I simply dont just get fungus thats not how it works. You need to have a open wounds, cracked or brittle skin or a damaged toe nail and then it take MONTH until it spread you have so much time to fix it. If you get visible feet fungus you have to be an absolute filthy animal to let it get that far. You literally have month to fix it before it gets bad and it only happens in the first place if you dont take care of your feet
