I have a narrow size 12 foot and actually double checked my size and they measured just under a 12 at a shoe store before ordering these shoes. So I ordered the 12s. I tried wearing one pair for a couple days and realized they were not going to work out. Learned mistake, I guess if I'd ordered 13s they would have fit nice and I think they would have been very comfortable. Oh well live and learn and I will be sending both pairs back.
