Platelet rich plasma, or PRP, is blood taken from a patient and spun in a centrifuge, concentrating the amount of platelets and growth factors. This plasma, containing a very high concentration of platelets, is re-injected into the site of injury or damage, inducing the body to repair damage to muscle, tendons, ligaments, and soft tissue. Although the body does this naturally when an injury occurs, the PRP helps speed the healing process.
Many injuries to the foot, especially those affecting tendons, do not heal well because poor blood supply to the area prevents healing platelets and growth factors carried by the blood from getting to the injury site. Platelet rich plasma (PRP) injections can help fix this problem and speed recovery.
This is the first regenerative treatment ever for damaged muscles, tendons, and ligaments. It avoids the need for surgery, and as it requires only the insertion of a needle, is minimally invasive. The injection of PRP is done with the use of ultrasound to ensure the proper placement of the platelets.
Once the first injection is received, the patient will return to the doctor's approximately 2 to 3 weeks later to be checked on how well the treatment is moving along. As with most treatments, each patient's response is different. Based on a patient's condition, the doctor will make the decision about how many more injections will be needed. Acute and chronic injuries will typically require more injections than mild ones.
Common injuries of the feet such as ankle sprains, Achilles tendonitis, and plantar fasciitis, as well as acute and chronic tendon and joint diseases like arthritis, can all be treated with PRP injections. For many, this therapy has lead to greatly reduced pain and increased function of the foot. Combining exercise or physical therapy with the PRP injections will help increase the success of the treatment.
This treatment, being minimally invasive, means that surgery can be avoided, in many cases, and recovery time cut down. Other benefits of PRP injections are a decrease in scar tissue and fibrosis to the damaged area, as well as increased range of motion, flexibility, and strength. The risks from using PRP injections as a treatment is very low. As the patient is injected with his own blood, there is no risk of rejection or of getting a disease from using another person's blood. As with any injection into the body, there is a risk of infection, but this is very rare. Research is showing that PRP may have an anti-bacterial property that would further decrease the risk of infection.
In most cases, foot surgery is often chosen as the last available option for conditions that have otherwise been unsuccessfully treated. Surgery may be necessary for several reasons, including the removal of foot deformities (e.g. bone spurs or bunions), arthritis problems, reconstruction due to injury, and congenital malformations (e.g. club foot or flat feet). Regardless of one’s age, foot surgery may be the only successful option for treatment for certain conditions.
The type of surgery one undergoes depends on the type of foot condition the patient has. For the removal of a bunion growth, a bunionectomy is necessary. If the bones in the feet need to be realigned or fused together, a surgical fusion of the foot is needed. For pain or nerve issues, a patient may require surgery in which the tissues surrounding the painful nerve are removed. Initially, less invasive treatments are generally attempted; surgery is often the last measure taken if other treatments are unsuccessful.
While in many cases surgery is often deemed as the final resort, choosing surgery comes with certain benefits. The associated pain experienced in relation to the particular condition is often relieved with surgery, allowing patients to quickly resume daily activities. The greatest benefit, however, is that surgery generally eliminates the problem immediately.
Podiatry history has shown that foot treatments continue to evolve over time. In the field of foot surgery, endoscopic surgery is just one of the many advanced forms of surgery. As technology vastly improves so too will the various techniques in foot surgery, which already require smaller and smaller incisions with the use of better and more efficient tools. Thanks to such innovations, surgery is no longer as invasive as it was in the past, allowing for faster and easier recoveries.
There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.
In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.
Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.
There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.
Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.
All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.
Our feet are important in our everyday lives. The problem is that we tend to neglect them. When this becomes a habit, it can cause significant trouble. Ignoring foot problems can mean pain, limited mobility, and expensive doctor's visits. On the other hand, if feet are cared for and looked after regularly, they will perform without pain or complication.
Routine hygiene is the most basic way to care for the feet. Wash and dry them thoroughly daily. Remember to get between the toes and keep the toenails trimmed and short. If the feet feel dry or there are signs of dryness or cracking, use a moisturizer designed for the feet.
