Typically, running shoes are made with considerably heavier cushioning than walking shoes. Fitness walkers have different needs than runners, as walking has much less impact on the feet. One thing to look for when buying running shoes is to make sure the foot can bend in the shoe. Another suggestion is to look for a shoe with a low heel; this can support runners who land on the balls of their feet. Cushioned shoes are favored for those who walk long distances or on hard surfaces. Additionally, shoes that are made from lighter materials will be more comfortable because they are not as heavy.
For more information about walking shoes versus running shoes, consult with Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can measure your feet to determine what your needs are and help you find an appropriate pair of footwear.
Foot Health: The Differences between Walking & Running Shoes
There are great ways to stay in shape: running and walking are two great exercises to a healthy lifestyle. It is important to know that running shoes and walking shoes are not interchangeable. There is a key difference on how the feet hit the ground when someone is running or walking. This is why one should be aware that a shoe is designed differently for each activity.
You may be asking yourself what the real differences are between walking and running shoes and the answers may shock you.
Walking doesn’t involve as much stress or impact on the feet as running does. However, this doesn’t mean that you should be any less prepared. When you’re walking, you land on your heels and have your foot roll forward. This rolling motion requires additional support to the feet.
Flexibility – Walking shoes are designed to have soft, flexible soles. This allows the walker to push off easily with each step.

There are many things that get neglected as we get older, and the feet are one of them. The overall health of an elderly person may be improved with proper foot care, which may include toenail cutting, moisturizing, and inspecting the feet. This is especially true for diabetic patients. Foot problems are common due to years of wear and tear. Shoes can be a critical factor in keeping the feet properly supported, in addition to helping prevent poor circulation. It is important to keep your toenails trimmed as improperly trimmed toenails can be more likely to break or cause other issues. To prevent foot problems, have your feet checked regularly by a podiatrist. It’s also beneficial to have your feet elevated while sitting or lying down. Additionally, a gentle foot massage or foot soak may help ease pain and keep your feet clean. Please consult a podiatrist if you have questions or concerns about common foot conditions and care.
Proper foot care is something many older adults forget to consider. If you have any concerns about your feet and ankles, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
The Elderly and their Feet
As we age we start to notice many changes in our body, but the elder population may not notice them right away. Medical conditions may prevent the elderly to take notice of their foot health right away. Poor vision is a lead contributor to not taking action for the elderly.
- Neuropathy – can reduce feeling in the feet, and can hide many life threating medical conditions.
- Reduced flexibility – prevents the ability of proper toenail trimming, and foot cleaning. If left untreated, it may lead to further medical issues.
- Foot sores – amongst the older population can be serious before they are discovered. Some of the problematic conditions they may face are:
- Gouging toenails affecting nearby toe
- Shoes that don’t fit properly
- Pressure sores
- Loss of circulation in legs & feet
- Edema & swelling of feet and ankles
Diabetes and poor circulation can cause general loss of sensitivity over the years, turning a simple cut into a serious issue.

When you increase the amount of friction on the foot, you also increase the risk of getting blisters. Blisters can originate from many sources, including socks, sweat, shoes and restricted foot motion. It’s important to have adequate toe room in the shoe; this can lessen friction, therefore preventing blisters. When proper insoles are worn, fewer blisters may occur. Additionally, wearing the correct socks, such as synthetic or wool socks, can be important in reducing skin friction. Sweat can also be a factor in producing blisters and typically happens in the warmer months. Using an antiperspirant may aid in producing less sweat, and fewer blisters may occur.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Dr. Harris L. Klear of Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often lead to pain.
What are Foot Blisters?
A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.
How do Blisters Form?
Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.
Prevention & Treatment
It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.
If you have any questions, please feel free to contact one of our offices located in Marlton and Delran, NJ. We offer the newest diagnostic and treatment technologies for all your foot care needs.Read more about Blisters on the Feet
For many people, buying larger shoes over time is common, as they may gain a half shoe size over the age of 40. There are many bones, joints, and over 100 tendons in the foot. The ligaments may lose their elasticity, which may cause the feet to flatten, and the arches to lower. Additionally, the force of the body weight causes the “fat pads” to thin, which cushion the bottom of the feet. There’s a few important pointers to remember when buying shoes. The feet are largest at the end of the day, which makes it a good time to measure the foot. Typically, there should be a half-inch of space for the longest toe while standing. Also, it's beneficial if the shoes are made from soft material that conforms to the shape of the foot. They should fit comfortably and not slip as you walk. Lastly, walking in the shoes on carpeting is a good way to make sure they feel right.
