Can You Put Walking Boots in the Washing Machine?

1. The Direct Answer

2. Why People Ask This Question

The temptation is understandable. You’ve just returned from a classic UK hike—perhaps a squelching traverse of the Pennine Way or a muddy climb in the Brecon Beacons. Your boots are caked in a thick, stubborn layer of British mud, and the thought of spending 30 minutes scrubbing them by hand is daunting. The washing machine, sitting there promising a quick and effortless solution, seems like a modern fix for an age-old problem.

This question arises from a desire for convenience in the face of the specific challenges of hiking boot care in the UK. Our trails are rarely dry and dusty; they are often wet, boggy, and abrasive. Getting your boots clean isn’t just about aesthetics; it’s a crucial part of maintenance that prevents dirt from damaging the materials and compromising performance. The question, therefore, isn’t born from laziness, but from a practical search for an efficient way to manage essential gear maintenance.

3. What Happens If You Do It? The Real Risks

While the only “pro” is a few minutes of saved effort, the list of cons is extensive and severe. Putting your boots through a wash cycle is a gamble where the best-case scenario is a shortened lifespan, and the worst is immediate and total failure.

The Perceived Benefit: Convenience

The single, fleeting advantage is avoiding a manual clean. You can throw them in, press a button, and walk away. However, this convenience comes at a very high price.

The Real Risks: A Breakdown of Your Boots

Modern hiking boots are complex pieces of engineering, combining multiple materials and technologies that are not designed to withstand a machine wash. Here’s a breakdown of the damage you can expect: Machine washing can compromise the integrity of the materials, leading to delamination or loss of waterproofing. Many of the waterproof hiking boots characteristics, such as breathability and flexibility, may fade, leaving your boots less effective in challenging conditions. Moreover, the harsh agitation can break down the cushioning, reducing comfort during long hikes. Additionally, exposing your boots to the intense forces of a washing machine can lead to early wear and tear, ultimately costing you more in replacements. It’s essential to prioritize proper care techniques to maintain waterproof hiking boot durability and ensure they perform optimally for years to come. Regular maintenance, such as hand cleaning and reapplying waterproofing treatments, will help protect your investment and extend their lifespan.

• Structural Failure (Glue Delamination): Hiking boots are held together by powerful adhesives that bond the sole to the midsole and the midsole to the upper. The high heat of a wash cycle can weaken and dissolve these glues, causing the sole to peel away from the boot—a catastrophic failure known as delamination.
• Material Damage: Leather is a natural material that will dry out, crack, and become brittle when exposed to harsh detergents and excessive heat. Synthetic fabrics and foams can warp, shrink, or lose their structural integrity. The tumbling action can also cause physical abrasion, scuffing, and tearing.
• Waterproofing Failure: If your boots have a waterproof membrane like GORE-TEX, a machine wash is a death sentence. The membrane is a delicate layer that can be punctured or torn by the violent tumbling. Furthermore, detergents can clog the microscopic pores of the membrane, destroying its breathability and stripping the Durable Water Repellent (DWR) coating from the outer fabric.
• Deformation and Fit Issues: The heat and force can cause the boot to lose its carefully designed shape. This can ruin the fit, creating pressure points, hot spots, and making the boot uncomfortable and unwearable.

4. When Is It OK to Machine Wash Boots?

It is never acceptable to put modern walking or hiking boots in a washing machine. Every major manufacturer, from Scarpa to Salomon, and every reputable outdoor retailer explicitly advises against it. The risks of permanent damage are simply too high for any type of hiking boot, whether it’s full-grain leather, synthetic fabric, or a hybrid.

The only potential exception might be for some minimalist, canvas-style shoes or water sandals, but even then, you should always check the manufacturer’s specific care instructions first. For the kind of footwear discussed in our guide to the Best Hiking Boots UK 2025, the answer is an unequivocal no.

5. The Better Alternative: The 15-Minute Manual Clean

The correct way to clean walking boots is far less daunting than it seems and is the cornerstone of proper hiking boot care. This simple, effective hand-washing method will protect your investment, maintain performance, and take no more than 15 minutes. Regularly cleaning walking boots after walks not only prolongs their lifespan but also ensures that they remain in top condition for future adventures. Additionally, it prevents dirt and debris from building up, which can compromise the materials and affect waterproofing. Taking the time to care for your boots will enhance your hiking experience and keep your feet comfortable on challenging terrain.

