Look, we’ve all been there. That lingering smell, that vague feeling of grime. You stare at your favorite insoles, the ones that feel like clouds underfoot, and a dangerous question creeps into your mind: can I put shoe insoles in the washer?
My own journey into the abyss of questionable laundry habits started with a pair of pricey running insoles. They were… unpleasant. I tried scrubbing them with a toothbrush, a process that took about forty minutes and left my hands smelling vaguely of old socks and regret. Then, a thought, an impulse, a moment of pure, unadulterated laziness struck me.
Why not just toss them in with my gym clothes? What could possibly go wrong? Turns out, a lot. That experience taught me a valuable lesson about what happens when you assume the washing machine is a magical de-grime-ifying box for *everything*.
The Great Wash Test: What Really Happens
So, you’re staring at those insoles, maybe they’re from your work boots, your hiking shoes, or even just your comfy everyday sneakers. They’ve seen some action. They’ve absorbed sweat, dirt, and probably a bit of your existential dread after a long day. The big question looms: can I put shoe insoles in the washer? The short, blunt answer for most is a resounding NO, but let me explain why this isn’t always a simple yes or no.
When I first started really getting into shoe care, I spent about $150 testing various “specialty cleaners” for insoles. Most of them were just fancy-smelling soap, frankly. I remember one particularly pungent concoction that promised to “revitalize” them, but it just made them smell like a cheap air freshener and left a weird, sticky residue. My mistake was thinking there was a magic bullet product. The real answer lies in understanding the materials.

Why the Washing Machine Is Often a No-Go
Most insoles are made of materials that just don’t play well with the aggressive agitation and high heat of a washing machine. Think EVA foam, memory foam, gel inserts, or even cork. The tumbling action can break down the structural integrity of these materials. It’s like putting a delicate sponge through a rock tumbler – it’s going to come out misshapen and less effective.
Then there’s the heat. Many insoles, especially those with gel or specialized cushioning, can melt or warp under high temperatures. This can ruin their shock absorption capabilities and make them downright uncomfortable. I once tried washing a pair of orthopedic insoles that had some sort of synthetic gel layer; they came out stiff as cardboard and felt like walking on a brick. It was a humbling, foot-aching lesson. Seven out of ten people I’ve talked to about this made the same assumption I did: if the shoe can get wet, the insole can too. (See Also: How To Clean Canvass Shoes)
Material Breakdown: What Your Insoles Are Made Of
Understanding the material is your first line of defense against insole destruction. Here’s a quick rundown of common culprits:
- EVA Foam: This is super common, lightweight, and provides good cushioning. Machine washing can compress it, reducing its bounce and support over time.
- Memory Foam: Fantastic for comfort, but heat and aggressive washing can cause it to break down unevenly, leading to lumps and loss of its conforming properties.
- Gel Inserts: These often have a liquid or semi-liquid core. The washing machine can puncture these or cause the gel to disperse unevenly, rendering them useless.
- Cork: Natural and good for support, but cork can swell and disintegrate when fully saturated and agitated for extended periods.
The ‘can I Put Shoe Insoles in the Washer?’ Test Results
I’ve put a few pairs through the wringer, literally and figuratively, over the years. My initial thought process was, “How different can they be from shoe liners?” Bad assumption. One pair of cheap, generic insoles I tried to wash ended up coming out looking like a deflated balloon, all lumpy and uneven. They lost all their cushioning. Another pair, some fancied-up insoles I bought online for $40, completely delaminated. The top fabric layer separated from the foam base. Utter junk.
So, while the machine might get them technically ‘clean’ of surface dirt, it often sacrifices their functionality. It’s like trying to fix a leaky faucet by hitting it with a hammer – you might solve one problem, but you’re creating three more. The subtle construction of an insole matters far more than you’d think.

When a Gentle Hand Wash Might Work
Okay, so the washing machine is generally a bad idea. But does that mean you’re doomed to smelly feet forever? Not necessarily. For less delicate insoles, a gentle hand wash is often the way to go. You’re essentially replicating the fabric care instructions you’d find on a nice sweater, but for your feet’s primary support system.
Grab a basin, some mild soap (dish soap works wonders if it’s greasy, otherwise a gentle hand soap), and cool water. Gently rub the insoles, paying attention to high-friction areas. Don’t scrub too hard; you’re not trying to get paint off a wall. Rinse thoroughly. The key here is minimal agitation and no harsh chemicals.
Drying Is Crucial: Don’t Make Another Mistake
After washing, the drying process is just as important. You absolutely cannot put insoles in the dryer. The heat will destroy them, just like the washing machine. Lay them flat on a towel, out of direct sunlight and away from heat sources. I usually stick them near a fan on a low setting. This can take anywhere from 12 to 48 hours, depending on humidity and material thickness. Patience is your friend here. Resist the urge to speed things up.
I once tried to speed up the drying of some wool insoles by placing them near a radiator. Big mistake. They shrunk noticeably and became incredibly stiff. It felt like I had put a small, stiff board in my shoe. That was after spending around $75 on those particular insoles, thinking they were superior because they were wool.

