Definitions

  • the present invention relates to a shoe with plantar arch support.
  • Shoes are already known in which at the plantar arch there is a shaped raised portion designed to support the plantar arch during walking.
  • the effectiveness of the raised portion is only partial, owing to the fact that it actually only acts as a cushioning element but does not support the plantar arch.
  • the aim of the present invention is therefore to provide a shoe in which the sole is conceived so as to provide a contrasting thrust on the plantar arch when the arch is subjected to forces during walking.
  • an object of the present invention is to provide a shoe whose structure can be manufactured without having to resort to special equipment, using instead conventional methods, so as to provide a product which offers improved performance but remains cheap.
  • a shoe characterized in that it comprises a sole made of rubber-like elastic material in which, at the heel and at the front region of the sole, a rear chamber and a front chamber are provided which contain a fluid, said chambers being connected one another by a passage which lies on the inner side of the shoe and at the plantar arch, said passage being shaped so as to curve upward and form a vault for supporting said plantar arch when, during walking, the fluid flows from said rear chamber toward said front chamber.
  • the reference numeral 1 generally designates a shoe which comprises a sole 2 made of rubber-like elastic material which is associated, during molding, with an upper 3.
  • Two chambers 4 and 5 are formed in the sole 2, respectively occupy the front part of the sole and the rear part of the heel, and contain a fluid, specifically air or a similar gaseous mix.
  • the chambers 4 and 5 are mutually connected by a passage 6 which runs along the inner side of the shoe, at the region where the supporting raised portion or plantar insert 7 is normally located.
  • the passage 6 has an upward arc-like shape which forms a vault and is laterally supported by a full-thickness region 8 of the sole toward the outside and by a thinner wall 9 toward the inside.
  • the passage 6 is furthermore supported in a downward region by an arc-like portion 10 of the sole which tapers toward the front under the front chamber 4 and toward the rear under the chamber 5.
  • the cross-section of the passage 6 is shaped like a flattened tube and the top of the vault that it forms is in tangent contact with the lower face of the plantar insert 7.
  • the invention perfectly achieves the intended aim and object.
  • the supporting action occurs at the time of most intense stress for the plantar arch, so as to avoid excessive stresses and fatigue of the muscles of the foot. This supporting action is proportional to the weight that bears onto the sole.
  • fluid-containing tubular rubber inserts 11 are arranged inside the chambers 4 and 5 and are designed to regulate the stability of the sole, since they hinder the transfer of the fluid inside the chambers 4 and 5.
  • the sole 2 is manufactured using conventional systems for the injection-molding of suitable plastic materials, for example by applying to the bottom of the shoe a bladder which forms the chambers 4 and 5 and the passage 6 and by performing an injection-molding process to cover it with a layer of rubber-like elastic material or the like.
  • a liquid or a gas can be used as transfer fluid, depending on the expected compression stresses.
