NIKE Alphafly - 25.5cm Used for approximately 150km. * One puncture on the outer side of the left shoe. They're still in good condition and usable for training, but I'm selling them because one pod on the right shoe has punctured. If you have the first generation Alphafly and it has a puncture on the outer side of the left shoe, these might be a good match. Other than the punctures, the condition is good. What do you think? Please consider them.
