K2 Waive 8 2026

The K2 Waive is a purpose-built splitboard boot designed for ambitious backcountry missions and long days in changing mountain conditions. Its stiff 8/10 flex delivers dependable support and stability on descents, while the heat-moldable Intuition Pro Foam liner helps create a precise, comfortable fit.

On the ascent, the dedicated walk mode—activated by a BOA dial—promotes a longer, more natural stride. A crampon-compatible Vibram V5 outsole adds confident traction, while Harshmellow damping and Spaceheater technology help reduce impact and retain warmth. It suits splitboarders who prioritize uphill efficiency, downhill control and reliable all-day comfort.
