Indestructawool™
technology
Designed to break limits
Our new, patent-pending Indestructawool™ technology isn’t just something we added to our performance socks, but a whole new way to build them. We’ve developed a new, much more durable knitting technique that enables 30% more choss-filled approaches, gut-wrenching descents, and paradigm-shifting summits. You push yourself to new limits, so we thought we’d push our Smartwool® PhD® socks to new ones too.
