In Alaska the ankle fit hip boots, usually LaCrosse, and the long HH Impertech coat were almost a uniform. Now I would go with Gore Tex Hip boots and a more conventional hiking/hunting boot that could take being wet.
Go with mostly wool and synthetics. If you get down items get the Hydro Tech treated ones that repel moisture. A vest and/or a light down sweater are nice if you stop to glass. Treat yourself to some Alpaca socks, I just get crew socks and use them for liners, Dahlgren has a good hiking model. These are 2-3 times warmer than wool and wick and dry faster. You can put a fresh pair over wet feet and they are warm again in minutes. I would double up on rain gear with a light two layer gore tex jacket and then the HH Impertech for heavy rain. The gore tex for wet brush, or if you take a spill, or are in a boat.
