Product Info

Reach the peak of ski boot versatility with a pair of K2 Pinnacle 110 Ski Boots. Featuring honest-to-goodness alpine boot performance with K2 s Synchro Interlock walk mode and integrated tech fittings, the Pinnacle 110 lets you enjoy both sides of the mountain in one boot. You'll be free to catch early morning freshies on the lift and switch to touring when things get tracked out later in the day. The versatile 110 flex offers a great compromise between control and flexibility while the 100mm forefoot width is ideal for skiers with average width feet.

Product Details


Last: 100 mmK2's 100 mm last is perfect for most average width, average instep height feet.

Custom Thermo ShellThe 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 PunchA bump is pre-formed in the navicular area of the medial ankle where many skiers experience pressure.


Flex: 110Moderately stiff, suitable for advanced to expert skiers.


LuxFit Tour Light LinerThis 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.

Shell Materials

PowerFuse SpYneA 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.




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

Forward Lean14° / 12° with Power Wedge

Ski/Walk Mode

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

Power Strap

40 mm Velcro Powerstrap


Replaceable Outsoles with Padded Mid-Grip

Integrated Tech FittingsFully 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 SeparatelyVibram® ISO 9523 rubber touring sole upgrade available for added grip, traction and security when climbing or hiking more technical terrain.
