I love these because you get the comfort of a Sanuk with bit more formal look. (less hippie)
I have these in Red and I love them, a great summer shoe for me. I can't wear sandals to work as we have a no open toe dress code so these are great.
Breathable with a study rubber sole lets me longboard in them too.
As far as I can tell they run true to size, although my red pair fit perfect and ten I bought a black pair that were a tad tight, no in the toe but across the foot. I think that was a fluke though.
