Coach Wiley Genuine Leather Pumps

lightly worn coach leather Wiley pumps in 100% genuine black leather. They are labled as a 7.5 which is what I normally wear but they were too large and I missed the return date. My foot is 23cm and im supposed to be a 6.5 but I prefer 7.5. you can see how far the heel is from mine so a miss on my end.
