How to Wash Merino Shoes: Easy Steps for Fresh-Looking Footwear

Washing your merino shoes might seem simple, but these shoes need special care to stay soft, comfortable, and fresh for a long time. Many people love merino wool shoes because they are lightweight, odor-resistant, and eco-friendly. But if you wash them the wrong way, you could end up with misshapen, stiff, or damaged shoes. If you want your favorite pair to look great and last longer, you need to know the right cleaning techniques—whether you’re dealing with dirt after a hike, everyday city grime, or stubborn stains.

In this guide, you’ll learn everything you need to know about how to wash merino shoes—from basic cleaning to drying and long-term care. We’ll go step by step and explain why each action matters. You’ll also find practical tips, common mistakes to avoid, and even answers to unusual problems like odor buildup and water stains. Many beginners accidentally shrink their shoes or make them less breathable, but you can avoid these headaches with the right advice. By the end, you’ll be confident caring for your merino shoes, so they always feel and look their best.

Why Merino Shoes Need Special Care

Merino wool is not like regular shoe materials such as canvas, leather, or synthetic fabric. Merino fibers are very fine, soft, and flexible. This makes merino shoes comfortable and breathable, but also more delicate. If you use hot water, harsh detergents, or strong machine cycles, the wool can shrink, lose its shape, or become rough. Unlike many athletic shoes, merino wool doesn’t have a waterproof coating, so too much water or heat can change the way it fits.

Another reason for gentle cleaning is the natural lanolin in merino wool. Lanolin acts as a built-in protector, keeping the fibers soft and helping to resist odors. Rough washing removes this natural oil, so your shoes might become scratchy and smelly over time. Taking care of the lanolin means your shoes will last longer and stay comfortable.

Merino shoes also often have foam or natural rubber soles, and these can separate from the upper part if they’re soaked or twisted. Proper cleaning keeps every part of your shoe in the best shape, inside and out.

Supplies You Need For Washing Merino Shoes

Before you start, gather all the supplies to make the process easy and effective. Using the right tools and products is just as important as your cleaning method.

• Soft brush (like a toothbrush or shoe brush)
• Mild wool detergent (look for labels like “wool wash” or “delicate”)
• Lukewarm water (cold to slightly warm, not hot)
• Clean towels (preferably microfiber or cotton)
• Mesh laundry bag (for machine washing, if allowed)
• Sponge or soft cloth
• Bowl or bucket
• White vinegar (optional, for odor removal)
• Shoe trees or crumpled paper (for drying shape)

Avoid using bleach, regular laundry detergent, or fabric softener. These can damage the wool fibers and ruin your shoes.

Preparing Your Shoes For Cleaning

Start by removing anything that could trap dirt or block cleaning. Skip this step, and you’ll end up pushing dirt further into the fabric.

• Remove laces and insoles: Take out the laces and the insoles. These parts get dirty too, but need a gentler wash.
• Shake out debris: Hold your shoes upside down and gently tap to shake out loose sand, stones, or dirt.
• Brush off loose dirt: Use your soft brush to gently scrub off dry mud, dust, or grass from the surface and the sole.
• Spot check for stains: Look for any sticky spots or stains. These may need special attention before you wash the whole shoe.

If you skip these steps, you risk rubbing dirt deeper into the wool or scratching the delicate fibers.

Hand Washing Merino Shoes

Hand washing is the safest and most recommended way to clean merino wool shoes. It gives you the most control and helps protect the fabric.

Step-by-step Hand Wash Process

• Fill a basin with lukewarm water. The water should feel comfortable to the touch—not hot, which can shrink wool.
• Add wool detergent. Use a small amount (about a teaspoon per pair). Swirl to mix until you see light suds.
• Submerge the shoes. Place your merino shoes in the water. Gently press them down so all areas get wet.
• Clean with a brush or cloth. Dip your soft brush or cloth in the soapy water. Gently scrub the outside, focusing on dirty areas. Don’t rub too hard—let the detergent do the work.
• Clean inside the shoes. Use the same brush or a sponge to gently wipe the inside lining. This removes sweat and odor.
• Rinse with clean water. Refill your basin with fresh lukewarm water. Submerge the shoes again, pressing gently to remove soap. Repeat until all detergent is gone.
• Press out extra water. Don’t twist or wring the shoes. Press gently with your hands, or use a towel to blot and squeeze out as much water as possible.

