I use these shoes for Zumba. I needed something light with a smooth bottom. I ordered them elsewhere as they were cheaper.

At first I thought I wouldn't be able to wear these as they were too narrow in the instep (I also have this problem with Nike and usually wear Adidas).  My foot is not narrow, but a Wide shoe is too big.  I wore the shoes anyway, and they did develop some "give."

The only problem is that the sole is thin, and sometimes after doing heavy duty Zumba for an hour on a wood floor, my insteps can feel a little sore or burning.  But it doesn't last long.

I wear a size 6 in regular shoes, and a 6 1/2 in athletic shoes.  I ordered a 7 in this shoe and it fits. Also, I've had no problems with my ankles in this shoe, it seems supportive enough for me.
