So far they're great! I use these for every Zumba class.  Before I gave these a try, I wore shoes with a lot of tread which gave me knee pain. That's not the case anymore thanks to these shoes. The shoes get a little slippery when it comes to moving on a gym floor but I don't feel like I'm uncoordinated enough to fall.  It's just minor sliding sometimes.

There aren't a lot of opportunities to do toe points in Zumba, but I do like the freedom it gives the foot when it comes to flexing and bending.  I would recommend these shoes, especially if you're a size 10 like me and don't want to buy a shoe size 4 sizes up, which would only make one feel like a Sasquatch!
