Frequently Asked Questions
Are merino socks better than cotton?
For cold, wet or multi-day use, yes. For warm indoor wear and for durability, a cotton blend is the better and cheaper choice.
Do merino socks itch?
Fine merino usually does not, because the fibres are thin enough to bend against the skin instead of pricking it. Coarse wool is a different experience.
Can merino socks go in the dryer?
No. Heat and tumbling felt the fibre and shrink the sock permanently. Cool hand or machine wash and air dry.
Which is better for grip socks?
Cotton. The sole has to hold a grip pattern through washing and abrasion, and cotton blends are stronger and cheaper for that job.
Why are merino socks so expensive?
The yarn costs several times more than cotton, and the fine fibre requires gentler processing. The price reflects the fibre, not the brand alone.
Merino socks regulate temperature and stay warm when damp; cotton socks are cheaper, more durable under abrasion and better for warm indoor wear. For hiking in cold or wet conditions merino wins. For studio, gym and everyday socks a cotton blend lasts longer and costs less.
The Two Fibres Side by Side
Merino is a fine wool from a specific sheep breed; the fibres are much thinner than standard wool, which is why merino does not itch the way coarse wool does. Cotton is a plant fibre, stronger when wet, and cheaper at the yarn stage. The performance differences all follow from that.
| Property | Merino | Cotton |
|---|---|---|
| Warmth when damp | Retains heat even wet | Loses insulation when wet |
| Moisture handling | Absorbs and releases vapour; stays dry-feeling | Absorbs and holds water; dries slowly |
| Odour | Naturally resistant; can be worn several days | Holds odour once damp |
| Abrasion | Softer fibre, wears faster at heel and toe | Stronger; longer life under hard wear |
| Cost | Several times the yarn cost of cotton | Low |
| Care | Cool wash, no dryer, no softener | Easy; tolerates 40 degrees |
Where Merino Is the Right Answer
Merino is the right choice wherever the foot will be cold or wet for hours. Hiking, winter running, cycling in cold weather and multi-day trips are the classic cases: a damp cotton sock in a cold boot is the fastest route to a blister and to cold feet, while merino keeps insulating. Merino also resists odour, which matters on trips where socks cannot be washed daily.
The trade-off is durability and price. A merino sock worn daily in a shoe will thin at the heel sooner than a cotton blend, and the yarn costs several times more. For a brand, that means merino belongs in a performance or outdoor range where the customer expects to pay for it.
Where Cotton Is the Right Answer
Cotton blends are the right choice for studio, gym and everyday socks. Our main studio construction is 85% cotton with 10% nylon and 5% spandex: the cotton gives the feel against the skin, the nylon takes the abrasion at the heel and toe, and the spandex holds the cuff. That combination survives repeated washing better than merino at a fraction of the cost.
Cotton is also the better base for grip socks. The sole carries a printed or moulded pattern that has to survive washing and friction, and a stronger fibre holds it more reliably. Merino grip socks exist, but they are a niche product for cold-weather studio use, not a volume line.
Blends Are Where Most Products Land
Very few commercial socks are 100% of either fibre. A merino sock is usually merino blended with nylon for strength and spandex for fit; a cotton sock is usually cotton with nylon and spandex. The blend percentages are what determine the price and the life, so they belong in the specification rather than the marketing copy.
Our standard constructions are listed in our material guide, and the full specification format is in our tech pack guide. For a comparison against plant-based regenerated fibres, see our bamboo vs cotton comparison.
Care Differences That Affect Returns
Merino needs cool washing and no dryer; heat and agitation felt the fibre and shrink the sock permanently, and that failure is not recoverable. Cotton is more forgiving but still loses shape in a hot dryer, and a cotton sock labelled for machine drying will come back smaller than it went out.
If a range mixes both fibres, the care labels must differ by product. A single care instruction across a mixed range is one of the more common causes of complaint, because the customer follows the label and one of the two products cannot take it.
What to Specify When Ordering
For a merino range, state the merino percentage and the micron range if your supplier offers a choice; both affect price and feel. For a cotton range, state the base percentage, the reinforcing fibre and the elastic percentage. In both cases, state the knit weight and the intended use, because a hiking sock and a studio sock are different products even when the fibre line looks similar.
Minimum order for custom runs is 50 pairs per size per design, with samples in 5-9 working days. A sample worn for a real session, washed once and inspected at the heel, settles more questions than a specification sheet.
