This is the first colorway of the NIKE Alphafly, the original model worn by Suguru Osako, which became a hot topic and very popular. This model is now difficult to obtain. I've used them a few times for interval training and races, but I'm selling them because I won't be using them anymore. ・Size: 25.5cm ・Mileage: 171km The soles show some signs of wear, but there are no noticeable scratches or stains on the uppers. I will ship them with the original box and shoe bag (with some dirt). Please consider purchasing with the understanding that these are used items. No claims and no returns accepted. Thank you.
