Definitions
- the invention relates to footwear with an essentially air-impermeable outer layer.
- Foam shoes with a water and airtight outer layer are considered as an example.
- these can be ski boots with a foamed liner.
- Such shoes are usually lined with a textile lining. If the outer layer of the shoe is not permeable to air and water, the moisture cannot escape to the outside, but is absorbed by the lining. As the lining is not ventilated due to the air impermeability of the outer layer of the shoe, the lining cannot dry, but becomes sweaty, which leads to an uncomfortable feeling and causes a feeling of cold.
- the disclosed boot consists of an upper made of waterproof material, to which a rubber sole is molded at the bottom.
- the shaft part can be molded from plastic and has a number of openings through which outside air can flow in and out of the boot using the airstream.
- the boot disclosed in the abovementioned publication is equipped on the inside with a ventilation system which is constructed from a perforated material as the inner lining, a ventilation layer material and a mesh-like fabric which lies on the outside of the upper material.
- the object of the invention is therefore to provide footwear with an essentially air-impermeable outer layer which does not show the disadvantages in the prior art or only shows them to a significantly reduced extent.
- the ventilation layer material which is arranged between the side of the functional layer facing away from the foot and the air-impermeable outer material, enables the air to be supplied to the outside of the functional layer and, due to the ventilation effect, the foot moisture is removed. Because this ventilation layer material has air ducts which conduct in the longitudinal direction and air ducts which are connected to it and which extend in the transverse direction to at least one of its surfaces, air can reach all areas lined with the ventilation layer material. This can evaporate and dissipate sweat moisture.
- the ventilation effect is generally increased by the fact that the footwear provided with the ventilation layer material is frequently moved during its use, which leads to a pumping effect in the ventilation layer material, by means of which the ventilation behavior is increased.
- the orientation of the ventilation layer material is such that the longitudinal air guide channels are directed towards the open shaft end of the shoe or, for example if only the tongue is underlaid with ventilation layer material, towards the free end of the tongue, while the transverse air guide channels are directed towards the foot surface.
- the ventilation layer material can be structured entirely differently, for example open-pore, rib-like, nubbed, provided with webs, three-dimensional in a network or the like. It is only important that longitudinal air guiding channels and transverse air guiding channels connected to them are formed up to at least one surface.
- ventilation layer material and water vapor permeable, waterproof functional layer is suitable both for lining shoes and as a sole covering.
- shoes with a plastic outer layer such as Ski boots, foamed liners for ski boots and rubber boots.
- an inner sole and a tongue lining can be provided in one piece with the ventilation layer material. There is then a ventilation connection between the sole and the air outside the shoe.
- the combination of a waterproof, water vapor-permeable functional layer with ventilation layer material has further advantages.
- One such advantage is the cushioning effect, which can be very pleasant, for example in the case of ski boots.
- Another advantage is the achievement of flexible stiffening to prevent lumpiness of a shoe tongue, which is then better its desired Maintains position and does not slip from this position when wearing the shoe.
- the ventilation layer material should be pressure-stable. This means that it should not lose its ventilation function under the pressure load that occurs during normal use of the footwear provided with the ventilation layer material. This means that at such a normal loading pressure the air ducts should retain their shape to such an extent that they can still conduct sufficient ventilation air.
- the ventilation layer material can be made of a suitable plastic.
- Examples include polyamide, polypropylene and polyester, in monofilament or multifilament form, woven or knitted, or in the form of reticulated foam made from such a material.
- FIG. 1 shows an exemplary embodiment of a ventilation layer material in a schematic, greatly enlarged manner.
- three delta-shaped longitudinal webs 13 each form a spacer 11.
- a plurality of spacers 11, which are arranged essentially parallel and at a distance from one another, are provided on their underside by means of a plurality of transverse webs which run transversely with respect to the spacers 11, are spaced apart and essentially parallel to one another 17 connected.
