This is a great shoe for Zumba. As other reviewers have said, this shoe does not fit like a tennis shoe. It is very snug around your foot and has pretty good cushion in the ball of the foot and heel. It does not have any arch support, so if you need arch support look for something else. If you like me and doen't really feel like you need the exta support, it's great! Also, it's doesn't have much stability in the sides. This is a DANCE SHOE, so I really wouldn't recommend it for anything else. It does run a bit large. I normally wear a 7.5 and the Medium (7/8) seemed fine at first, but once I started working out in it, it seem a little too large. I was wearing them without sock, so I will try them with sock next time. I am going to go ahead and order another pair in Small to wear without socks, as well.
