Blisters might be the bane of many athletes and weekend warriors alike, but they’re not just a sports injury—these pesky little skin irritations can happen to just about anyone. I’ve seen all sorts in my clinic, from seasoned runners clocking up kilometres in Melbourne’s unpredictable weather to new mums juggling prams and the odd blister from those “just perfect” shoes that weren’t quite so perfect after all.
It’s your body’s way of saying, “Hey, slow down! This spot is getting a battering.” Think of it as a natural band-aid forming right on your skin. While most blisters hold this clear fluid, sometimes they contain a bit of blood if small vessels burst (blood blisters), or pus if infection sneaks in — which, believe me, you want to avoid.
In my experience, recognising this process helps patients feel a little less anxious when a blister shows up after a long day out on the footy field or a bushwalk in the Dandenong Ranges. Rather than panic, understanding blisters encourages better care and patience.
Common Causes of Blisters in Everyday Life and Sport
Blisters rarely just pop up out of the blue — usually there’s a reason, and it’s often linked to how we move, what we wear, or sometimes even health issues.
1. Sports and Physical Activities
It’s no surprise that sports and exercise are top offenders when it comes to blister trouble. Take running, for example — pounding the pavement in Melbourne’s often damp conditions can create the perfect storm of friction and moisture. I’ve treated many runners who’ve battled blisters on their heels, toes, or the balls of their feet, especially after a long training session or that first foray into a half marathon.
Cyclists, too, can get blisters in less obvious spots, like the inner thighs or even their hands from gripping the handlebars. Rowers and other sports that involve repetitive movements also get their fair share. If you’ve ever worn the wrong gloves or socks for your sport, you’ll know exactly what I mean!
2. Poorly Fitting Footwear
This one’s a classic — the new shoe you just couldn’t resist, only to find out it’s pinching in all the wrong places. Many Australians don’t realise that foot size and shape can change with age, pregnancy, or weight fluctuations, meaning shoes that once fit like a glove may start rubbing painfully after a while.
In Melbourne’s climate, where you might slip into a pair of boots for winter and thongs (flip-flops) in summer, switching between such extremes without giving your feet a chance to adjust can spell trouble. Leather shoes that haven’t been broken in properly, or cheaper synthetics that don’t stretch, can also create hotspots ripe for blister formation.
3. Burns
Blisters don’t only come from friction — burns are another culprit. Think sunburn after a day at Bondi or a poorly handled hot cup of tea at home. Frostbite is rare down here but can happen during bushwalks in alpine areas in winter.
The skin responds to these injuries by creating blisters to protect the deeper layers, but the damage to the skin’s surface can be significant, so taking care is crucial.
4. Medical Conditions
Sometimes blisters signal something more than just a surface injury. Conditions like chickenpox or hand, foot, and mouth disease come with blistery rashes that need attention. Even herpes simplex can cause blisters around the mouth or other sensitive areas.
If you’ve noticed unusual blistering without any obvious cause, it’s worth getting it checked — I’ve seen a few cases where early diagnosis of skin conditions made a huge difference in treatment.
5. Allergic Reactions
Blisters can also be the skin’s protest against an allergen. Poison ivy isn’t common here in Australia, but we do have similar offenders like certain plants (e.g., stinging nettles), metals like nickel in jewellery, or harsh chemicals in some laundry detergents and cosmetics.
Knowing what triggers these reactions and avoiding them is key. For example, I once treated a patient who developed blisters from a new pair of earrings made from cheap metal, which cleared up quickly once they switched to hypoallergenic options.
How to Prevent Blisters — Practical Tips You Can Use Today
Blisters might be a natural defence, but there’s no reason to put yourself through the pain and hassle if you can help it. Over the years, I’ve seen blister prevention turn from a bit of guesswork to a science — and the good news is, a few simple steps can make all the difference.
