I had the comparison between a low sock and this quality product while hiking. While the TK has 2 very well adapted to the foot and was very comfortable to wear, I was at the cheapest price after a few hours irritated skin points on the foot, because they do not sit so perfectly on foot. In addition, the feet during long hikes in summer, although warm, but the humidity control does a good job (High quality hiking boots required) and the foot stays dry and waterlogged not.
Conclusion: Should not be missing in your luggage while hiking.
