The Basic Worsted Sock Knitting Pattern is Day 1 of my 2025 Digital Advent Calendar. Through December 31, 2025, it will be available here on the blog. For daily emails letting you know when the next update is posted, please sign up for the dedicated Advent calendar section of my newsletter.
This sock knitting pattern is designed to help newer sock knitters become more comfortable with basic sock construction before tackling socks knit with fine yarn on small needles. A worsted-weight sock will make it easier to see each component of the sock, and fixing mistakes is easier with larger stitches.

Abbreviations

- RS = right side
- sl = slip stitch with yarn held in back
- ssk = slip two stitches individually knitwise and knit together through the back loop
- WS = wrong side
Pattern Instructions
Using your preferred cast-on method, cast on 44 (52, 60, 68, 76) stitches. Join for knitting in the round and take care not to twist. Place a marker at the join to mark the end of the round.
Work 10 rounds of k2, p2 ribbing.
Knit in stockinette stitch until the leg of your sock measures 6” (15 cm) from the cast-on edge. You can adjust the length of the leg by knitting more or fewer
rounds, but know that this will affect your yarn requirements.
Heel:
This sock uses a heel flap and gusset for a snug, highly customizable fit. You’ll work your heel flap using the last 22 (26, 30, 34, 38) stitches of your sock. Work in pattern across the first 22 (26, 30, 34, 38) stitches.
Now begin working your heel flap as follows:
Row 1 (RS): *Slip 1 purlwise with yarn in back, k1, repeat from * to end of row.
Row 2 (WS): Slip 1 purlwise, purl to end of row.
Work these two rows until you have 22 (26, 30, 34, 38) rows total, ending after working a WS row.
Now it’s time to turn the heel. For each slip stitch in the following instructions, slip your stitch purlwise with yarn held in back (RS rows) or front (WS rows).
Follow these steps:
- K13 (15, 17, 19, 21), ssk, k1, turn.
- Sl 1, p5, p2tog, p1, turn.
- Sl 1, knit to within first stitch from gap, ssk, k1, turn.
- Sl 1, purl to within first stitch from gap, p2tog, p1, turn.
- Repeat steps 3 and 4 until you have used up all the stitches in your heel flap, ending on a WS row.
Gusset: K7 (8, 9, 10, 11) across heel flap and place marker. Rounds will now start in the middle of the heel flap. K7 (8, 9, 10, 11) to complete heel flap. Pick up and knit one stitch in each of the slipped edge stitches along the heel flap. (11 [13, 15, 17, 19] stitches picked up along edge of heel flap). Pick up and knit one additional stitch where heel flap and instep join. Knit across the instep stitches. Pick up and knit one stitch where instep and heel flap join, and then pick up and knit one stitch in each slipped stitch along the edge of the other side of the heel flap. (11 [13, 15, 17, 19] stitches picked up along edge of heel flap). Work remaining stitches from heel.
Work one round, knitting the sole stitches and working the instep stitches in pattern.
Work the gusset decreases as follows:
Round 1: Knit to three stitches before instep, k2tog, k1, work instep stitches in pattern, k1, ssk, knit to end of round.
Round 2: Work one round, knitting the sole stitches and working the instep stitches in pattern.
Repeat Rounds 1 and 2 until there are 44 (52, 60, 68, 76) stitches total on your needles.
Remove end of round marker, knit across remaining sole stitches to beginning of instep, and replace end of round marker. This will now be your beginning and end of round for the rest of the sock.
Foot:
Continue knitting in stockinette stitch until foot measures approximately 2” (5 cm) shorter than your desired length. To determine the length of your sock’s foot, measure from the outside of your heel to the tip of your toes. Compare that to the length of your sock from the deepest part of the heel to the working edge.
Toe:
When you’ve finished knitting the body of your sock, you’ll need to close the toe. Work the following instructions:
- Instep stitches (first 22 [26, 30, 34, 38] stitches of the round): k1, ssk, k16 (20, 24, 28, 32), k2tog, k1. Repeat for sole stitches (second 22 [26, 30, 34, 38] stitches of the round).
- Knit all stitches in the round.
- Repeat steps 1 and 2 until you have 16 (20, 20, 24, 24) stitches total. Note that for each repeat, you will have two fewer stitches between your ssk and your k2tog than you did on the previous repeat.
- Move your stitches onto two needles, 8 (10, 10, 12, 12) per needle, with the sole stitches on one needle and the instep stitches on the other.
- Graft your toe together using stockinette grafting.
Break yarn, weave in ends securely, and block.
