Strange, what type of pain did you have? I have both the regular and flyknit 9.5s and I found the flyknits both more comfortable and more durable! The toe area is tearing on my 9.5s but the flyknits are both fine, with the same amount of mileage on them. Only thing with the flyknits is I'd like to have bought them 0.5 size smaller but nothing that can't be fixed with a thicker/extra sock.God I hope they are better than the Flyknit versions of the 9.5. I really loved my regular Vapor 9.5's, bought a pair of the flyknit versions and HATED them. Some of the worse shoes I've ever worn on the court. Finally just wore them as regular walk around shoes as I was in massive pain when I played w/ them. They were a terrible transition from the regular version.
