Bought a size 13 as several reviews mentioned it fit less. I decided I could have a little more room than being too tight; However, the sandals are about one size too narrow and about 2 sizes too small. The pads of my feet sag about 1/8 inch to the sides and the heel of my foot sags about 1/2 inch, that's when I take the time to actually squeeze my entire leg through the straps. I've heard great things about the brand from friends and family about their shoes. The sandals are back.
