The DYNAFIT Ultra 100 W Trail Running shoe offers maximum cushioning. It was developed for all women athletes striving to conquer ultra long distances. The maximum volume of the ULTRA 100 Trail Running Shoe guarantees a comfortable fit even after hours of running on challenging trails. The cushioning needed for long runs was a key focus during the development of the ULTRA 100 midsole. Combined with a POMOCA outsole, ultrarunners get excellent cushioning and superb grip on all surfaces and conditions. With the Invisible Lacing system, a stretch lace cover adds increased protection and keeps dirt and pebbles from getting into shoes. Another feature of the ULTRA 100 is the DYNAFIT Heel Preloader Technology – a design element that improves heel fit. With all of this, the ULTRA 100 is the perfect overall solution for your next, long trail adventure.
