Choosing the Right Running Shoe for Your Foot Type

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.

Corns and Calluses

A corn is a lesion that forms in the skin of the foot, and it is typically circular in shape, small in size, and thick and rough in texture.  A corn generally occurs as a result of repeated pressure on the skin; one example of this is the rubbing of a shoe against the skin.  Corns differ from calluses in that their central cores are harder in texture.

A corn is a relatively common condition with a wide variety of treatment options.  If a corn becomes overly uncomfortable or painful, consult with your podiatrist; he can determine the best method of treatment that is appropriate for you.  Corns may return if the underlying cause of its development is not treated or removed.  Avoid removing corns at home, as improper removal may cause infection.

A callus, similar to a corn, is an area of skin that has become thickened due to repeated pressure and rubbing.  The rubbing causes the skin to create a layer of protective skin, which is the formed callus.  Calluses can differ in size between people, and they can also become painful.

Multiple treatments are available for calluses.  At-home treatment and removal should be avoided, as this can potentially lead to infection.  Your podiatrist can best determine the cause of your calluses and suggest the treatment most appropriate for you. 

Flat Feet

Flatfoot is a foot condition in which the arch of the foot has either partially or totally dropped or has never developed. While it is common in babies and small children, it can become a problem for them in adulthood if the arch never forms. For adults, the development of flat feet can be brought upon by injury, as a result of pregnancy due to increased elasticity, or obesity. Those who have health concerns such as rheumatoid arthritis or diabetes may also be at greater risk for developing the condition.

If you suspect that you have flat feet, it is best to consult your podiatrist. Your foot doctor will examine the suspected foot and observe how it looks while you sit and stand. He or she may take an X-ray to determine how serious the condition is. Some common signs of flatfoot include toe drift, in which the toes and front part of the foot point outward, a short Achilles tendon, and a heel that tilts outwardly while the ankle tilts inward.

Once flatfoot has been diagnosed, your podiatrist may suggest one of several treatment options. Flat feet can be rigid, in which the feet appear to have no arch even when the person is not standing; or flexible, in which the person appears to have an arch while not standing, but once standing the arch disappears. Those with flexible flatfoot may be told to reduce any activities that cause pain and to avoid extended periods of walking or standing. Another suggestion may be weight loss, as excessive weight may be placing pressure on the arches

In few cases, if the condition is severe and all other methods have been exhausted surgery may be required. This is normally avoided, however, due to a lengthy recovery time and high cost.

How to Treat Heel Spurs

Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.

There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.

Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.

The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment.  However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.

Plantar Fasciitis

Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is the thick band of tissue that connects the heel bone to the toes. When this band of connective tissue becomes inflamed, plantar fasciitis occurs. Fortunately, this condition is treatable.

There are several factors that may put you at a greater risk for developing plantar fasciitis. One of the biggest factors is age; plantar fasciitis is common in those between the ages of 40 to 60. People who have jobs that require them to be on their feet are also likely to develop plantar fasciitis. This includes factory workers, teachers, and others who spend a large portion of their day walking around on hard surfaces. Another risk factor is obesity because excess weight can result in extra stress being placed on the plantar fascia.

People with plantar fasciitis often experience a stabbing pain in the heel area. This pain is usually at its worst in the morning, but can also be triggered by periods of standing or sitting. Plantar fasciitis may make it hard to run and walk. It may also make the foot feel stiff and sensitive, which consequently makes walking barefoot difficult.

Treatment for plantar fasciitis depends on the severity of the specific case of the condition. Ice massage applications may be used to reduce pain and inflammation. Physical therapy is often used to treat plantar fasciitis, and this may include stretching exercises. Another treatment option is anti-inflammatory medication, such as ibuprofen.

If you suspect that you have plantar fasciitis, meet with your podiatrist immediately. If left untreated, symptoms may lead to tearing and overstretching of the plantar fascia. The solution is early detection and treatment. Be sure to speak with your podiatrist if you are experiencing heel pain.