- the spaces between two adjacent spacers 11 form longitudinal air guiding channels 19.
- the transverse air guiding channels 23 are also formed by the gaps between the spacers 11 and direct air flowing through the longitudinal air guide channels 19 to the plane located above the spacers 11 in FIG. 1.
- the transverse air guide channels 21 are formed by the spaces between the transverse webs 17 and guide air flowing through the longitudinal air guide channels 19 to the lower side of the ventilation layer material in FIG. 1. Moisture that forms below or above the ventilation layer material can be removed via the transverse air guide channels 21 or 23 and the longitudinal air guide channels 19.
- Fig. 2 shows a schematic representation of a shoe in front view, from which the front part is cut away, so that a cross-sectional view is possible.
- the thicknesses of the individual layers are not drawn to scale.
- the shoe 30 shown in FIG. 2 has a shaft 32 which is connected to an insole 33 in a manner not shown here.
- An outsole 35 is injection molded onto the underside of the insole, the side parts of which seal the fastening area between the shaft 32 and insole 33.
- the inside of the upper 32 and the insole 33 are lined with a ventilation layer material 3, which in turn is lined with an inner layer 37.
- the inner layer is a waterproof, Water vapor permeable functional layer of a known type.
- the inner layer can also consist of a laminate which has a functional layer which is lined on the inside with a lining. On its side facing the ventilation layer material 3, the laminate can additionally be provided with a protective layer for the functional layer.
- the shaft 32 is made of leather, there is a certain water vapor permeability, so that foot moisture formed in the shoe could get out through the functional layer and the leather shaft. Especially when the leather shaft has got wet, the ability of the leather shaft to let moisture in from inside to outside is very limited.
- the foot moisture that has come from the interior of the shoe to the outside of the functional layer can be dissipated via the ventilation layer material 3.
- the ventilation layer material 3 is oriented in such a way that its longitudinal air guide channels 19 are directed towards the upper end of the shaft, so that outside air can be supplied and moisture can be removed to the outside.
- the invention is particularly advantageous if the shaft 32 does not consist of a material that is not slightly permeable to air, but of an air-impermeable material, such as rubber or plastic. In this case, there is no conductivity for the foot moisture that forms inside the shoe.
- the ventilation effect of the ventilation layer material 3 has a particularly advantageous effect here.
- the invention is applicable and advantageous regardless of whether or not it is a shoe with a lace closure, as shown in FIG. 2.
- FIG. 3 schematically shows an example of a shoe which is only partially lined with ventilation layer material 3, namely in the area of a tongue 39.
- the ventilation layer material 3 is arranged on the inside of the tongue 39, on the inside surface of which there is again an inside layer 37. This again has a functional layer.
- the ventilation layer material 3 is again oriented in such a way that the longitudinal air guide channels lead to the upper, free end of the tongue and in this way form an air exchange between the shoe interior in the area of the tongue and the exterior.
- the entire shoe with ventilation layer material to line but only the inside of the tongue 39, and additionally to provide an insole that has ventilation layer material.
- the ventilation layer material arranged on the insole and on the inside of the tongue 39 are formed in one piece, so that longitudinal air guide channels are formed from the insole to the outside.
- transverse air guide channels 21 and / or 23 are designed such that they open at one end towards the foot and on the other hand are connected to longitudinal air guide channels 19, so that a ventilation connection is created between the foot surface and the air space outside the shoe.

Abstract
Description
Die Erfindung betrifft Schuhwerk mit im wesentlichen luftundurchlässiger Außenschicht.The invention relates to footwear with an essentially air-impermeable outer layer.
Man kommt häufig mit atmungsinaktiven oder atmungsschwachen Materialien direkt oder indirekt in Berührung, was an der entsprechenden Körperstelle zur Bildung von Schweißfeuchtigkeit führt.Frequently, you come into direct or indirect contact with breathable or weak breathable materials, which leads to the formation of sweat moisture at the corresponding part of the body.
