A sole structure of a sports shoe comprises an outsole (11) and a midsole (10) consisting of a number of portions, which midsole (10) is flexible and supports the foot during running. The midsole (10) comprises a flexible body element (12) extending along the entire length of the shoe, and a flexible heel absorption element (13) extending to the heel area, and a support element (14) which is sandwiched between the body element (12) and the heel absorption element (13) and extends from the heel area to the ball area and which is of a less flexible material than the body element (12) or the heel absorption element (13). The support element (14) comprises a substantially plate-like heel portion (17) and a shaped front portion (18), which are separated from each other by a substantially cross-directional support ridge (19) protruding from the lower surface of the support element (14). The midsole (10) also includes an hourglass-shaped ball absorption element (16), a carbon fibre plate (21) increasing the torsional rigidity
