I bought these shoes because I do Zumba at home, on carpet.  I used to just go barefoot, but felt like I needed more support, and help with my pivots.  I hopped on amazon and found these shoes (on sale!  woot!).  I am SO glad I bought these.  I was also looking at the actual zumba brand shoes, but I'm happy I went with these.  I prefer the black and they where half the cost!

These are really comfortable.  I ordered my normal shoe size and they were a tad snug upon arrival.  I just ended up wearing them with thin socks.  After a couple of uses they stretched out and are now VERY comfortable.  They fit like a glove.  I love being able to fully dance and do all of the moves on my carpet.  So glad I made this purchase.
