I have one pair of Darn Tough. They're only maybe three years old, plus I don't really like them for running, so I can't really comment on wear, but they do seem pretty tough. A lot of why I don't really like to run in them is that the fabric is so dense, so even though they're heavy, they don't really cushion or have a lot of stretch. They seem like they would stand up to a lot of abuse.


We probably ought to move this conversation to the Wool Weenies thread, it's past the season for reviving that.
