Brand new, unused. This rare color is very cool, but I'm selling it due to circumstances. Size is 26.5. Product Description: Thanks to cutting-edge manufacturing technology, a sporty and flexible hiking shoe has been created, suitable for multi-day trips, trekking, and fast-paced mountain hiking. The Ducan High GTX® Men, featuring MAMMUT Flextron Technology, which integrates a spring-loaded steel sole into the midsole, prevents foot distortion and provides excellent vertical support, allowing for more efficient energy consumption during hiking and mountaineering. Ensuring the natural movement of the foot with MAMMUT Georganic 3D Technology, this shoe combines a geometric, dynamic design with a cut that naturally conforms to the foot. It also features asymmetrical lacing, a mono-tongue construction for single-sided entry, and an excellent fit achieved through an anatomically based shoe last. With a specially designed vibram® sole, the Ducan High GTX® Men provides reliable grip even on uneven terrain in the great outdoors and in rugged mountain areas. • Sewing pattern: Basic • Flex index: A6 • Lacing system: Asymetric • Last index: backpackingTech • Weight UK 8.5: 545 g Materials & Technology • Material: Double Layer Engineered Mesh • Lining: GORE-TEX Extended Comfort Footwear • Sole: Vibram® Flextron • GORE-TEX® • Vibram • Mammut Flextron Technology
