While blisters seem like they would be a fairly minor problem they can make a trip miserable if not treated properly.  When hauling 60 plus pound packs for days on end a blister or two is almost inevitable even in the most comfortable boots.  When this happens proper care is imperative to minimize the amount of discomfort to be endured.  

    The most important thing is to avoid blisters if you can.  When hiking for hours with a heavy pack the body tends to sweat.  The perspiration from your feet can eventually overcome the wicking ability of your socks or the breathing ability of your boots.  When your feet get wet then they tend to slip around more in your boots causing blisters.  The first layer of defense is antiperspirant.  A little sprayed or rolled on the feet will delay the flooding of the system.

    Proper sock systems are as important as the boots you wear.  Winter or summer I wear a double sock system that varies little from season to season.  For a base layer I wear Patagonia Capiline (TM) silk weight sock liners.  In the winter I wear Patagonia Mid-weight Capiline socks and in the summer months I wear the light weight version as the top layer.  I have tried almost every sock on the market and while there are others that may be as good as Patagonia's none are better.

    Proper selection of boots is very important.  Choose boots that are sturdy enough to support the load you carry while still being as light and breathable as possible.  Avoid boots with plastic inserts in the rear.  Make sure and fit your boots well, remembering that your feet swell after a few hours of walking.  Don't be cheap when it comes to foot wear as you tend to get what you pay for.

    For treatment of the inevitable blister you need several items.  First is a single edged razor blade.  This is used to drain the blister and carefully cut away any loose skin.  The next thing is to clean the affected area thoroughly.  I use an alcohol wipe for this.  It burns but it gets the job done.  I then put a small amount of Neosporin Maximum Strength with Pain Relief on the area and cover it with a piece of mole skin cut to the appropriate size.  I then pad the area of the blister with a layer of mole foam, put the socks back on and get back to hauling the pig.  Take every reasonable opportunity to remove the bandage and let the blistered area breath.
