A shoe-width chart allows shoppers to measure the width of their feet so they can purchase shoes that fit comfortably. Most shoe retail stores offer foot-sizing and width-measuring equipment for customers.
There are a variety of shoe-width sizes on a shoe-width chart, such as 2E for wide men's shoes or extra-wide women's shoes and 4E for extra-wide men's shoes. The standard width for women is a size B, while men average a size D. Most shoes display the wide and narrow widths under the tongue of the shoe.
Visible stretching or bulging of material near the forefoot is a good indicator that a larger width is required. In some cases, men need to wear women's shoe to achieve a narrow fit, and women need to wear men's shoe to achieve a wide fit. The usual differences between narrow, standard, wide and extra wide sizes are only a few millimeters and are proportional with the rest of the shoe.
If a customer's foot seems to fall between sizes, it is a good idea to purchase the larger size, as the difference can be compensated by socks, insoles or a different lacing pattern. Since feet tend to swell throughout the day, it is also important for customers to shop later in the day when their feet are largest;
