This shoe is not perfect, and I think is overpriced, but is the best Zumba shoe I have found so far.  I bought some of the dancing shoes with only a partial sole, and they had no support. These are light weight and have hard material on the bottom so you can move your feet and they lace up for support.  I do Zumba on a carpeted area, and these work better than standard tennis shoes, which are heavier and the bottoms don't slide as well on carpet.
