Sock Yarns & Constructions
A sock is made of two things: the yarn it is knitted from and the knit structure it is knitted in. This page covers the sock yarns we use, from combed cotton and merino to bamboo viscose and recycled polyester, and the constructions that decide cushioning, grip, stretch and warmth.

Choosing a yarn
Which yarn for which sock
Almost every sock is a blend: a main fibre for feel, nylon for strength and a little elastane for stretch. The main fibre sets the character of the sock.
| Main fibre | Best for | Strengths | Watch out for |
|---|---|---|---|
| Combed cotton | Everyday, office, kids, workwear | Soft, breathable, easy to dye | Slow to dry, wears at heel and toe unless blended with nylon |
| Mercerized cotton | Dress and fashion socks | Sheen, deeper colour, smooth feel | Fine gauge is less cushioned |
| Merino wool blend | Hiking, winter, outdoor work | Warm when damp, tends to resist odour | Higher cost; needs nylon for strength |
| Wool/acrylic | Patterned winter and gift socks | Warm, colourful, lower price | Less breathable than merino |
| Bamboo viscose | Comfort and sensitive-skin socks | Silky, breathable, soft | Weaker when wet; must be labelled as viscose |
| Polyester/nylon | Running, gym, team and compression socks | Wicks sweat, dries fast, holds shape | Feels cooler and less natural than cotton |
| Recycled polyester | Sport and everyday ranges with a recycled claim | Performs like polyester with recycled content | The recycled share and certificate come from the yarn supplier |
| Acrylic | Bright pattern, plush and team socks | Wide colour range, soft, easy care | Can pill and holds less heat than wool |
Constructions
What the knit structure does
The same yarn behaves differently in different knits. Most socks combine several constructions in different zones.
-
Terry loop
Loops on the inside cushion the foot and hold warm air. Full terry is usually the warmest; terry zones sit in the heel, ball and toe of sport socks.
-
Rib
Stretchy columns at the cuff and arch keep the sock up and snug, and hold its shape after washing.
-
Jacquard
Two or more colours built into the fabric for stripes, patterns and logos, which do not crack or fade.
-
Mesh and grip
Open mesh lets a sport sock breathe over the instep, and silicone dots on the sole stop slipping on smooth floors.

FAQ
Sock yarns: frequently asked questions
Why are cotton socks blended with nylon and elastane?
Pure cotton wears through at the heel and toe and does not spring back. Nylon adds strength and elastane adds stretch and recovery, so the sock lasts and keeps its shape while still feeling like cotton.
Is bamboo viscose the same as natural bamboo?
No. Bamboo viscose is a manufactured cellulose fibre made from bamboo. It feels silky and breathes well, and in most markets it must be labelled as viscose (or rayon) made from bamboo.
Can you supply recycled or certified yarns?
Recycled polyester and organic or certified cotton yarn can be sourced on request, subject to availability. Certificates come from the yarn supplier for the order, and we do not claim a certification unless it can be documented.
Who makes the yarn, and who knits the socks?
The yarn comes from partner spinners. We knit, finish, inspect and pack the socks in our factory in Sialkot, Pakistan.
