I wear Seal mask type goggles specifically made for triathlon. They don't fog badly, sometimes worse than others. They have fantastic peripheral visibility (??). Mine are tinted and I can see perfectly fine indoors.
I'm with Grog on the antifog stuff. I've used spit in the past and also a very diluted dish detergent to soak them in periodically. It seems to help.
