Synthetic leather lies atop a stretch mesh sock so your foot gets some fresh air. The off-center boa lacing system eliminates mid-trail lace fumbling. Beneath your sole lies a supple, 4mm PU foam insole.
The ShapeShifter last has a foot-like shape for an anatomically-oriented fit to give your maximally cushioned running a natural feel. The pliant nature of the injection-molded EVA midsole and Morpheus sole helps the Ultra adapt to the nuances of the trail while buffering against impact forces and sharp trail trash. You'll find multi-directional lugs all along the lateral edge of the sole for traction over different types of terrain. The medial lugs are designed to give your foot strike stability
