Frequently Asked Questions
Is it worth paying $25 for Darn Tough over $15 for Kirkland?
For heavy users, absolutely. Darn Tough's lifetime warranty and superior durability means lower cost-per-wear over time. For occasional use, Kirkland is fine.
Which Darn Tough model should I start with?
The Hiker Micro Crew (1466) is the most versatile choice. It works for hiking, everyday wear, and work. Start there, then add specialized models as needed.
Darn Tough or Farm to Feet?
Both have lifetime warranties and similar quality. Darn Tough is more widely known and available. Farm to Feet has 100% US supply chain if that matters to you.
How many pairs should I buy to start?
3-5 pairs is ideal. This allows rotation (extending lifespan), ensures you always have clean socks, and covers different use cases. Many people never buy socks again after one good purchase.
