Why the coach picked it
- $16.50 vs. $23 a pair, and $14.85 each if you buy four or more singles. Over a drawer of seven pairs that's real money.
- Both brands take worn socks back. Darn Tough's lifetime guarantee covers holes and accidental damage, no receipt needed, but you mail the socks back yourself by the cheapest method and the replacement comes as site credit. Bombas says you can return or exchange 'in any condition', with no end date stated, and advertises free returns.
- Bombas is a midweight calf sock with cushion in the impact zones and arch compression. Darn Tough's run sock is ultra-lightweight, cushioned underfoot with terry loops.
- The calf height covers more shin than a micro crew. That's the sock you want on rope climbs and deadlifts.
- Darn Tough is 51% merino and says if these aren't the longest-lasting socks you've owned, return them for another pair. Bombas lists no fiber content and makes no durability claim on its product page. If merino matters to you, that's the Darn Tough's edge.
When the other one is the right call
If you run more than you lift, or want merino for odor and warmth, buy the Darn Tough. The micro crew is a running sock, and it's the one Darn Tough built for that.