Als Beispiel seien geschäumte Schuhe mit einer wasser- und luftdichten Außenschicht betrachtet. Dabei kann es sich insbesondere um Skistiefel mit geschäumtem Innenschuh handeln. Solche Schuhe sind üblicherweise mit einem Textilfutter ausgekleidet. Mangels Luft- und Wasserdurchlässigkeit der Außenschicht des Schuhs kann die Feuchtigkeit nicht nach außen ausweichen, sondern wird vom Futter aufgenommen. Da das Futter wegen der Luftundurchlässigkeit der Außenschicht des Schuhs nicht belüftet wird, kann das Futter nicht trocknen, sondern wird schweißfeucht, was zu einem unangenehmen Tragegefühl führt und Kältegefühl hervorruft.Foam shoes with a water and airtight outer layer are considered as an example. In particular, these can be ski boots with a foamed liner. Such shoes are usually lined with a textile lining. If the outer layer of the shoe is not permeable to air and water, the moisture cannot escape to the outside, but is absorbed by the lining. As the lining is not ventilated due to the air impermeability of the outer layer of the shoe, the lining cannot dry, but becomes sweaty, which leads to an uncomfortable feeling and causes a feeling of cold.
In der Bekleidungsindustrie sind wasserundurchlässige und wasserdampfdurchlässige mikroporöse Funktionsschichten verbreitet, wie sie in jüngerer Zeit für wasserdichte, aber dennoch atmungsaktive Bekleidungsstücke verwendet werden. In letzter Zeit ist man dazu übergegangen, auch Schuhe mit einer solchen Funktionsschicht zu versehen. Eine solche Funktionsschicht eröffnet zwar die Möglichkeit, daß Fußfeuchtigkeit durch die Funktionsschicht hindurch abgeführt werden kann. Wenn sich aber jenseits der Funktionsschicht nur luftundurchlässiges Material befindet, kann diese Feuchtigkeit nicht weitergeführt werden und staut sich somit, was dazu führen kann, daß die Fußfeuchtigkeit nicht vom Fuß weggeführt wird.In the clothing industry, water-impermeable and water-vapor-permeable microporous functional layers are widespread, as have recently been used for waterproof, but nevertheless breathable clothing items. In recent times, people have also started to provide shoes with such a functional layer. Such a functional layer opens up although the possibility that foot moisture can be dissipated through the functional layer. If, however, there is only air-impermeable material beyond the functional layer, this moisture cannot be carried on and thus builds up, which can lead to the fact that the foot moisture is not carried away from the foot.
Aus der Druckschrift EP-A1-0 177 892, die den gattungsgemäßen Stand der Technik zeigt, ist eine belüftete Sport-Fußbekleidung, speziell für Motorradfahrer, bekannt. Der offenbarte Stiefel besteht aus einem Obermaterial aus wasserdichtem Material, an das unten eine Gummisohle angeformt ist. Der Schaftteil kann aus Kunststoff geformt werden und weist eine Anzahl von Öffnungen auf, durch die unter Nutzung des Fahrtwindes Außenluft in den Stiefel hinein- bzw. hinausströmen kann. Der in der vorstehend genannten Druckschrift offenbarte Stiefel ist innenseitig mit einem Ventilationssystem ausgestattet das aus einem perforierten Material als Innenauskleidung einem Ventilationsschichtmaterial und einem netzartigen Gewebe aufgebaut ist, das auf seiner Außenseite an Obermaterial anliegt.From the document EP-A1-0 177 892, which shows the generic state of the art, a ventilated sports footwear, especially for motorcyclists, is known. The disclosed boot consists of an upper made of waterproof material, to which a rubber sole is molded at the bottom. The shaft part can be molded from plastic and has a number of openings through which outside air can flow in and out of the boot using the airstream. The boot disclosed in the abovementioned publication is equipped on the inside with a ventilation system which is constructed from a perforated material as the inner lining, a ventilation layer material and a mesh-like fabric which lies on the outside of the upper material.
