Put a handful of marbles in the foot basin or any large container to soak your feet in. Fill halfway with cold water. Warm enough whole milk to fill the basin and whisk until frothy. Add 1 Tbs. each of vanilla extract and chocolate extract. Soak feet for 5 minutes while you are rolling them over the marbles. The lactic acid in the milk naturally sloughs off dead skin and softens them. Next, mix a handful of each brown sugar and white sugar with enough olive oil to form a paste. Massage this paste into the feet, ankles, knees and calves. Rinse with warm water and pat dry. Finish with lotion that has been warmed in the microwave. You can add a few drops of vanilla extract in your lotion to keep the vanilla scent on your skin.
