[How do you attach it to the base, is it a climber?QUOTE=mosh22;1071791987]I too run a liner with a 95% merino wool sock with 800 gr boots. Works pretty good down to 25-30 degrees, with little wind, but what really helped was when I put a carpet tile on my stand base. That extended my sit time by 100% almost before the chill started to set in on real cold days. I hope to get some better severe cold weather, MUCK boots soon. My brother said they are the shiznet. He works road crew outside all day and never gets his feet cold even standing on snow and concrete.[/QUOTE]
