Does anyone have recommendations for boots for heavy snow and ice? I have an unplanned trip coming up to Quebec City for a month, and am scrambling to prepare. High today was -13C (!). I'm hoping an M-65 with a liner and a few layers + scarf will do the trick there (yeah, I know a shearling would be ideal, but expensive for a single trip). I've never done an icy winter before, so welcome any boot recommendations.
