The present invention provides a sock that can be knitted by a versatile knitting machine, supports a lateral arch and a vertical arch of a foot, holds the heel easily, and does not hinder the detachability of the sock. A sock having a toe portion 31 covering a toe portion of a foot, a heel portion 32 covering a heel portion of a foot, and a foot main body 33 disposed between the toe portion and the heel portion. The body part is composed of an area A on the toe side, an area B on the heel side, and a central area C disposed between the toe side area and the heel side area, and the central area is an instep portion C1 that covers the instep. And has a sole portion C2 covering the sole of the foot, the toe side region is a weak pressure portion with a weak pressure, and the heel side region is a medium pressure portion with a stronger pressure than the weak pressure portion, The instep portion in the central region is a strong pressure portion having a stronger pressure than the medium pressure portion, and the sole portion in the central region is the strongest pressure portion having a stronger pressure than the strong pressure portion. [Selection] Figure 1【課題】汎用性の編機で編成でき、足の横アーチおよび縦アーチもサポートするとともに、踵をずれ難くホールドし且つ靴下の着脱性を妨げないような靴下を提供する。【解決手段】足の爪先部分を覆う爪先部３１と、足の踵部分を覆う踵部３２と、爪先部と踵部の間に配設される足部本体３３を有する靴下であって、足部本体は爪先側の領域Ａと、踵側の領域Ｂと、爪先側領域と踵側領域の間に配設される中央領域Ｃよりなり、中央領域は、足の甲を覆う足甲部分Ｃ１と、足の裏を覆う足底部分Ｃ２を有し、爪先側の領域は着圧が弱い弱圧部であり、踵側の領域は弱圧部よりも着圧が強い中圧部であり、中央領域における足甲部分は中圧部よりも着圧が強い強圧部であり、中央領域における足底部分は強圧部よりも着圧が強い最強圧部である。【選択図】図１
