Theory Twisted Sandal in Black Leather. Size 40. This slide has twisted leather straps. Square toe silhouette. 100% calf leather. Crafted in Italy. This shoe ran small. I wear between an 8.5 and 9 M US and these fit. I purchased these from Theory.com (not outlet). They are in very good condition. If you have any questions, please let me know. We are a clean, smoke free home.
