How to control sweaty feet

Sweaty feet may reflect plantar hyperhidrosis, where sweat production is excessive or occurs without obvious heat or exercise. Moisture trapped inside shoes softens the skin and can encourage odour, irritation, or athlete’s foot. Look for scaling, peeling, cracks, itching, or a rash between the toes. These features need different care from sweating alone, so avoid assuming that every damp foot has a fungal infection.

Wash and dry the feet thoroughly, especially between the toes. Change socks when damp and choose moisture-wicking or breathable materials; rotate shoes and let them dry fully before wearing them again. A prescription antiperspirant may reduce sweating when regular products are insufficient, but it can irritate broken skin. Iontophoresis is another option that uses a mild electrical current through water and should be planned with a trained clinician. Treat athlete’s foot if a clinician confirms it.

Arrange an assessment if sweating is new, severe, one-sided, associated with night sweats or other illness, or interfering with work, sleep, or walking. Seek prompt care for spreading redness, warmth, swelling, pus, deep cracks, fever, or a foot wound that is not healing. People with diabetes, reduced sensation, or circulation problems should seek advice early for any break in the skin.

Ask whether the pattern suggests plantar hyperhidrosis or athlete’s foot, how to apply prescription antiperspirant safely, and whether iontophoresis fits your health history. Discuss foot-care precautions if you have diabetes, eczema, reduced sensation, or circulation concerns.