Insbesondere dann, wenn diese bekannte Fußbekleidung nicht auf einem Motorrad oder bei geringer Fahrgeschwindigkeit getragen wird, ist mit einer Aufstauung von Schweißflüssigkeit im Stiefelinneren zu rechnen, was zu einem unangenehmen Tragegefühl führt.In particular, if this known footwear is not worn on a motorcycle or at low driving speeds, a build-up of sweat inside the boot is to be expected, which leads to an uncomfortable feeling.
Aufgabe der Erfindung ist es daher, eine Schuhwerk mit im wesentlichen luftundurchlässiger Außenschicht vorzusehen, das die Nachteile im Stand der Technik nicht oder nur in wesentlich vermindertem Ausmaß zeigt.The object of the invention is therefore to provide footwear with an essentially air-impermeable outer layer which does not show the disadvantages in the prior art or only shows them to a significantly reduced extent.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Schuhwerk mit den im Patentanspruch 1 genannten Merkmalen.The object is achieved by a footwear with the features mentioned in claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 13 angegeben.Advantageous developments of the invention are given in
Durch das Ventilationsschichtmaterial, das zwischen der vom Fuß abgewandten Seite der Funktionsschicht und dem luftundurchlässigen Außenmaterial, angeordnet ist wird die Luftzufuhr zur Außenseite der Funktionsschicht ermöglicht und infolge der Ventilationswirkung die Fußfeuchtigkeit abgeführt. Dadurch, daß dieses Ventilationsschichtmaterial in Längsrichtung leitende Luftkanäle und damit in Verbindung stehende und in Querrichtung bis zu mindestens einer seiner Oberflächen reichende Luftkanäle aufweist, kann Luft an alle mit dem Ventilationsschichtmaterial ausgekleideten Bereiche herankommen. Dadurch kann Schwitzfeuchtigkeit verdunsten und abgeführt werden. Die Ventilationswirkung wird im allgemeinen dadurch erhöht, daß das mit dem Ventilationsschichtmaterial versehene Schuhwerk während seiner Benutzung häufig bewegt wird, was in dem Ventilationsschichtmaterial zu einer Pumpwirkung führt, durch welche das Ventilationsverhalten erhöht wird.The ventilation layer material, which is arranged between the side of the functional layer facing away from the foot and the air-impermeable outer material, enables the air to be supplied to the outside of the functional layer and, due to the ventilation effect, the foot moisture is removed. Because this ventilation layer material has air ducts which conduct in the longitudinal direction and air ducts which are connected to it and which extend in the transverse direction to at least one of its surfaces, air can reach all areas lined with the ventilation layer material. This can evaporate and dissipate sweat moisture. The ventilation effect is generally increased by the fact that the footwear provided with the ventilation layer material is frequently moved during its use, which leads to a pumping effect in the ventilation layer material, by means of which the ventilation behavior is increased.
Die Ausrichtung des Ventilationsschichtmaterials ist derart, daß die Längsluftleitkanäle zum offenen Schaftende des Schuhs oder, wenn z.B. nur die Zunge mit Ventilationsschichtmaterial unterlegt ist, zum freien Ende der Zunge gerichtet sind, während die Querluftleitkanäle zur Fußoberfläche hin gerichtet sind.The orientation of the ventilation layer material is such that the longitudinal air guide channels are directed towards the open shaft end of the shoe or, for example if only the tongue is underlaid with ventilation layer material, towards the free end of the tongue, while the transverse air guide channels are directed towards the foot surface.
Das Ventilationsschichtmaterial kann gänzlich verschieden strukturiert sein, beispielsweise offenporig, rippenartig, genoppt, mit Stegen versehen, netzartig dreidimensional oder dergleichen. Wichtig ist nur, daß dabei Längsluftleitkanäle und mit diesen in Verbindung stehende Querluftleitkanäle bis zu mindestens einer Oberfläche hin entstehen.The ventilation layer material can be structured entirely differently, for example open-pore, rib-like, nubbed, provided with webs, three-dimensional in a network or the like. It is only important that longitudinal air guiding channels and transverse air guiding channels connected to them are formed up to at least one surface.
