Re: Blister Prevention
I have put in several thousand miles hiking in the Rockies and Appalachian mountains, and spent several years buying timber in western VA and southern WV. My answer is simple but not necessarily cheap.
I wear a set of polypropolene liner socks under a paid of Thorlo either Mountaineering or Hiking Socks. The Thorlo socks are stupid expensive for socks but they can not be beat. The liner socks keep any movement of your feet inside your boots from rubbing on your foot. They also wick moisture away from your feet.
The other thing is to carry along enough socks to change them frequently. Ideally enough to change to anew pair at least once a day. If the trip is to long then at least enough to wash them out and let them dry and still be able to change them every day. If you do get a hot spot stop immediately and put some moleskin on it.
Good Boots, Good Socks, Dry Feet, if that does not prevent blisters nothing will.
