I'm a longtime Birk Arizona-loving person. I bought these for all the reasons given here: cheap, waterproof, lightweight, great for wet/dry conditions in the summer, etc. Got the same size I usually wear and they felt the same on my feet. However, after half a day, I had sore red blisters forming on both little toes from rubbing against the plastic upper strap. (Strap was on last hole, as usual) I live in a dry climate, at high altitude in New Mexico, so this was not due to summer humidity or sweaty feet. Things stay dry all day here. It was the rubber upper. I'll stick with my leather and suede Arizonas from now on. Wish I could return them, but wore them outside.
