As mentioned by sORe-EyEz, Goretex is a water-proof fabric. For boots, it is used as a inner layer. When you cut up your Goretex boots, you should be able to see it (though I wouldn't advocate it
).
Using waterproof boots for winter wear is recommended for situations where snow falls onto your boots while walking (common) and when u enter a heated room, it melts and seeps into your shoes. Having wet socks/feet during winter is no joke. As for the slippery part, get a shoe/boots (waterproof or otherwise) with good soles. It can save your day.
I do have a Goretex boots that I use when I travel; however, its sole is Vibram (a brand) sole which I find its grip not that good. So when walking in winter, I have no problems with wet feet but must walk very carefully
. So, there is a reason for the many varying prices of shoes/boots etc...
