K2 Spyre 110 LV Ski Boot - Women's: S1419011 : The K2 SpYre 110 ski boot, featuring a women’s specific last, is the most aggressive, highest performing, stiffest boot in the collection. It is made for expert women skiers with the Energy Interlock, PowerFuse SpYne, and molded and lasted PrecisionFit INTUITION® liner. Now offered in a 97mm (LV) and 100mm last so the width and shape of your foot no longer dictates what boot you wear.
Energy Interlock, PowerFuse SpYne, Dual Cuff Alignment, Replaceable Outsoles, Padded Mid-Grip, 35mm Velcro Powerstrap
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.
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.
Our premium, heat-moldable liner, the PrecisionFit INTUITION®, is molded/lasted to deliver a precise “out-of-the-box” fit, minimize “dead spots,” and optimize power transfer between the liner and shell.
Cuff alignment index
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.
Power wedge forward lean
The Power Wedge is a removable spoiler for accommodating varying calf shapes and adjusting your desired forward lean angle. The Power Wedge increases forward lean by two degrees, moving the angle from 12 to 14 degrees.
