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.

Although ankle sprains may not be as serious as a broken ankle, they should be given immediate attention and care. An ankle sprain can lead to a significant amount of pain, as well as limited mobility. They are often characterized by the swelling and discoloration of the skin. This occurs when the ligaments are stretched beyond their limits.

The simple act of walking can sometimes cause a sprain, which makes ankle sprains a very common injury that can happen to anyone. They occur when the ankle twists in an awkward way or rolls over itself, causing a pop or snap in the tendons around the ankle. Some people are more at risk than others. These include athletes who continually push their bodies to the limits and also people who have previously suffered accidents to the feet, ankles, or lower legs.

Most of the time, an ankle sprain is not severe enough for hospital attention. There are many at-home treatment options available, including propping the leg up above your head to reduce blood flow and inflammation, applying ice packs to the affected area as needed, taking over-the-counter pain relievers and anti-inflammatory medication, using an ACE bandage to wrap and support the injured ankle, and most importantly, remaining off your feet until the ankle has fully healed.

Despite this, an ankle sprain can turn into a severe injury that might require hospitalization. If the ankle ligaments or muscles are damaged from a tear or rip, that is one sign that the sprain is severe enough for hospital attention and possibly for surgery. Even after the surgery, the recovery process can be long. You may need to have rehabilitation sessions administered by your podiatrist to get your ankle back to full health.

The severity of your sprain might become apparent if you are unable to stand or walk, consistent pain occurs over a prolonged period of time, swelling is much more severe than initially present, or if you start to experience tingling or numbness. These signs may indicate that your ankle sprain might actually be a broken ankle, an injury that requires immediate medical attention.

Although they are not completely avoidable, ankle sprains can be curbed with some preventative treatment measures. These include wearing appropriate-fitting shoes that not only provide a comfortable fit, but also ankle support. It is also recommended to stretch before doing any kind of physical activity, as this will help lower your body’s chance for an injury.

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.

Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in children’s feet while they’re growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14.

Sever's disease occurs when the child’s growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, is injured or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel. This forces the child to bear weight on their toes while walking. When a toe gait develops, the child must change the way they walk to avoid placing weight on the painful heel. If this is not properly addressed, this can lead to further developmental problems.

The most common symptom of Sever's disease is acute pain felt in the heel when a child engages in physical activity such as walking, jumping or running. Children who are active athletes are among the group most susceptible to experiencing Sever's disease. This is due to the extreme stress and tension placed on their growing feet. The rolling movement of the foot during walking or running and obesity are both additional conditions linked to causing Sever's disease.

The first step in treating Sever's disease is to rest the foot and leg and avoid physical activity. Over the counter pain-relieving and anti-inflammatory medications can be helpful for reducing the amount of heel pain. A child with Sever's disease should also wear shoes that properly support the heel and the arch of the foot. Consider purchasing orthotic shoe inserts which can help support the heel and foot while it is healing. Most patients with Sever's disease symptoms report an eventual elimination of heel pain after wearing orthotic insoles that support the affected heel.

Sever's disease may affect either one heel or both. It is important for a child experiencing heel pain to be examined by a foot doctor who can apply the squeeze test. The squeeze test compresses both sides of the heel in order to determine if there is intense pain. Discourage any child diagnosed with Sever's disease from going barefoot as this can intensify the problem. Apply ice packs to the affected painful heel two or three times a day for pain relief.

Exercises that help stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling has also proven to be very effective at treating Sever's disease. When foot curling, the foot is pointed away from the body, then curled toward the body to help stretch the muscles. The curling exercise should be done in sets of 10 or 20 repetitions and repeated several times throughout the day.

Treatment methods can continue for at least 2 weeks and as long as 2 months before the heel pain completely disappears. A child can continue doing daily stretching exercises for the legs and feet to prevent Sever’s disease from returning.
