Most sock drawers are a cotton multipack bought without much thought. That's fine until you spend a full day on your feet in them. Here's what changes when you switch to wool, alpaca or merino, and one thing that doesn't.
1. Drier feet
Cotton absorbs sweat and holds it against the skin. Wool moves it away. Merino takes moisture into the fibre as vapour; alpaca wicks it to the surface to evaporate. Either way, less of it sits on your foot. More in our moisture-wicking socks guide.
2. Warm when damp
Wet cotton stops insulating. Wool keeps much of its warmth when damp, which is the difference between an uncomfortable walk home and a cold one.
3. Better temperature control
Wool insulates when you're still and breathes when you're moving, so feet swing less between cold and clammy. Merino is particularly good at this, which is why it works year-round.
4. Less smell
Odour comes from bacteria, and bacteria like damp. Keep the foot drier and there's less for them to work with. Wool socks can often be aired and worn again rather than washed every time. See how often to wash wool socks.
5. Fewer blisters
Blisters need friction and softened skin. Damp cotton supplies the second. A dry, well-fitted wool sock takes away much of the problem. More in our anti-blister socks guide.
6. Softer than you remember
The itchy wool sock is real, but it comes from coarse fibre. Alpaca and fine merino are a different thing. If you wrote wool off years ago, here's why it itched.
7. They last, if you let them
A good wool sock keeps its shape and cushioning far longer than a cheap cotton one. Wash it cool, skip the tumble dryer, and it'll see you through several winters.
The thing that doesn't change
You'll read that wool socks are plastic-free. Ours aren't, and neither is any wool sock built to last. Pure wool wears through at the heel within a season, so there's nylon in there for strength and a little spandex so the sock stays up. Our alpaca socks are 74% alpaca, 23% nylon and 3% spandex.
So: far more natural fibre and far less plastic than a polyester sock. Not none. We'd rather say so.
The short version
- Cotton holds sweat; wool moves it.
- Wool stays warm when damp. Cotton doesn't.
- Fewer washes, fewer blisters, longer life.
- Alpaca for cold feet and sensitive skin; merino for year-round wear.
