You can cleanse yourself from top to bottom, especially the feet. Make a powder or oil for prosperity, a simple one is a pinch of cinnamon, a pinch of sugar, and a bit of cloves mixed in a base of baby powder, sprinkle this from bottom to top, starting with your feet, and up to the crown of your head. You can then take some salt and pepper and sprinkle it a bit on your feet up to the top of your head for protection.
This is called a cleansing and dusting. Another option is to just sprinkle to powders on the feet, or using lotion or oils instead.
This is just the basic idea, not any added steps or "something extra".
