The upper material is made of high-quality suede leather with textile inserts, making the shoe very durable. The textile lining and Ortholite insole provide high wearing comfort, and the insole can be replaced with your own 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. This includes the extended lacing that reaches into 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.
