Do you notice thickened or hardened areas of skin forming on your feet, especially beneath the toes or across the balls of your feet? These may be calluses, which are a natural response to repeated pressure or friction. While calluses typically are not painful, they can cause discomfort or irritation when they become overly thick or persist for long periods.
Understanding what causes calluses can help you manage them better, ensuring your feet stay comfortable and free from irritation in your daily activities.
Causes of Foot Calluses
As mentioned earlier, calluses are formed when the skin thickens in response to repeated friction or pressure, acting as a natural protective barrier. While this process is normal, several factors can increase the likelihood of it appearing or becoming more pronounced over time.
Daily routines can have a significant impact on the formation of foot calluses. Walking or standing for long periods places constant stress on weight-bearing areas of the feet. Tight or poorly cushioned shoes increase this pressure, while loose footwear allows rubbing that encourages thickened skin to form.
Active lifestyles can also contribute to callus formation. Activities such as running or playing sports place repeated pressure on specific areas of the feet, increasing friction over time. Following these activities, frequent bathing or showering may strip the skin of its natural moisture, leaving it more vulnerable to thickening and hardening. Without proper foot care to reduce friction and maintain hydration, these factors can accelerate the formation of foot calluses.
Certain health conditions may also increase the likelihood of calluses forming. Chronic skin issues such as psoriasis and eczema, hormonal imbalances caused by thyroid dysfunction, and the natural ageing process can leave the skin drier and less resistant to pressure. Medications that contribute to dryness may further weaken the skin’s defences, making it more susceptible to thickening over time.
For individuals managing diabetes, calluses require special attention due to the potential for more serious outcomes. Neuropathy, which diminishes sensation in the feet, often makes it difficult to notice thickened skin as it forms. If left unaddressed, these hardened areas may crack, opening the door to diabetic foot ulcers. Such wounds carry a heightened risk of infection and, in severe cases, may lead to complications requiring urgent medical care.
Symptoms of Foot Calluses
Calluses typically appear as rough, dry patches of thickened skin that may take on a greyish or yellowish tone. These areas are most found on the soles of the feet, particularly in weight-bearing regions such as the ball of the foot or heel. Unlike the surrounding skin, calluses are less sensitive to touch due to their hardened layers.
While calluses are often asymptomatic in their early stages, persistent pressure or friction can irritate them over time, leading to tenderness or discomfort during activities like walking or standing. As they grow thicker, these hardened areas can become painful. In more severe cases, cracks or fissures may form within the callus, causing significant pain and increasing the risk of infection if left untreated.
Types of Foot Calluses
Foot calluses can vary in size, location, and structure, depending on the forces that cause them. Understanding these variations helps identify specific triggers and manage discomfort.
- Plantar Calluses: These are the most common, forming on weight-bearing areas of the soles, such as the ball of the foot or heel. These calluses are typically flat, broad, and hard, spreading outward due to repeated pressure and friction from walking or standing.
- Pinch Calluses: These are formed along the edges of the toes, where the skin is pinched or compressed by tight shoes. Often found on the little toe or the edge of the big toe, they are hard, localised, and can be painful due to continuous pressure.
Within these categories, additional variations can occur. A discrete nucleated callus is a localised, painful lesion distinguished by the presence of a central keratin plug. This plug is a dense accumulation of keratin, a tough protein that the skin produces in response to repeated pressure or friction. The hardened plug can press into underlying tissue, causing discomfort or pain. Due to its appearance, it can sometimes be confused with a plantar wart, though keratin plugs are not caused by a virus and lack the characteristic black dots associated with warts. In contrast, a diffuse-shearing callus appears as a larger lesion, typically measuring more than one centimetre across. Unlike the discrete nucleated callus, it does not contain a keratin plug.
In some cases, calluses may form inward instead of outward, creating what is known as a plugged callus. With its dense, hardened core pressing into the foot, this type of callus can lead to significant discomfort, especially during prolonged activity. These inward-growing calluses further illustrate the diverse ways in which repeated pressure can affect the skin, highlighting the need for targeted care based on their specific characteristics.
