Athlete's foot

I have tried everything the doctors gave me, no results. I know I'm supposed to keep my feet dry but, come on, in the winter? It's almost impossible...or maybe it's just me, but I'm having a hard time. And I don't want to pee on my feet either...but I want to be rid of it for good.
Any tips please?
Thanks a bunch!

Yeast can be very stubborn. Keep on applying the antifungal cream, and dont wear synthetic socks, pure cotton while you're trying to make your feet not sweat. At night, hope you're airing them out

Tinactin and Desitin are creams available for athlete's foot. Perhaps Zincofax could work as a preventative, the stuff for baby's diaper rash, to treat your feet with socks on since the cost and your activities may limit your ability to find effectiveness.
