On Frequently Asked Questions

Yes, the Cloudflow 5 runs true to size for most runners. On shoes are known for consistent sizing, so we recommend ordering your normal running shoe size. If you have a narrow foot, you may want to consider sizing down half a size, as On's fit tends to be slightly roomy in the midfoot and heel.

The Cloudflow 5 requires minimal break-in time thanks to its soft Helion™ HF hyper foam midsole and engineered CloudTec® cushioning. Most runners report comfort from the first wear, though we recommend wearing them for shorter runs initially to let the Speedboard® adapt to your stride.

The Cloudflow 5 is optimized for fast, tempo, and moderate-distance runs rather than ultra-marathons. Its propulsive Speedboard® and responsive Helion™ HF foam excel at maintaining speed and energy return over 5K to half-marathon distances, making it ideal for runners seeking a snappy, efficient ride.

The Cloudflow 5 features On's signature CloudTec® cushioning system paired with Helion™ HF hyper foam for maximum energy return without sacrificing ground feel. The cushioning is responsive and bouncy rather than plush, designed to propel you forward on faster runs while maintaining a low-to-moderate stack height.

The Cloudflow 5 uses high-quality engineered mesh uppers and a durable rubber outsole designed to withstand regular training. The Helion™ HF foam and glass fiber nylon-blend Speedboard® are built to maintain their performance characteristics for 300-500 miles of running before noticeable compression occurs.

While the Cloudflow 5 is primarily engineered as a running shoe, its sleek design and lightweight construction make it suitable for casual wear and gym sessions. However, it's optimized for running performance, so it may not provide the same all-day comfort as a lifestyle sneaker for extended casual use.

Clean the Cloudflow 5 by hand with mild soap and cool water using a soft brush on the mesh upper and outsole. Avoid machine washing and high heat drying, as this can damage the Helion™ HF foam and Speedboard®; instead, air dry at room temperature away from direct sunlight.

The Cloudflow 5 is more responsive and propulsive than the Nike Pegasus, with a firmer feel better suited for tempo runs, while the Pegasus offers more cushioning for daily training. Compared to the ASICS Gel-Excite, the Cloudflow 5 has superior energy return and a more premium build, though it's less cushioned for recovery runs.

The Cloudflow 5 is currently available in standard widths only. On does not offer a wide version of this model, so runners with wider feet may find the fit snug in the midfoot; consider trying On's other models like the Cloudmonster for a roomier fit.

The Cloudflow 5 comes in multiple colorways including classic options like white, black, and grey, as well as seasonal colors like blue, red, and neon accents. Availability varies by region and retailer, so we recommend checking the product page or contacting customer service for current color options in your size.
