What should you know about overly sweaty feet?

Sweat keeps skin cool, but excessive moisture on the soles can leave socks damp, cause odor, and make the skin white or wrinkled. Moisture between the toes can also make the outer skin easier to irritate. Athlete's Foot may cause itching, scaling, cracking or burning, so a foot rash should not be assumed to be caused by sweating alone.

Some people sweat more from both feet without another illness; this pattern is often called plantar hyperhidrosis. A clinician may ask when sweating began, whether it happens during sleep, and whether medicines or other symptoms appeared at the same time.

Wash and dry the feet carefully, especially between the toes. Change socks when they become damp, choose breathable footwear, and rotate shoes so each pair can dry fully. Avoid sharing towels or shoes, and treat scaling or cracks with professional guidance.

A clinician may recommend a Prescription Antiperspirant for the soles. Iontophoresis is another option that uses a mild electrical current through water to reduce sweat activity over a course of treatments. The right choice depends on your skin condition, health history and how much sweating interferes with life.

Arrange a medical assessment if sweating begins suddenly, affects only one foot, occurs heavily during sleep, or comes with fever, weight change, dizziness, chest symptoms or a new medicine. Seek prompt care for spreading redness, warmth, swelling, pus, deep cracks, severe pain or difficulty walking. These features can signal infection or another problem needing treatment.

Ask whether the pattern fits plantar hyperhidrosis, whether a rash needs testing, and which option is suitable for your skin. You can also ask how to apply an antiperspirant safely, how often iontophoresis is used, and what changes should prompt a review.
