Mix 1 cup white vinegar and 2 gallons warm water together and a few drops of essential oil. Soak your feet for 45 minutes in this mixture. Now use a pumice stone to remove the skin from heels and callused areas of your feet. Take a soft brush and rub your upper foot area and toes. Doing this once or twice a week, followed by application of a moisturizer is sure to help you have soft and supple feet. This is one of the best solution for smelly feet and nail fungus. Make sure that you do not use the same solution more than once.
