★★★★☆
When you come home from work, wearing sandals is a much better option, or if it's colder a clean pair of sox & slippers.
Most fungi, including AF fungus, can be killed with 140* hot water, so if you've been running around barefoot in your home all your floors are infected, & you need to get a floor steamer (steam is created at 212*) & run it over every square inch of your floors to kill the AF fungus, so you're not reinfecting yourself, or anyone else.
Just wish it was this easy to kill the AF fungus on my feet.
