It depends on the water. If its easy wading and hot out, i might go barefoot with just shorts and a shirt. I have a pair of waders but i have never used them. i dont own wading boots, but I should probably invest in a pair. Where I live most of the fishing is done from shore or from a boat. I like fishing barefoot though, it makes me feel close to nature. I like having the bare essentials and still catch fish, although the looks I get from the guys all decked out.
