I bought some Hodgman breathables and some Hodgman boots to go with them. Under them I wore a pair of sweatpants and some polypro longjohns. For my feet I used some polypro socks and thermal socks. My legs were ok but after several hours in the river my feet were freezing. What are you guys wearing under your waders to keep warm. I have looked at the fleece pants and the fleece lined neoprene socks. Are these good investments or does everyones feet get cold standing still for long periods of time?
