I wore standard socks with my waders yesterday and stayed warm. Of course I was peddling all over the place and getting some exercise (looking for the elusive fish that I heard were in LJ at one time ).
For my hands, I wore some of those gloves that are fabric on the back of the hand side, and some grippy material on the palm side. Kept me warm enough and was able to work the rod/reel. Can't remember where the gloves came from, but some local store, Wally World, Home Depot,,,,
