Normal Biomechanics of the Foot and Ankle

The biomechanics of the foot and ankle are important for efficient movement, stability, and shock absorption. During walking, the foot moves through a cycle that begins with heel strike, where the heel contacts the ground, absorbing impact and distributing force through the arch. As the foot rolls forward, it enters midstance, a phase where the entire foot bears weight, allowing for balance and stability. In the final push-off phase, the toes lift off, propelling the body forward. The ankle joint, connecting the foot to the leg, allows up and down movement, while the subtalar joint below enables side to side motion. Ligaments and tendons provide structural support, and the arch acts as a spring, storing energy with each step. Proper biomechanics ensure efficient movement, protect joints from excess stress, and reduce injury risk, maintaining foot health over time. It is suggested that you visit a podiatrist to have a foot and ankle examination and gait analysis to ensure you have proper biomechanics enabling optimum comfort and mobility.

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.

Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Symptoms and Causes of Tinea Unguium

Tinea unguium, also known as onychomycosis, is a fungal infection that affects the nails, particularly the toenails. This condition causes changes in the appearance of the nails, which may become thickened, discolored, and brittle. Infected nails can also separate from the nail bed, causing discomfort and potential pain. The primary cause of tinea unguium is the overgrowth of fungi, particularly dermatophytes, which thrive in warm and moist environments. Risk factors include wearing tight footwear, having a history of athlete's foot, and compromised immune systems. Poor hygiene can also contribute to the development of this infection. Recognizing the symptoms early is essential for effective treatment, as untreated cases can lead to more severe complications. If you have toenail fungus symptoms, it is suggested that you consult with a podiatrist who can offer you prescribed medication for effective treatment.
For more information about treatment, contact one of our podiatrists of Coastal Foot & Ankle Wellness Center, LLC. Our doctors can provide the care you need to keep you pain-free and on your feet.
Toenail Fungus Treatment
Toenail fungus is a condition that affects many people and can be especially hard to get rid of. Fortunately, there are several methods to go about treating and avoiding it.
Antifungals & Deterrence
Oral antifungal medicine has been shown to be effective in many cases. It is important to consult with a podiatrist to determine the proper regiment for you, or potentially explore other options.
Applying foot powder on the feet and shoes helps keep the feet free of moisture and sweat.
Sandals or open toed shoes – Wearing these will allow air movement and help keep feet dry. They also expose your feet to light, which fungus cannot tolerate. Socks with moisture wicking material also help as well.

Treating Toenail Fungus
Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening. The fungal infection itself occurs beneath the surface of the nail. Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail. If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk.
The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms. Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails.
Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes. Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential. Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.
Fungal nail treatment may vary between patients and the severity of the condition. Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections. Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications. Debridement, or the removal of diseased nail matter and debris, may also be performed. In more severe cases, surgical treatment may be needed. In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed. In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.
Walking Shoes for Optimal Comfort

Choosing the right walking shoes is vital for comfort and foot health. An important aspect is the lacing technique, as using methods like the heel lock can prevent heel slippage and enhance stability. Correct shoe size is equally as important, as shoes that are too tight or too loose can lead to blisters and discomfort. It is also essential to remember that shoes do not last forever, and regular replacement is necessary to ensure adequate support and cushioning. Additionally, the type of socks worn can significantly impact the overall experience as moisture-wicking socks can help prevent blisters and keep feet dry. Finally, athletic shoes are designed to provide the necessary support for various activities, including walking. Wearing the right shoes for your desired activity may help to prevent painful foot conditions. If you have foot pain and would like specific information about walking or running shoes, it is suggested that you consult a podiatrist who can provide relief and educational tips.
For more information about walking shoes versus running shoes, consult with one of our podiatrists from Coastal Foot & Ankle Wellness Center, LLC. Our doctors can measure your feet to determine what your needs are and help you find an appropriate pair of footwear.
Foot Health: The Differences between Walking & Running Shoes
There are great ways to stay in shape: running and walking are two great exercises to a healthy lifestyle. It is important to know that running shoes and walking shoes are not interchangeable. There is a key difference on how the feet hit the ground when someone is running or walking. This is why one should be aware that a shoe is designed differently for each activity.
You may be asking yourself what the real differences are between walking and running shoes and the answers may shock you.
Differences
Walking doesn’t involve as much stress or impact on the feet as running does. However, this doesn’t mean that you should be any less prepared. When you’re walking, you land on your heels and have your foot roll forward. This rolling motion requires additional support to the feet.
Flexibility – Walking shoes are designed to have soft, flexible soles. This allows the walker to push off easily with each step.