Prevention Checklist: Keep Your Feet Happy and Blister-Free
| Prevention Tip | Why It Matters | Aussie-Specific Advice |
| Choose the Right Footwear | Reduces pressure and friction points | Get your feet measured professionally; sizes can change with age or pregnancy. Local stores like The Athlete’s Foot offer fitting services. |
| Wear Moisture-Wicking Socks | Keeps feet dry, lowering friction risk | Look for socks made from merino wool or synthetics — perfect for Melbourne’s changeable weather. Avoid cotton socks, which hold moisture. |
| Break In New Shoes Gradually | Helps shoes mould to your feet without harsh rubbing | Start wearing new shoes for short periods at home, then slowly increase. Melbourne’s unpredictable weather means you can’t always rely on a quick dry! |
| Use Protective Pads or Bandages | Shields hotspots from direct friction | Moleskin pads or hydrocolloid bandages work wonders on heels or toes. Available at local chemists and podiatry clinics. |
| Keep Feet Dry | Damp skin is more fragile and prone to blisters | Use foot powders or antiperspirants designed for feet. Change socks if you’re out all day in humid conditions, like during a Sydney summer. |
1. Choose the Right Footwear
It’s a no-brainer but easy to overlook. Your footwear is the frontline in preventing blisters. A good fit means your foot stays put without excessive sliding or pinching. Here in Australia, where you might dash from a casual stroll on the beach to a long day at work, your shoe choice needs to be versatile and comfortable.
Foot sizes and shapes change over time — I often see patients surprised that their “usual size” shoes just aren’t working anymore. Getting professionally measured every couple of years at specialist stores is well worth it.
2. Wear Moisture-Wicking Socks
Sweaty feet are blister magnets. Socks that wick moisture away, like those made from merino wool or quality synthetic fibres, keep your skin dry and happy. Cotton socks, despite being comfy, tend to trap moisture and make your skin soft and vulnerable.
If you’re doing a big day on your feet — say, walking the Bondi to Coogee coastal trail — pack a spare pair of socks. It’s a small thing that makes a big difference.
3. Break In New Shoes Gradually
I always tell patients, don’t expect to wear new boots or runners for a full day straight out of the box. Give your feet time to get used to them — wear them for short walks around the block or at home first.
This is especially important with leather shoes or hiking boots that are less forgiving than soft sneakers. Over time, the shoe moulds to your foot shape, reducing rubbing spots.
4. Use Protective Pads or Bandages
If you know your heels or toes are prone to rubbing, pre-empt the blister by applying moleskin pads or silicone guards before heading out. Hydrocolloid dressings, which you might know from sports stores or chemists, are excellent as they cushion and also promote healing if a blister starts to form.
I had a patient who swore by these pads during the Melbourne Marathon — she said they were a real game-changer.
5. Keep Feet Dry
It sounds simple but keeping your feet dry is key. Use foot powders or antiperspirant sprays, especially during warmer months or if you’re prone to sweating. Change your socks mid-day if you can — it’s a small effort that pays off.
Also, let your shoes air out after use. Melbourne’s damp winters can leave shoes clammy, so drying them overnight near a heater or in a well-ventilated area helps keep moisture at bay.

Treating Blisters Properly — What Works and What Doesn’t
Even with all the prevention in the world, blisters can still pop up. When they do, how you handle them can make all the difference between a quick recovery and a nasty infection that slows you down.
1. Don’t Pop It (Unless You Really Need To)
One of the biggest mistakes I see is patients reaching straight for a pin or needle, eager to burst their blister. It’s tempting, especially when the blister is large or painful, but your body’s fluid-filled sac is there for a reason — it acts as a natural barrier, protecting the delicate skin underneath from germs and further damage.
If the blister pops on its own, don’t panic. Clean the area gently with mild soap and water, pat it dry, and cover it with a sterile dressing. If you must drain a large blister because it’s causing too much pain or getting in the way, do it carefully: sterilise a needle with rubbing alcohol, puncture the edge, and gently squeeze out the fluid. Then clean and cover the site properly.
2. Clean and Protect
Whether your blister popped naturally or you drained it, cleanliness is key. I always recommend washing with mild soap and warm water, then drying thoroughly. Keeping the blister covered with a breathable, sterile bandage protects it from dirt and rubbing.
For extra protection, a thin layer of antibiotic ointment helps prevent infection — you can pick up these creams from your local Chemist Warehouse or pharmacy.
3. Avoid Further Friction
Nothing stalls blister healing faster than ongoing rubbing and pressure. If the blister’s on your foot, try to give it a rest. Swap your shoes for a softer, more comfortable pair, or use cushioned insoles or orthotic inserts if you have them. I often fit patients with custom orthotics that help offload pressure from blister-prone spots — a game changer if you’re regularly on your feet in Melbourne’s unpredictable weather.
For blisters on hands — say, from gardening or rowing — wearing gloves or wrapping the area with protective tape can stop things getting worse.
4. Know When to See a Podiatrist
Some blisters just won’t quit, or worse, start showing signs of infection. If you notice yellow pus, redness spreading beyond the blister, increasing warmth, swelling, or if the pain is severe and worsening, it’s time to get professional help. I’ve treated many patients whose blisters became infected because they delayed care, and it can lead to more serious complications like cellulitis.
