Abstract

A concave portion (31) for reducing the weight load of the wearer acting on the big toe (f1) is formed at a region in an insole (3) of a shoe (1). The region corresponds to a first site ranging from the ball (f1a) of the big toe (f1) to the tip of the toe. Further, at a region corresponding to a second site adjacent to the heel side of the ball of the big toe (f1a), a pressing portion (32) is formed for pressing the second site, so that the reaction force occurring by the pressing causes the first site to sink in the concave portion (31).
