Supination and pronation are natural movements of the feet that occur during walking and running. Pronation refers to the inward rolling of the foot as it strikes the ground, helping absorb shock and distribute weight. Supination, also known as under-pronation, is the outward rolling of the foot, which places more pressure on the outer edge. Both motions are essential for balance and efficient movement. However, when either becomes excessive, it can lead to poor biomechanics and increased strain on the feet, ankles, and lower limbs.

Symptoms of excessive pronation often include flat foot posture, inward ankle rolling, and pain along the arch or inner ankle. Individuals may also experience knee or hip discomfort due to misalignment. Excessive supination typically presents with high arches, limited shock absorption, and pain along the outer edge of the foot or ankle. Repeated stress can lead to conditions such as ankle instability, stress fractures, or tendon irritation. These symptoms can worsen over time without proper support or correction.

Several risk factors contribute to abnormal foot mechanics. Genetics play a significant role, as inherited foot structure can influence arch height and alignment. Wearing incorrect footwear that lacks support or cushioning can worsen both pronation and supination. Bodily misalignment, including uneven leg length or poor posture, can also affect how weight is distributed through the feet. High impact activities and prolonged standing may increase stress on already imbalanced foot structures, leading to discomfort and injury.

Managing excessive supination or pronation involves improving support and correcting alignment. Wearing properly fitted, supportive footwear is essential for maintaining stability and reducing strain. Custom orthotics can help guide the foot into a more neutral position and improve overall biomechanics. Strengthening and stretching exercises may also support better movement patterns. If excessive supination or pronation of the feet is affecting your comfort or mobility, it is suggested that you consult a podiatrist for effective relief and management tips.

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.

Stretching the feet helps keep muscles, tendons, and joints flexible, making everyday movement easier and more comfortable. Healthy feet support balance, absorb shock, and help the body move efficiently while walking. As people age, the feet can become stiffer, reducing flexibility and increasing the chance of discomfort. Regular stretching helps maintain range of motion, which is the ability of a joint to move through its full motion. Stretching also supports better foot function and can improve stability. A podiatrist can evaluate foot flexibility and identify areas of tightness that contribute to pain or reduced mobility.

Several simple stretches improve flexibility in different parts of the feet. Toe stretches help maintain movement in the joints and reduce stiffness. Calf stretches improve flexibility in the muscles connected to the heel through the Achilles tendon. Rolling the foot over a small ball can gently stretch the arch and improve comfort. A podiatrist recommends stretches based on your foot structure, symptoms, and daily activities. Stretching works best when movements are slow and controlled rather than forced.  wearing shoes that lack proper support can increase strain on the feet, making flexibility even more important for comfortable movement. Regular stretching also helps prepare the feet for daily activities and supports better balance.

A podiatrist creates a stretching program that matches each patient's needs and goals. Treatment can also include custom orthotics and wearing supportive shoes to improve foot alignment and reduce stress on painful areas. Regular evaluations help monitor flexibility and identify changes before discomfort becomes more serious. Better flexibility can improve comfort, support healthier movement, and help the feet perform more efficiently throughout the day. Podiatric guidance also helps patients perform stretches correctly for the greatest benefit. If you have  foot pain or stiffness, it is suggested that you schedule an appointment with a podiatrist for additional guidance on effective foot stretches.

Stretching the feet is a great way to prevent injuries. If you have any concerns with your feet consult with Nadia Sadeghi, DPM from Lincoln Park Foot and Ankle Specialists. Our doctor will assess your condition and provide you with quality foot and ankle treatment.

Stretching the Feet

Stretching the muscles in the foot is an important part in any physical activity. Feet that are tight can lead to less flexibility and make you more prone to injury. One of the most common forms of foot pain, plantar fasciitis, can be stretched out to help ease the pain. Stretching can not only ease pain from plantar fasciitis but also prevent it as well. However, it is important to see a podiatrist first if stretching is right for you. Podiatrists can also recommend other ways to stretch your feet. Once you know whether stretching is right for you, here are some excellent stretches you can do.

