Use the following tests to determine your foot pattern and help you select the proper shoes.
Method I:
Examine the wear pattern on the outsoles of an old pair of your shoes.
Normal Pattern: If about half of your arch is showing in the pattern, you probably have a normal foot pattern.
Normal Pattern: A wear pattern from the outside edge of the heel of the outsole toward the center of the outsole at the forefoot indicates a normal pattern. The majority of people have a normal foot pattern.
Overpronation Pattern: If your whole foot is outlined on the surface, you likely are an overpronator.
Overpronation: Excessive wear on the inside edge of the outsole of the shoe indicates overpronation or “flat feet.” The overpronation footpattern is more common than the excessive supination pattern.
Supination Pattern: If little or none of the middle of the food is outlined on the surface, you likely have the supinator pattern.
Supination: Excessive wear on the outside edge of the outsole indicates underpronation or the supinator pattern.
Method II:
Get your foot wet, and with your entire weight, step on a brown grocery bag or some other surface where you can see your foot print.
