Clean the mud off after a game, then let them dry naturally with paper inside them.
If they're a particularly good fit, use shoe trees to maintain their shape.
Don't worry too much about dubbin/wax/polish etc unless they're leather. If they are, give 'em a good polish and use leather conditioner from time to time.
If they have removable studs, from time to time take the studs out, put a bit of vaseline on the threads, and re-fit. I've seen loads of boots (and golf shoes etc) wasted because a worn stud can't be removed because a thread has rusted.
Make sure you clean round the seam where the upper is attatched to the sole, an old toothbrush gets the mud out properly, and stops any rot/mould that sometimes occurs when dirt is left on a surface too long.
Oh aye, and don't pull the tongue up too high, and don't have the laces so tight that the sides are too close together, you'll pull the upper out of shape.
