The STRUTZ PRO helps your feet by maintaining an arch for your foot.  It provides support and absorbs shock as you walk or run. We suggest a short break-in period such as wearing the STRUTZ PRO one hour the first day, two hours the next day and so on until you can wear it all day long. This allows your foot to get accustomed to wearing our product and causes the cushion pad to mold into a perfect arch support for you. Detailed instructions about how to use your STRUTZ  PRO are included with each purchase.
