The 5 Best Sock Yarns, Voted by Our Customers

Voted by sock knitters

5 yarns · 8 min read

A sock yarn has a harder job than any other yarn in your stash. It has to be soft enough to wear against the arch of a foot and tough enough to survive being walked on for years, then washed, then walked on again.

So we read through each and every review from knitters who have actually worn them — here are the five you couldn't stop talking about, including one that isn't wool at all and one you mostly use for everything except socks.

The short version

  • Cascade Heritage — the default: merino and nylon, and reviewers still wearing the socks years later.
  • Berroco Comfort Sock — the wool-free option, and the least expensive on the list.
  • Valley Charlemont — our house sock yarn, with silk in the blend for sheen.
  • Universal Bamboo Pop Sock — bamboo and cotton, for summer socks and light tees.
  • Cascade 220 Fingering — pure wool fingering, the colorwork favorite.
  • Curated from your genuine feedback and ranked by the yarns you loved most.

Key Takeaways

  • Nylon is the secret to socks that last: The pairs you're still wearing years later all have nylon in the blend.
  • No wool required: If wool isn't an option for you, the nylon and bamboo picks here knit up just as happily.
  • Sock yarn is the best value in the shop: One skein is a whole pair of socks — or a shawl, or the contrast color for an entire sweater.
  • Grab two colorways: Heels and toes in a contrast color wear longer and put your leftovers to work.
  • Most of it never becomes socks: Shawls, mittens, baby tees, and colorwork yokes fill your reviews just as often as socks do!

The 5 Best Sock Yarns, Voted By Our Customers

Best all-around sock yarn
Cascade Yarns Heritage Yarn - Superwash Merino 4 Ply

Cascade Yarns Heritage Yarn - Superwash Merino 4 Ply

Superwash merino and nylon, fingering weight

★★★★☆

$9.60

Priced to be knit, not stashed. It's the sock yarn you reach for most, and the nylon is why you're still wearing pairs from years ago.

“Great yarn at a great price.”

The socks I make with Heritage yarn are long lasting. I have worn them for years and still have no holes. The yarn feels soft and is easy to knit with. It doesn’t split.

“Warm and durable sock yarn”

This is the broken seed pattern I found on Ravelry. I usually use Heritage or Cascade Fingering weight yarn. They are both reasonably priced. I combine them with a variegated yarn which makes for an interesting design pattern. The trick is to knit with a zero or number one size needles so the design is more pronounced. Additionally, when a lace weight with mohair and silk is on sale, I will knit up a vanilla sock pattern on number three needles using the Heritage or Cascade fingering weight with the lace. They are the warmest socks ever. Mine last for quite a while, but I do not walk around the house in them because eventually they will wear out. I hand wash in Eucalan with tepid water and do not rinse out the natural lanolin of Eucalan, which will provide longevity. I am forever ordering more sock yarns and trying out new patterns, and Webs prices on Cascade and Heritage are fair but even better when they go on sale. Just thought I would share my socks with everyone. I have been using this yarn for many years.

I love the perfect color match. Winding was smooth—no glitches. I would purchase again for heel & toes of socks.

Best wool-free option
Berroco Comfort Sock Yarn - Nylon 3 Ply

Berroco Comfort Sock Yarn - Nylon 3 Ply

Nylon and acrylic, fingering weight

★★★★★

$4.75

The answer for anyone who can't wear wool, and the least expensive sock yarn on the list. Reviewers also hold it alongside fingering wool to add durability, and knit baby clothes out of it.

“Great affordable sock yarn”

I have a hard time finding sock yarn that’s not wool. I like the colors and it is fun to work with. It’s an affordable option for people who can’t use wool, and I’m always happy with the finished product. I have not used these yet, but I’m looking forward to it. I’ve used this yarn and probably some of these same colors before tho.

“Perfect yarn for baby clothes”

I'm not making socks, but as I'm allergic to wool, this yarn is perfect for my preference for knitting with thin yarn and skinny needles. I enjoy making baby dresses for girls and baby sweaters for boys as presents for newborns. I'm told the clothing wears well. Baby girl parents have communicated that the dresses become tops as their little girl grows. I don’t have any photos on hand, but I have a baby boy sweater in process.

