Abstract

Water-vapor permeable and water-permeable sole unit (15) for footwear (11), comprising:
at least one sole ply (25) having at least one large-area opening (27) extending through the thickness thereof;
at least two superimposed, one-piece or multi-piece sheet material, which close the at least one opening (27) and of which a first fabric has a textile water vapor permeable barrier layer (39) and a second sheet has a water vapor permeable decorative layer (45) below the first sheet is arranged at least in the region of at least one opening (27) and from the bottom of the sole layer (25) in the at least one opening (27) is visible.

Description

  • Footwear with a waterproof and water vapor permeable shaft has been available for a long time, so that such a footwear, despite being waterproof, can now give off sweat moisture in the shaft area. So that even in the sole region sweat moisture can escape, it has gone over to a sole structure, which has an outsole with through-thickness extending through openings and above a waterproof and water vapor permeable sole functional layer, for example in the form of a membrane. An example shows the EP 0 382 904 A2 whose outsole has passage openings in the form of microperforations, with a corresponding limitation of the water vapor permeability.
  • In order to get in view of the strong sweating tendency of the human foot to a higher water vapor permeability, it has gone over to provide the outsole with large compared to micro perforations through holes. From the EP 0 275 644 A2 , which shows an example of this, the teaching is known to make the through holes as large as possible in order to achieve a particularly high water vapor permeability.
  • The larger the through-holes of the outsole, the greater the risk that a waterproof membrane located above the through-holes of the outsole will be damaged by foreign objects, such as pebbles, which penetrate the through-holes and thus deprived of their watertightness. Therefore, the sees EP 0 275 644 A2 that between the outsole with its through holes and the membrane above it a protective layer, for example, of a mesh or felt material is arranged, which prevents the through holes of the outsole penetrating foreign body from penetrating to the membrane.
  • Further examples with large through holes of the outsole, in which the passage openings are closed by means of a membrane against the penetration of water to Schuhinnenraum and below the membrane is a protective layer which is to prevent the penetration of foreign bodies to the membrane, are known from WO 2004/028284 A1 . WO 2006/010578 A1 . WO 2007/147421 A1 and WO 2008/003375 A1 , In all these cases, on one side of the membrane, usually a film, a textile backing is laminated in the form of a fine knit fabric. An arranged between the membrane and through holes of the outsole net-like protective layer provides some protection against the penetration of foreign bodies to the membrane. To improve the protection for the membrane, a further protective layer is arranged between the membrane and the net-like protective layer, which is, for example, a felt layer. Thus, a double protection for the membrane is created, in which two superimposed layers are involved, each of which has a technical protection function.
  • The Material selection for these layers and their thickness and Puncture resistance values are tailored to the needs of to adapt to each practical embodiment. This applies to the known solutions as well as for the solutions presented by the present invention.
  • Another example of very large sole openings shows the WO 2007/101624 A1 according to which the large passage openings of the outsole are stabilized by means of stabilizing webs and / or stabilizing gratings. These wear in the through holes fitted water vapor permeable, textile material, such as felt-like material. The shoe sole composite constructed in this way is connected to a shaft whose shaft bottom is closed with a watertight and water vapor permeable shaft bottom functional layer, so that the entire shoe is waterproof and permeable to water vapor.
  • For the textile material is particularly suitable a fiber layer, which has at least two fiber components, with respect to their melting temperatures differ, with at least a portion a first fiber component, a first melting temperature and a having underlying first softening temperature range and at least a portion of a second fiber component a second Melting temperature and an underlying second softening temperature range and the first melting temperature and the first softening temperature range higher than the second melting temperature and the second softening temperature range and wherein the fiber layer due to thermal activation of the second fiber component having a second softening temperature range lying adhesive softening temperature in a thermal manner mechanically is solidified while maintaining water vapor permeability in the thermally consolidated area. It can either the passage opening or optionally a plurality of passage openings the outsole closed with individual pieces of textile material his or all through holes of the outsole are closed with a single piece of textile material.
  • In this known footwear, the textile material has two functions. On the one hand, it serves to stabilize the sole structure, in particular in view of the fact that an outsole with large Ö itself can not sufficiently contribute to the stabilization of the sole structure. Because the textile material is formed with a relatively high inherent stability, which benefits the overall stability of the sole structure. On the other hand, in the finished footwear, for example according to WO 2007/101624 A1 , above the sole construction a waterproof, water vapor permeable membrane, which is protected by the textile material from damage by foreign bodies such as stones, which could damage the membrane.
  • For The textile material is particularly suitable polymers, for example are selected from PES (polyester), polypropylene, PA (polyamide) and Mixtures of polymers.
