The pictured sock for this pattern is by BabyToes - she added cables to it, and worked in worsted weight yarn on size 8 needles.

The pattern itself is written for 4ply fingering weight yarn, knit at a tight gauge - about 8 sts per inch, though the author does not specify. There is a nice chart of stitch counts for differing sizes, but no information on how to adjust for different gauge yarns.
