Millions of people are affected by diabetes each year. Diabetes damages blood vessels in all parts of the body, especially the feet. The legs and feet may develop slow blood flow, which causes neuropathy, or nerve damage. Once a diabetic patient develops neuropathy, it is important that the feet are well taken care of. Otherwise, the lower limbs may have to be amputated. This only happens in drastic cases, but it shows how seriously diabetic foot care should be taken.
It is very important to always wash and dry the feet thoroughly, especially in between the toes, if you’re a diabetic. Secondly, examining your feet and toes for redness or sores must be done, even if you do not feel pain. You may also want to examine your feet from the bottom. Try to avoid wearing colored socks to prevent infections that may occur from the dye. Well-fitting socks are also highly recommended.
A diabetic’s physician should always monitor their blood levels to test how well blood sugars are being maintained. In addition to giving advice about everyday eating habits and foot care, a physician may prescribe medicine to help with the diabetic patient’s neuropathy. It is also advised to see a podiatrist if experiencing any feet conditions. Toenails may also need to be taken care of by a podiatrist. This prevents patients from cutting too deeply around their cuticles, which can lead to infection.
A person can take care of their feet at home by following the instructions of their physician. Using creams on one’s feet is also an effective way to heal dryness. Proceed with caution when using tools to remove calluses, as severe diabetics may not be able to feel pain on their feet. If any complications arise do not hesitate to contact a podiatrist.
On a daily basis, diabetic feet must be checked. If you are ever concerned about something, contact your health care professional. You never want to wait until a wound becomes too severe to treat. If left untreated, gangrene may develop. Gangrene is a serious infection that can lead to sepsis or amputation. It is also important for diabetics to be on the lookout for ulcers. Ulcers are sores that develop from tissue loss on the skin. They can be quite painful and require intensive treatment. Early treatment and everyday inspection are imperative to staying healthy.
Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.
One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.
Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.
Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.
Tarsal tunnel syndrome is a condition in which the tibial nerve, located in the tarsal tunnel in the foot, is compressed. The tibial nerve can become compressed from injury, such as an ankle sprain, flat feet, and lesions. Arthritis, diabetes, and varicose veins can also cause swelling and thus result in nerve compression.
Symptoms of tarsal tunnel syndrome include several different sensations in the sole of the foot, inside the ankle, and around the tibial nerve. These sensations include shooting pains, numbness or reduced sensation, pins and needles, burning, and tingling. Symptoms tend to worsen with greater activity to the area. In rare and severe occasions, this can change the muscles in the foot.
If you suspect you have tarsal tunnel syndrome, you should consult with your podiatrist. He or she will examine your medical history to see if you have a history of diabetes, arthritis, or flat feet. They will also check to see if you have suffered an injury to the area recently. An electrical test will be conducted to check if the nerve has been damaged. A simpler Tinel’s Test might also be used. This includes simply tapping the nerve to create a sensation. An MRI scan of the area may also be used.
Treatments vary greatly for tarsal tunnel syndrome. Treatments include both nonsurgical and surgical options depending upon the severity of the condition. Nonsurgical options include anti-inflammatory medication and steroid injections to the area. Orthotics, such as a splint or brace that immobilizes the foot, is another noninvasive option. For those with flat feet, custom shoes can be made to offer better foot support. Surgical options include a tunnel tarsal release, in which an incision is made behind the ankle down to the arch of the foot. This releases the ligament and relieves pressure off the nerve. Some doctors use a more minimally invasive surgery, where smaller incisions are made in the ankle and the ligament is stretched out.
If you are suffering from painful sensations in your foot, see a podiatrist who can determine if you are experiencing tarsal tunnel syndrome. Tarsal tunnel syndrome that is left unchecked can cause permanent nerve damage to the foot.
Ankle sprains occur when ligaments that support the ankle stretch beyond their limits and tear. These types of injuries are very common and can occur in people of all ages. Sprains may range from mild to severe, depending on how much damage is done to the ligaments. If a sprain goes untreated, a more severe sprain may occur which can further damage the ankle. Repeated ankle sprains can lead to chronic ankle pain.
