I'm thankful to have learned such lessons in times of plenty, they are as follows:
A Hiking System
Just like how an infantryman’s kit works with him to create a “weapons system,” a hiker and his gear turn into a “hiking system” while on the trail. Working together, the components form a gestalt that can accomplish more than the sum of its parts.
A good pair of trail shoes or boots is the foundation of the hiking system. Footwear that has been broken-in and conforms to the hiker’s foot before the hike begins will be the most comfortable and cause the fewest problems along the way. Wearing footwear a half-size larger than street shoes allows room for the foot to expand as blood flow increases during exercise.
Wool socks wick away moisture during use, keeping feet dry and happy. I had expected wool socks to be like a wool sweater – scratchy and uncomfortable in the heat. In reality, Merino wool is much softer than cotton, and wears very comfortably.
