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 initiate a claim, visit our Warranty page, fill out the form, and mail your laundered socks back to our Vermont headquarters. We will issue you a credit to select a brand-new pair.
Where are Darn Tough socks manufactured?
Every single pair of our socks is knit in our own mills located in Northfield, Vermont. We take pride in being American-made and supporting our local community.
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 wash my socks to ensure they last?
We recommend machine washing your socks on a cold, gentle cycle with the socks inside out. Tumble dry on low or air dry to maintain the integrity of the fibers.
How long does shipping take within the United States?
Standard shipping typically takes 3-7 business days. We also offer expedited shipping options at checkout if you need your performance socks sooner.
