Normal foot and ankle biomechanics describe how the bones, joints, and ligaments work together during movement. Healthy biomechanics allow the foot to absorb impact, adapt to different surfaces, and provide stability when needed. During weight-bearing activities, the feet support the body while distributing pressure across the heel, midfoot, and forefoot. Proper alignment and controlled movement help reduce unnecessary stress on the lower extremities and support efficient walking, standing, and exercise.

Walking follows a coordinated sequence that begins when the heel contacts the ground and continues as the body moves forward over the foot. The ankle and foot gradually adjust to absorb impact before becoming more stable for push-off. Muscles and tendons provide control throughout this process. If alignment, flexibility, or joint motion is altered, certain areas may experience increased pressure. These changes can contribute to discomfort, overuse injuries, or changes in walking patterns.

Running places greater demands on foot and ankle biomechanics because the body experiences increased impact and faster movement. The foot must absorb force and then become stable enough to help propel the body forward. Risk factors for abnormal biomechanics include previous injuries, muscle weakness, and limited flexibility. Structural differences, improper footwear, and sudden increases in activity may also be factors. Symptoms of a biomechanical problem may include persistent foot or ankle pain, uneven shoe wear, or discomfort during weight-bearing activities.

A podiatrist can evaluate biomechanics by observing walking and running patterns and examining foot alignment, joint movement, and weight distribution. The foot doctor may also recommend supportive shoes, orthotics, or activity changes when appropriate. Follow-up visits can help determine whether treatment is improving movement and reducing stress. Understanding foot mechanics can support injury prevention and better mobility. If you have foot or ankle pain and want to understand your foot biomechanics, it is suggested that you consult a podiatrist for an accurate diagnosis and appropriate treatment.

Biomechanics in Podiatry

Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.

A History of Biomechanics

• Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
• In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.

Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.

Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Plantar fasciitis develops when the thick ligament on the bottom of your foot, called the plantar fascia, becomes irritated from repeated stress or strain. This strong band of tissue absorbs shock and supports the arch while walking, running, and standing. Tiny tears can develop when too much pressure is placed on it, leading to pain and inflammation. The most noticeable symptom is sharp heel pain with the first few steps after getting out of bed. Pain can also return after sitting for a long time or after spending hours on your feet. Plantar fasciitis can affect one or both feet, making everyday activities more difficult and limiting comfort while walking.

Several factors increase the risk of plantar fasciitis. These include repeated impact from running, standing for long periods of time, and carrying excess body weight. Shoes that lack proper support can also place added strain on the plantar fascia. A podiatrist performs a careful examination of your foot to identify the source of heel pain and rule out conditions with similar symptoms. Diagnostic imaging, like X-rays or ultrasound scans can help confirm the diagnosis. Treatment focuses on reducing inflammation, relieving pain, and improving foot function. Custom orthotics can improve arch support and reduce stress on the plantar fascia. Targeted exercises can improve flexibility and strengthen the muscles that support the foot.

Ignoring persistent heel pain can allow the condition to become more difficult to treat and interfere with work, exercise, and daily activities. Early care also lowers the chance of developing long-lasting pain that affects normal movement. A podiatrist can recommend stretching exercises that improve flexibility in the plantar fascia and calf muscles, helping to reduce strain on the ligament. The goal is to restore comfort, improve mobility, and help patients return to normal activities with less pain. If you have symptoms of plantar fasciitis, it is suggested that you schedule an appointment with a podiatrist for an accurate diagnosis and appropriate treatment.

Plantar fasciitis is a common foot condition that is often caused by a strain injury. If you are experiencing heel pain or symptoms of plantar fasciitis, contact Paul Potach, DPM from Illinois . Our practitioner can provide the care you need to keep you pain-free and on your feet.

What Is Plantar Fasciitis?

Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is a ligament that connects your heel to the front of your foot. When this ligament becomes inflamed, plantar fasciitis is the result. If you have plantar fasciitis you will have a stabbing pain that usually occurs with your first steps in the morning. As the day progresses and you walk around more, this pain will start to disappear, but it will return after long periods of standing or sitting.

What Causes Plantar Fasciitis?

• Excessive running
• Having high arches in your feet
• Other foot issues such as flat feet
• Pregnancy (due to the sudden weight gain)
• Being on your feet very often

There are some risk factors that may make you more likely to develop plantar fasciitis compared to others. The condition most commonly affects adults between the ages of 40 and 60. It also tends to affect people who are obese because the extra pounds result in extra stress being placed on the plantar fascia.

Prevention

• Take good care of your feet – Wear shoes that have good arch support and heel cushioning.
• Maintain a healthy weight
• If you are a runner, alternate running with other sports that won’t cause heel pain

There are a variety of treatment options available for plantar fasciitis along with the pain that accompanies it. Additionally, physical therapy is a very important component in the treatment process. It is important that you meet with your podiatrist to determine which treatment option is best for you.

A bunion forms when the big toe begins to angle toward the other toes, and the long bone behind the joint shifts outward. This change creates a noticeable bump along the inside of the foot. Bunions can run in families, and extra movement within the foot joints can contribute to their development. Wearing narrow or pointed shoes and high heels can make bunions progress more quickly. Some bunions cause little discomfort, while others become painful enough to limit walking and other activities. The size of the bump does not always match the amount of pain a patient feels.

