Last: 97 mm – Low volume performance last best suited to those with narrower, low volume feet.

Custom Thermo Shell – The shell can be heat molded, punched, ground and customized with your favorite boot fitter for optimized comfort and performance. The shell can be widened up to 6 mm with this process.

Asymmetrical Toe Box – K2 matches the toe box to the natural curvature of your toes for a more precise and comfortable fit.

Navicular Punch – A bump is pre-formed in the navicular area of the medial ankle where many skiers experience pressure.

Flex: 130 – As stiff as freeride boots get, the 130 flex is just right for driving the biggest skis at the highest speeds.

PecisionFit Tour Light Liner – This premium 100% heat-moldable liner is lasted for precise "out-of-the-box" fit and 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 Notches – Natural flex and optimized range of motion when in walk mode.

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, K2 is able to optimize materials in the cuff and shell, eliminating excessive vibrations in rough terrain.

Shell – Polyurethane

Cuff – Polyurethane

Dual Cuff Alignment – Dual sided cuff alignment for +/- 1 degree of cuff adjustment.

Forward Lean – 14° / 12° with Power Wedge

Synchro Interlock™ – Built on the Energy Interlock design platform, the Synchro Interlock enables the simulatenous release of both an internal V-notch wedge and the Energy Interlock. When disengaged, the upper cuff is unlocked from the lower shell for fore and aft mobility by removing the wedge and opening the v-notch in the shell which increases the forward flex for more efficient movement. When engaged, the Synchro Interlock™ creates an all-mountain boot, with 100% of the flex index and uncompromised downhill performance.

4 Aluminum Micro-Adjustable Lightweight Buckles

40mm Velcro Powerstrap

Replaceable Outsoles with Padded Mid-Grip

Integrated Tech Fittings – Fully integrated into the shell injection instead of just the outsole pads. This makes these outsoles compatible with both alpine and tech bindings.

Vibram® Rockered Outsoles Available Separately – Vibram® ISO 9523 rubber touring sole upgrade available for added grip, traction and security when climbing or hiking more technical terrain.
