SpYre 100 Ski Boots give you a slightly softer 100 flex but include all the performance features of the stiffer SpYne 110. Designed to deliver support, fit and rebound out of the turn while still enabling smooth and consistent turn initiation for less aggressive skiers. With replaceable outsoles and a padded midgrip, the SpYne is designed with long lasting performance and durability in mind. This is a great boot for women who ski hard all day but value comfort and a smooth style over heroics.
100 mm last
Flex Rating: 100 - A slightly softer (but still stiff) flex ideal for advanced to expert skiers
LuxFit INTUITION® Liner - 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 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.
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.
Dual Cuff Alignment Index - Adjust by +/- 2.2 degrees on both 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.
Alloy Buckles - 6060 T6 Extruded hardened aluminum alloy built with a minimalist lightweight design
35 mm Power strap
Replaceable Outsoles - Dual-injected Thermo Plastic Rubber (TPR) with Thermo Plastic Utrethane (TPU) increases the life of your boots and provides secure footing whether walking on rock, ice, or stairs.
Padded Mid-Grip - Dual-injected Thermo Plastic Rubber (TPR) for added grip and traction while walking on rocks or riding on snowmobiles
Energy Interlock™ - A rivet-free technology for integrating the cuff and shell, 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 less stress on the boot material but also produces a smoother, more efficient load transfer, delivering a more natural flex and dynamic performance in all conditions.
Powefuse SpYne™ - 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 and sustained performance and responsiveness in all terrain. Because of the SpYne, K2 is able to optimize materials in the cuff and shell, eliminating excessive vibration in rough terrain.
Fit Logix™ - Fit Logix™ is the bridge between your foot and the exterior features of K2 ski boots. Fit Logix includes the combination of diverse last offerings (97 mm, 100 mm, and 102 mm), a navicular punch that is built into the mold of our boots to alleviate pressure during ankle flexion, as well as an advanced collection of K2 INTUITION® liners, to deliver performance, comfort, and a customized fit. In addition, thanks to the strength of the PowerFuse SpYne, K2 is able to use a softer shell material while maintaining flex, meaning the boots are also easier to get on and off, perfect for those cold mornings in the parking lot.
