I have been hunting Whitetails here in Ontario Canada for the better part of 40yrs and it is a challenge keeping the feet warm and still have a boot comfortable enough to walk in. I have used the toe warmers , hand warmers etc and they do the trick, however, last year my SIL bought me Muck Mens Artic Pro boots

For the first time ever, I had warm (and dry) feet throughout our Nov rifle season with no toe warmers. I did have 1 morning they started to get a bit cold and realized it was because I didnt dry them out properly the night before so my feet got a bit damp before I got to stand.
Of course, that was also the day we just happened to have a snowstorm blow through and last a few days
Once snow flies and I start bow hunting, I use Cdn Forces Mukluks with reversible liners

They are ok for walking to the stand and back, however, they don't have much side support so good for walking slow, however, I don't recommend running in them.
Nicest thing about them the liner is a type of Wool and double layered, essentially a liner inside of a liner and sewed at the top, so if your feet perspire, the liners can be pulled, turned inside out and put back in.
thats my .02c for hunting in snow in Ontario