When using moisturizer on the feet, try to avoid applying between the toes. If cream or lotion sits too long, they can cause fungal and bacterial growth. When moisturizer is used between the toes, it can also cause the skin to soften too much.
Shoes are also an important aspect of foot care. When one is picking out shoes, make sure they are the correct size. Shoes need to be snug, but not too tight. On the other hand, if shoes are too loose they can cause foot problems as well. It is highly recommended that shopping for new shoes be done later in the day. The reason for this is that the feet will have settled and swelled to their full size by then. To keep your feet at their most healthy, avoid wearing high heels or flip flops too often. Instead, choose shoes that are good for your feet. Good shoes pad the soles of your feet and support the arches and ankles.
Socks should also be worn daily with closed-toe shoes. They may feel hot during the summer months, but they absorb sweat and moisture off the feet. Without socks, the build-up of sweat in a closed-toe shoe can cause fungal problems and athlete's foot.
The best thing to remember in every day foot care is that shoes do make a difference. If you spend a lot of time on your feet, make sure that your shoes show no signs of wear. Shoes should offer ample support for the arches and the overall foot. Additionally, try to make foot cleaning and maintenance a daily habit. If you keep these things in mind, your feet will stay healthy and safe.
Whether your feet are over-worked or under-worked, chances are they could benefit from some special attention. Even those who exercise regularly probably do not spend any time strengthening their feet. This can be just as rewarding as strengthening the rest of the body, since the health of your feet affects the health of the rest of the body as well, especially the ankles, legs, and spine.
For those who might not have any idea on how a foot-specific exercise might be conducted, there are several workouts that are fairly easy to perform in the comfort of ones’ home. One of the easiest is the toe rise, also known as the tip-toe. This exercise involves standing on the tip-toes for a count of 15 then resting the feet on the ground. This process should be repeated a minimum of three times a day in order to strengthen the feet.
Toe pick-ups strengthen the feet by working them in a very different way. In this exercise, small items are picked up using the toes in order to strengthen the muscles on the upper part of the feet. Once again three sets should be performed, with the item in question being held for 15 seconds then dropped. Items that may be picked up using the feet include marbles and even stationery, which works wonders for the toes and the surrounding muscles.
Yet another simple workout is the ankle pump. This can be done either upwards or downwards, but for the workout to be most effective both can be incorporated into the routine. As the term suggests, this involves lifting the foot off the floor and flexing the toes either towards the shin or towards the ground. This movement puts the feet and ankles through a large range of motion which works the muscles.
Last but not least, feet should be stretched so that the muscles can relax and recuperate. This can be done by placing both feet off of the floor and bracing oneself against the wall at a 45 degree angle. This ensures that the feet and ankles are adequately stretched once the workout is complete.
In short, giving the feet a good workout every now and then is important in order to avoid problems such as plantar fasciitis. It’s also important to warm-up or cool-down after running or vigorous walking. Foot exercises may be followed by a good foot massage. This encourages circulation in the feet as well as muscle relaxation.
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 is occurring 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.
People are constantly wearing improperly-fitting shoes. Though it isn’t hard, picking the right shoes does require keeping a few things in mind.
Shoe stores have rulers so you can get an exact measurement of your feet. Be sure to always measure your feet with your shoes on. Measuring just your foot will give you a shoe size that is 1-2 inches too small for picking the right size shoe.
To ensure that your toes won’t be cramped, make sure there is wiggle room. Approximately one inch should be between your toes and the tip of your shoe. It is easy to tell if your shoes are too tight, because you will start to experience pain, blisters, and swelling.
Additionally, do not always assume your shoe size will be the same at every store. Manufacturers sometimes run differently, and your size will vary from brand to brand. Make sure the stores you purchase from have return policies, in case there is a problem.
