Link: Knitting Sock knitting
Sole gusset
- I knit a 64 stitch sock, so knit the heel flap over 32 stitches. If you have knit socks before it should be easy to adjust the stitch counts below to a larger or smaller size.
I’ll do a slip stitch heel for 32 rows - I count to 16 elongated stitches - then a standard heel turn: slip 1, k17, ssk, k1, turn. Slip 1, p5, p2tog, p1, turn. Continue heel turn until final p2tog.
Then knit across sole stitches, pick up 18 stitches along the side of the heel flap, knit the instep and pick up 18 stitches on the other side of the heel flap, then k9 to the centre of the sole.
I knit on DPNs, so I arrange to have 27 stitches on needle 1, 16 stitches on needles 2 & 3 for the instep, and 27 stitches on needle 4, with the new beginning of round in the centre sole.
K 1 round
Decrease: needle 1 - k11, k2tog, k14, knit instep in pattern, needle 4 k14, ssk, k11.
K 1 round
Decrease: needle 1 k10, k2tog, k14, knit across instep, needle 4 k14, ssk, k10.
Continue alternating knit rounds and decrease rounds until you have 16 stitches on needles 1 and 4.
