I ordered these knowing that a few people had said they ran a bit large, but I found that they fit rather well. I usually wear an 9-9 1/2 women's sneaker, but ordered a 9 just in case they were somewhat larger.  I can fit two fingers in the back of the heel, but just barely, and my foot & toes have room to spread out, and aren't cramped like in some shoes. Aren't as cushy as some sneakers, but I think I'm going to add in a pair of Dr. Scholl's inserts anyway, so that should fix it. All in all, these are a GREAT, great-LOOKING pair of shoes. No problems with the order, either. They came REALLY fast!
