Nike Vaporfly Next% 3 These are carbon-plated, thick-soled racing shoes. I used them in a race last season and have used them several times in training since then, so they show some signs of wear. However, the outsole is still in good condition, so I think they're perfectly usable for training. The uppers have no noticeable dirt or tears. As you'll likely be increasing your training for marathon races, how about using these for practice at race pace, simulating the actual race? I'm selling these after having cleaned them thoroughly by hand at home, so you can use them comfortably upon arrival. Thank you for your consideration. #Marathon #Running #TrackAndField #Alphafly #Adizero #Metaspeed
