Sporty and agile: a winter edition of Mammut's Ducan. The latest technologies make the Ducan Pro High GTX Men a hiking shoe for winter conditions in the mountains. The shoe’s warm lining ensures very good insulation in cold temperatures. The core feature is the Mammut Flextron technology, which integrates a spring-steel sole as a midsole in the shoe. This prevents deflection of the foot and provides improved vertical support for more efficient use of energy on hikes and climbs. Mammut Georganic 3D Technology ensures a natural foot movement when wearing the Ducan Pro High GTX Men. A geometric-dynamic design is combined with a cut that is organically tailored to the foot. A great fit is ensured by an anatomical last, asymmetric lacing and a mono-tongue for one-sided entry. The focal point is the anatomical last which, together with the asymmetric lacing and mono-tongue for one-sided entry, provides a really good fit. With a Vibram® sole designed specially for winter conditions, the Ducan High GTX Men provides outstanding grip on the icy surfaces that may await you out in nature and in the mountains.