Rather than shoe shopping in the morning, it is advised to shop for shoes later in the day. Your feet will swell as the day passes. If shoes are purchased in the morning, they may not be as snug as they should be. Furthermore, not all two feet are the same size. Therefore, accommodations may be necessary.
An overall concern in buying shoes is making sure they are comfortable and supportive. There is no such thing as a shoe being ‘broken in’. If they are uncomfortable at the store, they likely will always be uncomfortable.
Since we do a lot of walking, it is important that we pick the right shoes. Our feet will benefit from this, and we will be happier and healthier because of it.
Morton's Neuroma, also called Intermetatarsal Neuroma or Plantar Neuroma, is a condition that affects the nerves of the feet, usually the area between the third and fourth toe. Neuroma refers to a benign growth that can occur in different parts of the body. Morton's Neuroma strictly affects the feet. This condition causes the tissue around the nerves that lead to the toes becoming thick, causing pain in the ball of the foot.
This condition can be caused by injury, pressure or irritation. Normally no lump will be felt, but instead burning pain in the ball of the foot will be experienced. Numbness and tingling may also occur. With the onset of this condition, a person may feel pain when tight or narrow shoes are worn. As the condition worsens, the pain may persist for days, or even weeks.
Persistent foot pain should always be a concern. The foot should be examined by a podiatrist if pain persists longer than a few days with no relief from changing shoes. The earlier the foot is examined and treated, the less chance there will be for surgical treatment.
There are some factors that can play a role in the development of Morton's Neuroma. These include wearing ill-fitting shoes that cause pressure to the toes, such as high heels. Also, high impact exercise may contribute to the cause of this condition. Morton’s Neuroma may also develop if the foot sustains an injury. Another cause includes walking abnormally due to bunions or flat feet. This causes excessive pressure and irritates the tissue. At times, people are affected for no determinable reason.
Podiatrists can alleviate the effects of this condition using a treatment plan to help decrease the pain and heal the foot tissue. Depending upon the severity of the Morton's Neuroma, the treatment plan can vary. For cases that are mild to moderate, treatments may include applying padding to the arch to relieve pressure from the nerve and reduce compression while walking. Ice packs can also help reduce swelling. The podiatrist may also create a custom orthotic device to support the foot and reduce compression and pressure on the affected nerve. The doctor will probably advise against partaking in activities that cause constant pressure on the affected area. They may provide wider shoes to ease the pressure from the toes. If these treatments do not relieve the symptoms of this condition, the doctor may use injection therapy.
Surgical treatment may be recommended by the podiatrist if all other treatments fail to provide relief. Normally, the podiatric surgeon will decide on either a surgical procedure that involves removal of the affected nerve or will choose surgery to release the nerve. After examination, the surgeon will decide on the best approach to treat the problem.
Recovery varies according to the type of surgical procedure. The patient will also be instructed on the best shoe wear to prevent the return of this condition, along with changes to workout routines, if this was a cause. Preventative measures are important in ensuring the condition does not return.
Flip flops are often a popular choice of footwear for many people. Flip flops allow your feet to breathe and give your toes the freedom of movement. They are easy to slip on and can be worn with virtually any style of clothing. Flip flops, however, despite their many benefits, can be detrimental for your foot health.
Despite their comfortableness, frequently wearing flip flops can create problems in the lower body over time. Issues mainly stem from the fact that people walk differently in flip flops compared to other footwear, such as sneakers. This is due to a change in one’s natural gait, which therefore creates stress in different parts of the body while hindering the body’s natural posture. Problems can also arise in the arches and balls of the feet. Flip flops provide little to no support to these areas.
Aside from long-term problems, flip-fops can also create short-term issues as well, such as ankle sprains and blisters. Weak materials that are flexible and bendable are generally used to manufacture flip flops. These materials make its wearers prone to both tripping and injuring their ankles. Flip flops can create blisters as the material rubs against the foot. People are much more at risk for infection while wearing flip flops due to their openness. This also makes it easier to scrape and cut the foot since there is a lack of protection. If these cuts are left untreated and uncovered, the risk then becomes greater.
