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

The Cloudflow 4 IKON is reimagined in a sleek new design that looks as good as fast feels. Drawn from contemporary sporty styling, the shoe features TPU layered lines and a shade-on-shade coloring method for street-ready wear plus race performance. Presented in special-edition packaging.

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.
