A modern solution to the camp shoe; the extension of Purple Mountain Observatory and Vibram's passion for nature and the need to explore.

Engineered through Vibram's advanced StratX formula, the Calyx's seamless waterproof upper is sculpted from a single sheet of special rubber, eliminating the need for traditional stitching. The Vibram Grivola sole delivers lightweight grip with it's Megagrip compound, making it equally suited to the trail, forest, both dry and wet, and everything that comes in-between.
