ZARA Buckle Flat Rider Ankle Boots in black. Size is 36, which I believe is equivalent to 23-23.5cm. I usually wear 23.5cm, and these fit me perfectly, so I've set the size as 23.5cm (_ _). However, please understand that sizing can vary from person to person (_ _). There are some scuffs on the soles and the inside of the toes, and some wear as shown in the 6th photo. Please refrain from purchasing if you are concerned about this (_ _). Instant purchase is OK.
