It seems like a fast and easy solution, but this common impulse can lead to a costly mistake. The decision of how to dry your athletic shoes is more critical than most people realize, impacting everything from their performance to their lifespan.
This topic matters because sneakers represent a significant investment in our comfort, health, and style. Improper drying methods can ruin their structural integrity, degrade cushioning, and even create a breeding ground for bacteria. In this article, you will learn the definitive answer to the dryer question, understand the science behind why it's often a bad idea, and discover a range of safe, effective, and faster alternatives used by athletes and shoe care experts. We’ll provide a step-by-step guide to rescuing wet shoes and preserving your footwear investment for years to come.
The Short Answer: Why the Dryer is a High-Risk Gamble
The direct answer to whether you can dry sneakers in a clothes dryer is a qualified and generally discouraged "maybe, but you probably shouldn't." While it is physically possible, the risks far outweigh the potential time savings. A standard tumble dryer subjects shoes to intense, uneven heat and forceful tumbling. This combination can be catastrophic for modern sneakers, which are engineered from a delicate balance of synthetic materials, adhesives, and foams. The primary danger is not just external melting, but internal damage you can't immediately see.
The intense heat of a dryer, often exceeding 135°F (57°C), can degrade the crucial midsole foam. Materials like EVA (ethylene-vinyl acetate) and advanced polyurethanes can shrink, warp, or become brittle when exposed to high heat, permanently compromising the cushioning and bounce that protect your joints. Furthermore, the adhesives that bond the outsole to the upper can soften and fail, leading to the dreaded "sole separation." The violent tumbling action can also batter the shoes against the drum, damaging support structures like heel counters and causing premature wear on the upper fabric.
If you are in a dire situation and choose to ignore these warnings, extreme caution is mandatory. Always use the lowest heat setting or an air-only (no heat) cycle if your dryer has one. Place the shoes inside a pillowcase or a mesh laundry bag to minimize banging, and include a couple of dry towels to help absorb moisture and cushion the impact. Never dry shoes with loose components or delicate materials like leather or suede. However, viewing this as a last resort rather than a standard practice is essential for the health of your footwear.
The Science of Sweat and Soak: What You're Really Drying
Understanding what’s inside a wet sneaker is key to choosing the right drying method. It’s not just water. A soaked shoe is a complex environment containing moisture from external sources, plus a cocktail of salts, minerals, and organic matter from sweat. This mixture, when trapped and heated, creates an ideal breeding ground for odor-causing bacteria and fungi like mildew. Simply evaporating the water quickly isn't enough; a proper drying process must also discourage microbial growth and prevent material degradation.
The construction of a typical running or training sneaker is like a sponge sandwich. The moisture-absorbing mesh upper, the foam midsole that can hold water like a sponge, and the insole all trap liquid deeply. When external heat is applied rapidly, as in a dryer, the outer layers may dry and harden first, effectively sealing moisture inside the deeper foam layers. This "case-hardening" effect can lead to prolonged internal dampness, which not only causes odors but can also lead to material breakdown from the inside out.
Therefore, the goal of drying sneakers is a gentle, thorough, and consistent process. It’s about encouraging evaporation from the inside out without applying damaging stress to the materials. This is why methods that combine airflow, moderate ambient warmth, and moisture absorption are universally recommended by shoe manufacturers. By prioritizing a complete dry over a fast dry, you preserve the chemical and physical properties of the shoe's components, ensuring they perform as designed.
The Champion's Method: Safe, Effective Drying Techniques
The safest and most effective way to dry sneakers involves no machine at all. Start by removing the insoles and laces. These items hold a significant amount of moisture and dry much faster when separated. Wipe off any excess mud or debris from the outside with a damp cloth. Then, stuff the shoes generously with crumpled newspaper, paper towels, or specialized cedar shoe trees. The stuffing material acts as a powerful moisture wick, drawing water out of the midsole and upper through capillary action.
Place the stuffed shoes in a well-ventilated area at room temperature, away from direct heat sources like radiators, space heaters, or sunny windowsills. Indirect airflow is your best friend. Positioning them near a gentle fan, an air vent, or in a breezy doorway will dramatically speed up the process by continuously replacing the humid air around the shoe with drier air. Avoid the temptation to place them on a heating vent, as the concentrated, dry heat can be just as damaging as a dryer over time.
