This is the second set of these socks that I have purchased. I bought them the first time around because of the high cotton content (yes, I am biased towards cotton). I was not disappointed. The socks held up really well. I never got holes in them even though I wore and washed them at least twice a week for over a year. The only problem was, with wearing them that often, they became a bit faded and the stretch in them sort of wore out after a couple years. Then again, these are a very good price and if they will last heavy work for two years, they are well worth it.
