I mentioned a few days ago that I was considering Nike Free 3.0 for my next running shoe. Well, I bought the shoes. What sold me on this shoe is how well they fit on my feet. The uppers conform to my foot like a sock. The entire upper is a continuous flexible material. The shoelace just provides a snugger fit. The sole is extremely flexible. It is cut into several deep grooves the length of the shoe and across it. Oh, and they aren't very heavy at 7.8 oz. Running in these shoes is like running...ah, it's like a barefoot shoe. Take a look.
