This is a gift, but I'm selling it because I don't use it. It's a popular Gyosan sandal these days. Great for everyday wear or the beach! Easy to clean, so it's convenient. The size is listed as L on the sandal, but If you have thicker feet, it should fit someone who usually wears around a 23.5cm size. If you have thinner feet, it should feel like an L size. Based on my personal experience, the length of the sandal itself is about the size of an M, and the thickness of the thong when you put your foot in feels like an L size. This is just my personal opinion, so please use it as a reference.
