Short answer: the best alpaca sock is the one matched to what you actually do in it. For everyday wear, look for no tight elastic at the top and around 60% alpaca. For work boots and cold ground, look for a heavier gauge with a cushioned sole, even if the alpaca percentage is lower. For trainers and warmer days, look for a fine, high-alpaca low-cut. Below is our entire range with the real fibre content of each, so you can compare rather than guess.
What actually matters when you buy alpaca socks
1. Fibre diameter, not the word "alpaca"
What you feel against your skin is fibre diameter. Above roughly 30 microns, fibres of any kind start to trigger the nerve endings that make a sock feel prickly. Fine alpaca sits well below that line.
This is why people who cannot wear ordinary wool often get on fine with alpaca — it is the fineness doing the work, not the species. A coarse alpaca sock will prickle exactly like a coarse wool one. Be sceptical of anyone who tells you alpaca is prickle-free as a rule.
2. Alpaca percentage, and why more is not always better
A sock knitted entirely from alpaca would not hold its shape past a few wears. Nylon gives it structure, acrylic adds resilience, and a small amount of elastane keeps the cuff where you put it.
Our range runs from 42% to 86% alpaca, and the highest number is not the best sock. The 86% is a fine low-cut for trainers. The 42% is the warmest, heaviest sock we sell — because that warmth is coming from gauge and cushioning, not from the percentage.
What you should insist on is being told the number at all. If a seller will not publish the composition, that tells you something.
3. Weight, matched to the boot
- Lightweight to midweight — everyday shoes, office, warmer months. Dries faster, works across more of the year.
- Midweight — general outdoor use and walking boots.
- Heavyweight — work boots, cold ground, standing still in winter.
A thick cushioned sole is wonderful in a boot in July and miserable in a shoe in January. Getting the weight right matters as much as getting the fibre right.
4. How it handles moisture
Alpaca has a moisture regain of around 8%, against roughly 16% for sheep's wool. In plain terms: it takes up less water before it starts to feel damp, and it dries faster afterwards.
That is a measured property of the fibre, not a performance promise. But it is the practical reason people reach for alpaca on the second day of a walk.
5. The cuff
A sock that leaves a ring around your calf at the end of the day is gripping, not fitting. The health sock design solves this by holding itself up through the knit rather than through a tight elastic band. If you have ever peeled your socks off at night and rubbed the mark out of your leg, this is the detail to look for.

Which one should you buy?
- On your feet all day, indoors or in shoes — the Alpaca Health Sock, $33. No tight elastic, made in Australia. This is the one most people buy first.
- Work boots, cold ground, long days — the Ultimate Boot Socks, $49.50. Heaviest gauge, thickest cushioned sole. Not a daily steel-cap sock; alpaca will not take that kind of abrasion.
- Walking and hiking — the Premium Alpaca Outdoor Hiker Socks, $44. Full terry with the heel, sole and toe reinforced where boots wear a sock out, and an elastic band through the arch so it does not bunch.
- Trainers or warmer weather — the No Show Sock, $49.95, at 86% baby alpaca the highest fibre content in the range.
- Cold feet in bed — the Bed Socks, $38.50. Ribbed, ankle length, nine colours. Made to be worn in bed, not in boots.
- A gift — the Sock Drawer Reset, $119. Three pairs in three weights: health sock for every day, hiker for the trail, boot sock for the heavy days. It is $15 less than buying the three separately, and it is the easiest way to find out which weight suits you.
Where these socks come from, and where they don't
Most of the socks we sell are knitted in Peru, which is where alpaca has been spun and knitted for centuries and where the best of it is still done. We treat that as a quality mark, not a disclaimer.
The two health socks are made in Australia by Humphrey Law, knitted, dyed and finished here.
Our own fibre is a separate thing and we do not blur the two. The raw fleece, yarn and carded bumps are grown on our own herd at Mulgoa in western Sydney, shorn here, sold undyed, and we can tell you which animal grew it. The socks are not off our animals, and we are not going to pretend otherwise. What we will always tell you is the composition, the country and the micron where we have it.
What we won't claim
Alpaca gets sold on some big promises: that the fibre is hollow and traps air, that it regulates your body temperature, that it is a set percentage warmer than wool. We use none of them, because none of them hold up. The Australian Alpaca Association's own fibre booklet describes the hollow-fibre insulation claim as without foundation.
What we will stand behind: it is fine, it holds less moisture than sheep's wool, it dries quickly, and it wears well. That is enough to be going on with.
