We’ve all been there. You glance down at your favorite pair of tennis shoes—the ones that have carried you through weekend errands, gym sessions, and spontaneous walks in the park—and you realize they look like they’ve survived a mud wrestling match. The fabric is stained, the soles are grimy, and that faint odor is no longer ignorable. You know they need a deep clean, but the thought of scrubbing them by hand for an hour feels exhausting. So, you wonder: can I just toss them in the washing machine?

The short answer is yes, you absolutely can wash many types of tennis shoes in a washing machine. But before you throw caution (and your sneakers) to the wind, it’s important to understand the “why” and “how” behind the process. Washing machines are powerful tools, but they can also be destructive if you don’t follow a few simple rules. Think of this as your friendly guide to giving your shoes a spa day—without ruining them.

Why Machine Washing Works (and When It Doesn’t)

At its core, washing a shoe in a machine is about using controlled agitation, water, and detergent to break down dirt and grime that has embedded itself into the fabric and stitching. The machine’s drum rotates, sloshing water through the shoe’s material, while the detergent lifts oils and particles away. It’s the same principle as washing a pair of jeans, but with a few critical differences—shoes have glue, foam, and sometimes delicate structural components.

Here’s the catch: not every shoe is built for the machine. If your tennis shoes are made of delicate materials like leather, suede, or mesh with heavy plastic overlays, the machine’s force can warp them, loosen the glue, or cause the fabric to fray. Similarly, shoes with built-in LED lights, electronic components, or very old, brittle soles are best left for hand washing. But for the vast majority of modern athletic sneakers made from canvas, synthetic mesh, or polyester blends, a gentle machine cycle is perfectly safe.

Step-by-Step: The Right Way to Wash Tennis Shoes in a Machine

Let’s get into the practical steps. This isn’t a “set it and forget it” kind of task—it requires a little prep work. But I promise, the payoff is worth it. Follow this routine, and you’ll extend the life of your shoes while keeping them looking fresh.

Step 1: Remove the Laces and Insoles
This is non-negotiable. Laces can get tangled around the machine’s agitator (if you have a top-loader) or ball up into knots. More importantly, the insoles often hold the most odor and sweat. Take them out and wash them separately, either by hand with mild soap or in a lingerie bag on a gentle cycle. This also allows water and detergent to reach every nook and cranny inside the shoe.

Step 2: Knock Off Loose Dirt
Before the shoes ever touch water, give them a good tap together outside or use a soft brush to remove caked-on mud, pebbles, or debris. You don’t want that grit swirling around in your machine—it can scratch the drum or get lodged in the shoe’s fabric. A quick wipe with a dry cloth helps, too.

Step 3: Pre-Treat Stubborn Stains
If you have grass stains, grease spots, or scuff marks, apply a small amount of laundry detergent or a stain remover directly to the area. Let it sit for about 10 minutes. This pre-treatment gives the detergent time to break down the stain before the wash cycle begins. For white soles, a paste of baking soda and water can work wonders.

Step 4: Protect the Shoes (and Your Machine)
Place each shoe inside a mesh laundry bag or a pillowcase. This prevents them from banging against the drum during the cycle, which can cause noise, damage to the shoe, or even imbalance the machine. If you don’t have a mesh bag, a clean pillowcase tied off with a rubber band works just fine. Also, add a few towels or other soft items to the load—this helps cushion the shoes and balances the machine’s spin.

Step 5: Choose the Right Cycle and Settings
This is where most people make mistakes. Always use a gentle or delicate cycle with cold or lukewarm water. Hot water can melt the glue that holds the shoe together, especially in cheaper sneakers. Set the spin speed to low to reduce stress on the fabric. For detergent, use a small amount—about half of what you’d use for a regular load. Too much soap can leave residue inside the shoes, making them stiff and causing that weird, sticky feeling.

Step 6: Skip the Fabric Softener
I know it’s tempting, but fabric softener coats the fibers of your shoes, which can reduce breathability and trap odors. It can also break down the foam in the midsole. Stick with a standard liquid detergent or a sports-specific detergent designed for activewear.

Drying: The Most Critical Step

Here’s a hard truth: the washing machine is only half the battle. How you dry your shoes is what truly determines whether they’ll come out looking great or completely ruined. Never—and I mean never—put wet tennis shoes in a dryer. The high heat will warp the shape, shrink the fabric, and potentially melt the glue. Instead, follow these steps:

• Stuff them with paper towels or newspaper. This helps absorb excess moisture and maintains the shoe’s shape. Change the paper every few hours until the shoes are mostly dry.
• Air dry in a well-ventilated area. Place them near a fan or in a room with good airflow. Avoid direct sunlight, which can fade colors and cause materials to crack.
• Be patient. Full drying can take 12 to 24 hours, depending on the thickness of the sole and the humidity. Don’t rush it by using a hairdryer or radiator—uneven heat can cause the sole to peel away from the upper.

If you’re in a hurry, some dryers have a “no heat” or “air fluff” setting. You can use that, but I’d still recommend checking the shoes every 15 minutes to make sure they aren’t getting too warm.

When You Should Avoid the Machine Altogether

I mentioned earlier that not all shoes are machine-friendly. Let me be more specific about the red flags. If your tennis shoes have any of the following features, stick to hand washing with a soft brush and mild soap:

• Leather or suede uppers – These materials can crack, warp, or lose their texture.
• Exposed foam or EVA midsoles – The agitation can cause the foam to break down faster.
• Glued-on soles that are already peeling – Machine washing will finish the job of separating them.
• Vintage or collectible sneakers – The risk of damage is too high for sentimental or valuable pairs.
• Shoes with built-in electronics or lights – Water and circuits don’t mix.

Pro Tips for Long-Lasting Freshness

Once you’ve mastered the wash, you’ll want to keep your shoes cleaner for longer. Here are a few habits that make a real difference:

• Rotate your shoes. Wearing the same pair every day traps moisture and accelerates wear. Giving them a day off lets them air out naturally.
• Use shoe trees or cedar inserts. They absorb moisture and help maintain shape, especially between washes.
• Spot clean immediately. If you step in a mud puddle or spill coffee, wipe it off as soon as you can. Dried stains are much harder to remove.
• Wash them in pairs. Washing one shoe at a time can unbalance the machine. Always wash both shoes together, even if only one looks dirty.
• Consider a shoe-specific detergent. Brands like Nikwax or Granger’s make formulas that are gentle on technical fabrics and help preserve waterproof coatings.

Final Thoughts on Machine Washing Your Tennis Shoes

Washing tennis shoes in a machine isn’t a shortcut—it’s a smart, efficient method when done correctly. The key is preparation and patience. By removing laces and insoles, pre-treating stains, using a gentle cycle with cold water, and air drying slowly, you can bring your sneakers back to life without damaging them. Think of it as a routine maintenance task, not a one-time emergency fix.

And here’s the best part: once you get the hang of it, you’ll find yourself cleaning your shoes more often, which actually extends their lifespan. Dirt and sweat are abrasive over time—they break down fibers and weaken glue. A regular wash every few months (or after heavy use) keeps your shoes comfortable, odor-free, and ready for whatever your day throws at them.

So go ahead, give those tired tennis shoes a second chance. Just remember: gentle cycle, cold water, mesh bag, and air dry. Your feet—and your washing machine—will thank you.
