Not everyone needs warm footwear in their home state. If this applies to you, rather than purchasing boots of that type, an inexpensive shortcut is this: buy WOOL or wool blend socks. Thin is good. Wool is warmer and dries from the inside out. Use thin cotton or nylon socks as a first pair, if you get itchy. Make boot liners from ziplock or plastic grocery bags. Tinker with how much plastic to wear ahead of time. You want your whole foot covered, but no tacky excess adorning your ankles. Make 2 or 3 pair of these as the plastic can tear. Put on your socks, slip the liner over, then into your boots. Even if your boots get soaked, your feet will be dry and therefore, warm. You can even wear soaked boots the next day (stuff with newspaper overnight). It is the wet foot that you want to avoid. Enjoy your trip!
