A shoe comprising a sole having a supporting surface for supporting a foot and an upper connected with the sole for locking a foot onto the supporting surface. The sole comprises an elongate torsion stiffener for enhancing resistance to torsion about the longitudinal axis of the sole. The torsion stiffener extends in outward direction diagonally across the sole, such that as the sole is made to roll along the longitudinal axis by the foot, the resistance to outward torsion increases. The invention also relates to a sole.