Cleaning Laces And Insoles

• Laces: Soak in the same wool detergent solution. Rub gently with your fingers, rinse, and lay flat to dry.
• Insoles: Wipe with a damp cloth and mild detergent. Don’t soak them—too much water can warp the foam or cork. Rinse with a clean, damp cloth and air dry.

Can You Machine Wash Merino Shoes?

Some brands, like Allbirds, say their merino shoes are machine washable. But this is risky, and only safe if the care label says so. If you want to use a machine, follow these tips to reduce damage:

Safe Machine Washing Steps

• Put shoes in a mesh laundry bag. This protects them from rough spinning.
• Wash laces and insoles separately. Put them in a smaller mesh bag or wash by hand.
• Use a gentle cycle. Select “wool,” “delicate,” or “hand wash” setting. Avoid heavy or hot cycles.
• Use cold or lukewarm water. Never use hot water—heat will shrink the wool.
• Add wool detergent only. Don’t use regular detergent or bleach.
• Skip the spin cycle. Or use the lowest possible spin speed to prevent stretching.

Machine washing is never as gentle as hand washing. Even if your shoes survive, the wool may lose some softness over time.

Comparison: Hand Wash Vs. Machine Wash

Here’s a quick look at the pros and cons of each method.

If you’re unsure, always choose hand washing for merino shoes.

How To Dry Merino Shoes Properly

Wool shoes should never be tossed in the dryer or put near direct heat. Drying them the wrong way is one of the most common mistakes. Wool shrinks and warps easily, so air drying is the only safe option.

Step-by-step Drying Instructions

• Remove extra water: After washing, press the shoes inside a clean towel to absorb as much moisture as possible.
• Shape the shoes: Insert shoe trees or crumpled paper (avoid newspaper ink, use plain paper or paper towels). This helps the shoes keep their shape as they dry.
• Dry in a shaded, ventilated area: Place the shoes somewhere with good airflow but out of direct sunlight. Sunlight can fade the color and damage the wool.
• Flip occasionally: Every few hours, turn the shoes over so all sides dry evenly.
• Let them dry fully: Merino shoes may take 24-48 hours to dry completely, especially if the air is humid.

Avoid These Drying Mistakes

• Don’t use a hair dryer, heater, or radiator. Direct heat will shrink or harden the wool.
• Don’t hang shoes by the heel. This can stretch out the opening and ruin the fit.
• Don’t put wet insoles back in. Wait until both shoes and insoles are fully dry before reassembling.

Tackling Tough Stains And Odors

Sometimes, regular washing isn’t enough to remove stubborn stains or strong smells. Here’s how to handle these tricky problems without harming your shoes.

Removing Stains

• Mud and dirt: Let mud dry, then brush off as much as possible before washing.
• Grass stains: Dab with a cloth soaked in diluted white vinegar (1 part vinegar to 3 parts water), then wash as usual.
• Oil and grease: Sprinkle cornstarch or baking soda on the stain. Let it sit for a few hours to absorb oil, then brush off and wash.
• Wine or juice: Blot with a damp cloth immediately. Don’t rub—this can spread the stain. Wash with wool detergent as soon as possible.

Pro tip: Don’t use strong stain removers or bleach. These will ruin the wool fibers.

Fighting Odors

Even odor-resistant shoes can start to smell if worn sockless or left damp.

• White vinegar soak: Mix one part vinegar with three parts water. Wipe the inside of the shoe with a cloth dipped in this solution, then rinse and air dry.
• Baking soda refresh: Sprinkle baking soda inside dry shoes and leave overnight. Shake out before wearing.
• Sun and airflow: Let shoes air out in a breezy, shaded spot after each wear.

If you notice strong smells after washing, make sure the shoes are drying fast enough. Slow drying can let bacteria grow.

How Often Should You Wash Merino Shoes?

