To provide an insole having versatility to be applied to various kinds of shoes and having a projection for preventing forward slip, wherein the shape of the projection has few risks of giving a user a sense of disorder when the sole is used.
The insole 0101 includes a base 0102 in contact with at least part of the sole of a foot, and the projection 0103 used as held between the big toe and the second toe of the foot. The shape of the projection 0103 as observed from a cross-section approximately parallel to the base is vertically long such that the transverse length of the foot is shorter than the longitudinal length connecting the heel side and the toe side of the foot, and is a teardrop-shape becoming narrower toward the toe side of the foot.
