A shoe sole, a shoe and a method for producing a shoe sole, which has at least one cleat that is designed to make contact with the ground on the underside of the sole facing towards the ground when used as intended. In order to improve the traction of the shoe fitted with such a shoe sole the cleat has a base body that is fixed to the underside of the sole, wherein an arcuate recess having a longitudinal direction of arc is arranged in the base body which has two openings on a surface facing the ground of the base body. An insert having a shape congruent to the arcuate recess is arranged in the recess. The insert is arranged such as to be movable in the base body in the longitudinal direction of arc of the arcuate recess.

Shoe sole, shoe with such a shoe sole and method for the production of such a shoe sole

The invention relates to a shoe, particularly to a sports shoe, with a sole (), wherein the sole () comprises at least one spring element (), which spring element increases the bending stiffness of the sole () around an axis (Q) which is oriented horizontally and perpendicular to a longitudinal direction (L) of the sole (). To create a shoe which sole has a sufficient bending stiffness and spring properties respectively without employing separate measures, i. e. without employing a spring element, the invention proposes that the sole comprises at least one receiving groove () for the at least one spring element (), in which the spring element () is arranged in such a manner that it can slide at least along a part of its extension in longitudinal direction (L) relatively to the sole ().

Shoe, particularly sports shoe

A damping element for a shoe, especially for a sports shoe, having at least one first element which extends essentially in a load direction over a pre-determined height in the unloaded state of the damping element, and is embodied as a hollow body defining a receiving area in which an associated second element with a smaller cross-section can at least partially penetrate. The second element extends essentially in the load direction over a pre-determined height in the unloaded state of the damping element, and is arranged coaxially in relation to the first element. To improve the damping performance of the shoe, the second element is also embodied as a hollow body and the two associated elements are interconnected by means of an elastic connecting section which only extends between the first-element and the second element so that the elements together form a gas-tight chamber.

Damping element for a shoe

The invention relates to a turn-lock fastener ( ) for detachably adjusting and varying the effective length of at least one tensioning element ( ) with a winding device which can be Actuated at least in a closing direction via a turning grip ( ) that can be actuated around a central axis ( ). The invenitve turn-lock fastener should be designed in such a way that it can be easily inserted into a base plate ( ) and can be easily removed therefrom. To this end, the turn-lock fastener ( ) and the base plate ( ) are interconnected in an articulated manner via a turning joint ( ) in such a way that the turn-lock fastener ( ) can be pivotally folded down like a flap to the base plate ( ) and can thereby locked with the same or the turn-lock fastener can be foleded away from the base plate and can thereby be unlocked from the same.
