If you’re like many Aussies I see in clinic, foot problems can be a real pain in the you-know-what — especially when you’re trying to figure out if that annoying lump is a corn or a plantar wart. Both can cause a fair bit of discomfort, but they come from very different culprits and need different fixes.
I remember one patient who came in after a few weeks of hobbling around Melbourne’s chilly streets, worried about a sharp lump under her foot. Was it a corn from those new boots she’d been breaking in, or was it a stubborn wart? Let’s clear up that confusion, so you know what you’re dealing with and how to sort it.
Quick heads-up: corns and warts both cause pain but they’re as different as chalk and cheese.
- Foot corns usually pop up where your shoe rubs or where your foot takes the brunt of your weight. They’re hardened, thickened patches of skin, a bit like your foot’s way of putting on a tough coat to protect itself.
- Plantar warts are caused by the human papillomavirus (HPV), a sneaky virus that loves to hang out in warm, moist spots — think public pools and gym changerooms around Australia’s humid summers.
Corns respond well to pressure relief — think comfy shoes, padding, or a careful trim by your podiatrist. Warts, on the other hand, are trickier beasts, often needing treatments like freezing (cryotherapy) or acid peels to kick the virus to the curb.
If you find your DIY efforts aren’t cutting it, or if pain and swelling creep in, don’t muck about — get yourself to a podiatrist. Proper foot care and early intervention are key to keeping you up and about, enjoying everything from barefoot beach walks on the Mornington Peninsula to weekend hikes in the Dandenongs.
Key Differences Between Foot Corns and Plantar Warts
When you’re standing in the shoe aisle at your local shopping centre or chatting with mates at the footy, it’s easy to get foot corns and plantar warts mixed up. But they’re as different as a sunny day at Bondi and a rainy one in Tasmania — and knowing how to spot the difference can save you plenty of grief.
What Causes Them?
Corns are all about physical pressure and friction. Usually, they’re caused by tight or poorly fitting shoes that rub your skin the wrong way, or even from an unusual walking style. They’re your body’s way of saying, “Oi, slow down — I’m getting rubbed raw here!” The skin thickens to protect itself, forming a hard lump in the exact spot of the irritation.
Plantar warts, on the other hand, are caused by the human papillomavirus (HPV). This nasty bug sneaks in through tiny breaks in your skin, usually on the soles of your feet. Because the virus is infectious, warts can spread from one foot to another, or even to other people — so it pays to keep an eye on hygiene, especially if you’re a regular at the local pool or gym.
What Do They Look and Feel Like?
Corns usually have a well-defined hard core, with skin around them sometimes red or inflamed. They’re like small, tough little islands of skin, often painful when you press on them. You can usually feel exactly where they are.
Plantar warts are more irregular in shape and texture — often rough and grainy, sometimes flat or raised like little cauliflowers. That telltale black dot pattern (clotted blood vessels) sets them apart from corns. And because they grow inward, warts can feel like you’re stepping on a pebble or a thorn.
How They Behave
Corns only form where there’s pressure and friction — they’re localised and won’t spread by themselves. They’re non-infectious, so no worries about passing them on.
Warts, however, can spread across your feet or to other people. That’s why you’ll often see “no barefoot” signs around public pools and gyms here in Australia. The virus thrives in warm, moist environments — perfect for our humid coastal climates in places like Brisbane or Cairns.
Treatment Differences
Because corns are caused by physical stress, treatment focuses on reducing that pressure. That means good-fitting shoes, using padding, or sometimes a podiatrist trimming down the tough skin.
Warts need antiviral treatments. Over-the-counter options like salicylic acid slowly peel them away. For stubborn cases, professional treatments like cryotherapy or laser therapy get the job done.
Treatment Options for Foot Corns and Plantar Warts
Let’s get down to brass tacks — how do you get rid of these pesky foot problems? Knowing the cause makes all the difference in treatment.
Tackling Foot Corns
Corns are essentially a pressure problem, so the first port of call is to ease that pressure. Here in Australia, with our love of outdoor life and walking on everything from sandy beaches to hard pavements, choosing the right shoe is a game-changer.
