Darn Tough runs snug for performance. Smartwool fits more relaxed. Neither is better—just different preferences.
Price
Similar price point. The real cost difference is in replacement frequency due to durability.

The Verdict
These are different tools for different jobs. Darn Tough is for hard use where durability matters. Smartwool is for comfort-first situations where longevity is secondary.
Choose Darn Tough if you hike regularly, work on your feet, want to buy once, or value the lifetime warranty peace of mind.
Choose Smartwool if you prioritize plush comfort, want a relaxed fit, use socks primarily for casual/lounging, or value wide retail availability.
Most BIFL-minded buyers should choose Darn Tough. The lifetime warranty and superior durability make it the clear value play. But if you're buying socks primarily for comfort rather than performance, Smartwool is excellent.
Frequently Asked Questions
Is Darn Tough really more durable than Smartwool?
Yes, significantly. Darn Tough's 36% nylon content and dense knit construction means they last 2-3x longer than Smartwool in heavy use. Multiple thru-hikers report Darn Tough lasting entire long trails while Smartwool develops holes.
Why did Smartwool reduce their warranty?
After VF Corporation acquired Smartwool, they reduced the warranty from lifetime to 2 years. This reflects both business decisions and the reality that Smartwool socks are designed for comfort rather than extreme durability.
Can I wear Smartwool for hiking?
Absolutely. Smartwool makes excellent hiking socks. They're just not as durable as Darn Tough for heavy, frequent use. For occasional weekend hiking, Smartwool is perfectly fine.
Which is better for everyday wear?
Smartwool's softer feel makes it more pleasant for casual everyday wear. Darn Tough's firmer construction is better if you want one sock for both hiking and everyday use.
