Catering to the expert level lady shredder, the K2 Spyre 110 Ski Boots have a powerful flex that combines race boot performance with more all-mountain comfort. With a 97mm last, the Spyre 110s features a performance low volume fit with an average instep height and their fully heat moldable PrecisionFit Intuition® liners cap things off for a level of comfort that's previously unheard of in high-performance ski boots. If you aspire to ski at the highest level but are tired of mitigating pain every time you buckle your boots, the K2 Spyre 110 Ski Boots are worth a serious look.
Last: 97 mm – K2's low volume (LV) last that provides improved performance for those with narrower width, lower instep height feet.
Flex: 110 – Perhaps the perfect flex for all-mountain advanced and expert skiers who don't need or want race boot level stiffness.
PrecisionFit Intuition® Liner – K2's premium level liner uses traditional foams around the ankle for superior response and fully heat moldable Intuition® foam around the foot for a custom fit.
Cuff / Shell – Polyurethane
Energy Interlock – A rivet-free technology that integrates the cuff and shell of the boot. The Interlock stretches when the boot is flexed forward, and the energy is released throughout the turn, creating a smoother, more natural flex than riveted designs.
PowerFuse 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 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.
Forgiving Shell Materials – SpYne construction allows the use of more forgiving materials at the cuff / shell junction, making entry and exit of the boots easier.
Power Wedge – A removable spoiler for adjustable forward lean angle from 12 to 14 degrees.
Cuff Alignment Index – Dual sided cuff alignment for +/- 2 degrees of cuff alignment.
6060-T6 Light Alloy Buckles – Extruded hardened aluminum alloy build with a minimalist lightweight design.
