Understanding Types of Pronation

Pronation is the natural inward rolling motion of the foot during walking or running, which allows the arch to absorb shock and distribute body weight efficiently. There are three main types of pronation that influence how pressure moves through the foot. Neutral pronation is when the foot rolls inward slightly, helping to maintain balance and reducing stress on the ankles and knees. Overpronation happens when the foot rolls inward excessively, often in people with low arches or flat feet, which can lead to heel, arch, or ankle pain. Underpronation, or supination, occurs when the foot rolls outward, placing stress on the outer edge of the foot and increasing the risk of ankle sprains or heel pain. A podiatrist can evaluate your gait, foot posture, and arch type to determine your pronation pattern and recommend corrective devices, supportive footwear, or, in severe cases, surgery. If you experience foot pain or gait problems, it is suggested that you make an appointment with a podiatrist for a diagnosis and treatment options.

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.

The Importance of Biomechanics in Podiatry
Biomechanics and its related study deal with the forces that act against the body and affect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot, as well as the forces that impact them. Podiatrists who train in this specialty are able to effectively diagnose and treat conditions that affect people’s everyday movement.
Regardless of your lifestyle, age, or any other factors, many people experience foot problems throughout their lives. Twists and turns, improper balance, and added weight are just a few of the things that can add stress to the feet. These issues can also limit our bodies’ mobility that we often take for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

The history of studying biomechanics dates back to ancient Egypt at around 3000 B.C., where evidence of professional foot care has been recorded. Throughout the centuries, advances in technology, science, and an understanding of the human body led to more accurate diagnosis of conditions such as corns for example. In 1974, biomechanics garnered a large audience when Merton Root founded Root Lab to make custom orthotics. He proposed that corrections of certain conditions could be implemented to gain strength and coordination in the area. Due to his research, we still use his basic principle of foot orthotics to this day.
As technology has improved, so have the therapeutic processes that allow us to correct deficiencies in our natural biomechanics. Computers can now provide accurate readings of the forces, movements, and patterns of the foot and lower leg. Critical treatment options can be provided to patients now who suffer from problems that cause their biomechanics to not function naturally. The best results are now possible thanks to 3D modeling and computing technologies that can take readings and also map out what treatment will do to the affected areas.
These advanced corrective methods were able to come to light thanks to an increase in both the technologies surrounding biomechanics and also the knowledge of how they work naturally. For example, shoe orthotics are able to treat walking inabilities by realigning the posture deviations in patients caused by hip or back problems. Understanding foot biomechanics can help improve movement and eliminate pain, stopping further stress to the foot. Speak with your podiatrist if you have any of these problems.
Understanding Flat Feet

Flat feet occur when the medial longitudinal arch of the foot collapses, causing it to contact or nearly contact the ground. This condition can be present from birth or develop over time. Causes include aging, injury, obesity, or medical conditions that weaken the tendons and ligaments supporting the arch. Some individuals experience no discomfort, while others may have pain, swelling, or fatigue in the feet, ankles, or legs. A podiatrist can evaluate foot structure, identify the underlying cause, and recommend treatment custom orthotics, supportive footwear, and targeted exercises to improve alignment and relieve pain. If you have pain from flat feet, it is suggested that you consult a podiatrist who can offer you effective relief and management tips.
Flatfoot is a condition many people suffer from. If you have flat feet, contact one of our podiatrists from BayCity Associates in Podiatry . Our doctors will treat your foot and ankle needs.
What Are Flat Feet?
Flatfoot is a condition in which the arch of the foot is depressed and the sole of the foot is almost completely in contact with the ground. About 20-30% of the population generally has flat feet because their arches never formed during growth.
Conditions & Problems:
Having flat feet makes it difficult to run or walk because of the stress placed on the ankles.
Alignment – The general alignment of your legs can be disrupted, because the ankles move inward which can cause major discomfort.
Knees – If you have complications with your knees, flat feet can be a contributor to arthritis in that area.
Symptoms
- Pain around the heel or arch area
- Trouble standing on the tip toe
- Swelling around the inside of the ankle
- Flat look to one or both feet
- Having your shoes feel uneven when worn
Treatment
If you are experiencing pain and stress on the foot you may weaken the posterior tibial tendon, which runs around the inside of the ankle.

