Choosing the Right Running Shoe for Your Foot Type
While running seems like a simple activity, it is actually a complicated movement that puts a lot of stress on the joints, bones and ligaments of the body. Consequently, choosing the right shoe is an important step in increasing performance and decreasing injury risk. You should select running shoes based on your foot type. While other considerations are important, such as trail versus road shoes, your foot type dictates the amount of cushioning, stability and motion control you need. The best way to determine your foot type is to visit a local specialty running shop. Professionals there can measure your arch type, stride and gait and summarize your shoe needs for future reference.
Running shoe design is based on the idea of pronation. Pronation is the natural rolling of your ankle from outside to inside during foot strike. In other words, proper running mechanics involve striking the ground on the outside of your heel and rolling toward your big toe before pushing off again. Pronation is a good thing: it helps your lower extremities absorb shock and store energy. Neutral runners who pronate correctly do not depend on their shoes to correct their form. Neutral runners can select from a large variety of shoes, even minimal or barefoot models. However, runners with problematic foot arches or incorrect form may pronate too much or too little and require specific qualities from their running shoes.
Overpronators run with excessive ankle rolling. Even when standing, severe overpronators exhibit ankles that angle inward. They also tend to have flat feet or bowed legs. Overpronation can cause a plethora of injuries, especially in the knees, ankles and Achilles tendons. If you overpronate, you should select a shoe with extra stability and motion-control. Motion-control shoes are firm and straight; they do not curve at the tip. The lack of flexibility along the midsole prevents the foot from rolling too far inward during your foot strike.
Underpronation, also called supination, is less common than overpronation. Unlike overpronators, underpronators have inflexible feet and high arches. When they land, their feet are unable to roll inward. While this places less rotational stress on the ankles and knees, it prevents any kind of shock absorptions. This additional force can result in fractures, ligament tears and muscle strains as the legs compensate for the impact. Underpronators require shoes with increased cushioning and flexibility. If you underpronate, stability or motion-control shoes may compound the problem by further preventing pronation.
Rheumatoid Arthritis in the Feet
Although rheumatoid arthritis actually attacks multiple bones and joints throughout the entire body, ninety percent of people who actually develop this condition usually do so in the foot or ankle area. Those who develop this kind of arthritis in the feet usually develop symptoms around the toes and forefeet first, before anywhere else. Rheumatoid arthritis appears to have a genetic component. If it runs in the family, then you will be more likely to develop it as well.
Rheumatoid arthritis is an autoimmune disorder in which the body’s own immune system attacks the lining of the membranes surrounding the joints. This causes inflammation of the membrane lining, and the gradual destruction of the joint’s cartilage and even bone.
Some of the most common symptoms that are associated with RA include pain and swelling of the feet. Stiffness in the feet is also another common symptom that people experience. Those who have RA in the feet usually feel the pain in the ball or sole of their feet. This can get to be very painful at times. A person's joints can even shift and become deformed after a period of time.
In order to properly diagnose RA in the feet it is usually necessary for a doctor or podiatrist to evaluate the area. Your doctor will also question you about your medical history, occupation, etc., to determine whether anything in your lifestyle may have triggered the condition. There are a number of tests that may be performed to help diagnose RA such as a rheumatoid factor test, although there is no one single test that will tell you for sure if you have RA. There are different X-rays that can be taken as well to determine if a person has RA in their feet.
There is a range of treatment options for rheumatoid arthritis. Treatment of RA is usually a lifelong process that includes a variety of methods of treatment and therapy. Your doctor can prescribe special shoes that should help with arch support as well as heel support. A physical therapist can help those with this condition learn exercises which will keep their joints flexible. Surgery may be needed to correct some of the issues with the feet, such as bunions, and hammertoes. Fusion is usually the most successful surgical option for rheumatoid arthritis. However, people need to keep in mind that there are some risks associated with these surgeries.
Broken Foot Causes, Symptoms, and Treatment
A broken foot is when one of the bones located in the foot fractures, or breaks. About 10% of broken bones occur in the foot.
Bones typically break when an object crushes, bends, or stretches the bone. In the foot, the location of the broken bone is usually indicative of how the break occurred. Toes usually break when something hard and solid is kicked with great force. Broken Heels are usually a result of falling from a great height and landing on the feet. Other broken bones in the feet can occur because of a twisted or sprained ankle. Most of the time, a broken foot results from a sudden accident or injury. Sometimes small cracks can form over time in the bones of the feet from repeated stress. These cracks are called stress fractures and usually only occur in athletes that put a lot of pressure on their feet, like runners, dancers, and gymnasts.
Symptoms of a broken foot typically include pain, swelling, bruising, and redness. Occasionally the pain of a broken foot may be so severe that walking is not an option. However, this depends on the location of the broken bone within the foot. Broken toes are usually less painful than broken heels or other bones within the foot. A foot that is blue, numb, cold, misshapen, cut or deformed can occur in more serious cases of broken feet. Those who are experiencing any of these symptoms, or suspect that they have a broken foot, should seek medical attention in a center where x-rays can be performed.
Prior to seeking the attention of a doctor, several steps can be taken at home in order to reduce pain and swelling. Stabilization and elevation of the broken foot should be the number one priority. It is important not to move the foot, so any type of homemade splint will work well. However, any splint that causes the foot to become more painful, or cut off blood circulation should be removed. Ice can also decrease swelling and alleviate some of the pain that a broken foot can cause.
In a medical center, treatment for a broken bone will differ depending on which bone in the foot is fractured and depending on what caused the break. Some broken feet will require the patient to use crutches, while others will require splits or casts. More severe cases may require surgery on the foot to repair the broken bone or bones.
What to Know About Achilles Tendon Injuries
The Achilles tendon is the strongest tendon in the human body, connecting the heel to the lower leg and calf muscles. This tendon helps to aid the process that involves movement in the legs, such as walking and running. Since this tendon is very important, if there are any injuries to the Achilles tendon they need to be addressed by a physician immediately.
Achilles tendon injuries risk Achilles tendinitis. Often diagnosed through MRI, Achilles tendinitis involves inflammation, an increased blood flow to the tendon, tendon thickening, pain that ranges from dull to severe and slowed movement.
Achilles tendon ruptures are caused by the tendon snapping or ripping, with more immediate, and painful, symptoms. Depending on the injury’s severity, treatment and recovery time for Achilles tendon ruptures often vary, which may take up to a year. Fortunately there are both operative and non-operative methods available in terms of treatment.
Although no injury is completely preventable, there are ways to minimize the chances of incurring an injury. Be sure to stretch out the tendon before and after physical activity as it can stimulate the tissue. Exercises that include squats, calf raises, lunges, leg presses, leg curls and leg extensions are all good ways to help strengthen the tendon.
Individuals who may overexert themselves during physical activity incur a higher risk for these injuries. This is especially true for athletes. Try to be on a cushioned surface when exercising, such as a mat, as heel pressure can be relieved this way. Occasion appropriate footwear can also serve to minimize the risk of tendon-related injuries. And of course, a healthy diet increases tendon, and bodily, health while decreasing obesity associated risks.
Visit a podiatrist if you think you have an injury in the Achilles region. Failure to address these injuries can cause further damage and complications that could even render you immobile.
