CHLOE Black Perforated Leather Lauren Scalloped Ballet Flats Sz *see discription

CHLOE Black Perforated Leather Lauren Scalloped Ballet Flats Bottom of these shoes are very worn to the point that I cannot read the size. Inside measurement from tip of toe to heal is 10 1/4 inches. Those measurements equal up to a size 9. I have read that this particular shoe runs big so Im thinking it may fit more like 9 1/2. I would measure my foot from toe to bottom of heel to make sure that they will be a good fit. Bottom is very worn with a added heel step and toe step but rest of shoe and leather are really in great condition. Comes from a smoke-free home. Retail cost is $595.
