Frequently Asked Questions
Everything you need to know about the world's most durable socks.
What does the Unconditional Lifetime Guarantee cover?
Our guarantee is simple: if our socks aren't the longest lasting socks you've ever owned, you can return them for another pair. No strings, no conditions, for life.
How do I process a warranty claim?
To start a claim, visit our Warranty page to fill out a form. Once submitted, you will receive instructions on how to ship your laundered socks back to us for a replacement credit.
Where are Darn Tough socks manufactured?
Every single pair of our socks is designed and knitted in our mill in Northfield, Vermont. We are proud to be American-made.
What materials do you use in your socks?
We primarily use premium Merino Wool for its natural moisture-wicking and antimicrobial properties, blended with Nylon and Lycra Spandex for durability and a perfect fit.
How should I care for my socks to ensure they last?
We recommend machine washing your socks on cold or warm inside out. Tumble dry on low or hang dry. Avoid bleach and fabric softeners to maintain the fiber integrity.
How long does shipping take for domestic orders?
Standard shipping typically takes 3-7 business days. You will receive a tracking number via email as soon as your order leaves our Vermont warehouse.
