点があった。Shoe soles equipped with such shock-absorbing materials exhibit relatively excellent 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 part corresponding to the lower protrusion of the calcaneus at the initial stage of landing, so the landing impact pressure is transferred to the heel. It cannot be absorbed sufficiently in areas corresponding to the protrusions below the bone, and furthermore, 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.

の靴底を発明の要旨とするものである。(Means for Solving the Problems) The present invention will be described below with reference to the drawings. A soft transparent elastic body 1 provided with a large number of compression holes 14, 14, etc. in the vertical direction is embedded in the heel portion of the sole 2. At the same time, the transparent elastic body 1

- The gist of the invention is a shock-absorbing shoe sole that is characterized by being transparent through the sole.

によって構成されている。In this invention, the transparent elastic body 1 includes vinyl chloride resin, vinyl chloride ethylene copolymer resin, vinyl chloride vinyl acetate copolymer resin, ethylene vinyl acetate copolymer resin, 1.
It is composed of 2-polybutadiene resin, polyurethane, transparent compound rubber, etc.

より好ましくは３０°〜５０″′のものが始套セ…。As for the hardness, the hardness according to JIS K6301 Spring Type Hardness Test Type A is 20° to 70'' (IF), preferably 30° to 50''.
硬さがそれ以下となれば圧縮変形性による衝撃吸収性は
良くなるが回復力が劣り永久歪が大きくなり耐久性が低
下する。また硬さがそれ以上となれば、圧縮変形性が低
下し同時に衝撃吸収性が低下するきらいがある。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.

ロネーシ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. If... is formed to the same size as a whole,
If the compression holes 14, 14, .・A compression hole 14", 14 arranged on the inner side 12 of the
"...", and its outer side 11 is located on the outer heel side 23 of the sole 2, and its inner side 12 is located on the inner side 22 of the heel of the sole 2. If embedded in the heel of the shoe sole, the maximum impact pressure at the initial stage of landing that is applied to the heel outer side 23 of the sole 2 during normal walking and running will be applied to the outer side 11 of the transparent elastic body. Formed compression holes 14.14...
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 sole 2, the inner side 12 of the transparent elastic body 1 is effectively absorbed by the layer. The compression holes 14.14... formed in the outer side 11 have a smaller surface area occupation rate than the compression holes 14.14... formed in the outer side 11. This is advantageous because the compressive deformation rate is suppressed, and the medial side 22 of the heel portion of the sole 2 is not excessively adducted, and overpronation is prevented.

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