I purchased these Birkenstock shoes at a Birkenstock store in Germany and wore them 3-4 times, but they are a bit too big, so I'm selling them. The leather is very clean, but there is a small scratch on the toe of the right shoe. The soles will be even cleaner if cleaned. This size is sold out on the official website. 36inch, 23.0cm, Regular width (not narrow) Birkenstock's professional shoe, the QO400, provides a secure hold even in harsh work environments where you stand or walk for long periods, and the replaceable footbed effectively relieves stress on your feet. The QO400, which doesn't require laces, is a simple slip-on model. This outsole, which is slip-resistant and oil-resistant, firmly removes the load on the heel. The water-repellent smooth leather (WRU) upper protects the wearer from static electricity. This shoe is EN ISO 20347:2012 certified and meets the requirements of protection class O2.
