Nike Alphafly 2 NIKE Alphafly 2 [Product Number] DN3555-100 [Color] White/Clear Jade [Size] Men's 27.0cm [Description] I purchased these used on Mercari, but I am selling them because the size didn't fit. There is some dirt on the sole, but the grip is not very worn and there are no air leaks, so I think they can be used without any problems. Please consider purchasing, understanding that these are used items. === Just a few runs in the Nike Alphafly 2 will change your perception of your favorite racing shoes. Designed to provide rocket-like propulsion and help you cut down on your time, this shoe doesn't sacrifice the essential features needed for long runs. The thick, lightweight support system combines running comfort and speed. Experience the greatest energy return of any Nike racing shoe and leave your rivals in the dust as you aim for a personal best.
