【U.S. POLO ASSN. / U.S. Polo Assn.】 One Point Thong Sandals Black / 27.0cm Purchased on ZOZOTOWN. Selling because the size was too small, and there are no larger sizes available. The size is 27.0cm, but it felt tight on my feet, and I usually wear 26.5cm. I think it will be tight for those who wear 26cm or larger, or those with high insteps. I've attached an image of the size on the inside for reference. I only tried them on indoors, so they are in near-new condition, but please understand that they are still used items.
