I got these exclusively for Zumba based on other reviews. I go to Zumba twice a day, so my old running shoes were killing my knees. I should say that I used to have a pair of Ryka running shoes, which I wore a size 9.5, so of course i ordered these in 9.5, way too big! I returned them for a size 9, (though from another site that was cheaper with a coupon) which fit better, but it feels like there is a lot of room around my toes...i can move all my toes a lot, so maybe i should try tightening the velcro (yes that is velco..not that cute) but I don't think it will do much. I would really give these a 3 1/2 stars. They are way better than what I was wearing, but I think I could find better than this still. time will tell.
