Mizuno Neo Zen 25.5 Black x Black Used for approximately 20km. I bought these new with the intention of using them for my commute run, but the size didn't quite fit, so I'm selling them. I think there's almost no damage or dirt. Please check the photos for details before purchasing. Regarding the size, I felt they were a little small. I could still run in them, but they were a very snug fit. I wear Wave Rider 27 in 25.5, but I think a half size larger would be better for the Neo Zen. This is just my personal opinion, so please take it as a reference. Thank you.
