A sole assembly includes a medial part, a lateral part, and a central axis extending from a heel region towards a forefoot region of the sole assembly. A first sole part (midsole or outsole) has a ground facing surface and a foot facing surface. A medial reinforcement member is positioned at a medial side of the sole assembly, and/or a lateral reinforcement member is positioned at a lateral side of the sole assembly. The medial reinforcement member and/or the lateral reinforcement member include a transverse part extending in a transverse direction from a peripheral boundary of the first sole part in a direction towards the central axis.
