Dynafit Ultra 100: Developed for Ultra-Long Distances
Bee Trail.nl Introducing the Dynafit Ultra 100 trail running shoe for women, the perfect partner for distances over 42.195 km (a marathon) and impressive on any terrain. Many ultra shoes have one problem: they're often comfortable and well-cushioned, but also too heavy, lacking precision, and less responsive to the touch. To reach the podium, you need a shoe that offers it all. That's why this new Ultra 100 was developed in collaboration with the best ultrarunners from the DYNAFIT athlete team.
Features
- Maximum Comfort and Precision: Despite the maximum volume fit and a high stack height of more than 30 mm, this shoe offers excellent grip and precision from the first to the last step.
- Ideal for ultrarunners: The 6mm drop is tailored to the preferences of dedicated ultra runners.
- Superior Grip: The Vibram® Megagrip sole with 4 mm deep studs provides improved traction and perfect grip on any surface.
- Lightweight and Responsive: The new midsole is 20% lighter than traditional EVA midsoles and provides an energy return of more than 10%.
- Dynamic Role: The rocker shape of the sole ensures a smooth and dynamic transition, even on tired legs.
- Stable and Comfortable: The Heel Preloader and anatomically correct heel construction provide a secure fit and reduce stress on the Achilles tendon.
- Individual Fit: Traditional lacing with a seamless tongue construction prevents pressure points, and the laces can be safely stored in the stretch lace cover.
Damping
The Dynafit Ultra 100 offers excellent cushioning thanks to the innovative SPEED+ midsole. This midsole is not only 20% lighter than traditional EVA midsoles but also provides over 10% energy return. This creates a springy and responsive feel while running, giving you long-lasting comfort and reduced fatigue, even over ultra-long distances. The cushioning effectively absorbs shock and protects your feet from rough terrain, resulting in a smooth and comfortable running experience.
Fit
The Dynafit Ultra 100 has a maximum volume fit, meaning the shoe is roomy enough to keep your feet comfortable over long distances. This prevents pinching and blisters, and provides ample room for the swelling that often occurs on long runs. The anatomically correct heel construction and quick-closure system ensure a precise and personalized fit, keeping your foot secure and stable, even on technical terrain.
