I am a competative ballroom dancer who also does either Core Rhythms or Zumba 6 days a week.  I live in these sneakers--I am on my third pair but considering the workout they get they are really tough!  I have tried a few other brands but they are a little stiff, these are a little softer and more comfortable, they are great for exercise, rehersal,and practice. I just wish the judges would let me compete in them, my spins are a lot less wobbly that way.