Der kombinierte Einsatz von Ventilationsschichtmaterial und wasserdampfdurchlässiger, wasserdichter Funktionsschicht, eignet sich sowohl zur Auskleidung von Schuhen als auch als Sohlenbelag. Dabei ist insbesondere an Schuhe mit Kunststoffaußenschicht, wie z.B. Skistiefel, geschäumte Innenschuhe für Skistiefel und an Gummistiefel zu denken.The combined use of ventilation layer material and water vapor permeable, waterproof functional layer is suitable both for lining shoes and as a sole covering. In particular, shoes with a plastic outer layer, such as Ski boots, foamed liners for ski boots and rubber boots.
Bei Schuhen kann es schon zu einer erheblichen Verbesserung der Tragfähigkeit führen, wenn sie nur teilweise mit dem Ventilationsschichtmaterial ausgekleidet sind, beispielsweise und vorzugsweise an der Schuhzunge.In the case of shoes, it can already lead to a considerable improvement in the load-bearing capacity if they are only partially lined with the ventilation layer material, for example and preferably on the tongue of the shoe.
Insbesondere bei Schuhen mit wasserdichter, nicht atmungsaktiver Sohle kann man eine Innensohle und eine Zungenauskleidung einstückig mit dem Ventilationsschichtmaterial versehen. Es besteht dann Ventilationsverbindung zwischen der Sohle und der Luft außerhalb des Schuhs.Particularly for shoes with a waterproof, non-breathable sole, an inner sole and a tongue lining can be provided in one piece with the ventilation layer material. There is then a ventilation connection between the sole and the air outside the shoe.
Neben der Ventilationswirkung hat die Kombination einer wasserdichten, wasserdampfdurchlässigen Funktionsschicht mit Ventilationsschichtmaterial noch weitere Vorteile. Ein solcher Vorteil ist die Polsterwirkung, die beispielsweise im Fall von Skistiefeln sehr angenehm sein kann. Ein anderer Vorteil ist die Erzielung einer flexiblen Versteifung zur Verhinderung von Lappigkeit einer Schuhzunge, die dann besser ihre gewünschte Position einhält und nicht beim Tragen des Schuhs von dieser Position wegrutscht.In addition to the ventilation effect, the combination of a waterproof, water vapor-permeable functional layer with ventilation layer material has further advantages. One such advantage is the cushioning effect, which can be very pleasant, for example in the case of ski boots. Another advantage is the achievement of flexible stiffening to prevent lumpiness of a shoe tongue, which is then better its desired Maintains position and does not slip from this position when wearing the shoe.
Das Ventilationsschichtmaterial soll in gewissem Umfang druckstabil sein. Das heißt, es soll bei der Druckbelastung, die bei normaler Verwendung des mit dem Ventilationsschichtmaterial versehenen Schuhwerks auftritt, seine Ventilationsfunktion nicht verlieren. Das heißt, bei einem solchen Normalbelastungsdruck sollen die Luftkanäle noch soweit ihre Form bewahren, daß sie noch ausreichend Ventilationsluft leiten können.To a certain extent, the ventilation layer material should be pressure-stable. This means that it should not lose its ventilation function under the pressure load that occurs during normal use of the footwear provided with the ventilation layer material. This means that at such a normal loading pressure the air ducts should retain their shape to such an extent that they can still conduct sufficient ventilation air.
Das Ventilationsschichtmaterial kann aus geeignetem Kunststoff hergestellt sein.The ventilation layer material can be made of a suitable plastic.
