Does any one have the Lowa Tibet Boots?

It is not loose. A two layer material is apparently bonded to the membrane. As i have always understood it, there are two typical ways to construct a boot with a Gore-Tex membrane. The european way and the american way. One uses a complete sock and the other uses a top piece sewn onto the footbed, so that the membrane doesn't cover the footbed. I can't recall which does which. It looks like Lowa have their factories in europe. You would need to research them a little further. Note the goretex membrane is white, thin (plumbers tape PTFE) It has to be bonded to something.

what i've seen in boots, the gore tex is just a sock membrane with a knitted open nylon tricot covering on either side of the gore tex, the same as the inside of a three layer rainshell but without the nylon outer face fabrcic, that isnt bonded to anything else. its loose from the inner boot lining and the outer boot fabric. outdry was another type of membrane that is bonded to the boot material, not sure if its bonded to the outer or inner.
