These are enamel formal shoes. With the insole in, they are 18.5cm, and without it, they can be adjusted to 19cm. They have only been worn a few times for graduation and entrance ceremonies, so there are no noticeable stains or fraying. However, they are used items and have been stored at home, and as I am a private seller, there may be oversights. Please refrain from purchasing if you are looking for a perfect item. Please purchase only if you understand everything.
