Frequently Asked Questions
Everything you need to know about the world's most durable socks.
What does the Unconditional Lifetime Guarantee actually 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, and no expiration date.
How do I process a warranty claim for a worn-out pair?
To start a claim, visit our Warranty page, fill out the form, and mail your laundered socks back to our Vermont headquarters. Once received, we will issue you a credit code for a replacement pair.
What materials are used in Darn Tough socks?
We primarily use premium Merino Wool for its natural moisture-wicking and antimicrobial properties, blended with Nylon and Lycra Spandex for superior durability and a performance fit.
How should I care for my socks to ensure they last?
We recommend machine washing your socks on cold or warm cycles and tumble drying on low. Do not use bleach or fabric softeners, as these can damage the natural 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 socks sooner for an upcoming adventure.
Do you offer international shipping?
Yes, we ship to many countries worldwide. Please note that international customers are responsible for any customs duties or taxes incurred during the import process.
