Crochet Snug Mosaic Socks Pattern

Crochet mosaic socks size:

Size: US 7 – 7.5 – 8 (24 – 25 cm). The size can be easily adjusted by crocheting the sole section slightly longer or shorter, and by increasing the hook size by 0.5–1 mm.

Length to the heel:
The heel usually measures 25–30% of the total sock length, which is approximately 7–7.5 cm for a US size 7–8.

To calculate the length of the foot before starting the heel:
Total length – heel length = length to heel
25 – 7 (7.5) = 18 (17.5) cm (7 in)

Work the sock until this length before beginning the heel.

Sock width: 10 cm (4”).

This sock is not stretchy. If you plan to use a different yarn weight or want to make the sock wider, the total number of stitches for the mosaic section must be a multiple of 6.

Gauge: 15-16 sts and 15 rows = 10 by 10 cm (4” by 4”)

Common abbreviations of crochet stitches (US):

ch – chain

SC – single double crochet

SC blo – single crochet back loop only

DC – double crochet

DC3tog – Double crochet three together

Drop-Down DC – Drop-down double crochet:  Insert the hook into the front loop of the stitch below the previous row and complete a double crochet as usual.

sl st – slip stitch

Yo – yarn over

st(s) – stitch(es)

FPDC – front post double crochet

FPSC – front post single crochet

BPDC – back post double crochet

FSC –  Foundation Single Crochet:

Step 1: Ch 2.

Step 2 : Insert the hook into the 2nd chain from the hook. Yo and pull up a loop. Yo and pull through 1 loop on the hook — this creates the first chain of the FSC. Yo and pull through both loops on the hook — this completes the first foundation single crochet stitch.

Step 3: For the second stitch and all following stitches: Yo, insert the hook into the chain created by the previous stitch (created in Step 2). Yo and pull up a loop. Yo and pull through 1 loop (forms the next chain). Yarn over and pull through 2 loops (completes the foundation single crochet).
Repeat Step 3 for each stitch until you reach the desired number of stitches.

Repeat Rounds 1–12 until the sock reaches the calculated length of 18 cm (7 in) (based on the length-to-heel calculation described earlier).

Note: To reach the desired length, I repeated only 10 rounds instead of the full 12 rounds.

Crochet the heel opening section:

Round 1: Color B: Work 15 FSC for the heel opening, skip the next 15 stitches, then continue working the mosaic pattern starting with Round 11 (or the next round needed based on the last round you worked): 1 drop-down DC into the flo of the next stitch 2 rows below, SC blo in next 2 sts, [SC blo in the first st,  1 drop-down DC into the flo of the next stitch 2 rows below, SC blo in next st,  1 drop-down DC into the flo of the next stitch 2 rows below, SC blo in next 2 sts] – repeat twice. Join in the back loop of the first SC introducing Color A. (30)

Round 2: Color A: SC blo in next 15 sts, then continue working the mosaic pattern of  Round 12: SC blo in next st, 1 drop-down DC into the flo of the next stitch 2 rows below, SC blo in next st, [1 drop-down DC into the flo of the stitch 2 rows below, SC blo in next 3 sts, 1 drop-down DC into the flo of the next stitch 2 rows below, SC blo in next st] – repeat twice. Join in the back loop of the first SC introducing Color B. (30)

Repeat Round 1-11 of the mosaic pattern.

Crochet the cuff: 

Color A: 

Round 1: Ch 2 (count as DC), DC in each st around. Join with sl st to the top of starting ch-2. (30)

Round 2: FPSC+ ch1 (count as FPDC), BPDC around the next DC, [FPDC, BPDC] – repeat around. At the end of the round, join with a slip stitch under the Ch 1 of the first FPDC.

Rounds 3-5: FPSC+ ch1, BPDC, [FPDC, BPDC] – repeat around. Join.

Crochet the heel:

Color A:

Attach the yarn to the central stitch (8th) of the 15 skipped stitches that form the heel opening.

Round 1: Ch 2, DC in next 6 sts, DC3tog, DC in next 13 sts, DC3tog, DC in next 6 sts. Join to the top of starting ch-2.

Round 2: Ch 2, DC in next 5 sts, DC3tog, DC in next 11 sts, DC3tog, DC in next 5 sts. Join to the top of starting ch-2.

Round 3: Ch 2, DC in next 4 sts, DC3tog, DC in next 9 sts, DC3tog, DC in next 4 sts. Join to the top of starting ch-2.

Break the yarn and pull the tail through the front loops of the remaining stitches. Pull snug to close the heel.

Weave in all yarn ends. Repeat the pattern for the 2nd sock.
