Measure Your Feet

Serious about getting the perfect fit the first time around? Measure your feet. While you could visit a shoe store and have a salesperson do it for you, it's easy to do yourself. First, make sure you're standing on a flat surface. Then, trace the outline of your foot on a piece of paper. Keep your pen as perpendicular to the paper as possible to produce the most accurate outline. On the tracing you've created, use a ruler to measure from edge of your heel to the tip of your longest toe.

How to Shop for Shoes Online

If you're buying shoes online, keep these tips in mind:

  • Always check the retailer's return policy for any shoes you buy.
  • These measurements don't take into account the thickness or width of your foot, so check if the shoes come in varying widths. These are usually denoted by "AA" (narrow), "B" (average), "C/D" (wide), or "E" (extra wide). Additionally, you might see "M," indicating a "medium" width.
  • Consider the socks you plan to wear, if any. They can take up room and make shoes feel tighter.
  • No two feet are exactly the same size—measure them both and use the larger measurement.
  • Feet tend to swell a bit as the day goes on, or after you stand on them for a while. Measure your feet when they're at their largest.
  • Consider the materials, manufacturing techniques, embellishments, and other factors that can affect the way a shoe fits.
  • Check the reviews for the shoes you're considering and look for comments regarding how true to size they run.
