Corns and calluses are one of the most common reasons people come into the shop — and one of the most preventable. They’re not a skin disease; they’re your skin protecting itself from too much pressure or rubbing. Fix the pressure and you usually fix the problem.
What they actually are
- A callus is a broad patch of thickened, hardened skin — usually on the sole, under the ball of the foot or the heel.
- A corn is smaller and more focused, often with a hard centre, typically on or between the toes where bone sits close to the skin.
Both are the body’s response to repeated friction and pressure. They build up to shield the tissue underneath.
Why they form
Almost always, it comes down to load and rubbing:
- Ill-fitting shoes — too tight, too narrow, or pointed, which squeeze the toes (a classic cause of corns between and on top of the toes).
- High heels, which throw extra pressure onto the ball of the foot.
- Thin, hard soles that don’t absorb shock, so the ball and heel take the hit.
- No socks, or shoes that slip, which increases rubbing — worse when feet sweat.
- Foot shape and mechanics — bony prominences, bunions, or uneven pressure from your gait can concentrate load in one spot (the same loading that drives metatarsalgia).
How the right footwear and insoles help
You can soften and smooth a callus all you like, but if the pressure is still there it comes straight back. The real fix is to relieve and redistribute the load:
- Roomy, well-fitting footwear — a wide, deep toe box so toes aren’t squeezed, soft uppers with no hard seams over pressure points. Our orthopaedic footwear is built around exactly this.
- Cushioned soles that absorb shock instead of passing it to the skin.
- Padded or offloading insoles that spread pressure across the whole foot. For a recurring corn or callus over one stubborn spot, custom orthopaedic insoles can offload that point specifically, so the skin stops being overloaded.
Simple prevention at home
- Wear shoes that fit — width matters as much as length; shop later in the day when feet are slightly larger.
- Wear socks that wick moisture; keep feet dry.
- Moisturise regularly to keep skin supple, and gently file hard skin after a bath — don’t dig at it.
- Never cut corns or calluses yourself with a blade, and be careful with acid “corn caps”, which can burn healthy skin.
If you have diabetes, take corns seriously
This part matters. If you have diabetes or reduced sensation, a corn or callus can hide a sore or ulcer forming underneath — and you may not feel it. Do not cut or use corn caps, and have any corn, callus, crack or colour change checked by a doctor promptly. The right diabetic footwear and offloading are about preventing these pressure points in the first place — see our guide to diabetic foot care. We’re a footwear shop, not wound care.
When to see a doctor
See a doctor or podiatrist if a corn or callus is painful, keeps coming back, looks infected, or if you’re diabetic. For everyone else, sorting out the footwear and pressure is usually what ends the cycle.