A Contrarian View: Some Insoles Can Take It
Now, here’s where I might ruffle some feathers. Everyone says you can’t wash insoles. And for the most part, they’re right. But. There are exceptions. I’ve found that some very basic, thin, fabric-covered insoles designed for everyday shoes, the kind you might get for a couple of bucks, can actually survive a very gentle wash cycle on their own. I’m talking about a delicate cycle, cold water, no spin if possible, and definitely no other clothes in there to beat them up.
I disagree with the blanket ‘never wash them’ rule because it ignores the vast spectrum of insole construction. If an insole feels like a simple piece of reinforced cardboard with a cloth top, it’s probably going to handle a gentle wash better than a thick, multi-density foam insert with gel pockets. The reason this advice isn’t more common is that most people don’t bother to differentiate, and it’s safer to just tell everyone ‘no’ to avoid widespread damage. But for the truly adventurous and discerning, a very cautious machine wash might be possible for *certain* types.
When to Just Replace Them
Honestly, if your insoles are heavily degraded, excessively smelly even after a good hand wash, or falling apart, it’s probably time for new ones. They’re not meant to last forever. Consumer Reports has occasionally touched on shoe care, and while they don’t specifically test insole washing, their general advice on prolonging the life of footwear always emphasizes gentle treatment and appropriate cleaning methods, which usually means avoiding harsh machine cycles for delicate components.
Thinking about replacement is also a good way to get better performance. I spent a lot of my early shoe-wearing life thinking that any insole was better than no insole. That’s not true. A poorly constructed or worn-out insole can actually cause more problems, leading to aches and pains that feel like they’re coming from your whole leg. It’s like trying to use a worn-out tire on your car; it compromises the entire system.
My Personal Insole Wash Disaster Story
I remember one specific incident vividly. I had a pair of premium athletic insoles, the kind that promised to reduce foot fatigue and improve performance. They were about $60 and I treated them like gold. For months, they were amazing. Then, the smell started. It was… potent. I tried everything short of a hazmat suit. Finally, in a moment of dark desperation, I threw them in the washing machine on a delicate cycle with some special sports detergent. I was already imagining them coming out fresh and revitalized. What I got was a lumpy, deformed mess. The foam had compressed unevenly, and the fabric top was pilled and faded. They were ruined, and my feet felt it for weeks.
Alternative Cleaning Methods
Beyond hand washing, a few other methods can help keep your insoles fresh without resorting to the washing machine. Baking soda is a miracle worker for odor absorption. You can sprinkle it generously on your insoles, let it sit overnight, and then shake or vacuum it off. This is a super effective way to tackle smells without any moisture involved.
Another trick is using disinfectant sprays specifically designed for shoes or athletic gear. These can kill bacteria and neutralize odors without saturating the insole material. A light misting every few days can make a big difference. I find that spraying them down after a particularly sweaty workout, then letting them air dry completely, is usually enough to keep the worst smells at bay.

| Method | Pros | Cons | Verdict |
|---|---|---|---|
| Washing Machine (Standard) | Quick, potentially removes surface dirt | High risk of damage (warping, disintegration), heat issues | Avoid at all costs for most insoles. |
| Hand Wash (Gentle, Cold Water) | Effective for many materials, preserves structure | Time-consuming, requires attention to detail | Recommended for most insoles. |
| Baking Soda Treatment | Excellent for odor, no moisture involved, safe | Doesn’t remove visible dirt or grime | Great for freshening up. |
| Disinfectant Spray | Kills bacteria, neutralizes odors, quick | Can leave residue if overused, doesn’t remove dirt | Good for maintenance between washes. |
| Washing Machine (Delicate, Cold, Alone) | Might work for *some* very basic insoles | Still carries risk, not universally applicable | Use with extreme caution, only for specific types. |
Faq: Your Burning Insole Questions
Can I Put Fabric Shoe Insoles in the Washer?
It depends on the fabric and the backing. Most fabric-topped insoles have a foam or gel backing that can be damaged by the washing machine. While the fabric itself might survive, the underlying structure could warp or break down. A gentle hand wash is almost always a safer bet, even for fabric ones.
Will My Gel Insoles Be Ruined in the Washer?
Almost certainly, yes. Gel insoles are particularly vulnerable to the heat and agitation of a washing machine. The gel can leak, disperse unevenly, or the casing holding the gel can rupture, rendering the insole useless and potentially making a mess in your machine.
How Do I Get Rid of the Smell in My Insoles Without Washing Them?
The best non-washing method is to use baking soda. Sprinkle it liberally on the insoles, let it sit for at least a few hours (overnight is better), and then shake or vacuum it off. You can also use specialized shoe deodorizer sprays or charcoal inserts, which absorb moisture and odors.
Can I Put My Custom Orthotics in the Washer?
Absolutely not. Custom orthotics are expensive, precision-molded devices. They are made from materials that will be irrevocably damaged by a washing machine, and the cost to replace them is significant. Stick to gentle hand washing with mild soap and cool water, and always air dry them completely.
What If My Insoles Are Just Dirty, Not Smelly?
For general dirt and grime, a gentle hand wash is still your best bet. Use cool water and a mild soap. You can use a soft brush (like an old toothbrush) to gently scrub away stubborn dirt, but avoid anything abrasive. Rinse thoroughly and air dry. Machine washing is overkill and risks damaging the materials for a problem that a simple hand wash can fix.
Final Thoughts
So, after all that trial and error, the short answer to ‘can i put shoe insoles in the washer?’ is mostly no, but with a few caveats for the truly adventurous or desperate. The materials used in most insoles simply aren’t built for the abuse a washing machine dishes out. You’re far more likely to end up with a ruined insole and a lingering smell that’s just… different, than you are to achieve true cleanliness.
My own experience with a pair of supposedly performance-enhancing insoles turning into lumpy bricks after a machine wash still haunts me. It’s a visual reminder that not everything belongs in the laundry cycle. For those pricey custom orthotics or even your favorite everyday foam inserts, stick to the gentle approach: a cool hand wash, mild soap, and patient air drying.
If they’re truly beyond saving, and believe me, you’ll know when they are – if they smell like a science experiment gone wrong or feel like they’re made of concrete – then it’s time to invest in a fresh pair. Your feet will thank you for it, and you’ll avoid another costly mistake.
