These are one of my favorite running shoe models and this is my  second pair! The first was given to me by an employee at my local running store who was given them by a Nike rep. I have to be honest that I never would have lookednat Nikes otherwise. I have a neuroma in my foot that requires a wide forefoot in a shoe and/or flexible fabric. The Flyknit on these is perfect for what I need. I wore these straight out of the box for the Boston Marathon after realizing my original pair were past their prime after running 2 marathons in them. Conditions were rough in Boston this year, but my shoes caused me zero problems! Great cushioning and support.
