Customized prescriptive orthotics are individualized inserts that are designed to control and support abnormal motion and stress in the feet and the kinetic chain. Typically made of molded plastic or carbon fiber each insert is built and designed for the needs of each individual. The feet are the base of the entire “kinetic chain” above it, connecting the foot, ankle, knee, hips, sacrum/pelvis, and low back. Abnormal motion such as pronation ( flat feet or fallen arches) or supination (high arches or a rigid foot) causes stress through the entire chain that results in injuries like bunions, shin splints, plantar fasciitis, knee pain, heel spurs, knee and hip arthritis, and even back pain. Prescriptive custom orthotics support and restore normal motion and may be the essential element in any corrective therapeutic plan.
