Get Rid Of Smelly Gym Shoes: How To Get The Smell Out Of Gym Shoes

Do your gym shoes smell bad? Yes, you can get the smell out of gym shoes, and it’s usually quite simple! Let’s explore effective ways to make your sneakers fresh again.

The pungent odor emanating from gym shoes is a common, yet unpleasant, problem. This smell, often described as musty, sour, or even like stale cheese, is primarily caused by bacteria and fungi that thrive in warm, moist environments. When you work out, your feet sweat. This sweat gets trapped in the porous materials of your shoes. Combined with dead skin cells, it creates a perfect breeding ground for microbes. These tiny organisms consume the sweat and skin cells, releasing volatile organic compounds (VOCs) as a byproduct, which are the culprits behind the offensive smell. Fathoming the science behind shoe odor can help us tackle it effectively.

Why Do Gym Shoes Get Smelly?

Several factors contribute to the persistent smell in athletic footwear:

Sweat: Our feet have more sweat glands per square inch than almost any other part of our body. During exercise, these glands go into overdrive, producing a significant amount of moisture.
Bacteria and Fungi: The damp, warm environment inside closed shoes, coupled with nutrients from sweat and skin cells, creates an ideal habitat for bacteria and fungi to flourish.
Lack of Ventilation: Many modern athletic shoes are designed for performance, often using materials that are good at wicking moisture but not necessarily at allowing air to circulate freely. This traps moisture and heat.
Inadequate Drying: If shoes are not properly dried after each use, the moisture remains, prolonging the favorable conditions for odor-causing microbes.
Foot Hygiene: Poor foot hygiene, such as not washing feet regularly or wearing the same socks multiple times, can exacerbate the problem.

Deodorize Gym Shoes: Proven Methods to Eliminate Shoe Odor

Getting rid of that stubborn sports shoe smell removal requires a multi-pronged approach. It’s not just about masking the odor, but actively eliminating the source. Here’s how to deodorize gym shoes and achieve lasting freshness.

1. Baking Soda Gym Shoes: A Natural Powerhouse

Baking soda, or sodium bicarbonate, is a fantastic natural deodorizer. It works by absorbing moisture and neutralizing acidic odor compounds.

How to use baking soda:

Direct Application: After wearing your shoes, sprinkle a generous amount of baking soda inside each shoe. Ensure it covers the insoles and the bottom. Leave it overnight (or longer for stubborn smells).
Shake it Out: In the morning, turn the shoes upside down and shake out the baking soda. You can use a vacuum cleaner with a brush attachment to suck out any remaining powder.
Baking Soda Sachets: For a less messy approach, fill old socks, cheesecloth bags, or porous fabric pouches with baking soda. Tie them securely and place one inside each shoe when not in use. This is a great way to maintain freshness daily.

Why it works: Baking soda is alkaline, which helps to counteract the acidic byproducts of bacterial breakdown, effectively neutralizing the odor.

2. Washing Gym Shoes: The Deep Clean Approach

Washing your gym shoes can be a highly effective way to eliminate odor, but it’s crucial to do it correctly to avoid damaging the shoes.

Machine Washing:

Check the Label: First, always check the care label on your shoes. Some materials, like leather or those with delicate embellishments, are not suitable for machine washing. Most synthetic athletic shoes and canvas sneakers can be washed.
Preparation: Remove the laces and insoles. If the insoles are heavily soiled or smelly, wash them separately by hand or consider replacing them.
Washing Cycle: Place the shoes in a mesh laundry bag or pillowcase to protect them and the washing machine drum. Wash them on a gentle cycle with cold water and a small amount of mild detergent. Avoid using fabric softener, as it can affect the moisture-wicking properties of athletic shoes.
Drying: NEVER put gym shoes in the dryer. The intense heat can warp the materials, melt adhesives, and damage the shoe’s structure. Instead, air dry them. Stuff them with newspaper or paper towels to absorb excess moisture and help them keep their shape. Change the paper periodically for faster drying.

Hand Washing:

Materials: You’ll need a basin, mild detergent, a soft brush (like an old toothbrush), and clean cloths.
Process: Mix a small amount of mild detergent with cool water. Dip the brush into the soapy water and gently scrub the insides and outsides of the shoes. Pay attention to the insoles and any particularly soiled areas.
Rinsing: Wipe away the soap residue with a damp cloth. Ensure all soap is removed to prevent residue buildup.
Drying: As with machine washing, air dry your shoes away from direct heat.

3. Freezing Your Shoes: A Cold Approach to Odor

The cold can kill some odor-causing bacteria. While not as effective as deep cleaning or baking soda for significant odor issues, freezing can help reduce mild smells.

How to freeze:

Place your shoes in a sealed plastic bag. This prevents them from picking up freezer odors and protects them from frost.
Leave them in the freezer overnight.
In the morning, take them out and let them thaw completely. Air them out before wearing.

Effectiveness: This method is best for surface-level odors and works by killing a portion of the bacteria. It’s a good supplementary step.

4. Vinegar Soak: An Acidic Solution

White vinegar is another excellent natural deodorizer and disinfectant. Its acidity can help kill bacteria and break down odor-causing compounds.

How to use vinegar:

Vinegar Solution: Mix equal parts white vinegar and water in a basin or spray bottle.
Soaking Insides: If you can remove the insoles, soak them in the vinegar solution for about 30 minutes, then rinse thoroughly with water and air dry.
Spraying Inside: For shoes you can’t soak, spray the vinegar solution generously inside, ensuring it reaches all areas. Let it sit for a few hours or overnight, then air dry.
Wiping Down: You can also dampen a cloth with the vinegar solution and wipe down the inside of the shoes.

