Orthotics

Heel Insert

For example, a wedge inserted into the inner (medial) side of the sole of a shoe can be used to help support a flatfoot, thus reducing the risk of tendinitis. An ankle-foot brace can help relieve the pain of rheumatoid arthritis in the heel or ankle. A heel flare can be used to increase support and help prevent ankle sprains. Heel cushions can help absorb impact and relieve stress on the heel and ankle when you walk or run. The type of orthosis recommended by your doctor will depend on your symptoms, the underlying cause for those symptoms, and the shape of your feet. In some cases, your doctor may prescribe an insert or pad; in other cases, modifications to your shoes may be necessary.

Although custom orthoses are considerably more expensive than off-the-shelf devices, they last much longer and provide more support or correction. In some cases, however, an over-the-counter device can be just as effective, particularly when combined with a stretching and exercise program. In the past, plaster molds of the foot were used to construct the custom-made orthosis. Now, computerized foot analysis is often used to develop orthoses that more accurately reflect the dynamics of your gait.

Diagnosis

Recommended Orthotic Device

Bunions and/or bunionettes

Shoes with a wide toe box; soft, seamless uppers, stretchy shoes; "bunion shield" type pad

Corns and calluses

If located on or between the toes, a toe separator may be helpful.

Cavus foot (rigid high arch)

Soft orthotic cushions to distribute pressures evenly

Flatfoot (adult)

No device needed if there are no symptoms or pain. If there is pain or aching, a semirigid insert or long arch pad, inner heel wedge or extended heel counter may help.

Flatfoot (child)

No special orthotic device or shoe treatment is indicated. Most infants have flatfeet, and 97 percent will grow out of it.

Stiff big toe (hallux rigidus)

Full-length prefabricated stiff insert, Morton extension inlay, or rocker bottom sole

Hammer toe or claw toe

Shoes with a wide or deep toe box to accommodate the deformity; toe crest

Forefoot pain (metatarsalgia)

Wide shoes, pads or bars under the bones of the forefoot (metatarsals)

Limb length deformity

Custom-made full-contact orthosis

Morton neuroma

Shoes with a wide toe box, metatarsal pad positioned over the neuroma

Neuropathic ulceration (such as with diabetes)

Full-contact cushioned orthosis, extra-deep or custom shoes, rocker bottom sole to reduce pressure on foot

Plantar fasciitis (heel pain or heel spur)

Prefabricated heel insert made of silicone, rubber or felt

Runner's painful knee

Full-length, soft, prefabricated sport orthotic inlay to reduce stress and turning inward of the foot (pronation; flatfoot)
