Abstract

A shock-absorbing, air-pumping, vapour-permeable, waterproof shoe comprising a shoe insert, a shoe upper part, an insole and a shoe sole is presented, or such a sole for such a shoe. Many applications devoted to the aspects of 'shock absorption' and 'breathing' of a shoe have become known. While the shock absorption is intended to relieve a person's spinal column of stress, and protect it from being damaged, when the foot makes impact, the breathing shoe prevents the formation of moisture and water inside the shoe on the basis of transpiration by circulation and transportation of moisture to the outside. The innovation is used both in the case of the sole, insole and in the case of an insert sole of a shoe. These properties are essentially achieved by layering of different materials in the region of the sole and of the upper shoe, the materials acting with differing functionality as their shaping differs. Layering with semipermeable materials, for example, achieves the effect that moisture and/or water escapes through the layer on one side, but the ingress of moisture and water in the reverse direction is prevented. Shoes in which correct transpiration is ensured on the basis of an effective exchange of heat and water vapour between the space inside the shoe and the space outside have long been known. However, these shoes at the same time lack the required waterproofness with respect to the ingress of moisture/water from the outside. In the case of the shoe presented, the region of the sole and the region of the shoe upper part are made such that they are completely impermeable to dirt, dust and water from the outside. The final multilayered semipermeable shoe insert, enclosing the shoe upper part, ensures the breathing of the shock-absorbing and air-pumping inner shoe. There are no air outlet holes or slits in the region of the sole or the region of the sides of the shoe that may become filled and clogged with dirt and dust from the outside - even together with water - by the effect of suction after the impact of the foot causes air to be expelled, and as a result become inactive in terms of breathing. The air-pumping insole serves at the same time as a shock absorber.

Patent application

Shock absorbing pumping vapor permeable waterproof shoe or such sole for shoe

description

The invention relates to the provision of a shock-absorbing air-pumping vapor-permeable waterproof shoe made of shoe insert, shoe upper, insole and shoe sole or such a sole for such a shoe.

In the prior art, a variety of applications have become known, which are dedicated to the topics 'shock absorption ^' and ^' breathing ^' in the shoe. While the shock absorption on the foot should relieve the human spine and protect it from damage, the breathable shoe prevents moisture and water inside the shoe due to transpiration by circulation and transport of moisture to the outside. Application finds the novelty both in the sole, insole and insole as the insole of a shoe.

These properties are achieved essentially by layering different materials in the region of the sole and the upper shoe, wherein the materials perform different functionality with different shapes. By layering with semi-permeable materials, it is achieved, for example, that moisture and / or water escapes on one side through the layer, but prevents the ingress of moisture and water in the reverse direction.

For a long time, shoes have been known in which proper transpiration is ensured due to the effective exchange of heat and water vapor between the interior of the shoe and the exterior. However, these shoes lack at the same time the required waterproofness with respect to the penetration of moisture / water from the outside. The tread of this shoe comprises perforated material, the inside of which is closed by a semipermeable membrane, i. Steam passage to the outside, moisture barrier to the inside, but only from intermediate layer of membrane, which forms no outsole.

Furthermore, shoes have been designed which contain a semipermeable membrane between layers of protective material and / or fillers. Frequently, such fitted shoes have insufficient air circulation because the sole surface covered by the perforations is only a small part of the entire sole surface. Air / water permeable perforations in the tread or outsole must be limited in number and diameter to prevent penetration of sharp objects into the tread or sole and the associated destruction of the semi-permeable membrane.

Within the sole-layer arrangement, the semi-permeable membrane is constantly exposed to the stresses of the body weight over the foot and claimed in any direction, whereby damage can not be ruled out. A damaged membrane results in reduced air circulation, which limits the moisture exchange from inside to outside - transpiration.

In the following, the state of the art related to shoes or shoe soles with shock-absorbing and / or breathable properties will be appreciated.

