EU41 Feels like a 27cm fit. I usually wear 26.5cm, and there's more than 5mm of extra space. The upper and strap are made of leather. The sides are a velvety fabric. Box included. Used only once. I went to the nearby supermarket. At that time, I thought, "If I wear these any longer, the space between my toes will hurt," so I gave up wearing them for outings, as I do a lot of walking. I think these are suitable for those who usually go out by car and only walk inside department stores or shopping malls. I bought them because I liked the design with the buckle, even though they are thong sandals. Thank you. Color...Black Stains, tears, or odors...None
