The upper material is made of high-quality nubuck leather with textile inserts, making it very durable. The textile lining and the Ortholite Hybrid Plus insole provide high wearing comfort, which can be replaced with custom insoles if needed. The Add technology (Anatomically Directed Design) combines 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 thick rubber edge offers protection against stones and roots. The perfect companion for adventures in the wilderness.
