PLEASE READ BEFORE PURCHASING:
Huaraches are not made in half sizes. Since they are made out of leather, they will stretch out once broken into. They are true to size, so if you are a 7 stick with a 7, 8 stick with 8 and so forth.
8.5 get 8. They will fit snug, but will loosen up after wearing them a couple times. If you have a narrow foot and up size, you run the risk of them fitting too lose.
Exception: If you have a wide foot, size up. 7.5 get 8, 8.5 get 9.
