NIKE Air Zoom Alphafly NEXT% 2 (27.5cm). Reportedly, athletes at the World Athletics Championships have worn these in the past. The included shoe bag is also used, but it's included. These have been worn multiple times, so there are some stains and scuffs. I've mostly only used them to go to and from home and the gym, so I probably haven't run more than 15km in them. The soles show signs of wear, but otherwise, the condition is good. Thank you for your consideration. ※Important: Returns and exchanges are not accepted.
