What Causes Itchy Feet?

The appearance of the skin and the location of the itch provide useful clues, but several causes can look similar. Itching between the toes with scaling or peeling often fits a fungal infection. A rash that follows contact with a new shoe, sock, detergent, or foot product may reflect irritation or allergy. Tiny, very itchy blisters along the sides or soles can occur with dyshidrotic eczema.

Athlete's foot commonly affects the spaces between the toes and may cause scaling, cracking, burning, or a damp-looking rash. It can spread to the soles and sides of the feet. A fungal infection is more likely when the skin is scaly and the itch is concentrated in toe webs, especially after the feet stay warm or sweaty.

Contact dermatitis can cause redness, dryness, swelling, stinging, or itch where the skin has touched an irritant or allergen. New footwear materials, adhesives, rubber, dyes, and fragranced products can be triggers. Dyshidrotic eczema may produce clusters of deep-seated blisters, followed by peeling or soreness as the skin heals. Dry, cracked skin can itch without an obvious infection, particularly after frequent washing or exposure to dry air.

For an overview of the symptom and its possible patterns, see [Itchy Feet](/symptoms/foot-itching/). More specific information is available about [Athlete's Foot](/conditions/athletes-foot/), [Contact Dermatitis](/conditions/contact-dermatitis/), and [Dyshidrotic Eczema](/conditions/dyshidrotic-eczema/).

Keep the feet clean and dry, including carefully drying between the toes. Change damp socks, choose breathable footwear, and avoid scratching, which can break the skin and allow bacteria to enter. Use a plain, fragrance-free moisturiser on dry areas, but avoid putting thick moisturiser between the toes when that area is moist or peeling.

If the pattern suggests athlete's foot, a pharmacist or clinician can advise whether a topical antifungal is suitable and how to use it. Read more about [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). Avoid sharing towels, socks, or shoes while a fungal infection is possible, and wash items that contact the affected skin.

Arrange a clinical assessment if the cause is unclear, the rash keeps returning, or symptoms do not settle with appropriate self-care. A clinician may examine the skin and, when needed, test a scale sample before recommending treatment.

Seek prompt medical advice if the foot becomes increasingly painful, hot, swollen, or rapidly red, or if pus, spreading redness, or fever develops. These changes can signal a bacterial infection requiring assessment.

Arrange medical care sooner if you have diabetes, reduced feeling in the feet, poor circulation, or a weakened immune system. Get urgent help for severe swelling, sudden colour change, or difficulty walking. A persistent itch without a visible rash also deserves an assessment when it is disrupting sleep or daily activities.

You could ask: Which cause best matches the location and appearance of my rash? Could a shoe, sock, detergent, or foot product be triggering it? Do I need a skin sample or a different treatment? How should I protect cracked or blistered skin while it heals? What changes should prompt me to return?
