I tested these out at work, walking on a concrete floor for 8 hours. They were very comfortable.

I love my Nikes, but these beat them hands down, and when I packed these in my suitcase and went back to my old shoes I felt it immediately. I ordered my normal size, 9, and they fit perfectly with plenty of room in the toes.See full review
