Size and fit

The Ducan High GTX is a high-top backpacking boot built for men and women. It uses an Asymmetric lacing system to help wearers get a customized lockdown. This component works with a one-sided tongue and an anatomical last with a mono tongue to achieve a secure and comfortable fit. The tongue also minimizes pressure on top of the ankle and foot. Moreover, the footgear’s cuff features Memory Foam for a plush fit around the ankles.


This Mammut boot for backpacking adventures comes with a Vibram Flextron outsole. It is made of a sturdy Vibram Trek rubber compound for resistance to wear and abrasive elements. The outsole’s profile uses a pattern of trapezoid-shaped lugs to render grip on challenging terrain. It also incorporates a heel brake into its design for extra control when tackling downhill conditions.


Mammut Ducan High GTX users are granted sufficient cushioning and shock absorbency, thanks to its EVA midsole. It features the brand’s proprietary Georganic 3D technology, which uses a geometric-dynamic design, to support the natural movement of the foot and prevent pronation.

This backpacking boot from Mammut has a spring-steel sole, called Flextron, embedded within its midsole. It functions by giving vertical support while preventing deflection of the foot. Moreover, the footgear’s default footbed offers arch support and extra comfort underfoot.


The Mammut Ducan High GTX is equipped with an upper made of engineered mesh. This material reduces the overall weight of the boot, making it lightweight. A Gore-Tex Extended Comfort membrane lines the upper to prevent water from entering while allowing excess moisture to escape. It also has thermoplastic polyurethane (TPU) overlays for structure and durability.

The Ducan High GTX’s rearfoot region uses a molded counter for heel support. A rand wraps around the toe box to protect from accidental knocks. The boot’s lacing system employs a series of fabric loops and metal hooks to help the wearer manage its fit. Its Memory Foam-equipped ankle cuff and mono tongue prevent debris from entering the footgear. A pull tab is positioned at the cuff for easy on and off.
