Brilliance without schooling. The Oxford Sock is complete with a full rib from welt to toe, for those who appreciate a new-fashioned take on a traditional dress sock. This is the longest sock we currently offer. Knit with 3 plies of lightweight Egyptian Mako Cotton, spun from a long staple fiber that's smoother, finer, and stronger than other cotton. Originating from a lost garden of neglected cotton plants, Mako plants are now grown in a small part of the Nile Delta where they are picked by hand to preserve the delicacy of the plant.
