Itching on the sole can be athlete’s foot (tinea pedis), but a dark patch is not specific for fungus. It can also be irritation/eczema or darkening left after scratching.
What you can try if the skin is scaly, peeling, cracking, or itchy:
  • Use an OTC antifungal such as terbinafine 1% cream. Apply a thin layer to the itchy area and between toes if involved, following the product label. Many terbinafine products are used once daily for 1 week, while other antifungals such as clotrimazole are often used twice daily for 2-4 weeks.
  • Continue for the full labelled course, even if itch improves. CDC treatment guidance supports topical antifungals for skin fungal infections.
  • Keep feet dry: wash, dry carefully especially between toes, change socks daily, air out shoes, and wear sandals in shared showers. CDC foot hygiene advice
  • Do not use a steroid-only cream such as hydrocortisone or betamethasone unless a clinician has examined it. Steroids can mask or worsen a fungal rash.
The darkness may fade slowly after the inflammation settles, but do not treat the pigment itself first.
See a clinician or dermatologist soon if the dark area is new or growing, has uneven borders or multiple colors, is painful, has an ulcer/wound, involves the nail, spreads despite treatment, or is not clearly improving after 2 weeks. Seek earlier care if you have diabetes, poor circulation, or reduced foot sensation. A clinician can examine it and do a simple fungal skin scraping if needed.

Tinea pedis means athlete’s foot, a fungal infection of the skin of the feet.

First-line treatment

Use an over-the-counter antifungal cream, applied to clean, completely dry skin:
  • Terbinafine 1%: commonly once or twice daily, depending on the product, for about 1 week
  • Alternatives: clotrimazole 1%, miconazole 2%, or butenafine. These often need 2-4 weeks.
Apply to the itchy/scaly area, between the toes, and 1-2 cm around it. Follow the exact package directions and complete the course even if itching improves. Skin antifungals are standard treatment for uncomplicated athlete's foot, as described by the CDC treatment guidance.

Foot care to prevent recurrence

  • Dry feet well, particularly between the toes.
  • Change socks daily, or more often if sweaty.
  • Use breathable shoes and alternate pairs to let them dry.
  • Antifungal foot powder can help keep feet dry.
  • Wear slippers/sandals in communal showers or pools.

Avoid

  • Do not use steroid-only creams or combination creams containing potent steroids unless prescribed after examination. They may worsen or hide fungal infection. The CDC cautions against steroid creams for suspected fungal rashes.

See a clinician if

  • Not clearly improving after 2 weeks of correct topical treatment
  • Severe cracking, pain, swelling, pus, or spreading redness
  • Toenails are thickened, yellow, or crumbly
  • You have diabetes, poor circulation, or reduced sensation in the feet
  • The dark patch on the sole is enlarging, irregular, multi-colored, bleeding, or not clearly part of a scaly rash. It needs examination rather than assuming it is fungal.
