Rag & Bone Engineer Boots Leather Boots Silver Buckle Size 36 (approx. 23cm) These are Rag & Bone engineer boots. They are made of black leather, making them easy to pair with skirts or pants. I purchased them in NY. They show signs of use, but I don't see any noticeable stains. The soles have rubber applied, but the heel parts are as they are. I've disposed of the box and dust bag, so there are no accessories.
