What should you know about sweaty, cracked feet?

Moisture can soften the outer skin, and repeated rubbing from socks or shoes can then create fissures. Once the skin barrier is open, stinging and tenderness may follow. Peeling, itch or scaling between the toes or across the sole can occur with Athlete's Foot. Excessive Sweating may keep the area damp and make healing harder, but cracking is not explained by sweat alone. Dry skin, eczema, pressure and poorly fitting footwear can also contribute. The location, appearance and duration of the cracks help a clinician choose the right care.

Wash gently, dry between the toes, and avoid vigorous scrubbing or picking at loose skin. Wear clean breathable socks and shoes with enough room, and change them when damp. Protect shallow cracks with a suitable bland moisturiser or barrier product, keeping products between the toes only when advised because excess moisture there may worsen problems. A clinician may recommend a Prescription Antiperspirant or Iontophoresis for troublesome sweating once the skin is safe to treat. Do not use irritating products on open, bleeding or inflamed cracks without medical guidance.

Arrange an assessment when cracks do not improve, keep reopening, bleed, itch intensely or spread. Prompt care is needed for increasing pain, warmth, swelling, pus, red streaks, fever or difficulty walking. If you have diabetes, reduced foot sensation or circulation problems, seek advice early for any break in the skin. Sudden heavy sweating with fainting, chest discomfort, severe breathlessness or confusion also requires urgent attention.

Ask whether the cracks look fungal, irritant or pressure-related; which moisturiser is safe; how to keep the area dry; and when an antiperspirant or device treatment can begin. Show any products already used and describe footwear, exercise and recurrence.
