Size M (22.5cm~23.5cm) * Elegant patent urethane sandals. * The thong is softer than traditional sandals, making them less likely to hurt even if you're not used to wearing them. * The sole is made of urethane material, so you don't have to worry about water seeping in even if you wear them on a rainy day. I have only used them once, but I am selling them because I no longer have the opportunity to wear them. * Returns are not accepted. Thank you for looking.
