When treating foot and ankle problems, commonly external devices are necessary to decrease pain and correct misalignments. These external devices are called Orthotics. When someone develops foot and/or ankle pain the problem is often from changes in walking pattern and ultimately changes in foot structure. The orthotic is a device capable of controlling motion in the foot and leg by maintaining the foot in or close to its neutral position. An orthotic conforms to all contours of the foot and is sufficiently rigid to maintain a proper arch.
