How to Buy Shoes Online and Get the Size Right

Shoe sizes are not the same from brand to brand, and returns take time. A few minutes of measuring before you order saves most of the guesswork.

Measure your feet

  1. Measure in the evening. Feet swell during the day, and evening measurements match how shoes feel when worn.
  2. Stand on a sheet of paper. Mark the heel and the tip of your longest toe, then measure the distance.
  3. Measure both feet. Use the longer one; most people have one foot slightly larger.
  4. Compare with the brand's chart. Use the length in inches or centimeters, not your usual size number.

Read the listing

  • Width: look for wide or narrow options if you usually need them.
  • Upper material: leather gives a little; synthetics stay the same.
  • Owner comments on fit: "runs small" or "runs large" repeated many times is worth acting on.

Before you wear them out

Try new shoes indoors on a clean floor first, so you can still return them if they rub or pinch.
