Flip Flops and Your Feet
When the weather heats up, you may want to start wearing flip-flops. However, it has been proven that these are not the ideal shoes in terms of preserving the health of your feet.
Flip flops are known to expose your feet to different types of bacteria and fungal infections. When you wear your flip flops in public, you are exposing them to staphylococcus which is a skin-irritating bacterium. Athlete’s foot is also highly contagious and can be spread when you walk around nearly-barefoot.
Another harmful effect of wearing flip-flops is that they develop blisters on the feet. This is because the thin strap rubs against the skin with each step taken. Unfortunately, when blisters pop, they cause you to be more vulnerable to pathogens you pick up by having your feet exposed.
These shoes may also cause “shooting pains”. If you have flat feet, you need arch support to keep your knees, hips, and back in alignment. If you wear flat shoes, your joints are forced to compensate which can cause injuries throughout the body.
If you constantly wear flip-flops, you should avoid doing so as they can lead to many problems for your feet. If you are experiencing any of these foot issues, you should seek help from a podiatrist right away.
Dealing With Plantar Warts

A wart is a growth on the skin that is caused by contact with a virus, namely the human papilloma virus, or HPV. Warts can grow anywhere on the body, but when they are on the feet, they are known as plantar warts. They look a bit like a callus that is growing on the bottom of the foot. Although plantar warts are not generally painful, they can be irritated by pressure on the ball of the foot. Since warts are contagious, it is a good idea not to touch them with bare hands, because the virus easily can spread to another body part. Plantar warts appear as patches of skin with dark spots. When they form as a cluster, they are known as mosaic warts. A plantar wart will likely go away on its own, but that may take some time, even as long as a year. If non-prescription medication is not effective after a few months, or if the wart looks to be infected, it is a good idea to seek medical help. A podiatrist can examine the area and remove the wart by freezing it, applying medication, or in some cases performing surgery.
Plantar warts can be very uncomfortable. If you need your feet checked, contact Dr. Kirk Sherris from Liberty Bay Foot & Ankle. Our doctor will assist you with all of your foot and ankle needs.
About Plantar Warts
Plantar warts are the result of HPV, or human papillomavirus, getting into open wounds on the feet. They are mostly found on the heels or balls of the feet.
While plantar warts are generally harmless, those experiencing excessive pain or those suffering from diabetes or a compromised immune system require immediate medical care. Plantar warts are easily diagnosed, usually through scraping off a bit of rough skin or by getting a biopsy.
Symptoms
- Lesions on the bottom of your feet, usually rough and grainy
- Hard or thick callused spots
- Wart seeds, which are small clotted blood vessels that look like little black spots
- Pain, discomfort, or tenderness of your feet when walking or standing
Treatment
- Freezing
- Electric tool removal
- Laser Treatment
- Topical Creams (prescription only)
- Over-the-counter medications
To help prevent developing plantar warts, avoid walking barefoot over abrasive surfaces that can cause cuts or wounds for HPV to get into. Avoiding direct contact with other warts, as well as not picking or rubbing existing warts, can help prevent the further spread of plantar warts. However, if you think you have developed plantar warts, speak to your podiatrist. He or she can diagnose the warts on your feet and recommend the appropriate treatment options.

All About Plantar Warts
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.
Achilles Tendon Pain

The Achilles tendon connects the muscles of the calf and lower leg to the heel bone. When it is stretched beyond its limits, it can become inflamed (called tendonitis) or tear (also known as a rupture). Injuries to the Achilles tendon can cause mild to severe pain and stiffness. Achilles tendonitis can come on from a variety of reasons, including sudden increase in exercise, insufficient stretching of the calf muscle, flat feet, a bony spur on the back of the ankle, or leg length differences. The pain one feels with this inflammatory condition can be felt near the bottom of the calf muscle, along the tendon, or near the heel bone and is described as a burning sensation that worsens with activity. There may be mild swelling and warmth in the affected area and some stiffness, especially before warming up. Untreated, tendonitis can progress to tendinosis, which is when the collagen fibers that make up the tendon break down. There is no inflammation with tendinosis, but scar tissue may result from this and lead to permanent thickening. An Achilles tendon rupture is rarer but happens when the tendon fibers tear and separate completely or in part. This can occur from sudden force being exerted on the tendon, severe overstretching causing the tendon to tear, or taking a type of antibiotic called fluoroquinolones. This will bring on severe heel pain and an inability to walk or bear weight on the foot. If you feel Achilles tendon pain, it is best to consult with a podiatrist for a proper diagnosis and treatment that is right for you.
Achilles tendon injuries need immediate attention to avoid future complications. If you have any concerns, contact Dr. Kirk Sherris of Liberty Bay Foot & Ankle. Our doctor can provide the care you need to keep you pain-free and on your feet.
What Is the Achilles Tendon?
The Achilles tendon is a tendon that connects the lower leg muscles and calf to the heel of the foot. It is the strongest tendon in the human body and is essential for making movement possible. Because this tendon is such an integral part of the body, any injuries to it can create immense difficulties and should immediately be presented to a doctor.
What Are the Symptoms of an Achilles Tendon Injury?
There are various types of injuries that can affect the Achilles tendon. The two most common injuries are Achilles tendinitis and ruptures of the tendon.
Achilles Tendinitis Symptoms
- Inflammation
- Dull to severe pain
- Increased blood flow to the tendon
- Thickening of the tendon
Rupture Symptoms
- Extreme pain and swelling in the foot
- Total immobility
Treatment and Prevention
Achilles tendon injuries are diagnosed by a thorough physical evaluation, which can include an MRI. Treatment involves rest, physical therapy, and in some cases, surgery. However, various preventative measures can be taken to avoid these injuries, such as:
- Thorough stretching of the tendon before and after exercise
- Strengthening exercises like calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses

