This item was received from someone else. Therefore, the size tag on the inside is worn and I cannot confirm the size. I can barely see the number "6", but I'm not sure if it's correct. A person who wears 24cm shoes tried them on and there was about one finger's width of space at the heel, so I estimate the size to be around 25cm. Due to the above reasons, I am selling this item as [junk]. If you are interested and know how to check the size, please let me know how to measure it and I will try. Please feel free to comment if you have any other questions. :)
