Darn Tough is an easy one for Flip-Flop because they have a lifetime warranty! Yes, lifetime. Meaning you’ll never have to pay for another pair of socks once you switch over to Darn Tough; as long as you don’t burn them, let the dog eat one, or lose one to the dryer monster. If you get a hole in them from normal wear and tear they will replace them for you. Check out Darn Tough’s warranty here.
Smartwool is Caveman’s favorite wool sock brand. They do not have a lifetime warranty, but do come in many different styles and thicknesses compared to Darn Tough. Caveman has tried Darn Tough and says that his feet get too warm in them, which is why he prefers Smartwool for their versatility.
