The Nike Zoom Fly is a running shoe equipped with a lightweight and responsive ZoomX sole. - Brand: Nike - Model Name: Zoom Fly - Color: Red/Green - Sole: ZoomX - Outsole Material: Rubber I'm listing these because it would be a waste to throw away the shoes my younger brother used. The outer edges are slightly scuffed due to his running form, but it's not very noticeable. I think they are perfectly fine as training shoes, rather than for races. I recommend them for those who are just starting to run, for students in sports clubs, or for anyone who wants to try out their first carbon plate shoes. Thank you for looking.
