Causes of Foot Corn Callus

Friction and pressure on the skin

One of the primary causes of foot corn callus is friction and pressure on the skin. This occurs when there is constant rubbing or irritation against the skin, typically caused by ill-fitting footwear or repetitive movements. The friction and pressure lead to thickened and hardened skin, resulting in the formation of corns or calluses.

Ill-fitting footwear

Wearing shoes that do not fit properly can contribute to the development of foot corn callus. Tight shoes can cause excessive pressure on certain areas of the feet, leading to the formation of corns or calluses. On the other hand, loose shoes can create friction and rubbing, which can also contribute to the development of corns or calluses.

Overuse and repetitive stress

Engaging in activities that put excessive stress on the feet or involve repetitive movements can lead to foot corn callus. This is common in individuals who participate in high-impact sports, run long distances, or engage in activities that require prolonged standing or walking.

Abnormal foot structure

Individuals with abnormal foot structures, such as high arches or flat feet, are more prone to developing foot corn callus. The abnormal foot structure can cause uneven distribution of weight and increased pressure on certain areas of the feet, leading to the formation of corns or calluses.

Foot deformities

Foot deformities, such as bunions or hammertoes, can contribute to the development of foot corn callus. These deformities can cause pressure and friction on specific areas of the feet, leading to the formation of corns or calluses.

Age-related factors

As we age, the skin tends to become thinner and less elastic. This makes older individuals more susceptible to developing foot corn callus. Age-related factors, such as decreased fat padding in the feet and reduced blood circulation, can also contribute to the formation of corns or calluses.

Dry skin and lack of moisture

Dry skin and lack of moisture can make the feet more prone to developing foot corn callus. When the skin is dry, it becomes less flexible and more susceptible to friction and pressure. Regular moisturizing and maintaining proper foot hygiene can help prevent the formation of corns or calluses.

Occupational factors

Certain occupations that require prolonged standing, walking, or wearing restrictive footwear can increase the risk of developing foot corn callus. People in professions such as healthcare, retail, and construction are more prone to foot corn callus due to the nature of their work.

Medical conditions

There are several medical conditions that can contribute to the development of foot corn callus. Conditions such as diabetes, peripheral neuropathy, and rheumatoid arthritis can affect the nerves and blood circulation in the feet, increasing the risk of developing corns or calluses.

Genetic predisposition

Some individuals may have a genetic predisposition to developing foot corn callus. Certain genetic factors can make the skin more prone to friction and pressure, increasing the likelihood of developing corns or calluses.

Symptoms of Foot Corn Callus

Thickened, hardened skin

One of the most common symptoms of foot corn callus is the presence of thickened and hardened skin. Corns or calluses appear as areas of thickened skin that may feel rough or tough to the touch.

Localized pain and tenderness

Foot corn callus can cause localized pain and tenderness in the affected area. The pressure and friction on the skin can lead to discomfort, especially when walking or putting weight on the affected foot.

Visible corns or calluses

In some cases, corns or calluses may be visible on the surface of the skin. Corns typically have a hard, raised center surrounded by inflamed skin, while calluses are larger, flattened areas of thickened skin.

Skin discoloration

Foot corn callus can cause changes in skin color in the affected area. This can range from mild redness to darker or discolored patches of skin.

Changes in foot shape

Corns or calluses can cause changes in the shape of the foot. Depending on the location and severity of the corn or callus, the affected area may appear swollen or distorted.

Difficulty walking or standing

Foot corn callus can make it difficult to walk or stand for prolonged periods. The pain and discomfort associated with corns or calluses can affect mobility and limit daily activities.
