Abstract: A shoe midsole is composed of a base plate (1), a cover (2), a plurality of blades (3), and liquid (4). The blades (3) are formed in such a manner as to rise within a first region (11) of the base plate (1). The blades (3) are each composed of a plurality of flat-shaped blade elements (32, 33) separated each other by slits (31), and are tilted toward the toe side or the heel side. The flat-shaped blade elements (32, 33) are disposed in such a manner as to be divergent toward the toe side or the heel side. The base plate (1) and the cover (2) are joined together, thereby forming a closed space (5), and the liquid (4) is sealed in the closed space.

Abstract: A shoe midsole has a sole plate, a plurality of blades integrally standing on the sole plate, a cover bonded to the circumference of the sole plate, and a fluid sealed between the sole plate and the cover. A first concave part in a shape equivalent to a sole of a foot is formed on the surface of the sole plate, on which the plurality of blades stand, wherein the plurality of blades are accommodated within the first concave part. The plurality of blades are aligned at a predetermined interval in a direction nearly orthogonal to the longitudinal direction of the sole plate, and some of the plurality of blades are tilted toward the toe.