There are some risk factors that can increase your risk of suffering a sprained ankle. Those who participate in sports, walk on uneven surfaces, have a prior ankle injury, are in poor physical condition, or wear improper shoes are more likely to get a sprained ankle.
There are a few symptoms to look out for if you suspect you are suffering from a sprained ankle. Some common symptoms are swelling, bruising, tenderness, and instability of the ankle. In cases where the tearing of the ligaments is severe, there may be a “popping” sound when the strain occurs.
The RICE method is proven to be effective in treating ankle sprains. RICE stands for Rest, Ice, Compression, and Elevation. Rest is important for treatment especially within the first 24 to 48 hours. You should also ice your sprained ankle for the first 48 hours for 20 minutes at a time. A small piece of cloth should be placed between the ice and the affected area. For the compression step, you should wear a brace that is snug, but not too tight that it cuts off circulation. When choosing a brace, be sure to choose one that is suitable for the type of ankle sprain you have. Lastly, you should elevate your foot above the heart as often as possible.
After you treat a sprain, you should go through rehabilitation to prevent the injury from occurring again. There are three phases to the rehab process. The first phase involves resting, protecting and reducing the swelling of the injury. The second phase consists of restoring the ankles flexibility, range of motion, and strength. The third phase consists of slowly returning to activity and maintenance exercises.
If you suspect you have an ankle sprain, you shouldn’t hesitate to consult with your podiatrist. Your podiatrist will be able to give you a proper diagnosis and a suitable treatment option for your condition.
Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.
Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.
Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.
The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatments include rest, ice or anti-inflammatory medication. A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.
Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.
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.
The feet, being the foundation of the body, carry all of the body’s weight and are therefore prone to experiencing pain and discomfort. If you are experiencing foot pain, it is important to determine where in the foot you are experiencing this pain to help discover the cause of it. While pain can be experienced virtually anywhere in the foot, the most common sites of foot pain are in the heel and ankle.
Heel pain can be due to a multitude of conditions including plantar fasciitis, Achilles tendinitis, and heel spurs. Pain experienced in the ankle can be a sign of an ankle sprain, arthritis, gout, ankle instability, ankle fracture, or nerve compression. In more serious cases, pain in the foot can be a sign of improper alignment or an infection.
Foot pain can be accompanied by symptoms including redness, swelling, stiffness and warmth in the affected area. Whether the pain can be described as sharp or dull depends on the foot condition behind it. It is important to visit your local podiatrist if your foot pain and its accompanying symptoms persist and do not improve over time.
Depending on the location and condition of your foot pain, your podiatrist may prescribe certain treatments. These treatments can include but are not limited to prescription or over-the-counter drugs and medications, certain therapies, cortisone injections, or surgery.
If you are experiencing persistent foot pain, it is important to consult with your foot and ankle doctor to determine the cause and location. He or she will then prescribe the best treatment for you. While milder cases of foot pain may respond well to rest and at-home treatments, more serious cases may take some time to fully recover.
Trauma to the foot, especially the toes, can occur in many ways. Banging them, stubbing them, or dropping something on them are a few different ways this trauma can occur. Given the fact that toes are positioned in front of the feet, they typically sustain the brunt of such trauma. When trauma occurs to a toe, the result can be a painful break or fracture. Another type of trauma that can break a toe is repeated activity that places stress on the toe for prolonged periods of time.
Broken toes can be categorized as either minor or severe fractures. Symptoms of minor toe fractures include throbbing pain, swelling, bruising on the skin and toenail, and the inability to move the toe with ease. Severe toe fractures require medical attention and are indicated when the broken toe appears crooked or disfigured, when there is tingling or numbness in the toe, or when there is an open, bleeding wound present on the toe.
