A sock is provided having a first compression areawhich raises the compressive force in a wale direction from a position A behind the toe area of a sole portion of the sock to a position C which includes the boundary between an arch portion B and a heel portion, a second compression areaprovided on the periphery to raise the compressive force in a course direction at the position A behind the toe area, a third compression areaprovided on the periphery to raise the compressive force in a course direction at an ankle portion D, and a fourth compression areaprovided on the periphery to raise the compressive force in a course direction from the position C which includes the boundary between the arch portion B and the heel portionto a position E at the base of the instep portion. The advantageous effect of protecting and restoring the shape of the longitudinal plantar arch is produced by the various compression areas, thereby stabilizing the position of the various compression areas while the sock is worn.
