    Our unique sizing is unisex and based on a Centimeter scale; our size 9/10 means that the sandal is roughly equivalent to size 9 for men, and size 10 for women. Some people find our sizes run slightly small especially in our smallest sizes. If you are deciding between two sizes we typically recommend ordering the larger one.
