Women's On CloudUltra 2

With softer Helion™ superfoam, this second-generation trail shoe delivers a smooth and comfortable ride on tough terrain. Plus, for an easier step-in experience, On has added a knitted sock upper made from 100% recycled polyester. 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 On's 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.
