The waterproof Ultra 100 GTX Trail Running Shoe for women is your perfect partner for long runs in wet conditions. 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 need a shoe that offers it all. This new Ultra GTX 100 was developed in partnership with the best ultrarunners on the DYNAFIT Athlete team
