What should you know about cracks and fissures on feet?

A fissure may occur at the heel, ball of the foot, toe tips, or between the toes. Pressure, friction, dry air, repeated wet-and-dry cycles, and unsuitable footwear can weaken the outer barrier. Atopic Dermatitis or Psoriasis can create inflamed, scaly skin that cracks more readily. Burning, itch, or peeling between toes may need a different assessment. Note whether the problem affects one or both feet, whether it bleeds, and what makes it worse; these details help separate mechanical splitting from an underlying skin disorder.

Clean with a mild cleanser and lukewarm water, then dry thoroughly without rubbing. Apply a bland, rich moisturiser to dry areas, avoiding product between the toes unless advised. Regular Emollient Therapy can support a damaged barrier. Use socks and shoes that reduce rubbing, and change damp socks promptly. Do not pour harsh antiseptics into a fissure or cut away hard skin yourself. If the crack is open, protect it with a clean dressing and monitor it for change.

Get prompt medical advice for spreading redness, warmth, swelling, pus, fever, red streaking, or pain that is worsening rather than settling. A fissure that is deep, repeatedly reopening, or preventing comfortable walking also merits review. People with diabetes, poor circulation, numbness, or immune suppression should seek advice early for any open foot crack. Do not wait for severe pain if sensation is reduced.

Does the location suggest Atopic Dermatitis, Psoriasis, friction, or another cause? What should I apply to the fissure and surrounding skin? How can I reduce pressure while it heals? Which changes require same-day advice?
