Abstract:
1. A sole for a shoe designed to increase an instability upon striking the ground, the sole extending from a rear heel region via a metatarsal region to a front forefoot region, wherein, in a region of a gait line, the sole comprises: an instability region which follows a contour of the gait line and extends along the gait line along an entire length of the sole in a longitudinal direction of the sole so as to reduce a stability of the shoe when the shoe strikes the ground in a normal gait; and at least one of: a bulk modulus which is increased compared to a medial outer region and a lateral outer region of the sole adjacent to the instability region, and a sole thickness which is increased compared to the medial outer region and the lateral outer region of the sole adjacent to the instability region so as to provide an uneven sole contour perpendicular to a running direction.