• Using a foam roller or any cylindrical object (a water bottle or soda can will do), roll the object under your foot back and forth. You should also exert pressure on the object. Be sure to do this to both feet for a minute. Do this exercise three times each.
• Similar to the previous one, take a ball, such as a tennis ball, and roll it under your foot while seated and exert pressure on it.
• Grab a resistance band or towel and take a seat. If you are using a towel, fold it length wise. Next put either one between the ball of your foot and heel and pull with both hands on each side towards you. Hold this for 15 seconds and then switch feet. Do this three times for each foot.
• Finally hold your big toe while crossing one leg over the other. Pull the toe towards you and hold for 15 seconds. Once again do this three times per foot.

It is best to go easy when first stretching your foot and work your way up. If your foot starts hurting, stop exercising and ice and rest the foot. It is advised to then see a podiatrist for help.

Blisters are fluid-filled pockets that develop on the skin after repeated friction, pressure, or burns. On the feet, they commonly form when shoes rub against the skin, or when prolonged walking places stress on certain areas. Although many blisters are minor, they can become painful and make everyday activities more difficult. The skin covering a blister helps protect the underlying tissue while it heals, making proper evaluation important if the blister is large, painful, or shows signs of infection. Some people are more likely to develop foot blisters because of foot structure, medical conditions, or activities that place repeated stress on the feet. Identifying the underlying cause may help reduce recurring problems and support better overall foot health.

Symptoms of a foot blister often begin with soreness or a burning sensation before the fluid-filled pocket becomes visible. The affected area may feel tender and become painful while walking or standing. In some cases, the blister may fill with clear fluid, while others contain blood because of greater pressure on the skin. If the blister breaks, the exposed skin may become irritated and more vulnerable to infection. Redness, swelling, or drainage can indicate that additional medical attention is needed. Persistent or recurring blisters should be evaluated because they may be related to abnormal foot mechanics or ongoing pressure in the same location.

A podiatrist can diagnose the cause of recurring or painful foot blisters and recommend treatment based on the patient's individual needs. During an examination, the podiatrist evaluates the affected skin, foot structure, and walking pattern to determine why blisters continue to develop. Treatment focuses on relieving discomfort, protecting the skin, and addressing factors contributing to repeated friction or pressure. Early podiatry care may also help prevent complications and support healthier foot function. If you have painful or recurring foot blisters, it is suggested that you consult a podiatrist for an evaluation and appropriate treatment options.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Nadia Sadeghi, DPM of Lincoln Park Foot and Ankle Specialists. Our doctor can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often lead to pain.

What Are Foot Blisters?

A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.

How Do Blisters Form?

Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.

Prevention & Treatment

It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.

Bunions are a progressive foot deformity defined as a bony enlargement at the base of the big toe joint. This condition develops when the big toe gradually shifts toward the second toe, causing the joint to protrude outward. The misalignment places stress on surrounding tissues, leading to inflammation, discomfort, and changes in foot structure. Bunions can worsen over time, especially when contributing factors are not addressed early.

Common symptoms of bunions include swelling, redness, and joint stiffness at the base of the big toe. Pain often increases with walking, standing, or wearing tight fitting shoes. The skin over the bunion may become irritated due to friction, and the joint may feel tender or warm. As the condition progresses, individuals may notice difficulty with shoe fit, decreased range of motion, and changes in walking patterns.

Several causes and risk factors contribute to bunion formation. Genetics plays a key role, as inherited foot structure can predispose individuals to joint instability. Footwear is another major factor, especially shoes with a narrow toe box or high heels that place excessive pressure on the forefoot. Additional risk factors include flat feet, ligament laxity, and repetitive stress from prolonged standing or walking.

A bunion corrector is a supportive device designed to help improve toe alignment and reduce pressure on the affected joint. It works by gently guiding the big toe into a more natural position while providing cushioning and stability. Although it does not reverse the deformity, it can relieve discomfort and slow progression when used consistently. Benefits include reduced friction, improved comfort, and better foot positioning during daily activities. If you have bunions and want information about bunion correctors, it is suggested that you consult a podiatrist who can determine if this form of treatment is right for you.

If you are suffering from bunions, contact Nadia Sadeghi, DPM of Lincoln Park Foot and Ankle Specialists. Our doctor 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
