Back with even more performance, On Running 's CLOUDULTRA 2 W is a second-generation women's trail shoe sized for ultra-running off-road.

Easy to slip on thanks to its sock-like upper made of recycled polyester mesh, this model is very comfortable to wear, as it wraps the foot nicely and is very lightweight and breathable. It owes its running performance on difficult terrain to its ultra-soft Helion super-foam, combined with a new Missiongrip outsole with redesigned lugs offering 50% more ground impact. What's more, this shoe combines CloudTec technology in the Zero-Gravity foam for softer cushioning, with improved Speedboard that transforms energy into motion to propel you forward, crowd after crowd.

Last but not least, it adds an elastic strap for safe storage of laces.