German patent specification DE 699 13 964 / European patent EP 1 089 642 / international application WO1999 / 66 81 discloses a vapor-permeable and waterproof sole for shoes. The sole is constructed in two layers; the lower sole incorporates the outsole / surface and terminates upwardly with a channeled edge forming a ventilated cavity within the skirt which also includes posts corresponding to the height of the edge. The resulting sole consists of a border in the toe and instep area, matching the insole section. Within the border, the sole is 3-ply; Starting from the foot, a vapor-permeable and / or perforated filling layer begins, followed by a membrane layer acting like a valve, which terminates with a preferably textile protective layer. Shoe and foot moisture from above is directed via the membrane into the channeled air space, which also represents the pressure and vacuum chamber for the ^' foot pump ^' .

Since the cavity has unimpeded access to the outside and thus in addition to air sucks in a dirt / water mixture that settles in the cavity - and thus in the textile protective layer and the membrane - the vapor permeability and / or water resistance of the sole will be permanently damaged ,

German Patent DE 698 18 188 / European Patent EP 910 964 discloses a vapor permeable shoe with ventilation constructed as follows. A tread has dome-shaped bulges, which continue inside as air chambers and in the middle of a small passage slot opens. Above the chambers forms a protective layer, a waterproof and vapor-permeable membrane and an overlying perforated vapor-permeable insole the conclusion of the liner. When foot pressure on the insole air / moisture is forced out of the air chambers on the open passage slots to the outside; when relief air / moisture is sucked from the inner boot on the insole and the membrane in the air chambers.

In a further embodiment, the air chambers are closed above through perforated intermediate element. In yet another embodiment sandwiched between the insole and intermediate element a membrane and a protective layer.

It can hardly be prevented that discharge of the sole through the foot passes through the closing passage slots dirt and water from the outside into the air chambers as always formed.

German patent application DE 698 16 614 / European patent application EP 983 006 / international application WO1998 / 51 177 describes a vapor-permeable footwear such that a vapor-permeable upper part with perforated insole is closed at the bottom by a molded-on perforated outsole. Between the sole sandwich there is also a layered insert with a substantially single-sided vapor permeable membrane surrounded by protective and / or apertured protective layers of substantially vapor / moisture permeable materials such as e.g. Felt or similar The aim of the structure of the footwear is to prevent formation of foot sweat and to transport it to the outside. Allen given embodiments has in common that they have outward openings to the outsole and that dirt and water can get into the insert through these openings. How the moisture comes out of the inner shoe, is not executed.

German Patent DE 695 15 291 / European Patent EP 732 067 discloses a molded shoe sole which can take air from the inside of the shoe and push it out at the heel. The sole is able to suck in air from the inside of the shoe and to deliver it to the outside by means of a ventilation channel which extends along the sole, has a one-way valve on the inlet side and ends at an air outlet hole arranged at the heel. In the front region of the sole there is a cushion from a combination of holes / grooves, which, arranged on the bottom of the sole, by elastic deformation, a suction and pressure effect - similar to an air pump - exerts such that air sucked from the shoe interior and through the ventilation duct is given to the outside without the outside air is sucked into the shoe interior.

About shock-absorbing properties of the shoe, no statements are made; adversely affects the penetration of water through the paragraph air vent hole in the interior of the shoe sole. The expression of the grooves and holes of the pillow do not correspond to the shape of an air pump of conventional design.

German patent application DE 601 01 648 / European patent application EP 1 164 883 / international application WO2001 / 56419 describes a waterproof and vapor-permeable sole for shoes with the aim of improving the water vapor permeability of a sole made of leather or a similar material. Seen from the insole, a membrane is embedded in protective vapor-permeable layers within the sole, wherein below the membrane in the tread inserts are incorporated distributed, which have venting passage openings. Moisture from the liner should pass through the membrane and the vapor-permeable layers and through-holes to the outside. The capillary causes water in the narrow passages connected with dirt in the felt, jersey, nonwoven fabric, oa formed protective layers rise and can enforce these over time.

