Can sweaty feet cause pitted keratolysis?

Pitted keratolysis is a superficial bacterial infection affecting the thick skin of the soles. Tiny crater-like pits may appear on weight-bearing areas, and the feet can have a strong smell. Plantar hyperhidrosis does not itself create the pits, but persistent moisture softens the outer skin and makes conditions more suitable for the bacteria. Wearing closed shoes for long periods can trap additional heat and sweat. Similar-looking changes may come from other foot problems, so appearance alone cannot confirm the diagnosis.

Wash the feet gently, dry carefully between the toes and across the soles, and change damp socks promptly. Choose breathable footwear and alternate pairs so shoes can dry fully. Avoid harsh scrubbing, picking at pits or sharing towels. A clinician may recommend a topical antibacterial treatment and a plan to reduce sweating; use products on the soles only as directed, especially if the skin is cracked. Treating moisture and infection together helps reduce recurrence.

Arrange an assessment if pits, odor or softened sole skin persist after careful drying, or if the diagnosis is uncertain. Seek prompt care for spreading redness, warmth, swelling, drainage, marked pain, fever or difficulty walking. People with diabetes, reduced foot sensation or poor circulation should have new foot changes assessed early rather than self-treating for a prolonged period.

Could these pits be pitted keratolysis or another foot condition? Is there a safe way to reduce sweating on my soles? How long should treatment be used, and what should I do if the odor or pits return?
