The invention describes a buffer (2) for a stick (1), in particular for a walking stick or a trekking or Nordic-Walking pole. The buffer (2) has means (10) for being attached to a stick tube (Ia), in particular in the form of a recess, at its upper end (4) and a rolling surface (5) at its lower end. In this case, the rolling surface (5) is of substantially flat or only slightly convex design in atransverse direction (22) in relation to the rolling motion but in a longitudinal direction (21) which is perpendicular thereto is convexly curved in such a way that it forms a rolling surface on a base surface (3) during the pushing-off movement with the stick when the user of the stick (1) moves. In the case of a buffer (2) of this type, an excellent degree of suitability and adhesive action for a very wide variety of base surfaces and at the same time quiet and problem-free use on hard base surfaces can be achieved by the buffer (2) being formed from an elastomeric material at least in theregion of the rolling surface (5), and by at least one elastically mounted, hard, inelastic retaining element (9) being arranged in the elastomeric material.
