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.
Where are Darn Tough socks manufactured?
Every single pair of our socks is knit in our Northfield, Vermont mills. We are proud to be American-made and family-owned.
How should I wash and care for my Merino Wool socks?
To ensure longevity, machine wash your socks in warm water on a gentle cycle with the socks inside out. Tumble dry on low or air dry. Do not use bleach or fabric softeners.
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.
What is your return policy for unused items?
We accept returns for a full refund on any unworn, unwashed items with original packaging within 90 days of purchase.
Why is Merino Wool better than cotton for socks?
Merino Wool is a technical fiber that excels at moisture wicking, temperature regulation, and odor resistance, keeping your feet dry and comfortable in both summer and winter.
