These fit HUGE.  I normally get a 7 and I got a 6.5 and they are still really large.  The only other negative part about them is that they rub on the backs of my heels which is uncomfortable.  I am not sure if these are real or fakes.  They did not come in an adidas box or have the adidas tag on them.  They came in a plain brown box with no adidas tag.  Either way I still like them and think they are comfortable.  If they are a fake they are a good imitation.