The German Utility Model DE 295 09 366 discloses a shoe sole for receiving a ventilating outsole, achieved by the fact that the outsole has holes and at its boundary crescent-shaped cutouts and the underlying rubber or plastic sole has a studded surface and an elongated nub penroom in the there is a spring clip; the operation of the overall arrangement should correspond to that of a foot pump for air mattresses. The perforated outsole has no semipermeable openings, also covers the foot of the wearer not all holes of the perforated outsole, so that the desired circulation is absent, there is no pumping (suction and pressure) effect.

The German Utility Model DE 90 00421 presents a shoe sole for comfort shoes with shock-absorbing heel, wherein in the paragraph section of the sole body slightly above the heel spot a molded part - with multiple fixing holes and slightly conical cavities above this - is stored in soft elastic foam.

For the purpose of tool positioning the molding is made of soft elastic foam with receiving holes, adversely affects that the remaining webs between the cavities should permanently act as shock absorbers.

The utility model DE 89 11 248 describes a moisture absorbing and donating shoe sole such that the shoe sole consists of several layers, such as outsole, midsole of moisture-storing material and a moisture-permeable insole, the midsole when wearing the shoe absorbs sweat, which after wearing again is delivered. An improvement of transpiration is achieved by arranging an air-permeable, moisture-permeable cork footbed between the insole and the midsole. In order to improve the damping properties of the shoe sole, a damping sole made of polyurethane is disposed between the outsole and the midsole, which also has enforcements that continue over the outsole and act to a particular extent joint stabilizing. It is hard to see how the cork footbed of the midsole works as a water supply and release storage. No information is given about the damping properties of the enforcements.

The German disclosure DE 39 42 777 describes a shoe sole with ventilation device such that the sole identifies a longitudinally extending, provided with valves air duct, which ends in the heel area in a cavity with openings and toe area in openings. A pumping action results in which the heel compresses the air in the cavity and pushes through the valved air channel in the toe area and can flow out there, since the foot load is on the heel. Does the load on the sole change when walking from the To the toe area, the toe area is loaded and the openings closed, while the heel area is relieved and air flows into the cavity.

It lacks a statement about the structure of acting as a pump gill-like cavity in the heel region of the sole and how the spring effect can be made long term. Disadvantages are air intake openings in the sole area, since the ingress of dirt and water can not be prevented.

In the utility model DE 17 36 039 a shoe sole made of rubber or plastic with fußbelüftender effect is proposed such that draw in a midsole longitudinal grooves of the heel to toe area and complete in the heel by suction and in the toe area through air holes. The pumping action is as described above; By rolling the foot from the heel to the sole, the air sucked in at the heel pushes the toe. The heel has highly resilient walls, e.g. are designed as accordion and the air-sucking cavity of the paragraph is formed by highly resilient, air-receptive foam.

From the application it is not clear how the foam-filled cavity conducts its compressed air into the air passages formed by longitudinal grooves.

The European application EP 1 563 750 presents a breathing sole construction for footwear consisting essentially of an outsole provided with cylindrical holes in the metatarsal region, a two-part membrane system comprising a water-repellent and a receiving membrane with micropores and an insole also provided with cylindrical holes , The water-repellent membrane is an outward-acting valve that brings the foot air over the insole and the water-absorbing membrane to the outside. The water-absorbing membrane is designed to absorb and store the moisture of the foot over the insole.

The disadvantage is on the one hand, that the water-absorbent membrane is drained only after removal of the shoe and on the other hand that dirt and water penetrates through the holes of the outsole in the same and the micropores of the water-repellent membrane.

The European application EP 1 551 244 / international application WO2004 / 45 05 presents a waterproof and vapor-permeable sole for shoes, wherein the construction of the midsole over the perforated outsole consists of the layers of thermal adhesive, supporting mesh membrane and vapor-permeable protective layer. The midsole can also be prefabricated as a component.

