Abstract: 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.

Abstract: A sole for a running shoe including an elastic midsole with a base surface, which delimits the midsole opposite the vertical direction of the midsole, and a surface, which delimits the midsole in the vertical direction. The midsole is divided into a heel region, a central foot region, and a front foot region, and includes multiple channels which run in the transversal direction of the midsole and are arranged one behind the other in the longitudinal direction of the midsole. Each of the channels has an elongated contour in the cross-section along a cross-sectional plane in the longitudinal direction of the midsole and perpendicularly to the transverse direction of the midsole, and each channel has a main longitudinal axis in the cross-section along the cross-sectional plane in the longitudinal direction and perpendicularly to the transversal direction.
