TLDR
- Calluses are patches of hardened, thickened skin that form when the same area of your foot deals with repeated friction or pressure, usually from footwear, activity, or the way you walk.
- Corns are related but different: smaller, cone-shaped areas of hard skin over a bony area, often on or between the toes, and tend to be more painful than calluses.
- Most minor calluses can be softened and managed at home with soaking, gentle exfoliation and daily moisturising.
- Painful, cracked or recurring corns and calluses, and any hard skin on the feet of someone with diabetes or poor circulation, need a podiatrist rather than a pumice stone.
- A podiatrist can safely remove stubborn corns and calluses, then find out whether footwear, foot structure or gait is the underlying cause so the hard skin does not keep coming back.
If you have noticed hard, thickened skin building up on your feet, you are not alone. Corns and calluses are among the most common foot skin conditions podiatrists see, and in most cases they are easily treated once you understand what is causing them. This guide covers what a callus is, how it differs from a corn, why they form, how to treat them at home, and when it is time to see a podiatrist.
What is a Callus?
A callus is an area of skin that thickens in response to repeated friction or pressure. When the same patch of skin is rubbed or compressed repeatedly, skin cells respond by producing extra keratin, building up into hardened, dry patches that are less elastic than the surrounding skin.
It is a protective response, not a disease. Left alone, though, a callus that keeps growing can eventually crack, turning a harmless build-up of dead skin into a painful problem. Calluses tend to be broad, flat and diffuse, most often forming on the sole, the heel, or the outer edge of the foot, wherever pressure lands hardest with each step.
Corns and calluses: what’s the difference?
Corns and calluses are often lumped together, but the difference matters for treatment. A callus is a wide, flat area of thickened skin with no defined edge. A corn is smaller and more concentrated, forming directly over a bony area, usually on top of or between the toes. Hard corns typically sit on the tops or tips of toes, where bone presses against the shoe. Soft corns develop between the toes, where sweat keeps the skin softer and whiter while pressure from the neighbouring toe still drives the corn deeper.
The core of a corn presses on the nerves and tissue beneath it, which is why corns are often more painful than calluses despite being smaller. Slightly swollen, inflamed skin, or a sensation like a small stone underfoot, usually points to a corn rather than a callus.
What causes calluses and corns?
Corns and calluses develop for the same reason: your skin is protecting itself from excessive pressure.
1. Poorly fitting footwear
Tight shoes squeeze the toes and create friction; loose shoes let the foot slide and rub. Wearing high heels or narrow shoes for long periods shifts excess pressure onto the ball of the foot and drives both corns and calluses.
2. Repeated friction from activity
Running, hiking, court sports and everyday walking place repetitive pressure on the same spots, and socks that don’t fit properly add excessive friction.
3. Foot structure and gait
Flat feet, high arches, bunions and hammertoes concentrate bone pressure on specific areas rather than spreading it evenly, a common underlying cause when corns or calluses keep returning despite good home care.
4. Foot hygiene basics
Inadequate drying between the toes, toenails that aren’t trimmed regularly, and walking barefoot on rough surfaces all contribute to thickened skin.
Recognising the underlying cause is the first step towards treatment that lasts, rather than one offering only short-term relief.
Symptoms: is it a callus, a corn, or something else?
Most corns and calluses share the same tell-tale features: thick, hardened skin that feels rough or waxy, a yellow or greyish tone against the surrounding skin, and little sharp pain unless the area has cracked or become infected. Discomfort typically worsens with pressure, such as standing for long periods or wearing tight shoes. Redness, warmth, swelling or a foul smell may indicate infection rather than a straightforward callus, and is worth a prompt visit to a podiatrist.
Home treatment for corns and calluses
Minor calluses respond well to consistent home care. According to the American Orthopaedic Foot & Ankle Society, most corns and calluses can be softened and managed with simple, regular self-care as a first step.
- Soak in warm, soapy water for ten to fifteen minutes a few times a week to soften hardened layers of skin.
- Exfoliate gently with a pumice stone, foot file or emery board once the skin is soft, stopping before it feels tender. Removing too much skin in one go can do more harm than good.
- Moisturise daily with a cream containing urea, lactic acid or salicylic acid (not suitable for everyone, particularly people with diabetes).
- Cushion and redistribute pressure with gel pads, felt padding or toe separators. Lamb’s wool between the toes is a gentle option for soft corns. Toe-socks can also help, especially for protection from corns and blisters during sports or running.
- Address footwear by choosing shoes with a wide toe box that fit properly, wear well-fitted socks, and save high heels for occasional wear.
Local pharmacies stock pumice stones, foot files and cushioning pads, and these home remedies usually work for minor, uncomplicated cases. What they won’t fix is the underlying cause. If the same corn or callus keeps returning in the same spot, that’s a sign something structural needs attention.
When to see a podiatrist
See a podiatrist if:
- The corn or callus is painful, red, swollen or shows signs of infection.
- You have diabetes, poor circulation or another condition that affects healing.
- The area keeps cracking, bleeding or recurring despite home care.
- You can’t tell whether you’re dealing with a corn, callus, wart or another skin condition.
Left untreated, a cracked callus or deep corn can become a doorway for infection, a genuine risk for anyone with diabetes or poor circulation. A podiatrist can debride corns and calluses safely and painlessly, since hardened skin has no nerve supply, without the risk of cutting too deep that comes with home tools.
How Advance Foot Clinic treats corns and calluses
Our podiatrists start with a proper diagnosis, then look beyond the skin itself. A corn or callus is often a symptom of how your foot functions, so treatment usually happens in two steps: safe, painless removal of the built-up skin for immediate relief, followed by working out why it developed, whether that’s footwear, gait, or foot structure.
Where flat feet, high arches or an uneven gait are placing excess pressure on specific areas, custom orthotics can correct the underlying mechanics rather than just treating the symptoms, which is what stops corns and calluses becoming something you keep coming back for.
Preventing corns and calluses
Prevention comes down to reducing friction and pressure before hard skin has a chance to form: choose properly fitting shoes with a roomy toe box, limit how often you wear high heels, keep feet clean and dry (especially between the toes), keep toenails trimmed straight across, moisturise regularly, and pad any area that takes repeated pressure. If minor calluses keep forming in the same spot, it’s worth having your foot structure and gait checked before the problem grows.
FAQs About Calluses
- Are corns and calluses permanent?
No. They can be softened, reduced or removed with the right care, though they may return if the underlying cause isn’t addressed.
Should I cut a corn or callus off myself?
If left untreated, calluses can crack, leading to pain or infection. This is especially risky for people with diabetes or compromised circulation.
