Medium Fitting Shoes
A women's medium shoe will be marked as a B. The letter D is used for a wide shoe. Thus, the letter D for a man is medium while it is wide for a woman. Like men's shoes, not every shoe will be identical. A medium shoe for one company may, but another company may require a wide for the same fit.
Medium or Wide The difference between medium and wide shoes may not be that great but it is important. The correct size can be determined by the Brannock foot-measuring device. After a foot is placed on the device, it indicates what the proper width is for that foot. Even with this device, you need to try on shoes because they may not conform to the measurements.
Misconceptions The perception you have about your foot width is irrelevant to shoe width. Medium and wide shoes are different for each manufacturer, so the only way to know if a medium or wide shoe is appropriate is to try the shoe on.
