The Architecture of the Foot

The foot is a marvel of anatomical design, essential for effective heel-to-toe walking. The heel's support comes from the calcaneus bone, which absorbs impact during the initial heel strike. The Achilles tendon, connecting the calf muscles to the heel, plays a vital role in lifting the heel and propelling the body forward. The fibula and tibia, the major bones of the lower leg, provide structural stability and support to the ankle joint. The talus, situated between the tibia and calcaneus, facilitates smooth movement of the foot. As the foot rolls forward, the metatarsals and phalanges work together to push off the ground. This intricate coordination of bones, tendons, muscles, and ligaments ensures efficient movement and balance throughout each step. A podiatrist is medically qualified to treat foot and ankle conditions. If you have injured your foot or have chronic foot pain, it is suggested that you contact a podiatrist who can offer safe and effective treatment solutions.

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.
How to Prevent Running Injuries
Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.
One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.
Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.
Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.
What Is Hallux Rigidus?
Hallux rigidus is a form of degenerative arthritis affecting the joint at the base of the big toe. This condition leads to stiffness, pain, and limited movement in the toe, often making walking or other activities difficult. The primary cause of hallux rigidus is wear and tear of the cartilage in the joint, which can result from repetitive use, injury, or genetic predisposition. People at risk for hallux rigidus include those with a family history of the condition, athletes, or individuals whose activities put repeated stress on the big toe joint, such as dancers or certain laborers. Treatment options vary depending on the severity and can include non-surgical approaches like targeted stretching exercises, anti-inflammatory medications, and custom orthotics to reduce pressure on the toe. In more severe cases, surgery may be necessary to alleviate pain and restore mobility. If you have big toe pain, it is suggested that you schedule an appointment with a podiatrist for a proper diagnosis and treatment.
Toe pain can disrupt your daily activities. If you have any concerns, contact Kimberly Woodard, DPM of Pinnacle Foot and Ankle Centers, LLC . Our doctor can provide the care you need to keep you pain-free and on your feet.
What Causes Toe Pain?
Most severe toe pain is caused due to a sports injury, trauma from dropping something heavy on the toe, or bumping into something rigid. Other problems can develop over time for various reasons.
Toe pain can be caused by one or more ailments. The most common include:
- Trauma
- Sports injury
- Wearing shoes that are too tight
- Arthritis
- Gout
- Corns and calluses
- Hammertoe
- Bunions
- Blisters
- Ingrown toenails
- Sprains
- Fractures (broken bones)
- Dislocations
When to See a Podiatrist
- Severe pain
- Persistent pain that lasts more than a week
- Signs of infection
- Continued swelling
- Pain that prevents walking
Diagnosis
In many cases the cause of toe pain is obvious, but in others, a podiatrist may want to use more advanced methods to determine the problem. These can range from simple visual inspections and sensation tests to X-rays and MRI scans. Prior medical history, family medical history, and any recent physical traumatic events will all be taken into consideration for a proper diagnosis.
Treatment
Treatments for toe pain and injuries vary and may include shoe inserts, padding, taping, medicines, injections, and in some cases, surgery. If you believe that you have broken a toe, please see a podiatrist as soon as possible.

