Developed for ultralong distances: The Ultra 100 trail running shoe for men is the ideal running partner upwards of 42,195 k (a marathon) and is impressive on any terrain. Most ultra shoes have one problem: They might be pretty comfy and well-cushioned, but they’re often too heavy, not precise enough, and a bit plodding when it comes to runability. To make it onto the podium, you however need a shoe that offers it all. To that end, this new Ultra 100 was developed together with the best ultra runners on DYNAFIT’s athlete team.
