I wear the NRS Boundary socks. They’re like waders for your lower legs! Wool socks go underneath and my wading boots go over the neoprene socks.
As for pants, I wanted something breatheable but tough, to protect my legs from poison ivy and thorny plants. I’ve been real happy with a pair of Blackhawk Tactical Pants.
Sorry I don’t have links. As a newbie I was informed I need at least three posts before I can include live links…
