NIKE Alphafly 3, Eliud Kipchoge model, size 27.5cm. I bought these for marathon running, but I've decided to use shoes from a different brand, so I'm selling them. I've only tried them on once or twice and ran a few laps on a track, so the running distance is less than 1km. I threw away the original box, so I will ship them in a different box. Price negotiable.
