If you’ve been searching for a Free Lace Sock Pattern that feels elegant without being overly complicated, this one is for you—plus it’s one of my favorite free sock knitting patterns for knitters who want something pretty and wearable.
The Martha Socks feature an all-over lace pattern that adds beautiful texture from cuff to toe while still keeping the knitting rhythmic and enjoyable. Built with classic top down heel flap construction, this pattern gives you the polished look of lace socks with the dependable fit of a traditional sock shape. If you love feminine sock knits that still work for everyday wear, this free lace sock pattern checks every box.
The all-over lace keeps these socks visually interesting from start to finish, which means no boring stockinette stretches to power through. They’re designed specifically with ladies in mind and have a refined, delicate look that pairs beautifully with both dress shoes and lounging at home. If you’ve wanted lace socks that are pretty but still practical, Martha Socks may become your new favorite cast on.
If you enjoy knitting socks that look impressive but use familiar construction, this free lace sock pattern is a great project to keep on your needles. The repeating lace motif is easy to memorize after a few rounds, making these the kind of socks you’ll want to knit more than once.
The tweedy yarn gives the lace extra depth and texture, helping every eyelet stand out beautifully. Between the classic heel flap and the feminine lace design, this pattern balances beauty and function in the best way.
What Materials Do You Need for This Free Lace Sock Pattern?
For this free lace sock pattern, I usedKnitPicks Stroll Tweed paired with 2.25mm double pointed needles . Stroll Tweed is one of my favorite sock yarns for textured patterns because the subtle flecks add dimension without overpowering the lace details.
The yarn has enough stitch definition to let the lace shine while still being soft enough for comfortable everyday wear. Combined with 2.25mm DPNs, it creates a durable fabric with great stretch and structure for socks that hold their shape beautifully.
If you prefer working with a wool/nylon sock blend that wears well over time, this pairing is hard to beat. It gives the socks enough sturdiness for regular wear while still keeping them soft and lightweight.
I always recommend sticking with a yarn that has excellent stitch definition for lace socks so the pattern doesn’t get lost. With Martha Socks, that crisp definition really makes the lace motif pop.
How Is This Free Lace Sock Pattern Constructed?
This free lace sock pattern is worked from the top down using traditional heel flap construction, which makes it a great option for knitters who already love classic sock knitting methods. The lace pattern flows throughout the sock for a polished, cohesive design that looks intentional from every angle.
Because the lace repeats all the way through the sock, these stay engaging on your needles from cuff to toe. Once the pattern repeat clicks, it becomes an easy rhythm that makes this project both relaxing and rewarding.
If you’re newer to lace socks, don’t let the pretty texture intimidate you. The repeat is manageable and pairs nicely with the familiar structure of a heel flap sock.
This is the kind of project that looks advanced when finished but is very approachable if you’ve knit socks before.

Each of these patterns offers a different take on textured or lace sock knitting, so there’s something for every mood and skill level. Whether you want more delicate lace, simpler texture, or a quicker ankle sock project, these are all great next picks.
Lace socks are one of my favorite ways to make everyday knitting feel a little more special, and Martha Socks are such a satisfying project when you want something beautiful on your needles.

Separate stitches on your dpn as follows:
1st needle – 20sts
2nd needle – 15sts
3rd needle – 35sts
Work in 1×1 rib (k1p1 around) for 12 rounds
Knit around 1 round.
Then work in pattern as follows:
Round 1 – (p2, k1b, p2, k2tog, yo, k1, yo, ssk) repeat (to) around
Round 2 – knit around
Round 3 – (p2, k1b, p2, k5) repeat (to) around
Round 4 – Knit around
Repeat Rounds 1–4 until the leg measures approximately 6 in/15 cm from the cast-on edge, or to desired length.
Heel Flap
Next round: Work across the 1st and 2nd needles in pattern. Place these stitches on hold. The heel flap will be worked flat, turning after each row, with only the 35 sts on the 3rd needle
Row 1 (RS): (sl1, k1) to last st, k1, turn work.
Row 2 (WS): sl1, purl to end, turn work.
Work rows 1-2 total of 16 times.
This is a total of 32 rows.

Row 2 (WS): sl1, p6, p2tog, p1, turn work.
Row 3: sl1, knit to 1 st before the gap, ssk, k1, turn work.

21 sts remain.
Knit across these heel stitches slipping the first st.
Gusset
With needle 3, pick up and knit 17 sts along the edge of heel flap, PM,
Knit across 35 on needles 1 and 2 (combining them all to needle 1) PM,
Pick up and knit 17 sts along heel flap onto needle 2,
K11 sts onto needle 2, mark the new BOR (located at the bottom of the foot).
[90 sts]
Round 1: knit around
Round 2: knit to 3 sts before marker, k2tog, k1, sm, work in pattern to next marker, sm, k1, ssk, knit to end [2 sts dec]
Work rounds 1-2 a total of 10 times. [70 sts]
After last round, remove bor marker, knit the stitches on needle 3, place bor marker.
Foot
Needle 1 should now have 35 sts
Needle 2 should have 18 sts
Needle 3 should have 17 sts
The new beginning of round is now needle 1.
Continue working in the round in established pattern (the bottom of foot in stockinette and the top in lace pattern) until the piece measures 8ins (or desired length) from back of heel, or 2in short of desired foot length. (Example: I wear a US size 10 and need to knit to 8.5ins before the toe decreases.)
The lace pattern ends here. You will work in stockinette throughout the remainder of the socks.
Toe
Round 1: k1, ssk, knit to 3 sts before marker, k2tog, k2, ssk, knit to 3 sts before end of round, k2tog, k1 [4 sts dec]
Round 2: knit
Repeat Rounds 1–2 until Round 1 has been worked a total of 11 times and 26 sts remain, ending after a Round 1.

Cut yarn leaving a 12 in/30 cm tail, then graft toe using Kitchener stitch.
Weave in all ends
Kitchener stitch:
Place half the stitches on one needle, half the stitches on the other needle, (top and bottom NOT side to side)
Cut yarn (leaving a long yarn tail) and thread through a blunt needle.
Set-up steps: Insert needle purlwise (back to front) through the first st on front needle, leaving the st on the needle. Then insert needle knitwise (front to back) through the first st on the back needle, leaving the st on the needle.
Step 1: Insert needle knitwise through first st on front needle, then slip this st off the needle.
Step 2: Insert needle purlwise through the second st on front needle, leaving the st on the needle.
Step 3: Insert needle purlwise through first st on back needle, then drop this stitch off the needle.
Step 4: Insert needle knitwise through second st on back needle, leaving the st on the needle.
From this point to the end, repeat steps 1-4.
Kitchener stitch can be intimidating, but you get into a rhythm:
Front needle: knitwise drop off, purlwise leave on,
Back needle: purlwise drop off, knitwise leave on,
Repeat!
At the end of the row, there is only 1 stitch left on each needle.
Work steps 1 and 3 once more.