“Great for durability and technique”

I'm using it for pairing with fingering wool for durability. The swatched piece resulted in the stitch count I was looking for. The colors blended well and the texture came out nice to the touch. Yes, my first time using this technique.

Best for special projects
Valley Yarns Charlemont Yarn - Superwash Merino 4 Ply

Valley Yarns Charlemont Yarn - Superwash Merino 4 Ply

Superwash merino, silk and nylon, 4-ply

★★★★☆

$13.12

Our house sock yarn has silk in the blend, which gives it a faint sheen and a smoothness you can feel in the skein. Reviewers save it for lace projects and for socks that are a gift rather than a chore.

“Great yarn, tricky pattern”

I appreciate the help in finding the yarn and the correct dye lot. I'm using it for a lace leaf sweater for my granddaughter. The pattern is giving me some problems, so I might find another pattern for this yarn.

Best for summer
Universal Yarn Bamboo Pop Sock Yarn - Bamboo Fingering

Universal Yarn Bamboo Pop Sock Yarn - Bamboo Fingering

Bamboo and cotton, fingering weight

★★★★★

$9.60

Bamboo and cotton, so it breathes rather than insulates — the sock yarn for warm weather and for people who overheat in wool. Reviewers also make remarkably light tees out of two or three balls.

“Beautiful yarn for a stylish tee”

I really liked the feel of the yarn as I was working a sweater, which only took 2 balls of the yarn. The sweater feels so light and cool. Since I bought 4 balls, I have enough to make a second sweater. It is a tee with a V-neck and short sleeves. It fits beautifully and I got a lot of questions about the yarn because it attracted a lot of compliments.

I like the fun colors and the bit of texture. I'm planning to make a crocheted blouse.

Best for colorwork
Cascade Yarns 220 Fingering Yarn - Wool Fingering

Cascade Yarns 220 Fingering Yarn - Wool Fingering

100% Peruvian highland wool, fingering weight

★★★★★

$4.60

100% pure wool with zero nylon—making it a dream for stranded colorwork. The fibers grip together naturally so your patterns lay perfectly flat, which is why reviewers load up their carts for full sweaters the second it goes on sale.

I bought enough for a sweater just in case. For the second time, the sale was great. I'm using it for a top down raglan.

A tip from the yarn wall: Knit your heels and toes with a strand of contrasting sock yarn held alongside the main color. It doubles the thickness exactly where socks wear through, uses up the leftovers you already have, and reviewers who do it report pairs lasting years longer than the ones they knit plain.

If you are knitting your first pair of socks, start with Cascade Heritage. It is priced so a mistake doesn't hurt, the nylon means the pair will outlast your learning curve, and the color range is wide enough that the second pair is more fun than the first.

Frequently Asked Questions

What makes a yarn a sock yarn?

Two things: a fine gauge — fingering or 4-ply, so the fabric is thin enough to fit inside a shoe — and usually a nylon content of 20 to 25 percent, which is what keeps heels and toes from wearing through.

Can I knit socks without wool?

Yes. Berroco Comfort Sock and Universal Bamboo Pop Sock on this list are both wool-free, and reviewers who cannot wear wool use them exactly as they would a merino blend.

How many skeins do I need for a pair of socks?

One 100g skein of fingering weight covers an average adult pair with a little left over. Larger feet, taller cuffs or a textured pattern can push you into a second skein, so buy two if you are between sizes.

Is superwash necessary for socks?

It is practical. Untreated wool socks felt in a machine, so unless you plan to hand wash, choose superwash — or an entirely wool-free yarn. Reviewers overwhelmingly choose the washable option.

What else can I knit with sock yarn?

Almost anything light: shawls, mittens, baby garments, summer tees, and the contrast color in a stranded yoke. Our reviewers use sock yarn for non-sock projects at least as often as for socks.

How were these five chosen?

You chose them. We read through each and every review on the sock and fingering weight yarns we carry, kept the ones with a real track record, and left out anything that's out of stock. One favorite, Paintbox Socks, is sold out as we publish, so it isn't on the list.
