Gore-Tex in running shoes. The water will get in at the top of the shoe (as it is only 3cm high), and never get out, since Gore-Tex is watertight. Besides, when running, my feet sweat, so water will end up inside the shoe even if it isn't wet outside.

Actually, Gore-Tex has some fairly magical properties that make it both waterproof yet breathable (read as lets water out). According to their website ( http://www.gore-tex.com/remote/Satellite/toc/Techn ologyOfComfortFrameset/index ) The pores in Gore-Tex material is 20,000 times smaller than a drop of water keeping the water out, yet 700 times larger than a water vapor molecule, allowing sweat to escape. What this means for you is that you're still going to have wet feet while you run, but you can tell all your friends you have Gore-Tex running shoes.
