Built with integrated heel welts, a leather upper, an insanely grippy Vibram outsole, and a bevy of other features, the K2 Snowboards Aspect Snowboard Boot is designed to keep feet happy and secure during long days spent in the backcountry. The exterior of the Aspect features a rugged, waterproof leather upper and traditional laces for reliable protection and a fit that's in our hands. The thermo-moldable Intuition SpaceHeater liner conforms to the foot, and BOA Conda liner lacing locks in the fit quickly without messing with internal laces. Furthering its responsiveness, the Endo 2.0 urethane skeleton construction provides a precise, engineered flex that stays consistent throughout the life of the boot. Specifically designed for boarders who climb to access their lines, the Vibram Mountaineer rubber outsole has a traditional lug design and is crampon-compatible to safely get to the top of technical ascents.
