The very latest technologies elevate the Ducan Knit High GTX® Men from the cutting-edge of technical innovation directly to the mountains. The combination of Mammut’s proprietary Flextron, Georganic 3D and 3D Knit technologies make this agile hiking shoe fit for demanding alpine terrain. While Flextron works to prevent deflection of the foot with a spring-steel sole, therefore improving support, Georganic provides a fit tailored to the foot thanks to an anatomical last. 3D Knit also ensures elasticity and shape-adapting properties for enhanced comfort. The effect is supported by the high shaft that ensures greater safety in pathless terrain in the Ducan Knit High GTX® Men.
