Definitions

  • the present invention relates to a buffer for a stick, in particular for a trekking, walking or Nordic walking pole, wherein the buffer at its upper end means for attachment to a pole tube, in particular in the form of a recess, and at its lower end a Rolling surface, wherein the rolling surface in a transverse direction with respect to the rolling substantially flat or only slightly convex curved, but in a longitudinal direction perpendicular thereto is convex so convex that during the movement of the user of the stick a rolling surface during the repulsion movement with the stick on a base.
