As a chiropractor who treats mainly back disorders, I can tell you the foundation of your body, your feet, are critical to back health. If your arches drop, your feet and knees roll in, putting wear and tear on the medical meniscus (the portion of the knee most likely to form arthritis) and stress on the lower spinal discs. This can lead to disc prolapses and herniations, as well as arthritis and degeneration. Patients who purchase orthotics show a much greater recovery from knee and lower back conditions. Even neck problems can improve with the simple addition of orthotics. In my opinion orthotics are absolutely mandatory for patients with Plantar Fasciitis, heel spurs, bunions or hammer toes. Florence Chiropractic Center sells PowerStep, which are non-custom orthotics, ranging from $30-40. They are an easy and affordable way to see if orthotics make a difference in your pain.
