I will begin why I gave a 4. First pair I ordered were size 6, my normal size, but in these were way to tight. I returned and ordered one whole size bigger 7 and they fit perfectly, so if you are a fitted 6, may want to even go 7 1/2. Perfect shoe for doing Zumba, light, wearable for all the moves, I think they are a great investment for my Zumba workout.