Getting the right shoe size is an important part of proper foot health. Seek the assistance of Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor will provide the care you need to keep you pain-free and on your feet.
Getting the Right Shoe Size
There are many people who wear shoes that are the incorrect size, negatively affecting their feet and posture. Selecting the right shoes is not a difficult process, so long as you keep several things in mind when it comes to choosing the right pair.
- When visiting the shoe store, use the tools available to measure your foot.
- Be sure there is ‘wiggle room’. There should be about an inch between your toes and the tip of your shoes.
- Do not always assume you are the same size, as manufacturers run differently.
- Purchase shoes later in the day, as your feet swell as the day progresses.
- If a shoe is not comfortable, it is not suitable. Most shoes can’t be ‘broken in’, and comfort should be the ultimate goal when it comes to choosing the right pair of shoes
As our feet hold our body weight and keep us moving, it is important to treat them right. Picking the right pair of shoes can provide your feet comfort and mobility without pain.
If you have any questions, please feel free to contact one of one of our offices located in Marlton and Delran, NJ. We offer the newest diagnostic and treatment technologies for all your foot care needs.Read more about Getting the Right Shoe Size: To Keep Your Feet Happy
While it may seem obvious how to clip your toenails, many people clip them the wrong way. Clipping your toenails improperly can cause the nail to become ingrown. While generally not serious, it can cause pain and discomfort. If you are a diabetic, an ingrown toenail can be a serious health risk, and it is advised to see a podiatrist if you have one. To help prevent ingrown toenails, cut them straight across and not as a rounded edge. Furthermore, do not clip them too short as this can also increase the risk of an ingrown toenail. Lastly, wearing shoes that don’t press against your toenails can help prevent the nail from becoming compressed and ingrown.
Ingrown toenails can become painful if they are not treated properly. For more information about ingrown toenails, contact Dr. Harris L. Klear of Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Ingrown toenails occur when a toenail grows sideways into the bed of the nail, causing pain, swelling, and possibly infection.
- Bacterial infections
- Improper nail cutting such as cutting it too short or not straight across
- Trauma to the toe, such as stubbing, which causes the nail to grow back irregularly
- Ill-fitting shoes that bunch the toes too close together
- Genetic predisposition
Because ingrown toenails are not something found outside of shoe-wearing cultures, going barefoot as often as possible will decrease the likeliness of developing ingrown toenails. Wearing proper fitting shoes and using proper cutting techniques will also help decrease your risk of developing ingrown toenails.
Ingrown toenails are a very treatable foot condition. In minor cases, soaking the affected area in salt or antibacterial soaps will not only help with the ingrown nail itself, but also help prevent any infections from occurring. In more severe cases, surgery is an option. In either case, speaking to your podiatrist about this condition will help you get a better understanding of specific treatment options that are right for you.

Our feet are an essential part of our bodies, and it’s important to remember to keep an eye out for possible problems. Muscle spasms and foot cramps can be a sign of dehydration so be sure to stay hydrated, especially during periods of physical activity. Gout, a form of arthritis, can cause the big toe joint to become inflamed; this can cause pain. It is best to see a podiatrist for diagnosis and treatment for gout. If your feet are cold, this can be from poor blood circulation; this could possibly stem from diabetes, anemia, or hypothyroidism. Swollen feet can occur while pregnant or be caused by poor circulation from a blood clot, lymphatic buildup, or cellulitis. If you are experiencing nerve loss or a pins and needles sensation in your feet, you could be experiencing neuropathy; this can be caused by diabetes. Once again it is best to see a podiatrist if you have any of these symptoms. Finally, colored toenails can be a sign of psoriasis or toenail fungus. There are topical creams for toenail fungus; but once again, a podiatrist can offer better treatment options and a more thorough diagnosis.
Everyday foot care is very important to prevent infection and other foot ailments. If you need your feet checked, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Everyday Foot Care
Often, people take care of their bodies, face and hair more so than they do for their feet. But the feet are a very important aspect of our bodies, and one that we should pay more attention to. Without our feet, we would not be able to perform most daily tasks.
