K2 SpYne 90 Ski Boots

K2 SpYne 90 Ski Boots


Built with Extra Comfort and Forgiveness


The K2 SpYne 90 is the most forgiving men's all-mountain ski boot in the line, with a 102mm last to ensure a comfortable fit with our CushFit liner. Do not be fooled by the 90 Flex; this boot can more than hold its own all over the resort. The overall design helps deliver balanced ski performance and consistent turn shape across a wide range of terrain.



K2 SpYne 90 Ski Boots Features:


CushFit Intuition Liner
The CushFit liner utilizes a combination of standard open and closed cell EVA foam in a similar multi-layer construction to offer warmth, comfort, and performance right out of the box. Asymmetric Tongues enhance fit and ensure smooth flex initiation, while the Power Collar offers the upper cuff support you demand to tackle the whole mountain.


PowerClinch Strap
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.


Dual Cuff Alignment
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.


Alloy Buckles
6060 T6 Extruded Hardened Aluminum Alloy built with a minimalist lightweight design.


K2 Ski Boot Technologies



ENERGY INTERLOCK



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.





SYNCHRO INTERLOCK



Built on the Energy Interlock design platform, the Synchro Interlock enables the simultaneous release of both an internal wedge and the Interlock. When released, the Synchro Interlock delivers greater fore and aft range of motion for more efficient touring. Engaging the wedge and Interlock functionally creates an all-mountain boot, with 100% of the flex index and uncompromised downhill performance. This user-friendly design can be locked or released with the flick of a ski pole for on-the-go efficiency.




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.





FIT LOGIX



Fit Logix is the bridge between your foot and the exterior features of our ski boots. Fit Logix includes the combination of a diverse last offering (97mm, 100mm, and 102mm), 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 INTUITIONTM liners, to deliver performance, comfort, and a customized fit.
