I bought these for my husband for a recent vacation. We both loves the Teva sandals and my husband wore his last pair out believe it or not.  They are so comfortable and usually required no breaking in however this last pair gave him a blister. He normally wears a slip on sandal without a back so I kinda think because he has basically been without shoes this summer other than slides may just be the reason. As of a week later...comfort all around! A great sandal for comfort as well as casual style.
