After returning the original size 91/2 and ordering a 10 1/2 they fit fine and are working out. I would say your shipping and handling for returned shoes is excessive and you should make your customers aware.
Love these shoes. I read the previous reviews and did order up a whole size, they are still a bit snug I usually wear a 6 ordered a 7 and will probably order a 7.5 the next go around. The bottoms are great they glide you across the dance floor no problem at all.
The dance sneakers are comfortable. I wish they made the same style in black. They fit true to regular sneaker size. One thing that was a little strange, but I guess it's how these shoes sit in the box during shipping. When I got them and opened the box, even though the shoes were wrapped correctly, it looked like they were all apart - the padding inside the shoe was falling out and it looked like the shoe itself was smushed. But once I adjusted everything correctly and put it on my foot, it was fine.
So far I have only worn them twice but I am happy with them. They are comfortable and light. You do need to order one size up, however. I did not and had to send them back for exchange.
Runs Very Small, pick at least one size up, maybe two
