Many online tips recommend pouring salt into your shoes overnight to deal with moisture and bad odors. But does it actually work? Here’s a science-backed look at what salt can and cannot do—and how to use it wisely.
Salt is known for its strong moisture-absorbing ability. When placed inside shoes, it pulls out excess dampness caused by sweat or humidity, creating a drier environment and limiting bacterial and fungal growth.
Foul odors in shoes often result from bacteria thriving in moisture. By drying out the shoes, salt indirectly reduces the conditions that lead to bad smells. It may not be as effective as baking soda, but it does make a difference—especially in hot weather or after sports.
💡 Tip: For stronger deodorizing action, baking soda is still the go-to solution, but salt is a good natural first step.
Foot fungi (like athlete’s foot) thrive in warm, moist environments. By keeping shoes dry, salt helps prevent their development. It’s not a medical treatment, but it’s a good preventive habit to adopt.
– Add 2 tablespoons of salt into each shoe.
– Distribute it evenly inside.
– Let it sit overnight.
– Empty the shoes and wipe if needed in the morning.
It’s a quick, low-effort, and low-cost trick that requires no special tools.
If odor control is your main concern, try baking soda instead or alongside salt. It’s more powerful and also has mild antifungal properties.
Salt does not kill all bacteria or fungi. If you have recurring foot infections, seek medical advice and use a proper antifungal treatment. Salt is for maintenance and prevention, not for curing infections.
Salt can damage untreated leather or delicate fabrics over time. If your shoes are expensive or sensitive, test this method cautiously or use alternatives.
Salt is a simple, natural, and budget-friendly tool to help dry out shoes, reduce odor, and limit fungal risk. Just don’t expect it to cure foot problems or replace proper foot hygiene. Add it to your routine—not as a cure, but as a smart prevention tip.
