I have had trouble finding sneakers that don't hurt the balls of my feet. When I started ZUMBA, I found the jumping/ high impact moves made this problem even worse. Plus, sneakers would not slide well for turns, etc. I tried several different pairs of sneakers wiht no success, then did a search in amazon for "zumba shoes" and  "dance shoes." These got good reviews from others. so I decided to try a pair. There was free return shipping so I had nothing to lose! According to the reviews, these shoes run a bit small, so I ordered 1/2 size bigger than my regular size. They were perfect! There was no "Break in" time required...from the first time I wore these, they were comfortable and I was able to do an entire 60 minute session without pain! And the soles slide easily, but provide enough traction to do lunges. I highly recommend these!