Step-by-Step Guide to Hand-Washing Hiking Boots

1. 1. Preparation: Find a suitable spot outside or use a utility sink. Bang the soles of the boots together to dislodge the worst of the caked-on mud and stones.
   2. Remove Laces and Insoles: Take out the laces and the insoles. This allows you to clean the boots thoroughly, especially around the eyelets and tongue, and lets everything dry properly. Laces can be washed separately, and insoles can be cleaned with a brush and lukewarm water.
   3. Initial Scrub (Water Only): Use a soft-to-medium brush (an old vegetable or toothbrush works well) and lukewarm water to scrub away all the surface dirt and mud from the uppers and the soles.

1. 1. Deep Clean (If Needed): For stubborn dirt, use a specialist footwear cleaner like Nikwax Footwear Cleaning Gel or Granger’s Footwear Cleaner. Avoid household detergents or bar soaps, as they can damage leather and waterproof membranes. Apply the cleaner and gently scrub, then rinse thoroughly with clean water.
   2. Drying (The Crucial Step): Never use direct heat (radiators, fires, hairdryers) as this will crack leather and damage glues. Stuff the boots loosely with newspaper or kitchen roll to absorb internal moisture, replacing it when it becomes damp. Let the boots air dry naturally at room temperature in a well-ventilated area. A fan can speed up the process significantly.

1. 1. Reproofing (Waterproof Boot Care UK): To maintain waterproof boot care UK hikers need, it’s essential to reproof your boots periodically. The best time to do this is while the boots are still damp from cleaning, as this helps the treatment absorb into the material. Use a treatment appropriate for your boot’s material—a wax-based product for full-grain leather, or a spray-on proofer for fabric, suede, or nubuck. This restores the DWR coating, ensuring water beads off the surface.

6. Common Mistakes to Avoid

Beyond the cardinal sin of machine washing hiking boots, UK walkers often make these other common care mistakes:

• Force Drying with Heat: Placing wet boots on a radiator or by a campfire is the fastest way to destroy them. It causes leather to crack and irrevocably damages the adhesives holding the boot together.
• Using the Wrong Cleaning Products: Standard laundry detergents and harsh soaps can strip the natural oils from leather and damage the delicate waterproof membranes. Always use a dedicated footwear cleaner.
• Storing Them While Dirty or Damp: Putting boots away muddy and wet allows dirt to abrade the materials and can lead to mould growth. Worse, storing them damp for long periods can cause hydrolysis, a chemical breakdown of the polyurethane (PU) in the midsole, causing it to crumble.
• Forgetting to Clean the Inside: Salt from sweat can build up inside the boot, drying out and damaging the lining and leather over time. Wiping the inside with a damp cloth is good practice.
• Neglecting to Reproof: Many people assume that because their boots have a GORE-TEX liner, they don’t need to treat the outer fabric. Maintaining the DWR coating with regular reproofing is vital for breathability and overall performance.

7. Quick FAQ

How often should I clean my walking boots?

You should perform a quick clean (brushing off mud) after every muddy walk. A full, deep clean as described above should be done whenever the boots are heavily soiled or before you plan to reproof them, typically every few months for a regular hiker.

What’s the best way to dry boots overnight on a multi-day hike?

This is a classic UK hiking challenge. Remove the insoles. Stuff the boots with any spare dry clothing (like your best hiking socks), newspaper from a pub, or even toilet paper. Place them in the driest, best-ventilated part of your tent or B&B room, away from direct heat. For optimal results, check the boots periodically and replace the stuffing as it becomes damp. Remember, drying hiking boots effectively can prevent odor buildup and prolong the life of your footwear. Once they are dry, put the insoles back in and ensure everything is ready for your next adventure.

My GORE-TEX boots are leaking, can I fix them?

It’s difficult. Leaks are usually caused by punctures or wear-and-tear in the membrane itself [14]. While you can’t patch the inner membrane easily, ensuring the outer fabric is properly cleaned and reproofed can sometimes improve water resistance. For significant damage, contact a Gore-certified repair centre.
