Mud? Ditch the loafers, the slick-sole shoes, the tennies, etc. Wear some light hiking boots with an aggressive tread. I know it's a concept for city-slickers. But really, invest in decent breathable boots that are waterproof. Gortex-lined boots are great. Then invest in some smart hiking boot socks or Dri-Tech Moisture Control Crew Socks. Either will do. Your feet will thank you. And don't forget to break them in before you go! Geesh, for most of my life I've worn boots to work or boots to accomplish outdoors work in around the yard or while hiking or fishing in Alaska. Boots just feel right -- even working in an office environment. With the right pair of boots on, I'm ready for anything.
