Honestly, I’ve thrown some questionable things in the washing machine over the years, hoping for a miracle. My poor, unsuspecting gym bag once endured a rogue smoothie incident. It did not end well. So, when the dreaded mud and general griminess of a particularly brutal trail run caked my favorite trainers, I had the same thought: can I machine wash running shoes?
The internet is awash with conflicting advice, most of it written by people who probably think ‘athletic wear’ means anything you might wear to a very casual coffee shop. They spout generic instructions that feel more like a user manual for a toaster than advice for your actual, sweat-soaked, pavement-pounding companions.
Here’s the unvarnished truth, straight from someone who has spent way too much money on shoes only to ruin them with a bad cleaning choice. Forget the fluff; let’s talk about what actually works and what’s just a recipe for expensive, smelly disappointment.
So, Can I Machine Wash Running Shoes? The Verdict Is Murky.
Look, the short answer is: maybe, but it’s a calculated risk. Most running shoe manufacturers will tell you “hand wash only.” Why? Because those delicate foams, adhesives, and breathable mesh uppers are not designed for the violent tumbling of a washing machine. Think of it like this: you wouldn’t put your car’s engine through a car wash, would you? Same principle. The intense agitation can, and often does, break down the glues holding your shoes together, warp the sole, and generally make them fall apart faster than a cheap suit in a rainstorm.
I learned this the hard way. About five years ago, after a particularly muddy OCR race, my brand new, top-of-the-line Brooks looked like they’d wrestled a swamp monster. In a fit of ‘I’ll just fix this,’ I tossed them in. They came out… mostly clean, but the upper felt weirdly stiff, and the cushioning just wasn’t the same. It felt like I’d aged them by a decade in one wash cycle. That set me back a good $150 and taught me a valuable, albeit expensive, lesson about respecting what these complex pieces of footwear are made of.

Why Your Running Shoes Hate the Washing Machine
The high-speed spin cycle is the real villain here. It’s like a tiny, angry tornado for your shoes. This violent action can dislodge the internal structure, loosen the reinforcements in the heel and toe, and even damage the reflective elements. Plus, the heat from the water, even on a ‘cold’ setting, can be too much for some of the synthetic materials. Running shoes are engineered for performance, not for surviving a domestic laundry appliance’s tantrum. (See Also: How To Clean White Shoe Strings)
Consider the construction. You’ve got breathable mesh panels that are designed to wick moisture, not to withstand being pummeled against a metal drum. The internal cushioning systems, often a complex mix of foams and gels, can be compressed unevenly or permanently deformed by the sheer force of a wash cycle. It’s not just about surface dirt; it’s about the structural integrity.
It’s a shame, really, because who has time for meticulous hand-washing after every single run? Nobody, that’s who. But the consequences can be significant.
What Happens If You Ignore the Hand-Wash-Only Rule?
My friend, bless her heart, decided to machine wash her neon pink Hoka Clifton 8s. She’d done it with every shoe she’d ever owned. Why stop now? She figured the washing machine was her personal dirt-destroying fairy godmother. The shoes came out looking… well, they looked like they’d gone ten rounds with a particularly aggressive washing machine. The mesh was puckered, the sole had a strange, wavy appearance, and the once-plush interior felt rough and unforgiving. She tried to run in them the next day, and apparently, they felt like cardboard boats. A complete waste.
This is a common outcome. The structural integrity is compromised. You might notice:
- Reduced cushioning and support
- Peeling adhesives, especially around the sole and toe box
- Warped or misshapen parts of the shoe
- Degraded breathability and odor retention issues
- Shorter overall lifespan for the shoe

The Only Way to (slightly) Safely Machine Wash Running Shoes
Okay, I know some of you are thinking, ‘But what if I’m careful?’ If you are absolutely determined to risk it, and I mean *absolutely* determined, there’s a method. This is what I’ve fallen back on maybe twice in the last year when a pair was beyond salvage by any other means. And even then, I held my breath.
First, remove the laces and insoles. Wash these separately by hand. You can put the insoles in a pillowcase, but the laces are best scrubbed with a brush and some mild soap. Next, stuff some old towels into the shoes. This helps them maintain their shape and absorb some of the impact inside the drum. Use a mesh laundry bag – this is non-negotiable if you’re going this route. It offers a minimal layer of protection. Select the gentlest cycle on your machine – think ‘delicate’ or ‘hand wash’ if it has one. Use cold water and a very small amount of mild detergent. NO fabric softener. Ever. Seriously, don’t. And for the love of all that is holy, skip the dryer. Air dry them, preferably in a well-ventilated area away from direct heat or sunlight. Stick them on a cooling rack or prop them up so air can circulate around them. (See Also: How To Clean White Brooks Shoes)
This is less about cleaning and more about damage control. It’s the Hail Mary pass of shoe cleaning.
Hand Washing: The Boring, but Effective, Method
If you want your running shoes to last and perform as they were designed to, hand washing is your best bet. It sounds like a chore, and frankly, it is. But it’s significantly less risky than throwing them in the machine.
Here’s the process that has worked for me, even for my mud-caked trail runners:
- Prep: Remove laces and insoles. Bang the shoes together outdoors to dislodge as much loose dirt and debris as possible. You’ll look like a mad person, but it’s effective.
- Scrub: Use a soft brush (an old toothbrush works wonders) and lukewarm water mixed with a tiny amount of mild dish soap or specialized shoe cleaner. Gently scrub away the dirt. Pay attention to the nooks and crannies of the sole.
- Rinse: Use a damp cloth or sponge to wipe away the soap residue. Don’t drench the shoes. You want to rinse, not soak.
- Insoles & Laces: Wash these separately. A gentle scrub with soap and water is usually sufficient.
- Dry: This is crucial. Stuff the shoes loosely with paper towels or newspaper (avoid colored ink that might bleed) to absorb moisture from the inside. Place them on a drying rack in a cool, dry place away from direct sunlight or heat. Change the paper stuffing every few hours if they are particularly soaked. This whole process can take 24-48 hours, depending on humidity.
This method preserves the integrity of the materials and adhesives. It’s a bit more effort, but the payoff in shoe longevity is immense. I’ve found that this technique can revive even shoes that I thought were goners, making them feel almost new again.

