Heel flap: The heel has 36 sts, beginning with WS row and ending with RS row.
Rearrange sts to center patt over instep. Unknit last purl st of rnd and then move this st from needle 3 to needle 1. Move 1 st from needle 1 to needle 2, and 1 st from needle 2 to needle 3.
There should be 18 sts on needle 1, 18 sts on needle 2, and 36 sts on needle 3. Needle 3 has the heel sts.

The heel is worked with a 3 st garter border:
Row 1 (WS): K3, P to end
Row 2: P3, *K1, sl 1, rep from * to last 3 sts, K3
Repeat rows 1 and 2 until you have 36 total rows in heel flap.
(Heel should measure 2 1/4"

---------------------

Heel Turn
Row 1 (WS): sl1, P18, P2tog, P1, turn
Row 2: sl1, K3, ssk, K1, turn
Note that there will be a small gap between working sts that form heel turn and unworked heel sts.
Row 3: sl1, P to within 1 st of gap, P2tog, P1, turn
Row 4: sl1, K to within 1 st of gap, ssk, K1, turn
Rep rows 3 and 4, until all side sts are worked, end with completed row 4. There should be 20 sts left on heel flap.

Note that for ease of instructions, beg of rnd is now at center of bottom of foot. The needles are renumbered at this point. Needle 1 is beg of rnd.

--------------

Gusset

Divide heel sts evenly onto needles 1 and 3. There should be 10 sts on needles 1 and 3, and 36 instep sts on needle 2.

Pick up 18 sts from side of heel flap, pick up 2 sts at top of gusset (see p. 25).

needle 2: work across instep in pattern st.
needle 3: pick up 2 sts at top of gusset, pick up 18 sts from side of heel flap.
Knit remaining heel sts.

Needle 1 should have 30 sts, needle 2 should have 36 sts, needle 3 should have 30 sts.

Gusset Decrease

Work round 1 once to combine sts picked up and to eliminate gap at top of gusset.
Rnd 1: needle 1: K to last 2 st. ssk.
needle 2: Work patt.
needle 3: K2tog, K to end
Rnd 2: needle 1: K to last 3 sts, K2tog, K1
needle 2: Work patt
needle 3: K1, ssk, K to end
Rnd 3: needle 1: K
needle 2: Work patt
needle 3: K
Repeat rounds 2, 3 until 72 total sts remain.

-----------------

Foot

Continue stockinette stitch on needles 1 and 3, and pattern stitch on needle 2, to desired heel-to-toe length. (approx 8 in)

Toe Shaping

Adjust beginning of round to side of foot as follows:
Knit sts on needle 1 (36 sts). Needle 2 has half of sole sts (18 sts), Needle 3 has half of sole sts (18 sts).

Work decreases as follows:
Rnd 1: needle 1: K1, ssk, K to last 3 sts, K2tog, K1
needle 2: K1, ssk, K to end
needle 3: K to last 3 sts, K2tog, K1
Rnd 2: K around
Repeat rnds 1 and 2 until 36 total sts remain.
Repeat rnd 1 only until 20 total sts remain.
Place sts from top of sock onto 1 needle and sts from bottom onto 2nd needle. Graft toe sts tog with kitchener (see p. 24).
