What should you know about feet itching underneath?

Look at the sole, heel, and spaces between the toes. Fine scaling or cracks can occur when the skin barrier is dry or irritated. Redness, swelling, or a rash after a new soap, shoe, sock, foot product, or cleaning chemical can fit contact dermatitis. Recurrent itchy, thickened patches may occur with atopic dermatitis, psoriasis, or asteatotic eczema.

Moist, peeling, or macerated skin between the toes can occur with a skin yeast infection. Scabies may cause intense itching with small bumps and can affect other household members, while hives tend to form raised, transient welts. Lichen planus can produce itchy, purplish or scaly areas. These patterns overlap, so the itch alone cannot identify the cause.

Wash gently with lukewarm water, pat dry—especially between the toes—and apply a plain, fragrance-free moisturiser to dry areas. Change damp socks, choose breathable footwear, and avoid scratching, harsh scrubs, and newly introduced foot products until the skin settles. Keep any cracked areas clean and protected from friction.

If the itch began after a product or pair of shoes, stop that suspected trigger and note whether the rash changes. Do not apply steroid, antifungal, or other medicated creams to an undiagnosed rash without checking the label or asking a pharmacist or clinician, because the wrong product can mask or aggravate some conditions.

Arrange a clinical assessment if the itch is persistent, keeps returning, spreads, disrupts sleep, or comes with scaling that does not improve with gentle skin care. Prompt care is appropriate for increasing warmth, swelling, pain, pus, rapidly spreading redness, deep cracks, or fever. Seek urgent help for facial swelling, breathing difficulty, or a widespread rash with feeling faint.

People with diabetes, reduced sensation, poor circulation, or a weakened immune system should have foot skin changes assessed sooner, because small cracks or infections may need specific care.

Ask: Does the pattern look more like irritation, eczema, psoriasis, or an infection? Should the skin between my toes be tested? Which moisturiser or medicine is suitable for the exact area? Could a product, shoe material, or medication be contributing? What changes would mean I should return promptly?
