Very Versatile
Great thin socks with multiple uses.
I like to fold them over right where the knit pattern changes on the calf, which is about the exact length for my boots so I can double the layers and not have excess material at the top. Obviously you can fold them over differently to work on any length boot.
They also make great liners to use under wool socks. Very thin, and hold close to the skin but loose enough not to restrict blood flow.
And they take up very little space so they're perfect as backup socks that you can stuff in a pocket. They weigh about 80g and roll into the size of a baseball. (Size 42)
