DARN TOUGH !! https://darntough.comThat's all you need to know. Have a look at their website and learn a bit about the different lengths, cushioning, and styles. They have everything from dress socks to socks for climbing Mount Everest. Then you can buy them on Amazon or wherever.
At first I balked at paying $20+ for a pair of socks, but I will tell you, they are
worth it! They are among the best products of any kind I have ever bought. Three or four years later they are still very comfortable, look great, and do not show the slightest sign of wear! They have a lifetime guarantee, and I've heard many people say they will last decades.
Being made of wool they do not pick up odors, you can even get away with wearing them twice or three times between washes. I do not normally do this, however, I try to pack very light when traveling overseas, and have had no qualms about bringing a dozen pairs of socks for a three-week trip (I HATE doing laundry when traveling).
If I could find other garments made to these standards, I would definitely buy them!
EDIT: I read a comment above about not enough cushion, but, even the middle-of-the road levels of cushion are very cushiony. If you buy full cushion, it will be a crazy amout of cushion, at least in my experience.
