Worn once! I typically wear 7.5/8 for sandals and 8/8.5 for shoes. I sized up to 9 which was WAY too big for me! I would say these are true to size. I do not have the original box. From the website: The Paonia Clog is your everyday essential. We kept our signature LUVSEAT™ footbed to ensure the same comfort of a Z/Sandal, but added a closed-toe silhouette. The upper material is a low nap suede that gives off a casual vibe, but can still be dressed up when the occasion arises. A rubber outsole and PU midsole provides traction and support for all day wear. The Paonia Clog is ready to be worn every day of the week. UPPER: Waterproof suede upper Adjustable polyester jacquard webbing with injection molded ladder lock buckle Soft textile lining MIDSOLE: Women's-specific LUVSEAT™ PU midsole OUTSOLE: Non-marking ChacoGrip™ rubber compound 2.5 mm lug depth
