I farm and I’ll wear Mucks. They eventually wear out and the neoprene gets snagged with barbwire, but they’ll go for about 3 winters of daily use for 6 months IME before it’ll get a hole around where the neoprene meets the rubber. Leave room for a good pair of wool socks and I’ve worn them to -43 as long as I’m moving around. But I’m also not very susceptible to cold, so YMMV.
