It depends on your hunting territory. I hunt elk in mountains over 11000'. It is rocky, snowy, uneven terrain and sometimes I have to carry heavy loads on my back. I love Meindl Perfekt Hunters. They have good ankle support, an excellent sole that grips well on snow, and requires zero break-in time (at least that was my experience). They cost about $280, so they're not cheap. If you don't have as challenging ground to walk over (which demands excellent ankle support and substantial soles), you can probably find something less expensive that will meet your needs.

I wear a heavy outer sock and a thin inner sock made of wicking material. My feet sometimes get cold when I stand still for an extended period of time. This happens when the temperature is below 25 degrees. I think sometimes you just are stuck with cold feet. Get up and move around to get your blood flowing when your feet get too cold. Your toes are extremities. When you pack them into boots and tighten the laces up tight, I imagine that diminishes blood flow and hence warmth to your toes. But maybe others know a secret to keeping your feet and toes warm that I don't know about.
