Make a mixture of 1 cup vinegar and enough water to soak your feet in. Soak for 15 minutes. Then, dry with paper towels.
Add more baking soda to the water and soak your feet for another 15 minutes. Then, again dry your feet with paper towels.
Do this twice a day. The fungi will be destroyed by the vinegar, and baking soda will inhibit the growth of more.
