If you are hiking a lot in conditions with snow on the ground, you will need an insulated hiking boot with good traction. Pair them with gaiters, and you should have dry, warm feet. If you're in wet winter conditions (mostly mud), you can use a full length set of gaiters (up to your knees) over your regular waterproof hiking boots. Read about gaiters here. You can use traction devices on your hiking boots to increase the amount of traction you get on icy trails. Read about hiking boot traction devices here. If your winter hiking conditions are dry and cool, no need for special boots. Be sure your socks are thick enough to handle the cool temperatures without being too bulky inside your boots. You want good circulation to your toes.