Since here too the outsole is provided with through-holes and the capillary action pulls dirt and / or water into the vapor-permeable protective layer, clogging of the midsole is to be expected.

European application EP 1 551 243 / international application WO2004 / 34830 describes a waterproof and vapor-permeable sole for shoes and their production method. The sandwich sole consists of one on the outsole Membrane fixed with adhesive dots, the border of which is screen-printed on the outsole.

European application EP 1 545 253 / international application WO2004 / 28284 describes a waterproof and vapor-permeable sole for shoes and shoes which are manufactured with such a sole. The registration consists of several parts. First, a shoe is presented, the outsole is partially made of plastic material in the toe, middle and heel area and the rest of macroperforation, composed of mesh, felt or similar diffuse perforated material. In the macroperforation area, there are several layers consisting of transverse carrier material, a layer of macroportion (similar to macroperforation material), if necessary a layer of film material, a vapor permeable membrane layer and a fine mesh layer of synthetic material or leather. The interior moisture of the shoe is dissipated to the outside via the membrane and the macroperforation sole sections. Another variant discloses that the shoe is internally constructed with a perforated shock-absorbing foot-conforming insole, a midsole macroportion, another layer of diffused perforated EVA (ethylene-vinyl acetate) polymer followed by the above-mentioned embedded membrane layers. wherein the outsole consists of a circumferential sole and nubs protruding from a Makroperforationsschicht. Moisture can only be removed from the inner liner via the membrane and the diffuse macro layers. Here, the macro layers suck like a sponge full, even from the ambient moisture of the shoe.

The European application EP 1 506 723 discloses a breathing shoe with a total of 5 embodiments, which relate essentially to the structure of the insole and the packaging of the membrane layer, characterized in that the insole has through holes, that over the membrane, a support grid is arranged, that the outsole 2-ply constructed by a protective layer is separated, that the insole consists of leather and lining or that between insole and membrane a perforated filling layer, such as made of felt, is arranged. All publications reached the disadvantage that the Schuhinnenfeuchte is passed through the membrane either via vertical or lateral through holes in the outsole to the outside and that conversely outside moisture and / or dirt particles from the outside reach the inside of the shoe and, if necessary, lead to blockage of the insole

European patent application EP 1 417 901 describes the elastic sole of a shoe which is provided on the heel and toe with cylindrical or elliptical inserts. The insoles have hollow borders and should act shock-absorbing on the foot when applied. Another application provides that the deposits are perforated in the vertical direction.

The cushioning on the foot acts only in the small area of the sole insoles, as material-specific sole material is used around them. The holes of the inserts form capillaries for receiving dirt and / or water. European application EP 1 369 048 shows shoes with permeable and breathing upper leather which also partially cover an impermeable sole which is made breathing. This is the shoe type moccasin with circumferential upper and lower leather, which has through holes at the points of a nubian midsole. Above the midsole is a breathable perforated protective layer of felt or gelled rubber, over which is the breathing perforated insole.

The nubs have in the toe and metatarsal through holes, which should cause the breathing of the liner, but also bring by their capillary dirt and moisture in the midsole.

European application EP 1 347 691 / international application WO2002 / 52970 describes a waterproof breathable sole for shoes and a manufacturing method therefor. On a sole of leather or similar breathing and water permeable material, such as e.g. Leather or open-pore synthetic material, a membrane layer in the form of a semi-permeable film is applied, which is sealed at the edges.

European application EP 1 326 503 / international application WO2002 / 32246 discloses the construction of a midsole of a waterproof breathing sole for shoes. The embedded in the outsole midsole consists essentially of three layers, a semi-permeable membrane, an underlying protective layer and including a breathing stretchable layer of a fiber material; This last layer can also be executed like a wickerwork. The outsole has through holes, which are omitted in the last embodiment because of the breathability of the material.

