On Cloudflow Review

On Cloudflow Review.jpg

The On Cloudflow was my first introduction to On Running. I bought this shoe with the intention of using it for tempo runs, long runs and my race day for half marathons and up. I don’t have a specific brand that I love and go to all the time. Some of my previous favorite running shoes have come from Asics, New Balance, Mizuno and Saucony. But of course, all those companies had to discontinue or radically change all of my favorite models. I had been hearing great things about On Running from friends and runners and when it came time for new shoes, I thought I would try them out. I’ve put 100’s of miles on the Cloudflows, so let’s dive into my review!

Support: Neutral

Most of the shoes in On Running’s lineup are neutral and the Cloudflow certainly is.

Fit: Narrow to normal width feet

Weight: Women’s 6.7oz / Men’s 7.76

Drop: 6mm

Activity: Training/Racing

When I put on these shoes, I’m usually running fast in them! I wear them for my tempo runs, faster long runs and I’ve even done some intervals on the track with them. I think for most, this is going to be a very versatile race show and can range from races as short as 5k all the way up to a marathon for people who want a lightweight responsive shoe.

Terrain: Road only (avoid trails!)

All of On’s road running shoes are famous for picking up rocks in the Cloudpods on the bottom of the shoe. I have a short little trail I often take by my house and I always pick up pine cones! These shoes are absolutely not recommended for trails, but if you will be running pavement only, you won’t have an issue. Also, avoid running in this shoe on wet pavement. I hope this is fixed in future versions of the Cloudflow, but I find it incredibly slippery on wet roads. I would definitely not wear this shoe on race day if the roads were wet.

Cushioning: On’s website says Moderate cushioning but I find it quite plush.

This is easily the most cushioned feeling fast shoe I’ve ever worn. I’ve had Asics Nimbus and other more cushioned shoes in the past, but the Cloudflow was meant to go fast and usually fast shoes don’t feel this good. I was shocked when I looked up how light the Cloudflow is. I couldn’t believe they made such a well cushioned shoe and kept the weight under 8oz (for my men’s size 8.5).


  1. Lightweight, responsive and fast shoe.

  2. Great for racing all distances.

  3. Built in sock liner so you can go sans socks.

  4. Comes in multiple color options.


  1. Not an option for trail running. Rocks will absolutely get stuck in the bottom of the cloudpods.

  2. Very slippery on wet pavement. I wouldn't trust this shoe on race day if the roads are wet.

  3. Not a suitable option for those with wide feet.

On Cloudflow Review: 9/10

Overall, this might be my favorite shoe of all time! A shoe that really does it all (with the exceptions of trail running and wet road running, haha). A comfortable, well cushioned shoe that’s a joy to train in, but still lightweight and responsive enough to throw down fast times amongst races of any distance.