At Well Heeled Podiatry, we can drain stubborn or painful blisters safely and provide tailored advice for your specific needs. Sometimes a blister is a sign of an underlying foot condition — such as abnormal biomechanics or persistent pressure points — and addressing those is the best way to prevent future issues.
Real-Life Scenario:
I had a patient who’d just started training for the Great Ocean Road Marathon. She came in with a massive blister on her heel that she’d tried to pop at home. It got infected and was incredibly painful. After draining it safely and fitting her with custom orthotics to offload the pressure, she healed well and was back on the road within weeks — no more blisters holding her back.
Why Blister Care Matters — Avoiding Complications and Staying Active
Blisters might seem like a small nuisance — a mere inconvenience — but they can quickly snowball into something more serious if left untreated. From infection to prolonged pain that slows your daily routine or puts your favourite sport on hold, blisters have a knack for turning up when you least want them.
The good news? With a bit of care and attention, you can keep blisters at bay or help them heal quickly. This means less downtime, fewer worries, and more time spent doing what you love — whether that’s kicking around a footy on the weekend, walking barefoot along a Queensland beach, or simply chasing after the kids without a limp.
A Few Last Pearls From My Clinic
- Listen to your feet. If you feel hot spots or rubbing early on, don’t ignore them. Apply protection or switch your shoes before it turns into a blister.
- Keep your skin healthy and dry. This simple step prevents a heap of trouble — especially in humid places like Brisbane or after a wet Melbourne day.
- Don’t tough it out. It’s tempting to push through the pain, but giving your feet a break can save you weeks of discomfort.
- See a podiatrist when needed. There’s no harm in getting professional advice. Sometimes a blister is a sign of an underlying issue that needs fixing. At Well Heeled Podiatry, we’re here to help get your feet feeling their best.
I often remind patients about our Aussie love of outdoor adventures — from hiking the Blue Mountains to surfing in Byron Bay. The common thread? Feet that can keep up. Taking care of blisters isn’t just about avoiding pain; it’s about staying active, enjoying life, and making every step count.
Blisters are your body’s way of waving a red flag, saying, “Slow down, you’re stressing this spot too much.” Treat them with respect, prevent where you can, and seek help when necessary. Your feet carry you through every part of your day — give them the care they deserve, and they’ll reward you with every step you take.
Frequently Asked Questions
What Causes Blisters?
Blisters are small pockets of fluid that form between the layers of skin due to friction, heat, or pressure. The most common causes are repetitive rubbing from shoes, tight socks, or vigorous physical activity like running or hiking. However, blisters can also be caused by burns, infections, allergic reactions, or even certain skin conditions. While often seen in sports, blisters can develop from everyday activities if friction is applied to the skin over time.
Are Blisters Only A Concern For Athletes?
No, blisters are not exclusive to athletes. While sports-related blisters are common due to physical activity, anyone can develop a blister. Activities like walking long distances, wearing new or ill-fitting shoes, or even manual labour can result in blisters. Additionally, people with certain medical conditions, like diabetes, may be at greater risk of developing blisters from even minor friction or trauma, and these can sometimes lead to complications if not properly managed.
Can Blisters Lead To Infections?
Yes, blisters can become infected if the protective skin covering the blister is broken. When the fluid is exposed to bacteria, it can lead to an infection, causing increased redness, swelling, pain, or pus. Infected blisters may require medical attention, especially if you have underlying conditions such as diabetes, which can make infections more dangerous. It’s important not to pop or burst blisters at home to avoid introducing bacteria and to allow the blister to heal naturally.
How Can I Treat And Prevent Blisters?
The best way to treat a blister is to protect it while it heals. Keep the area clean and cover it with a sterile bandage or blister pad. If the blister is large or painful, you may choose to drain it carefully with a sterile needle, but it’s best to leave it intact if possible. To prevent blisters, wear shoes that fit properly and avoid activities that cause repetitive friction. Socks made of moisture-wicking materials can also help reduce the risk of blisters. Regular foot care and checking for signs of irritation can also help avoid them from developing.
What Should I Do If A Blister Doesn’t Heal Or Keeps Recurring?
If a blister doesn’t heal within a few days or keeps recurring in the same spot, it may indicate an underlying issue, such as improper footwear, friction from a specific activity, or a skin condition. In such cases, it’s important to see a healthcare professional or podiatrist. Persistent or recurring blisters can also be a sign of infection, or in some cases, conditions like pressure ulcers or calluses that require targeted treatment.
