What is an Orthotic?
Foot Orthotics allow the muscles, tendons and bones of the feet through open and closed chain joint migration, up through the legs, hip and lower back, to function at their optimal potential for our body weight, structure, walking pattern and life styles.
When appropriately prescribed and more importantly, appropriately manufactured, Foot Orthotics can decrease pain and discomfort in the foot, ankles, knees, hips and back. Foot Orthotics increase our stability, prevent further progression of bony deformities, soft tissue pain, burning and numbness and help to improve our overall quality of life in our activities of daily living (ADLs).
Remember, foot pain is not normal and should not be ignored. The pain in our feet often is associated with other pains in our lower limbs all due to the poor inherent biomechanics of our foot.
With a foot orthotic supporting the three main arches of the foot the muscles and tendons are able to work within their intended range of motions (ROMs) and we do not run the risk of causing injury or furthering one.
Benefits of Orthotics
Custom Foot Orthotics help in providing relief for painful foot problems or an injury, especially for those who must walk, or stand excessively on the job or in every day activities.
The mechanical properties of the Custom Foot Orthotic help to maintain the normal positioning of the bones in the foot, the joints in the ankle and knees leading up to the hips and lower back. The muscles and ligaments holding these bones in their intended anatomical positions are prevented from over stretching and becoming lax over time.
With enough functional correction from a Custom Foot Orthotic, the foot structure can be aligned to give more propulsion, making walking, running and even cycling more efficient biomechanically.
Along with aligning the foot structure, the Custom Foot Orthotic reduces muscular fatigue and helps to promote more efficient muscle performance thus enhancing performance during the gait cycle.
Below is an example of a foot without the corrective support of an orthotic and then another example of the same foot with a Custom Made Foot Orthotic from POL correcting and supporting the foot. Notice the difference a well made Custom Foot Orthotic makes!
The Structure and Function of an Orthotic
Foot Orthotics are constructed from various materials consisting of plastics, foam, rubbers, and cork composites that are utilized for their mechanical properties.
The main similarity of all Foot Orthotics is the principle of their structure. The core is comprised of a plastic material more commonly referred to as the shell. External support structures on the underside of the shell material are utilized for balance and support inside the footwear; these are commonly referred to as extrinsic posts. Soft padding is placed on the underside and the topside to absorb compression forces when walking and running, this includes the top covers, underlay materials and arch fills.
All of these materials have the goal of improving foot function and minimizing the stress forces that cause foot deformity and pain.
Dependent on the reason for the prescription of Foot Orthotics, all of the above mentioned materials can be utilized in many combinations to achieve three broad categories of Foot Orthotics:
- Those that primarily attempt to change foot function, known as functional Foot Orthotics
- Those that are mainly protective or accommodative in nature, and
- Those that combine functional control with accommodation for comfort.

Warts
As always, you can contact our office to answer any questions or concerns.
Most foot warts are harmless, even though they may be painful. They are often mistaken for corns or calluses, which are layers of dead skin that build up to protect an area which is being continuously irritated. A wart, however, is caused by a viral infection which invades the skin through small or invisible cuts and abrasions. Foot warts are generally raised and fleshy and can appear anywhere on the foot or toes. Occasionally, warts can spontaneously disappear after a short time, and then, just as frequently, they recur in the same location. If left untreated, warts can grow to an inch or more in circumference and can spread into clusters of warts. Children, especially teenagers, tend to be more susceptible to warts than adults.
Plantar warts, also known as verrucas, appear on the soles of the feet and are one of several soft tissue conditions that can be quite painful. Unlike other foot warts, plantar warts tend to be hard and flat, with a rough surface and well-defined boundaries. They are often gray or brown (but the color may vary), with a center that appears as one or more pinpoints of black. Plantar warts are often contracted by walking barefoot on dirty surfaces or littered ground. The virus that causes plantar warts thrives in warm, moist environments, making infection a common occurrence in public pools and locker rooms.
Like any other infectious lesion, plantar warts are spread by touching, scratching, or even by contact with skin shed from another wart. The wart may also bleed, another route for spreading. Plantar warts that develop on the weight-bearing areas of the foot (the ball or heel of the foot) can cause a sharp, burning pain. Pain occurs when weight is brought to bear directly on the wart, although pressure on the side of a wart can create equally intense pain.
To prevent the spread of warts, follow these tips:
- Avoid direct contact with warts, both from other persons or from other parts of the body.
- Avoid walking barefoot, except on sandy beaches.
- Change your shoes and socks daily.
- Check your children's feet periodically.
- Keep your feet clean and dry.
It is important to note that warts can be very resistant to treatment and have a tendency to reoccur. Over-the-counter foot wart treatments are usually ineffective because their use can inadvertently destroy surrounding healthy tissue. Please contact our office for help in effectively treating warts. Our practice is expert in recommending the best treatment for each patient, ranging from prescription ointments or medications to, in the most severe cases, laser cautery.
