32 sts/48 rows = 4 inches in stockinette stitch in the round

Stitch pattern is scaled for each size. Refer to Chart 1[2, 3, 4] for size Small[Medium, Large, Extra large]. Pattern is worked alike for both socks.

Begin lace pattern, using chart 1[2, 3, 4] as appropriate. Work 3 full repeats of pattern.

Heel Flap
The heel is worked back and forth on half the stitches.  The other stitches – the instep sts – will be held until the heel is complete.

Row 16, [WS]: Sl 1, p21, p2tog, p1, turn work.  24 sts rem.

Reestablish round
Knit the heel stitches. With the same needle, pick up and knit 14[16, 18, 20] slipped stitches along the heel flap edge, using the slipped stitches as a guide. Work across the instep stitches - those that were on hold while you worked the heel - in pattern according to chart as established.

With another needle, pick up and knit 14[16, 18, 20] slipped sts along the other side of the heel flap edge, using the slipped stitches as a guide. With this same needle knit 9[10, 11, 12] sts from the heel sts. The start of the round is at the center of the heel. There are now 46 [52, 58, 64] sts for the sole and 28[32, 26, 40] sts for the instep.

Gusset and foot
For the gusset and foot, the sole stitches are always knit, and the instep stitches are worked in pattern according to chart as established.  Place markers if you find it helpful.

Gusset decrease round: Knit until 3 stitches before the instep, k2tog, k1. Work in pattern across instep sts; k1, SSK, k to end.
Work 2 rounds even.
Repeat the above three rounds until 56[64, 72, 80] stitches remain

Continue in pattern as established until the foot from back of heel measures approximately 1.5[1.5, 2, 2] inches less than desired finished length. It is possible to start toe shaping at any point of pattern repeat, but I recommend working a full pattern repeat if at all possible for the foot size desired.

Toe
The toe is worked in stockinette stitch.
Decrease round: K until 3 stitches before the instep, k2tog, k2, SSK; knit until 3 sts remain on the instep, k2tog, k2, SSK, k to the end of the round.
Repeat the above two rounds until 8[9, 10, 11] stitches remain on each needle.

Continue, working every round as a decrease round until 2 stitches remain on each needle. Break yarn. Thread yarn through the remaining 8 stitches and pull tight to close.

Weave in ends. The socks can be worn without blocking, but the stitch pattern will benefit from being blocked lightly.
