Cracked heels can develop when the skin becomes very dry, rough, or irritated due to cold weather, walking barefoot, early morning moisture exposure, dehydration, friction, or prolonged standing. The skin around the heels may become thick, painful, flaky, or split deeply if dryness continues for a long time. Moisturising and healing ointments containing urea, lactic acid, petroleum jelly, or thick emollients may help soften dry skin and improve cracked heels gradually. Applying the ointment regularly at night and wearing soft cotton socks afterwards may help retain moisture and support healing. Warm water foot soaking, gentle removal of dead skin, proper hydration, and avoiding barefoot walking may also help reduce dryness and cracking. Comfortable footwear with proper cushioning may further protect the heels from repeated friction. Consult your doctor if the cracks become very deep, bleed, develop swelling, pus, severe pain, or if you have diabetes, because foot infections may require prompt treatment and closer care.
