Many months: You can spray the shoes with an antifungal spray and let the dry. There is also a device that uses a spectrum of uv light to kill the fungus. The device is placed into the shoes.

Can last for a while: Fungus can hang around for a while. You reduce the amount by spraying the inside of the shoe with an antifungal spray after you have worn it. This will reduce the amount of fungal load in the shoe. If you sterilize a shoe it will unfortunately be unwearable.

Both: Walking into communal areas such as a pool might expose you to fungus that can invade the skin. Wearing shoes a lot in warmer weather can cause the feet to sweat a lot, creating a risk factor for athlete's foot as well.

A 29-year-old female asked:

I have athletes foot. Do I need to throw out shoes or is there a way to sanitize them? I have Lysol spray, is there a better product?

Maybe/not: The Lysol would be worthless. Look around for a foot fungus spray like Micotin (miconazole) or similar product. This can help your feed & may remove the fungus from the shoes. Only time will tell if the spray you use is effective but it is worth a try.
