I was very excited to find a more sophisticated ballet flat.  Most others on the market feature a giant bow, jewel or some other childish accessory, or are so rounded at the toe that your feet will look stubby and child-like.  These shoes, however,  are long enough at the toe so that my "toe cleavage" doesn't show (I've got long, slim feet with long toes) and toe itself is squared off just enough.  They look great and I got lots of compliments on them.

BUT, even though I wore them around the house for days to help break them in and covered the inside heels as well as the over-the-toe section with foam "rub relief" strips, they rubbed terribly the first time I wore them to work.  The second time, I added more strips and band aids on the affected areas of my feet and it got even worse.  Even putting band aids on top of band aids didn't help, and I wasn't walking all over town, simply from the parking garage to my building and then in between two floors of my building.  For over a week after I had to wear sandals because my heels had been rubbed so raw.

I don't think it's the sizing; had I gone up a size they would have slipped from my heels with each step.  It may be that the stitching in the inside edges is too rough.  Maybe with very thin "peds" they could be wearable, but beware if you want to go barefoot in these.
