I got the black suede color, in a half size down from my normal shoe size (I got a 10 for my normally 10.5 to 11 US feet). I was originally turned on to these flats by an article by Stuff I Put on Myself by Natalie Dee.
They do fit like a ballerina slipper, hugging your feet and eventually stretching out to fit your own individual podiatric quirks. The black suede is nice and plain and looks exactly like a Cinderella slipper. They easily dress up or down. I'm going to buy another pair when these black ones bite the dust and maybe another pair in brown. They're fabulous!
