this is a fantastic sandal.  I was looking for a open sandal that would provide great support for extensive walking (Disney here I come) while still allowing for the swelling that I get with overheated feet.  These easily adjust for the swelling while still being in the right spot for my arches and supporting my feet overall.  Fit was exact - usually wear a 8 in open shoes 8 1/2 for more closed shoes.  I have several pairs of the Teva Mush flip-flops and the footbed on this sandal is firmer than the mush but still soft enough to conform to the foot and be comfortable.  I also recommend their hiking and winter boots - Teva in general is a great brand for me especially as I have a "healed" stress fracture in my right foot that causes discomfort during weather changes and long days on my feet.
