Flat Feet in Adults: When Do Fallen Arches Actually Need Treatment?

Flat feet in adults don’t always need treatment. Many people live comfortably with fallen arches their entire lives. You only need intervention if they’re causing pain, affecting your mobility, or changing how you walk.

Here’s the Thing Most People Get Wrong About Flat Feet

Walk into any crowded room in Australia and look down. Roughly 20-30% of adults have flat feet. Most of them are going about their day without a second thought about their arches. The confusion starts when someone notices their feet look different or a well-meaning friend says “you should get that checked.”

The truth is, having flat feet isn’t automatically a problem. What matters is whether they’re causing issues in your daily life. Some people develop flat feet gradually as adults and never experience discomfort. Others find themselves dealing with pain that radiates up their legs, making a trip to the shops feel exhausting.

Why Do Some Adults Suddenly Develop Flat Feet?

You might have had perfectly normal arches your whole life, then noticed them dropping in your 40s or 50s. This isn’t unusual. Adult-acquired flat feet typically happen when the posterior tibial tendon, which supports your arch, weakens or becomes inflamed over time.

Several factors can trigger this change:

• Weight gain that puts extra stress on the supporting structures of your feet
• Ageing and the natural wear and tear on tendons and ligaments
• Pregnancy, which releases hormones that loosen ligaments throughout your body
• Diabetes or high blood pressure, which can affect circulation and healing
• Previous injuries to your foot or ankle that never quite healed properly
• Inflammatory conditions like rheumatoid arthritis that affect joints and connective tissue

Sometimes flat feet are simply inherited. If your parents had them, there’s a good chance you will too. This type tends to be less problematic because your body has adapted to this foot structure from childhood.

What Does It Actually Feel Like?

Not everyone with flat feet experiences symptoms, but when they do appear, they’re hard to ignore. The discomfort usually starts gradually rather than all at once.

You might notice pain along the inside of your ankle or foot, especially after standing for long periods. Some people describe a tired, achy feeling that gets worse as the day goes on. Your feet might feel stiff when you first wake up or after sitting for a while.

The pain doesn’t always stay in your feet. Because flat feet change your alignment, you might develop problems in your knees, hips, or lower back. Your body compensates for the lack of arch support, and over time, this puts stress on joints higher up the chain.

According to Better Health Victoria, some adults also notice their shoes wearing unevenly or that their feet turn outward when they walk.

Should I Actually Be Worried?

Here’s a simple test: if your flat feet aren’t bothering you, they probably don’t need treatment. Plenty of Australian adults have flat feet and never need to see a podiatrist.

However, you should book an appointment if you’re experiencing:

• Pain that interferes with your daily activities or exercise routine
• Swelling along the inside of your ankle
• Difficulty standing on your toes
• A noticeable change in your arch height, especially if it’s only one foot
• Your foot starting to turn outward at the ankle

One-sided flat feet are particularly important to address. If only one arch has dropped, it often signals a problem with the posterior tibial tendon that could worsen without treatment.

What Actually Helps (And What Doesn’t)

The internet is full of miracle cures for flat feet, but most adults don’t need surgery or expensive interventions. Treatment focuses on managing symptoms and preventing progression.

Custom orthotics are often the first line of defence. These aren’t the flimsy inserts you buy at the chemist. Proper orthotics are made specifically for your feet after a thorough biomechanical assessment. They support your arch, redistribute pressure, and help correct your alignment when you walk. You can learn more about flat feet in adults treatment at Happy Feet Podiatry, where orthotics are custom-made following detailed gait analysis.

Supportive footwear makes a genuine difference. Look for shoes with firm heel counters, adequate arch support, and enough room in the toe box. Thongs and ballet flats might be convenient, but they offer virtually no support for flat feet.

Strengthening exercises can help, particularly for the muscles that support your arch. Your podiatrist can show you specific exercises to do at home. These won’t create an arch where none exists, but they can improve stability and reduce pain.

Some people benefit from strapping or taping techniques that provide temporary support. This is especially useful during flare-ups or when you need to be on your feet for extended periods.

Anti-inflammatory medications can help manage pain and swelling, though they’re treating symptoms rather than the underlying issue. Your GP can advise on appropriate options.

When Surgery Becomes the Conversation

Most adults with flat feet never need surgery. It’s typically reserved for severe cases where conservative treatments haven’t worked and pain significantly impacts quality of life.

Surgical options range from tendon repairs to bone realignment procedures. Recovery can take months, and outcomes vary depending on the specific procedure and your overall health. Australian podiatrists usually exhaust all non-surgical options before considering referral to an orthopaedic surgeon.

Living Well With Flat Feet

Once you understand what’s happening with your feet, managing them becomes straightforward. Most people find that combining proper footwear with orthotics makes a significant difference to their comfort levels.

Pay attention to your activity levels. If you’ve been sedentary and suddenly take up running, your flat feet might protest. Build up gradually and invest in proper athletic shoes designed for flat feet or overpronation.

Maintaining a healthy weight reduces stress on your feet and can prevent symptoms from worsening. Even modest weight loss can make a noticeable difference to foot pain.

Regular check-ups with your podiatrist help catch problems early. They can monitor changes in your foot structure and adjust your treatment plan as needed.

Frequently Asked Questions

Can flat feet in adults be corrected without surgery?

While you can’t permanently recreate a fallen arch without surgery, most adults manage flat feet successfully with conservative treatments. Custom orthotics, appropriate footwear, and strengthening exercises effectively control symptoms and prevent progression in the majority of cases. Surgery is rarely necessary unless there’s severe tendon damage or debilitating pain that doesn’t respond to other treatments.

Are flat feet covered by Medicare or private health insurance?

Medicare doesn’t typically cover podiatry visits for flat feet unless you have a chronic disease management plan from your GP. Private health insurance with extras cover usually includes podiatry, though annual limits apply. Custom orthotics may be partially covered depending on your level of cover. It’s worth checking your specific policy details before your appointment.

How long does it take to adjust to orthotics for flat feet?

Most people need two to four weeks to fully adjust to custom orthotics. Your podiatrist will usually recommend wearing them for a few hours each day initially, then gradually increasing wear time. Some temporary discomfort is normal as your feet adapt to the new support, but sharp pain isn’t. If you’re experiencing significant discomfort after the adjustment period, contact your podiatrist as the orthotics may need fine-tuning.
