This is the Puma Fast-R Nitro Elite. Size is 28.5cm. Contrary to appearances, it offers good stability even with heel strikes, making it easy to run in and suitable for long distances. I like both the design and the running feel, but the fit is tight, and while it feels good, my wide feet cause my little toes to hurt on longer runs, so I'm selling them. I mainly used these as my race shoes for ekiden and road races. They have been used for approximately 30km and are in good condition, I think. Shipping will be in simple packaging, wrapped in bubble wrap. Thank you.
