Preemie socks on five dpns.
For a quicker knit-up use four dpns on the leg portion; switch to five dpns at the gusset rounds through the foot and toes.

You’ll notice that at the heel flap you begin with slip one and purl across… That is because you divide for the heel flap by knitting the first twelve stitches of the round onto CONTRAST waste yarn - 4 rows should be fine… and then with your main yarn technically at the end of the round just completed, you purl back across the row (i.e. the last 12 stitches worked). No holes!!!
