Can Old Orthotics Cause Foot Pain? Understanding When It’s Time for a Replacement

 

If you’ve been wearing the same pair of orthotics for a few years and have started to notice new aches in your feet, knees, or lower back, you’re not imagining it. One of the most common questions patients ask at Foot Care Whitby is:

“Can old orthotics cause foot pain?”

The short answer is yes — worn or aging orthotics can absolutely contribute to discomfort. But the more important question is why this happens and how to know when it’s time for a reassessment.

 

Why Orthotics Don’t Last Forever

Custom orthotics are medical devices designed to support your unique foot structure, improve alignment, and reduce stress on bones and soft tissues. But like any device used daily, they experience wear and tear.

Over time, orthotics can lose their effectiveness due to:

• Material compression — cushioning layers flatten and lose shock absorption
• Shell fatigue — the corrective structure softens or deforms
• Daily wear and friction
• Changes in your body, footwear, or activity level

When these changes occur, your orthotics may no longer support your feet the way they were originally prescribed.

 

How Long Do Orthotics Last?

At Foot Care Whitby, most patients can expect their orthotics to last:

2–4 years, depending on the materials used and your activity level.

• High‑density shells last longer than softer, accommodative devices
• Runners, walkers, and workers on their feet may wear out orthotics sooner
• Children and teens often require more frequent updates due to growth
• Older adults may need adjustments as biomechanics change with age

Even if your orthotics look fine, they may no longer be functioning as intended.

 

Signs Your Orthotics May Be Causing Foot Pain

• Returning arch or heel pain
• New forefoot pressure or burning
• Knee, hip, or lower‑back discomfort
• Feeling unstable or “rocking” in your shoes
• Orthotics sliding, squeaking, or sitting unevenly
• Visible cracks, flattening, or worn top covers

Many patients assume their original foot condition is “coming back,” when in reality, the orthotics have simply worn out.

 

How Old Orthotics Cause Pain

1. Increased stress on bones and soft tissues

Loss of support can lead to overpronation or supination, increasing strain on the plantar fascia, tibia, and metatarsals.

2. Reduced shock absorption

Flattened materials allow more impact to travel up the kinetic chain — often felt in the heels, knees, or lower back.

3. Altered gait mechanics

Uneven wear can subtly change how you walk, leading to new pain patterns.

4. Aggravation of previous injuries

Conditions like plantar fasciitis, Achilles tendinopathy, or bunion pain can flare up when support diminishes.

 

When Should You Replace Your Orthotics?

You should consider a reassessment if:

• Your orthotics are 2–4 years old
• Pain has returned
• Your activity level has changed
• You’ve switched to different footwear
• You’ve had a recent injury
• Your orthotics feel different than they used to

At Foot Care Whitby, we recommend annual orthotic check‑ups to ensure your devices are still performing optimally.

 

What Happens During an Orthotic Check‑Up?

• Review of symptoms and activity changes
• Inspection of orthotics for wear, compression, or shell fatigue
• Evaluation of how the orthotics sit in your footwear
• Gait, alignment, and biomechanical reassessment
• Recommendations for adjustments, refurbishment, or replacement

Sometimes a simple modification can extend the life of your orthotics — other times, a new pair is the best option for long‑term comfort.

 

Final Thoughts

Old orthotics can absolutely cause foot pain, but the solution is straightforward. With a proper assessment and updated support, most patients experience significant relief quickly.
