So I got these for Zumba, after reading some reviews and recommendations.  I learned that regular sneakers can cause injuries, but these were supposed to be great because they're more like a dance shoe.  And they are more like a dance shoe, and I love how they fit and feel.  The "TWIST" is a slick part on the bottom of the shoe that they really should show you in the product images.  Because man oh man is it ever slick.  I wore them to Zumba once and probably will never wear them again...my natural inclination is to use the balls of my feet in class, which totally messes me up with these super slippery shoes.  I love the split sole and I love how they look, but not very safe for Zumba in my opinion.
