Try Derri Boots.

I had a pair 25+ years back, so don't know what they're like now.
They were waterproof, but your feet would soon be saturated from
sweat, like wearing a plastic bag. Tolerable for short use, useless
for all day wear.

And after wearing them all day, the green fumes that rose from them
ensured the room was evacuated rapidly.
