For what it's worth, I have my same 7 pairs of Rocky S2V boot socks that I bought 5 years ago. Wear a pair every day for work, a pair for each day of the week. Absolutely love them, they still have enough elastic to hold themselves up and they still form to my feet. I have yet to toss a pair due to holes or wearing em too thin... not sure what I'm doing wrong and why they are not breaking down yet but dang I like those socks.