A Contrarian View: When Machine Washing Might Be Less Evil
Everyone says hand wash. I disagree, with a caveat. If your shoes are made of simple, durable materials and are already nearing the end of their life, and you are desperate, a machine wash might just be okay-ish. Think of a very basic, all-synthetic trainer that has already logged hundreds of miles. The structural integrity is likely already compromised. In this specific, rare scenario, a gentle machine cycle could be a last-ditch effort to get them a little cleaner before they’re retired to gardening duty. But for anything remotely new, expensive, or made with delicate cushioning systems, it’s still a gamble I wouldn’t take.
Comparing Cleaning Methods
| Method | Pros | Cons | My Verdict |
|---|---|---|---|
| Machine Wash (with precautions) | Fast(er), less hands-on effort | High risk of damage, potential for reduced lifespan, voids warranty | Last resort for old, basic shoes. High risk. |
| Hand Wash (the right way) | Safest for shoe integrity, preserves cushioning and support, extends lifespan | Time-consuming, requires effort and attention to detail | The only recommended method for most shoes. Worth the effort. |
| Spot Clean / Wipe Down | Quick, minimal risk, good for light dirt | Doesn’t tackle deep dirt or odor, not effective for heavy soiling | Excellent for daily maintenance between deeper cleans. |
The ‘why’ Behind the Shoe’s Construction
Understanding why running shoes are built the way they are helps explain why machine washing is a bad idea. The lightweight, breathable mesh uppers are critical for ventilation, keeping your feet cool and dry during long runs. This mesh is often bonded or stitched in specific ways to provide support without adding bulk. The midsole, the cushioning layer that absorbs impact, is usually made of complex foam compounds like EVA or TPU. These foams are engineered to compress and rebound consistently. The outsole provides traction and durability, often with intricate tread patterns that can trap mud. All these components are held together by specialized adhesives that are designed to be flexible yet strong, but they can be weakened or dissolved by excessive heat and agitation. A study by the American Podiatric Medical Association noted that proper footwear maintenance, including appropriate cleaning methods, can contribute to foot health by ensuring shoes maintain their intended support and cushioning.

Faqs: Your Burning Questions Answered
Can I Put Running Shoes in the Dryer?
Absolutely not. The heat from a dryer can warp the sole, melt adhesives, and shrink or damage the synthetic materials. Always air dry your running shoes. This is perhaps more important than the washing method itself.
What’s the Best Way to Get Mud Out of Running Shoes?
For heavy mud, let it dry first. Then, bang the shoes together outdoors. Use a stiff brush (not wire!) to get into the treads and brush away the dried mud. For stubborn bits, a damp cloth and mild soap will help, but always follow up with thorough air drying.
Can I Use Bleach on My Running Shoes?
No! Bleach is far too harsh. It will degrade the fabrics, weaken the adhesives, and likely discolor your shoes permanently. Stick to mild detergents or specialized shoe cleaners.
How Often Should I Clean My Running Shoes?
This depends on how much you run and in what conditions. For everyday road runners, a quick wipe-down after each run might suffice for weeks. For trail runners or those who run in wet conditions, a more thorough clean every 3-5 runs is advisable. Listen to your shoes; if they start to smell or look particularly grimy, it’s time.
Final Thoughts
So, to circle back to the original question: can I machine wash running shoes? My advice, after years of trial and error and a few expensive mistakes, is to avoid it if at all possible. The risk of irreversible damage to the shoe’s structure, cushioning, and lifespan is just too high. That moment of convenience isn’t worth the potential for regret.
If your shoes are truly caked in grime and you feel a machine wash is your only option, proceed with extreme caution, as outlined earlier. Think of it as a medical procedure for a dying patient – it might help, it might kill them faster. But for the vast majority of situations, especially with newer or more expensive shoes, the gentle, albeit slower, process of hand washing is the only sane choice.
Next time your shoes look like they’ve been through a war zone, grab that soft brush and some soapy water. Your feet, and your wallet, will thank you in the long run.
