I bought these after having worn my old size 39 Sanita clogs pretty much to death.  They were comfortable, durable, fit perfectly from the second I bought them, and looked good.  I thought that buying these would be a no-brainer.<br /><br />When they arrived, they were -- and remain -- insanely tight over the instep, as if the instep were made for a shoe that is two sizes smaller.  The foot and toe box are fine so going up a size would solve nothing but to make my foot rattle around like a pea in a jar, but the instep renders them nearly unwearable.  I have narrow feet already, so I haven't a clue who on Earth could actually wear these things.<br /><br />I'm going to buy some rubbing alcohol and see if stretching the insteps overnight won't improve things, but I'm really unbelievably disappointed at having blown over a hundred bucks on a pair of shoes that may well end up in the trash heap.  If you have worn old Sanitas at any point in the past -- DO NOT BUY THESE SHOES WITHOUT TRYING THEM ON IN PERSON.  There is an excellent chance you will not be able to wear them for more than about fifteen minutes.
