Abstract: The kinematic shoe sole comprises a segmental structure, which is formed from a material layer comprising a lateral joint (1) and/or a medial joint, which divides the sole into the individual segments (3a). The lateral and/or the medial joint is partially or completely formed as a continuous groove by the material layer, where the groove is partially and/or completely filled with a flexible material. The lateral joint comprises a recess (4a), which is partially and completely filled with a material of equal size and/or lower shore hardness compared with the materials of the segments. The kinematic shoe sole comprises a segmental structure, which is formed from a material layer comprising a lateral joint (1) and/or a medial joint, which divides the sole into individual segments (3a). The lateral and/or the medial joint is partially or completely formed as a continuous groove by the material layer, where the groove is partially and/or completely filled with a flexible material. The lateral joint comprises a recess (4a), which is partially and completely filled with a material of equal size and/or lower shore hardness compared with the materials of the segments. The sole has three adjacent areas, a toe area in which the lateral joint passes parallel to the toes, a middle foot area in which the lateral joint has a non-linear shaped course and/or a tarsal area in which the no lateral and the medial joint are formed and the lateral joint passes parallel to the foot direction, where the lateral joint is continuously formed over the areas. The lateral joint is arranged in the toe area into the area of the two toes and/or in the middle foot area in direction from the toe area to the tarsal area, initially comprises the course parallel to a second middle foot bone, and then has a first bend (5a), where the lateral joint occupies the non course parallel to the middle foot bone in the direction of the other middle foot bone lying externally and then has a second bend (5b). The lateral joint occupies the directional course, which comprises itself into the toe area and/or passes into the tarsal area in the middle of the sole. The medial joint of the lateral joint branch off at the height of the first bend that passes in the direction of the first middle foot bone and/or the medial joint of the lateral joint branch off at the height of the second bend that passes the direction of the second middle foot bone and/or in the tarsal area at the height of the area forming the supporting point of the calcaneus, two medial joints of the lateral joint branch off, where the lateral joint passes to the inner- and/or outer side of the foot. The shoe sole has four recesses, which are circular. The lateral joint passes over four filled recesses, where the first filled recess is arranged in the toe area or at the height of the border between the toes- and the middle foot area, the second filled recess at the height of the first bend, the third filled recess at the height of the second bend, and/or the fourth recess in the tarsal area at the height of the supporting point of the calcaneus. The lateral joint and/or the medial joint is formed over the total length and/or width of the sole and/or over a part of the sole. All segments consist of the same materials, where the segments consist of the materials of different shore hardness and/or the material has the segment of a gradual course of the shore hardness. The shoe sole is formed itself as a segmental outsole, segmental midsole, and segmental insole or innersoles, and is formed in two layers and has the outsole and/or the insole or the innersoles arranged over the shoe sole, where the shoe sole is formed in multilayer and has the outsole of a midsole arranged over the shoe sole and/or the insole and/or the innersoles arranged over the shoe sole. One of the positions is formed as the shoe sole. Two positions are formed as the shoe sole, where each of the lateral joint, the medial joint and/or the filled recess are arranged in congruent or non-congruent manner, and has two layers in same or different length and/or width of the lateral and/or the medial joint or diameter of the filled recess. An independent claim is included for a shoe.
