What should I do to nurse away my athlete's foot fungus quicker?

I already have over-the-counter prescription cream and sprays which I applied to my shoes to kill fungus in there. I apply the cream after washing my feet thoroughly, am always in socks. Tomorrow I have a swim meet and when it is almost my event we have to step under a special tent thing that has a large puddle of warm water under it; a great place for it to spread. What shall I do then? Stand on my flip flops or something?
