Definitions

  • This invention relates to a method for generating an elastic membrane for supporting the whole of the plantar arch integrated in the shoe and the membrane resulting from this method, so that said membrane has a specific geometric form that adapts to the foot and provides a substantial increase in convenience and comfort for the user, reducing muscle fatigue caused by walking.
  • this specific form enables an air chamber to be created between the insole and the outsole of the shoe, providing high transpiration for the foot.
  • insoles some for medical purposes, aiming to correct defects in feet and the way of walking and others for the convenience and comfort of the user.
  • the majority of these are flexible in nature in order to easily adjust to the shoe and are made of plastic materials.
  • the utility model ES0271756 U discloses an insole made of plastic flexible laminar material.
  • these insoles are often not sufficiently elastic, so that the foot rests on an element that is too rigid, which sometimes may be excessively heavy.
  • the fact of incorporating these insoles in the shoe increases the height of the heel and the zone of the plantar arch, taking away part of the space normally designed for housing the foot.
  • this invention is for integrating a membrane in the shoe so that it forms an active part thereof, not as a removable insole, but tightly coupled to the shoe.
  • Patent ES1058795 discloses an outsole with an incorporated insole and pluggable ventilation thereunder that comprises a body of sole with a perimeter lateral wall that surrounds the interior space, with a plurality of orifices; and an interchangeable insole, configured and dimensioned to be complementary with the interior housing space formed in the body of the sole.
  • the insole described above does not provide complete support to the bottom of the foot, which is one of the fundamental objectives of this invention, since in this way the biomechanical functioning of the foot is improved.
  • the increase in the supporting surface area and the elasticity of the sole will considerably improve the pumping effect necessary to ensure correct venous return, thereby improving the convenience and comfort during use and reducing muscular fatigue caused by walking.
  • This invention consists of incorporating into the shoe an elastic element with a specific geometry, which adjusts to the foot and has sufficient elasticity.
  • This element is integrated into the shoe as an active part thereof and not as an insole or removable element.
  • the advantage of this system is that it does not take away space from the foot, as it is integrated in the shoe and does not increase the height of the heel or of the area of the plantar arch. Consequently, it allows an increase in the supporting surface area, improving the biomechanical functioning of the foot.
  • a size 42 shoe was chosen and a three-dimensional plantar scan was performed of the feet of 150 people who had this size of foot. Then, the geometry of the membrane was designed and the system for fixing together the insole with the membrane to the sole of the shoe was validated. The transpiration system was validated by means of actual trials, firstly of the membrane independently from the shoe, and later of the shoe itself.
  • the method consists of scanning and identifying the defects found in feet, providing a test result bank, which enable the creation of a membrane type.
  • a test result bank which enable the creation of a membrane type.
  • the purpose of this project is to develop a new line of footwear that enables a substantial increase in convenience and comfort in use, reducing muscular fatigue caused by walking, adjusting the sole in the interior of the shoe to the foot of the user. It is a shoe that is suitable for all types of adults, in good health or with incipient problems, for which it is a preventative solution, accommodative and providing substantial improvement.
  • the characteristic form of the membrane and the material employed is such that when supporting the foot, the membrane yields and ensures that the whole sole of the foot is supported on the sole of the shoe, improving the user's comfort with respect to current footwear. On lifting the foot, the membrane recovers its original position, creating an air chamber between the membrane and the sole or insole of the shoe.
  • the invention is not a solid piece, such as traditional insoles, but a laminate that leaves a hollow space between the sole and the insole, in contrast to the solid or robust pieces of conventional insoles. In addition, it provides higher elasticity or less resistance to the pressure of the foot, achieving correct functioning and less weight than insoles.
  • the hollow or cavity created by the characteristic form of the membrane when not bearing weight is full of air.
  • the air housed in this cavity is displaced, leaving either through the sole of the shoe or through the orifice or orifices provided in the interior sides of the shoe for this purpose, and protected by a membrane that enables the flow, exchange and renewal of air contained in the hollow of the plantar arch and inhibiting the passage of water from the exterior to the interior.
  • This invention relates to a method for generating an elastic membrane which gives support to the whole plantar arch integrated in the shoe as well as the membrane resulting from this method.
  • the method comprises at least the following stages:
  • a membrane (1) is obtained with characteristics that improve the quality and comfort of the insole assembly with respect to those already available, in addition to increasing the surface area for support of the foot, which is completely supported on the insole that acquires the arched form of the membrane (1). Also, this is a membrane made up of a laminate, in contrast to the solid or robust pieces of existing insoles, providing elasticity or less resistance to the pressure of the foot, thereby achieving a correct functioning.
  • the membrane (1) is constituted by a plastic and elastic flexible laminar material, which is preferably a composite of polypropylene with carbon loads. The membrane has a geometric form missing the toe cap but with heel (3).
  • the membrane can be provided with any fixing element, preferably by way of a tongue, flap or any other that is suitable.
