Introducing the Cloudflow 4: Lightweight Innovation

Weighing just 200 grams for women and 235 grams for men, with a 9mm heel-to-toe offset, the Cloudflow 4 is one of On's lightest shoes yet.

What sets this 4th edition apart? The brand-new upper, crafted from 100% recycled polyester, takes cues from the fast, carbon-infused Cloudboom Echo 3. This results in a speedy, lightweight road running sneaker that offers enhanced breathability, perfect for scorching summer workouts and training sessions.

Ideal for fast training and races from 5K to half marathons, especially for lighter runners, the Cloudflow 4 features a fast Speedboard® with improved stiffness and strength, alongside Cloudtec® in Helion™ dual-density superfoam throughout the shoe. This new design absorbs more shock, providing enhanced impact absorption and protection for your knees and feet.

The upgraded grip rubber pads in the outsole offer better traction on wet surfaces, while the advanced sole technology delivers next-level energy return, strength, efficiency, and gentler impacts for your legs. The result is a shoe that enables a more cushioned stride, perfect for those seeking speed in their On running shoe.

Fast is now accessible to everyone with the Cloudflow 4. Experience the power of a spoon-shaped nylon blend Speedboard® for a powerful forward roll, an ultra-light woven upper inspired by the Cloudboom Echo for breathability and performance, and Cloudtec® in Helion™ dual-density superfoam for softer, more responsive strides. It's time to go faster and stay faster with the Cloudflow 4.
