When men's shoe sizes get up past 13 they get a bit varied in their accuracy. In some shoes or brands I wear a 14 or 16, but 90% of my shoes are size 15, and these size 15s were accurate to that. Very comfortable shoe, and Amazon is the only place I've seen it in this size. (For reference, I wear size 15 in Adidas, Reebok, and New Balance sneakers, and 15 in Rockford and Sketchers dress shoes.)
