Own Every Turn. Conquer Every Line. Cortex 130 Zonal BOA®. Built to Perform.

BOA® Fit System on the Cuff and Shell:
The BOA® Fit System shell 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.
The BOA® cuff single cable design allows the tension to self equalize always giving a consistent pressure to the shin. The improved wrap allows for better power transmission and improved comfort even at high tension

H+i1 DIAL:
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.

BOA® FIT SYSTEM: DIALED IN:
Precision fit with on-the-fly tightening and loosening for enhanced responsiveness, optimized pressure distribution, and reduced pressure points.

BOA® FIT SYSTEM: LOCKED IN:
Connected fit designed to uniformly wrap the foot and minimize downward pressure, increasing heel lock-down for improved power and edge-to-edge control.

BOA® FIT SYSTEM: CONFIDENT:
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.

True LV Fit:
All new low volume last featuring our narrowest heel and ankle while maintaining a little room in the forefoot and toe box for an all day performance fit.

Fastfit Instep:
Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.

About K2

K2 is the original American Ski and Snowboard Brand, founded in 1962 in Washington State. The brand continued to pioneer by expanding into snowboards in 1987 and was the first brand to specifically engineer products for women starting in 1999; our Women’s Alliance™. Today we are resetting the K2 brand for the future, one that builds on this legacy to reposition as the industry leader.

Skiing is who we are

We were established almost 75 years ago by John Monod, a Swiss mountain guide and ski instructor. Quality outdoor gear is what our brand was built upon since 1949.
