Definitions

  • This invention relates to breathable footwear (4), in particular for applications to ski boots, off-track ski boots, telemark, snow board as well as sports shoes in general, and related production method.
  • breathable footwear is known in the sector that is provided with internal membranes that promote the breathability of the foot perspiration and avoid the pooling of sweat.
  • Comfort must be achieved by creating a thickness of soft material that prevents direct contact between the user's foot and the rigid shell, typically made of plastic or other materials.
  • Thermal insulation is essential in order to provide comfort while skiing/walking and to prevent the foot from becoming too cold. This aspect is essential both in applications on boots and, for example, but not only, in the field of trekking footwear.
  • water repellency is essential because, in the case of infiltration of water/snow inside the boot, it is necessary to prevent the user's foot from getting wet: in fact, in this case, as seen, the comfort and temperature of the foot would be significantly reduced because the exchange of heat with the outside would increase.
  • thermal insulation and water repellency are often mutually incompatible with the breathability of the foot.
  • breathable footwear comprises a waterproofing portion/membrane, substantially a closed bag, which is sewn and fixed internally to the upper by means of adhesives and/or stitching.
  • the seams cause holes through which the waterproofing portion/membrane loses at least partially the waterproofing properties that allow the vapour to escape but prevent the entry of water and liquids.
  • the seam holes constitute the points through which external liquids can penetrate through the waterproofing membrane which, therefore, loses the properties of waterproofing and/or water repellency.
  • Adhesives create a layer of non-breathable material that causes pooling of water or vapour inside the waterproofing and breathable portion.
  • the footwear is a closed gap that creates pooling of sweating or, indeed, does not prevent the entry of water from outside: as seen, sweating, as well as the entry of water from outside, is one of the main causes of loss of comfort, as it can generate blisters and reduce the thermal insulation of the shoe.
  • reference number 4 globally indicates a breathable footwear article, in particular for applications on ski boots, off-track ski boots, telemark, snow board as well as sports shoes in general.
  • the breathable footwear 4 comprises a waterproofing and breathable portion 8, at least partially sealed so as to identify a containment volume 12 for a foot of a user.
  • the waterproofing and breathable portion 8 is shaped so as to allow the escape of water or vapour to the outside of the footwear 4 and the containment volume 12 and so as to prevent the entry of water or vapour coming from the outside of the footwear 4 inside said containment volume 12.
  • the waterproofing and breathable portion 8 is formed in such a way as to be folded and sealed as a bag, having a front access portion 16 so as to cover an associable user's foot at least up to the height of an ankle of said foot.
  • said waterproofing and breathable portion 8 is folded and sealed by seams 20; preferably those seams 20 are waterproofed.
  • said seams 20 are waterproofed by overlapping waterproof adhesive tape 24.
  • the waterproofing and breathable portion 8 comprises a membrane, for example, of the GORE - TEX® type.
  • the breathable footwear 4 also comprises an upper 28 arranged as a covering of said waterproofing and breathable portion 8, wherein the upper 28 is at least partially perforated to facilitate the escape of water or vapour from the waterproofing and breathable portion 8.
  • this upper 28 is water-repellent, so as to prevent the entry of water or vapour which would pool in the gap between the waterproofing and breathable portion 8 and said upper 28 itself.
  • the waterproofing and breathable portion 8 is mechanically connected to the upper 28 by means of at least one tape 32, for example made of thermoplastic or other material, comprising at least a first flap 36 attached to the waterproofing and breathable portion 8 by means of gluing or heat welding, and comprising at least a second flap 40 fixed to the upper 28 by means of gluing, thermoforming or sewing.
  • tape 32 for example made of thermoplastic or other material
  • tape must be considered in the broad sense, meaning not necessarily a long and thin strip but any connection element, even thread-like, suitable to connect the waterproofing and breathable portion 8 and the upper 28 with each other.
  • the tape 32 is shaped so as to permit a clearance or gap between the waterproofing and breathable portion 8 and the upper 28.
  • the tape 32 is shaped so that the connection between the waterproofing and breathable portion 8 and the upper 28 is of the slack type, allowing a mutual movement between the connected parts, but at the same time ensures the locking on the longitudinal axis X-X of the waterproofing and breathable portion 8 avoiding the use of glues.
  • the tape 32 may be positioned in different positions of the waterproofing and breathable portion.
  • the tape 32 is positioned at one side edge 44 of the waterproofing and breathable portion 8, arranged parallel to a main direction of longitudinal extension X-X of the breathable footwear 4.
  • the tape 32 is made of thermoplastic material. Production with thermoplastic material facilitates the heat welding of the tape on portions of the waterproofing and breathable portion 8 and/or on the upper 28.
  • the tape 32 can be provided with a plurality of holes (not shown) that improve its breathability.
  • Said holes enhance the breathability of the breathable footwear 4 and, in particular, do not interfere but rather facilitate breathability, from the inside towards the outside of the footwear, provided by the waterproofing and breathable portion 8: in other words, the vapour coming from the containment volume 12 and from the waterproofing and breathable portion 8 can freely exit also in correspondence of the first flap 36 of attachment of the tape 32, so as to reach the upper 28 and be able to escape through the latter.
