Familiarity: I've put it through the wringer
I use these bad boys for road and mountain cycling in the spring.summer/fall. They are the perfect height cuff for me...not tool tall, but taller than your standard, old school cycling sock. I go black, it lasts longer because you don't see dirt stains for mud spray or dust and grime when you are getting rad. At this point they are the only socks I'll buy to ride in, barring winter needs.
