Making sure that you are wearing the right size shoe is a basic for daily comfort. 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. Also, just because you knew your shoe size a few years ago doesn't mean it is the same feet, like people, change over time.

The best time to measure your feet with the following method is at the end of the day, when your feet are at their most swollen.

Just follow these steps:

• Tape the paper down to the floor.
  
  
• At the end of the day when your feet are at it's  largest, place your foot, naturally stretched, on the paper. For more accurate results, sit on a chair with your foot firmly on the floor, and your leg bent slightly forward so that your shin is slightly in front of your ankle.
  
  
• With the pencil in an upright position and perpendicular to the paper, mark the back of your heel and the tip of your longest toe and then trace the outline of your foot. Remember to wear the socks that you will wear with your new shoes when you measure.
  
  
• With the ruler, measure the distance between the two longest points on your tracing. The result is your foot length and the number that you will use to determine your shoe size. To convert inches to centimeters, multiply inches by 2.54.
  
  
• Repeat these steps for your other foot, and use the larger of the two.
  
  
• Once your measurements are done, match it with the corresponding size.
