These are shoes from Otto Bock, a comprehensive medical and welfare equipment manufacturer based in Germany. However, I don't know the specifics. Judging from the condition of the outsole, I don't think they've been used outdoors. There is no noticeable damage. The size is 37. I am 24cm, and they fit perfectly. Total length: Approximately 25.5cm x width: Approximately 9.5cm - Color: Brown - Design: Velcro strap - Material: Leather - Style: Casual shoes - Sole: Rubber sole These are used / long-term storage items. We have inspected them, but there may be minor damage that we have overlooked. If you are looking for a perfect condition or like-new item, please refrain from purchasing or bidding. Also, the actual color may look different depending on the lighting and the device you are using. Thank you for viewing. Color...Brown系
