I wrote up the recipe for those interested:
Use any toe-up pattern and include my instructions.
CO 30 sts on two needles, with Judy’s magic cast-on (I knit two at a time, with magic loop, on circulars).
Increase on both ends of both needles, until you have 62 sts, on the two needles.
When you have the final number of sts, start the lace panel on the instep: K2, knit the sts of the lace-panel, knit all sts remained. On the other sock when you knit the instep knit until the last 15 sts, work the lace-panel, knit 2.
Make the heel whenever you have to, it does not affect the lace-pattern.
You can add increases on the back side if needed.
When you have the desired length of patterning, start knitting the K1/P1 ribbing. BO using an elastic BO.
And you are done.