Footwear: You want shoes that fit well, have plenty of toe room, and offer cushioning for the soles. Avoid tight or narrow shoes that squash your toes or rub against the skin. This is especially important for people who spend long hours on their feet, like tradies or nurses working shifts in Melbourne’s unpredictable weather.
Padding and Protection: Using corn pads or moleskin (those little adhesive cushions you can pick up at your local chemist or podiatrist’s clinic) helps shield the corn from further friction. It’s like putting a buffer between your foot and the shoe.
Professional Trimming: Sometimes corns get stubborn and thick. When I see patients with painful corns, I carefully trim the excess hardened skin — but it’s important this is done safely and hygienically to avoid infection.
Orthotics: If there’s an underlying issue like an abnormal gait or foot shape causing uneven pressure, custom orthotics can make a world of difference. I often create bespoke inserts here at Well Heeled Podiatry tailored to redistribute pressure and stop corns coming back.
Managing Plantar Warts
Warts need a different approach since they’re viral. The virus hides deep beneath thick skin, making treatment tricky.
Salicylic Acid: This is the most common over-the-counter treatment and works by gradually softening the wart so it can be scraped away. It’s a slow burner, so patience is key.
Cryotherapy: This treatment freezes the wart with liquid nitrogen and is usually done by a podiatrist or dermatologist. It can be a bit uncomfortable but is effective, especially for tougher warts. Multiple sessions are often needed.
Laser Therapy and Immune Boosters: For stubborn warts, laser treatment zaps the wart tissue, while some topical treatments help your immune system fight the virus. These options are usually available through specialist clinics.
When to See a Podiatrist
Many Aussies try home remedies first, but it’s wise to see a podiatrist if:
- Your corn or wart is painful, growing, or changing colour.
- You have diabetes, peripheral neuropathy, or poor circulation — as these conditions raise the stakes for infections and complications.
- Over-the-counter treatments aren’t working after several weeks.
- You’re unsure whether you have a corn or a wart — a professional diagnosis can save you time and discomfort.
In my practice, I regularly help patients with custom solutions — whether that’s safely removing corns, managing warts, or fitting orthotics to prevent recurrence. Especially with Melbourne’s mix of climate and active lifestyle, foot health deserves top priority.
Prevention Strategies for Foot Corns and Plantar Warts
Prevention is always better than cure — and nowhere is that more true than when it comes to keeping your feet happy and healthy. Both foot corns and plantar warts benefit from good foot care, but because they’re caused by different things, the prevention strategies don’t always overlap.
How to Stop Corns in Their Tracks
Corns are basically caused by your foot getting rubbed the wrong way — literally! So, the best way to avoid them is to reduce pressure and friction.
Choose the Right Shoes: It might sound obvious, but wearing shoes that fit properly is a game-changer. In Australia, our footwear choices vary a lot — from sandals in summer to boots in winter — but the key is always to make sure there’s enough wiggle room for your toes, and the shoe doesn’t pinch or rub.
Watch Your Socks: Thick, cushioned socks can reduce friction, especially when you’re out on a long bushwalk or a day at the footy. Cotton blends that wick moisture away help keep feet dry and reduce skin breakdown.
Use Padding: If you’re prone to corns or just want a bit of extra protection during a big day on your feet, corn pads or moleskin can take the edge off pressure spots.
Mind Your Feet: Regularly inspect your feet — especially if you’re diabetic or have reduced sensation — and moisturise daily to keep skin supple. Dry, cracked skin is a magnet for problems.
Keeping Plantar Warts at Bay
Since plantar warts are caused by a virus, prevention is a bit more about hygiene and environment than footwear alone.
Avoid Bare Feet in Damp Public Areas: Whether it’s the local pool, gym changerooms, or beach showers, HPV loves warm, moist environments. Wearing thongs or slip-on sandals in these spots can save you a world of pain later.
Keep Feet Dry: Change socks regularly and use talcum powder or foot sprays to keep moisture down — especially important in our humid Aussie summers or after a big day of hiking in the Blue Mountains or the Grampians.
