Discover the New On Cloudflow 4: Lightweight Speed Meets Enhanced Cushioning

The Cloudflow from On returns in 2023 with a refreshed design that maintains the familiar ride of previous generations, now elevated with better performance and added cushioning.

The new Cloudflow 4 is one of the lightest On running shoes yet, weighing just 200 grams in women's sizes and 235 grams in men's.

What’s New in the Cloudflow 4?

This fourth edition features a brand-new upper crafted from 100% recycled polyester. Its design draws inspiration from the elite-level, carbon-infused Cloudboom Echo 3—resulting in a speedy, breathable shoe ideal for hot-weather runs and training sessions.

Perfect for fast-paced workouts and 5K to half marathon races, the Cloudflow 4 is especially well-suited for lighter-footed runners seeking agility and comfort.

Enhanced Tech for Smoother Strides

The Cloudflow 4 features a stiffer, more responsive Speedboard® and a dual-density Helion™ superfoam midsole powered by CloudTec® technology. Compared to previous versions, it incorporates more outsole rubber for improved shock absorption—offering greater protection for your knees and feet.

"You will feel it"—that’s the promise from On’s Zurich-based lab designers. Improved grip rubber pads also deliver superior traction on wet roads.

The result? A shoe with higher energy return, added stability, and softer impacts—making it the perfect balance of speed and comfort. If you're chasing performance in an On running shoe, the Cloudflow 4 is a top contender.
