Wow, this is one BRIGHT shoe! I normally wear a size 7 and decided to try this in a size 8. I'm glad I did because they fit perfectly. So these shoes must run a little small. They are really comfortable with the top having material that bends easily. I don't like the big silver Zumba on the back of the shoe. I guess if you Zumba you might not be bothered by it. I will use these on the treadmill at the gym and when I exercise at home. They easily glide over carpet. I would prefer a more subdued color, but it's still a good shoe. Recommended.
