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. The result: A shoe that perfectly bridges the gap between comfort, traction and excellent energy return to carry you to the finish line with a personal best. Despite its maximum-volume fit and high stack height of more than 30 mm, it is an impressively spritzy buddy with excellent grip and precision from the first to the last step. The drop of 6 mm speaks to the preferences of committed ultra runners. For the sole, developers utilized the Vibram® Megagrip blend, which sets the standard in competitive sports for highest performance. The new Vibram traction lugs are employed for the first time in the Ultra 100. This innovative lug concept with 4 mm deep lugs guarantees improved traction and perfect grip so runners can move over any surface securely and with precision. The midsole features comfortable cushioning for a springy feel, but also remains responsive and light. The new material weighs 20% less than a traditional EVA midsole, but at same time has an energy return of more than 10%. Together with the Heel Preloader, the anatomically correct heel construction ensures a secure, stay-put hold and enables top control and stability. At the same time, stress on the Achilles tendon is lowered. In addition, the sole’s rocker shape lends a dynamic, fluid roll-through that promises running flow all the way to the last step on heavy legs. The Ultra 100 comes with traditional lacing that can be ideally individualized to your personal needs. A seamless tongue construction hinders pressure points, and you can stash the laces securely in the stretch lace cover.
