this is a very common problem. when your foot is wet and you go into an environment where it's likely that there is some fungus everywhere on the floor it's very hard to avoid. so the first and the most important thing is to try to wear either flip-flops or water shoes when walking as opposed to going barefoot around the pool or the locker room shower. to treat it you can use over-the-counter antifungals to help knock the foot fungus out. if that doesn't work then you can see a dermatologist who can even give you a prescription medication; either a cream or even a pill to help clear it. some people are more prone to foot fungus than others. so once you have it you might be prone to getting it again over time. there is also a powder that you can put into your shoe that's very absorbent that helps prevent water from accumulating which -- that water moisture and dark occluded environment is just ideal for that fungus to grow. so you want to create an environment that's not so fungus friendly and also treat the underlying cause and hopefully that will help keep it at bay for a long time.
