What are the treatment options for sweaty feet?

Plantar hyperhidrosis means the soles sweat more than needed for cooling. Damp socks and shoes can lead to odour, softened skin, rubbing, and fungal or bacterial overgrowth. Sweating may affect both feet and can be longstanding, or it may appear with medicines, hormonal changes, illness, or sweating elsewhere. A clinician considers the pattern, timing, medications, and general health before choosing treatment.

A clinician may recommend [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) applied to completely dry soles, often at a scheduled time so irritation can be managed. [Iontophoresis](/treatments/laser-and-energy/iontophoresis/) uses a mild electrical current while the feet sit in water; treatment is repeated according to the device plan and then maintained when needed. Change damp socks, rotate shoes, allow footwear to dry fully, and use moisture-wicking materials. Avoid applying irritant products to cracked skin, and report burning or persistent redness.

Book an assessment if sweating begins suddenly, affects the whole body, happens during sleep, or comes with palpitations, weight change, fever, weakness, or dizziness. Seek prompt care for painful cracks, spreading redness, pus, or a rapidly worsening rash. Foot odour alone is not a diagnosis, so persistent symptoms deserve an examination.

Is the sweating limited to my feet or part of a wider pattern? Which antiperspirant strength and application schedule suit my skin? Is iontophoresis appropriate if I have sensitive or cracked skin? Could a medicine or health condition be contributing?
