I bought this sneakers after reading that people used them for Zumba. In my case, they were very uncomfortable, painful actually. I have quite high arches and these offer no arch support. After, the Zumba class (painful 60 minutes of very little leg movement), when I changed into my regular (street) shoes I was much more comfortable and I was wearing 4 inches heels. In the name of vanity,  I have worn very uncomfortable shoes in my life, but I certainly will not wear them even once more.
Sizing was a bit weird too, I read that they run small, so I had to order 1.5 sizes bigger.
