Shoe sole and shoe

A shoe sole comprising:

• a shock absorber;
• a midsole;
• and
• a tread,
• the shock absorber including a shock absorbing portion, the shock absorbing portion comprising a three-dimensional structure composed of a plurality of unit structures repeatedly, regularly and successively disposed in at least one direction, each unit structure having a three-dimensional shape configured by a wall having an external shape defined by a pair of parallel planes or curved surfaces,
• the shock absorbing portion having a plurality of pass-through portions passing through the shock absorbing portion as viewed in a direction normal to the tread,
• the shock absorber, as viewed in the direction normal to the tread, having a cover portion that corresponds to at least one of the plurality of pass-through portions included in the shock absorbing portion and covers that pass-through portion,
• the shock absorber being configured of a single member configured with the shock absorbing portion and the cover portion continuously connected together,
• the tread being defined by a main surface of the cover portion that is located on a side opposite to a side where the shock absorbing portion is located,
• the cover portion defining a communication path having one end open to the at least one covered pass-through portion and the other end open at the tread,
• the shoe sole satisfying a condition of R<L, where R represents a diameter of a largest virtual incircle of a contour line of an opening of the communication path located closer to the tread, and L represents a length of the communication path in a direction in which the communication path extends,
• the midsole having a notch in a lower portion thereof for accommodating the shock absorber between the midsole and the tread, and the shock absorber is bonded to the midsole such that an entirety of a top surface of the shock absorbing portion is covered by the midsole, including a topmost portion of each of the plurality of pass-through portions.
