I wore my Sorel waterproof winter boots all year long when working outside and I only ever had wet feet from sweat. I bought them back in 2001 and I wore them until the stitching came apart this past winter. So they are durable.
^Closest in appearance to the boots I have.
I had a set of loose fitting Columbia rain pants and jacket which I could put on or remove without removing my boots and they did a decent job, but they don't breath well so I had them off as soon as the rain let up.
