Itching in feet in winter

Cold, dry air and indoor heating can remove moisture from the skin. Thick socks and closed shoes trap heat and sweat, while friction or a new material can provoke contact dermatitis. Fine cracks on heels and soles favour irritation. Peeling or scaling between toes may suggest a fungal infection, and sharply bordered scaly plaques can occur with psoriasis. Itching that spreads beyond the feet or affects family members needs a broader assessment.

Wash with lukewarm water, dry carefully between the toes, and apply a fragrance-free emollient to dry areas twice daily. Keep moisturiser off soggy skin between toes, change damp socks, choose breathable footwear, and avoid abrasive scrubs. Do not scratch cracks or use leftover prescription creams. If a product or shoe seems related, stop it temporarily and note whether symptoms improve.

Seek prompt care for increasing warmth, redness, swelling, pus, fever, severe fissures, or pain that makes walking difficult. People with diabetes, reduced sensation, or poor circulation should have new cracks or sores assessed early. Arrange review when scaling persists, nails change, the rash spreads, or moisturising does not help, because fungal infection, eczema, and psoriasis require different treatment.

Is this mainly winter dryness, shoe irritation, eczema, fungal infection, or psoriasis? Should the skin or nails be tested? Which emollient and treatment are safe for my medical conditions?
