Do You Actually Need Custom Orthotics? An Honest Guide

"Do I need custom orthotics?" is one of the most common questions I hear, and the honest answer is: not everyone does. Custom orthotics are a precise, effective tool for the right foot and the right problem, but they are over-prescribed in plenty of places, and under-used in others. My goal here is to help you figure out which group you're in before you spend a dollar.

Let me give you the short version first, then the detail. If you have ongoing foot, heel, or arch pain, a history of the same injury coming back, or a clear structural issue like flat feet or a leg-length difference, custom orthotics are worth assessing. If your feet feel fine and you simply want a little extra cushioning, a good off-the-shelf insole is usually all you need.

The Honest Answer: Orthotics Correct, They Don't Cure

A custom orthotic is a prescription device made from a 3D scan of your foot and a biomechanical analysis of how you stand, walk, and move. Its job is to change how load is distributed across your foot and up the chain into your knees, hips, and lower back. That correction is genuinely powerful when there's a mechanical problem to correct. But an orthotic doesn't heal tissue on its own and it isn't a substitute for addressing the things you control, footwear, load, and strength. The best results come when the device addresses the structural piece and you address the rest.

6 Signs You'd Genuinely Benefit

In the clinic, these are the patterns that tell me a custom orthotic is likely to help rather than just feel nice underfoot:

• Recurring heel or arch pain. Morning heel pain with your first steps, or arch pain that builds through the day, is a classic sign the plantar fascia is being overloaded by how your foot is functioning.
• Flat feet or noticeable overpronation. If your arches collapse inward and your ankles roll in when you stand or walk, the soft tissues on the inside of your foot and shin are working overtime.
• Foot pain from standing all day. Nurses, teachers, trades, retail, hospitality, if you're on hard floors for long shifts and your feet ache by the end, your foot may not be supporting itself efficiently.
• Knee, hip, or lower-back pain that tracks back to your feet. The foot is the foundation. A foot that collapses or rotates changes how everything above it loads, and the pain often shows up a joint or two higher.
• A leg-length difference. Even a few millimetres tilts the pelvis and loads one side more on every step. Orthotics can carry a corrective lift to level the foundation.
• Orthotics have helped you before. If a previous pair clearly reduced your pain, your biomechanics likely do respond to correction, and a worn-out or generic pair is worth replacing properly.

If two or more of these describe you, it's worth getting a biomechanical assessment to see whether a custom device is the right call.

When You Probably Don't Need Them

Just as important: when to save your money. If your feet are pain-free, your shoes feel comfortable, and you have no recurring injuries, you likely don't need custom orthotics, no matter what a kiosk scan tells you. A pressure-plate scan at a store will almost always find "something," because no foot is perfectly symmetrical. Asymmetry alone isn't a problem to be fixed. Pain, dysfunction, or a clear structural driver is. If you have none of those, a quality cushioned insole and well-fitting footwear is a perfectly good answer.

What a Real Assessment Looks Like

A proper orthotic assessment is more than standing on a scanner. It should include a history of your pain and activity, watching you actually move, looking at how your foot strikes and how your knees and hips respond, checking for a leg-length difference, and a 3D scan that captures your foot's true shape. The prescription that follows specifies the exact corrections your body needs, not a generic arch. If someone is ready to sell you orthotics without watching you move, that's a reason to pause.

A Note on Feet Under Load

Having put my own feet through marathons and ultramarathons, I pay close attention to how load travels through the arch over time, because at high mileage, a small mechanical inefficiency compounds into a real injury. That same principle applies whether you're racing 100 kilometres or standing on a concrete floor for a ten-hour shift: it's the accumulated load that matters, not a single step. I'd rather assess your feet honestly and tell you that you don't need a device than sell you one you won't benefit from.

Try These Before You Commit

If you are on the fence, there is a sensible order to work through, and an orthotic is rarely the first step.

Audit your shoes first. Most people underestimate how dead their footwear is. Midsole foam compresses long before the upper looks worn, and a shoe at the end of its life creates symptoms that look exactly like a mechanical fault in the foot. If your main pair has several hundred kilometres or a year of daily wear on it, replace that before buying anything else.

Then look at load. Pain that appeared during a training block, a job change, or a move to harder surfaces is usually telling you about volume rather than structure. Four to six weeks of sensible loading resolves a surprising amount.

Then strengthen. Calf raises, intrinsic foot work and hip stabiliser work genuinely reduce how far an arch collapses under load. For mild cases this is often enough on its own.

If you have honestly worked through all three and the same pain is still arriving at the same point, that is the signal that something structural is driving it — and that is the question a full biomechanical assessment exists to answer.

How Much of This Can You Self-Diagnose?

Some of it, and it is worth doing before you pay anyone.

Line your shoes up behind you at eye level and look at how the heels tilt and where the soles wear. Try the wet footprint test on a dry paving stone. Stand on one leg, dip the knee, and watch whether the arch flattens and the knee drifts inward.

What you cannot see for yourself is the part that matters most: what happens dynamically, at speed, under fatigue, and whether your two sides differ. Static observation catches the obvious cases and misses the ones where the collapse only appears at kilometre twenty or hour nine of a shift. That gap is the entire reason gait analysis exists.
