Edith Black Leather Boots 7 1/2 with 3" Heel they will fit sz 8

These boots are so comfortable even though they have a 3" heel. They are leather with manmade sole. The boots are 15" in height and also 15" around the top of the boot, the calf area. I am a size 8 and they fit me even though the marked size is 7 1/2.
