I bought these based on great reviews.  I bought them for Zumba.  They don't work for me.  There isn't enough padding for the ball of your foot.  I have pain in my toes during class.  They also are very slippery on wood floors.  They don't provide any traction during certain moves.  I've worn them to class three times, but they just aren't working for me.  I just ordered a pair of  Ryka moxie.  I hope those work out better.
