Nike Air Zoom Alphafly Next % (Nike Alphafly running and road racing shoes) Size: 24.5cm Style #: CI9925-400 Color: Black / Lime Green This is the first generation of the Nike Alphafly series. I ran three half marathons in these and also used them for pre-race training (approx. 100km). They still seem like they can be worn for a long time. Condition: Used. The uppers are in good condition. There is some wear on the outsole. Original box not included.
