An improved sock or slipper sock comprising a toe portion for covering the toes of a foot, a continuous calf portion for surrounding a calf, and a slit, slot or opening located between the toe portion and the calf portion is disclosed. The slot terminates, at one end, adjacent to the toe portion and terminates at the other end, adjacent to the calf portion. In a preferred embodiment, the slit is buttonhole stitched for durability. When the sock is first put on a foot, the calf portion is held open and gently slid over the toes, the foot and up the calf where it is released and gently grips the calf. The toe portion is then manipulated to cover the toes of the foot. The slit opens, as necessary, to accommodate any dressing that might be anywhere on the foot. When the dressing needs to be changed, the calf portion remains in its position around the calf, or is adjusted downwardly somewhat, and the toe portion of the sock is removed from toes, leaving the sock attached to the person, about his or her calf. The sock is then manipulated to expose the old dressing, through the slot, the dressing is changed and the toe portion is repositioned over the toes.
