Ranked: 8 Super Cheap Ways to Eliminate Running Shoe Odor Under $5

Evan Chymboryk Founder • B.S. Exercise Science

I’ve been there. You walk into the mudroom after your kid gets home from soccer practice, and it hits you like a physical wall. It’s that sour, thick scent of athletic shoes that have seen better days. You spent a small fortune on those cleats, and the thought of tossing them in the trash because of a smell seems like a waste of money. But you can't exactly have guests over when the entryway smells like a locker room.

The good news is that you don't need a massive budget to fix this. In fact, you probably have most of the solutions sitting in your pantry right now. Keeping your gear fresh isn't just about social grace; it’s about making sure those expensive sneakers last more than a single season. If you've ever wondered how to safely deodorize Hoka Clifton 9s or other high-end trainers, you know that being gentle is just as important as being effective.

Why Do Running Shoes Smell So Bad?

Running shoes smell because the dark, warm, and damp environment inside the shoe is the perfect breeding ground for odor-causing particles. When sweat from your feet soaks into the fabric and foam, it stays trapped, allowing smells to intensify over time.

Your feet have thousands of sweat glands. During a hard run or a long shift at work, they produce a significant amount of moisture. This isn't just water; it's a mix of salts and oils. This condition is sometimes called bromodosis. When that moisture gets trapped in the synthetic fibers of your favorite sneakers, the odor becomes "baked in."

If you want to stop the moisture before it starts, you need a heavy-duty absorber. This is the one we keep by the door:

Can Baking Soda Really Fix Smelly Sneakers?

Baking soda works by balancing the pH levels of acidic odors and absorbing the residual moisture where smells thrive. Leaving a few tablespoons of baking soda inside your shoes overnight effectively neutralizes most common odors for just pennies.

This is the "old reliable" of the household cleaning world. To use this method, grab some standard Baking Soda from your kitchen. Sprinkle about two tablespoons into each shoe, making sure to tilt the shoe back and forth so the powder reaches the toe box. Let it sit for at least 12 hours. In the morning, shake them out over the trash or use a vacuum hose to get the excess out. It's cheap, it's easy, and it works for most mild cases of "gym bag funk."

How Does Newspaper Help With Shoe Odor?

Newspaper is highly porous and acts as a mechanical wick, pulling moisture out of the shoe's inner lining and foam. By removing the dampness that holds onto odors, it prevents smells from settling deep into the material.

Don't recycle that Sunday paper just yet. If you've been caught in a rainstorm or just had a particularly sweaty workout, grab some Old Newspaper. Ball up several sheets and stuff them tightly into your shoes all the way to the toes. The paper draws the moisture out of the fabric. This is a great trick for shoes like Hey Dudes that you don't necessarily want to throw in the washing machine every week. Change the paper every few hours if the shoes are soaking wet.

How Do Tea Bags Remove Shoe Odor?

Dry tea bags contain tannins and dried leaves that naturally absorb moisture and leave behind a subtle, pleasant scent. Placing two unused black tea bags in each shoe overnight can help pull out stale odors without using harsh chemicals.

This is a great "overnight" hack. Grab two Dry Tea Bags—black tea works best because of the higher tannin content. Simply drop them into the heels of your shoes after you take them off. While they won't tackle a professional athlete's level of stink, they are perfect for daily maintenance on work shoes or casual sneakers. Plus, they're incredibly cheap if you buy the bulk boxes.

Is Freezing Your Shoes a Real Way to Kill Smells?

Freezing shoes can temporarily pause the activity of odor-causing particles by subjecting them to extreme cold, but it rarely eliminates the smell permanently. Once the shoes warm back up to room temperature, the odor usually returns unless the underlying moisture is addressed.

You might have heard that putting your sneakers in the freezer in a Ziploc bag is a secret weapon. While it’s true that cold can stun the things that cause smells, it doesn't actually remove the "stuff" they feed on—like your dried sweat and skin cells. It’s a bit like hitting the pause button on a movie. It works for a day or two, but it’s not a long-term solution. You're better off focusing on ways to keep the shoes dry and fresh using natural oils.

I tested both side-by-side for a week. Here's what happened:

What Are the Best DIY Spray Ingredients?

The most effective DIY shoe spray consists of a 50/50 mix of rubbing alcohol and water, which helps dry out the shoe interior rapidly. Adding a few drops of lemon or eucalyptus oil can provide a fresh scent while the alcohol works to neutralize odors on contact.

If you prefer a spray but want to keep it budget-friendly, mix some isopropyl alcohol with water in a small spray bottle. Give the inside of your shoes a light mist after your run. The alcohol evaporates quickly, taking a lot of the moisture with it. Just be careful with leather shoes, as alcohol can dry out the material and cause cracking over time.

When Should You Use a Professional Natural Spray?

Professional natural sprays are necessary when DIY home remedies like baking soda or tea bags fail to reach the deep-seated odors embedded in the shoe's cushioning. These formulas use concentrated plant oils to provide a more powerful and lasting freshness than household pantry items.

Sometimes, the "home hacks" just can't keep up with a teenager’s basketball shoes or a pair of work boots worn for 12 hours a day. That's when I reach for something like the Extra Strength Shoe Deodorizer Spray. It uses the heavy hitters of nature—lemon, eucalyptus, and tea tree—to actually fix the problem rather than just hiding it. It’s a relief to know I’m not spraying harsh chemicals around my family, and the scent is bright and clean rather than "fake floral."

"I was about to throw away my son's cleats. We tried the charcoal bags and the powder, but nothing worked. One night of using the Extra Strength spray and they actually smelled like lemons instead of... well, you know. Life saver!" — Verified Customer Sarah M.

Is the natural route perfect? Mostly, but it does require consistency. Here's the honest breakdown:

At the end of the day, you don't have to choose between a smelly house and a drained bank account. Start with the free stuff—the newspaper and the baking soda. If your shoes are putting up a fight that the pantry can't win, don't be afraid to step up to a professional-strength natural solution. Your nose (and your guests) will thank you.
