At a Glance: When Orthotics Should Be Replaced

Orthotics should generally be reviewed by a podiatrist at least once a year to ensure they are still providing the right level of support.

The lifespan of orthotics can vary significantly depending on their design, materials, how often they are used and the way an individual walks. While the structural shell of a custom orthotic may remain effective for several years, the top covers, cushioning and control elements often wear sooner and may need refurbishing or adjustment.

Signs your orthotics may need attention include the return of foot pain, visible wear to the top cover or cushioning, reduced stability, or a noticeable change in how your shoes or gait feel.

A professional podiatry assessment can determine whether your orthotics simply need refurbishment or adjustment, or whether it is time for a replacement.

How Long Do Orthotics Last?

Whatever stage of life we’re in, our feet carry an extraordinary workload. Orthotics work quietly in the background, absorbing pressure and helping distribute weight more evenly as you walk, stand and move throughout the day. If you’ve started to notice you don’t feel quite as supported lately, you may be wondering if it’s time to replace your orthotics.

Like a well-loved pair of shoes, orthotics are subject to ongoing mechanical stress. Every step gradually compresses the materials and alters the structure that provides support. Over time, even well-crafted orthotics can lose their ability to control movement and absorb shock effectively.

The lifespan of orthotics depends on several factors, including their quality, how they are made, how frequently they are used, and the individual biomechanics of the person wearing them. In particular, a patient’s gait pattern can have a significant impact on how quickly certain parts of the orthotic experience wear.

Over-the-counter orthotics are mass-produced and designed to provide general support. Because they are made from softer materials and not tailored to an individual’s biomechanics, they typically last between six months and one year before the support begins to break down.

Custom orthotics, by contrast, are made specifically for your foot structure and gait mechanics. Using more durable materials and precise moulding techniques, they often last between two years and five years, although this can vary depending on activity levels, body weight, footwear choices and the surfaces you walk on regularly.

For example, someone who runs frequently or spends long days on hard flooring may experience wear sooner than someone who uses their orthotics primarily for everyday walking.

Signs Your Orthotics Need Replacing

Even high-quality custom orthotics will eventually reach the point where they no longer provide optimal support. Recognising the early signs of deterioration can help prevent symptoms from returning or worsening.

Common indicators include:

The return of pain or discomfort.
If foot, heel, knee or lower-back pain that previously improved with orthotics begins to reappear, it may indicate the support has weakened.

Reduced stability or support.
You may notice your feet feel less secure inside your shoes, or that standing and walking feels subtly different from when the orthotics were new.

Visible wear and tear.
Cracked shells, flattened cushioning, worn top covers or compressed materials can all reduce the orthotic’s effectiveness.

Changes in balance or gait.
Orthotics help guide how your foot moves through each step. When they lose structural integrity, the foot may begin to compensate again, affecting stability and alignment.

Persistent odours or hygiene issues.
While not always a structural issue, older orthotics can harbour bacteria over time, particularly if used daily.

Sometimes these changes occur gradually, which is why many patients do not immediately notice them until discomfort returns.

What Happens if You Don’t Replace Your Orthotics?

Does it really matter if you don’t replace your orthotics? It’s important to remember that orthotics do not cure many foot conditions. However, research shows they play an important role in managing symptoms, controlling or slowing the progression of certain problems, and reducing pressure on vulnerable areas of the foot while supporting a more natural gait pattern.

When orthotics are functioning well, symptoms such as pain, fatigue or instability may be significantly reduced, and in some cases eliminated altogether.

However, when orthotics begin to break down, their ability to provide the needed support diminishes.

Without adequate support, the foot may gradually revert to the movement patterns that originally contributed to discomfort or injury. This can lead to the return of symptoms such as pain, instability or fatigue when walking or standing for longer periods.

In some cases, worn orthotics may even contribute to new areas of pressure within the foot if the structure becomes distorted.

Regular reviews with a podiatrist help ensure that both your feet and your orthotics continue to work together effectively.

Best Practice for Replacing Orthotics

Whether you are new to custom orthotics or simply aware it’s time to renew yours, here are a few tips on best practice for replacing orthotics.

• Schedule a podiatry appointment every six months. This ensures that your feet and orthotics are regularly assessed and any issues are addressed before they become problems.
• Talk to your foot care specialist about any changes in activity level and/or change to the type of footwear you’re using. Both aspects can impact the life of your orthotics. At times, there may need to be a change made to the orthotics based on changes in lifestyle or shoe type.
• Invest in the kind of thorough assessment you receive from qualified and professional podiatry experts. This includes a foot, nail and lower limb assessment, gait analysis, doppler test for circulation, and biomechanical assessment to get a whole picture of the effect your feet (and your orthotics) are having on your body.
• Replace your orthotics as advised by your specialist foot care team. Your whole body will thank you for it.
