I was looking for a lightweight and supportive shoe that allowed me to slide fairly easily while taking Zumba, but didn't want to spend a fortune.  I have arthritis in my knees and hips and needed a shoe that didn't inhibit the turns and slides of Zumbas, and I also needed a shoe that worked with my high arches. I had bought and tried a couple of different shoes trying to find one that didn't leave the ball of my foot in pain or cause numbness like other shoes did.  I also didn't want to spend even more money and not have these work out.  I researched and thought I'd try these.  So, I bought the clearance color and love these!  I will definitely return to Realflex shoes for Zumba in the future.  I don't buy from the other big brand because they use a dog abuser sports figure in their ads.
