I use the GTX boots year round in Colorado. They are excellent in every type of weather and they breathe very well.
I hate to sound as though i'm picking on Gershon again here. I'm not! I just want to point out, once again, that everyone's feet are different! Goretex turns my feet into a sauna. Also, when water got inside (bound to happen sooner or later), the Goretex lined boots took a long time to dry. Been there, done that--in Colorado, in fact--even setting the boots out in the lovely warm sunshine and breeze, it took two days to get the insides dry.
With trail runners, I can splash through a ford (no bothering with changing shoes) and walk shoes and socks dry in an hour. For snow, I have a pair of lightweight insulated boots to wear over them. I must admit I haven't done enough long snow hikes to determine if the overboots make a difference.
Your Mileage May and probably will Vary.
Bluefish, looks like a lovely trip despite the blisters!
