柱状であつてもよい。1 (a) to 1 (c) show an example of the shoe sole of the present invention, in which reference numeral 11 is a sole cover. The bottom surface of the bottom covered portion 11 is provided with a large number of elastic projections 12 ... This elastic projection 12 is shown in FIG.
As shown in (b), a cylindrical base end portion 13 projects from the bottom cover portion 11, and a hemispherical grounding portion 14 is continuously and integrally formed on the base end portion 13. The outer surface of the portion 14 serves as the ground contact surface 15. And this elastic protrusion 1
The groove 16 is formed in the groove 2. This groove 16 is shown in FIG.
As shown in (c), the plane shape is substantially cross-shaped, and the groove 16 divides the ground plane 15 into four. Also, groove 1
In this example, the depth of 6 is set so as to reach near the bottom surface of the bottom covered portion 11. The base end portion 13 may have a tapered cylindrical shape.
このような弾性突起１２は、第１図(a)のように底被部

さらに適当な模様、柄が現出するように配置してもよ
い。Such an elastic protrusion 12 may be provided on the entire surface of the bottom covered portion 11 as shown in FIG. 1 (a), or it may be locally provided in consideration of a portion having a high ground contact frequency such as a heel portion or a tread portion. It may be provided or the distribution density may be changed. Also,
The elastic projections 12 may be arranged regularly as shown in FIG. 1 (a), or may be arranged irregularly and irregularly.
Further, they may be arranged so that an appropriate pattern or pattern appears.
また、弾性突起１２の材質は、底被部１１の材質と同一
でも、異つていてもよく、底被部１１よりも耐摩耗性、
摩耗特性、衝撃吸収性にすぐれる材料を用いることによ
つて、弾性突起１２の耐摩耗性、防滑性、緩衝機能を向
上させることができ、靴底の耐久性を高めることができ

切り性、排水性が優れているため、濡れた地面での防滑
性が極めて高いものとなる。In the case of a shoe sole provided with such elastic protrusions 12, ... Since the groove 16 is formed, each divided portion of the elastic protrusion 12 is rich in vertical and lateral elasticity, and the shock absorbing function is enhanced. Along with that, the anti-slip function is also greatly improved. In particular, since the ground is gripped with a slight stepping pressure and the drainage and drainage are excellent, the slip resistance on the wet ground is extremely high.
また、溝１６を放射状に形成したため、異方性が少く、
靴底としての機能設計を容易にするとともに踏みつけた
場合の弾性突起１２自身のつけ上げ感が減少する。Moreover, since the grooves 16 are formed radially, the anisotropy is small,
The functional design as the shoe sole is facilitated and the feeling of the elastic protrusion 12 itself being raised when stepped on is reduced.
さらに、弾性突起１２は、微かの踏つけ圧で地面を上述

わつた際には、分割された各部分の協働作用により、過
度の変形を防ぎ、これにより耐摩耗性が優れる。Further, the elastic projection 12 surely grips the ground with a slight treading pressure as described above, but when a large treading pressure is applied, the elastic projections 12 are excessively deformed by the cooperation of the divided parts. Which results in excellent wear resistance.
またさらに、弾性突起１２は、斜めからの外力を受けた
場合でも、その部分の変形が溝１６によつて容易とな