To prevent the aforementioned occurrences, purchase a pair of flip flops that offer significant protection. The soles of the flip flops should not be floppy, but sturdy and firm, and should not significantly bend or wiggle when lifted from the floor. Flip flops made of high-quality materials will not be affected by this problem. While higher quality flip flops may be more expensive, they will last longer and provide better protection compared to a cheaper pair. Brand name flip flops sold from a quality manufacturer are a dependable option.
There is no problem in wearing your favorite pair of flip flops so as long as you do not wear them daily or for extended periods of time. Flip flops should be replaced every 3-4 months to ensure that they provide your feet with the best protection.
The Achilles tendon is the strongest tendon in the human body. Its purpose is to connect the lower leg muscles and calf to the heel of the foot. This tendon is responsible for facilitating all types of movement, like walking and running. This tendon provides an enormous amount of mobility for the body. Any injuries inflicted to this tissue should be immediately brought up with a physician to prevent further damage.
The most common injuries that can trouble the Achilles tendon are tendon ruptures and Achilles tendinitis. Achilles tendinitis is the milder of the two injuries. It can be recognized by the following symptoms: inflammation, dull to severe pain, an increased flow of blood to the tendon, thickening of the tendon, and slower movement time. Tendinitis can be treated via several methods and is often diagnosed by an MRI.
An Achilles tendon rupture is trickier to heal, and is by far the most painful injury. It is caused by the tendon ripping or completely snapping. The results are immediate and absolutely devastating, and will render the patient immobile. If a rupture or tear occurs, operative and non-operative methods are available. Once the treatment begins, depending on the severity of the injury, recovery time for these types of issues can take up to a year.
Simple preventative measures can be taken as a means to avoid both injuries. Prior to any movement, taking a few minutes to stretch out the tendon is a great way to stimulate the tissue. Calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses are all suggested ways to help strengthen the lower legs and promote Achilles tendon health.
Many problems arise among athletes and people who overexert themselves while exercising. Problems can also happen among those who do not properly warm up before beginning an activity. Proper, comfortable shoes that fit correctly can also decrease tendon injuries. Some professionals also suggest that when exercising, you should make sure that the floor you are on is cushioned or has a mat. This will relieve pressure on the heels. A healthy diet will also increase tendon health.
It is very important to seek out a podiatrist if you believe you have an injury in the Achilles region. Further damage could result in severe complications that would make being mobile difficult, if not impossible.
Plantar warts are warts that are only found on the feet, hence the term “plantar”, which means “relating to the foot.” They are caused by the human papillomavirus, or HPV, and occur when this virus gets into open wounds on the feet. The warts themselves are hard bumps on the foot. They are easily recognizable, mostly found on the heels or ball of the foot. Plantar warts are non-malignant, but they can cause some pain, discomfort, and are often unsightly. Removing them is a common step toward treating them.
Plantar warts can cause some pain while standing, sometimes felt as tenderness on the sole of your foot. Unless the wart has grown into the foot behind a callus, you will be able to see the fleshy wart. A podiatrist should only be consulted if there is an excessive amount of pain. Plantar warts are not cancerous or dangerous, but they can affect your walking and continually reappear. Anyone who suffers from diabetes or a compromised immune system disease should seek out care immediately.
Podiatrists are easily able to diagnose plantar warts. They usually scrape off a tiny bit of the rough skin to make tiny blood clots visible and examine the inside of warts. However, a biopsy can be done if the doctor is not able to diagnose them from simply looking at them. Although plantar warts usually do not require an excessive amount of treatment, there are ways to go about removing them. A common method is to freeze them off using liquid nitrogen, removing them using an electrical tool, or burning them off via laser treatment. For a less invasive treatment option, topical creams can be used through a doctor’s prescription. This treatment method takes more time, however. Keep the wart covered for protection in between daily treatments.
