How to Treat and Prevent Athlete's Foot

What athlete's foot is and how to spot it

Athlete's foot is a fungal infection of the skin, usually between the toes or on the soles of the feet. It causes itching, burning, cracking, and sometimes blistering. The skin may turn red, white, or scaly. You don't have to be an athlete to get it—the fungus thrives in warm, moist places like locker rooms, public pools, and the inside of shoes.

The infection spreads through direct contact with the fungus or by walking barefoot on contaminated surfaces. It's contagious and can spread to other parts of your body or to other people if you scratch the area and then touch elsewhere. Some people are more prone to it than others, especially if they have a weakened immune system, diabetes, or a history of fungal infections.

Key Takeaways

• Athlete's foot causes itching, burning, and scaling between the toes or on the soles, and spreads through contact with the fungus in warm, moist environments.
• Over-the-counter antifungal creams, sprays, and powders can treat mild cases, but severe or persistent infections may need a prescription from a doctor.
• Keeping feet dry, wearing breathable shoes, and avoiding barefoot walking in public spaces are the most effective ways to prevent infection.
• If you have diabetes, a weakened immune system, or the infection doesn't improve after two weeks of treatment, see a healthcare provider.

Over-the-counter treatments you can buy

Most cases of athlete's foot respond to antifungal products sold without a prescription. These come as creams, sprays, powders, and solutions. Common active ingredients include tolnaftate, miconazole, clotrimazole, and terbinafine. You'll find these at drugstores, supermarkets, and shoe stores throughout South Carolina.

Apply the product to clean, dry skin according to the package directions—usually once or twice daily for two to four weeks. Continue using it even after the visible symptoms disappear, because the fungus can linger. Powders work well for prevention and for keeping feet dry during treatment. Creams and solutions penetrate better for active infections between the toes.

If the infection covers a large area, involves the toenails, or doesn't improve after two weeks of treatment, stop using over-the-counter products and see a doctor. Severe cases need prescription-strength antifungals or oral medication.

When to see a doctor

Contact a healthcare provider if the infection spreads to your toenails, covers a large area of your foot, or causes severe pain or swelling. You should also see a doctor if you have diabetes, a weakened immune system, or if over-the-counter treatment hasn't worked after two weeks.

A doctor can prescribe stronger topical antifungals, oral antifungal medication, or both depending on how severe the infection is. They can also rule out other skin conditions that look similar, like eczema or psoriasis. In South Carolina, you can start with your primary care doctor or see a dermatologist for skin conditions.

How to prevent athlete's foot

Keep your feet dry, especially between the toes. Dry them thoroughly after bathing, swimming, or sweating. Wear breathable shoes and moisture-wicking socks, and change socks if they become damp. Avoid walking barefoot in locker rooms, public showers, pools, and communal changing areas—wear shower shoes or flip-flops instead.

Don't share towels, nail clippers, or shoes with others. Wash your feet daily with soap and water, and trim toenails straight across and short. If you frequent gyms or pools, bring your own towel and wear protective footwear. At home, keep bathroom floors clean and dry, and avoid sharing bathmats.

If you're prone to athlete's foot, use an antifungal powder or spray on your feet and inside your shoes as a preventive measure, especially during warm, humid months in South Carolina.

Shoe choices that reduce your risk

Shoes that trap moisture and heat make fungal infections more likely. Choose shoes made of breathable materials like mesh, canvas, or leather that allow air circulation. Avoid tight shoes that create a warm, moist environment. Sandals and open-toe shoes are good choices in warm weather.

Rotate your shoes so each pair has time to dry out completely between wearings. If your shoes get wet or sweaty, remove the insoles and let them air dry separately. Some people benefit from antifungal shoe inserts or sprays designed to kill fungus inside the shoe. Athletic shoes with moisture-wicking linings are better than rubber-soled shoes that trap sweat.

What to do if it keeps coming back

Recurrent athlete's foot often means the fungus wasn't completely eliminated or you're being reinfected. Make sure you're using treatment for the full recommended time, even after symptoms disappear. Check that your shoes and socks are truly dry before wearing them, and consider replacing old shoes that may harbor fungus in the insoles or seams.

If you live with others, make sure they're not passing the infection back to you. Clean shared bathroom surfaces with a disinfectant, and don't share towels or nail tools. If recurrence continues despite these steps, see a doctor—you may need prescription treatment or have a different condition that looks like athlete's foot.

Frequently Asked Questions

Can I catch athlete's foot from trying on shoes in a store?

The risk is low if you wear socks while trying on shoes and don't have cuts or cracks in your skin. The fungus needs direct contact with broken skin or a warm, moist environment to spread. Wearing socks and keeping your feet dry during shopping reduces risk significantly. If you're concerned, wash your feet when you get home.

Is athlete's foot the same as jock itch?

Both are caused by similar fungi, but jock itch occurs in the groin area while athlete's foot affects the feet. They spread the same way and are treated with similar antifungal products. However, the skin in the groin is more sensitive, so treatments may differ. If you have both, treat them separately and wash your hands between touching each area.

How long does it take to get rid of athlete's foot?

Mild cases usually improve within one to two weeks of treatment, but you should continue applying the antifungal for the full recommended time—often two to four weeks—to prevent recurrence. Severe cases or infections involving the toenails can take six weeks or longer. If there's no improvement after two weeks, see a doctor.

Can I exercise or go to the gym while I have athlete's foot?

Yes, but take precautions to avoid spreading it. Wear clean socks and shoes, bring your own towel, and wear shower shoes in the locker room and shower. Wash your feet and dry them thoroughly after exercising. Avoid barefoot activities like yoga or martial arts until the infection clears, and let others know so they can protect themselves.

Will athlete's foot go away on its own?

Athlete's foot rarely clears without treatment. The fungus can persist for months or years if left untreated, and it may spread to other areas or to other people. Over-the-counter antifungals are inexpensive and effective for most cases, so treatment is worth starting as soon as you notice symptoms.
