The upper material is made of high-quality suede leather with textile inserts, making it very durable. For high wearing comfort, the textile lining and the textile insole, which can be replaced with your own insert if needed, provide excellent support. 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 profiled outsole guarantees optimal traction. The perfect companion for your adventures in the wilderness.