The outgoing through holes in the outsole not only release moisture from the shoe interior, but they also attract moisture - and thus dirt - due to the capillarity; the latter design therefore acts like a sponge.

The European application EP 1 312 275 describes a vapor-permeable footwear consisting of a vapor-permeable upper part with connected vapor-permeable or perforated insole, which has through-holes, with underlying vapor-permeable or perforated filling layer, a downwardly adjoining watertight, vapor-permeable membrane and a permeable to heat and moisture Layer as upper and a tough waterproof layer as lower outsole. Insole, filling layer and membrane are sealed towards the edge. The inside moisture of the shoe should escape via insole, filling layer and membrane on the outer edges of the upper outsole. However, due to the pump-like loading of the insole of the shoe, moisture will also penetrate into the moisture-permeable upper outsole.

The application EP 1 201 143 discloses a breathable and waterproof shoe sole consisting of a waterproof tread with overlying interconnected chambers, which is closed by an upper perforated insole. The partitions of the chambers form the lateral conclusion to the shoe edge and are covered with a membrane permeable on one side and an overlying breathable or perforated protective element. Another variant shows the chambers only in the heel area of the shoe. The outer protective element and the membrane underneath are on the one hand permanently exposed to the effects of dirt and / or water and offer no protection against the penetration of sharp / pointed objects. A pumping action in the chambers, pressure and suction, by the foot load is not recognizable, especially not in the models where the chambers are only in the heel area.

The European application EP 1 197 158 deals with a waterproof shoe with a sole or a midsole connected to the upper leather. The connection between the upper with lining and the insole with insert is made by a 2-ply connecting element of different materials with different melting points. The insole positioned below the insole consists of the breathable filling layer, the membrane, a protective layer and the outsole with through holes.

The capillary action of the widening in the lower area through holes of the outsole will draw moisture and dirt in the multilayer insert and enforce this if necessary.

The European application EP 1 185 183 / international application WO2001 / 78 542 ^' Method of manufacturing a breathing shoe ^' shows clear substantive agreement with the above-mentioned European application EP 1 506 723.

Patent EP1 159 884 likewise presents a shoe bottom which is divided into air chambers - toe and midfoot region - and an air space - heel area - consisting of running and perforated insole, the chambers being connected to one another by an air channel. Paragraph-air space and air chambers connects an inclined air valve. In addition, the air space contains holes occupied with valves, which if necessary suck the outside air into the air chamber. The air valve can also be formed by a diaphragm.

Again, the outwardly facing valve holes will not prevent the ingress of dirt and / or water; it is possibly sucked directly and also pumped through the slanted valve from the air space in the front air chambers. The heel-air space covered by the insole acts on foot loading and unloading like the bellows of a pump, especially since no support for the foot heel load is provided.

The European application EP 1 135 039 discloses a waterproof and moisture-permeable shoe and method for its production such that in addition to the known shoe / sole structures - of the insole on the insole, a shock-absorbing vapor-permeable liner, a membrane protected by a protective film and a perforated Outsole - special protection is claimed on the construction and processing of the sealed and sewn edge in various embodiments. All embodiments have a perforated outsole provided with through holes, through whose capillary moisture and dirt rises and negatively affected the steam outlet.

The European application EP 1 093 730 describes a shoe sole with inner elastic frame of at least one bellows with at least two folds and immediate recovery after compression of the bellows, wherein the equipment of the shoe with bellows depends on the type of medical application. The bellows are always connected via a piece of pipe with a pneumatic valve positioned on the shoe edge, which closes by the internal pressure of the bellows. If only one bellow is used in the heel / heel area, a cushion effect is achieved or the use of the shoe as a slipper.

Adjustment of the sole / bellows to the spatial foot contour is carried out by actuation of the valve of a bellows under the respective foot load; about the refilling of air in the bellows are made no statements.

