These are Tey Art's mid weight geometric striped socks and the 1″ elastic band is knit at the top of the sock. They needed a smaller micron yarn to create this more intricate design.
These are still soft, warm, and very comfortable yet lighter weight and not as thick in your shoe or boot.
This is a great trouser sock for work as this is a mid weight sock.
41% Alpaca, 34% Acrylic, 23% Nylon and 2% Spandex.
