I purchased this for my son away at college. It arrived quickly and he loved it. He said it was different then what he expected but really loved it. I have not seen it yet so I am reviewing this on what he said.

Fit as expected for Brooks. I love love these shoes. The change I love the most is that they got rid of the little bit of plastic covering that used to come up over the big toe side of the top. I attribute that bit of plastic/rubber to my bruised toes after a half marathon. The absence of that makes the toe box feel bigger. Not sure it's any wider, but it just feels so roomy and comfy. After a 10 miler in these I felt no discomfort in toes or anywhere else. Everything else, to me, feels the same as the Ghost 9s that I loved so much. Wonderful upgrade.
