Size: Men's 25.5 These are discontinued, so I bought them and used them once for practice. I think I only used them for about 10km. After that, I injured my leg, and running in the Alphafly caused pain, so I'm now running in different shoes. I'm passing these on to someone who likes them! No bag included. I haven't worn them in a while, so I can't predict any deterioration. Returns due to deterioration are not possible. Nike Alphafly Marathon Carbon shoes
