If you suffer from back pain or foot pain, you’re certainly not alone. Orthotics are a very hot market, and for great reason. One of the most common problems is overpronation, which is also known as flat footedness (although one’s arch does not need to be completely flat for this to pose a problem).
When you overpronate, your knees point inward, which creates even more alignment issues (hips, etc.), leaving your body prone to injury. Orthotics work by “motion control,” which is essentially providing support to the interior of the foot, keeping it from rolling inward.
