The Sapuen High Gore-Tex® is the right choice on all kinds of terrain. Mammut Flextron Technology™ supports the natural rolling movement of the foot and thus more efficient use of energy when hiking and mountaineering, while Mammut Georganic 3D Technology® guarantees maximum comfort. All components in contact with the foot are anatomically shaped with great precision while the classic tongue construction offers easy entry. Optimized for hiking: a Vibram® rubber blend for secure grip on outdoor surfaces and a sole design that supports self-cleaning. The waterproof Gore-Tex® membrane guarantees dry feet.