  • In an embodiment according to the already mentioned WO 2007/101624 A1 consists of the textile material of a fiber composite in the form of a thermally mechanically strengthened and additionally surface treatment by thermal surface treatment surface-bonded nonwoven fabric with two fiber components, which are each constructed with polyester fibers. In this case, the first fiber component with the higher melting temperature forms a carrier component of the fiber composite and forms the second fiber component with the lower melting temperature, a solidification component. In order to ensure a temperature stability of the entire fiber composite of at least 180 ° C, and in view of the fact that footwear can be exposed to relatively high temperatures during its production, for example, when molding an outsole, in the considered embodiment for both fiber components polyester fibers with a more than 180 ° C melting temperature used. There are several variations of polyester polymers that have different melting temperatures and corresponding underlying softening temperatures. In the contemplated embodiment of the felt-like material, a polyester polymer having a melting temperature of about 230 ° C is selected for the first component, while a polyester polymer having a melting temperature of about 200 ° C is selected for the second fiber component. The second fiber component may be a core-sheath fiber wherein the core of this fiber is a polyester having a softening temperature of about 230 ° C and the sheath of this fiber is polyester having an adhesive softening temperature of about 200 ° C. Such a fiber component with two fiber portions of different melting temperature is also referred to as "Bico". Further details of such textile material, which may be, for example, felt-like material, can be found in the already mentioned WO 2007/101624 A1 ,
  • The for the two purposes indicated above, namely Stabilization and membrane protection, especially suitable on thermal Way mechanically strengthened textile material has the disadvantage that its serving as solidification component fiber component with the lower melting temperature unsatisfactory or only can be stained insufficient and therefore in the fiber composite remains white, what the textile material is not a whole gives a satisfactory appearance. This is disadvantageously noticeable because the textile material through the large passage openings the outsole is visible through.
  • the growing need, the entire footwear and so too to make the bottom of his sole fashionable, also by the bottom the sole construction given a fashionable appeal is, in particular by appealing and varied color design, can therefore not be met with this textile material.
  • It is also known, large openings in a sole to close with other materials, for example with felt-like material, at least partially made of aramid fibers how KEVLAR exists. However, fibers from aramids are not or only very badly dyeable, so it is also in this Case comes to the problems already described above.
  • With The present invention is a sole unit for Footwear created, which is a satisfactory and largely any fashionable design of the bottom of the sole construction in terms of Color and patterning as well as material selection enables without the water vapor permeability of the sole unit or their barrier or protective function seriously affect.
  • Reached This is done with a sole unit according to the invention according to protection claim 1, with which inventive Footwear made according to protection claim 25 can be. Embodiments of the invention are in the dependent protection claims specified.
  • A sole unit according to the invention for footwear is permeable to water vapor and permeable to water and has at least one sole ply with at least one large opening extending through its thickness. It also has at least two superimposed sheets, which close the at least one opening and of which a first sheet has a textile moisture vapor permeable barrier layer and a second sheet has a water vapor permeable decorative layer below the first Flächengebil which is arranged at least in the region of the at least one opening and is visible from the underside of the sole layer in the at least one opening.
  • at An embodiment of the invention is the barrier layer constructed with a fiber layer, which at least two fiber components which differ in their melting temperatures, wherein at least a portion of a first fiber component is a first Melting temperature and an underlying first softening temperature range and at least a portion of a second fiber component a second melting temperature and an underlying second softening temperature range and the first melting temperature and the first softening temperature range higher than the second melting temperature and the second softening temperature range are. The fiber layer is due to thermal activation of the second Fiber component having a second softening temperature range lying adhesive softening temperature in a thermal manner mechanically solidified while maintaining water vapor permeability in the mechanically mechanically solidified area.
  • It There can be various reasons for footwear with a sole unit, in particular of the previously mentioned type, that from the bottom of the outsole through its large-area Breakthroughs, also called openings here, visible through Material of the sole unit at least partially by means of an inventive Cover decorative layer.
  • Of the use of such a decorative layer according to the invention in a sole unit with a fiber layer mentioned above is based on the knowledge that the coloring of as Hardening component serving fiber component with the lower Melting temperature requires that this fiber component on a Temperature is warmed, which is above the softening temperature This fibrous component is located so that this fiber component is not can be colored. It's different with the other fiber component with the higher melting temperature. Their melting temperature is higher than the temperature required for dyeing. One Dyeing is therefore only with regard to the fiber component with the higher melting temperature possible, but not with regard to the fiber component with the lower melting temperature, so that white flecks within the fiber composite of the textile material can not be avoided, resulting in an aesthetic unattractive appearance leads.
  • this Problem is with a sole structure with such a fiber layer inventively encountered by the fact that not Satisfactory coloring of the textile material accepted and This textile material is preceded by a decorative layer, which made of material with appealing color or coloring, for example, this material is latticed or net-like or from a perforated sheet or textile material with high water vapor permeability, the water vapor permeability the sole unit thus hardly affected by the decorative layer becomes. With the solution according to the invention can therefore, with substantially hardly impaired water vapor permeability, hide the less appealing appearance of the textile fiber layer behind the decorative layer, which is the one above related to the textile material explained limitation in terms of color or coloring not subject. The decor layer can therefore be independent and dyed according to almost any fashionable ideas and designed what the textile material of the above-mentioned fiber layer is not possible. you can selectively use materials for the decorative layer, which dye well and / or pattern or by nature have appealing colors and / or patterns.
