A black toenail, medically referred to as a subungual hematoma, develops when blood becomes trapped beneath the nail due to repeated trauma. This condition is especially common among runners who engage in frequent or long-distance training. The constant forward motion of the foot inside a shoe causes the toes to repeatedly strike the front, leading to bruising under the nail. Over time, this repetitive impact can damage the nail bed and result in noticeable discoloration.

Early symptoms often include tenderness, pressure, and mild discomfort in the affected toe. As blood accumulates, the nail may turn shades of dark red, purple, or black. Some individuals experience a throbbing sensation, particularly after running or extended physical activity. In more severe cases, the nail may loosen or eventually fall off. This discomfort can interfere with daily activities and make it difficult to maintain a regular training routine without proper care.

The primary cause of a black toenail is repetitive stress linked to running mechanics. Wearing ill-fitting shoes, especially those that are too tight or too short, significantly increases pressure on the toes. Activities such as downhill running or sudden stops can force the toes forward, intensifying the impact. Additionally, poor running form and long training sessions without sufficient rest can further contribute to nail damage and irritation.

Several risk factors increase the likelihood of developing this condition, including long-distance running, wearing improper footwear, and inadequate nail maintenance. Preventive strategies include keeping toenails trimmed, wearing properly fitted running shoes, and choosing moisture-wicking socks to reduce friction. Maintaining proper foot alignment and gradually increasing training intensity can also help minimize stress on the toes. Toe issues can be uncomfortable, and often cause difficulty in running. If toe pain persists, it is suggested that you consult a podiatrist for appropriate treatment and prevention guidance.

Toe pain can disrupt your daily activities. If you have any concerns, contact One of our podiatrists of Diagnostic Foot Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.

What Causes Toe Pain?

Most severe toe pain is caused due to a sports injury, trauma from dropping something heavy on the toe, or bumping into something rigid. Other problems can develop over time for various reasons.

Toe pain can be caused by one or more ailments. The most common include:

• Trauma
• Sports injury
• Wearing shoes that are too tight
• Arthritis
• Gout
• Corns and calluses
• Hammertoe
• Bunions
• Blisters
• Ingrown toenails
• Sprains
• Fractures (broken bones)
• Dislocations

When to See a Podiatrist

• Severe pain
• Persistent pain that lasts more than a week
• Signs of infection
• Continued swelling
• Pain that prevents walking

Diagnosis

In many cases the cause of toe pain is obvious, but in others, a podiatrist may want to use more advanced methods to determine the problem. These can range from simple visual inspections and sensation tests to X-rays and MRI scans. Prior medical history, family medical history, and any recent physical traumatic events will all be taken into consideration for a proper diagnosis.

Treatment

Treatments for toe pain and injuries vary and may include shoe inserts, padding, taping, medicines, injections, and in some cases, surgery. If you believe that you have broken a toe, please see a podiatrist as soon as possible.

Wearing shoes that fit properly is essential for maintaining foot health, preventing pain, and supporting daily activity. A well-fitted shoe provides adequate space, stability, and alignment for the foot while allowing natural movement. Shoes should match the shape of the foot and provide proper arch support and cushioning. Wearing ill-fitting footwear, whether too tight or too loose, can lead to discomfort and long-term complications. Choosing the correct shoe size and design is a key step in preventing avoidable foot problems.

Common foot conditions from wearing poorly fitting shoes include blisters, toe pain, and bunions. Shoes that are too loose can lead to instability, friction, and an increased risk of falls. Individuals may also experience heel pain or arch strain when support and cushioning are inadequate. These symptoms can interfere with walking and reduce overall comfort throughout the day.

Several risk factors contribute to improper shoe fit. Many individuals wear the wrong size due to changes in foot shape over time. Feet should be measured regularly to ensure an accurate fit, especially as aging, weight changes, or medical conditions can alter foot size. Proper shoes should grip the heel securely without slipping and allow enough room in the toe box. Selecting footwear designed for a specific sport or activity is also important, as different movements require different types of support and cushioning.

Wearing properly-fitted shoes can prevent many common foot conditions and improve overall comfort. Supportive design, proper sizing, and activity-specific features all contribute to better foot health. Taking the time to choose the right footwear can make a significant difference in daily mobility. If you have foot pain related to wearing shoes that do not fit right,it is suggested that you consult a podiatrist for effective relief tips and guidance on how to choose shoes that fit properly.

Getting the right shoe size is an important part of proper foot health. Seek the assistance of One of our podiatrists from Diagnostic Foot Specialists. Our doctors 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.

