I picked up a pair of these Timbs the other day. The price was too good to pass up:

 

Are this Timbs warm? Cause pretty much every timbs I've seen would be total shit during really cold days. You really need GOOD warm boot to be able to be comfy at -40. I have a pair if timbs and they aren't warm enough. Plus they're a bitch to put on

 

depends what kind you get.
