Description

  The present invention relates to footwear having a breathable sole.

  Walking and standing cause swelling and stuffiness of the feet, which usually causes significant discomfort over time. To reduce this discomfort, the use of shoes and fitted soles has been continuously studied for years.

  Since the problem is known to be stuffy, there is an increasing number of shoes with perforations on the top surface. However, even with such modification, it is not possible to prevent the feet from becoming noticeably stuffy from the sole portion that is completely blocked from the outside.

  The sole of a shoe typically contains multiple layers of fully waterproof synthetic material, as it is necessary to hold an insole that is used to dampen shocks caused by walking on the ground. It is.

  These shock absorbing insoles are, for example, air cushions, gels held in envelopes or special polymers.

Most shoes available today have a structure with an opening to ventilate the upper part of the foot, but the sole part is hermetically confined in the mold of the sole, so no one can arch The problem of stuffiness occurs. This is associated with the following associated discomfort:
-Large swelling of the foot with excessive thermal sensation,
-Increased humidity and increased friction inside the shoe,
-80% increased foot sweating from the sole,
-Rapid degradation of the insole with the development of bacteria and odors.

  Accordingly, the present invention aims to solve these major problems by providing footwear with ventilation through the inner member of a normally shoe-tight shoe in addition to conventional ventilation through the shoe upper. And

The present invention relates to footwear including a bottom structure formed by a plurality of superimposed soles positioned between a foot and the ground, and an upper, wherein each of the soles is perforated, and receives water and air. It is designed to pass through and is made of a washable synthetic material, each of the superimposed soles:
-An outsole made of rigid rubber and / or polymer that absorbs shock well and in contact with the ground,
-Midsole,
An insole, preferably formed of two layers, removably molded and absorbing shock, preferably comprising at least one of the following components, advantageously a combination thereof: Features:
-A member formed by a lattice membrane bonded and sewn to the outsole;
-A member formed by a mesh film, which, when these two members are combined, is held with the lattice film and placed above the lattice film with respect to the ground. When used alone, the mesh film is bonded and sewn to the outsole.

  Footwear must include all types of shoes, such as sports, leisure, sandal type outdoor, or typical shoes that can be worn with a suit.

There are several advantages of footwear according to the present invention:
-Ventilation by the inner part of the shoe avoids excessive stuffiness of the sole and keeps the humidity level in the sole low;
-Brings high comfort to pedestrians by keeping the soles dry and ventilated,
-Bacteria and foul odors can be avoided by draining moisture while walking and when shoes are not being used,
-All soles that make up the shoe are washable and quick-drying, making maintenance easy.
-The bottom structure of the shoe made of different soles with different materials and different porosities makes it possible to prevent debris and dust from entering the shoe while allowing air and moisture to pass through. Particularly effective are multilayer structures,
-The shoe already includes a sole and a set of materials that reliably attenuate the shock, since its manufacture, so in many cases today it is ensured that the shock waves transmitted from the heel to the spine during walking are sufficient. The pedestrian is wearing an additional sole for damping, but this need not be added.

  Other features and advantages of the present invention will become apparent from the following description with reference to the accompanying drawings, which are shown as non-limiting only.

It is sectional drawing of the footwear by this invention.

  Footwear as described below comprises a structure at the bottom, i.e. located between the foot and the ground when the shoe is worn, and formed by a plurality, preferably at least three superimposed soles. . Shoe structures that are produced by a combination of several layers sewn or glued are known per se. The upper part of the shoe constituting the footwear, i.e. the upper, is formed in a conventional way by textile parts stitched or bonded together, so that the upper can be tied in a typical manner. There is an opening on the front surface.

  Such a shoe is shown in FIG. 1 along with various construction soles of the present invention.

  According to the invention, this footwear is characterized in that each sole is perforated and allows water and air to pass through, and that each sole is made of a washable synthetic material. To do.

  Air and water can flow through the sole between the exterior and interior of the shoe and in the opposite direction, as indicated by the arrows in FIG.

Also, according to the present invention, referring to FIG. 1, the sole is arranged as follows:
-An outsole 1 made of rigid rubber and / or polymer that absorbs shocks well and makes contact with the ground,
-Midsole 2,
An insole 3 which is preferably formed of two layers, is removably molded and absorbs shocks.