The European patent EP 975 243 presents a vapor-permeable shoe sole, which prevents the ingress of liquids from the outside, characterized in that the sole is provided at defined locations with pipe valves, each containing a membrane and a check valve, which the inside of the Connect shoe with its outside. The inside of the shoe has a perforated insole, including the diaphragm valves are located with a concave to the fixed insole and below the same have a cavity or a chamber which communicates through its underside with the tread surface forming the outside. If the internal pressure is greater than the external pressure, the diaphragm valves open; only at back pressure over the outsole - i. on appearance - closes the membrane.

It is not yet clear that the pumping action of the diaphragm valves should not get any moisture from outside to inside.

In the European patent EP 884 005 a shoe sole with padding element is described which pull through in the shoe longitudinal direction parallel air-conducting channels, which are in communication with the perforated insole. These air ducts continue in the heel and end in an evacuation chamber communicating via a breathing hole valve in the heel with the outside air under the sole. When pressure is applied to the insole by the foot, air is forced through the longitudinal channels into the evacuation chamber and the breathing hole in the heel. When the sole is relieved by the foot, negative pressure is created in the evacuation chamber.

Since the foot does not rest homogeneously on the insole and thus not all holes of the insole are closed, it can not be seen that no compressed air escapes through the insole. Furthermore, it is not apparent that no external moisture enters the shoe.

European Patent EP 797 937 discloses a shoe sole with a deformable arch and a shoe with such a sole. This is the sole of a sports shoe, which has a vault and a stiffening contains element. The reduction in the height range of the arch causes the front sole region to pivot outward; conversely, increasing the height range causes the sole region to pivot inward. The pivoting of the sole region causes shock-absorbing effects on the wearer of the shoe; Aeration and / or ventilation of the shoe is not treated.

The European patent EP 751 722 describes a shoe sole with a damping bellows as boundary. The multiple sealed and fluid-filled chambers of the sole act as air cushion and thus as a damping bellows in the corresponding shoe, where this bellows is used. The shoe certainly has shock absorbing properties, but vapor permeability of the shoe is not provided.

European Patent Specification EP 336 801 discloses a shoe sole or insole with built-in fluid circulation which forms in chambers of the lower sole which also contains inclined transverse lamellae so that the entire sole is shock-absorbing. A circulation over the inner and outer shoe is not provided.

A shoe sole with a soles massaging and ventilating insole presents the European patent EP 289 985. Shown is an on the outsole constructive insole, the groove-forming - transverse to the shoe longitudinal extent - is interspersed by each application different ribs. The rib heads point upwards. The upper end of the sole forms a perforated cover. The groove / rib construction of the sole is designed to absorb impact and at the same time to pump air through the perforation by bending and re-erecting. An arrangement with the rib heads pointing downwards is also provided.

The disadvantage is the moisture and dirt accumulation in the grooves between the ribs; The air will escape through the foot pressure in some places, however, the construction does not prevent the absorption of moisture and dirt in relief of the sole by the foot.

European Patent EP 268 661 discloses a composite shoe sole having a toe, an instep and a heel area. The peculiarity of the shoe sole lies in the very different structure of the three sole areas, which have properties in itself to offer the always correct sole constellation for the most varied foot and body construction of the wearer. The sole construction certainly has impact-reducing properties for the respective wearer; foot, sole or shoe ventilation measures are not provided.

International application WO2005 / 70658 discloses a shoe with a vapor permeable and waterproof sole and upper. While the sole construction is similar to the known sandwich construction with perforated through holes provided with outsole, the upper shoe is also made of layered materials. The outer vapor permeable upper leather closes inside one vapor-permeable and waterproof membrane film and a lining, which must also be vapor-permeable.

Reference is made, as above, to the capillary action of the perforated sole.

