This is the second pair of Darn Tough's I have bought. I enjoy the fact that they are lightweight. I hike a lot. This is a thinner material than the first pair I bought and allow my feet to breath easy. I have noticed with DT that, although my feet stay dry, they still feel moist, if that makes sense. But, it wouldn't stop me from buying a 3rd or 4th pair for hiking. I like the fact that with Darn Tough one can wear these multiple days in a row and your feet do not smell when you take your shoes off. I have yet to trail test these lighter weight socks, which come up about mid-calf on me, so I am not sure how well they will do after a long day of hiking. I have a few questions, like will they make my legs hurt as my legs begin to swell throughout the day from being on them? Will they rub the plantar part of my foot after a long hike and causes pain? Trail testing tomorrow. But, Darn Tough's guarantee is hard to beat. Pricey, yes, but well worth the money.
