These are Dr. Martens leather shoes. They are not the classic three-hole style, but a unique model from the time when Dr. Martens were used by the British Post Office. As shown in the fourth photo, it says "royal mail" in thin letters, indicating they are vintage. I purchased them at a used clothing store for about 16,000 yen. The size is 6.1/2. They should fit well for those who wear UK size 7 in the 3-hole style. The actual outsole measurement is 28cm. Please only purchase if you understand that these are used/vintage items.
