Running may seem like a simple to do. However, running is actually a complex movement that puts stress on the ligaments, bones, and joints of the body.  Selecting the correct running shoe is important for increasing performance and avoiding risk of injury.  Running shoes should be selected based on your foot type.  Considerations such as trail versus road shoes are important. Your foot type dictates the degree of cushioning, stability and motion control you require.  The most accurate way to learn your foot type is to visit a local shop that specializes in running shoes.  Professionals can measure your arch type, stride and gait and help you with your shoe needs.

The design of running shoes is created around the idea of pronation.  Pronation is the natural rolling movement of your ankle from the outside to inside when your foot strikes the ground.  If you run properly you strike the ground on the outside of your heel and roll in the direction of your big toe before pushing off once more.  Pronation is beneficial because it assists the lower half of your body in absorbing shock and storing energy.  Those considered neutral runners pronate correctly and do not need running shoes that help correct their form.  Neutral runners can choose from a wide variety of shoes, including barefoot or minimal types.  However, those who have arch problems or who adopt an incorrect form while running may experience too much or too little pronation. They may require running shoes that offer additional support.

Those who overpronate experience an over-abundance of ankle rolling.  Even while standing, those who severely overpronate display ankles that are angled inward.  It is not uncommon for them to have flat feet or curved legs.  The tendency to overpronate may cause many injuries.  Areas that tend to become injured are the knees, ankles, and Achilles tendon.  If you find that you have a tendency to overpronate, you should look at shoes that provide extra stability and motion-control.  Motion-control shoes are straight and firm. Shoes of this type do not curve at the tip.  The restricted flexibility along the middle of the shoe prohibits the foot from rolling too far inward as your foot strikes the ground.

A less common problem is underpronation.  Underpronation, also called supination, is when the feet are unable to roll inward during landing.  Those who underpronate have feet that lack flexibility and high arches.  This prevents any kind of shock absorption, even though it does place less rotational stress on ankles and knees.  This added force can cause fractures, ligament tears, and muscle strains because the legs are trying to compensate for the impact.  Those who underpronate need shoes with more cushioning and flexibility.  If you have a tendency to underpronate, selecting stability or motion-control shoes may cause you more problems by continuing to prevent pronation.

Flatfoot is classified as having the entire sole of the foot in contact or near contact to the ground while standing. The disorder is also known as fallen arches, because those affected have no arch in their feet. Flexible flatfoot and rigid flatfoot are the two types of flatfoot.

A person has flexible flatfoot if when sitting or standing on their toes, they have an arch that disappears when they stand with the entire foot on the ground. Flexible flatfoot may also be called “pediatric flatfoot” because the condition first appears in childhood. It is common among infants because the arch does not develop until the age of 5 or 6 years. Rigid flatfoot is not as common in children as it is with adults. This type of flatfoot is developed due to the weakening of tibialis posterior muscle tendon, a major supporting structure of the foot arch. Development of this deformity is progressive and shows early signs of pain and swelling that begins at the inside arch of the foot and moves to the outside of the foot below the ankle. More severe cases can possibly lead to arthritis of the foot and ankle joints.

Although most cases of flatfoot involve people born with the condition, some less common causes are obesity, diabetes, pregnancy, and osteoporosis. In some cases, flatfoot may come with no symptoms at all and does not require any type of treatment. With other cases though, symptoms may include pain in the shin, knee, hips and lower back. If a person with flatfeet experiences such symptoms, a health care provider may suggest using orthotic devices or arch supports, which may reduce the pain. Wearing supportive shoes can also prove more comfortable with flatfeet and staying away from shoes with little support such as sandals. Other methods to relieve pain also include stretching the Achilles tendon properly and using proper form when doing any physical activity. In addition, losing weight can reduce the stress on your feet and reduce the pain.

Ankles are joints that connect bones in the feet with bones in the lower leg. They are comprised of bones, ligaments, muscles, tendons, blood vessels, and nerves. The ankle joint allows the foot to move side-to-side, as well as up-and-down.

Ankle pain can be caused by a variety of conditions, but is most commonly due to soft tissue injuries such as ankle sprains and strains. 

An ankle sprain occurs when one or more of the strong ligaments that support and stabilize the ankle become overly stretched or even torn if the ankle rolls, turns, or twists awkwardly. Depending on the grade of sprain (mild-moderate-severe), there will be varying degrees of pain, swelling, and restricted range of motion, along with tenderness, bruising, and ankle instability. There may even be an audible popping noise at the moment of injury.

Ankle strains can sometimes produce similar symptoms of pain, swelling, and loss of motion, however, they are due to overly stretched muscles and tendons—not ligaments. Ankle strains may also cause muscle cramps in the feet, calves and shins.

Ankle fractures are another common source of ankle pain and occur one or more of the three bones in the ankle become fractured (broken). These breaks can be stress fractures (due to repetitive stress) or traumatic fractures (due to an acute injury). Depending on where and how severe the fracture is, symptoms can include pain and swelling that can sometimes spread up to the knee, bruising or discoloration, and an inability to bear weight. A visible deformity or exposed bone may occur in severe fractures.

Various forms of arthritis may also cause ankle pain. Rheumatoid arthritis (RA) causes the immune system to attack healthy joints, like the ankle joint, by mistake, causing stiffness and swelling in both ankles. Osteoarthritis occurs when cartilage covering the ends of bones wears down, causing the bones to rub against each other. This results in pain, stiffness, and reduced range of motion in the ankle. Gout is a form of arthritis where excess amounts of uric acid in the bloodstream crystallize and build up on joints, causing severe pain and swelling. Reactive arthritis causes joint pain and swelling in the ankle in response to an infection in another part of the body.

Other forms of ankle pain include bursitis (an inflammation of a cushioning bursa sac between tendons and bone), scleroderma (a thickening of connective tissues), chronic ankle instability (caused by improperly healed ankle sprains), Achilles tendon injuries, flat feet, or an infection in the ankle.

While not a serious issue, toenail fungus, or onychomycosis, can be an embarrassing and uncomfortable condition to experience. Toenail fungus is often caused from public areas that harbor fungi and improper cleaning/drying of the foot. Once infected, the fungus grows deeper into the nail and can be very hard to get rid of.

There are different types of fungus that cause toenail fungus. Dermatophytes, yeasts, and molds are the most frequent forms of fungus to infect the toenail. Dermatophytes are the most common among the three. Symptoms associated with fungal nails include the discoloration of the toenail, brittleness, and in some circumstances, a smell. Pain is rarely a symptom caused by toenail fungus.

Diagnosis of fungal nails is generally a rather quick process. However podiatrists will make sure that the cause is not another condition such as lichen planus, psoriasis, onychogryphosis, or nail damage. Podiatrists will make use of fungal cultures and microscopy to verify that it is fungus.

While over-the-counter ointments are readily available, most are ineffective. This is due to the fact that the nail is very protective and that the fungus slips in between the nail plate and bed. Podiatrists can offer oral medication which currently provides the best results.

Ultimately, prevention is the best line of defense against toenail fungus. Avoid unsanitary public showers. If you do use a public shower, use shower shoes to provide your foot with protection. Once you are finished showering, make sure to thoroughly dry your feet. Fungi thrive in warm, dark, and moist places like sweaty, warm feet that are left dark in shoes all day.
