We have owned a pair of these boots for, probably, well over 20 years, as has the rest of my family. If you want warmth in real cold--these are just the BEST!!! Great for ice fishing, snow camping, snowmobiling, hunting, outdoor events which don't require great exertion (ie: lots of standing around, such as, at youth events), extreme cold, emergencies, etc. I have chronically cold feet, but not in these! Tried a new pair on recently, except for being made in China now, seem pretty much the same as mine. Fit was a tad smaller, so might need a bigger size than in the past (We noticed this sizing issue with all Sorels made in China. We wish they were still made in Canada.). The only downside, which is to be expected, is that they are on the heavy-side. But, since they would be too warm to wear every day, even in the north country, that's not much of a problem to us. We love these boots and would always want to keep a pair around for extreme cold conditions! My whole family agrees!
