Lasted for precise "out-of-the-box" fit the LuxFit Tour also includes heat-moldable Asymmetric Tongues to reduce shin bang and ensure smooth, precise flex initiation.

Shell Materials & Design

Energy InterlockA 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 SpYneA 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, K2 is able to optimize materials in the cuff and shell, eliminating excessive vibrations in rough terrain.

Stance

Cuff Alignment IndexDual sided cuff alignment for +/- 2˚ of cuff adjustment.
