The ultimate splitboard boot from K2

Tired of long lift lines, uncomfortable boots, and slippery climbs? The K2 Aspect was designed specifically for backcountry skiing, with durability and performance in mind. Its sleek design allows you to conquer lines you’ve only dreamed of.

Outer boot
Introducing the Endo 2.0 construction – a boot design for flexibility and durability down to the last detail. Endo redefines construction with an innovative endo-skeleton made of urethane, replacing traditional layers. Unlike conventionally glued and sewn frames, the Endo structure can be flexed repeatedly and always bounces back to its original position and strength without compromising performance. This results in consistent flex and a boot that performs consistently across all conditions. For unparalleled grip and durability, the Vibram Mountaineer outsole ensures a secure hold in any situation. It is compatible with crampons and ideal for backcountry use. Additionally, the Harshmellow Pro insole provides superior cushioning and reduces vibrations at high speeds.

Liner
The liner features a high-density, thermoformable Intuition Pro Foam 3D Liner with internal and external J-Bars, providing a precise fit and superior performance suitable for professional use. Additionally, the liner is complemented by a 3D-molded EVA insole, ensuring plenty of comfort.

Lacing system
You can open or re-lace the liner at any time without having to open the outer lacing, thanks to the patented BOA Conda. The CONDA system is connected to the outer boot by a BOA cog and wraps around the liner to keep your foot firmly in place, focusing on heel and ankle support. You can choose how tight you want your liner laced and conveniently adjust it individually. Traditional lacing allows you to lace up the outer boot quickly and easily.