In the international application WO2005 / 63,070 a waterproof vapor-permeable multilayer - two-layered product is presented. While the first layer is vapor permeable, microporous, and partially hydroscopic, or may assume long term hydroscopic properties, the second layer is vapor permeable and water resistant.

No comments are made on the use of the shoe development assembly.

The international application WO2005 / 63,069 presents a vapor-permeable waterproof sole for shoes whose multi-ply consists of an insole - it must be permeable to vapor, a vapor-permeable midsole and a perforated sole plane provided with through-holes, which forms the connection to the outsole. Regarding the tightness special precautions are taken at the edges.

About the structure of the outsole and the related penetration of moisture and dirt, there is no comment.

In the international application WO2005 / 11 417 a vapor-permeable and waterproof sole for shoes, but not only for open shoes - such as sandals, etc. - is presented. A total of 7 layers of soles are presented: from the vapor permeable and perforated insole to a comfort sole with a circulation air gap, an open area midsole for shock absorption, a through hole midsole, a vapor permeable but waterproof membrane covered by a moisture permeable protective layer is completed by the perforated outsole provided.

A disadvantage also affects the dirt and moisture attracting capillary action of the through holes of the outsole on the clogging of the midsole.

All publications presented are only partially or not at all suitable for specific use as a shock-absorbing pumping vapor-permeable waterproof shoe or as such sole for such shoes.

The invention is therefore based on the object to provide a device according to the preamble of claim 1 for universal use as possible, to improve the above disadvantages, to reduce the variety of possible designs and thus to simplify the production and storage.

This object is achieved by a shoe or a sole for such a shoe of the type mentioned above with the characterizing features of claim 1 solved. Advantageous embodiments, the figure shows and take the dependent claims.

The achieved advantage of the shock-absorbing air-pumping vapor-permeable waterproof shoe shoe insert, shoe upper, insole and shoe sole or such a sole for such a shoe, on the one hand by the one-piece, the outside completely between fire / inner sole and shoe sole sealing mating shoe upper and on the other hand by the preferably one-piece, multi-layered design of the fire / inner sole with the downwardly widening hemispherical mutually insulated air chambers with through holes for fire / insole, the shock absorption at foot load shock-reducing and pumping work and in the liner cause an air circulation, given.

The presented invention is sufficient for the advantage over the applications presented above that the sole and the shoe upper part are designed to be completely dirt, dust and waterproof to the outside.

The shoe upper comprehensive final multi-layer semipermeable shoe insert ensures the breathing of the shock-absorbing and air-pumping liner. There are no air outlet holes or slots in the sole or shoe side area, which may become saturated and clogged with external dirt and external dust, even when combined with water, after the air outlet caused by the footwell, thereby becoming breathable.

The application of the invention is suitable for all shoe shapes; It is therefore extremely broad and design-neutral - for everyday use shoe and as for the sports shoe, etc. The breathable shock-absorbing sole allows air circulation in the footwell / liner; The sole with the sole construction according to the invention is also manufacturable and universally usable as an insole.

The manufacturability of the breathable shock absorbing shoe / sole with industry-standard technologies, equipment and facilities, facilities and tools is given. The manufacturing costs of shoes according to the invention are comparable to today's shoe costs.

A preferred embodiment of the subject invention is illustrated in the figures and will be explained in more detail below. It shows

Fig. 1 shows a three-dimensional structure of a portion of the shock-absorbing air-pumping vapor-permeable waterproof shoe or sole for shoes, left side in unloaded and right side in loaded representation.

Fig. 2 shows a plan view of the layers of the fire / insole Fig. 3 shows a bottom view of the layers of the fire / insole. The same and equivalent components of the embodiments are always provided in the figures with the same reference numerals.

The description of the device according to the invention will be continued with reference to the explanations of the figures.

As can be seen from the exemplary embodiment, FIG. 1, the shoe structure consists of the multi-layer, semi-permeable shoe insert 2, the continuously sealing shoe upper 3, the multi-layered foot-active insole 4 and the shoe sole 5. The structures can preferably be made in one piece.

