What's up with goretex running shoes?

Inov-8 has just announced new fall 09 running shoes, including a lighter f-lite, which I'd like for roads. But what's up with the 275 GTX and 345 GTX? Why goretex in a running shoe? Goretex isn't going to stop water from entering from above - either from rain or any respectable sized puddle. But inov-8 also has goretex gaiters. Does this combination work in deep puddles or streams? The major problem that I see is getting the sock wet in winter from a deep puddle or stream crossing and then the goretex not allowing the sock to dry quickly (remember its made to keep water from crossing it). Ouch. Are there reviews of the gtx system that are especially relevant to cold and real water, from a real user?
