How to waterproof your hiking boots: Keep your boots like new and your feet dry

Mountain boots are much more than footwear: they are your ally against mud, rain and sharp rocks. Although they often come with a water repellent finish (DWR) from the factory, it wears away with every mile travelled, every wash and even exposure to the sun. When the DWR wears off, water stops slipping off and starts seeping in, turning your boots into an uncomfortable and dangerous sieve. But all is not lost. Knowing the right waterproofing techniques will not only save your feet from moisture, it will extend the life of your footwear. In this guide, updated with the latest methods and products, we explain how to do it. like a professional.

Why waterproof your boots? Beyond the surface

• Recovering DWRThis treatment does not affect the inner membrane (e.g. Gore-Tex), but prevents the outer layer from becoming saturated with water.
• Preventing cracks in leatherMoisturising prevents dryness and cracking.
• Optimising breathabilityA good treatment maintains the balance between waterproofing and ventilation.

Water is a hiker's worst enemy. When a boot loses its waterproofing, the leather weakens, the seams swell and the cold creeps in with every step. But the real problem is not just discomfort: a waterlogged boot is heavier, reduces your stability and increases the risk of blisters.. In addition, materials such as suede or untreated leather can crack irreversibly if they are not moisturised. So waterproofing is not an "extra", it is a maintenance ritual as essential as greasing a bicycle chain or sharpening a knife.

📋 Step-by-step guide: Methods adapted to each boot type

Not all boots are the same, and applying the wrong treatment can be worse than doing nothing at all. For example, a suede spray used on stiff leather will create a sticky coating, while a wax applied to a Gore-Tex membrane will block its breathability. Here's your guide to choosing and applying the right method:

1. Diagnosis: Identify your boot type

Before buying any product, examine your boots:

• Whole grain leather (e.g. classic models from Chiruca, Bestard, all brands have their classics): Their smooth and rigid surface responds best to waxes and dense creams that nourish in depth.
• Suede/Nubuck (e.g. Salomon Quest 4 or La Sportiva Trango): These porous materials need light sprays that do not clump the fibres.
• Synthetic with membrane (Gore-Tex, eVent): They require silicone-free sprays that respect the waterproof-breathable technology.
• Heavily worn bootsIf the leather is cracked, opt for specific fats such as the classic Sno-Seal, which seal even micro-cracks.

2. Deep cleansing: The key to effective treatment

Imagine painting a dusty wall: the paint will flake off within days. The same applies if you apply a waterproofing over dirt, you have to cleaning boots properly. Follow these steps:

1. Removes laces and insoles to access every nook and cranny.
2. Dry brushing with a natural bristle brush (such as the Nikwax or similar), removing dried mud between the soles.
3. Wash with lukewarm water and neutral soap. (avoid aggressive detergents). Use a soft cloth for delicate areas.
4. Air-dryingbut never in direct sunlight: the heat dries out the leather.

⚠️ Common mistake: Wash in hot water or dry in direct sunlight. damages fibres and DWR.

• Never use tumble dryers or heat sources.
• Pro tip: Stuff the inside with newspaper or absorbent towels (change them every 2 hours).
• Dry in a ventilated environment, away from UV light.

Practical example: Do your boots smell musty? After washing them, put a bag of activated carbon inside for 24 hours. It will absorb odours without damaging the materials.

3. Application of the treatment: Professional techniques

For full grain leather (waxes/creams):

• Warm the wax between your hands so that it penetrates better.
• Apply with a microfibre cloth in circular movements, insisting on seams and folds.
• Leave on for 10 minutes and polish with a soft bristle brush. ResultA satin finish that repels water and nourishes the leather.

For suede/nubuck (sprays):

• Shake the can vigorously and spray from a distance of 15 cm.
• Don't rub: let the product absorb naturally.
• Pro tip: Use a cold hairdryer to fix the treatment without damaging the fibres.

For membranes (silicone-free sprays):

• Apply two thin coats, allowing 2 hours drying time between coats.
• Product: Grangers Performance RepelGore-Tex compatible and biodegradable.

Green option: Mixing beeswax and coconut oil (1:2 ratio) to create a moisturising paste. Ideal for vegan leathers or people with sensitive skin.

Post-treatment maintenance

After waterproofing, store your boots in a place where they will not be damaged. cool and darkaway from heat sources. If you store them in a cupboard, insert a small bag of silica gel to avoid dampness. And remember: repeat the treatment every 3-4 monthsor after exposure to heavy rain or snow.

❌ Common mistakes (and how to avoid them)

• Using wax on membranesClogs pores and eliminates breathability.
• Apply product on dirt: Reduces efficiency by 70%.
• "More product = better protection".False. Excess wax clogs the pores of the leather and reduces breathability.
• Ignoring the seams: The 90% of the leaks start here. Use an old toothbrush to apply treatment to these areas.
• Using expired productsSprays lose efficacy after 2-3 years. Check the expiry date.

ℹ️ FAQs: Expert answers

Can I use normal shoe cream?
No. Most contain silicones that create a plastic layer, blocking breathability.

How do I know if the DWR is worn?
Make the drop testPour water over the surface. If it doesn't form rolling droplets, it's time to reapply.

Do home remedies work?
Only for emergencies. For example, the glycerine soap gives a temporary shine, but does not waterproof.