Caution: Ensure the shoes are completely dry after using vinegar to avoid promoting mold growth.

5. Sunlight Exposure: The Natural Sanitizer

Sunlight has natural antibacterial properties and can help dry out damp shoes, making it a simple yet effective method.

How to use sunlight:

Place your gym shoes in direct sunlight for a few hours.
Turn them occasionally to ensure all sides are exposed.

Limitations: While beneficial for drying and mild sanitization, sunlight alone may not be enough for heavily soiled or intensely smelly shoes. It’s best used as a complementary step.

6. Activated Charcoal: The Ultimate Absorber

Activated charcoal is renowned for its incredible ability to absorb odors and moisture. It’s a powerful shoe freshener.

How to use activated charcoal:

Purchase activated charcoal odor absorbers (often sold in porous bags).
Place one sachet inside each shoe when not in use.
You can also find loose activated charcoal; place it in small breathable bags or old socks and put them in your shoes.
Periodically, you can reactivate charcoal absorbers by placing them in sunlight for a few hours.

7. Essential Oils: Fragrant Footwear

Certain essential oils possess antimicrobial and deodorizing properties. They can add a pleasant scent while helping to combat odor.

Popular choices:

Tea Tree Oil: Known for its potent antifungal and antibacterial properties.
Lavender Oil: Offers a calming scent and has some antimicrobial benefits.
Eucalyptus Oil: Possesses antiseptic qualities.
Peppermint Oil: Provides a refreshing scent and can deter bacteria.

How to use:

Mix a few drops of essential oil with water in a spray bottle.
Lightly mist the inside of your shoes.
Alternatively, put a few drops on a cotton ball or paper towel and place it inside the shoe overnight.

Caution: Use sparingly, as too much oil can potentially stain or damage certain shoe materials. Always test on an inconspicuous area first.

8. Commercial Shoe Deodorizers and Sprays

There are many commercial products designed to deodorize gym shoes. These can include sprays, powders, and sachets.

Deodorizing Sprays: These often contain antimicrobial agents and fragrances to neutralize odors. Spray them inside shoes after workouts or daily.
Odor-Absorbing Powders: Similar to baking soda, these powders absorb moisture and neutralize smells. Sprinkle them inside and shake out later.
Shoe Fresheners: These are typically small inserts or sachets containing materials like cedarwood, charcoal, or antimicrobial compounds that absorb moisture and odor.

When choosing commercial products, opt for those that specifically target bacteria and fungi rather than just masking the smell.

How to Prevent Foot Odor and Keep Your Shoes Smelling Fresh

Prevention is always better than cure. Implementing good habits can significantly reduce or even eliminate the problem of smelly gym shoes.

1. Practice Good Foot Hygiene

This is the first line of defense against foot odor.

Wash Your Feet Daily: Use soap and water to thoroughly wash your feet, paying attention to the spaces between your toes.
Dry Your Feet Completely: Moisture between the toes is a prime spot for fungal infections and odor-causing bacteria.
Change Socks Regularly: Wear clean socks every day, and change them immediately if they become damp during the day. Opt for moisture-wicking materials like wool or synthetic blends over cotton, which holds moisture.

2. Choose the Right Socks

The material of your socks plays a crucial role in managing foot moisture.

Moisture-Wicking Fabrics: Materials like merino wool, polyester, nylon, and acrylics are designed to pull moisture away from your skin and allow it to evaporate.
Avoid Cotton: Cotton socks tend to absorb moisture and keep it close to your skin, creating a damp environment that encourages bacterial growth.

3. Rotate Your Gym Shoes

Avoid wearing the same pair of gym shoes every single day.

Give Them a Break: Allow your shoes at least 24 hours to dry out completely between wears. This is crucial for athletic shoe odor control.
Use Two Pairs: Consider having two pairs of athletic shoes and alternating between them. This ensures each pair has ample time to air out and dry.

4. Air Out Your Shoes After Every Workout

Don’t just toss your sweaty gym shoes into your bag or closet.

Immediate Airing: As soon as you take them off, loosen the laces and remove them from your gym bag.
Find a Ventilated Spot: Place them in a well-ventilated area, ideally outdoors in the shade or near an open window.

5. Use Shoe Inserts or Insoles

Certain types of insoles can help manage moisture and odor.

Charcoal Insoles: These are specifically designed to absorb odors and moisture.
Cedar Insoles: Cedarwood has natural antimicrobial properties and a pleasant scent that helps combat odor.
Removable Insoles: If your shoes have removable insoles, take them out regularly to air them separately and wash them if needed.

6. Consider Antiperspirant or Foot Powder

For excessive foot sweating, you might find these helpful:

Foot Antiperspirant: Applied to your feet, these products can help reduce sweating.
Foot Powder: Talcum powder or medicated foot powders can absorb moisture and help keep feet dry. Apply after washing and drying your feet.

7. Proper Storage

How you store your shoes when not in use matters.

Avoid Damp Places: Don’t store gym shoes in closed, dark, and damp places like the bottom of a gym bag or a poorly ventilated closet.
Open Storage: Keep them in an open area where air can circulate. A shoe rack or an open shelf is ideal.

Troubleshooting Stubborn Smells

If you’ve tried several methods and the smell persists, consider these advanced techniques:

Ozone Generators: These devices produce ozone, which can effectively kill bacteria and neutralize odors. However, they should be used with caution and in well-ventilated areas, as prolonged exposure to ozone can be harmful.
Enzyme Cleaners: Some specialized shoe cleaners contain enzymes that break down the organic compounds responsible for odor. Follow the product instructions carefully.
Professional Cleaning: For very expensive or delicate athletic shoes, consider professional shoe cleaning services that specialize in sports footwear.
