K2 SpYne 110 LV Alpine Boots

A rivet-free technology that locks the cuff and shell in both the forward and aft direction. This fundamental technology gives the boots life and power ideal for all-mountain and freeride skiing where you encounter a wide variety of conditions and terrain. When the boot flexes forward, the Interlock stretches, creating a buildup of energy. This not only puts lower stresses on the boot material but also produces a smoother, more efficient load transfer, delivering a more natural flex and dynamic performance in all conditions.

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.

The LuxFit INTUITION® heat-moldable liner combines the performance and fit of a traditional PVC liner with the benefits of strategically placed ULTRALON EVA foam. Lasted for a 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.

Dual-injected Thermo Plastic Rubber (TPR) with Thermo Plastic Urethane (TPU) increases the life of your boots and provides secure footing whether walking on rock, ice, or stairs.

Duel Injected Thermo Plastic Rubber (TPR) for added grip and traction while walking on rocks or riding on snowmobiles.

Extra wide, strong, and powerful cam-lock PowerClinch strap featured on the SpYne 130. Durable Velcro Powerstraps in varying widths for support and strength on all other models.

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.
