Shoe soles equipped with such shock-absorbing materials exhibit relatively good shock absorption and landing stability during light running such as normal walking or jogging, but they are also used in tennis, basketball, soccer, and long-distance running. When the landing impact pressure is large, such as when jumping, a load of more than three times the body weight pressure is concentrated on the lower part of the calcaneus corresponding to the protrusion at the beginning of landing, so the landing impact pressure is applied to the heel. It cannot be absorbed sufficiently in areas corresponding to the lower protrusions of bones, and in addition, such low-resilience foams have a large compression set, and have the disadvantage of being compressed and deformed with long-term use, resulting in a lack of durability.

In this invention, the transparent elastic body 1 is made of vinyl chloride resin, vinyl chloride ethylene copolymer resin, vinyl chloride vinyl acetate copolymer resin, ethylene vinyl acetate copolymer resin, 1.2 polybutadiene resin, polyurethane, transparent compound rubber, etc. It is structured as follows. As for the hardness, those having a hardness of 20° to 60°, particularly preferably 30° to 50°, according to JIS 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. Moreover, if the hardness is higher than that, the compressive deformability tends to decrease and at the same time, the shock absorbability tends to decrease.

In this invention, the compression holes 14, 14 are formed in the outer side 11 of the transparent elastic body and the inner side 12 thereof.
Specifically, when the compression holes 14, 14... are formed to have the same size overall, they are arranged concentrated on the outer side 11 so that the surface area occupation rate is larger than that of the compression holes 14, 14... In addition, when the compression holes 14, 14... are arranged uniformly throughout, the outer side 1
The compression holes 14', 14'... arranged on the sole 1 are formed larger than the compression holes 14'', 14''... arranged on the inner side 12, and the outer side 11 is formed at the heel of the sole 2. If the inner side 12 is located at the inner side 22 of the heel of the sole 2 and embedded in the heel of the shoe sole, the sole 2 can be easily removed during normal walking and running. The maximum impact pressure at the initial stage of landing, which is applied to the outer side 23 of the heel of the shoe, is absorbed more effectively by the compression holes 14, 14 formed in the outer side 11 of the transparent elastic body, and the sole 2 When the heel inner side 22 of the sole 2 lands on the ground following the landing of the heel outer side 23 of the shoe, the compression holes 14 formed in the inner side 12 of the transparent elastic body 1 close to the outside Since the surface area occupation rate is smaller than that of the compression holes 14, 14 formed in the side part 11, the compression deformation rate is suppressed in the inner side part 12 than in the outer side part 11, and the sole of the shoe This is advantageous because overpronation is prevented without the medial side 22 of the heel 2 being excessively internally rotated.

In this invention, if the compression holes 14, 14... are narrowed at their central portions 141, 141... and the cross-sectional shape in the vertical direction is formed into a zigzag shape,
As shown by the arrow in FIG. 2, the landing shock is absorbed from the radial direction of the lower surface, and the landing shock 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 impact cushioning property is improved, and the elastic recovery power is also improved, making it possible to make the wearer's comfort even better.

In this invention, a transparent synthetic resin film 2
11, 211 may be stretched on the inside of the windows 21, 21, or may be stretched on the outside of the windows 21, 21 (effects of the invention) Since this invention is configured as described above, ,
When walking or running while wearing the shoes, the landing impact pressure applied to the heel of the sole 2 is absorbed by the compression of the compression holes 14, 14 formed in the transparent elastic body 1. The body 1 has a smaller compression set than conventional low-resilience foams, and the compression set does not change even after long-term use, so it has good durability.

In addition, compression holes 14, 1 formed in the transparent elastic body 1
4... The compression deformation when worn is observed through the transparent windows 21 and 2.
Since it can be seen through from 1, it is possible to visually emphasize the impact absorption effect. In addition, the transparent elastic body 1 has compression holes 1
Since the weight is reduced by 4, 14, etc., there is no increase in weight compared to conventional low-resilience foams. Furthermore, the windows 21, 21 are covered with a transparent synthetic resin film 2.
11 and 211 are installed, so windows 21 and 21
It is hygienic because water or dust does not enter the shoes.
