配設様式に於ては、設定し得る衝撃吸収能力に限
界が有る。(Prior art) It has been known that a polyurethane viscoelastic material is contained or sandwiched in one or more locations of the sole of a shoe, thereby protecting the foot from vigorous exercise or strong impact under certain circumstances. ing. However, conventionally, such a polyurethane viscoelastic body 5 (see FIG. 1) is generally arranged in a flat shape, for example, on the lower surface of the inner sole of a shoe. However, while this maintains the external flatness of the inner sole of the shoe, it limits the thickness of the polyurethane viscoelastic body, which determines its shock absorption ability. Therefore, in the conventional manner of disposing the viscoelastic body on the sole of the shoe, there is a limit to the shock absorption capacity that can be set.
（考案の目的）
従つて本考案の目的は、くつ底に配設された粘
弾性体の対衝撃吸収能力の限界を引上げることで
ある。(Purpose of the invention) Therefore, the purpose of the invention is to raise the limit of the shock absorption ability of the viscoelastic body disposed in the sole of the shoe.

られたよりも一層高められる。(Summary of the invention and its effects) According to the invention, in the inner sole of a shoe in which a polyurethane viscoelastic material for impact absorption is arranged in the midfoot and/or heel part, the polyurethane viscoelastic material is disposed downwardly. The polyurethane viscoelastic material has a curved protruding shape, thereby increasing the impact absorption ability of the polyurethane viscoelastic body more than previously obtained.

Shore 00 hardness to 30 obtained by reacting 1 equivalent of a mixture consisting of a polyol of 100% and a polyol with a molecular weight of 60 to 700 with 0.7 to 1 equivalent of an organic polyisocyanate in the presence of inert liquid and solid diluents. 70, consisting of super energy-absorbing polyurethane elastomer with rebound resilience from 0.5 to 40%. The polyurethane viscoelastic body is the inner sole 10 of the shoe.
It is arranged as shown in the midfoot part 14 and/or the heel part 16, and its cross section curves downward as shown in FIG. 3, that is, with respect to the midsole (see FIGS. 4 and 5). Shape.

れることになり、衝撃吸収性が改善される。 Please refer to FIG. A central flat recess 20 that can engage with the polyurethane viscoelastic body 12 is provided in the midsole 18 at a position opposite to the position where the polyurethane viscoelastic body 12 is provided.
The depth of the recess 20 is preferably smaller than the protrusion dimension of the polyurethane viscoelastic body 10. Therefore, during shoe manufacturing, the shoe inner sole 10 and the shoe inner sole 1 are
8 are joined, the curved protrusion of the polyurethane viscoelastic body is connected to the recess 2 of the shoe midsole 18.
An upward stress is applied by the flat portion of the shoe, thereby causing a portion of the surface of the insole 10 to bulge upward (see FIG. 5). As a result, the polyurethane viscoelastic material is disposed inside the shoe at a thickness that cannot be achieved using the conventional method of attaching the polyurethane viscoelastic material in a flat shape. , shock absorption is improved.

題を生ずることが無い。 In addition, the polyurethane viscoelastic body in the curved protruding shape according to the present invention is pressed and deformed by the sole of the foot and takes about 1 second to restore its original shape. The shape of the polyurethane viscoelastic body does not cause any practical problems.
