FOREVER21 Women's Thong Sandals, Black & Beige FOREVER21 Women's Thong Sandals Flat Sandals Thong Sandals These sandals are very stylish with the straps that wrap around the foot. My foot size is 24.5cm, and the size was perfect, but I couldn't fasten the straps around my ankles because they were too thick, so I'm selling them. There is no size notation, but I think they are 24-24.5cm. They are used, but in very good condition.
