Shoe, in Particular a Sports Shoe

Abstract

The invention relates to a shoe, in particular a sports shoe, comprising an upper part ( 1 ) and a sole ( 2 ). Said sole ( 2 ) comprises a support or inner part ( 2 ′) which is joined to the upper part ( 1 ), an intermediate sole ( 2 ″) which is joined to the support or upper part ( 2 ′) and an outer sole ( 2 ′″) which is joined to the intermediate sole ( 2 ″). According to the invention, the intermediate sole ( 2 ″) is embodied at least over one part of the base outlet surface as a damping element in order to maintain the simple production possibilities of the spring and dampening ratio of the shoe, said damping element comprising a plurality of first elements ( 3 ) which are arranged next to each other and which extend, essentially, in a load direction (R) over a pre-determined height (H) in the unloaded state of the damping element, and is embodied as a hollow body defining a receiving area ( 4 ) in which an associated second element ( 5 ) with a smaller cross-section then the first element ( 3 ) can at least partially penetrate. The second element ( 5 ) extends essentially in the load direction (R) over a pre-determined height (h) in the unloaded state of the damping element ( 1 ), and is arranged in a coaxial manner in relation to the first element ( 3 ).

1 . Shoe comprising a shoe upper part and a sole, where the sole has a support part or inner part connected to the shoe upper part a midsole connected to the support or inner part and an outsole connected to the midsole, wherein
 the midsole is, at least across a part of the ground-contact area of the shoe, exclusively a damping element, which has a number of first elements arranged alongside one another which in essence extend across a prescribed height (H) in a direction (R) of loading in the unloaded condition of the damping element and, being hollow bodies, define a receptacle into which an associated second element smaller in cross-sectional dimensions than the first element can penetrate at least to some extent,   wherein the second element in essence extends across a prescribed height (h) in a direction (R) of loading in the unloaded condition of the damping element and has been arranged coaxially with respect to the first element,   wherein the outsole is formed via a number of individual sole parts,   wherein each sole part has been arranged at that end of the second element that faces away from the first element or that end of the first element that faces away from the second element,   wherein the two elements associated with one another have connection to one another by way of an elastic connecting portion, which extends merely between the first element and the second element, and   wherein the second element is located in the unloaded condition of the damping element, viewed in the direction (R) of loading, outside the first element.
