BOA® Fit System:
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.
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.
MultiFit™ Last:
The MultiFit™ Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 97mm to 100mm out of the box (and up to 104MM* with heat molding).
Powerlock Spyne:
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.
Integrated Tech Fittings:
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.
Grip Walk Outsoles:
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.
Fastfit Instep:
Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
Fully Heat-Moldable:
Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.
Friction Free Cuff Pivot:
An easy-hinging cuff pivot designed to provide minimal resistance while in walk mode.
Powerlite Shell:
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.
Booster Cam Strap:
Feel locked in like never before -- the Booster Cam Strap increases performance and responsiveness by cinching tighter than a traditional power strap resulting in exceptional power transmission and precise handling.
Micro-Adjust Buckles:
Dial in the fit of your boot by spinning the buckle clockwise, (tighten) or counterclockwise (loosen) for the perfect fit.
Harshmellow™ Insert:
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.
PowerFit Pro BOA® Tour:
All the features of the original PowerFit Pro Tour liner with the added performance and comfort of the BOA® closure system. Pre-molded and lasted with Ultralon heat-moldable foam. Featuring stiffer foam and a stiff, asymmetric tongue for added power and energy transmission, pre-molded ankle pockets, and a high-density power collar. Includes a tour notch at the back of the ankle for increased comfort and range of motion while hiking and skinning
Honeycomb Boot Board:
Stay Warmer, Longer. Traps heat and insulates like a down jacket. Retains heat 15% better than traditional boot board. Boot-fitter friendly
TRUST A PROFESSIONAL:
Before using your new boots, you must have an authorized K2 Ski retailer check your boot, binding, and sole setup. K2 Ski boot soles must only be changed by an authorized retailer.