It is best to check your feet regularly to make sure there are no new bruises or cuts that you may not have noticed before. For dry feet, moisturizer can easily be a remedy and can be applied as often as necessary to the affected areas. Wearing shoes that fit well can also help you maintain good foot health, as well as making it easier to walk and do daily activities without the stress or pain of ill-fitting shoes, high heels, or even flip flops. Wearing clean socks with closed shoes is important to ensure that sweat and bacteria do not accumulate within the shoe. Clean socks help to prevent Athlete’s foot, fungi problems, bad odors, and can absorb sweat.

Stress fractures are small hairline fractures in the bone that most often occur from overuse. When the muscles in the body are fatigued, they can become unable to handle repeated shocks to the area. The shock instead transfers to the bone, which can crack. Most often, stress fractures occur in areas of the lower body like the feet and legs. The most common symptom of a stress fracture is pain in the area. If you are experiencing pain in the foot and ankle and think you may have a stress fracture, it is recommended to see a podiatrist. Rest is often the number one method in helping a stress fracture heal. Braces, pain medication, and ice may also be recommended, though not always. To prevent stress fractures, it is advised to start any new athletic activity slowly, gradually work your way up, and stop if you feel pain or have been pushing yourself with little rest.
Activities where too much pressure is put on the feet can cause stress fractures. To learn more, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep your pain free and on your feet.
Dealing with Stress Fractures of the Foot and Ankle
Stress fractures occur in the foot and ankle when muscles in these areas weaken from too much or too little use. The feet and ankles then lose support when walking or running from the impact of the ground. Since there is no protection, the bones receive the full impact of each step. Stress on the feet can cause cracks to form in the bones, thus creating stress fractures.
What are Stress Fractures?
Stress fractures occur frequently in individuals whose daily activities cause great impact on the feet and ankles. Stress factors are most common among:
- People affected with Osteoporosis
- Tennis or basketball players
- High impact workouts
Pain from the fractures occur in the area of the fractures and can be constant or intermittent. It will often cause sharp or dull pain with swelling and tenderness. Engaging in any kind of activity which involves high impact will aggravate pain.
As if things couldn’t get any worse for the New York Giants, they just lost wide receiver Dwayne Harris. Harris was injured during the second half of the Giants vs Los Angeles Chargers game. He is expected to miss the rest of the season. Fellow wide receivers Sterling Shepard, Brandon Marshall, and Odell Beckham Jr. all sustained some sort of foot or ankle injury during the same game. The Giants are currently 0 and 5 and will have to continue the season with a quickly strung together group of wide receivers.
A broken foot requires immediate medical attention and treatment. If you need your feet checked, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Broken Foot Causes, Symptoms, and Treatment
A broken foot is caused by one of the bones in the foot typically breaking when bended, crushed, or stretched beyond its natural capabilities. Usually the location of the fracture indicates how the break occurred, whether it was through an object, fall, or any other type of injury.
Common Symptoms of Broken Feet:
- Blue in color
Those that suspect they have a broken foot shoot seek urgent medical attention where a medical professional could diagnose the severity.
Treatment for broken bones varies depending on the cause, severity and location. Some will require the use of splints, casts or crutches while others could even involve surgery to repair the broken bones. Personal care includes the use of ice and keeping the foot stabilized and elevated.
Working out and building strength is a good way to help prevent running injuries. Here are a couple of workouts you can try to help build muscle in your feet and legs. Do each of these exercises for and 4 to 5 sets of 15 to 25 repetitions . Before you do these however, it is recommended you see a podiatrist first and ask if exercising is right for you. To do a toe-curl walk, stand barefoot and move forward with your right leg using only your toes, then do the same for the left foot; you will only move an inch or so while doing this. Heel raises are easy to do. Just stand up on your toes while keeping your heels off the ground for about 1 second and then come down. Chair squats are a good way to work your quadriceps. Place a non-rolling chair behind you, and squat down over it so that your butt only briefly touches the chair. Then come up. Finally, to workout your gluteus muscles, lay on your stomach and bend your knee at a 90 degree angle. Slowly raise your thigh off the ground for a couple of seconds, then bring down your thigh and repeat with the other leg. These exercises are quick and easy to do and will build strength that will further help prevent running injuries.
Exercising your feet regularly with the proper foot wear is a great way to prevent injuries. If you have any concerns about your feet, contact Dr. Harris L. Klear of Burlington County Podiatry Associates. Our doctor will treat your foot and ankle needs.
