These socks are easily the best I have ever owned. I find myself wanting to wear them in nearly every situation. They are always my preferred socks when wearing business formal or business casual attire. However, I now want to wear them even when I go out for long walks or hikes, and even when I am working out. The only reason I don't have more is because they are relatively expensive compared to other socks. They are definitely worth the price though, especially considering the lifetime guarantee. I have not needed to take advantage of the lifetime guarantee yet, so I can't speak as to how those claims are handled.
