I typically wear an oversized trail runner with a thin liner sock and/or a thicker merino sock (depending upon conditions). I then wear a goretex sock over the other sock(s). I'll also wear knee-high waterproof gaiters. This works fine for keeping my feet dry and warm enough for my encountered snow conditions. Obviously if I step in a creek over the top of my WP socks, my feet will get wet but I fail to see how it would be any different with a goretex boot.
We usually follow "trails" in terms of our selected route but seeing as how the trail is under 4-10 feet of snow with no tracks, it's really the same as just going off-trail in terms of the conditions. Under a bunch of snow, the "trail" looks just like the rest of the surroundings. Most of our snowshoeing is either in the Sierra or up around Tahoe.
Like I said above, trail runners work okay for me most of the time. It's just side hilling that's awkward.
For non-technical terrain, I find both my microspikes and Kahtoola KTS crampons work fine with my trail runners too.
