Best Yarn for Knitting Socks: A Practical Guide
If you’ve ever wondered what makes a good sock yarn, you’re not alone. With so many fibre blends, weights and bases available, choosing the best yarn for knitting socks can feel surprisingly complicated.
The truth is, the “best” sock yarn depends on what you want from your finished socks. Are you knitting hard-wearing everyday socks? Soft, luxurious bed socks? Or socks with crisp stitch definition for showing off textured patterns?
For many knitters, a merino and nylon blend strikes the perfect balance of softness, durability and elasticity — which is exactly why we love an 85% Superwash Merino / 15% Nylon blend for our Market Town Yarns Squishy Sock yarn.
Why Fibre Content Matters
A good sock yarn needs to do several things well:
- Stand up to friction and wear
- Stretch comfortably around the foot
- Bounce back into shape
- Feel soft enough to enjoy wearing
That’s where fibre blends come in.
While 100% wool can make beautiful socks, many knitters prefer a blend that includes a reinforcing fibre such as nylon for extra durability. This is especially useful for heels and toes, where socks naturally take the most wear.
Why 85/15 Merino Nylon Is So Popular
One of the most popular choices for sock knitting is an 85% Superwash Merino and 15% Nylon blend — and for good reason.
It offers:
- Softness from fine merino wool
- Strength from nylon
- Excellent stitch definition
- Good elasticity and recovery
- Durability for everyday wear
It’s a blend we love for our Market Town Yarns Squishy Sock yarn because it combines comfort and practicality in a way that works beautifully for socks.
Superwash or Non-Superwash?
For many knitters, superwash wool is a practical choice for socks because it is easier to care for and generally more resilient in regular use.
Non-superwash sock yarns certainly have their fans, particularly for traditional woolly socks, but for many modern sock knitters, superwash blends offer an appealing mix of convenience and performance.
Does Yardage Matter?
Yes — and it’s often overlooked.
A typical 100g skein of 4-ply sock yarn at around 400 metres is often enough for a standard adult pair of socks, although larger sizes, longer legs or textured patterns may need more.
Checking yardage before choosing a yarn can save surprises later.
Everyday Socks or Luxury Socks?
This is worth considering before you cast on.
For everyday socks, durability often comes first.
For softer lounging or bed socks, you may lean more towards luxury fibres and softness.
The best sock yarn depends partly on how you plan to wear them.
