The sole is 7cm high at the heel. I purchased these from Classe over 10 years ago. No outer box. Please be aware that there is deterioration such as scratches, stains, and yellowing. The inside has been lightly wiped with a disinfectant sheet, but I haven't disassembled them, so please forgive any dust, etc. The dirt on the soles could not be removed. I think I bought them in size M, but they fit me snugly, and I am 23.5cm. I will ship via Kuroneko Yamato courier service, so if you have a preferred time slot, please let me know via DM after purchase (date and time cannot be specified). I can ship the day after your purchase, but I cannot accommodate those in a hurry.
