I'm om my 4th year with a pair of Action Targets with the 400g of Thinsulate. They are warmish, comfortable for long walking and so far have been durable in everything from stubble fields to moose bush.
For many years before I got the Actons I wore a pair of the Nokian Finnjagd style as well as the Kamik type with the felt liners. The Nokians were beautys, they fit tight and were great for walking but being without any type of insulation were not at all warm when I stopped moving. I've done and still do a lot of moose hunting wearing the Kamik felt lined type of boot because they are very warm and dry but they wear out fast (but only cost $35) and are crappy to walk in when out for the chase.
A sort of rubber boot, my old Sorel Bisons (inexpensive) RBLT's have been keeping my deer hunting feet warm and dry, walking and standing, for over 30 years. A couple of years ago I bought a new pair of Sorel Caribou (spendy) to replace the Bisons. The Caribou are very good boots, much bettter quality than the Bisons, but they haven't made it out to the field yet.
