W On Cloudflow 4

Light. Responsive. And seriously quick. Lead training or racing in a shoe that's fast for everyone.

Fast is now for everyone

You wanted speed. So we added a spoon-shaped nylon blend Speedboard® that's stiff, strong and lighter than before. Added to a powerful forward roll to catapult you to new personal bests. Put simply, you'll feel it.

Looks light. Feels light.

The ultra-light woven upper takes a cue from our fastest shoe yet – the Cloudboom Echo. The result? Breathability and performance that makes picking up the pace easier than ever.

Softness like never before

CloudTec® in Helion™ dual-density superfoam now runs throughout the shoe. Impact is swallowed, meaning every stride is softer underfoot. What's more, it gives back an ultra-responsive running sensation. And that's crucial to going faster, and staying faster, than you have done before.
