Definitions

  • the present invention relates to the field of footwear, such as shoes, boots, boots or the like, and relates to such an article footwear fitted with an isolation device.
  • a solution offered by article manufacturers footwear consisted in making holes in the rod at determined locations, in particular at the front part of the footwear.
  • footwear which is provided a molded outsole directly on the upper, drive usually the highest risk of ailments high and generate the most discomfort sensations pronounced.
  • the object of the present invention is to overcome these disadvantages.
  • the single figure in the accompanying drawing represents a footwear 1 having a outsole 2, a first sole 3 and a upper 4.
  • this article of footwear 1 is advantageously provided with an isolation device 5 arranged under the first sole 3.
  • the isolation device 5 consists of preferably by an elongated element 6, advantageously arranged at least under the support area of the plant of the foot of the user and delimiting, under the sole 3, at least one air space.
  • This elongated element 6 is in the form a false sole fixed by its periphery 7, by welding, gluing or stitching on the underside of the sole first 3 and provided with spacing means 8, preferably in the form of ribs, delimiting with said first sole 3 air spaces.
  • the spacing means 8 extend transversely to the axis longitudinal of the elongated element 6.
  • the flexibility longitudinal of the elongate element 6 is ensured, so that it doesn't hinder flexibility of the entire footwear, the resulting flexion of walking only having the effect of modifying the geometry of the spaces between the ribs 8.
  • the means 8 in the form of ribs are advantageously provided with at least one interrupt in the form cutting making communication with space of neighboring air delimited by means 8, or rib, according to or preceding.
  • the device 5 allows isolation of the sole against release of heat occurring during walking due to friction between the outsole 2 and the outsole 3, by creating an insulating air pocket under the sole.
  • the first sole 3 is provided with perforations 9 over all or part of its surface extending above the air space or spaces delimited by the means 8 or ribs provided on the elongated element 6.
  • this isolation device 5 allows a reduction in the radius of curvature of the outsole and a reduction in the thickness of this last at said device 5. It follows that, in the case of an embodiment of the outsole 2 by injection, for example of polyurethane, this can be reduced to the level of said device 5.
  • the space or spaces delimited between the first sole 3 and the elongated element 6 can be partially filled a solid material with deodorant and / or desiccant action having long-lasting effects. So, he is possible to simultaneously deal with the problems of corresponding sweating and odor release.
  • the elongate element 6 can be provided, on the one hand, with a upper closing part delimiting with the part lower one additionally flat and, on the other hand, a means with suction valve and a discharge means also with valve, said means opening respectively, the means of suction outside the article footwear or inside it and the means of repression, in the form of nozzles, under the sole of the foot and / or toes, as well as possibly near the heel.
  • a means with suction valve and a discharge means also with valve said means opening respectively, the means of suction outside the article footwear or inside it and the means of repression, in the form of nozzles, under the sole of the foot and / or toes, as well as possibly near the heel.
  • the air circulation or ventilation generated by the device 5 thus formed is particularly important in the case of a movement of the user, due to significant variations in the pressure exerted by the user's foot on the first sole 3, simultaneously with the bending of the latter, during the foot support.
  • Air distribution under the sole and / or under the toes can be performed by means air supply and distribution, in the form of channels, of grooves or grooves, converging towards the affected areas.
  • the isolation device 5 with an air circulation pump arranged in the part heel of the sole and connected by a conduit to the air space defined by the elongated element 6, said pump sucking air outside the footwear or inside it. So it is possible to carry out a forced circulation of air inside footwear, with or without regeneration said air, which is delivered under the sole of the foot and / or the toes through the perforations 9.
  • Outsole 2 can be made in polyurethane foam and have a single layer structure or multilayer with variable density.
  • the invention it is possible to carry out an article of footwear allowing insulation of the sole of foot against generation of heat when walking as a result of friction between the first and wear soles and possibly allowing, in addition, ventilation of the sole and / or toes.
  • the invention also provides a possibility of treatment of exudations and / or smells. This results in a significant improvement in comfort for the user and a significant reduction in risks contraction of foot conditions.
