For Baby-Soft Heels: Rub shaving cream on your feet. Soak a handtowel in a solution of equal parts warm water and Listerine. Wrap the towel around your feet and let it sit for 30 minutes. After 30 minutes, use the towel to rub your feet. Some of the calloused and discolored skin will rub off. Last step: Apply a healthy amount of lotion to your feet. Don't do this more than once a week!
