• the individual damping parts for arrangement in the recesses are selected such that the shoe or its sole has a desired spring and damping behavior and / or a desired pronation or supination behavior.
• the invention therefore aims to design the damping element in the form of a plate and to provide it with a number of damping parts, the material properties of which are selected such that the spring and damping properties of the shoe sole as a whole can also be actively influenced with regard to the spring stiffness about the longitudinal axis of the shoe.
• the spring stiffness around the longitudinal axis of the shoe By influencing the spring stiffness around the longitudinal axis of the shoe, the pronation or supination behavior of the sole can be specifically influenced and adapted to individual needs.
• a further development provides that the receiving space is arranged in the sole in the heel area.

• the plastic material is foamed according to a training.
• the material of the base body and or of the damping parts preferably has a greater hardness than the material of the sole.
• the plastic of the base body or the damping parts can have a Shore hardness between 25A and 45A.
• the plastic of the base body has a lower hardness than that of the damping parts.
• the material of the sole is translucent or transparent in the area of the base body and / or the damping parts.
• a holding element can also be provided, which fixes the base body in the position arranged in the receiving space.
• the holding element can be designed in the shape of a bow and encompass the sole from below. Both the sole and the base body can have recesses for positive interaction with the holding element.
• the sole can consist of a midsole and an outsole connected to it, and the damping element can be arranged in the midsole.
• the shoe according to the invention can have a system consisting of several damping parts of different hardness, which can be exchanged and arranged in the recesses of the base body.
• Each hardness level of the damping part is advantageously assigned a defined color with which the damping parts are colored, at least on their outer surface. This means that the desired damping parts can be selected quickly and easily in order to adapt the shoe to individual needs.
• FIG. 1 is a perspective view of a sports shoe with the damping element removed
• Fig. 2 shows the damping element according to section A-B (see Fig. 1) and
• Fig. 3 shows the rear part of the sports shoe shown in perspective with inserted damping element and attached holding element with a view of the shoe from below.
• a sports shoe 1 is outlined. This has a sole 2, which is connected to a shoe upper 3 in the usual way.
• the sole 2 is sketched in one piece. However, it usually consists of several sub-elements, e.g. B. from a midsole, on the underside of which an abrasion-resistant outsole is arranged.
• the sole 2 is provided with a damping element 5 in order to be able to adjust the spring and damping behavior of the shoe 1 to individual needs.
• the damping element 5 is introduced into a receiving space 4, that is to say inserted, which extends over a certain extent along the longitudinal axis L of the shoe 1 and extends through the sole 2 transversely to this direction.
• the receiving space 4 completely penetrates the sole 2, so that there is a space extending from the left to the right side of the sole.
• the extension of the The receiving space 4 along the longitudinal axis L of the shoe 1 is selected such that the damping element 5 lies between the midfoot and the heel area.
• the damping element 5 consists of a plate-shaped base body 6 which has a number of recesses 7. These extend over the entire height H of the base body 6 or damping element 5, as can be seen in FIG. 2. Damping parts 8 are inserted into the recesses 7. These damping parts 8 consist of plastic material with the desired hardness and rigidity.

It can thus be achieved that not only the spring and damping properties of the sole 2 are adjusted to the individual wishes, but also the pronation and supination behavior of the sole 2 is adjusted. For example, in a lateral area of the base body 6, harder damping parts 8 used than in the other lateral area, there is a preferred deflection on the sole side with the lower hardness or elasticity, which has a direct effect on the pronation or supination property of the sole 2.