Generally, a minor toe break will heal without long-term complications. However, it is important to discontinue activities that put pressure on the toe. It is best to stay off of the injured toe and immediately get a splint or cast to prevent any more additional movement of the toe bones. You can also immobilize your toe by placing a small cotton ball between the injured toe and the toe beside it. Then, tape the two toes together with medical tape. Swelling can be alleviated by placing an ice pack on the broken toe directly as well as elevating your feet above your head.
Severe toe fractures may be treated with a splint, cast, and in some cases, minor surgery, especially when the big toe has been broken. Due to its position and the pressure the big toe endures with daily activity, future complications can occur if it is not properly treated. Pain associated with minor toe fractures can be managed with over-the-counter pain medications. Prescription pain killers may be necessary for severe toe fractures.
The healing time for a broken toe is approximately four to six weeks. In severe cases where the toe becomes infected or requires surgery, healing time can take up to eight weeks or more. While complications associated with a broken toe are immediately apparent, it is important to note that there are rare cases when additional complications, such as osteoarthritis, can develop over time. You should immediately speak with your podiatrist if you think you have broken your toe due to trauma. They will be able to diagnose the injury and recommend the appropriate treatment options.
Obesity is a common problem in American society. Approximately one third of the U.S. population is obese. Obesity is defined as a body mass index greater than 30. Obesity has the power to affect different aspects of the body, and one of the most common problems it causes is foot pain. There have been many studies that found a connection between an increased BMI and foot problems. A simple activity such as walking up a flight of stairs can increase pressure on the ankle by four to six times.
Being overweight causes the body to compensate for the extra weight by changing the way it moves. Consequently, people who struggle with obesity commonly have arch problems in their feet. Obesity causes the arch to break by stretching the ligaments and tendons that hold the bones in the foot together. When the arch lowers, the foot may eventually fall flat. Collapsed foot arches fail to provide adequate shock absorption which eventually leads to foot pain. Other conditions that may be caused by flat feet are pronation, plantar fasciitis, weak ankles, and shin splints.
Foot problems that are caused by obesity may be treated by wearing proper footwear. Proper shoes will allow your feet to have better circulation around the arch and ankle. Additionally, those with obesity often discover that typical heel pain remedies are not effective for them. They will find that their plantar fascia is easily injured, and it is often inflamed. The best way to treat this problem is to implement lifestyle changes. A few good ways to improve your diet are to reduce calories, fill up on fruits and veggies, and to limit sugars.
Custom foot orthotics can prevent foot problems if you’re carrying excess weight or are trying to lose weight. The purpose of orthotics is to provide shock absorption to decrease the amount of stress on the joints to prevent arthritis.
Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters. Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.
Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.
Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.
To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

The branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.
To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.
When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.
Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.
Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.
Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.
A bunion is a bump that forms at the base of the big toe. Bunions form when the big toe pushes against the next toe, which forces the big toe joint to get bigger and stick out. As a result, the skin over the bunion may start to appear red and it may feel sore.
There are risk factors that can increase your chances of developing bunions. People who wear high heels or ill-fitting shoes are more likely to develop them, in addition to those who have a genetic history of bunions or have rheumatoid arthritis.
The most obvious way to tell if you have a bunion is to look for the big toe pushing up against the toe next to it. Bunions produce a large protrusion at the base of the big toe and may or may not cause pain. Other symptoms are redness, swelling, and restricted movement of the big toe if you have arthritis.
Nonsurgical methods are frequently used to treat bunions that aren’t severe. Some methods of nonsurgical treatment are orthotics, icing and resting the foot, taping the foot, and pain medication. Surgery is usually only required in extreme cases. However, if surgery is needed, some procedures may involve removing the swollen tissue from around the big toe joint, straightening the big toe by removing part of the bone, or joining the bones of your affected joint permanently.
Your podiatrist will diagnose your bunion by doing a thorough examination of your foot. He or she may also conduct an x-ray to determine the cause of the bunion and its severity.
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.
Sports Related Foot and Ankle Injuries
Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.
Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.
Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.
Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.
It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.
