About this pattern
This pattern makes a pair of navy blue socks with a ribbed cuff, worked mainly in single crochet (UK double crochet) with worsted-weight wool-blend yarn on a 5.0mm (US H/8) hook. Each sock takes about 200 yards; gauge is 16 stitches and 18 rows to 4 inches. The pattern includes a heel flap and gusset decrease rounds, and a locking stitch marker is recommended.
These navy blue cuff socks are worked almost entirely in single crochet (UK: double crochet), the firm, close stitch that gives the fabric its warmth and durability. The ribbed cuff begins as a flat strip worked back and forth through the back loop only, which creates the stretchy vertical ribs typical of hand-knit-style socks. From there the piece turns a corner and continues as a tube, so the whole sock relies on one stitch family rather than a mix of textures.
Construction starts with a ribbed rectangle rather than a cast-on tube: the Foundation rows build a strip that becomes the cuff, after which stitches are picked up along its edge to begin the foot. A Heel Flap is then worked back and forth across sixteen stitches with slip-stitch selvedges, and a Setup round picks up stitches along both flap edges and across the waiting instep stitches before gusset decrease rounds bring the stitch count back down around the heel turn.
Materials
Yarn
- Worsted weight yarn (weight category 4) , approximately 200 yards per sock (400 yards total for the pair)
- The sample uses a wool blend in navy blue for warmth and durability
- Look for a yarn with some nylon content if you want extra strength in the heel and toe
Hook
- 5.0mm (US H/8) crochet hook for the main sock body
- 4.5mm (US 7) crochet hook for the ribbed cuff (optional, creates a snugger fit)
Notions
- Stitch marker (locking style works best)
- Tapestry needle for weaving in ends
- Scissors
- Gauge
- 16 stitches and 18 rows = 4 inches in single crochet worked in continuous rounds.

Finished dimensions
Foot length: 9 inches (adjustable)
Cuff height: 3.5 inches Foot circumference: 8 inches (unstretched)
The ribbed cuff stretches significantly, so these will fit a range of ankle sizes comfortably.
Hook
5.0mm (US H/8) crochet hook for the main sock body 4.5mm (US 7) crochet hook for the ribbed cuff (optional, creates a snugger fit)
Notions

Transition round
Place your stitch marker in the first stitch. From here, you’ll work in continuous rounds.

Thank you so much for choosing this pattern for your next cozy project. I truly hope you love making these socks as much as I loved designing them. If you give them a try, I would absolutely love to see your finished pair. Tag me on Instagram or share a photo in my Facebook group. Nothing makes my day like seeing your beautiful creations.
If this pattern is calling your name, go ahead and save it to your Pinterest boards so you can find it whenever you’re ready to cast on. And please drop a comment below if you make these. I read every single one, and I’m always cheering you on.
Notes from the pattern
- The main hook is 5.0mm (US H/8) for the body of the sock; the 4.5mm (US 7) hook is only for the cuff and is optional, used when a snugger fit is wanted.
- Place the locking stitch marker once the Setup round is complete, after the 37 stitches are established, to keep track of the round start through the gusset decreases.
- Check gauge before starting, since 16 stitches and 18 rows to 4 inches determines whether the ribbed rectangle finishes at the stated 3.5 inches wide by 8 inches long for the cuff.
- If extra durability at the heel and toe matters, choose a wool blend with some nylon content rather than a pure wool, as the sample yarn is wool-based without built-in reinforcement fibre.

Stitches you will use
- Working in the back loop only (BLO) Used through all 32 Foundation rows to build the ribbed cuff; keep the loop choice consistent row to row so the ribs stay straight.
- Slip-stitch selvedge edges Appears in every Heel Flap row, where a slip stitch bookends each side; work these slightly loose so the chain selvedge is easy to pick stitches up into later.
- sc2tog gusset decreases Used in the Gusset decrease rounds on either side of the instep; keep the decrease placed exactly at the marked points so the gusset narrows evenly.
Troubleshooting
The cuff feels stiff rather than stretchy once the ribbed rectangle is finished.
This usually means the back loop only was missed on some rows, flattening the rib; check each row of the Foundation section was worked BLO, not through both loops.
The edges of the heel flap look loose or gappy where stitches need to be picked up later.
The slip stitches at the start and end of each Heel Flap row were likely worked too loosely; tighten them slightly so the selvedge forms a firm chain edge.
The gusset area puckers or sits unevenly around the heel.
This points to an uneven pickup along the heel flap sides in the Setup round; recount to confirm exactly 8 stitches were picked up along each side before continuing.
Substituting yarn
- Cotton-blend, worsted weight (category 4)
- Produces a firmer, less elastic rib than the wool blend; the hook size can usually stay the same, but the cuff will stretch less over the ankle.
- Wool-nylon blend, fingering or sock weight
- Makes a noticeably thinner sock; the hook would need to drop well below 5.0mm, and the row and round counts given here would no longer match the stated gauge or finished length.
- Acrylic, worsted weight (category 4)
- Keeps the same 5.0mm hook and gauge as the wool blend but gives a less breathable fabric; without nylon content, reinforce the heel and toe separately if durability is a concern.
Washing and care
- Hand wash the finished socks in cool water with a wool-safe detergent, then press out excess water without wringing, since the wool blend can felt under heat or agitation.
- Reshape the socks flat to their finished dimensions and dry them laid out rather than hung, then store folded flat to keep the ribbed cuff from stretching out of shape.

FAQs
Questions
How much yarn is needed to make both socks?
The pattern calls for about 200 yards per sock, so roughly 400 yards total for the pair. One large skein with at least that yardage can usually complete both socks without a second ball.
Why is the cuff made as a flat ribbed rectangle instead of worked in the round?
Working the Foundation rows back and forth through the back loop only is what creates the vertical ribbing; this flat strip later forms the cuff before the sock continues as a tube. It is a standard way to get knit-style ribbing in crochet.
What is the stitch marker used for in this pattern?
A locking stitch marker is recommended once the Setup round reaches its full 37 stitches, to mark the start of the round through the gusset decrease rounds. This makes it easier to track where each decrease round begins and ends.
Is nylon-content yarn required, or is the wool blend shown enough?
The sample is made in a plain wool blend and works fine for warmth and general wear. Nylon content is only suggested as an option for extra strength specifically at the heel and toe, not as a requirement for the rest of the sock.
