Focused guides
Merino socks and ski socks have their own pages with the details buyers ask about.
Buyer's guide
Warmth comes from trapped air. A terry-loop sock has thousands of small loops on the inside that hold warm air against the foot, and a brushed interior does the same with a soft raised pile. Wool and merino add warmth even when damp and resist odour, while acrylic gives bulk and colour at a lower price. Polyester thermal blends dry fast, which matters for active use.
The right weight depends on the use. A light thermal sock suits city winters and layered boots, a mid weight suits hiking and outdoor work, and a heavy full-terry sock suits cold storage, ski and deep winter.
Warm mid and heavy weight socks for trail and camp.
Thermal socks for cold storage, construction and outdoor trades.
Patterned wool-blend socks in gift boxes.
Own-label winter multipacks.
Compare
Warmth comes from the yarn and the construction together. This is how the main builds compare.
| Build | Warmth | Best for |
|---|---|---|
| Brushed interior | Light to mid | City winters, layered boots, homewear |
| Terry loop, wool blend | Mid to heavy | Hiking, outdoor work, cold sites |
| Merino blend | Mid | Hiking and multi-day wear; warm when damp and odour-resistant |
| Heavy full terry | Heavy | Cold storage, ski and deep winter |
Merino and wool
Merino is a fine wool: its thin fibres feel soft rather than itchy and it keeps the foot warm even when damp. It also resists odour, so merino socks can be worn for several days on the trail. Pure merino is fragile, so socks use merino blended with nylon for strength and elastane for stretch. A lower merino share brings the cost down and adds durability.
Wool blends with acrylic or cotton offer warmth at a lower price, and they take bright colours and jacquard patterns well. See our merino wool socks page for the details.

Customization
Every part of the sock is yours to specify. Our design team sends a mockup of each logo and label placement, and every detail is confirmed in a tech pack before sampling.
Merino or wool blend, acrylic or brushed polyester.
Light, mid or heavy, with terry or brushed interior.
Crew, over-the-calf or knee-high, graded across sizes.
Jacquard pattern, woven labels, hang tags and sleeves.

The minimum order is 50 pairs per design.
A full terry-loop knit in a wool or merino blend is the warmest. Brushed interior socks are softer and lighter; polyester thermal blends dry fastest.
Yes. Over-the-calf ski socks with cushioned shin, heel and toe are on our ski wear pages.
Yes. Nordic, striped and logo patterns are knitted in, and heavier socks show the pattern in a chunky, textured way.
Fine merino fibres feel soft on the skin. Coarser wool can itch, so we suggest a fine merino for a sock worn against bare skin.
