You’ve just spent a small fortune on custom orthotics, or maybe just a decent pair of off-the-shelf ones that promised to fix your dodgy ankle. Now they’re sitting there, looking all technical and important, and you’re holding them next to your sneakers. The big question pops into your head: do you remove shoe insoles for orthotics? It feels like a bit of a no-brainer, doesn’t it? Like putting a new filter in your car and just leaving the old one in there.
But then you start second-guessing. Are they designed to sit *on top* of the existing insole? Is there some weird synergy happening if you leave them in? I’ve wasted enough cash on gear that didn’t work because I followed common sense that turned out to be stupid. This is one of those moments where you need clarity, not a corporate marketing spiel.
So, let’s cut through the noise and get to the real deal about whether you remove shoe insoles for orthotics. It’s usually more straightforward than you think, but knowing the ‘why’ is half the battle.
The No-Brainer Answer (usually)
Look, most of the time, the answer is a resounding YES, you absolutely remove the existing shoe insoles. Think of it like this: your orthotics are designed to provide specific support and alignment. They have their own shape and structure, often with built-in arch support, heel cups, or other corrective features. If you leave the factory-made insole in your shoe, you’re essentially adding an extra layer of material between your foot and the intended support system of the orthotic. This can mess with the fit, the feel, and most importantly, the biomechanical function of the orthotic itself.
Imagine trying to balance on a wobbly platform that’s already sitting on another slightly uneven surface. That’s what happens when you stack insoles. The orthotic won’t sit correctly, it might slip around, and the angles it’s supposed to create to correct your gait or posture get all muddled. I’ve had people tell me their expensive orthotics felt ‘weird’ or ‘uncomfortable’ – nine times out of ten, it was because they hadn’t removed the original insoles. Their feet were basically getting two conflicting messages about where to sit.
The factory insoles are generally there for basic cushioning and a bit of conformity to the shoe’s shape. They’re not built with the specific therapeutic intention that custom or even good over-the-counter orthotics possess. Removing them allows the orthotic to interface directly with the shoe’s base and, more importantly, with your foot’s natural contours, giving it the best chance to do its job effectively. The edge of the orthotic often has a slightly thicker rim designed to cup the heel, and if the original insole is there, that rim can end up sitting too high, pushing your heel out of its intended position.

When It Gets a Little Fuzzy
Now, I’m not going to lie and say it’s *always* a hard yes. There are a few exceptions, though they are rare and usually involve specific types of footwear or orthotics.
Some very minimalist shoes, or certain types of athletic shoes designed for a very specific feel (like some minimalist running shoes or rock climbing shoes), might have insoles that are actually integrated into the shoe’s construction, or are so thin they’re barely there. In these cases, forcing an orthotic in might be tricky. However, even then, the advice from podiatrists and orthotic specialists is overwhelmingly to remove whatever is removable. If the insole is glued in, you might have a problem, but that’s a shoe design issue, not an orthotic issue.
I once bought a pair of ultra-lightweight trail runners that had these bizarre, contoured foam inserts. I spent about an hour trying to jam my orthotics in over them, convinced I was doing it wrong. They just felt clunky and unstable. Turns out, those foam things were actually part of the shoe’s internal support structure, and they *were* meant to be removed, but they were glued in with some sort of industrial adhesive that I, in my infinite wisdom, tried to pry out with a butter knife. Messy, sticky, and utterly pointless. I ruined the shoe and the orthotic fit for nothing. The real lesson? If it looks like it’s meant to come out, try to remove it gently. If it’s clearly bonded, then it’s a different ballgame and you might need to reconsider the shoe or the orthotic.