How to Prevent Running Injuries
Many common running injuries are caused by overuse and overtraining. When the back of the kneecap starts wearing out and starts causing pain in your knee, this is commonly referred to as runner’s knee. Runner’s knee is a decrease in strength in your quadriceps and can occur if you’re not wearing properly fitted or supporting shoes. To prevent runner’s knee, focusing on hip strengthening is a good idea, as well as strengthening your quads to keep the kneecaps aligned.
What Are Some Causes of Running Injuries?
- One cause of a common running injury is called iliotibial band syndrome.
- Plantar fasciitis is also another common injury.
- Stress fractures can occur from overtraining, lack of calcium, or even your running style.
Best Ways to Prevent Running Injuries
- Wear footwear that fits properly and suits your running needs.
- Running shoes are the only protective gear that runners have to safeguard them from injury.
- Make a training schedule. Adding strengthening exercises as well as regular stretching can help keep you strong and limber and can lessen the possibility of injuries.
- Stretching keeps muscles limber; this will help you gain better flexibility.
Athlete’s foot is a skin infection caused by fungus. As the name implies, it is common among athletes; this is mainly due to the fact that locker rooms, pools, and public showers are likely to harbor the fungus. The fungus also prefers moist, warm, and dark areas such as in between the toes on feet that are generally covered with shoes. While the infection usually first occurs between the toes, it can spread to the rest of the foot. Symptoms include redness, itchiness, burning sensations, and peeling skin. If scratched, the fungus can spread to other parts of the body like nails. To prevent athlete’s foot, keep your feet dry. If your feet sweat a lot, change socks frequently to prevent moisture buildup. Once you are finished showering or out of the pool, dry the feet thoroughly. Finally, wear shoes that allow the feet to "breathe” to help prevent sweat and allow the feet to cool down.
Athlete’s foot is an inconvenient condition that can be easily reduced with the proper treatment. If you have any concerns about your feet and ankles, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor will treat your foot and ankle needs.
Athlete’s Foot: The Sole Story
Athlete's foot, also known as tinea pedis, can be an extremely contagious foot infection. It is commonly contracted in public changing areas and bathrooms, dormitory style living quarters, around locker rooms and public swimming pools, or anywhere your feet often come into contact with other people.
Solutions to Combat Athlete’s Foot
- Hydrate your feet by using lotion
- Buff off nails
- Use of anti-fungal products
- Examine your feet and visit your doctor if any suspicious blisters or cuts develop
Athlete’s foot can cause many irritating symptoms such as dry and flaking skin, itching, and redness. Some more severe symptoms can include bleeding and cracked skin, intense itching and burning, and even pain when walking. In the worst cases, Athlete’s foot can cause blistering as well. Speak to your podiatrist for a better understanding of the different causes of Athlete’s foot, as well as help in determining which treatment options are best for you.
The Achilles tendon, while the largest and thickest tendon in the body, is prone to being injured just like any body part. Tendinopathy, the breakdown of the tendon, generally occurs from overuse—especially from athletic activities. In some cases, the tendon can even rupture completely. While overuse directly causes the injury, there are other factors that increase the risk. These factors include bending the foot backwards, or dorsiflexion, weak calf muscles, and pronation. Compared to other muscle recoveries, tendons take longer to heal and can even take up to a year to fully recover. While anti-inflammatory medication may bring relief, it will not heal the injury. Ultimately, the best thing to do for an Achilles tendon injury is to see a podiatrist. Podiatrists offer the best treatment options and recovery programs for such injuries, and they can help patients heal properly so they can get back in the game.
Achilles tendon injuries need immediate attention to avoid future complications. If you have any concerns, contact Dr. Harris L. Klear of Burlington County Podiatry Associates. 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
- Dull to severe pain
- Increased blood flow to the tendon
- Thickening of the tendon
- 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
If you have any questions please feel free to contact one of our offices located in Marlton and Delran, NJ. We offer the newest diagnostic tools and technology to treat your foot and ankle needs.Read more about What are Achilles Tendon Injuries
Plantar fasciitis and heel pain can both be very painful and uncomfortable. While stretching won’t eliminate the pain, it can help mitigate it. Some stretches that you can perform include the quadruped stretch, isolated calf raise, and even a foot massage. Before you do these, ask your podiatrist whether stretching is right for you. To do a quadruped stretch, get on all fours and spread your toes on the floor. Next, lean back slowly and sit on your heels while holding this position for 30 seconds. For isolated calf raises, lunge with your left leg forward and right leg back. Then, with your right foot flat, lift up onto the ball of your right foot. Do this for 10-15 reps on each side and for three repetitions. To massage your foot, push down on the center of the bottom of the foot and use a circular motion while applying pressure. These stretches will not eliminate plantar fasciitis and are only meant to temporarily reduce pain. If you have heel pain, it is recommended that you see a podiatrist who can offer effective treatment strategies.
