What should you know about cure for pitted keratolysis?

Pitted keratolysis is a superficial bacterial infection affecting the pressure-bearing skin of the soles, especially when feet stay warm, damp, or enclosed for long periods. Small shallow pits may join together, and an unpleasant smell can be more noticeable than pain. The appearance can overlap with other foot conditions, so a clinician may check the skin before choosing treatment.

Sweat is not the infection itself, but persistent moisture softens the outer skin and creates a setting in which the bacteria can thrive. This is why clearing the infection and changing foot-care habits work together.

A clinician may prescribe a topical antibiotic therapy for the affected areas. Use it exactly as directed and complete the advised course. Washing, careful drying between the toes, rotating shoes, and choosing breathable socks can reduce dampness. Clean footwear and allow it to dry fully before wearing it again.

If sweating is a major contributor, ask about [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). For context on the smell that may accompany this condition, see [Body Odour](/symptoms/body-odour/), and read about [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/). Avoid scraping pits or sharing towels and footwear.

Book an assessment if pits, odour, peeling, or tenderness persist despite careful drying, or if the problem keeps returning. Seek prompt care when redness spreads, swelling becomes marked, pus develops, walking is painful, or you have diabetes or reduced sensation in the feet. These features can require a different or more urgent plan.

Are the pits consistent with pitted keratolysis or another infection? Which topical medicine should I use, for how long, and how can I manage sweating and footwear to prevent recurrence?
