Darn Tough come with a lifetime warranty. If you get holes in them, you mail them back and they ship you a new pair. Just beware of counterfeits. I have 4 pair and will only wear them to work where I'm in boots and on my feet climbing ladders and shit for 12 hour shifts. My feet sweat a ton which used to cause red, itchy, gross feet. Now my feet are pretty normal. Is Darn Tough the only brand that works? Almost certainly not, but they also have that warranty that you seem to need. Each pair is like $20 because of that, but if you hike or work long hours on your feet, I think it's a worthwhile investment.
