How Often Do I Need To Replace My Orthotics?

Custom foot orthotics are medical devices prescribed by your podiatrist to manage pain, improve function and reduce excessive load through the feet and lower limbs. They work by altering how forces are distributed during standing, walking and running, helping injured or overloaded tissues recover.

One of the most common questions we are asked at My Family Podiatry is how long orthotics last and when they should be replaced. The answer depends on several factors, including the type of material they are made from, how often they are worn and what condition they were prescribed for.

Our podiatrists in Albany Creek regularly review orthotics for patients across North Brisbane to ensure they are still doing their job properly.

How Long Do Orthotics Usually Last?

There is no single lifespan that applies to every orthotic. Some people may only need orthotics for a short period, while others benefit from long-term use. In general, most custom orthotics last anywhere from one to three years, but this can vary significantly.

Rather than focusing on a fixed timeframe, it is more important to understand the factors that influence how quickly orthotics wear out or become unsuitable.

Factors That Affect the Lifespan of Orthotics

The Type of Orthotics

The materials used to manufacture orthotics play a major role in both comfort and durability. Broadly speaking, there are three main materials used in custom foot orthotics.

EVA orthotics: EVA orthotics are what we most commonly prescribe at My Family Podiatry. EVA allows for excellent comfort and shock absorption while still providing the support needed to manage many foot and lower limb conditions. One of the major advantages of EVA is that it can be easily adjusted in clinic to fine tune fit and comfort as your needs change. EVA orthotics are available in a wide range of densities, from very soft through to very firm, including dual and tri density designs. We use high quality EVA systems, including Paromed options, to tailor orthotics to each individual.

3D printed orthotics: 3D printed orthotics are a newer option and are particularly useful when footwear space is limited. They are commonly prescribed for low profile shoes where a firm and supportive device is required without taking up much room inside the shoe. These orthotics can be printed in different densities, ranging from firmer designs for support through to slightly softer options for comfort. Like all orthotics, they still require regular review, but they tend to maintain their shape well over time.

Polypropylene orthotics: Polypropylene is one of the older materials used in orthotic manufacturing. These devices are typically very rigid and are often made as a three quarter length shell that sits under the arch rather than extending to the toes. While polypropylene orthotics are durable and hold their shape well, many people find them hard underfoot and less comfortable for everyday wear. For this reason, we do not routinely prescribe polypropylene orthotics at My Family Podiatry.

The most suitable material depends on your footwear, activity levels and the condition being treated, which is why regular review is important.

How You Use Your Orthotics

Your daily activities have a significant impact on how quickly orthotics wear.

People who run regularly, work long hours on their feet or perform manual labour often place greater repetitive load through their orthotics. For example, marathon runners and tradespeople commonly require replacement sooner than office workers who wear orthotics for shorter periods each day.

The type of footwear also matters. Tight or unsupportive shoes can cause orthotics to deform or break down faster.

The Condition Being Treated

Orthotics are prescribed for specific reasons. In some cases, they are used to manage a temporary issue such as plantar fasciitis or a tendon injury. Once the condition has resolved and strength has improved, the original orthotic design may no longer be appropriate.

In other cases, such as long-term biomechanical issues, orthotics may be required on an ongoing basis but still need periodic replacement as materials wear.

Growth in Children and Adolescents

In children and teenagers, growth is a major factor. As the foot grows, orthotics can quickly become too small or no longer sit correctly within the shoe.

As a general rule, if your child’s foot length has increased by more than one shoe size since the orthotics were made, they should be reassessed. Continuing to wear orthotics that no longer fit can reduce their effectiveness and cause new problems.

New or Returning Pain

One of the most important signs that orthotics need review is the return of pain.

If you begin to experience foot, ankle, knee or lower limb discomfort after previously doing well, it may indicate that the orthotics have compressed, lost their shape or are no longer suitable for your current needs. Pain can also signal that your activity levels or footwear have changed and the orthotics need adjustment.

How Often Should Orthotics Be Checked?

At My Family Podiatry, we recommend orthotics are reviewed at least every 12 months.

This allows us to assess:

• Wear or compression in the materials

• Whether the orthotics are still providing adequate support

• Changes in foot posture or movement

• Changes in activity levels or symptoms

At these reviews, patient's often ask if a new pair can be made so they can stop swapping their orthotics between shoes. If the orthotics are still in good condition, they may be rotated into a less frequently worn pair of shoes, such as house or garden shoes, while a new pair is made for everyday footwear.

Regular reviews help prevent small issues from turning into larger problems.

Frequently Asked Questions About Orthotic Replacement

How do I know if my orthotics are worn out?

Visible compression, cracking, loss of shape or reduced comfort are common signs. New pain is also an important indicator.

Can orthotics last longer if I only wear them occasionally?

Yes. Orthotics worn less frequently generally last longer, provided they still fit correctly and remain supportive. This is why many people ask for two pairs of orthotics so they can leave them in different pairs of shoes and

Do orthotics need replacing if I change shoes?

If your shoes are still the same size and have a removable insole, they can typically be swapped straight to the new pair. However if the shape or style has changed, a review may be helpful to ensure the orthotics are still fitting and working as they should.

Are 3D printed orthotics more durable?

This really depends on the density of EVA or 3D printed device used. Low density devices are normally easier to get used to and feel more comfortable straight away however they will wear out quicker.

Should I keep old orthotics as a backup?

As long as they are still structurally sound, we often recommend moving these to a more casual pair of shoes, perhaps your garden shoes or another casual pair rather than your everyday shoes.

When to Book an Orthotic Review

If you are unsure whether your orthotics still suit your feet, or if you have started to experience pain, it is worth having them checked. Early review can prevent unnecessary discomfort and reduce the risk of further injury.
