Many children have flat feet but have no joint pain, but there are others who develop knee and/or arch pain that limits their ability to enjoy activities. If there is pain, and an obvious fallen arch, foot orthotics may be warranted considering family history and degree of severity. If there is no pain, yet there is an obvious fallen arch then the question is whether to correct or not. Many medical professionals believe that fallen arches will adversely affect the knees and hips and lead to early arthritic pain. Correcting the foot posture early on is then seen as a preventative measure for future knee and hip joint health.