Toe Pain
Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures.
Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.
Treatment for Fungal Toenail Infections
Fungal toenail infections, or onychomycosis, are common conditions where fungi invade the nails, leading to discoloration, thickening, and crumbling of the nail edges. These infections often cause the nails to turn yellow, brown, or white and can lead to discomfort or a foul odor. Fungal toenail infections occur due to exposure to fungi in warm, moist environments such as public showers, swimming pools, or locker rooms. They can also result from minor nail injuries, wearing tight-fitting shoes, or poor foot hygiene. Individuals with weakened immune systems, diabetes, or circulatory issues are more susceptible to these infections. Athletes and those who frequently wear closed-toe shoes are also at higher risk. Treatment options can include antifungal medications, which can be topical or oral. In severe cases, laser therapy or surgical removal of the affected nail may be needed. Maintaining good foot hygiene, keeping nails trimmed and dry, and wearing breathable footwear can help prevent infections. If you have toenail fungus, it is suggested that you contact a podiatrist for a proper diagnosis and care.
If left untreated, toenail fungus may spread to other toenails, skin, or even fingernails. If you suspect you have toenail fungus it is important to seek treatment right away. For more information about treatment, contact Kimberly Woodard, DPM of Pinnacle Foot and Ankle Centers, LLC . Our doctor can provide the care you need to keep you pain-free and on your feet.
Symptoms
- Warped or oddly shaped nails
- Yellowish nails
- Loose/separated nail
- Buildup of bits and pieces of nail fragments under the nail
- Brittle, broken, thickened nail
Treatment
If self-care strategies and over-the-counter medications does not help your fungus, your podiatrist may give you a prescription drug instead. Even if you find relief from your toenail fungus symptoms, you may experience a repeat infection in the future.
Prevention
In order to prevent getting toenail fungus in the future, you should always make sure to wash your feet with soap and water. After washing, it is important to dry your feet thoroughly especially in between the toes. When trimming your toenails, be sure to trim straight across instead of in a rounded shape. It is crucial not to cover up discolored nails with nail polish because that will prevent your nail from being able to “breathe”.
In some cases, surgical procedure may be needed to remove the toenail fungus. Consult with your podiatrist about the best treatment options for your case of toenail fungus.

Toenail Fungus
Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.
The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.
Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.
Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
A Visual Analysis of a Bunion

A bunion is characterized by a protrusion at the base of the big toe. It manifests as a bony bump caused by the misalignment of the joint, often leading to the big toe pushing against the adjacent toes. Bunions vary in severity, classified into degrees based on visual cues. Mild cases exhibit slight deviations of the big toe, with minimal outward protrusion. Moderate bunions display more pronounced misalignment and a visible bump. Severe bunions are marked by significant joint displacement, causing the big toe to angle drastically toward the other toes. The visual features include redness, swelling, and sometimes pain surrounding the affected area, affecting mobility and comfort. If you have developed a bunion, it is suggested that you contact a podiatrist who can offer you effective relief and treatment remedies.
If you are suffering from bunion pain, contact Kimberly Woodard, DPM of Pinnacle Foot and Ankle Centers, LLC . Our doctor can provide the care you need to keep you pain-free and on your feet.
What Is a Bunion?
Bunions are painful bony bumps that usually develop on the inside of the foot at the joint of the big toe. As the deformity increases over time, it may become painful to walk and wear shoes. Women are more likely to exacerbate existing bunions since they often wear tight, narrow shoes that shift their toes together. Bunion pain can be relieved by wearing wider shoes with enough room for the toes.
Causes
- Genetics – some people inherit feet that are more prone to bunion development
- Inflammatory Conditions - rheumatoid arthritis and polio may cause bunion development
Symptoms
- Redness and inflammation
- Pain and tenderness
- Callus or corns on the bump
- Restricted motion in the big toe
In order to diagnose your bunion, your podiatrist may ask about your medical history, symptoms, and general health. Your doctor might also order an x-ray to take a closer look at your feet. Nonsurgical treatment options include orthotics, padding, icing, changes in footwear, and medication. If nonsurgical treatments don’t alleviate your bunion pain, surgery may be necessary.

Bunions
A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.
Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.
A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.
Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.
For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.
Managing Your Flat Feet

Flat feet, or fallen arches, occur when the arches of the feet collapse, causing the entire sole to touch the ground. While some individuals have flat feet from childhood, others may develop them later in life. A primary cause of flat feet is genetics. If your parents or grandparents had flat feet, there is a higher likelihood of inheriting the condition. Additionally, injuries or stress to the feet's tendons and ligaments or standing for long periods of time can lead to flat feet. Symptoms may include foot pain, swelling, and difficulty with movement. In severe cases, surgical intervention may be necessary to reconstruct the arches. To accurately diagnose the extent of flat feet and determine what the most effective treatment plan is, it is important to consult a podiatrist. They can provide expert assessment, recommend appropriate interventions like custom orthotics, and ensure ongoing management to alleviate symptoms and improve foot function. It is suggested that you schedule an appointment with a podiatrist for personalized care and relief from flat feet.
Flatfoot is a condition many people suffer from. If you have flat feet, contact Kimberly Woodard, DPM from Pinnacle Foot and Ankle Centers, LLC . Our doctor 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.
