This is the first model of the On Cloudmonster. I purchased it in 2024. I've used it for running, with about 80 kilometers of road running and only a few times on a treadmill. I believe it was the wide version. The size is a little too big for me, so I'm selling it. There is some minor dirt, but I think it's still a pair you can use for everyday wear! I used it with different insoles, so the original insoles are missing [I'm very sorry, I lost them]. It has been home-cleaned. Please take a good look at the photos before purchasing. I discarded the box, so I will carefully package it to prevent it from losing its shape during shipping. Thank you for looking!
