Nike Alphafly 1, size 26.5 cm. I haven't kept exact track of the distance, but I've probably run about 150 kilometers in these shoes, mainly during interval training. I've found shoes that suit me better than the Alphafly, so I've decided to sell these. They're used for exercise, so there are some scratches and dirt from use, but I think they're still perfectly usable. However, they are used, so please refrain from purchasing if you are overly concerned about minor imperfections. Feel free to ask any questions you may have.
