These are our mid-weight colorful alpaca striped socks and the 1" elastic band is knit at the top of the sock.  These socks were designed by Mary Ann Weerts, the founder.  We needed a smaller micron yarn to create this more intricate design.  This is a great trouser or legging sock for work as this is a mid-weight sock.  These are still soft, warm, and very comfortable yet light weight, and not as thick in your shoe or boot.
