The upper material is made of high-quality suede leather with textile inserts, making it very durable. The textile lining and the textile insole, which can be replaced with your own insert if needed, ensure high wearing comfort. 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 goes down to the toe area. Additionally, the VIBRAM Sticky sole guarantees optimal traction, and the rubber inserts provide protection against stones and roots. The perfect companion for your adventures in the wilderness.
