I now have 3 pairs of Sanuk sandals.  One pair are just  about worn out, I've always had difficultly in finding, not only sandals but shoes that fit.  I've only owned 1 other pair of sandals in my life time and they were custom made Socrates Sandals. My Sanuks did not require any kind of breaking in or stretching.  This summer I lived in my Sanuks, they're comfortable and can walk in them all day. Highly recommend them.
