A midsole unit ( 1 ) for a shoe ( 100 ) including a midsole ( 2 ) having a top layer ( 3 ) and base layer ( 4 ), wherein the midsole ( 2 ) defines a plurality of base layer grooves ( 5 a - 5 c ) extending at the base layer ( 4 ) of the midsole ( 2 ), wherein the midsole ( 2 ) includes a plurality of block elements ( 6 d , 6 e ) which are defined and separated from each other by the plurality of base layer grooves ( 5 a - 5 c ), wherein the midsole ( 2 ) further defines a plurality of top layer grooves ( 7 a - 7 c ) extending at the top layer ( 3 ) of the midsole ( 2 ). The midsole unit further includes a rigidifying structure.

Disclosed herein is a sole plate unit ( 1 ) for a running shoe sole being configured for storing and releasing energy during running, wherein the sole plate unit ( 1 ) comprises a sole plate ( 2 ), wherein the sole plate ( 2 ) comprises a base layer ( 22 ) and a top layer ( 21 ), wherein the base layer ( 22 ) and the top layer ( 21 ) are configured such that they define a compartment with a compartment volume; a polymer foam element ( 3 ) being arranged within the compartment defined by the base layer ( 22 ) and the top layer ( 21 ).

A method for manufacturing a foamed polymer product having a series of openings and a compression mold including a series of pins for use in the method. The method includes the steps of providing a foamed polymer preform having a certain height, width and length and comprising a series of openings extending into or through the preform; inserting the preform into the compression mold by sliding the preform with the series of openings onto the corresponding series of pins of the compression mold; and shaping of the preform in the compression mold to form the product having a compressed height, width and/or length by compressing the preform inside the compression mold, in particular by pressing the top and the base towards each other and by heating of the preform inside the compression mold.

A sole for a running shoe comprising a sole tip, a heel edge and a midsole having a base surface delimiting the midsole against the vertical direction (V) and a top surface delimiting the midsole in the vertical direction, wherein the midsole has a heel region (FB), a midfoot region (MFB) and a forefoot region (VFB) and an elastic plate. The elastic plate extends at least from the forefoot region into the midfoot region, and in the forefoot region and/or in the midfoot region has a first curvature with a vertex curved along the longitudinal direction (L) of the midsole in the direction of the top surface of the midsole. The elastic plate is formed so the first curvature is elastically bent in the direction of the base surface by the forces acting during treading and/or rolling movement, and the first curvature returns to its original shape during push-off, or wherein the elastic plate in the forefoot region and/or in the midfoot region has a first curvature curved along the longitudinal direction of the midsole in the direction of the base surface of the midsole and having a vertex. The elastic plate is configured such that the first curvature is elastically bent in the direction of the top surface by the forces acting during treading and/or during rolling movement, and the first curvature returns to its original shape during push-off.

A sole for a running shoe with a soft-elastic midsole ( 1 ) includes an underside ( 2 ) at least partially contacting the ground (B) during running and comprises a plurality of channels ( 3 a, 3 b, 3 c, 3 d, 3 e, 4 a, 4 b, 4 c ) extending in the transverse direction (Q). The channels ( 3 a, 3 b, 3 c , 3 d, 3 e, 4 a, 4 b, 4 c ) are arranged in a lateral area of the midsole ( 1 ) in at least a first and a second in horizontal plane, wherein the first and second horizontal plane are vertically offset from each other, and wherein the channels ( 3 a, 3 b, 3 c, 3 d, 3 e, 4 a, 4 b, 4 c ) are each delimited in longitudinal direction (L) by a front wall and a rear wall. The channels ( 3 a, 3 b, 3 c, 3 d, 3 e, 4 a, 4 b, 4 c ) are vertically and/or horizontally in the longitudinal direction (L) deformable until their closure under the action of forces occurring during running acting vertically (V) and/or longitudinally.
