Shoe width is measured across the ball of the foot. Many people with foot discomfort are wearing the wrong width, not just the wrong length. Width measurements vary by manufacturer, and many shoes are only available in medium width.

How to Measure Your Foot

Place a piece of paper on a hard floor against a wall.
Stand on the paper with your heel against the wall.
Mark the longest part of your foot on the paper.
Measure the distance from the wall to the mark in centimeters or inches.
Use the measurement to find your approximate shoe size.

Tips for Accurate Measurement:

Measure both feet - most people have one foot slightly larger than the other.
Measure later in the day when your feet are at their largest.
Wear the socks you plan to wear with the shoes.
Stand when measuring, as your feet spread when bearing weight.
Allow about 3/8" to 1/2" (0.5-1 cm) of space between your longest toe and the end of the shoe.
