The Khorasan Socks are a cable work sock knitted in the round from cuff to toe.
The unusual eyelet ribbed cuff leads into a simple cable, which looks much more complicated than it actually is.
Video tutorials are linked into the pattern to help you with the cable work. You can see them here and here for the stitch shuffle involved.

Six sizes are included so you can have a pair for every member of your family, and all sizes are colour coordinated.

I do not recommend working these socks two at a time as there is a stitch shuffle in the pattern.
