New Nine West Blaha Flats in Black

READ DESCRIPTION, SHOES RUN SLIGHTLY LARGE. Selling new Nine West Blaha flats in black size US 8. Originally bought these on clearance, but they were too loose. I am normally a size 8, but I believe they are half a size to one size too large. Trying them on and walking around my apartment, my heel didn't come out completely but it did slide up and down. I believe these would fit someone who is a size 8.5. If you are a size 9 these might be too small.
