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.

Shoe midsole and footwear

A recess portion and a thick outer peripheral portion are formed in an upper surface of a bottom plate . A recess portion is formed in a lower surface of a cover . The recess portions and have configurations corresponding to a combination of a tarsal portion of a foot covering an area from a heel to substantially a center portion of a foot and a metatarsal portion of the foot covering an area from the center portion to roots of toes of the foot, respectively. A plurality of blades are integrally formed on a surface of the recess portion , extend in directions perpendicular to a longitudinal direction of the bottom plate and are slanted toward a heel portion of the bottom plate. The welded portions and of the upper surface of the bottom plate and the lower surface of the cover, which directly surround the respective recess portions and have uniform width, are welded together by a high frequency welder and fluid is sealed in a space defined by the recess portions and . Since the width of the welded portions and is uniform, the adhering strength becomes uniform, so that a water leakage can be prevented. Further, the insole or sole of shoe can massage a sole of foot while absorbing shock during walking, with reliable welding of the bottom plate and the cover.

Insole or sole of shoes and manufacturing method thereof

A bottom plate has its top surface formed with a recess with a plurality of slanted blades formed therein. A cover has a recess and an increased thickness portion formed around the recess and extending toward a marginal portion. A fluid is sealed in both the recesses. In the recess of the cover, fluid shock buffer blades are formed on at least a portion, which is urged by foot fingers and swelling foot finger roots, the blades being slanted in a direction perpendicular to the longitudinal direction of the cover. The marginal portion of the cover is fused to the marginal portion of the bottom plate.

Mid-sole or sole of shoes

A mid-sole or sole of shoes for massaging the sole of a foot by stimulating it during walking includes recess portions on the upper surface of a bottom plate defined by a wall portion, a plurality of blades in the recess portions extending in a direction perpendicular to the longitudinal direction of the bottom plate and being slanted in the same direction, a flexible cover sealed at the peripheral end portion of the upper surface of the bottom plate, and liquid injected and filled in the space provided between the bottom plate and the cover.
