Of course, the length of your foot isn't the only criterion when picking your shoe size, and manufacturers might vary slightly. So remember to write your measurements (width and length) down in inches. That way, if you order shoes online, you can check your foot size in inches with that of each particular manufacturer's sizing chart.
If you want to be certain that the shoe will fit, and you can't try them on, you should have your foot measured by a professional and use those measurements to find the proper shoe.
