Running shoe sole comprising a soft-elastic midsole

A sole for a running shoe having a soft-elastic midsole (1) which has an underside (2) which comes at least partially into contact with the ground (B) during running, the midsole (1) comprising:

• a plurality of channels (3a, 3b, 3c, 3d, 3e, 4a, 4b, 4c) extending in a transverse direction (Q), the channels (3a, 3b, 3c, 3d, 3e, 4a, 4b, 4c) being arranged in a lateral area of the midsole (1) in at least a first and a second horizontal plane, wherein the first and second horizontal plane are vertically offset from one another, and wherein the channels (3a, 3b, 3c, 3d, 3e, 4a, 4b, 4c) are each delimited in a longitudinal direction (L) by a front wall (31) and a rear wall (32) and wherein the channels (3a, 3b, 3c, 3d, 3e, 4a, 4b, 4c) 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 in the longitudinal direction.
