The Katharina is a hybrid of a classic Italian Alp approach shoe and a modern athletic sneaker. This particular pair finds ROA collaborating with British designer Jean-Luc A. Lavelle and his eponymous brand, as the shoe is executed in a neutral navy and black color combination. Technical anti-abrasion nylon is used throughout to increase overall durability, while a custom treaded Vibram sole provides superior traction and support on rough terrain.
