The short version

Darn Tough is the hiking sock with an unconditional lifetime guarantee. We calculated the long-term value proposition and compared construction quality to Smartwool.

Who it's for

Buy this if: Regular hikers who burn through hiking socks annually and want to stop replacing them.

Skip this if: Occasional hikers who wear socks infrequently — the lifetime guarantee earns its value through repeated use.

In practice

Lifetime Guarantee Math

Average hiker replaces socks every 1.5-2 years. At 10 years: 5-7 new REI pairs at $16 = $80-112. At 10 years: 1 Darn Tough pair at $25 + free replacements = $25 total. The guarantee makes Darn Tough the cheaper sock at any regular hiking frequency.

What we loved
+ Unconditional lifetime guarantee — worn through after 2 years? New pair, free+ 73% merino for odor control over multiple days+ Vermont manufacturing with consistent quality control
What we'd change
– $25/pair vs. REI at $16 — 55% premium– Slightly less cushioning in midfoot vs. Smartwool PhD series