  • the upper 28 comprises a plurality of overlapping and breathable components 48, suitable to form portions of footwear having different thicknesses, materials and/or stiffnesses.
  • said components 48 may comprise padding of various types, such as anti-chafing patches, inserts and coverings arranged in correspondence of particularly exposed parts of the foot, such as the malleolus, the tip of the foot, the heel and the like.
  • These components 48 have, in their outer part in contact with an inner wall 76 of a ski boot 64, the peculiarity of being composed of hydrophobic materials.
  • At least one of said overlapping and breathable components 48 of the upper 28 is made of a thermo-formable material.
  • Thermo-formable material means a material suitable to be formed under the action of heat so as to maintain the conformation also following its subsequent cooling.
  • the footwear are thermo-formed by fitting the footwear to the user: in this way, the footwear can actually take the shape of the user's foot and therefore can be shaped to measure.
  • thermoforming In order for the thermoforming to take place in a comfortable manner, it is necessary that the material forming the components 48 is thermo-formable at a sufficiently low temperature so that they can be heated, and thus thermo-formed, while the user is wearing the footwear, without being his being burned.
  • the footwear 4 is composed of several parts, such as for example an insole 52, which is also preferably provided with holes and suitable to realise a comfortable support for the sole of the foot.
  • the shoe may include a tongue 56 preferably provided with holes, and an upper structure 60, also preferably provided with holes, suitable to embrace the tibial zone of the user.
  • the insole 52, the upper structure 60 and the tongue 56 can be made of a thermo-formable material, as described above.
  • the breathable footwear 4 according to this invention is suitable for use in applications on boots, off-track ski boots, telemark and snow board.
  • Said boots 64 typically include a shell 68 and a cuff 72, hinged to the shell 68, in correspondence of the malleolus of the user's foot.
  • the boot 64 defines an internal compartment that houses the breathable footwear.
  • Said footwear 4 is housed inside the compartment of the ski boot delimited by an inner wall 76 of the ski boot 64 so as to make an outer layer 80 of the footwear 4 face said inner wall 76 of the ski boot 64.
  • the breathable footwear 4 is interposed between the foot of the user and the boot 64.
  • Said method comprises a waterproofing and breathable portion 8 divided into at least two separate parts 8',8" ( Figures 3 to 4 ).
  • a first flap 36 of the tape 32 is applied to the waterproofing and breathable portion 8 by means of gluing or heat welding.
  • the waterproofing the joins of said counter-shaped flaps is performed. This waterproofing may, for example, take place through the application of waterproof thermal adhesive tape 24 to cover said seams/joins 20 ( Figure 6 ).
  • An upper 28 is arranged so as to cover said waterproofing and breathable portion 8 ( Figures 8 to 9 ), wherein the upper 28 is at least partially perforated to facilitate the escape of water or vapour from the waterproofing and breathable portion 8.
  • the step of mechanically connecting the waterproofing and breathable portion 8 to the upper 28 by means of at least one tape 32 ( Figures 4 , 5 , 6 and 7 ), wherein at least a first flap 36 of the tape 32 is attached to the waterproofing and breathable portion 8 by means of gluing or heat welding, and at least a second flap 40 of the tape 32 is attached to the upper 28 by means of gluing, heat welding or sewing ( Figure 9 ).
  • the breathable footwear according to the invention allows overcoming the drawbacks presented in the prior art.
  • the breathable footwear according to the invention allows meeting the user's needs in terms of breathability of sweat at the same time comfort, thermal insulation and waterproofing from the outside.
  • the presence of tapes associated to the waterproofing portion by means of gluing and/or fusion firstly allows avoiding puncturing the fabric of both the upper and the same waterproofing portion, so as not to compromise the waterproofing/water repellency.
  • this type of attachment does not interfere with the function of the waterproofing and breathable membrane of allowing the evaporation of sweat, so as to avoid its pooling in contact with the foot.
  • this type of attachment by not requiring a direct contact between the waterproofing and breathable portion/membrane and the upper, allows the possibility of leaving a gap between said portion/membrane and the upper.
  • a gap improves the breathability of the foot, allows the sweat to escape through suitable holes passing through the upper and also creates a further thermal barrier that insulates the foot from the outside environment.
  • a waterproofing portion such as, for example, an inner water-repellent membrane, ensures the water repellency of the shoe, i.e., it prevents water from penetrating from the outside of the shoe and coming in contact with the user's foot.
  • the footwear is light overall and comfortable to wear.
  • the method of producing the footwear is also simple, fast and inexpensive to implement.
  • the application of the tapes or inserts on the membrane/waterproofing and breathable lining is realised in a rapid and convenient manner, even before sewing the lining itself to the bag.
  • the subsequent attachment of the tapes or the inserts to the upper may in turn take place by gluing or heat welding but also by sewing, in a fast and convenient manner, since it is not required to tighten the membrane and upper in contact, but the tapes or inserts allow a certain slack between the parts to be connected.
