Last: 102 mm – A wide last for comfort or wider feet

Flex: 110 – Pretty stiff, and suitable for advanced skiers

LuxFit Tour Intuition® Liner – The LuxFit Intuiton® heat-moldable liner combines the performance and fit of a traditional PVC liner with the benefits of strategically placed Ultralon EVA foam. Lasted for precise "out-of-the-box" fit the LuxFit Intuition® also includes heat-moldable Asymmetric Tongues to reduce shin bang and ensure smooth, precise flex initiation. The Power Wedge and Power Collar offer varied forward lean and the upper cuff support needed for taking advantage of challenging conditions.

Tour Flex Notch – These notches are strategically placed at the main hinge points, allowing the liner to flex naturally with the ankle and shell when in walk mode, improving range of motion and touring efficiency.

Shell / Cuff – Polyurethane

Forgiving Shell Materials – Use of the PowerFuse SpYne allows K2 to retain fore / aft stiffness while using softer materials around the throat of the boot - this means easier entry and exit for you.

PowerFuse SpYne – A rear co-injected “Y” shaped design that adds strength and power to the Energy Interlock, the PowerFuse SpYne maximizes fore/aft flex efficiency and lateral stiffness for sustained performance and responsiveness in all terrain. Because of the SpYne, we are able to optimize materials in the cuff and shell, eliminating excessive vibrations in rough terrain.

Dual Cuff Alignment Index – Adjust by +/- 2.2 degrees on both medial and lateral sides for a total range of 4.4 degrees. This enables adjustment to the lower leg angle for maximum comfort and performance.

Power Wedge / Forward Lean – The Power Wedge is a removable spoiler for accommodating varying calf shapes and adjusting your desired forward lean angle. The Power Wedge increases forward lean by two degrees, moving the angle from 12 to 14 degrees.

Synchro Interlock – Built on the Energy Interlock design platform, the Synchro Interlock enables the simultaneous release of both an internal wedge and the Interlock. When released, the Synchro Interlock delivers greater fore and aft range of motion for more efficient touring. Engaging the wedge and Interlock functionally creates an all-mountain boot, with 100% the flex index and uncompromised downhill performance. This user-friendly design can be locked or released with the flick of a ski pole, for on-the-go efficiency.

Alloy Buckles – 6060 T6 Extruded hardened aluminum alloy built with a minimalist lightweight design

35 mm Power strap

Integrated Tech Fittings – Tech fittings are fully integrated into the shell injection, instead of just the outsole pods. This Design guarantees greater strength, improved torsional stiffness, durability, and makes the outsoles compatible with both DIN - alpine and tech bindings.

Padded Mid-Grip – Dual-injected Thermo Plastic Rubber (TPR) for added grip and traction while walking on rocks or riding on snowmobiles.

Replaceable DIN Compatible Soles – Thanks to our Integrated Tech Fittings, our replaceable outsoles are all DIN-compatible, so you no longer have to switch outsoles to accommodate your various binding setups.
