A shoe sole (7) consisting of a midsole (1) and an outsole (3) consisting of discrete outsole elements. The midsole (1) has on the side facing the outsole a multiple of flex grooves (27, 29, 34, 51, 53, 55, 57, 63) crossing each other and creating pads (26, 28, 30, 33, 35, 50, 52, 54, 56) in the midsole. A curved forefoot flex groove (63) emanates from the medial side (21) of the arch (48) and essentially follows a path over one or more of the cuneiform bones (72, 73, 74) and continues between the third (83) and fourth (82) metatarsal phalanges, over the third (77) proximal phalange and continues between the first (85) and second (84) metatarsal phalanges in a direction towards the heel. Both the outsole elements and the pads are arranged to follow an essentially spiral curve (64) around the curved forefoot flex groove. The sole reduces the risk of injury during running, and gives the foot increased compensation possibilities for correcting imbalances especially after heel strike.
