Nail Fungus vs. Athlete’s Foot: What's the Difference?

Fungal infections on the feet are incredibly common—but they don’t all look or behave the same. If you're experiencing itchy, discolored, or damaged skin or nails, you might be wondering: Is it nail fungus or athlete’s foot? While both conditions are caused by fungi and can even occur at the same time, they are not the same thing. Understanding the differences is key to choosing the right treatment and preventing a recurrence.

What Is Nail Fungus?

Nail fungus, or onychomycosis, is a fungal infection that affects the fingernails or toenails. It usually starts beneath the nail plate and grows deeper into the nail bed.

Common symptoms of nail fungus:

  • Yellow, brown, or white discoloration

  • Thickened or brittle nails

  • Crumbly or ragged nail edges

  • Foul odor

  • Nail separating from the nail bed (onycholysis)

  • Pain or pressure in the affected toe

Nail fungus tends to develop slowly and is often harder to treat because the fungus hides under the protective nail.

What Is Athlete’s Foot?

Athlete’s foot, or tinea pedis, is a fungal skin infection that typically affects the soles of the feet, toes, and in between the toes. It's contagious and thrives in warm, moist environments like gyms, locker rooms, and shared showers.

Common symptoms of athlete’s foot:

  • Red, scaly, or peeling skin

  • Itching, stinging, or burning

  • Cracked or blistered skin between the toes

  • Odor or excessive moisture

  • White, soggy patches of skin

Athlete’s foot spreads more easily than nail fungus and can even lead to nail infections if left untreated.

Key Differences at a Glance

Feature Nail Fungus Athlete’s Foot
Location Nails (mostly toenails) Skin (especially between toes)
Symptoms Thick, discolored, brittle nails Red, itchy, scaly or peeling skin
Spread Slower, harder to eliminate Contagious, spreads quickly
Appearance Nail distortion, odor Rash-like, possibly cracked skin
Pain Sometimes Often itchy or burning

Can You Have Both at the Same Time?

Yes, and it’s actually quite common. Because both infections are caused by similar fungi, athlete’s foot can spread to the toenails, and vice versa. If you’re treating one, it’s important to monitor for signs of the other.

How to Treat Each Condition

Nail Fungus:

  • Topical antifungal oils (tea tree, oregano, clove)

  • Prescription antifungals (oral or topical)

  • Laser therapy or nail removal in severe cases

Athlete’s Foot:

  • Antifungal creams or sprays (clotrimazole, terbinafine)

  • Keep feet clean and dry

  • Change socks daily and avoid tight shoes

Prevention Tips for Both

  • Wear shower shoes in public places

  • Wash and dry feet thoroughly every day

  • Use antifungal powder or spray if you're prone to infections

  • Avoid sharing shoes, socks, or nail tools

  • Let shoes dry out between wears

Final Thoughts

While nail fungus and athlete’s foot are both caused by fungi, they affect different areas and require different treatment approaches. Knowing the difference helps you take fast, targeted action—so you can clear the infection and keep your feet healthy for the long haul.

If you're unsure which one you have, it's always a good idea to check in with a doctor or podiatrist for a proper diagnosis.