The best way to avoid developing plantar warts is to avoid walking barefoot in public places. Avoid this especially if you have open sores or cuts on your feet. It is also important to avoid direct contact with warts in general, as they are highly contagious.
Many pregnant women complain about foot pain while they are expecting. Foot pain can primarily be caused by weight gain and hormonal changes taking place in the body. By understanding how pregnancy impacts the health of a woman's feet, a pregnant woman can take action to keep her feet as healthy and comfortable as possible.
Because a woman's weight changes during pregnancy, more pressure is brought to bear on both the legs and the feet. This weight shift can cause two major foot problems: over-pronation, also known as flat feet, as well as edema, which is swelling of the feet. Over-pronation occurs when the arch of the foot flattens, causing the foot to roll inwards when the individual is walking, and can aggravate the plantar fascia tissues located along the bottom of the feet. If these tissues become inflamed, a pregnant woman can experience pain in the heel of the foot as well as severe foot pain while walking or standing. Swelling of the feet, or edema, often occurs in the later stages of pregnancy. It is caused by slow circulation and water retention, and may turn the feet a light purple color.
To keep feet in good health and prevent over-pronation, pregnant women should avoid walking barefoot and be sure they are wearing shoes that offer good arch support. A device known as an orthotic can be added to regular footwear in order to provide additional support for the feet during pregnancy. Any expectant mother whose feet hurt should first check to see if the shoes she is wearing are old, worn out and not offering the proper support necessary for distributing the weight of her body during pregnancy.
To treat edema of the feet, a good start is to wear quality footwear which offers support and good circulation. Keep feet elevated whenever possible by using a foot stool while seated. Stay well hydrated by drinking plenty of water to prevent water retention in the feet. Any swelling that occurs in only one foot should be examined as soon as possible by a doctor.
Good foot health during pregnancy can help expectant mothers avoid foot pain that leads to other health problems. Massaging the feet and doing regular gentle exercise like walking aids foot health by contributing to good circulation. Supportive shoes are also a good investment that will support foot health during pregnancy.
Athlete’s foot is an extremely contagious infection caused by a fungus that results in itching, burning, dry, and flaking feet. The fungus that causes athlete’s foot is known as tinea pedis and thrives in moist, dark areas such as shower floors, gyms, socks and shoes, commons areas, public changing areas, bathrooms, dormitory style houses, locker rooms, and public swimming pools. Athlete’s foot is difficult to treat as well because of the highly contagious and recurrent nature of the fungus.
Tinea is the same fungus that causes ringworm, and is spread by direct contact with an infected body part, contaminated clothing, or by touching other objects and body parts that have been exposed to the fungus. Because the feet are an ideal place for tinea to grow and spread, this is the most commonly affected area. It is, however, known to grow in other places. The term athlete’s foot describes tinea that grows strictly on the feet.
The most commonly infected body parts are the hands, groin, and scalp, as well as the feet. Around 70% of the population suffer from tinea infections at some point in their lives, however not all of these cases are athlete’s foot. Just like any other ailment, some people are more likely to get it than others, such as people with a history of tinea infections or other skin infections, both recurring and non-recurring ones. The extent to which a person experiences regrowth and recurrent tinea infections varies from person to person.
Sometimes people will not even know that they are infected with tinea or that they have athlete’s foot because of a lack of symptoms. However, most experience mild to moderate flaking, itching, redness, and burning. However, some of the more severe symptoms include cracking and bleeding skin, intense itching and burning, pain while walking or standing, and even blistering.
Because of the recurring nature of the tinea fungus and the athlete’s foot it causes, the best way to treat this condition is with prevention. You can take some preventative measures such as wearing flip flops or sandals in locker rooms and public showers to reduce contact with the floor. It also helps to keep clean, dry feet while allowing them to breathe. Using powders to keep your feet dry is a good idea, as well as keeping your feet exposed to light and cool air, to prevent the growth of tinea. If you do happen to get athlete’s foot, opt for using topical medicated creams, ointments or sprays. These treatments help eliminate and prevent it from coming back.
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.
