I wanted to ask, I've never owned pack boots before. From looking at some reviews and pictures, they appear to be kind of bulky. Are they okay for hiking over some mild terrain for a couple miles? I really don't like bulky boots or clothes, but that can be hard to avoid when it's really cold. I'm leaning towards a pac boot like Hoffman's with 400g insulation liners and 200g insulation in the boots. They're lighter and smaller than the felt liner boots from Schnee or Hoffman. I like the idea of the felt holding heat better when sitting, but I don't want something that's clunky and bulky. Thanks
