Definitions

  • the present invention relates to a footwear outsole, with differentiated elasticity, particularly adapted for running and other sports.
  • the known solutions exclusively aim at providing an optimum support for the foot in the footwear.
  • the principal aim of the present invention is instead to perfect a footwear outsole with the particular purpose of improving the athletic performance, said outsole being able to soften the foot impact on the ground by dampening the traumatic pounding which reflects back from the limbs all over the body, which reduces tiring and which increases the pushing action by returning, upon detaching the foot from the ground, the energy accumulated by the compression at the landing.
  • a consequent primary object is to perfect an outsole adapted for providing an effective elastic reaction, while not compromising the safe bearing on the ground.
  • Another object is to perfect an outsole having an adhesion that is variable according to the changing of the load conditions.
  • Another object is to perfect an outsole obtainable at low costs with common equipment and installations.
  • an outsole with differentiated elasticity, particularly adapted for running and other sports, characterized in that it has, at a lower part, zones being particularly elastic and protruding downwards with respect to other more rigid zones so as to allow the latter to make contact with the ground during elastic compression of the former.
  • a footwear outsole according to the invention has a plan profile not differing from the known ones, while the vertical profile, both longitudinally and transversely, has a part 3 protruding downwardly with respect to the ground bearing surface of part 2, said sole being shaped so as to perimetrically frame said part 3.
  • the part 3 is covered below with a tread 3a which provides the necessary resistance in the ground contact zones.
  • both, the part 3 and sole 2 are filed to a plantar element or insole 1 and the former has a sufficient consistency to avoid that the foot perceives the different degree of elasticity of the latter, since, as mentioned before, the part 3 is considerably more elastic than the part 2 and therefore is intended to compress during the impact of the foot on the ground until also the sole 2 comes to bear thereon.
  • the part 3 advantageously yields back the energy accumulated from the elastic deformation.
  • an insole 4 less thick than the previous 1 for it is combined with a sole 5 which is not only limited to the framing of the elastic part 6, but extends over the entire plan surface of the outsole and accomodates in a recessed part thereof the aforesaid part 6 which, even in this case and for the above-mentioned reasons, protrudes downwardly with respect to the ground bearing surface of the sole 5.
  • the surface 6 is also provided with a tread 6a.
  • the outsole is obtained by fixing in recessed or depressed seats of a sole 7 provided with a plantar element or insole 4, similar to that of the preceding embodiment, two fillers 8 and 9 of a more elastic material, both extending from one side to the other of the aforesaid outsole.
  • treads 8a and 9a are suitably provided with treads 8a and 9a respectively.
  • a sole 10 is shown therein, for connection to the above cited plantar element or insole 4 which accomodates in adapted recessed seats or gaps, several filler elements, of a particularly elastic material, in this instance designated by numeral references 11, 12 and 13 and suitably covered at the lower part by a tread, respectively 11a, 12a and 13a.
  • each of the elastic filler elements in relation to the various stresses foreseen for every outsole zone, can have an elasticity degree different from the others and, in any case, the flattening would be limited by the coming into bearing position of the sole 10, which is anyway of a more rigid material.
  • a plurality of helical steel springs 14 may be inserted and arranged so as to integrate the elasticity of the material on the top.
  • Insertion of the steel springs may regard all or part of the elastic filler elements of an outsole, as well as elastic fillers of the other embodiments illustrated in the other figures.
  • a further advantage of the present invention is given by the possibility to have a different distribution of the footwear and elastic filler elements, which by being fixable in adapted seats and through adapted adhesive substances, or with known coupling means, would be provided with different elasticity degrees allowing to personalize the outsole according to the individual weight and requirements of the athlete.
  • Such a prerogative may be advantageous even from an economical point of view because, in the same way, it is possible to replace periodically the elastic filler elements, or rather those parts which are more exposed to wear.
