NIKE Air Zoom Alphafly Next% Size: 25.5cm Color: Turquoise This is the popular first-generation Alphafly. I've run about 350km in these, and I'm selling them because I've changed racing shoes. They still have good responsiveness and propulsion, but there is a small scratch on the material of the outer pod on the right foot, but it is not punctured. This shoe has many core fans. If anyone is interested in wearing them, please consider purchasing them with the understanding that they are used. Returns are not accepted, so please understand this beforehand.