Plantar fasciitis can be very painful and inconvenient. If you are experiencing heel pain or symptoms of plantar fasciitis, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
What is Plantar Fasciitis?
Plantar fasciitis is the inflammation of the thick band of tissue that runs along the bottom of your foot, known as the plantar fascia, and causes mild to severe heel pain.
What Causes Plantar Fasciitis?
- Excessive running
- Non-supportive shoes
- Repeated stretching and tearing of the plantar fascia
How Can It Be Treated?
- Conservative measures – anti-inflammatories, ice packs, stretching exercises, physical therapy, orthotic devices
- Shockwave therapy – sound waves are sent to the affected area to facilitate healing and are usually used for chronic cases of plantar fasciitis
- Surgery – usually only used as a last resort when all else fails. The plantar fascia can be surgically detached from the heel
While very treatable, plantar fasciitis is definitely not something that should be ignored. Especially in severe cases, speaking to your doctor right away is highly recommended to avoid complications and severe heel pain. Your podiatrist can work with you to provide the appropriate treatment options tailored to your condition.
While the Kansas City Chiefs may have recently won against the New England Patriots, they lost a valuable player in the process. Chiefs’ safety, Eric Berry, injured the Achilles tendon in his left foot during the game. The injury will unfortunately take Berry out for the rest of the season. Berry is the highest paid safety in the league and one of the Chiefs’ best players. Losing him this early in the season is a big blow to the team.
Sports related foot and ankle injuries require proper treatment before players can go back to their regular routines. For more information, contact Dr. Harris L. Klear of Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Sports Related Foot and Ankle Injuries
Foot and ankle injuries are a common occurrence when it comes to athletes of any sport. While many athletes dismiss the initial aches and pains, the truth is that ignoring potential foot and ankle injuries can lead to serious problems. As athletes continue to place pressure and strain the area further, a mild injury can turn into something as serious as a rupture and may lead to a permanent disability. There are many factors that contribute to sports related foot and ankle injuries, which include failure to warm up properly, not providing support or wearing bad footwear. Common injuries and conditions athletes face, including:
- Plantar Fasciitis
- Plantar Fasciosis
- Achilles Tendinitis
- Achilles Tendon Rupture
- Ankle Sprains
Sports related injuries are commonly treated using the RICE method. This includes rest, applying ice to the injured area, compression and elevating the ankle. More serious sprains and injuries may require surgery, which could include arthroscopic and reconstructive surgery. Rehabilitation and therapy may also be required in order to get any recovering athlete to become fully functional again. Any unusual aches and pains an athlete sustains must be evaluated by a licensed, reputable medical professional.
Choosing the right running shoes for you can mean the difference between comfort and potential injury. Not all running shoes are built the same. They vary not just in foot size and style but also in the surfaces they were designed for. If you run on trails, a trail running shoe is a better choice than a running shoe designed for roads or the track. The shoe should have enough space so your feet aren’t cramped but should still be snug. Knowing whether your foot rolls in too much (overpronation), rolls out too much (underpronation), or stays where it is (neutral) when you step can also determine what shoe is right for you. However it is advised to not worry too much about foot roll. The most important part is comfort. You should be able to wear the shoes for long periods without feeling pain or discomfort.
If you are a runner, wearing the right running shoe is essential. For more information, contact Dr. Harris L. Klear from Burlington County Podiatry Associates. Our doctor can provide the care you need to keep you pain-free and on your feet.
Choosing the Right Running Shoe for Your Foot Type
To increase performance and avoid the risk of injury, it is important to choose the right running shoe based on your foot type. The general design of running shoes revolves around pronation, which is how the ankle rolls from outside to inside when the foot strikes the ground.
- Neutral runners are able to choose from a wide variety of shoes, including minimalist shoes or even going barefoot.
- Runners who overpronate, or experience an over-abundance of ankle rolling, should choose shoes that provide extra motion control and stability.
- Runners who underpronate, or supinate, have feet that have high arches and lack flexibility, preventing shock absorption. They require shoes with more flexibility and cushion.
