The K2 SpYne 110 is a high-performance all-mountain boot for those wanting a more forgiving 110 flex. With a rear co-injected “Y” shaped design that adds strength and power to the Energy Interlock, the PowerFuseSpYne 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 Energy Interlock gives the boots life and power. 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. The key is being able to optimally capture, store and release this energy while preventing high levels of stress. The larger surface area of the Energy Interlock design produces lower pinpoint stress levels, resulting in a smoother load transfer - ideal for maximizing performance across inconsistent and variable terrain and conditions. On the other hand, the nature of a riveted design causes greater stress around the rear rivets, delivering a blocky, inconsistent flex.
The LuxFitINTUITION® heat-moldable linercombines 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 LuxFitINTUITION® 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.
The combination of the PowerFuse SpYne, Energy Interlock and LuxFitINTUITION® liner enables this boot to absorb vibrations stemming from snow and terrain inconsistencies, while ensuring optimal energy delivery to the ski. With fully replaceable outsoles and a padded midgrip, the SpYne 110 is designed to withstand an endless all-mountain beating.
