性板間に低反発弾性発泡体を介在接着させた衝撃吸収材
を、靴底の踵部に積層した運動靴を提案した。(Prior Art) The applicant previously proposed, in Japanese Patent Application No. 59-135818, an athletic shoe in which a shock absorbing material in which a low-resilience foam was interposed and bonded between rigid plates was laminated on the heel of the shoe sole. did.

点があった。Shoe soles equipped with such shock absorbers exhibit relatively good shock absorption and landing stability during light running such as normal walking or jogging; When the landing impact pressure is large, such as when running or jumping, a load of more than three times the body weight pressure is concentrated on the area corresponding to the lower protrusion of the calcaneus at the initial stage of landing, so the landing impact pressure must be reduced. The area corresponding to the lower protrusion of the calcaneus could not be absorbed sufficiently, and this kind of low-resilience foam had a large compression set, which caused it to compress and deform with long-term use, resulting in a lack of durability. .

It is composed of 2-polybutadiene resin, polyurethane, transparent compound rubber, etc. And its hardness is J
Those having a hardness of 20° to 60°, particularly preferably 30 to 50° according to IS K6301 spring type hardness test type A are used. If the hardness is less than that, the shock absorption property due to compressive deformability will be improved, but the recovery power will be poor, the permanent set will be large, and the durability will be reduced. If the hardness is higher than that, the compressive deformability and shock absorption properties tend to decrease at the same time.6 The transparent elastic body 1 may have a circular, oval, or
A large number of polygonal compression holes 14, 14... are provided in the vertical direction.

ョンが防止されることになり好都合である。In this invention, the compression holes 14.14 are arranged so that the surface area occupancy is larger on the outer side 11 of the transparent elastic body than on the inner side 12.
4... are formed to have the same size as a whole, the compression holes 1 are arranged concentrated on the outer side 11, and the compression holes 1
4. When 14... are arranged uniformly throughout, the compression holes 14', 14'... arranged on the outer side 11 are replaced with the compression holes 14'', 14''... arranged on the inner side 12. The outer side 11 is located on the outer heel side 23 of the sole 2, and the inner side 12 is located on the inner side 22 of the heel of the sole 2. By embedding it in the heel of the transparent elastic body, the maximum impact pressure applied to the outer side 23 of the heel of the sole 2 during normal walking and running at the initial stage of landing will be reduced by the pressure formed on the outer side 11 of the transparent elastic body. The transparent elastic body 1 is effectively absorbed by the compression holes 14, 14 when the inner heel side 22 of the sole 2 lands on the ground following the landing of the outer heel side 23 of the sole 2. Compression holes 14 formed in the inner side 12 of
．． 1.4... is the compression hole 1 formed in the outer side part 11
4.14 Since the surface area occupation rate is smaller than that of..., the compressive deformation rate is suppressed on the inner side 12 than on the outer side 11, so that the inner side 22 of the heel of the sole 2 This is advantageous because overpronation is prevented without being excessively adducted.
になり好都合である。This is convenient.

とすることができる。As shown by the arrow in Fig. 2, the landing impact is absorbed from the radial direction of the lower surface, and the landing impact that cannot be absorbed by the compression holes 14, 14... is dispersed along the wall surface 140 in the radial direction of the upper surface. As a result, the shock mitigation properties are also good,
Furthermore, the elastic recovery force is also improved, making it possible to make the wearer's comfort even better.

211 may be attached to the inside of the window 21.21 or may be attached to the outside of the window 21.21 (effects of the invention). When walking or running, the landing impact pressure applied to the heel of the sole 2 is absorbed by compression holes 14 and 14 formed in the transparent elastic body 1.
..., and the transparent elastic body 1 has a smaller compression set than conventional low-resilience foams, and the compression set does not deform even after long-term use, so it has good durability. .

ある。Furthermore, since the compression deformation of the compression holes 14, 14, etc. formed in the transparent elastic body 1 during wear can be seen through the see-through windows 21, 21, the impact absorption effect can be visually emphasized. Furthermore, since the transparent elastic body 1 is lightened by the compression holes 14, 14, it does not increase in weight compared to conventional low resilience foams. Furthermore, since the window 21.21 is covered with a transparent synthetic resin film 211.211, the window 21.21
It is hygienic because water or dust does not enter the shoes.
