What Kills Fungus in Shoes?

An antifungal spray or powder is effective at killing fungus in shoes.

Here's a more detailed breakdown of how to eliminate fungus from your footwear and prevent its return:

Methods for Killing Fungus in Shoes

Several methods can effectively eliminate fungus in shoes. Here's a breakdown:

Antifungal Sprays and Powders: These are specifically designed to kill fungal organisms. Look for products containing ingredients like miconazole, clotrimazole, or tolnaftate. Apply liberally inside the shoes, paying attention to the toe area and seams.
Disinfectant Sprays: While not specifically antifungal, some disinfectant sprays can help reduce fungal load. Look for products that kill a broad spectrum of germs.
UV Shoe Sanitizers: These devices use ultraviolet light to kill bacteria and fungi. They can be effective but vary in power and coverage. Follow the manufacturer's instructions carefully.
Freezing: Placing shoes in a freezer for an extended period (e.g., overnight or for 24-48 hours) may kill some fungus, but this method is not always reliable.
Sunlight: The sun's ultraviolet rays can kill some fungi. Place shoes in direct sunlight for several hours. This is more of a preventative measure than a guaranteed solution.

Killing the existing fungus is just the first step. Prevention is crucial to avoid recurrence.

Allow Shoes to Dry Completely: Fungus thrives in moist environments. Avoid wearing the same pair of shoes two days in a row. Allow them to air dry completely between uses. Stuffing them with newspaper can help absorb moisture.
Wear Moisture-Wicking Socks: These socks help keep your feet dry, reducing the moisture inside your shoes.
Use Shoe Inserts: Absorbent shoe inserts can help wick away sweat. Replace them regularly. Consider antifungal inserts.
Proper Foot Hygiene: Wash your feet daily with soap and water and dry them thoroughly, especially between the toes. Consider using an antifungal foot powder.
Disinfect Regularly: Even if you don't see fungus, regularly disinfecting your shoes is a good preventative measure.

Fungus in shoes can lead to:

Athlete's Foot: A common fungal infection that causes itching, burning, and cracking of the skin on the feet.
Toenail Fungus (Onychomycosis): A more stubborn infection that can cause thickening, discoloration, and crumbling of the toenails.
Foot Odor: Fungus contributes to unpleasant foot odor.
Spreading Infection: The fungus can spread to other parts of the body or to other people.

By taking steps to kill and prevent fungus in shoes, you can protect your foot health and avoid these problems.
