Abstract: A sole structure for a running shoe is presented having an outsole and a midsole. The sole structure includes a plurality of hollow elements, which are closed off in each case by front flanks and rear flanks, and have spaced-apart upper inner surfaces and lower inner surfaces, that forces to which the hollow elements are subjected when the runner is running are absorbed by these hollow elements in each case with deformation, with the spacing between their inner surfaces decreasing in the process. The upper inner surfaces of the hollow elements are formed on the underside of the midsole, that the lower inner surfaces of the hollow elements are formed on the upper side of the outsole, which is fastened on the underside of the midsole in each case in front of, and behind, the hollow elements, the front flanks and the rear flanks likewise forming part of the outsole.

Abstract: In a sole for a flexible shoe having a soft-elastic midsole which comes in contact with the ground at least partially during running, which has laterally open, trough-shaped elements which project downwards towards the ground and which are aligned transversely to the longitudinal direction thereof, a midsole is divided into a medial and a lateral part by a longitudinal slot extending from the heel into the ball region. The midsole can have an edge strip which bridges the trough-shaped elements in each case. The midsole is covered by an incompressible but elastically resilient plate framed by the edge strip and that the trough-shaped elements are deformable as far as closure of the lateral openings thereof in the region of the edge strip under the action of forces acting vertically and/or in the longitudinal direction which occur during running.

Abstract: In a sole construction for a running shoe having an outer sole and an intermediate sole, the sole construction including a plurality of hollow elements which are in each case closed off by front and rear flanks in the longitudinal direction of the sole construction but are open at the sides and have upper and lower inner faces at a mutual spacing. The hollow elements are configured to absorb forces which act on them during running in each case by elastic deformation with a reduction in the spacing between their inner faces and optionally by horizontal displacement of their inner faces with respect to one another. The hollow elements are configured to deform to such an extent that their upper and lower inner faces come into contact with one another, and that this contact prevents a horizontal displacement of their inner faces with respect to one another.
