Cold ground? They're waders, presumably your whole foot is in ice cold water - the ground isn't even half of it. Boot foot waders have insulation all around, including the sole. Isn't the stocking thin? You mentioned neoprene, which is pretty thick, and besides doesn't add a lot of insulation (nowhere near a 1000 gram Thinsulate). Are the stockings a standard thickness - are the boots sized larger to accommodate the stocking thickness, or ???
I picture it as "cold water gets in between the boot and stocking (there's no kind of seal, right?). Water doesn't insulate, so my feet get cold." Are the boots waterproof from both outside and inside, so the boots have insulation trapped in a waterproof compartment? Insulation doesn't do much good if it's soaked with water. If I want the same insulation/warmth as 1000g Thinsulate bootfoots, what socks do I need to wear?
I can understand stocking foot waders for fly fishing on a summer's day where you might otherwise wear the thin, rubberized canvas waders (to keep you dry more than to keep you warm) - I'm having a hard time picturing how they work in an ice cold stream in winter, where you have neoprene and fleece (or long johns) on your legs and a bunch of Thinsulate on your feet with bootfoots.
Sorry for lots of questions, I just don't understand how they work.
