Foot orthoses (also known as “orthotics”) are custom
foot supports. They are designed to fit your feet more efficiently than
over-the-counter (OTC) arch supports, and balance the biomechanical
inadequacies of your feet and legs. I feel most people should try OTC arch
supports first, but like a bell-shaped curve, they will match some peoples’
arches, and for others the support may be too high or low, or too far back
or forward.
The most common reasons people use foot orthoses are
for arch and heel pain (Plantar Fasciitis), lower leg tendonitis (Achilles,
Posterior Tibial Tendon and “shin splint” conditions) and for knee pain,
such as Chondromalacia Patellae, Iliotibial Band Syndrome and Runner’s Knee.
Foot orthoses are made from casts or scans of the feet, and incorporate
measurements of your foot and legs, limb length assessment, along with your
exact medical condition.
Most patients benefit from a thermoplastic device, but
the flexibility and rigidity can be varied by the prescription. Most foot
orthoses will last 5-10 years, and need to be changed if outgrown by 1 ˝
shoe sizes, or you have trauma, surgery or arthritis of your feet. Some
insurance companies (not all) cover part of the cost of treatment. The
devices may need to be recovered every 2-4 years which can be often done
locally at a cobbler or orthopedic shoe technician.
You should gradually use your new foot orthoses adding
a few hours a day, but some people adapt very quickly. Regardless, you
should not use them for extended activity, including sports until fully
comfortable. Sometimes you can develop blisters; you can apply Vaseline to
hotspots or friction areas. The devices should be comfortable and used
whenever you are doing the activity that would normally aggravate your
condition. However, it is beneficial to also go barefoot for some period
during the day when you are “healed” from the aggravating condition to aid
in strengthening the foot & leg muscles. If needed, foot orthoses should be
beneficial to your overall lower extremity comfort.
