SOLE WITH VARIABLE DAMPING PROPERTIES

The invention relates to a sole for a running shoe, comprising an elastic midsole (1) with a base surface (2), which delimits the midsole (1) opposite the vertical direction (V) of the midsole, and a surface (3), which delimits the midsole (1) in the vertical direction (V). The midsole (1) is divided into a heel region (FB), a central foot region (MFB), and a front foot region (VFB), and the midsole (1) has multiple channels (41, 42, 43) which run in the transversal direction (Q) of the midsole (1) and are arranged one behind the other in the longitudinal direction (L) of the midsole (1). Each of the channels (41, 42, 43) has an elongated contour in the cross-section along a cross-sectional plane in the longitudinal direction (L) of the midsole (1) and perpendicularly to the transverse direction (Q) of the midsole, and each channel (41, 42, 43) has a main longitudinal axis (411, 421) in the cross-section along the cross-sectional plane in the longitudinal direction (L) and perpendicularly to the transversal direction (Q). The acute angle (α-41) formed between the main longitudinal axis (411) and the base surface (2) of at least one channel (41) arranged in the heel region is greater than the acute angle (α-42) formed between the base surface (2) and the main longitudinal axis (421) of at least one channel (42, 43) arranged in the central foot region (MFB) and/or in the front foot region (VFB).
