I wore these in one Zumba class and they were very uncomfortable and ended up hurting my feet. I do feel that you should just get 1/2 size larger than your normal street shoe, though. I wear a size 9 and got a 10 due to the reviews. Though these fit, I think they should fit a little more snug; for Zumba, anyway. You don't want your foot moving around in the shoe. They seemed a little clunky to me too. Kind of like I was wearing a man's shoe. I returned them and got a pair of Capezio Women's Web Dansneaker; and I love them!!
