Definitions

  • the object of the present invention is to implement a sole which overcomes the above- mentioned drawbacks, particularly which is suitable to improve the comfort of those who use the sole at least in correspondence with the sole part adapted to support the heel.
  • the exhaust element 4 preferably provides an outer arched wall 4C (fig. 9 A) and an inner arc-shaped wall 4B (fig. 3) suitable to be coupled flush with a section of the outer rear arc- shaped side wall 1C (fig. 9A) of the element 10 of the sole and with an arc-shaped section of the inner arc- shaped wall 1C (fig. 2) delimiting the through opening 2 on the side, respectively.
  • connection between the two elements 4 and 5 further stiffens crosswise the bridge element 5, at least in its rear part which is closest to the element 4.
  • the material this outer sole is made of is a material of a conventional kind for this part of a sole, for example it is a rubber, this kind of material has a comparatively high specific weight which affects the overall weight of the sole itself.
  • the extension of said outer U-shaped sole 13 is limited to only a portion PI (fig. 2) of the U-shaped arms provided in correspondence with the heel.
  • a portion 31A 3 IB 31 C (fig. 2) of the lower face of the arms 1A, IB, 1C which is closest to the opening 2, of the U-shaped sole remains visible, namely is not covered by the outer sole 13 and a portion 31 A' e 3 IB' (fig.
  • the outer sole 13 only covers an area from 30% to 70% of the face of the U-shaped arms 1A-B facing the ground.
  • the pads 19A-E start from a substantially flat body 19F which, along with the pads, forms the shock- absorbing element 19.
  • This flat body 19F is suitable to be housed flush and to be rigidly connected to (for example by gluing or by other customary methods known to those skilled in the art) in the seat IP (fig. 1) of the structural element 10.
  • This seat IP and the flat part 19F of the shock-absorbing element are shaped so that each of the pads 19A-E is entirely encircled by a flat portion of the flat part 19F so that the pads are steadily connected to the upper face IK (fig. 1) of the front portion of the structural element 10.
  • the part Zl of the sole provided in correspondence with the heel has a structural element 210, formed by one or more layers of plastic materials of the same type or of different type, which in correspondence with at least the heel area has an opening 202 closed by a wall 205' (or by a bridge element 205 of the same type described above) and comprising an exhaust element 204 for the air which may remain trapped in the cavity defined by the walls delimiting the opening 202 and by the closing wall 205'.
  • the forefoot part Z3 of the sole is of a conventional type and is therefore not described in detail.
  • This sole shows a forefoot part with improved shock-absorbing performance.