Stress fractures are tiny cracks in a bone that develop when repeated force places more stress on the bone than it can repair. They are frequently found in the feet because these bones absorb pressure with every step. A sudden increase in running, jumping, or other high-impact activities can trigger this injury. People who begin a new fitness program, change workout intensity too quickly, or spend long hours on hard surfaces face a greater risk. Shoes that lack proper support can also add extra strain to the feet. Pain usually starts in one specific area and gradually becomes worse with activity. As the injury progresses, discomfort can continue while walking and even during normal daily routines. Swelling and tenderness near the painful spot are also common warning signs.

Because stress fractures can resemble other foot problems, an accurate diagnosis is important. A podiatrist begins with a detailed discussion of your symptoms and a careful examination of the foot. X-rays help identify many stress fractures, although very early injuries are not always visible. In those cases, an MRI, which creates detailed images of bones and soft tissues, can reveal the injury before it appears on an X-ray. Finding the problem early lowers the chance that the crack will become larger or develop into a complete fracture. A prompt diagnosis also helps guide the safest treatment plan and supports a smoother recovery.

Treatment depends on the location of the stress fracture and its severity. A podiatrist can reduce pressure on the injured bone with a walking boot, a stiff-soled shoe, or crutches. Your podiatrist also monitors healing with follow-up visits and imaging, when appropriate. Some fractures heal well with these measures, while others require surgery because of their location or because they are unlikely to heal properly without added support. Early professional care can shorten recovery and help prevent more serious damage. If you have symptoms of a stress fracture, it is suggested that you schedule an appointment with a podiatrist for diagnosis and appropriate treatment.

Stress fractures occur when there is a tiny crack within a bone. To learn more, contact One of our podiatrists from Diagnostic Foot Specialists. Our doctors can provide the care you need to keep you pain free and on your feet.

How Are They Caused?

Stress fractures are the result of repetitive force being placed on the bone. Since the lower leg and feet often carry most of the body’s weight, stress fractures are likely to occur in these areas. If you rush into a new exercise, you are more likely to develop a stress fracture since you are starting too much, too soon.  Pain resulting from stress fractures may go unnoticed at first, however it may start to worsen over time.

Risk Factors

• Gender – They are more commonly found in women compared to men.
• Foot Problems – People with unusual arches in their feet are more likely to develop stress fractures.
• Certain Sports – Dancers, gymnasts, tennis players, runners, and basketball players are more likely to develop stress fractures.
• Lack of Nutrients – A lack of vitamin D and calcium may weaken the bones and make you more prone to stress fractures
• Weak Bones – Osteoporosis can weaken the bones therefore resulting in stress fractures

Stress fractures do not always heal properly, so it is important that you seek help from a podiatrist if you suspect you may have one. Ignoring your stress fracture may cause it to worsen, and you may develop chronic pain as well as additional fractures.

Ballet dancers rely on precise foot biomechanics to perform controlled and graceful movements. The foot is a highly specialized structure made up of interconnected bones that work together to provide stability and flexibility. During dance, the foot must transition between flat positions and elevated positions while maintaining balance. This requires strong coordination between the arch, toes, and supporting muscles. A clear understanding of how these elements function together helps dancers optimize performance and reduce the risk of injury.

The symptoms of poor foot biomechanics in ballet may include pain, fatigue, and instability during movement. Dancers may notice difficulty maintaining balance or achieving proper alignment in positions. The arch may collapse under pressure, or the toes may not distribute weight evenly. These issues can lead to discomfort and increase the likelihood of overuse injuries. Early recognition of these signs allows for corrective strategies that support better movement patterns.

Certain risk factors can affect how the foot performs in ballet. Foot shape, muscle strength, and joint flexibility all play a role. A medium arch provides an effective balance between mobility and support, which is ideal for most dancers. A square foot shape with straight toes helps create even pressure distribution, especially when working in pointe shoes. However, dancers with different foot types can still perform well with proper conditioning and technique. Identifying individual risk factors helps guide personalized care.

The causes of foot strain in ballet are often related to repetitive loading and mechanical imbalance. When the bones and joints do not work together efficiently, stress can build up in certain areas, leading to injury. Preventive measures include strengthening exercises, proper warm up routines, and wearing supportive footwear. Consistent care and technique refinement are essential for long term success in dance. If you have endured a foot or ankle injury while engaged in ballet dancing, it is suggested you consult a podiatrist for an accurate diagnosis and appropriate treatment.

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.
