If you’re a runner who loves speed, efficiency, and that exhilarating feeling of flying down the road, the ON Cloudflow might just be your new best friend. Designed with racing and fast-paced training in mind, the Cloudflow combines ON’s signature CloudTec cushioning with a featherlight build to help you move faster, smoother, and more confidently.
But does it really deliver on all that promise? In this article, I’ll share a deep dive into everything you need to know about the ON Cloudflow — from its design and technology to who it’s best suited for and how it stacks up against other racing shoes.
First Look: Sleek, Modern, and Ready to Race
One glance at the ON Cloudflow and you can tell it’s made for speed. The shoe sports a streamlined silhouette and a breathable mesh upper that hugs your foot like a second skin without feeling tight.
It’s surprisingly light — one of the lightest shoes in ON’s lineup — making it easy to forget you’re even wearing them. Whether you’re hitting the track, racing a 5K, or pushing tempo runs, the Cloudflow promises minimal interference with your natural running form.
What Makes the Cloudflow Special? A Peek Under the Sole
CloudTec® Cushioning Pods
Like all ON running shoes, the Cloudflow features the unique CloudTec outsole — those hollow “cloud” pods designed to compress on landing and lock firm on toe-off. What makes the Cloudflow’s CloudTec special is how it’s tuned for a faster, more responsive feel, perfect for when you want to pick up the pace.
Speedboard™
Inside the midsole sits ON’s Speedboard — a springy plate that encourages your foot to roll forward efficiently. This tech gives the shoe that “bouncy” sensation many runners love, helping you conserve energy during longer races or intense intervals.
Helion™ Foam
The midsole uses ON’s Helion superfoam, which strikes a balance between softness and rebound. It cushions your landing while giving a snappy push-off — an ideal combo for speed work.
How Does It Feel to Run in the Cloudflow?
Lightweight and Responsive
From the first step, the Cloudflow feels light as air. It doesn’t weigh you down, and every stride feels quick and effortless. The shoe’s design lets you really feel the road beneath your feet without harsh impacts.
Snug but Comfortable Fit
The engineered mesh upper is breathable and flexible, conforming to your foot shape without squeezing. The heel lock is secure, so your foot stays put during sharp turns or sprints.
Just Enough Cushioning
While it’s not a maximalist shoe, the Cloudflow provides enough cushioning to protect your joints during fast runs on pavement. The CloudTec pods soften impact while keeping the shoe responsive, so you don’t lose any spring.
Who Should Consider the ON Cloudflow?
- Runners focused on speed: Whether racing 5Ks or doing tempo intervals, the Cloudflow’s lightweight design supports faster pacing.
- Runners who want a versatile shoe: It works well as both a racing flat and a daily trainer for faster days.
- Neutral foot runners: The shoe offers a natural ride without heavy stability features, ideal for runners with neutral pronation.
- Fans of innovative tech: If you like ON’s CloudTec and Speedboard but want something lighter and quicker, this is your shoe.
Pros and Cons of the ON Cloudflow

How Does the Cloudflow Compare to Other Racing Shoes?
Compared to Nike’s Vaporfly or Adidas Adizero, the Cloudflow stands out for its unique CloudTec cushioning, which offers a softer landing but with a different kind of responsiveness. It’s less aggressive than carbon-plated racing shoes but offers more cushion than typical racing flats.
Compared to ON’s own Cloudswift (which is more of a daily trainer), the Cloudflow is lighter, faster, and less cushioned — built specifically for speed rather than long, easy runs.
Real User Experiences
Many runners love the Cloudflow for its balance between speed and comfort. It’s praised for being breathable during hot weather and surprisingly versatile for different workouts.
Some users note it takes a few runs to get used to the unique CloudTec feel but say once you’re adapted, it’s a joy to run in.
Tips for Getting the Most From Your Cloudflow
- Use them for race days, speed workouts, and tempo runs.
- Pair with moisture-wicking socks to reduce blister risk.
- If you pronate heavily, consider a stability trainer for your longer runs.
- Replace after about 300-400 miles for optimal performance.
Final Thoughts: Is the ON Cloudflow Worth It?
If you want a shoe that’s light, responsive, and built for speed, the ON Cloudflow is definitely worth checking out. It’s not for everyone — especially if you need more support or want a maximal cushion — but for neutral runners who love pushing the pace, it’s a solid option.
The blend of innovative tech, style, and comfort makes it one of the best lightweight running shoes on the market today.
