What Should You Know About Pitted Keratolysis on Toes?

This condition affects the outer layer of skin, commonly on weight-bearing parts of the toes and soles. Small crater-like pits may look more obvious after the skin has been wet. The area can feel soft, soggy, or mildly tender, and a strong smell may remain even after washing. Heat, sweating, tight footwear, and shoes that do not dry fully can support the bacteria involved. It is not the same as a deep wound, but another foot problem can look similar, so appearance alone cannot confirm the diagnosis.

Wash the feet gently, dry carefully between the toes, and change damp socks promptly. Rotate shoes so each pair can dry completely; breathable footwear may reduce trapped moisture. Avoid scraping the pits or applying harsh household products, which can irritate broken or softened skin. A clinician may recommend a topical antibacterial medicine, and an antiperspirant may be useful when excessive sweating keeps returning. Use products on intact skin as directed and stop if marked irritation develops.

Arrange a medical assessment if the pits or odour persist despite careful drying, return repeatedly, or make walking uncomfortable. Seek prompt care for spreading redness, increasing warmth, swelling, drainage, significant pain, fever, or a wound that is not healing. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should seek advice early about any foot skin change. A clinician can distinguish pitted keratolysis from fungal infection, eczema, or an ulcer and choose treatment accordingly.

Ask whether the pits and odour fit pitted keratolysis or another condition, whether you need a prescription topical antibiotic, and how to control foot sweating. You can also ask how to clean or protect footwear, when improvement should be reviewed, and which symptoms would require earlier follow-up.
