Anyone who has ever run an ultra knows how important it is to be able to brave the elements. Depending on terrain and route, it is not uncommon to encounter all four seasons along the way. In preparation for all eventualities, the new FORTUX GTX is equipped with a waterproof, breathable GORE-TEX membrane which enduringly protects running feet from getting wet.

With the Lowa Trac Ultra non-slip rubber outsole you get the necessary stability for fast-paced long-distance runs. The lugs are bi-directional, allowing for both quick acceleration and responsive braking.
