Definitions

  • the present invention relates to a shoe with flexible plantar sole.
  • the object of the present invention is to eliminate the said drawbacks by proposing a shoe which prevents the heel from detaching during walking and absorbs its shocks.
  • a shoe comprising: - a rigid bottom or sole, for example of good thickness wood, with the upper face of the concave front part; a sole, for example made of multi-layer wood, thin and slightly flexible, arranged above the sole, with the only anterior part fixed on the corresponding anterior part of the sole, the remaining parts, median and posterior, being detached and raised relative to the sole; - A cylindrical helical spring, with compression and with substantially vertical action, inserted in correspondence of the rear end of the shoe, between said sole and said sole.
  • a thin layer of moderately elastic material is interposed between the sole and the sole, in the area at which they are fixed, to reduce the deformation angle of the sole. plantar, but without limiting its flexibility.
  • the band or strap which surrounds the foot above is fixed on the edges of the sole so as not to prevent the action of said elastic material.
  • a shoe with flexible plantar sole comprises: - a bottom or wooden sole 1 of good thickness, the upper face 2 of the front part of which is slightly concave; - a multi-layer wooden sole 3, thin and slightly flexible, located above said sole 1, with the front part fixed, that is to say glued, on the corresponding part 2 of the sole 1 and with the medial and posterior parts detached and raised relative to the sole, progressively increasing towards the posterior end of the hoof; a compression spring 4 in the form of a cylindrical helix, with vertical action, inserted near the rear end of the shoe, between said sole 1 and said sole 3.
  • a layer of elastic material 5 is advantageously interposed between the front parts of the sole and of the plantar sole to allow the angle of deformation of the plantar sole 3 to be reduced, but without limiting its flexibility.
  • the strip or strap 6 which surrounds the foot above, is conveniently fixed on the edges of the sole 3 so as not to interfere with the action of said elastic layer.
  • the flexibility characteristics of the plantar sole 3, the spring 4 and the elastic material 5 are chosen appropriately so as to allow vertical displacement of the rear end of the plantar sole 3 of a few mm. and preferably between 2 and 5 mm.
