Cracked Heel Plasters: What to Know

A suitable plaster reduces contact between the fissure and footwear, which may make walking more comfortable while the surface repairs. It is a protective covering, not proof that the crack is healing and not a treatment for fungal infection. If the skin around it is scaly or itchy, Athlete's Foot may need separate attention. Adhesive can irritate sensitive skin, and a sealed covering can become damp if the foot sweats, so the skin needs regular checking.

Clean and dry the area before applying a plaster, then choose one large enough to protect the fissure without stretching the skin. Change it when wet, dirty, loose, or irritating. Stop using it if a rash develops around the adhesive. Do not apply medicated corn or callus products to an open crack. For surrounding intact Dry Skin, a bland moisturiser or Emollient Therapy may help, but keep greasy products away from adhesive edges so the covering stays in place.

Have the heel assessed if the crack is deep, repeatedly reopens, or remains painful despite reducing friction. Seek prompt care for increasing redness, warmth, swelling, pus, bleeding that will not settle, fever, or difficulty walking. Ask for early guidance about any open foot wound if you have diabetes, poor circulation, reduced sensation, or a condition that affects healing.

Ask which dressing suits the depth and location of the fissure, how often to change it, and whether the adhesive is likely to irritate you. Ask whether the heel needs treatment for fungal disease or thick dry skin, and how to combine protection with moisturising once the wound is closed.
