There's a reason why most manufacturers don't make GTX socks - they don't work. They don't breathe much, so your feet get wet from sweat on the inside. And they wet through, so your feet get wet from the outside. A VB sock is better, if you wear a liner or insulating sock inside it to absorb moisture, and change socks as needed.
SealSkinz are better. There are advertised as WP/B, but forget the breathable part. They advertise that the socks are pressure tested to make sure they are WP, so how can they be breathable? They make good VB socks, but they are not particularly fitted well, and they are on the heavy side.
As someone mentioned, the GTX socks would be ok to wear in camp, but a pair of plastic bread bags work better. Put on the bread bags, then your damp socks, then your damp boots. Your feet will feel much warmer.
