They have several pairs of Sperry Leeward and A/O shoes that are a size 12 and they fit the length perfectly (would like to be 12 1/2 if they made one ). I figured the trendier Gold Cup Line would probably be a bit smaller so I tried a size 13 and it was soooo big, bigger than most 13's I've tried. Too bad beautiful well made shoes. I would reorder a size 12 but that size was three times the price of a size 13.
