Cuff / Shell – Polyurethane
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.
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.
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.
Dual Adjustable 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.
Power Wedge – A removable spoiler for adjustable forward lean angle from 12 to 14 degrees.
