The size is 5.5. It's a Japanese 23cm, but the width is a bit narrow. It might fit well for those who wear 22.5cm or those who are slightly under 23cm, even with a thin insole. It has only been used 3-4 times and there are no noticeable stains or marks. How about it for this season, with skirts or slim pants? Material: Genuine leather #Ferragamo
