A cushioned, all-terrain trail shoe for long distances and ultrarunning, with soft Helion superfoam and Missiongrip . With softer Helion superfoam, this second-generation trail shoe delivers a smooth and comfortable ride on tough terrain. It also does a neat job of keeping dirt out while allowing air in. The new Missiongrip outsole and updated stud layout provide 50% more ground contact for enhanced traction on tricky terrain. Plus, with a more precise fit and durable upper, you'll feel sure-footed as you fly across roots, rocks and whatever else the trail has in store. The TPU Speedboard loads with energy every time your feet land, while our signature CloudTec cushioning protects against impact. Together, this powerful pair propels you forward – step after step, mile after mile. Because when you're running an ultra, every moment matters.
