I really was hoping to like these, as they appear to be very nice thongs.  The width was a bit too narrow, and the size a bit too small.  Additionally, the arch support is aggressive...not a bad thing, but about 20% more than I think is comfortable.  I wear custom orthotics, so I'm used to arch support, but this pair was just too much.  I think they'd be much better a size larger, and a size wider, with about 20% less arch support.  Since the latter is not possible, they had to go back.
