How to Measure Your Feet

1

Trace your foot

Stand on a sheet of paper while wearing the socks you'll wear with the shoes, and trace the outline of your foot.

2

Measure the length

Measure from the back of the heel to the tip of your longest toe in inches or centimeters.

3

Match your size

Compare your measurement to the foot-length row in the chart above to find your size.

Fit Tips

  • Measure your feet at the end of the day, when they're at their largest, for the most accurate fit.
  • If one foot is slightly larger than the other, always go by the larger foot.
  • Between two sizes? Choose the larger size for roomier, all-day comfort.
  • For the best fit, wear the same type of socks you plan to wear with your new shoes.
