These shoes are sexy and cute and have great beading, I got a 7 1/2 (my normal size) and my foot hangs off the back due to the positioning of the thong.  The base of the shoe doesn't offer a lot of cushion, so not for wearing for a day around town but definitely for a shindig.

So, order 1/2 size up and they should fit perfectly!  For the price, it's a very nice shoe.
