Sole with variable damping properties

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. The acute angle formed between the main longitudinal axis and the base surface of at least one channel arranged in the heel region is greater than the acute angle formed between the base surface and the main longitudinal axis of at least one channel arranged in the central foot region and/or in the front foot region.