Stages of Foot Calluses
As foot calluses form and persist, they progress through distinct stages based on the level of thickening and structural changes. While the type determines its location, the stage reflects its severity and impact on comfort.
- Stage 1: At this stage, the callus is minimally thickened, appearing as a light layer of hardened skin. The area may feel slightly rough or dry but remains painless and flexible.
- Stage 2: The callus becomes more pronounced, with greater thickening and a firmer texture. Discomfort may arise during prolonged activity, particularly in areas under frequent pressure or friction.
- Stage 3: The callus shows significant structural changes, forming concentric keratin plugs within the thickened skin. These plugs can cause localised pain, especially when pressure is applied directly.
- Stage 4: In its most severe stage, the callus develops deeper layers of hardened tissue and density changes. Fissures or cracks may form, leading to pain and an increased risk of infection. These calluses can affect mobility and require professional care.
Managing and Preventing Foot Calluses
Proper care and preventative measures can help manage and reduce the risk of foot calluses. Here are some strategies:
- Wear Proper Shoes: Choose comfortable, well-cushioned shoes with a wide toe box (2E or 4E width) to reduce pressure on the feet. Avoid high heels and shoes with narrow designs that pinch or compress the toes.
- Wear Socks: Use thick, cushioned socks that fit snugly without bunching, as this minimises friction and reduces the risk of calluses.
- Use Orthotics: Add a pair of insoles to redistribute pressure across your feet. For personalised support, consult a podiatrist for custom-made ones.
- Exfoliate: Gently remove dead skin with a pumice stone or foot file, ideally after bathing when the skin is softer. This helps prevent hardened areas from building up.
- Moisturise: Keep your skin hydrated by applying a moisturising cream or lotion regularly. This helps maintain softness and prevents thickening.
- Soaking: Soak your feet in warm water. This softens the skin, making it easier to care for calluses.
- Use Padding: Apply cushioning pads to areas prone to friction to reduce pressure and protect the skin.
- Adjust Your Posture: Improving your posture can reduce muscle tension and uneven pressure on the feet, helping to prevent calluses in high-pressure areas.
If calluses are causing significant discomfort or if you have diabetes or poor circulation, it’s important to consult a podiatrist for professional care.

Frequently Asked Questions About Foot Calluses
A foot callus is a thickened, hardened patch of skin that forms in response to repeated pressure or friction. Commonly found on the soles, ball of the foot, or heel, calluses act as a protective barrier but can become uncomfortable if they grow too thick. Typically dry and rough in texture, they are less sensitive than surrounding skin. Regular care helps manage calluses and prevent further discomfort.
To get rid of foot calluses, begin by soaking your feet in warm water to soften the hardened skin. Use a pumice stone or foot file to gently remove the thickened area. Moisturise daily to keep your skin hydrated and supple, which helps prevent calluses from returning. If calluses persist, cause discomfort, or are painful, consult a podiatrist for professional debridement and advice tailored to your foot care needs.
Foot calluses and foot corns share similarities but are not the same. Both result from pressure or friction, but they differ in appearance and location. Calluses are larger, rough, and flat, typically forming on weight-bearing areas like the soles. Corns are smaller, more defined, and may have a painful central core. Corns usually appear on the toes or bony areas, where pressure is more localised.
Debridement of a foot callus is the process of carefully removing thickened, hardened layers of skin that have formed due to repeated pressure or friction. This is typically performed by a podiatrist using precise tools to reduce the callus without causing damage to the surrounding healthy skin of the foot. Debridement helps alleviate discomfort, improve foot function, and prevent further complications, such as cracks or infections, particularly in advanced or painful calluses.
Orthotics can play a key role in managing and preventing foot calluses. These custom-made insoles help redistribute pressure, reducing strain on areas of the feet that experience excessive friction. By addressing underlying structural imbalances, orthotics can alleviate discomfort caused by existing calluses and help prevent them from returning. Consult a podiatrist to make a pair that is tailored to your feet.
