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: 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: DIALED IN:
Precision fit with on-the-fly tightening and loosening for enhanced responsiveness, optimized pressure distribution, and reduced pressure points.
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 96mm to 104mm, eliminating the need for multiple last
options.
* Mindbender, Anthem, & Recon BOA® models range 97mm - 100mm
* Cortex BOA® models range 96-98mm
* BFC BOA® models range 100mm - 103mm (104mm with heat molding)
Fastfit Instep:
Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
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.
Powerfuse Spyne:
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.
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.
GripWalk 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.
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
Women's Adjustable Cuff:
Adjustable rear cuff support for Anthem boots that can be customized to fit with any calf shape.
Energy Interlock:
A rivet-free technology that integrates the cuff and shell, putting less stress on the boot’s material and produces a smoother, progressive flex.
Powerfit Pro Liner:
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.
GripWalk:
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.
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.
