What is the Ducan III High LTH GTX?
The Mammut Ducan III High LTH GTX are traditional hiking boots built for comfort, protection and durability over medium to long distances and multi-day hikes. Designed to tackle technical terrain, they blend Mammut’s heritage craftsmanship with modern innovation, delivering stability, waterproof protection, and plush all-day comfort on every step of the journey.
The Ducan III High LTH GTX are perfect for hikers and trekkers who value traditional leather durability but want modern hiking comfort. Ideal for medium to long-distance routes, multi-day treks, and demanding hill walks in variable weather, they offer dependable protection and performance, season after season.
What are they made of?
Outer: The Ducan III High LTH GTX feature a premium Heinen Terracare Nubuck Leather upper which is sustainably produced in Germany and renowned for its exceptional durability, natural comfort and adaptability. This is reinforced with a TPU protective rand, offering outstanding resistance against abrasion and trail debris without compromising flexibility.
Lining: A GORE-TEX® Prism membrane delivers full waterproof protection and breathability, ensuring your feet stay warm and dry even in wet conditions. This weather-ready lining keeps moisture out while efficiently wicking away internal sweat, maintaining comfort across changing terrain and climates.
Midsole: The dual-density High Rebound C-EVA midsole provides long-lasting cushioning and energy return, reducing fatigue during long days on the move. Integrated with Flextron® PRO technology, a polymer plate stabilises the foot and prevents energy loss, improving hiking efficiency and posture on uneven ground.
Outsole: Underfoot, the Vibram® XS Trek Outsole with Traction Lug® technology ensures unbeatable grip and control on wet rock, mud, and loose gravel. The lug design enhances braking and propulsion, helping you stay confident on steep ascents and descents.
What are their features?
These boots are built for real-world mountain performance - stable, supportive, and ready for technical ground. Despite their sturdy build, they weigh in at around 550g per shoe (size 8), offering an excellent balance between protection and agility.
The Mammut Hiking Comfort Fit gives your toes freedom to move while maintaining a snug heel lock for secure foot placement on rugged terrain. The anatomical design supports natural movement and reduces pressure points, especially during long hikes.
This combination of leather luxury, innovative midsole design, and superior grip makes the Ducan III High LTH GTX a versatile choice for hikers seeking reliability over multiple days and varied conditions.
