Designed for very long distances, the Ultra 100 trail running shoe is the ideal partner for running distances greater than 42.195 km (marathon) and is impressive on any terrain.

The Ultra 100 was developed together with the best ultra runners from the DYNAFIT athlete team. The result is a shoe that perfectly bridges the gap between comfort, grip, and excellent energy return, bringing runners to the finish line with a better personal record.

Despite its maximum volume fit and high stack height of over 30 mm, it offers excellent grip and precision. The 6 mm drop aligns with the preferences of dedicated ultra runners.
