The leather design looks very good. They are very comfortable once they are worn for a while. They do take a while to break-in, but well worth the wait.
Take the Smoke and wrap it up in leather and you've got the box top. Great leather look, and leather sole if very comfy. I love these sandals for everyday use. I would say, though, that since they are leather they tend to fit a bit snug at first untily you really wear them in.
