Last: 100 mm – K2's 100 mm last is perfect for most average width, average instep height feet.
Custom Thermo Shell – The shell can be molded to accommodate wider or irregular foot shapes through a heat molding process. 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: 100 – A stiff flex most suitable for advanced to expert skiers.
LuxFitPRO Liner – This 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 Tour 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.
Moldable Asymmetric Tongue
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.
Energy Interlock – A rivet-free technology that integrates the cuff and shell of the boot. The Interlock stretches when the boot is flexed forward, and the energy is released throughout the turn, creating a smoother, more natural flex than riveted designs.
Dual Cuff Alignment – Dual sided cuff alignment for +/- 2 degree of cuff adjustment.
Forward Lean – 14° / 12° with Power Wedge
40 mm Velcro Powerstrap
Replaceable Outsoles with Padded Mid-Grip
