Most "my merino socks wore out" stories are really washing stories. Merino is a resilient fibre, but heat and harsh detergents break it down. Five rules keep a good pair going for years:
1. Wash cold, gentle cycle
30°C or below. Heat is the enemy — it weakens wool fibre and shrinks it. A normal machine's wool or gentle setting is fine; merino-blend socks don't need hand washing.
2. Turn them inside out
Pilling happens where fabric rubs. Washing inside out protects the outer face and lets the sweat-facing side get the actual clean.
3. Skip fabric softener and bleach
Softener coats merino's scales and kills its moisture-wicking. Bleach dissolves protein fibre — and wool is protein. A mild or wool-specific detergent is all you need.
4. Air-dry, never tumble
The dryer is where most wool damage happens. Merino dries fast on a rack — usually overnight.
5. Wash less than you think
Merino resists odour, so airing socks overnight often resets them. Fewer washes means longer life — many wearers get two to three comfortable wears per wash outside summer.
Bonus: rotate your pairs
Wool fibre recovers its loft between wears. Rotating three pairs doesn't just spread the wear — each pair genuinely lasts longer than a third of one hammered pair.

FAQs
Can you tumble dry merino socks?
No — dryer heat weakens and shrinks wool fibre and degrades elastic. Air-drying overnight is faster than you'd expect.
How often should you wash wool socks?
Less than cotton. Air them overnight between wears; wash after two to three wears in mild weather, or after any sweaty day.
Why are my merino socks pilling?
Friction — usually from washing right-side-out with rough fabrics, or abrasive shoes. Wash inside out, cold, with like fabrics, and pilling stays minimal and can be gently removed with a fabric shaver.
