As Coastie said i think, no one boot can do it all. My feet have never gotten cold in a pair of pacs/ sorrels, even if wet those wool felt liners seem to did the trick( dont think there measured like thinsalate is for effectiveness& selling weight) A lill harder to walk in at times , i always take 2 pairs/diffent boots with me to camp.

There was that famous young guy( rulan? garner gold metal wresting winer, snowmobiling in yellowstone a few yrs back& got stuck overnite in a snow storm( had a cell phone etc & was in contact with ppl - but didnt matter)
If im not misttaken he had on a hunting type boot med weight types too.

Got out ok but with serere frostbite to his feet,toes etc, dont know if there still right today his feet.
Heard sorrel was going under / and Cloumbia sportswhere would own them& make the boots overseas.