Beispiele hierfür sind Polyamid, Polypropylen und Polyester, in Monofilamentform oder in Multifilamentform, gewebt oder geraschelt, oder auch in Form von retikuliertem Schaumstoff aus derartigem Material.Examples include polyamide, polypropylene and polyester, in monofilament or multifilament form, woven or knitted, or in the form of reticulated foam made from such a material.

In Fig. 1 ist in schematischer, stark vergrößerter Weise ein Ausführungsbeispiel für ein Ventilationsschichtmaterial dargestellt. Dabei bilden je drei deltaförmig gebündelte Längsstege 13 einen Abstandshalter 11. Eine Vielzahl im wesentlichen parallel und mit Abstand voneinander angeordneter Abstandshalter 11 ist auf ihrer Unterseite mittels einer Vielzahl von bezüglich der Abstandshalter 11 quer verlaufenden, im Abstand voneinander angeordneten und im wesentlichen parallel zueinander verlaufenden Querstegen 17 verbunden. Die Zwischenräume zwischen je zwei benachbarten Abstandshaltern 11 bilden Längsluftleitkanäle 19. Damit in Verbindung stehen Querluftleitkanäle 21, 23, wobei die Querluftleitkanäle 23 ebenfalls durch die Zwischenräume zwischen den Abstandshaltern 11 gebildet sind und durch die Längsluftleitkanäle 19 strömende Luft zu der in Fig. 1 oberhalb der Abstandshalter 11 befindlichen Ebene leiten. Die Querluftleitkanäle 21 sind durch die Zwischenräume zwischen den Querstegen 17 gebildet und leiten durch die Längsluftleitkanäle 19 strömende Luft zu der in Fig. 1 unteren Seite des Ventilationsschichtmaterials. Feuchtigkeit, die sich unterhalb oder oberhalb des Ventilationsschichtmaterials bildet, kann über die Querluftleitkanäle 21 oder 23 und die Längsluftleitkanäle 19 abgeführt werden.1 shows an exemplary embodiment of a ventilation layer material in a schematic, greatly enlarged manner. In this case, three delta-shaped
Fig. 2 zeigt in schematischer Darstellung einen Schuh in Vorderansicht, von dem der vordere Teil weggeschnitten ist, so daß eine Querschnittsdarstellung möglich ist. Die Dicken der einzelnen Schichten sind nicht maßstabsgerecht gezeichnet.Fig. 2 shows a schematic representation of a shoe in front view, from which the front part is cut away, so that a cross-sectional view is possible. The thicknesses of the individual layers are not drawn to scale.
Der in Fig. 2 gezeigte Schuh 30 weist einen Schaft 32 auf, der auf eine hier nicht dargestellte Weise mit einer Brandsohle 33 verbunden ist. An die Unterseite der Brandsohle ist eine Laufsohle 35 angespritzt, deren Seitenteile den Befestigungsbereich zwischen Schaft 32 und Brandsohle 33 abdichtet. Die Innenseiten von Schaft 32 und Brandsohle 33 sind mit einem Ventilationsschichtmaterial 3 ausgekleidet, das seinerseits mit einer Innenschicht 37 ausgekleidet ist. Bei der Innenschicht handelt es sich um eine wasserdichte, wasserdampfdurchlässige Funktionsschicht bekannter Art. Die Innenschicht kann auch aus einem Laminat bestehen, das eine Funktionsschicht aufweist, die auf der Innenseite mit einem Futter ausgekleidet ist. Das Laminat kann auf seiner zum Ventilationsschichtmaterial 3 weisenden Seite zusätzlich mit einer Schutzschicht für die Funktionsschicht versehen sein.The
