I loved these the moment I received them!  Both the style and the color (lollipop) are so cute!  I agonized a bit over what size to order since I wear a 6.5M and they don't come in half sizes.  The reviews gave me mixed feelings so I ordered both a 6 and a 7 to be sure.  I was a little concerned when I received them.  They turned out to both be wide width even though Amazon lists them as medium (M) width and the Zumba website lists them without any width.  I wouldn't have bothered with the 7s if I knew they were wide.  If I'm going to wear a wide, it'll usually be a 6W.  After I found out they only come in wide, I decided to keep the 6s.  They're quite comfortable although there is a good amount of room in the toe.  I've used them for Zumba twice now and I like the way they glide on the floor and I can pivot with ease.  They're also lightweight and cool.  I feel much more like I'm dancing than I do in my running shoes that stick to the floor much more.  I do wish they fit a tad bit more snugly on my feet, but I'll probably try some insoles to take up some room, other than that they are a good fit and they feel good to dance in.  ...Oh, and did I mention they're too cute?!  :)
