It typically takes about a week to acclimate to your custom foot orthotics for full-time wear. Here are some tips for the most effective way to adjust to them: Start by wearing your orthotics for one hour on the first day, then increase the wearing time by one hour each subsequent day—two hours on the second day, three hours on the third, and so on. You can wear them longer if you feel comfortable, or reduce the time if needed. If you experience pain before the time is up, remove the orthotics. Do not extend the wearing time the next day, but rather continue with your planned schedule the following day, increasing the duration by one hour daily.
