What runners say

Amazing shoe

, Houston, I run over 40km per week, I run primarily to start and have fun

These honestly may be the most comfortable shoe I have ever put on and owned in my life. They are a perfect "quick" run shoe, as in my opinion 6 miles or less. After 6 miles or so my feet began to hurt bad, real bad. The first 6 miles, like riding on a cloud. I use these as my speed trainer and my other brand shoe as my longer run shoe. With all that said, I have no negative review on the shoe whatsoever as I believe they weren't necessarily intended for a real long run. If you are looking for a trainer that is comfortable, extremely light, and make you go faster than you thought possible; look nowhere else than the Cloud X. This is my first experience with the On-Cloud brand and I love them. I will be buying other platforms of the On brand as in everyday wear, that's how impressed I am.

Tennis Anyone...?!

, New Orleans, La, I run 0 - 20km per week, I run primarily to train to race and compete

I picked up a pair of these at our local running store where I have shopped with my Cross Country running daughter. I was just going to use them for cross training when I mentioned to salesperson that I play tennis. She said these may be good for tennis. I played in them the next day and haven't turned back. They are great for tennis. I used to have sore feet after playing in, you name it, Nike, New Balance and Babolat tennis-specific shoes. Not with my ON's! The only problem is that they leave a mark on the clay courts where the wedge/valley runs the length of the shoe sole. Maybe ON can design a tennis specific shoe. I think they would sell.

, Pennsylvania , I run 20 - 40km per week, I run primarily to move and explore

Love them...I have had my knees replaced twice also my hips .They are so light and comfortable .Wish I would of found them before.By far the best sneaker ever purchased ..I tried every brand out there believe me ....Still active and wanted to find something comfortable and I have..Thanks.

I love with running on the clouds

, Knaresborough , I run 0 - 20km per week, I run primarily to start and have fun

I have bought my first Clouds X last year and can’t praise them enough. 
In my opinion best trainers by a mile and could compete to the top ones on the market. Since than I am the owner of three different pairs and also got one pair for my partner. We love ON!!!!!!!!!    

No more knee or lower back pain

, Athens, Ga, I run 0 - 20km per week, I run primarily to move and explore

Always wanted to run outside of being on a soccer field but my knees and lower back would always hurt when I was running on the street. I didn't want to spend 300 dollars on a good pair of running shoes so I just dealt with it until I came across these in a store. First time I ran in them my knees or back didn't hurt and I could really feel it in my quads from where my improper mechanics hadn't ever stressed my inner quads. Love these shoes and are very comfortable to wear as every day walking around shoes.   


, USA, I run 0 - 20km per week, I run primarily to move and explore

I have never fallen so quickly in love with a pair of running shoes. I thought that I would inevitably have shin and knee problems and I would never find the right shoe, but I feel no more pain! They're supportive while still adding comfort and cushion.
