Brasher Supalite GTX II boots here. Gore-tex, full grain leather. Bone dry. First test was submersing them in a bucket of water for 5 minutes with tissue paper stuffed in them. No problem. Not even at the shoe lace points.

£100. Best shoes I have ever had. They fit properly from day one, like it's moulded to my foot. They are super light as well, as light as trainers. 1160g per pair (for size 9). Downside is that they are not as warm as others, but that can easily fixed by thermal socks. The plus side is that you can use them in summer as well.
It's not Gore-tex, it's the quality of the trainers. You really need full grain leather boots. You need to look after them as well by regularly cleaning them and rubbing leather grease in them.
All waterproof membranes will eventually fail because they are constantly subjected to external forces. Gore-tex is still considered to be the best, closely followed by eVent and others.
