Oh boy, where to begin. I guess I’ll just end. This is basic heat transfer and thermodynamics. Rubber boots are a material between a heat source (your body) and something at a lower temperature, the environment around you. Like metal, they have their own thermal conductivity. This is the ability of a material to conduct heat from one side to another. I didn’t say anything about conducting cold, so I have no idea where that came from. And I didn’t put up any charts, those were pictures to illustrate the different methods of heat transfer, both of which included someone sitting, showing the heat loss due to conduction. I’m out.
