Unfortunately for such a well known sandal, the entire side thong failed prematurely by pulling out of the rubber.  The sandals were nearly new and while used daily in normal conditions.  These were about $58 and seemed otherwise well made.  I trusted them as my only walking sandal in a recent trip to Nicaragua and was glad they didn't fail on a walk there as I would have had to limp home!<br /><br />Fortunately, amazon has provided a refund very quickly
