I use these socks for travelling and light hiking. For travelling, they are tremendous. They take up little space and are extremely light in weight. You can hand wash them in minutes, and they line dry in minutes. For light hiking, they are very good. There is a little extra padding in impact areas. For long hikes or hikes with a backpack, I would at least go with midweight socks, or you could double up on the lightweight socks. I love the material they are made of. I wore them at 0 degree weather and 110 degree weather and the socks were always comfortable. My feet were never cold or hot. They wick moisture well. If you want to avoid wool and travel and/or hike lightly, these socks are for you.
