Old School Work Boot SocksThese socks combine the functional specs of classic work boot socks with a retro tube sock stripe design. The stripe is positioned slightly higher so it peeks out from the top of your boots. The sole is knit with a cushioned pile construction, helping to reduce fatigue even during long hours of wear. *Avoid using a tumble dryer, as it may cause shrinkage.
