Have had Columbia sandals before and like the fit. I have a narrow foot and most sandals are to loose  for proper fit. These are by far the most comfortable ones I have owned. The arch is just enough to notice but not so much . Also the foot pocket as a whole is the best. From day one you feel as though they have been worn in for some time just for your foot. The heel area has a deeper cut out so as not to have your heel hanging off the backside as with standard sandals. You would not know the bottom tread side is flat. It has a very stable stance so foot does not roll because of flat sole . Quailty leather with nice tones of darker base. I wear a 10.5 and bought 1/2 size down to a 10 and they are perfect. Dislikes, none so far !
