Thank you for viewing. This is the NIKE running shoe "Alphafly NEXT%". The size is 27.0cm. This is a brand new, unused item. Purchased from the NIKE online store. The color is listed as Hyper Turquoise, but it's a Tiffany blue-like color. These shoes combine the original Air and carbon fiber, and you'll likely feel the most responsiveness with the first generation. I've decided to step away from track and field, so I hope someone can use these. How about a pair for the upcoming marathon season? I'm also listing other running shoes, so please take a look if you'd like.
