The wet foot test can help you determine if you are overpronating or have a more neutral gate. You should use a surface that will show water easily. Many people do this test at a swimming pool as you can usually see the steps you take with wet feet as you exit the pool. Take several steps with wet feet and analyze your foot prints. If there is no arch seen, you likely overpronate. If you have a higher arch, you underpronate. Somewhere in the middle would mean you have a neutral gait.
