• the casing 42 of the boot At the level of the casing 42 of the boot, it comprises a buttress 41 which reinforces the casing from the outside.
• the ventilated shoe 1 also comprises a ventilation system defined jointly by the soles 2, 3.
• the outsole 2 and the comfort sole 3 thus form a ventilation network 21, 31 comprising at least one plantar channel 21.
• the or each plantar canal 21 of longitudinal extension extends between the wear soles 2 and comfort 3 from an area corresponding to the heel to an area corresponding to the articulation between the metatarsal and phalanges of the foot.
• This pumping effect is facilitated by an increase in the height of the space between the outsole and the comfort sole in the vicinity of the inlet of the air passage 45.
• the pumping chamber thus helps the circulation of air.
• the pumping chamber may have various shapes depending on the material of the comfort sole 3.
• the shape of the pumping chamber (for example annular or cylindrical ) and the material of the comfort soleplate 3 are chosen to ensure a firmer under the wearer while optimizing the desired pumping function.
• the or each plantar channel 21 is preferably formed in the outsole 2, on the surface facing the interior of the shoe 1.
• the plantar channel 21 thus forms a groove in the outsole 2.
• transverse channels 31 may preferably be formed in the comfort sole 3 on the surface facing the outsole 2. These channels transverse 31 forming grooves used to circulate the air between the channels 21 and up to the periphery of the sole comfort 3 and thus provide ventilation of the entire sole of the foot.
• the outsole 2 and / or the comfort sole 3 may have come from the age of age together with the corresponding s ucts.
• the buttress 41 has at least one orifice 43 in its upper part, the buttress 41 and the casing 42 forming two membranes, respectively outer and inner. Spacer elements 44 are provided between these two membranes.
• the inner membrane 42 is thus the membrane closest to the inside of the shoe 1.
• the outer membrane 41 is the membrane in contact with the ambient air.
• the outer membrane 41 is preferably substantially watertight. If a padding 5 is provided in the casing of the shoe 1, it is placed against the inner membrane 42 inside the space receiving the foot, the padding 5 being located between the inner lining 6 and the membrane interior 42.
• the spacers 44 separate the two membranes 41, 42 to form between them the air passage 45 extending over the height of the casing.
• the orifice 43 connects the outside of the boot 1 to the air passage 45, that is to say that it is formed through the buttress 41.
• the casing 42 and the buttress 41 are not stopped at the outsole 2. They are bent towards the longitudinal direction of the outsole 2 in order to put in fluid communication the passage of air 45 and the plantar canal 21 at a generally horizontal end of said passage, thus formed by the continuation of the membranes 41 and 42 to the plantar canal 21.
• the role of the passage 45 is thus to allow the flow of air from the top of the casing to the plantar channel 21, formed for example in the outsole 2, under the comfort sole 3. It will be noted here that the rear region of the comfort sole 3 covers the membranes 41 and 42 forming the termination of the passage 45 on the plantar canal side 21.
• the casing 42 with its buttress 41 is a more rigid element than the lateral sides of the rod 4 and does not easily deform when walking or when conditioning the shoe 1 before marketing or when it is reset years. furniture.
• the formation of the air passage 45 inside the buttress makes it possible to ensure that the passage of air 45 does not clog easily. Indeed, if the air passage 45 was formed on the lateral sides of the rod 4, the air passage 45 could be deformed and its function altered.
• the air passage 45 may extend over a large part of the buttress 41, increasing the volume of air that can enter the interior of the shoe 1.
• the ventilation system 21, 31, 43, 45 of the boot 1 allows air to circulate from the outside of the boot 1 inwards via the orifice 43, the air passage 45 and the plantar canal 21, and in the other direction.
• the spacing elements 44 are preferably a plurality of projecting members 441, for example spikes, now spaced apart the two membranes 41, 42.
• These salient elements 441 can be individualized and fixed separately on an inner face of one of the membranes. 41, 42, or on both internal faces vis-à-vis.
• These projecting elements 441 can still be connected to each other and form a spacing element 44 in one piece.
• Such a spacing element 44 in one piece is fixed on an inner face, with respect to the air passage 45, of one of the membranes 41, 42.
• the salient elements 44 can still be fixed on the internal faces of the two membranes 41, 42.
• the salient elements 441 preferably have a height of between 1 mm and 5 mm, to ensure the passage of air 45 a width of the same order.
• the salient elements 441 perform a baffle function, limiting the risks of water entering the air passage 45, especially when walking in a pool or when the shoe is exposed to splashing.
• the membranes 41, 42 are preferably made of natural or artificial leather, waterproof canvas, rubber, etc. and have a thickness of, for example, between 0.3 mm and 1 mm.
• the orifice 43 or each orifice 43 may be located above the level of the pegs. Thus, if the user walks in a puddle, his foot remains dry as long as the water level does not exceed that of the holes 43.
• the ventilation system 21, 31, 43, 45 can be extended to the top of the rod 4, that is to say that the structure with the buttress 41 can be used for the rod 4 at the back of the boot to the top of it. Alternatively, it can stop at an intermediate height of the boot.
• the positioning of the orifice in the raised position has the advantage of not requiring the use of high-tech materials (for example waterproof but permeable to air), which reduces the cost Manufacturing.
• the materials of the different parts of the shoe 1 can be chosen from a wide and varied range of materials. In particular, it does not restrict the choice of materials forming the comfort sole 3 among the crosslinked materials adapted to the flow of air through them. In addition, it is not essential that the two membranes 41, 42 are airtight, the main thing being to promote a flow of air through the passage 45.