Flatfoot
Flatfoot is a foot disorder that is not as straightforward as many people believe. Various types of flatfoot exist, each with their own varying deformities and symptoms. The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot. Other signs of flatfoot include:
- “Toe drift,” or the pointing outward of the toes and the front part of the foot
- The tilting outward of the heel and the tilting inward of the ankle
- The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
- Hammertoes
- Bunions
One of the most common types of flatfoot is flexible flatfoot. This variation usually starts in childhood and progresses as one ages into adulthood. Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing. When not standing, the arch returns. Symptoms of flexible flatfoot include:
- Pain located in the heel, arch, ankle, or along the outside of the foot
- Overpronation, or an ankle that rolls in
- Shin splint, or pain along the shin bone
- General foot aches or fatigue
- Pain located in the lower back, hip, or knee
Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit. X-rays may be taken to define the severity and help determine the treatment option best for your condition. Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices. If nonsurgical methods prove ineffective, surgery may be considered. Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
Differences Between Corns and Calluses

Corns and calluses on the feet are caused by repeated pressure or friction, but they differ in appearance and symptoms. Corns are small, round, and often painful thickened skin areas that develop on toes or other bony prominences. They usually have a hard center surrounded by inflamed skin and can cause sharp pain when pressed. Calluses are larger, broader areas of thickened skin found on the soles or heels. They tend to be less painful but can feel rough or dry. Both conditions are often caused by wearing ill-fitting shoes, abnormal gait, or repeated rubbing. Visually, corns appear as hard, dense spots, while calluses look like rough patches. A podiatrist can diagnose these conditions through examination and identify underlying causes. Treatment may include orthotics, debridement, footwear advice, and addressing gait abnormalities. To prevent pain and further complications, it is suggested that you schedule an appointment with a podiatrist for effective relief and prevention tips.

Corns: What Are They? and How Do You Get Rid of Them?
Corns can be described as areas of the skin that have thickened to the point of becoming painful or irritating. They are often layers and layers of the skin that have become dry and rough, and are normally smaller than calluses.
Ways to Prevent Corns
There are many ways to get rid of painful corns such as wearing:
- Well-fitting socks
- Comfortable shoes that are not tight around your foot
- Shoes that offer support
Treating Corns
Treatment of corns involves removing the dead skin that has built up in the specific area of the foot. Consult with Our doctors to determine the best treatment option for your case of corns.
If you have any questions, please feel free to contact our offices located in Erie, PA and Meadville, PA . We offer the newest diagnostic and treatment technologies for all your foot care needs.
Corns: What Are They, and How Do You Get Rid of Them
Corns are thickened areas on the skin’s surface, to the point of being irritating and sometimes painful. Commonly found on the feet, corns are circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.
Corns are often confused with a callus, but there is a difference between them. Corns can be raised bumps that are painful to the touch. They consist of a rough, thick area of skin that may be dry or waxy. Corns tend to be surrounded by skin that is inflamed, and are usually much smaller than calluses.
Removing the dead skin that has built up is the key in treating corns. Salicylic acid medication is most common in accomplishing this. The acid works by dissolving keratin, which is the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in products such as wart removers. It comes in a variety of forms such as medicated pads, drops, or creams. However, people who are diabetic should not use salicylic acid, but should instead consult their doctor immediately.
According to the product directions, applying the medication directly onto the corn will treat it. The top layer of the corn will begin to turn white after use. When that occurs, the layers of skin can then be peeled away, making the corn smaller. Shaving off corns with razors or other pedicure equipment is never a good idea. This can lead to infection. If your corn gets infected, and is not treated immediately, a visit to the doctor will be necessary.
Another way to treat corns and help prevent their return is by using orthotic inserts, fitted by a podiatrist. Inserts fit right into your shoes and adjusts the way your foot fits into your shoes. This fixes the way you walk. This will lower your chances of getting corns, and eliminate current corns by reducing rubbing from friction.
Surgery is rarely used to treat corns, but does occur on occasion. Surgery actually deals with the underlying issue that causes corns. During surgery, the bone is shaved and any abnormalities are corrected, thus reducing the amount of friction that occurs during walking.
To prevent corns, the first step is reducing friction. Always wear shoes that fit well and don’t rub your feet. Pads can be purchased if you notice rubbing developing. These pads can be purchased over-the-counter, and can be simply placed on the irritated area. Wearing cushioned insoles in your shoes can always reduce the friction, and making sure to wear well-fitting shoes. This will ensure that your foot is not being squeezed awkwardly, and prevent corns from forming in the first place.
Common Reasons Your Feet Might Hurt

