What should you know about petroleum jelly for feet?

Heel skin is exposed to pressure, friction, and repeated drying. Petroleum jelly creates an occlusive layer that slows water loss, making thick, rough skin more flexible and reducing strain on small fissures. It works best when applied to clean, slightly damp skin.

A foot problem can have another cause. Peeling or itching between the toes, scaling along the sole, or a recurring rash may fit [Athlete's Foot](/conditions/athletes-foot/) and needs an antifungal plan rather than moisturiser alone.

Wash gently, dry carefully between the toes, and apply a thin layer to the heels and other dry areas. Put on clean socks if the ointment feels slippery, and avoid walking barefoot on smooth floors. Do not seal petroleum jelly over wet, draining, or visibly infected skin.

For ongoing [Dry Skin](/symptoms/dry-skin/) or [Cracked Skin](/symptoms/skin-cracking/), a clinician may recommend [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) with a product suited to the thickness and location of the affected skin.

Seek medical advice for deep or bleeding fissures, increasing warmth, swelling, pus, spreading redness, fever, or pain that makes walking difficult. People with diabetes, reduced sensation, or poor circulation should have foot cracks assessed early rather than managing them alone.

Ask whether the cracks are caused by dryness, pressure, eczema, or fungus; whether a medicated product is needed; and how to protect the area while it heals without trapping moisture between the toes.
