How to Get Rid of That Damp Smell in Shoes (Without Throwing Them Out)

To get rid of a damp smell in shoes without throwing them out: first dry them completely (this alone fixes most cases), then deodorise with baking soda or activated charcoal, treat any visible mould with a vinegar wipe, and prevent recurrence with proper storage and moisture absorbers. Almost every "ruined" pair of shoes can be saved if you catch them within a few weeks of the smell starting.

What causes the damp smell in shoes?

That damp, slightly sour, slightly earthy smell is the result of bacteria and mould feeding on three things shoes are full of: moisture, body oils, and dead skin cells. Add the warm, dark, enclosed environment inside a shoe, and you've got perfect microbial conditions.

The smell isn't a sign the shoes are gone — it's a sign they're damp. Address the moisture and the smell follows. (Worth noting: if your wardrobe itself smells musty, the shoes are picking that up too — our piece on why wardrobes smell musty covers the bigger picture.)

The complete shoe rescue process

Step 1: Dry them properly

This single step solves a surprising number of shoe smell problems. Most damp shoes never dry fully between wears, and the smell compounds. To dry properly:

• Remove insoles if possible — dry them separately
• Loosen laces fully and open the tongue
• Stuff with newspaper or a clean tea towel to absorb interior moisture, changing every few hours
• Place in a well-ventilated spot away from direct heat (heat damages glue and leather)
• Allow 24–48 hours minimum — leather often needs longer

Step 2: Deodorise with a natural absorber

Once dry, use one of these to absorb residual odour:

• Baking soda: Sprinkle 1–2 tablespoons inside each shoe, leave overnight, tap out in the morning. Repeat for 3–5 nights for stubborn smells.
• Activated charcoal sachets: Place inside each shoe. Lasts 1–2 months and is reactivated by sun exposure.
• Dry tea bags: Black tea works well. One bag per shoe, leave overnight.
• Cedar shoe trees: A premium option that also maintains shape — cedar absorbs moisture and odour while restoring form.

Step 3: Check for and treat mould

If the smell is sharply musty rather than just stale, mould is involved. Look for white or grey spots inside the shoe, especially under the insole. For leather shoes specifically, our detailed step-by-step on removing mould from leather shoes is the right starting point. The general process:

1. Take the shoes outside
2. Wipe the inside with a cloth lightly dampened in 1:1 white vinegar and water
3. Wipe with a clean damp cloth to remove vinegar residue
4. Dry thoroughly (back to step 1)
5. Deodorise (step 2)

Step 4: Wash what's washable

Canvas sneakers, fabric trainers, and most synthetic athletic shoes can be machine washed. Use a gentle cycle, cold water, a mesh laundry bag, and air-dry only. Don't wash leather, suede, or shoes with structural foam padding. For sneaker collectors specifically, our sneakers and humidity guide goes deeper into long-term collection care.

Specific solutions by shoe type

Leather dress shoes

Wipe interior with vinegar solution if mould is present. Use cedar shoe trees — they restore shape and absorb moisture simultaneously. Condition the leather exterior after the shoes have fully dried.

Sneakers and trainers

Most can be machine washed. Remove laces and insoles, place in a mesh bag, gentle cycle, cold water. Air dry fully. Insoles can be hand washed in mild soap and air dried separately.

Suede and nubuck

Never wash. Brush gently with a suede brush, treat any mould with a slightly damp cloth (very lightly), and dry thoroughly. Consider professional cleaning for valuable pieces.

Athletic shoes with foam structure

Spot clean exterior only. Internal odour responds well to baking soda or activated charcoal. Avoid machine washing as it damages the structural foam.

Boots and ankle boots

Treat as leather dress shoes. The deeper shaft can hold more moisture, so dry for longer. Boot shapers or rolled towels maintain shape during drying.

Preventing damp shoe smell

The 24-hour rule

Don't wear the same pair two days in a row. Shoes need 24–48 hours to dry between wears. Rotating two or three pairs eliminates more shoe smell problems than any other single habit.

Choose moisture-managing socks

Merino wool, technical synthetics, or moisture-wicking blends keep your feet drier than cotton, which gets damp and stays damp.

Use shoe trees

Cedar shoe trees inserted after wear absorb sweat and moisture overnight, maintaining shape and significantly reducing the conditions that breed odour.

Store properly

Don't pile shoes in a dark, sealed cupboard. Use a shoe rack with airflow. For long-term storage, use breathable shoe bags rather than plastic.

Control wardrobe humidity

A moisture absorber in the shoe closet or wardrobe keeps overall humidity in the optimal range, preventing shoes from absorbing ambient moisture between wears. For more on which option suits the space, our comparison of moisture absorbers, silica gel, and dehumidifiers covers the trade-offs.

Frequently asked questions

How long does it take to get a damp smell out of shoes?

Light smells respond to one night of baking soda. Stronger smells typically need 3–7 days of repeated drying and deodorising. Established mould smells take 2–3 weeks of consistent treatment.

Can I put shoes in the freezer to kill odour?

The freezer kills some bacteria but does nothing about moisture or fungus. It's a partial fix at best, and the smell often returns within days.

Are odour-eating products with chemicals safe?

Most commercial shoe odour sprays are safe for occasional use, but they're masking rather than treating. Address the underlying moisture first — then a quality spray finishes the job.

When should I just throw shoes out?

If mould has penetrated the structural foam or insole and won't respond to repeated treatment, or if the smell persists after professional cleaning, replacement is probably the right call. For everything else, persistence and proper drying usually win.

Shoes don't have to be a write-off the moment they start to smell. Dry them properly, deodorise patiently, control the moisture in your storage area, and the same pair will outlive the fashion cycle that brought them to you.
