While reading this question, another one came to my mind:

Last summer on a mountain hut some guy told my packing newspaper in Gore-Tex (or any similar) shoes wouldn't be good for their breathability.

The explanation seemed to be plausible: Because Gore-Tex is working like a funnel (cone) letting steam out, but no water in, there is a 'working direction'.

If you put newspaper in your shoes, the newspaper would suck the moisture. BUT from outside to inside. So obviously the opposite direction of the Gore-Tex 'working direction'. This guy said it's like pressing water from the wrong side through a funnel and this could (or would) harm the effect of the Gore-Tex.

But everywhere you go, people plug newspaper in there shoes to dry them faster.

So was this guy right or wrong? Does plugging boots with newspaper kill their Gore-Tex effect?

My first thougt was, maybe the newspaper is only sucking the moisture from inside the Gore-Tex layer?
