This is my second pair of these sandals. They are very comfortable, even walking for long periods of time. The straps do not cut into your feet at all, and no part of the sandal creates blisters.
These sandals are incredibly durable. I have put them through much abuse, and yet they look nearly as they did when I got them. The leather seems to be scratch resistant, if not nearly scratch-proof.
I would advise against buying cheaper imitations from GAP, AE, etc. They are of cheaper build and will not last as long. Many imitations do not have the embedded cork which, I feel, is largely responsible for the comfort of these sandals.
