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.
About Plantar Warts
The term plantar means relating to the foot, which is why plantar warts are only found on the feet. Plantar warts are caused by the human papillomavirus (HPV) getting into open wounds on the feet. These warts are recognizable by a hard bump on the foot. They are mostly found heels or on the balls of the feet. Plantar warts are basically harmless, and may be ignored unless they cause pain or embarrassment.
If you have a plantar wart you may notice some pain when standing, or just some tenderness on the sole of your foot. You will be able to see a fleshy wart, unless it has grown into the foot behind a callus. Since plantar warts are not cancerous and not dangerous, a podiatrist only needs to be seen if there is excess pain, the warts come back often or persist for some time, or if it affects walking. It is extremely important that people suffering from compromised immune systems or diabetes seek out a physician’s care immediately upon finding a plantar wart on their foot.
Doctors can usually easily diagnose plantar warts. The doctor will scrape off a tiny bit of the rough skin to make tiny blood clots visible that make up the inside of these warts. If the doctor is unsure of a diagnosis they may do a biopsy to be certain. Though plantar warts don't often call for treatment, there are many options for combating them if need be. They can be frozen using liquid nitrogen, removed using an electric tool or burned using laser treatment. For a less invasive treatment a topical cream can be used which is available only through a prescription. Over the counter wart medications may help, given enough time and patience.
If you prefer to use home remedies an apple cider vinegar soak is believed to help remove the wart. This treatment takes time. Soak your infected foot in the vinegar for 20 minutes before using a pumice stone to remove any loose skin from the wart. Keep the wart covered for protection in between daily treatments.
The best way to avoid contracting plantar warts is to avoid walking barefoot in public areas. This includes wearing shoes in public showers also. It is also important to avoid direct contact with warts, as they can be contagious. This means not touching your own warts, as well as those on others.
How Obesity Affects Your Feet
Maybe you have gained a few extra pounds over the past couple of years. It comes on slowly and you are not always aware of it until your feet start hurting at the end of the day. After all, they carry the weight of your whole body. Experiencing foot pain and swelling is one of the biggest side effects of being overweight.
Many problems that occur in the feet are directly related to carrying even a small amount of extra weight. If you are overweight, the body may try to compensate by changing the way it moves. You may lean forward a bit and put extra weight on the wrong part of the foot. Your feet were designed to carry a normal amount of body weight and any extra will put undue stress on them.
Many people who are overweight as adults develop type 2 diabetes and it is often the cause of leg and foot pain. This is very serious and often older people who do not control their condition may lose all feeling in their legs and feet. It is also possible to develop small sores on the feet, and when you have diabetes, these do not always heal properly which can lead to serious infection.
The extra pressure and stress placed on muscles, joints, and tendons in the feet by extra body weight can also trigger plantar fasciitis. Plantar fasciitis is an inflammation of the tissue along the bottom of the foot, and causes pain and stiffness when walking and climbing stairs. Pain caused by plantar fasciitis can be relieved by foot stretches and orthotics inserted into the shoe.
Foot problems triggered by excess body weight may be treated by special attention to footwear. Shoes that properly support the foot – especially the arch and ankle – and allow for good circulation are very important. A podiatrist can help you decide what kind of shoe is best for your feet. Orthotics – special inserts that can be inserted into shoes – can absorb shock, support the arches, and keep the feet properly aligned. These can be found in shoe stores or may be fitted by a podiatrist.
It may also be time to consider taking off a few pounds to prevent diabetes and other life threatening diseases. Your feet will certainly thank you for it and you will feel better in a short amount of time. A water aerobics class at a local gym is a way to get needed exercise without putting any stress on the feet or ankles. Yoga is also an activity that is beneficial both to your feet and your entire body. Don't risk losing your freedom by ignoring foot pain. If you take care of your feet, you can keep your feet and your entire body feeling great.
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 structure and focuses on the movement of the ankle, the foot and the forces that interact with them.
At some time in our lives we will all experience foot problems, regardless of our lifestyle or age, and we all take our mobility for granted until we are in pain. Twists or turns can cause problems and apply stress to the feet, and that pain will spread from the foot structure to the surrounding tissues. The pain will concentrate in the foot and ankle, but may eventually spread up into the knees, hips and back.
The history of biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded. Afterwards, during the first century AD, corns on feet were recorded as specifically growing on feet and toes. 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 of conditions could be implemented to gain strength and coordination to the area. His basic principles of thermoplastic foot orthotics are still in use throughout the industry today.
Modern technology improvements are based on past theories and therapeutic processes providing a better understanding of podiatry concepts for biomechanics. Computers provide accurate determinations about the forces, movements and patterns of the foot and lower legs with the most important information captured. Today’s knowledge of detailed measurement of external and internal forces in the foot is critical to the individual’s treatment. Like most health industries, precise determinations assist the practitioner in diagnosing and prescribing the best treatment for health improving results.
Advances in materials and more awareness of biomechanics have developed enhanced corrective methods, offering further options for foot-related injuries. Shoe orthotics options have expanded to treat walking inability, helping to realign the posture deviations caused by hip or back health occurrences. Attention to posture and foot mechanics uses individual insoles to position the foot, aligning the ankle and leg. The corrected positioning comforts the pressure and helps to ease the pain. Understanding foot biomechanics can help improve and eliminate pain, stopping further stress to the foot. However, these results can only happen if one seeks a podiatrist who specializes in biomechanics.
