I just got a pair of Chaco Z/1 Yampa Sandals. I don't like these sandals at all. The rear straps bumps of sandals dig into my heels. I returned the sandals fo the wide size and they were just as bad as the regular width. It looks like Chaco's has molding problem where the sandal distorts after it is removed from the mold. I would not reccomend these sandals. My feet are a normal width and I have major problems. I wanted these to work so badly. I have the chacko flips and love them. They have been around the world at least 5 times and alway provided comfort and protection. The Z/1's were a big disapointment.<br />MM
