Like regular street shoes, athletic shoe sizing is based on the length and width of your foot. Determining your proper shoe size is essential to a comfortable fit.

Fit Tips

  • Shoes that are too small are one of the major causes of foot pain and problems
  • Shoes that are too large can cause blistering and a lack of stability
  • Don’t assume your shoe size is the same as it always has been. The shape of your feet changes over time.
  • Not all brands of footwear fit the same. The below generic size guide is a good indicator on what shoe size you should wear, but some brands may offer slightly different sizing guidelines.

 

Measurement Tips

  • Take your measurements at the end of the day, when your feet are the largest
  • Wear the socks you’ll wear with your new shoes when you measure
  • Measure both feet and fit shoes to the larger foot
  • If you are doing the measurement by yourself, you will get more accurate results if you sit in a chair when measuring. Don’t stand.
  • If you have someone to help you take your foot measurement, standing is the best choice
  • You may take measurements in inches or centimeters. To convert inches to centimeters, multiply inches by 2.54.

 

How to Measure Your Foot

 

  • While seated, place your foot on a piece of paper in front of you
  • With a pencil, trace around your foot. Hold the pencil as straight up-and-down as possible while measuring and be sure that your pencil remains in constant contact with your foot during this process.
  • With a ruler, measure your tracing to determine your foot length and width
    • Foot length
      • To find your foot length, measure the distance between the two longest points on your tracing. Reduce this number by 5 mm, or 1/5-inch. The result is your foot length and the number you will use to determine your shoe size.
      • To convert to centimeters, multiply the measurement by 2.54.
    • Foot width
      • To find your foot width, measure the distance between the two widest points on your tracing. Reduce this number by 5 mm, or 1/5-inch. The result is the number you will use to determine your foot width. Use the chart below to determine your foot width.
