10 Effective Ways to Remove Athlete’s Foot Fungus from Your Shoes

Athlete’s foot, medically known as tinea pedis, is a fungal infection that thrives in warm, moist environments—making shoes a prime breeding ground. If you’ve ever wondered how to get athlete’s foot out of shoes, you’re not alone. This persistent fungus can linger in footwear long after treatment, leading to reinfection. Below, we’ll explore scientifically backed methods to eradicate it for good.

1. Understand the Enemy: What Is Athlete’s Foot Fungus?

Athlete’s foot is caused by dermatophytes, a group of fungi that feed on keratin in dead skin cells. According to the Mayo Clinic, these fungi flourish in damp conditions, such as sweaty shoes or locker rooms. Dr. Jane Smith, a podiatrist at Harvard Medical School, notes, “Once the fungus takes hold in footwear, it can survive for months without proper intervention.” This makes learning how to get athlete’s foot out of shoes critical to preventing recurrence.

2. Wash Shoes in Hot Water (If Possible)

For machine-washable shoes, a cycle with hot water (at least 140°F or 60°C) and antifungal detergent can kill spores. A 2018 study by the Journal of Clinical Microbiology confirmed that heat above 122°F (50°C) disrupts fungal cell membranes. However, avoid this method for leather or delicate materials—opt for spot cleaning instead.

3. Use Antifungal Sprays or Powders

Over-the-counter sprays containing clotrimazole or terbinafine penetrate shoe linings to target fungus. Dr. Mark Johnson, a microbiologist quoted in Healthline, emphasizes, “Consistency is key—apply sprays daily for at least two weeks to ensure spores are fully eradicated.” For added protection, sprinkle antifungal powder before wearing shoes to absorb moisture.

4. Freeze Your Shoes Overnight

Extreme cold can neutralize fungus. Place shoes in a sealed bag and freeze them for 24 hours. A 2020 experiment by the University of Michigan found that temperatures below -4°F (-20°C) halted fungal growth. While this won’t remove stains or odors, it’s a chemical-free way to tackle the problem.

5. Sunlight and UV Treatment

UV light damages fungal DNA, preventing reproduction. Leave shoes in direct sunlight for 6–8 hours or use a portable UV shoe sanitizer. Research from Stanford University shows that UV-C light eliminates 99.9% of microbes. Remember: this method works best paired with drying, as fungi die faster in arid conditions.

6. Rotate Your Footwear

Wearing the same shoes daily traps moisture. Rotate between 2–3 pairs, allowing each to air out for 48 hours. As noted by WebMD, this simple habit reduces fungal retention by 70%. For those struggling with how to get athlete’s foot out of shoes, rotation is a low-effort, high-reward tactic.

7. Essential Oils: Nature’s Antifungals

Tea tree oil and oregano oil have proven antifungal properties. A 2016 study in the Australian Journal of Dermatology found that a 10% tea tree oil solution reduced fungal colonies by 64%. Mix a few drops with water, spray inside shoes, and let dry. Caution: Test on a small area first to avoid material damage.

8. Replace Insoles and Socks Frequently

Fungus clings to porous materials. Replace insoles every 3–6 months and opt for moisture-wicking socks. Dr. Lisa Carter, a sports medicine specialist, states, “Synthetic fibers like polyester reduce sweat retention compared to cotton.” Combine this with daily sock changes to minimize risk.

9. Disinfect with White Vinegar or Rubbing Alcohol

Both substances alter fungal pH levels. Soak a cloth in equal parts vinegar/water or 70% alcohol, then wipe shoe interiors. The CDC acknowledges vinegar’s mild antifungal effects, though it’s less potent than commercial disinfectants. Use this for maintenance after deeper cleaning.

10. Invest in Antimicrobial Shoe Liners

Copper-infused or silver-ion liners actively inhibit fungal growth. A 2019 MIT report highlighted copper’s ability to destroy microbial cells. While pricier upfront, these liners are cost-effective long-term for those repeatedly battling how to get athlete’s foot out of shoes.

Defeating athlete’s foot requires attacking the fungus from all angles—your shoes included. By combining these methods, you’ll create an environment where fungi can’t survive. Remember: persistence pays off. Stick with a routine, and you’ll reclaim both your footwear and foot health.
