I'll test the Seal Skinz socks this winter and early spring and if they don't work will give the Gortex a try.
I swear by my SealSkinz! Have done snow rides, wet rides, long road rides and bikepacking trips in them and I tell you what, they saved me from chilblains when I though nothing would. Going through creeks and accidentally putting my foot down, I always manage to have dry toes on the other side. Even if the water gets through (if you fully submerge them or it is pouring rain), they are insulted enough that the wet socks stay warm.
Hope you enjoy them!