Walking Shoes vs. Running Shoes
Although walking shoes and running shoes look similar, they have characteristics that make them different from each other. Runners should avoid running in walking shoes and vice versa. It is very important that you wear the proper footwear for the activity you are going to partake in, for you to avoid injury.
If you are looking to buy a new pair of running shoes, there are certain things you should look out for. One of the main components that makes up a good running shoe is flexibility. You should be able to bend and flex the forefoot of the shoe that you are purchasing. If you can bend the entire shoe in half with ease, this is a sign that the shoe does not have enough structure for your feet. Another feature you should look for is a low heel. Certain running shoes have a low heel to support runners who land on the ball of their feet. Lastly, you should look for the fit of the running shoe. You should visit the best running shoe store in your area to have your feet properly sized for the shoes in the store. Usually, the staff will be able to help recommend the best type of running shoe for your needs.
When you are walking, the body’s weight is evenly distributed on the foot. This influences the design of shoes made for walking. If you are looking to buy a pair of walking shoes, there are different features you should look for to determine which pair of shoes is best for you. Walking shoes should be flexible through the ball of the foot to allow for a greater range of motion through the roll of the forefoot. These shoes also should have greater arch support for the foot. If you plan on walking long distances or on hard surfaces, it is best that you wear shoes that have cushioning.
When trying on a new pair of shoes, the heel should fit snugly without slip. You should shop for shoes after a long walk, since your feet tend to swell throughout the day. Many people have one foot that is a different size than the other, so it is best that you have both feet measured when looking for your true size. You should also beware that sizes vary depending on the shoe brand. A certain size in one brand may be a different size in a different brand. Lastly, you should always walk around in shoes that you plan on buying. This will help you determine whether the shoes are comfortable and if they fit well on your feet.
Always look for good shoe construction when shopping for new sneakers. The upper part of the shoe should allow for adjustment through laces or straps. If you need help with shoe sizing or if you need custom orthotics for your feet, you should make an appointment with your podiatrist for assistance. He or she will be more than happy to help you with your shoe sizing needs.
Are You Suffering From Ingrown Toenails?
Recognizing Foot Problems

Foot issues, such as plantar fasciitis, heel spurs, and claw toes, can significantly impact daily life. Plantar fasciitis is an inflammation of the plantar fascia, the thick band of tissue connecting the heel to the toes, causing sharp heel pain, especially in the morning. Heel spurs are bony protrusions that can develop on the heel bone, often linked to plantar fasciitis, leading to persistent pain and discomfort. Claw toes occur when the toe joints bend excessively, resulting in a claw-like appearance. Symptoms include pain, redness, and difficulty wearing shoes comfortably. Experiencing persistent symptoms warrant professional evaluation. A podiatrist might recommend custom orthotics, targeted exercises, or, in some cases, surgery to address the underlying issues. If you are experiencing foot pain or discomfort, it is suggested you schedule an appointment with a podiatrist for an accurate diagnosis and effective treatment options tailored to your needs.

Foot Pain
Our feet are arguably the most important parts of our bodies because they are responsible for getting us from place to place. However, we often don’t think about our feet until they begin to hurt. If you have pain in your feet, you need to first determine where on the foot you are experiencing it to get to the root of the problem. The most common areas to feel pain on the foot are the heel and the ankle.
Heel pain is most commonly attributed to a condition called plantar fasciitis. Plantar fasciitis occurs when the plantar fascia, which is the band of tough tissue connecting the heel bone to the toes becomes inflamed. Plantar fasciitis pain is usually worse in the morning, and it tends to go away throughout the day. If you have plantar fasciitis, you should rest your foot and do heel and foot muscles stretches. Wearing shoes with proper arch support and a cushioned sole has also been proven to be beneficial.
Some common symptoms of foot pain are redness, swelling, and stiffness. Foot pain can be dull or sharp depending on its underlying cause. Toe pain can also occur, and it is usually caused by gout, bunions, hammertoes, ingrown toenails, sprains, fractures, and corns.
If you have severe pain in your feet, you should immediately seek assistance from your podiatrist for treatment. Depending on the cause of your pain, your podiatrist may give you a variety of treatment options.
Erythromelalgia and Its Impact on the Feet

Erythromelalgia is a rare condition marked by severe burning pain, redness, and heat in the extremities, particularly affecting the feet. Individuals often experience debilitating symptoms that flare up in response to heat, exertion, or prolonged standing, leading to significant discomfort. The exact cause of erythromelalgia is not fully understood, but it is thought to involve abnormalities in blood flow and nerve function. This condition can affect people of all ages, but it is more commonly observed in adults, especially women. In the feet, erythromelalgia can hinder mobility and impact daily activities, making even simple tasks challenging. Understanding erythromelalgia is vital for those affected, as timely diagnosis and appropriate management strategies can help alleviate symptoms and improve overall quality of life. If you have any of the above symptoms, it is strongly suggested that you promptly consult a podiatrist who can help you to manage this condition.
Some foot conditions may require additional professional care. If you have any concerns, contact one of our podiatrists of Coastal Foot & Ankle Wellness Center, LLC. Our doctors can provide the care you need to keep you pain-free and on your feet.
Rare Foot Conditions
The majority of foot conditions are common and can be treated by a podiatrist. Standard diagnostic procedures are generally used to identify specific conditions and treatment can be rendered. A podiatrist also treats rare foot conditions which can be difficult to diagnose and may need extra attention and care.
There are many rare foot conditions that can affect children. Some of these can include:
- Freiberg’s disease
- Kohler’s disease
- Maffucci syndrome
Freiberg’s disease - This can be seen as a deterioration and flattening of a metatarsal bone that exists in the ball of the foot. It typically affects pre-teen and teenage girls, but can affect anyone at any age. Symptoms that can accompany this can be swelling, stiffness, and the patient may limp.
Kohler’s disease - This often targets the bone in the arch of the foot and affects younger boys. It can lead to an interruption of the blood supply which ultimately can lead to bone deterioration. The patient may limp or experience tenderness, swelling, and redness.
Maffucci syndrome - This affects the long bones in a child’s foot leading to the development of abnormal bone lesions. They are benign growths and typically develop in early childhood and the bones may be susceptible to breaking.
A podiatrist can properly diagnose and treat all types of rare foot conditions. If your child is affected by any of these symptoms or conditions, please don’t hesitate to call our office so the correct treatment method can begin.
