I work in construction and I wear boots 12+ hours a day. Often in hot weather, be it the Gulf Coast or southern Arizona. My life changed when I switched to buying high quality wool socks. Yes, they're $20 a pair or whatever. You don't need that many, and the difference long-term is unbelievable. Also, darn tough has a lifetime warranty on their socks. Read that again slowly. Lifetime warranty. On socks.
