Rigid Orthotics
The so called rigid orthotic device, designed to control function,
may be made of a firm material such as plastic or carbon fiber, and is used primarily for
walking or dress shoes. It is generally fabricated from a plaster of paris mold of the
individual foot. The finished device normally extends along the sole of the heel to the
ball or toes of the foot. It is worn mostly in closed shoes with a heel height under two
inches. Because of the nature of the materials involved, very little alteration in shoe
size is necessary.
Rigid orthotics are chiefly designed to control motion in two major foot joints, which lie
directly below the ankle joint. These devices are long lasting, do not change shape, and
are usually difficult to break. Strains, aches, and pains in the legs, thighs, and lower
back may be due to abnormal function of the foot, or a slight difference in the length of
the legs. In such cases, orthotics may improve or eliminate these symptoms, which may seem
only remotely connected to foot function.
