These socks feel good, but they have a terrible chemical smell that repeated washing does not help.  I've washed some pairs as much as three times and they still smell bad.  I'm not sure how they were made or what is in them, but they stink.  I will wear them, but would never buy them again.

Update--December 22, 2012--These socks still have a faint chemical smell, after all this time.  The feel good and the fit is great, but the smell is still there, even after putting a fragrant bar of soap in my sock drawer.  It really makes me wonder how and where they were made.
