How to Restore Waterproofing on Shoes Without Damage

How to Restore the Waterproofing of Old Shoes Without Damaging the Material

Waterproof shoes are your feet’s best friend in rain, snow, mud, and beyond. But even the best waterproof shoes, like THEESE's Purpose and Flow State, can lose their water-repellent powers over time. The good news? You can restore their waterproof protection—without compromising the material or the look of your shoes.

In this guide, we’ll walk you through safe, effective methods to bring your old waterproof shoes back to life, whether they’re leather, suede, or high-performance fabric.

Why Waterproofing Fades Over Time

Even high-quality waterproof shoes lose their effectiveness after:

  • Frequent exposure to water, dirt, or harsh weather
  • Improper drying or cleaning
  • Normal wear and tear over months or years
  • Neglecting routine care and maintenance

Waterproof membranes or treatments, like DWR (Durable Water Repellent), eventually break down, leaving your shoes vulnerable to leaks, stains, and mold.

Step 1: Clean Your Shoes the Right Way

Before you reapply any waterproofing treatment, your shoes need a clean, dry surface.

Supplies You’ll Need:

  • Soft cloth or brush
  • Mild soap or shoe cleaner
  • Warm water (not hot!)
  • Towel or microfiber cloth
  • Shoe trees or newspaper for shaping

Cleaning Instructions:

  1. Remove laces and insoles.
  2. Use a damp cloth to gently wipe off dirt, debris, and old residue.
  3. For leather shoes, use a leather-safe cleaner.
  4. Let them dry naturally—no direct sunlight or heaters. Insert shoe trees to keep shape.

⚠️ Pro Tip: Never toss your shoes in a tumble dryer. It can shrink materials and damage waterproof membranes.

Step 2: Choose the Right Waterproofing Product

Different materials need different products. Here's how to choose wisely:

Material

Recommended Product

Notes

Fabric / Mesh

Waterproofing spray

Quick and even coverage

Leather

Waterproofing wax or cream

Provides nourishment and sealing

Suede

Suede-safe waterproof spray

Avoid wax; it will ruin the texture

Gore-Tex / Synthetic

DWR or performance membrane-specific sprays

Maintains breathability

Look for products labeled “breathable,” “non-toxic,” and “safe for specific materials.” Don’t use all-purpose waterproof sprays on suede or leather—they often contain harsh solvents.

Step 3: Apply Waterproofing with Care

Here’s how to apply waterproofing products safely:

For Spray Applications:

  1. Shake the can well.
  2. Hold 6–8 inches from the shoe and spray evenly across the entire surface.
  3. Use circular motions for consistent coverage.
  4. Let dry for 12–24 hours in a well-ventilated, shaded area.
  5. Repeat for an extra layer of protection if needed.

For Wax/Cream:

  1. Use a soft cloth to apply a small amount in circular motions.
  2. Let it absorb naturally—don’t overapply.
  3. Buff with a clean dry cloth.
  4. Allow the shoes to sit for several hours or overnight.

Extra Protection: Conditioning + Storage Tips

Leather conditioner is essential to keep your leather shoes from cracking after waterproofing. It restores oils and adds flexibility.

Storage Tips:

  • Keep in a dry, cool place
  • Insert shoe trees to maintain shape
  • Avoid storing in plastic boxes (trap moisture)
  • Use cedar shoe trees for odor control and moisture absorption

Fixing Damage Before Waterproofing

If your shoes have scratches, scuffs, or small tears:

  • Use a leather repair kit for leather or vinyl
  • Dye or polish for color correction
  • Apply fabric patch kits to fix breathable mesh zones

Don’t waterproof over damaged areas—this can trap moisture and cause more issues.

How Often Should You Reapply Waterproofing?

The frequency depends on how often and where you wear your shoes:

Use Case

Reapplication Schedule

Daily wear in wet climates

Every 2–3 months

Occasional hiking or travel

Every 4–6 months

Dry climates or infrequent use

1–2 times a year

THEESE Waterproof Shoes, like Purpose and Flow State, are designed with long-lasting performance membranes—but even they benefit from the occasional refresh!

Eco-Friendly Note: Choose Non-Toxic Sprays

When shopping for waterproof sprays or waxes, opt for eco-conscious brands. Many traditional sprays use PFCs (perfluorocarbons) that harm the environment. Look for options marked:

  • “PFC-free”
  • Biodegradable
  • Non-aerosol if possible

Quick DIY Waterproofing Alternatives (For Emergencies Only!)

Need a quick fix? Try these temporary hacks—but only as a short-term solution:

  • Petroleum jelly: Works on rubber boots or plastic shoes (but can stain fabric and leather)
  • Beeswax or candle wax: Rub and heat gently with a hair dryer (not ideal for suede or soft mesh)
  • Waterproof tape or patches: Good for small tears in synthetic uppers

These hacks should be your last resort, not your go-to strategy.

Final Thoughts: Give Your Shoes a Second Life

Waterproof shoes are a smart investment—and maintaining their performance doesn’t require fancy tools or risky hacks. With just a few simple steps, you can restore your shoes’ waterproof barrier and get many more miles out of them.
