Frequently Asked Questions
Everything you need to know about the world's most durable socks.
What is the Darn Tough Lifetime Guarantee?
Our promise 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 your socks manufactured?
Every single pair of our socks is knit in our own mills located in Northfield, Vermont, USA, ensuring the highest standards of quality and ethical production.
How should I wash and care for my wool socks?
For best results, 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.
What materials do you use in your socks?
We primarily use premium Merino Wool for its moisture-wicking and antimicrobial properties, blended with Nylon and Lycra Spandex for durability and a perfect fit.
How do I find the right size?
We provide a comprehensive size chart on every product page. Our socks are designed with a performance fit, meaning they should feel snug but comfortable without slipping or bunching.
