On Running Cloudflow 4 (Men's) - Black/White
Light. Responsive. And seriously quick. Lead training or racing in a shoe that's fast for everyone.

Technology
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.

Materials
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.

Design
CloudTecin 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.

BEST FOR
Fast training, racing, 10K, half marathon, marathon, tempo running, long interval sessions