  In accordance with the present invention, the outsole 1 comprises at least two openings or slots, preferably a set of small sized openings and slots, typically having an opening and slot length of 2 to 300 millimeters. And the width must be limited to a maximum of 8 millimeters to avoid the passage of pebbles.

  By setting it as such a small dimension, although air and water can be passed, it can prevent clogging and gravel from clogging an opening part.

  Preferably, the opening or slit is provided in the recessed portion 4 of the outsole 1.

  The outsole is advantageously made of a rigid and wear resistant material such as neoprene EVA or polyurethane or a combination of these materials. In order to improve this resistance, the outsole is reinforced in the wear region by a rubber member, possibly reinforced with carbon. With such a configuration, it is possible to absorb more excellent impacts while obtaining durability thanks to the rubber parts.

  The geometry of the openings and slots contained in the insole is preferably defined to allow air and water to pass in an optimal manner while preventing objects or pebbles from entering through the outsole. . When choosing the slot geometry, consider what is required for the natural movement of the foot while facilitating the flexion movement required by such shoes. The geometry also takes into account the general robustness of the sole to avoid this, as too many slots placed in the wrong place will weaken the outsole. The size and shape of the slot is designed to avoid this as the sole may begin to tear and may gradually deteriorate with use.

According to the invention, the midsole 2 is preferably constituted by at least one of the following components, advantageously a combination thereof:
A member formed by a lattice film 5 bonded and sewn to the outsole 1;
A member formed by the mesh film 6 and, when these two members are combined, a member held together with the lattice film 5 and disposed above the lattice film with respect to the ground. The mesh film 6 is bonded and sewn to the outsole 1 when used alone.

  The lattice film 5 allows optimal passage of air and water while protecting the foot from pebbles and other external objects.

  Adhesion of one or the other membrane to the outsole is performed so that no adhesive is applied to the portion of the membrane that coincides with the opening and slot of the outsole so as not to block the perforation of the membrane. .

  The mesh film 6 makes it possible to cover the lattice film 5 while providing comfort to the wearer for aesthetic and protective reasons. This midsole makes it possible to insert between the two membranes, if necessary, any material that allows for better shock absorption and / or shock wave dispersion as well as latex parts or gels, More generally, it also makes it possible to incorporate an insert that can optimize the comfort of the shoe.

  Therefore, according to the present invention, it is possible to insert an insert that enables shock absorption and / or shock wave dispersion between the lattice film 5 and the mesh film 6.

  The insert is advantageously provided with perforations to allow moisture and heat to pass through the various soles between the interior and exterior of the shoe.

According to the present invention, the insole 3 in contact with the foot includes the following two layers:
-A lower layer 7 made of EVA in contact with the underlying membrane,
A treated textile upper layer 8 on which the foot rides, said member being glued and / or sewn to the lower layer 7;

  According to the present invention, the textile upper layer 8 is treated to reduce the generation of bacteria and odors. The treatment can be carried out after the production of the fabric or on the fabric fibers themselves before weaving. This fabric member allows sweating to be discharged.

  This insole 3 is designed to improve comfort and shock absorption, and the insole is an adhesive member made of latex, gel or the like, if necessary, in order to improve shock absorption and / or comfort characteristics. Advantageously, it is molded together with EVA. The insole is naturally completely perforated.

  The upper part of the shoe, i.e. the shoe upper 9, is made of perforated fabric made of a washable synthetic material so that moisture and heat are expelled from the upper part in the usual manner.

  Multiple variations of the footwear are possible, and the footwear can include a variety of materials, even though the listed synthetic materials are preferred, and the thickness of the various soles and component layers is beyond the scope of the present invention. It can change without doing.

  The number and size of the perforations in each sole can be selected in a wide range and can be adjusted according to the material used, and the position, geometry and size of the perforations are within the scope of the present invention. It can be made in accordance with a plurality of forms without departing from the above.

  The shoe can of course include various styles of lacing, various exteriors and reinforcements on the shoe upper without departing from the scope of the present invention.

  The various soles and layers can be adjusted to each other, without limitation, according to techniques known in the art, for example, by gluing or sewing.

  Of course, the present invention is not limited to the embodiments described and illustrated by way of example, and the present invention includes technical equivalents and combinations thereof.