Foot pain can develop from a range of conditions that affect the bones, soft tissues, skin, or nerves. One frequent source of foot pain is plantar fasciitis. This is a repetitive stress condition resulting from inflammation of the thick band of tissue that runs along the bottom of the foot. Bunions are another cause, creating a visible bump near the big toe joint that can become painful and swollen. Tendon injuries, such as Achilles tendonitis, cause pain and stiffness near the heel, especially after activity. Nerve compression in the foot, such as tarsal tunnel syndrome, produces tingling, burning, or shooting sensations. Stress fractures, often related to repetitive impact or overuse, lead to localized pain and swelling that worsens with movement. A podiatrist can evaluate the structure of your foot, using imaging to confirm the cause of the pain. If you are experiencing any type of foot pain, it is suggested that you make an appointment with a podiatrist for a diagnosis and treatment options.

Foot pain can be extremely painful and debilitating. If you have a foot pain, consult with one of our podiatrists from BayCity Associates in Podiatry . Our doctors will assess your condition and provide you with quality foot and ankle treatment.
Causes
Foot pain is a very broad condition that could be caused by one or more ailments. The most common include:
- Bunions
- Hammertoes
- Plantar Fasciitis
- Bone Spurs
- Corns
- Tarsal Tunnel Syndrome
- Ingrown Toenails
- Arthritis (such as Gout, Rheumatoid, and Osteoarthritis)

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.
Retronychia and How It Differs from Ingrown Toenails

Retronychia is a lesser known nail condition that can sometimes be mistaken for an ingrown toenail. While ingrown toenails occur when the side of the nail curves into the skin, retronychia develops when a new nail plate grows underneath the old one instead of pushing it forward. This backward growth can cause thickening, discoloration, persistent pain, and swelling near the cuticle area rather than along the nail edge. It is more likely to appear after repeated trauma such as stubbing the toe or wearing tight shoes. Because retronychia may mimic some symptoms of ingrown toenails, it is easy to confuse the two conditions. However, their causes and treatments are different. If you are experiencing ongoing nail pain, swelling, or unusual nail changes, it is suggested that you seek the care of a podiatrist for a thorough evaluation and treatment plan.
Ingrown toenails can become painful if they are not treated properly. For more information about ingrown toenails, contact one of our podiatrists of BayCity Associates in Podiatry . Our doctors can provide the care you need to keep you pain-free and on your feet.
Ingrown Toenails
Ingrown toenails occur when a toenail grows sideways into the bed of the nail, causing pain, swelling, and possibly infection.
Causes
- Bacterial infections
- Improper nail cutting such as cutting it too short or not straight across
- Trauma to the toe, such as stubbing, which causes the nail to grow back irregularly
- Ill-fitting shoes that bunch the toes too close together
- Genetic predisposition
Prevention
Wearing proper fitting shoes and using proper cutting techniques will also help decrease your risk of developing ingrown toenails.
Treatment
Ingrown toenails are a very treatable foot condition. In minor cases, soaking the affected area in salt or antibacterial soaps will not only help with the ingrown nail itself, but also help prevent any infections from occurring. In more severe cases, surgery is an option. In either case, speaking to your podiatrist about this condition will help you get a better understanding of specific treatment options that are right for you.
