The upper material is made of high-quality suede leather with textile inserts, making the shoe very durable. The textile lining and the Ortholite insole provide high wearing comfort, which can be replaced with your own insole if needed. The Add technology (Anatomically Directed Design) is a combination of various systems based on the asymmetry of the feet to ensure a perfect fit. Among other features, this includes the extended lacing that goes down to the toe area. Additionally, the VIBRAM outsole guarantees optimal traction, and the rubber inserts protect against stones and roots. The perfect companion for your adventures in the wild.
