These are "Moon Boat" leather shoes, size 23cm (pearl beige), purchased from Heinritz. The leather is soft and comfortable, but they are from a friend who can no longer wear the 7cm heels. The previous owner's name is faintly visible on the inside of the right shoe. As shown in photo 6, there is a small cut on the inside of the right shoe when opened with a finger. Would these be suitable for practice? I am also listing another, slightly newer pair of shoes. Please comment if you would like to purchase them together.
