I bought these, but I have a lot of similar sandals and haven't worn them, so they're unused! They're 22.5cm, but I usually wear shoes that are 23-23.5cm, so I think they'll fit someone who wears 23cm without any problems! 【NEOUS/NEOAS】 LANKE Sandals Product Number: 21093510002910 Size: 350 (22.5cm) Product Description These are modern-looking thong sandals. Made of a matte nylon material, these thong sandals have a moderate trendy feel. Unlike platform sandals, they are not overly fashionable and are easy to wear in town. Although they are flat sandals, they have a moderate volume that adds to your feet, making them a stylish accent for the coming season when outfits tend to be lighter. Color: Black