Don’t Share Footwear or Towels: Viruses like HPV can hitch a ride on shared items, so keep your gear to yourself.
Boost Your Immune System: A healthy lifestyle goes a long way — good diet, plenty of water, and enough rest all help your body fight off infections, including warts.

Long-Term Management and Care for Foot Corns and Plantar Warts
Looking after your feet isn’t just about fixing problems when they crop up — it’s about keeping them in top shape for the long haul. Whether you’ve battled foot corns or plantar warts before, a good foot care routine will help stop them coming back and keep your feet ready for whatever Aussie adventures you’ve got planned.
Keep an Eye on Your Feet
Make it a habit to give your feet a once-over daily — especially if you spend heaps of time on your feet or have health conditions like diabetes or poor circulation. Check for any signs of pressure spots, lumps, or anything unusual. Early detection means quicker treatment and less hassle down the track.
Moisturise and Exfoliate
Dry, cracked skin is a common invite for foot problems, so keep your feet moisturised daily. I often recommend a good-quality foot cream — and if you’re keen on a natural Aussie twist, look for ones with native ingredients like tea tree oil, which also has antimicrobial properties.
Exfoliating gently once or twice a week helps slough off thickened skin before corns can form. But be careful — don’t overdo it or use harsh tools that can damage skin.
Regular Visits to Your Podiatrist
Even if your feet feel fine, popping in for a check-up once or twice a year can make all the difference. A podiatrist can spot early signs of trouble, assess your foot mechanics, and help tailor a plan — including custom orthotics or shoe advice — to keep you walking pain-free.
For those of us who love the outdoors — whether that’s a stroll on Bondi Beach or a hike in the Grampians — healthy feet make all the difference.
Keep Your Feet in Top Shape
Foot corns and plantar warts might seem like small issues, but they can cause big discomfort if left unchecked. Corns come from pressure and friction — often your shoe’s way of giving you a not-so-subtle hint to switch them out. Plantar warts are caused by a contagious virus that thrives in damp, shared spaces.
Knowing how to spot the difference and treat each properly means you’ll get back on your feet quicker, pain-free, and ready to enjoy all the things we love about life down under — from barefoot beach days on the Mornington Peninsula to weekend footy matches at the local oval.
If you’re struggling with either, don’t hesitate to see a podiatrist. Professional care not only treats the problem but helps stop it coming back. After all, your feet are your foundation — treat them right, and they’ll carry you through many happy, healthy steps ahead.
Frequently Asked Questions
What Causes Foot Corns And Plantar Warts?
Foot corns are produced by pressure and friction from poorly fitting shoes or an irregular walking pattern that stresses particular foot areas. In contrast, plantar warts are formed by HPV infection through small incisions or cracks on the sole.
How Can I Tell If I Have A Foot Corn Or A Plantar Wart?
Foot corns usually have a hard centre and may be surrounded by inflamed skin, feeling firm to the touch. They form on toe tops and sides due to pressure. Cauliflower-shaped plantar warts are gritty and may include black pinpoints (clotted blood vessels). They usually occur on the foot soles, where pressure is greatest.
Are Plantar Warts Contagious, But Are Foot Corns Not?
It’s correct. Plantar warts are infectious and can spread through direct contact with the wart or contaminated surfaces like public showers or pool floors. Foot corns are formed by the skin’s reaction to pressure, not viruses.
What Are The Best Treatment Options For Foot Corns And Plantar Warts?
Improved shoe fit and protective cushions can reduce foot corn pressure. Corns can be treated with salicylic acid or removed by a podiatrist. Plantar warts can be treated with over-the-counter salicylic acid, cryotherapy, or medical laser therapy.
Can Foot Corns And Plantar Warts Be Prevented?
Yes, both are preventable. Foot corns can be avoided with well-fitted shoes and good foot cleanliness. Avoiding barefoot contact with contaminated surfaces, especially in public spaces like gyms or swimming pools, keeping feet clean and dry, and utilising shower shoes in communal bathing facilities help prevent plantar warts.
