How Long Do Orthotics Last? When to Replace Your Insoles

Your orthotics are working hard every day — absorbing impact, correcting your gait, and protecting your joints. But like any load-bearing device, they wear out. Here’s exactly how long different types of orthotics last and the clear signs it’s time for a replacement.

Lifespan by Orthotic Type

Over-the-Counter (OTC) Insoles

Typical lifespan: 6–12 months for daily use. Budget foam insoles (like PowerStep basic models) compress and lose their arch support within 3–6 months of daily use. Higher-quality OTC insoles (PowerStep Pinnacle, PowerStep Pinnacle) hold up for 9–12 months with normal use. If you’re on your feet for 10+ hours daily, expect the shorter end of the range. See our recommended OTC orthotics guide.

Custom Orthotics (Rigid/Semi-Rigid)

Typical lifespan: 2–5 years for the shell; 1–2 years for the top cover. The rigid plastic shell of a custom orthotic maintains its corrective shape for many years. However, the soft top cover (the foam or leather material your foot rests on) compresses and degrades faster. Most podiatrists recommend replacing the top cover every 12–18 months and the full device every 3–5 years, or when the shell shows visible wear or cracking.

Custom Orthotics (Soft/Accommodative)

Typical lifespan: 1–2 years. Soft orthotics made from foam or similar materials compress more quickly than rigid designs. Diabetic accommodative orthotics often need replacement annually to maintain the cushioning protection that prevents pressure wounds.

Children’s Orthotics

Replace every 6–12 months (or with each shoe size change). Children’s feet grow rapidly — an orthotic that fit at size 3 won’t provide correct support at size 5. Growth often outpaces wear as the replacement criterion.

7 Signs Your Orthotics Need Replacing

1. Your heel pain has returned. If plantar fasciitis symptoms that were controlled start flaring again, your orthotics may have lost their corrective support. This is the most common sign.

2. Visible compression or flattening. Hold your orthotic up and look at the arch. If it looks noticeably flatter than when it was new, it’s no longer providing adequate support.

3. You can feel the floor through them. If the cushioning has compressed to the point where you feel the hard floor through the orthotic, the protective and supportive function is gone.

4. Cracks or breaks in the shell. A cracked rigid orthotic can create pressure points and cause new pain. Replace immediately.

5. The top cover is worn through or peeling. Surface wear on the cover doesn’t always mean the orthotic is done, but it can indicate it’s time for a cover replacement or full replacement.

6. Your shoes wear unevenly in a new pattern. If your shoe wear pattern changes (e.g., you used to wear the outer heel and now you’re wearing the inner heel), your orthotic may no longer be correcting your gait effectively.

7. You’ve had significant weight changes. Major weight gain or loss changes the load on your orthotics. An orthotic designed for your weight at 200 lbs may not be optimal at 160 lbs — and vice versa.

How to Extend Orthotic Life

Rotate between two pairs of shoes so orthotics get drying time. Remove orthotics from shoes overnight to allow material recovery. Keep orthotics dry — moisture degrades foam and adhesives. Replace top covers on custom orthotics rather than the full device when the shell is still functional. Avoid leaving orthotics in hot cars (heat degrades foam rapidly).

OTC Replacement vs. New Custom Fitting

If your condition has changed significantly since your last custom orthotics — significant weight change, new injury, surgery, aging-related arch collapse — it’s worth getting reassessed rather than simply reordering. Your orthotic prescription may need to change.

If your OTC orthotics have run their course and you’re finding you need to replace them every few months because the relief isn’t lasting, that’s a signal your condition may require custom devices.

Frequently Asked Questions

Q: Can I wash my orthotics?
OTC foam insoles can be gently hand-washed in cool water and air dried. Custom rigid orthotics should be wiped clean with a damp cloth only — submersion can damage the materials.

Q: My custom orthotics are 8 years old but feel fine. Do I need new ones?
Possibly. The shell may still look intact, but the corrective angles may have subtly shifted over years of use, and your foot position and needs may have changed. A check-up with your podiatrist is worthwhile after 4–5 years regardless of appearance.

Q: Are replacement OTC insoles as good as new custom orthotics?
Not for corrective purposes. But if your original custom orthotic was for cushioning and comfort rather than structural correction, a quality OTC replacement may serve you well while you get a new fitting scheduled.
