubber add a lot of walking comfort and provide a much better grip. Still, integrated pads made of stiff and rigid materials, enable great power transmission and more precise release function of the binding. GripWalk soles are the perfect tuning parts designed for selected premium ski boots and bindings.
