Smartwool FAQ
Common questions about Smartwool
Learn more about what makes Smartwool unique.
How do I wash my Smartwool?
Machine wash cold on gentle cycle, tumble dry low or lay flat to dry. No bleach, no fabric softener — the softener coats the fibres and kills merino's natural moisture-wicking ability.
Why wear merino wool socks?
Merino wool naturally regulates temperature, wicks moisture, and resists odour — your feet stay dry and fresh whether it's -20°C or a summer hike. Unlike synthetic socks, merino won't smell after a full day.
Are Smartwool socks worth it?
Smartwool blends the warmth and odour-resistance of merino with athletic tailoring, so one pair handles cold mornings, hikes, and long days while staying fresh. They sit at a premium, but the comfort and performance earn it for people who are hard on socks.
What is Indestructawool?
Indestructawool is Smartwool's durability technology — it reinforces the highest-wear zones (heel, toe, ball of foot) with a denser merino-and-nylon blend, adding strength exactly where socks usually thin out, without extra bulk.
