most of the water that gets into am40s biking shoes has got in through the same hole your foot went through.
i really don't think goretex would help very much, but maybe gaitors might...?
anyway, the lace-flap on am40's is ace, i don't care if it looks weird, it keeps all sorts of crap off my laces.
laces are horrible when it's cold wet and muddy, and you're struggling to undo a wet muddy double-knot because your hands are cold and your finger nails have gone soft.
am40's: single knot, not very tight, close the flap, done.
