From the Nike website: Fine-tuned for marathon speed, the Alphafly 3 helps push you beyond what you thought possible. Three innovative technologies power your run: A double dose of Air Zoom units helps launch you into your next step; a full-length carbon fiber plate helps propel you forward with ease; and a heel-to-toe ZoomX foam midsole helps keep you fresh from start to 26.2. Time to leave your old personal records in the dust. From me, the guy who wore them: I wore these exactly one time, and for 26.2 miles (Boston Marathon.) I wanted so bad to like these, but I went Adidas Adios Pro 3 awhile back and think I need to stay in that lane. These are rad, just not the fit for me. They are in near mint condition, aside from the 26.2 currently on them, and ready for your next race. These seem to be sold out everywhere. Color: Volt/Dusty Cactus/Total Orange/Concord I do not have the original box, sadly, but they do come with the shoe bag.
