PRO: I liked the lightness, the air circulation and the dirt-repellent sole (the pattern didn't allow small particles to become wedged in the sole). says they run a little bigger than the size says. I found just the opposite. I ordered the largest men's size they had, 13M. As I put them on barefoot I immediately noticed that they are about 1/2 small to normal sized for me. I cut out the leather trim at the very top of the boot which helped a little but prevented me from sending it back. My decision and I will live with it. 13M was the largest size listed by this vendor but I have seen 13.5 and 14M from others.
