Summarize this article in one sentence.
Since the athlete's foot fungus is infectious, create a barrier between your feet and a potential vector for transmission. Never walk barefoot in public places, especially areas that tend to be warm and damp. Always dry feet off completely after bathing or swimming before putting your shoes back on. Air-dry shoes for 24 hours at minimum before wearing them again. The fungus can live for a time inside your shoes, so you definitely don't want to keep re-infecting yourself. To make sure that your shoes don't become vectors for infection, wear one set of shoes one day and another set the next. Buy new shoes if you have to. Anything that you use on your feet while infected must be disinfected with bleach or another cleaner. This includes nail tools, shoes, socks and anything else that has touched your feet. The last thing you want is to re-infect your feet after you have spent so much time trying to treat them. You should use very hot water and bleach to kill athlete's foot fungi in clothing and shoes. Tight shoes do not allow air to flow around your feet. This can make it easy for fungus to grow. Something else you can do is to use lamb's wool between your toes to keep them separated when wearing your shoes. Lamb's wool can be found in your local drug store of foot care center.

Summary:
Wear sandals or flip-flops when at a public pool or shower. Alternate your shoes every day. Disinfect clothes, tools and shoes. Wear wider shoes.