Washing too often can wear out your shoes, but not washing enough leads to odor and stains. The right frequency depends on how you use them.

• Everyday wear: Wash every 1-2 months, or when dirty.
• After hiking or sports: Wash after each muddy or sweaty use.
• If shoes smell: Wash immediately to prevent bacteria build-up.

Non-obvious insight: Frequent spot cleaning (wiping dirt before it sets) means you can wash your shoes less often, which helps them last longer.

What To Do If Shoes Shrink Or Lose Shape

Mistakes happen, even if you’re careful. If your merino shoes have shrunk or lost their shape, try these tips:

• While damp, stretch them back: Put on thick socks, wear the shoes for an hour, or stuff them tightly with paper. This may restore some of the lost size.
• Use a shoe stretcher: For serious shrinking, a shoe stretcher tool can help, but be gentle.
• Condition the wool: Rub a little lanolin-based wool conditioner on stiff spots to soften them again.

Common mistake: Many people panic and use more water or heat to fix shrinking, but this usually makes things worse.

Practical Tips For Long-term Merino Shoe Care

Keeping your merino shoes clean is just one part of long-term care. Here are expert tips to get the most life from every pair:

• Rotate your shoes: Don’t wear the same pair every day. Let them air out between wears.
• Store in a cool, dry place: Avoid damp closets or hot car trunks.
• Keep shoe trees inside: This maintains shape and absorbs moisture.
• Spot clean after each wear: A quick brush removes dirt before it becomes a stain.
• Never store wet shoes: Always dry fully before putting them away.
• Avoid direct sun: Sun fades wool and weakens the fibers.
• Reapply water repellent: If your shoes have a water-resistant spray, reapply after every wash (check the brand’s instructions).
• Replace insoles regularly: Insoles wear out faster than the wool upper. New insoles keep shoes fresh and comfortable.

Non-obvious insight: Many people forget to check the soles for wear. If the rubber or foam is wearing thin, get them resoled or repaired to extend the shoe’s life.

Common Mistakes To Avoid

Mistakes can ruin even the best merino shoes. Here are the errors you should avoid, based on real experiences:

• Using hot water: Shrinks and hardens wool.
• Using regular detergent: Harsh chemicals strip lanolin and roughen fibers.
• Skipping the mesh laundry bag: Shoes can be damaged by the washing machine drum.
• Rubbing stains too hard: This frays the wool and makes stains worse.
• Drying in the sun or dryer: Causes shrinkage and color fading.
• Putting wet insoles back: Leads to a damp, smelly shoe interior.
• Storing shoes wet: Promotes mold and bacteria.

If you avoid these, your shoes will last much longer and stay comfortable.

When To Seek Professional Cleaning

If your shoes are very dirty, stained with oil, or you’re worried about damaging them, it may be worth using a professional shoe cleaner or cobbler. Look for cleaners who know how to handle wool or have experience with specialty sneakers. Sometimes, a professional touch can rescue shoes you thought were ruined.

Sustainability And Environmental Tips

One of the reasons people choose merino shoes is because they are more eco-friendly than many other shoes. Here’s how to make your cleaning routine greener:

• Use biodegradable wool detergent. These break down safely in water and are better for the environment.
• Hand wash to save water and energy. Machines use more resources.
• Air dry instead of tumble drying. Saves energy and reduces carbon footprint.
• Repair, don’t replace. Patch small holes or re-glue soles before buying new shoes.

Non-obvious insight: Old merino shoes can often be recycled or composted (check your brand’s website). Even if they seem worn out, don’t just throw them away.

Troubleshooting Unusual Problems

Sometimes, you’ll face problems that aren’t covered in basic guides. Here’s what to do:

• Shoes feel itchy after washing: You may have removed too much lanolin. Use a wool conditioner or wear socks until the softness returns.
• Water spots appear after drying: Rub gently with a damp cloth to even out the color, then let dry again.
• White marks (soap residue): Rinse again with clean water, or brush gently when dry to remove powdery spots.
• Soles separating from wool upper: Use a waterproof shoe glue to reattach, and let cure for 24 hours before wearing.

If the problem doesn’t improve, contact the shoe brand’s customer service for advice.
