A sole for a shoe, in particular a sports shoe, includes a unidirectional bending element. The unidirectional bending element enables a dorsal bending of the sole (bending of the sole in the direction upward and away from the ground) and blocks a plantar bending of the sole (bending of the sole in the direction downward and towards the ground). The unidirectional bending element may be arranged at a first layer of the sole and may vertically project from the first layer.