The shoe concept provides that the air of the air chambers 46 of the central layer 42 of the fire / insole is compressed under load from the foot, but that because of the tightness of the insulated air chambers arranged the fire / insole works as a shock absorber, which is beneficial to the Relief of the spine affects. In this case, only the air chambers shock absorbing and shock absorbing, the air ducts 45 of the middle layer and - in extension with - their flush through holes 44 of the top layer 41 are closed by the foot load, s.a. Fig. 1, loaded and unloaded representation. Only poorly closed air chambers have a spring effect due to the initially built, but gradually escaping air pressure.

The deeper consideration of the figures it is found that the entire footwear is constructed moisture repellent. The sealing shoe upper 3 forms an absolutely watertight trough, which is completed below by the shoe sole 5. In the area above the shoe sole is the multi-layered fire / insole 4, which consists of the layers

- footwear upper 41,

- Elastic mid-layer 42 with hemispherical insulated air chambers 46 and air duct 45 and

- Pad 43, which is airtight welded or glued to the middle layer.

The through holes 44 of the top layer are centrally connected to the air channels and the air chambers of the middle layer. If the fire / insole is loaded by the foot, see Fig. 1, loaded and unloaded representation, the air is compressed in the air chambers of the sealed by the foot through holes; however, the top layer will lower in its overall surface due to pressure. From the through holes not closed by the foot / air ducts / air chambers air under pressure - and with firmly laced shoe - through the multi-layered semi-permeable shoe insert 2 escape. When depressurized by the foot, the total surface of the top layer will rise and thus the compressed air chambers will regress through air intake. Due to pressure changes, the fire / insole works like a foot-controlled air pump; Air pressure and suction alternate, aerate the foot and prevent the onset of perspiration. Fig. 2 shows a plan view of the layers of the fire / insole in the order foot-active upper layer 41, breathing elastic middle layer 42 and the airtightly welded or bonded to the middle layer pad 43rd

Clearly the through holes 44 of the top layer are shown. The middle layer contains on the one hand the air channels 45 and the hemispherical recesses which form the air chambers 46 with the smooth bonded or welded base. The layers are welded flush with each other to form a fire / insole, so that the air chambers with the air channels and - in extension - flush with the through holes in loading and unloading for air circulation in the footwell / liner provide.

Fig. 3 shows a bottom view of the layers of the fire / insole in the order pad 43, middle layer 42 and top 41th

A further embodiment of the invention provides that the multi-layered semi-permeable shoe insert is firmly connected at its edges to the foot opening sealingly connected to the shoe upper and makes the air exchange between the air circulation of the footwell / liner and the outside air.

Another embodiment of the inventive novelty is given by the fact that the preferably one-piece sealing shoe upper is trough-shaped and forms the footwell or liner with the shoe insert and the fire / insole.

According to a further embodiment of the invention, the spatial extent of the air chambers of the middle layer of the fire / insole when loading and unloading the same - regardless of their geometric shape - exert a pumping action and a shock and shock absorbing effect, which on the one hand reduces the Fußtranspiration and on the other hand relieves the spine. The footrest / foot pad is given by the sandwich-like construction of fire / insole, shoe upper and shoe sole.

A further embodiment of the invention provides that the footwell / inner shoe is partially or fully equipped with an additional air-permeable textile, leather or nonwoven layer, which serves exclusively comfort.

Another embodiment of the inventive novelty is given by the fact that the production of the fire / insole is done by the correct position hole-solid bonding several prepared material layers and that the production of multi-layer semipermeable shoe insert by the correct position solid bonding several prepared layers of material.

Advantageous developments of the invention are the subject of the dependent claims. The numerous possibilities and advantages of the embodiment of the invention are reflected in the number of property rights claims. LIST OF REFERENCE NUMBERS