For a tech-assisted upgrade, consider investing in electric shoe dryers or boot dryers. These devices blow room-temperature or slightly warm air directly into the shoe, facilitating evaporation without the damaging high heat of a dryer. They are a favorite among hikers, athletes, and parents. Alternatively, you can use moisture-absorbing products like silica gel packs (the ones that come in new shoe boxes) placed inside the shoes to help pull out residual dampness. Replace the newspaper every few hours until the shoes are completely dry to the touch inside and out.
Prevention and Preparation: Keeping Sneakers Dry from the Start
When Disaster Strikes: Salvaging Smelly or Soaked Shoes
Even with the best care, sneakers can fall victim to deep saturation or persistent odors. For smell mitigation, baking soda is a powerful and inexpensive ally. After ensuring the shoes are fully dry, sprinkle a generous amount of baking soda inside, let it sit overnight, and shake it out in the morning. For a more targeted approach, make sachets filled with baking soda or cedar shavings and place them inside shoes during storage. This absorbs ambient moisture and neutralizes odors continuously.
For a deeper clean and deodorization, many sneakers (check the manufacturer's label first) can be safely washed by hand or in a washing machine. Remove laces and insoles and wash them separately. Place the shoes in a mesh laundry bag or pillowcase, use a small amount of mild detergent, and select a gentle, cold-water cycle. Critically, never put them in the dryer after washing. Instead, revert to the champion's method: stuff with newspaper and air dry. This machine-wash, air-dry combination is far safer than any dryer cycle.
If shoes have been thoroughly soaked in contaminated water or have developed mildew, a sanitizing step may be necessary. After cleaning, you can lightly spray the interior with a solution of one part white vinegar to three parts water, which kills bacteria and fungi without harsh chemicals. Let them air dry thoroughly afterward. For valuable or sentimental sneakers that have suffered severe water damage, consulting a professional shoe repair service is a worthwhile investment. They have the tools and expertise to properly deconstruct, dry, and rebuild shoes in ways that home methods cannot.

Frequently Asked Questions
Can I put my sneakers in the dryer on an air-only or no-heat setting?
An air-only (no heat) tumble cycle is significantly less risky than a heat cycle, but the physical tumbling itself can still cause damage. The shoes can be thrown violently against the metal drum, damaging the upper, loosening glue, and breaking down structural elements. If you must use a dryer, always use a protective bag or pillowcase and include dry towels to cushion the impact. However, air-drying is still the universally recommended and safer method.
How long does it take to air-dry sneakers properly?
Drying time varies based on saturation, shoe materials, and ambient humidity. With the newspaper-stuffing and fan method, it typically takes 12 to 24 hours for shoes to dry completely. Very thick-soled shoes or those soaked through may take up to 48 hours. It's crucial to be patient and ensure they are dry all the way through the midsole; squeezing the midsole should not feel cool or damp.
Is it okay to dry shoes on or near a heater or in direct sunlight?
No, direct concentrated heat from a radiator, space heater, or fireplaces is not recommended. Similarly, prolonged direct sunlight can cause colors to fade and materials to become brittle over time. These methods create uneven, intense heat that can warp shapes and degrade materials, similar to a dryer's effects. Gentle, ambient, circulated air is always superior.
What should I use to stuff my shoes if I don't have newspaper?
Excellent alternatives include paper towels, clean rags, microfiber towels, or even dry, balled-up socks. You can also purchase specialized cedar shoe trees, which absorb moisture and odor, or use silica gel packs. Avoid using materials that bleed color, like certain newsprint inserts, as the ink could transfer to your shoe's interior lining.
My shoes got wet and now they smell like mildew. Can I save them?
Yes, often you can. First, ensure they are 100% dry using the proper air-drying techniques. Then, sprinkle baking soda inside and let it sit for 24 hours before vacuuming it out. For a deeper clean, wash them (if the care label allows) and use a vinegar-water spray (1:3 ratio) inside to kill mildew spores. Let them dry thoroughly again. If the smell persists, professional cleaning or odor-eliminating products designed for footwear may be necessary.
