Whether it’s trudging through the village to après, or hiking that ridgeline for one last run, an efficient walk mode always comes in handy. The Pinnacle 100 ski boot is the newest, softest flexing member of the Pinnacle bloodline and features the same Synchro Interlock that makes the 130 and 110 so adept at both skiing and walking. The lasted CushFit Tour INTUITION® liner provides all-day comfort and warmth, while replaceable DIN-Compatible Outsoles, Padded Mid-Grip and 45mm Velcro PowerStrap deliver lasting utility and durability.


  • 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% of 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.
  • The CushFit liner utilizes a combination of standard open and closed cell EVA foam in a similar multi-layer construction to offer warmth, comfort, and performance right out of the box. Asymmetric Tongues enhance fit and ensure smooth flex initiation, while the Power Collar offers the upper cuff support you demand to tackle the whole mountain.
  • 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 - Adjust +/- 2.2 degrees on 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.
  • Dual Injected Thermo Plastic Rubber (TPR) for added grip and traction while walking on rocks or riding on snowmobiles.
