  • the present inventor has found that in a shoe sole made of a rubber composition, the above-mentioned problem can be solved by including particles having holes that are difficult for water to enter in the shoe sole. Then, the present inventor has found that activated carbon is suitable as such particles.
  • Activated carbon is highly hydrophobic and the size of the holes opened on the surface is about 1 ⁇ m, so it is difficult for water to enter the holes even if it comes into contact with water.
  • the present inventor puts activated carbon with fine pores, which was thought to be unsuitable for the purpose of absorbing water, on the sole, and when the sole comes into contact with the ground through a film of water, the sole is distorted.