Besteht der Schaft 32 aus Leder, besteht zwar eine gewisse Wasserdampfdurchlässigkeit, so daß im Schuh gebildete Fußfeuchtigkeit durch die Funktionsschicht und den Lederschaft hindurch nach außen gelangen könnte. Insbesondere wenn der Lederschaft naß geworden ist, ist die Fähigkeit des Lederschaftes, Fußfeuchtigkeit von innen nach außen durchzulassen, nur sehr begrenzt. Die aus dem Schuhinnenraum auf die Außenseite der Funktionsschicht gelangte Fußfeuchtigkeit kann über das Ventilationsschichtmaterial 3 abgeführt werden. Dabei ist das Ventilationsschichtmaterial 3 so orientiert, daß seine Längsluftleitkanäle 19 zum oberen Schaftende gerichtet sind, so daß Außenluft zugeführt und Feuchtigkeit nach außen abgeführt werden können.If the
Die Erfindung ist besonders vorteilhaft, wenn der Schaft 32 nicht aus schwach luftdurchlässigem Material besteht, sondern aus luftundurchlässigem Material, wie beispielsweise Gummi oder Kunststoff. In diesem Fall besteht keinerlei Ableitfähigkeit für die sich im Inneren des Schuhs bildende Fußfeuchtigkeit. Hier macht sich die Ventilationswirkung des Ventilationsschichtmaterials 3 besonders vorteilhaft bemerkbar.The invention is particularly advantageous if the
Selbstverständlich ist die Erfindung unabhängig davon anwendbar und vorteilhaft, ob es sich, wie in Fig. 2 dargestellt, um einen Schuh mit Schnürverschluß handelt oder nicht.Of course, the invention is applicable and advantageous regardless of whether or not it is a shoe with a lace closure, as shown in FIG. 2.
Fig. 3 zeigt schematisch ein Beispiel eines Schuhs, der nur teilweise mit Ventilationsschichtmaterial 3 ausgekleidet ist, nämlich im Bereich einer Zunge 39. Das Ventilationsschichtmaterial 3 ist auf der Innenseite der Zunge 39 angeordnet, auf deren innenseitiger Oberfläche sich wieder eine Innenschicht 37 befindet. Diese weist wieder eine Funktionsschicht auf.3 schematically shows an example of a shoe which is only partially lined with
Im Fall der Ausführungsform nach Fig. 3 ist das Ventilationsschichtmaterial 3 wieder so orientiert, daß die Längsluftleitkanäle zum oberen, freien Ende der Zunge führen und auf diese Weise einen Luftaustausch zwischen dem Schuhinnenraum im Bereich der Zunge und dem Außenraum bilden.In the case of the embodiment according to FIG. 3, the
Es besteht noch die weitere, nicht dargestellte Möglichkeit, nicht den gesamten Schuh mit Ventilationsschichtmaterial auszukleiden, sondern nur die Innenseite der Zunge 39, und zusätzlich eine Einlegesohle vorzusehen, die Ventilationsschichtmaterial aufweist. Dabei wird das auf der Einlegesohle und das auf der Innenseite der Zunge 39 angeordnete Ventilationsschichtmaterial einstückig ausgebildet, damit von der Einlegesohle Längsluftleitkanäle bis ins Freie gebildet werden.There is still the further possibility, not shown, not the entire shoe with ventilation layer material to line, but only the inside of the
In allen Fällen wirkt die Bewegung des Schuhs beim Gehen für die Ventilationswirkung förderlich, da durch die Gehbewegungen im Schuh eine Pumpwirkung auftritt, durch welche verstärkt Luft zum Fuß hin und von dort abgeleitet wird.In all cases, the movement of the shoe when walking is conducive to the ventilation effect, since the walking movements cause a pumping effect in the shoe, through which air is increasingly discharged to and from the foot.
In allen Fällen sind die Querluftleitkanäle 21 und/oder 23 so ausgebildet, daß sie sich einen Endes zum Fuß hin öffnen und andererseits mit Längsluftleitkanälen 19 in Verbindung stehen, so daß eine Ventilationsverbindung zwischen Fußoberfläche und dem Luftraum außerhalb des Schuhs entsteht.In all cases, the transverse air guide channels 21 and / or 23 are designed such that they open at one end towards the foot and on the other hand are connected to longitudinal
