Causes of Pitted Keratolysis

The small depressions usually appear on weight-bearing areas of the soles, especially where sweat and pressure collect. A strong foot odour may occur because bacterial activity produces smelly compounds. Prolonged use of closed footwear, heavy sweating, damp socks, and limited airflow can maintain the moisture that bacteria need. The pits may be easier to see when the skin is wet. It is an infection of the skin surface, not simply a hygiene failure.

Wash the feet and dry carefully between the toes and across the soles. Change damp socks, rotate footwear, allow shoes to air, and choose breathable options when possible. A clinician may prescribe Topical Antibiotic Therapy to reduce the bacteria. Prescription Antiperspirant may help when excessive sweating keeps returning, but it should be used according to medical advice and may irritate cracked skin.

Arrange an examination if pits, odour, tenderness, or peeling persist despite keeping the feet dry, because fungal infection, eczema, or another problem can look similar. Seek prompt care for spreading redness, increasing warmth, swelling, drainage, fever, or difficulty walking. People with diabetes, reduced sensation, or poor circulation should have foot changes assessed early.
