Charles Jourdan Paris Heels shoes pumps

they say size 10 but they fit like a 9 because I am a 10 and they are tight on my foot ro the point I cannot wear them so size 9 should be able to fit these. 3 inch heel, red bottom, pointed toe. Bought them from here and cannot fit them so selling and making the disclaimer that these do not fit me and I am a true 10.
