Vibration absorption system, to be inserted in poles for Nordic walking, hiking and the like, of the type in which the vibration absorption system, placed between two axial tubular elements which constitute the telescopic rod of the pole, namely a tubular element (1 ) fixed to the grip and a tubular element (2), fixed to the part which touches the ground, is provided with an elastic element (3), coaxially inserted and placed so that, in the thrust step, the tubular element (1 ) slides inside the tubular element (2). Said vibration absorption system (100) is characterized by the fact that the elastic element (3) is made of a material which belongs to the family of the polyurethane foams (Fig. 1 ). |