Achilles Tendon Injuries
The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.
The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.
A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.
If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.
What is Morton's Neuroma?
Morton’s neuroma, (also referred to as Morton’s metatarsalgia, Morton’s neuralgia, plantar neuroma or intermetatarsal neuroma) is a condition that is caused when the tissue around one of the nerves between your toes begins to thicken. This thickening can result in pain in the ball of the foot. Fortunately, the condition itself is not cancerous.
Morton’s neuroma affects women more often than men with a ratio of 4:1. It tends to target women between the age of 50 and 60, but it can occur in people of all ages. There are some risk factors that may put you at a slightly higher risk of developing the condition. People who often wear narrow or high-heeled shoes are often found to be linked to Morton’s neuroma. Additionally, activities such as running or jogging can put an enormous amount of pressure on the ligament and cause the nerve to thicken.
There usually aren’t any outward symptoms of this condition. A person who has Morton’s neuroma may feel as if they are standing on a pebble in their shoe. They may also feel a tingling or numbness in the toes as well as a burning pain in the ball of their foot that may radiate to their toes.
In order to properly diagnose you, the doctor will press on your foot to feel for a mass or tender spot. He may also do a series of tests such as x-rays, an ultrasound, or an MRI. X-rays are usually done to rule out any other causes for your foot pain such as a stress fracture. Ultrasounds are used to reveal soft tissue abnormalities that may exist, such as neuromas. Your podiatrist may want to use an MRI in order to visualize your soft tissues.
There are three main options for treatment of Morton’s neuroma: Injections, decompression surgery, and removal of the nerve. Injections of steroids into the painful area have been proven to help those with Morton’s neuroma. Decompression surgery has been shown to relieve pressure on the affected nerve by cutting nearby structures such as the ligaments in the foot. Another treatment option would be to surgically remove the growth to provide pain relief.
If you suspect that you have Morton’s neuroma you should make an appointment with your podiatrist right away. You shouldn’t ignore any foot pain that lasts longer than a few days, especially if the pain does not improve.
Foot Biomechanics 101

The study of how the foot moves through the gait cycle is called foot biomechanics. This is important in making sure your feet do not overpronate or over-supinate so the feet absorb shock when they hit the ground and propel forward movement properly. If the foot overpronates, it causes the foot to flatten too much and the ankle and knee to roll inward. This can increase the risk of injury and cause lower leg, hip, and back injuries. If the foot does over-supinate, it fails to roll in or flatten sufficiently and will not be able to absorb shock. Those who over supinate have high arches and less flexible feet. To prevent injuries from occurring from improper pronation, visit a podiatrist who can access your gait and analyze how your foot works. If something is wrong, a podiatrist can provide the proper treatment.
If you have any concerns about your feet, contact Dr. Kirk Sherris from Liberty Bay Foot & Ankle. Our doctor can provide the care you need to keep you pain-free and on your feet.
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 structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.
A History of Biomechanics
- Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
- 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 or conditions could be implemented to gain strength and coordination in the area.
Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.
Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Working on Your Feet
Foot care is important regardless of your profession, but those who work on their feet must pay special attention. Bunions, calluses, blisters, and plantar warts are just a few of the many conditions that can arise after standing all day. While painful at their worst, these conditions can easily be avoided with the right foot care. This includes both appropriate footwear and proper posture—important elements that affect the health of your feet.
Choosing appropriate footwear means choosing a shoe that has a negative heel. This means that the heel is slightly lower than the ball of your foot, which places less of a strain. If you have a profession that requires you to be on your feet all day, investing in a pair of high-quality shoes is pertinent. High-quality shoes can be purchased from a respected manufacturer that emphasizes foot care and foot health.
Despite the regularity of wearing shoes, the feet are naturally not designed to be enclosed. Regular “barefoot” time for your feet can be beneficial for foot health. Among other methods, allowing your feet to breathe can help alleviate the pain and pressure your feet may be experiencing from being on your feet all day.
Simple foot exercises and yoga positions can help improve both the health and function of your feet. Active foot exercises that create movement will stimulate your foot’s blood flow and circulation, and yoga positions that place your feet flat onto the floor will stretch out their muscles. Yoga is particularly beneficial for your Achilles tendon and calf muscles, which are areas that can become especially problematic if not taken care of. Foot exercises and yoga positions can be easily performed every day at virtually any location and any time; whether it is at the office, at the gym, or at home right before you go to bed. Simple stretching can increase your foot health by miles.
The foot pain you experience after lengthy hours working on your feet may seem inevitable and unavoidable; in reality, however, that is not the case. Wearing proper footwear and performing simple foot exercises and stretches can help ease foot pain and allow you to truly avoid frustrating foot problems.
Your feet can easily be kept healthy with some education and a little effort. Pain that begins at the feet can eventually affect the whole body. Begin taking care of your feet now!
