goretex socks as vapor barrier?

Gore-Tex by design isn’t a vapor barrier.

You could use plastic bags

the socks were too bulky to try. Man my toes were cold, everything else super warm. Should probably just get boots with liners but they would rarely get used.

Bread bags

I use US Divers brand 3 mm closed cell neoprene divers sox for a VBL. These are worn over a thin polyester liner sock. I take one pair of liner socks for each day of winter camping.

I prefer US Divers brand B/C they have factory sealed seams and Right and Left foot shapes for no bunching up at the toes. There is NO other VBL sock that works as well plus it insulates. With the 3 mm thickness plus a thin liner sock you can use your standard hiking boots just as you would with mid weight hiking socks.

I wouldn’t expect gore-tex to be an effective vapor barrier.  As noted the cheapest is bread bags.  Small roasting bags also work well and are more durable.  I typically recommend the thinnest liner you can find, the barrier, and the insulation.  I have a few notes and pointers to other people’s observations about https://verber.com/vapor-barrier/

Large oven bags not turkey bags work great and are more durable in footwear for walking than bread bags. Cheap too.
