The Calyx™

Introducing the Calyx™, Purple Mountain Observatory’s debut footwear silhouette, designed and developed in collaboration with Vibram. A modern interpretation of the classic camp shoe, the Calyx™ is built for those moments between effort and recovery. 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 or layering.

The Vibram Grivola outsole delivers lightweight grip with its Vibram Megagrip compound, durability, and all-weather traction, making it equally suited to the trail, forest, dry or wet and anything in between.

Returns can be made within 14 days from receipt of order. Items must be unworn and returned in original packaging.
