A heat pack for warming the heel of an infant with a front panel and a rear panel wherein the rear panel is adapted for placement on the infant's heel and has an outer layer formed of a nonwoven material which may be wetted. A band is provided for attaching the heat pack to the infant's heel. Heat from the heat pack effectively drives water applied to the nonwoven material into the infant's heel where it is then trapped in the skin under the heat pack. By thus moisturizing and softening the skin, a puncture necessary for taking a blood sample is eased.
