The DYNAFIT Ultra 100 W Trail Running shoe offers maximum cushioning. It was developed for all athletes striving to conquer ultra long distances. The maximum shoe volume guarantees a comfortable fit even after hours of running on challenging trails. Needed cushioning was a key focus during the development of the Ultra 100 midsole. Combined with a POMOCA outsole, runners get excellent cushioning and superb grip on all surfaces and conditions. With the Invisible Lacing system, a stretch lace cover adds increased protection against dirt and pebbles getting into shoes on the trail.