The ‘why’ Behind the Removal
So, why is this removal so critical? It boils down to a few key biomechanical principles. Your orthotics are designed to correct specific issues. They might be trying to:
- Control overpronation (your foot rolling inward too much).
- Support a flat arch.
- Alleviate plantar fasciitis pain by providing better heel and arch support.
- Improve alignment from the foot up, which can affect knees, hips, and even your back.
If you leave the original insole in, you’re essentially creating a barrier that prevents the orthotic from making direct contact with your foot’s anatomy. This interference means the orthotic can’t do its job of guiding your foot through a more neutral or corrected motion. The support elements of the orthotic might not align with the bony landmarks they’re supposed to interact with. It’s like trying to use a high-tech steering wheel cover over a really worn-out steering wheel – you lose the direct feedback and control.
I remember a friend telling me he just shoved his insoles in over the factory ones because he was worried about breaking his new orthotics. He wore them for a week and complained about foot pain. I finally saw him and he was walking like a duck. We took his shoes off, and sure enough, the orthotics were bunched up and tilted sideways because the original insoles were too soft and squishy. That was my ‘aha!’ moment: the softness of the original insole was actually *hindering* the rigidity and intended correction of the orthotic. The American Podiatric Medical Association (APMA) generally advises that orthotics should fit snugly into footwear, which implies replacing the existing insole.

What If Your Orthotics Feel Thin?
Sometimes, people get new orthotics and they feel a bit thin compared to the plush cushioning of their old shoe insoles. This leads to the question: do you remove shoe insoles for orthotics, especially if the orthotic feels less padded?
This is where you have to trust the science behind the orthotic. They are designed for *support* and *correction*, not necessarily for the same level of soft cushioning you might find in a standard insole. Think of it like wearing a supportive sports bra versus a padded fashion bra. One is for function, the other for aesthetics or comfort. Your orthotics are the sports bra for your feet.

However, if the difference in thickness is so extreme that it makes your shoe fit poorly (e.g., your heel slips out, or your toes feel crammed), then you might have an issue with the shoe itself. You need a shoe that can accommodate the orthotic. Some shoes are deeper than others. If the orthotic is significantly thicker than the original insole, and your shoe was already a snug fit, you might need to consider a shoe with a more generous volume. But the primary goal is to remove the existing insole first, then assess the fit.
Do I Need to Remove Insoles for Custom Orthotics?
Yes, almost always. Custom orthotics are specifically molded to your feet and are designed to be the primary support structure within your shoe. Leaving the original insole in will alter their intended fit and function, often reducing their effectiveness and potentially causing discomfort.
Can I Put Orthotics on Top of the Shoe’s Original Insole?
While you *can* physically place them on top, it’s generally not recommended. This practice, known as ‘stacking,’ can lead to a poor fit, instability, and prevent the orthotics from providing the correct support and alignment. It’s like trying to build a stable tower with a weak, slippery base.
What If My Orthotics Are Very Thin?
If your orthotics are significantly thinner than the original insoles, you might experience a change in cushioning. However, their primary purpose is support and correction, not necessarily plush comfort. If the thinness causes a poor shoe fit (e.g., heel slippage), you may need to consider shoes with more depth or volume to accommodate the orthotic properly.
A Quick Comparison of Insole Scenarios
| Scenario | Action Required | Verdict |
|---|---|---|
| Standard Shoe with Removable Insole | Remove original insole, insert orthotic. | Recommended: Allows orthotic to function as intended. |
| Shoe with Glued-In Insole | Assess if the shoe can accommodate the orthotic without removal. If not, consider a different shoe. Attempting to pry out glued insoles can damage shoes. | Use with Caution: May compromise orthotic fit and function. |
| Minimalist Shoe with Integrated Insole | Generally, remove if possible. If not designed for removal, the shoe may not be suitable for standard orthotics. | Questionable Fit: May not work well with most orthotics. |
| Stacking Orthotic on Top of Original Insole | Do not do this if avoidable. | Not Recommended: Compromises fit, support, and stability. |

Final Verdict
So, do you remove shoe insoles for orthotics? In 99% of cases, the answer is yes. It’s the fundamental first step to getting the intended benefits from your investment in foot health. Leaving the original insole in is like buying a race car and then putting mud tires on it – you’re fundamentally undermining its purpose.
My own journey with foot pain involved a lot of trial and error, and I can’t tell you how many times a simple oversight like this caused me weeks of frustration. I spent nearly $350 testing different insoles and shoes, only to realize the issue was just leaving the stock insert in. It’s a small step that makes a massive difference.
If you’re unsure about your specific shoe or orthotic combination, the best bet is to consult with the podiatrist or specialist who provided your orthotics. They can give you tailored advice based on your foot condition and the specific products involved. But as a general rule, get that original insole out. Your feet will thank you for it.
