How about gaiters made of Loden cloth? I tried canvas, coated synthetics etc. I personally don't like the breathable synthetics. Imho they don't breathe that good ... Canvas is great in summer, but wool works in summer too. And the mechanical protection of Loden cloth is much better. The funny thing is: in winter the boot feels dry and warm under the Loden. Even when it rains. The woolen gaiters get heavyer when wet, but it's really ok.
It is an old tradition in the Alps, but people nowadays seem to go for the Gore-Tex option. Kind of strange imo. My next trouser/overall will have 3/4 legs only, to wear the Loden gaiters permanently. Nobody needs trousers on the lower part of the leg, always wet ...