Bunion pain can become stronger when shoes press or rub against the enlarged joint. A podiatrist can examine the foot and assess the position of the big toe to diagnose the problem. Imaging can also help rule out other causes of pain or provide details when surgery is being considered. Treatment depends on the patient’s symptoms and how much the bunion affects movement. Wearing wide-fitting shoes can reduce pressure against the bump. A podiatrist can also recommend cushioning pads or specialized insoles to reduce discomfort and improve support while walking.

Non-surgical care can reduce bunion pain, but it cannot permanently correct the changed shape of the joint. A podiatrist can study the way a patient stands and walks to determine whether an orthotic, which is a specialized shoe insert, could improve comfort. For severe pain, other treatments can be considered based on the patient’s needs. Surgery is the only treatment that can correct the bunion’s shape and can be considered when pain limits activity despite appropriate care. A podiatrist can explain the available choices and help patients understand which approach fits their symptoms. If you have developed a bunion, it is suggested that you schedule an appointment with a podiatrist for effective relief and treatment solutions.

If you are suffering from bunions, contact Paul Potach, DPM of Illinois . Our practitioner can provide the care you need to keep you pain-free and on your feet.

What Is a Bunion?

A bunion is formed of swollen tissue or an enlargement of boney growth, usually located at the base joint of the toe that connects to the foot. The swelling occurs due to the bones in the big toe shifting inward, which impacts the other toes of the foot. This causes the area around the base of the big toe to become inflamed and painful.

Why Do Bunions Form?

Genetics – Susceptibility to bunions are often hereditary

Stress on the feet – Poorly fitted and uncomfortable footwear that places stress on feet, such as heels, can worsen existing bunions

How Are Bunions Diagnosed?

Podiatrists often perform two tests – blood tests and x-rays – when trying to diagnose bunions, especially in the early stages of development. Blood tests help determine if the foot pain is being caused by something else, such as arthritis, while x-rays provide a clear picture of your bone structure to your provider.

How Are Bunions Treated?

• Refrain from wearing heels or similar shoes that cause discomfort
• Select wider shoes that can provide more comfort and reduce pain
• Anti-inflammatory and pain management drugs
• Orthotics or foot inserts
• Surgery

Some rock climbers assume that foot pain is simply part of the sport. It is true that climbing places stress on the feet and ankles. Small footholds concentrate body weight on an area, while down-turned climbing shoes hold the toes in a curled position. Falls can twist the ankle or force the foot against the wall. These demands can lead to heel pain, toe-joint irritation, or an ankle sprain. However, pain and injuries can also be related to the shoes worn. Sharp pain, numbness, or soreness that continues after removing climbing shoes should not be ignored. 

Several injuries deserve attention. Pain behind the heel can involve the Achilles tendon, which connects the calf muscles to the heel bone. Pressure from a climbing shoe can contribute to a tender bump at the back of the heel. Pain under the heel can result from irritation of the thick tissue supporting the foot. Tight shoes may push the big toe inward and irritate its joint. An ankle sprain can leave the joint swollen, weak, or unstable. Continued climbing with pain can affect technique and place greater stress on other body parts.

A podiatrist can determine which part of the foot or ankle is injured and identify contributing factors. An evaluation includes a foot-and-ankle examination, a review of climbing habits, and an assessment of walking and balance. Imaging can show a fracture or other damage when there is concern. Treatment includes supportive padding, a brace, or a custom orthotic that improves foot position in everyday shoes. A podiatrist can recommend climbing-shoe features suited to the patient’s foot shape and provide guidance for returning safely. Serious fractures, torn tendons, or unstable joints sometimes require surgery. Prompt care can limit further damage and support a comfortable return to the sport. If you have foot or ankle pain from climbing, it is suggested that you schedule an appointment with a podiatrist for a diagnosis and appropriate treatment.

Sports related foot and ankle injuries require proper treatment before players can go back to their regular routines. For more information, contact Paul Potach, DPM of Illinois . Our practitioner can provide the care you need to keep you pain-free and on your feet.

Sports Related Foot and Ankle Injuries

Foot and ankle injuries are a common occurrence when it comes to athletes of any sport. While many athletes dismiss the initial aches and pains, the truth is that ignoring potential foot and ankle injuries can lead to serious problems. As athletes continue to place pressure and strain the area further, a mild injury can turn into something as serious as a rupture and may lead to a permanent disability. There are many factors that contribute to sports related foot and ankle injuries, which include failure to warm up properly, not providing support or wearing bad footwear. Common injuries and conditions athletes face, including:

• Plantar Fasciitis
• Achilles Tendinitis
• Achilles Tendon Rupture
• Ankle Sprains

Sports related injuries are commonly treated using the RICE method. This includes rest, applying ice to the injured area, compression and elevating the ankle. More serious sprains and injuries may require surgery, which could include arthroscopic and reconstructive surgery. Rehabilitation and therapy may also be required in order to get any recovering athlete to become fully functional again. Any unusual aches and pains an athlete sustains must be evaluated by a licensed, reputable medical professional.