  • With So the solution according to the invention you have a technical requirement, namely a protective function, and an aesthetic requirement, namely a visually appealing appearance, thus easier to realize bar and also commercially attractive made that these two requirements no longer trying to achieve with a single location but divided into two different layers, each one for itself targeted with regard to their specific requirement and function can be trained. On the one hand you need in the Able to no longer compromise with the technical function at least a halfway appealing aesthetic To make an impression. On the other hand, you can change the situation with the aesthetic Function as good as finally according to this Design function because it is the technical function of others Location does not need to provide.
  • It gives further commercial advantages of the invention Decoupling of technical function, eg stabilization function, and aesthetic function. The location with the technical function, for example, the stabilization layer, can be produced in standard color so that they are suitable for all shoes with one technically effective position is to be used, which is very cost effective. The location with the aesthetic Function, namely the decorative layer, can be from a standard range which is also very cost effective.
  • A decorative layer according to the invention ver may also be advantageous in the event that for both components of the thermally bonded fiber layer materials are or should be available that are not subject to the above-mentioned limitation in color or color. For example, the thermally mechanically consolidated textile material of the fiber layer is more expensive than materials that are suitable for the decorative layer. Especially in the highly fashionable market segment of casual shoes, there is a strong trend to provide the same or different shoe models with different colors and patterns, for example, to appeal to different age groups with different fashion designs. If this need were met with differently dyed or patterned fiber layers, the respective shoe manufacturer would have to get and store correspondingly dyed and / or patterned different fiber layers. This would be disadvantageous not only from a logistical point of view both for the manufacturer of the fiber layers and for the shoe manufacturer but also in terms of higher purchasing costs for the shoe manufacturer due to the relatively small number of pieces per color and / or pattern type. The fact that, when using the decorative layer, the appearance of the underside of the sole unit is no longer determined by the fiber layer material but by the appearance of the decorative layer, the shoe manufacturer can relate uniform fiber layer material and in terms of visual and fashionable appearance of the underside of the sole unit on the decorative layer focus. Material for the shoe manufacturer or, if he does not make the soles for his shoes, the sole manufacturer in targeted quantity and color as well as structure and material type or make even in terms of color and color pattern, where he from a larger number of suppliers materials for He can refer to him desired decorative layers, so that he can turn both different in terms of pricing and in terms of the availability of different materials to different materials manufacturers. Thus, irrespective of whether or not the material of the fiber layer can be dyed according to the desired ideas, it may be worth considering the optical design of the underside of the sole unit with regard to color and pattern with an additional decorative layer, in particular for the above-mentioned reasons of logistics, Diversity and under price aspects.
  • Should the material for the decorative layer after its production be colored, for example by spraying, Screen printing or the like, just needs to pay attention to become that coloring or patterning in such Way, that the stitches or other openings or Pores of the material of the decorative layer remain so open that the desired water vapor permeability obtained remains. Such a color design with such means and method would be in a textile layer, in particular Felt layer, which in known cases through the through holes of the Outsole is visible, not possible. On the one hand let on surfaces of textile materials such as felt Color samples, in particular finely structured type, not with sufficient Resolution. On the other hand can be difficult to avoid when applying paint by spraying or screen printing the surfaces of such materials in significant Measurements are added so that the desired Water vapor permeability can no longer be realized. In addition, such techniques are relatively expensive. A coining of textile materials leads to a non-uniform surface height, which in turn is disadvantageous when molding sole material, since then the flow of sole material in the textile layer unpredictable becomes.
  • A Decorative layer according to the invention is particularly advantageous in an embodiment wherein the fiber layer is two Having fiber components and for the second fiber component a material is used in which the softening temperature range the second fiber component below for dyeing the temperature required for the second fiber component. Because In this case, the aesthetically little attractive appearance of the fiber layer with its white spots only with a decoration layer according to the invention, so the bottom of the sole unit still visually appealing can be designed.
  • Especially in the case of shoes with a sole unit, provided with a decorative layer according to the invention can address to younger customers, one can with the decor layer be achieved attractive "metal look". Therefore exists in one embodiment of the invention, the decorative layer Material that brings the appearance of metal with it. In a dedicated first embodiment The invention consists of the material of the decorative layer exclusively made of metal, for example a metal grid or a metal net. In a designated second embodiment of the Invention consists of the material of the decorative layer of a metallized Plastic grid or is constructed with a metallized fiber, which are brought into a yarn structure or in the form of a yarn net is.
  • Material examples of a purely metallic decorative layer are iron, aluminum and steel. Material examples of a decorative layer of metallized plastic are woven, knitted fabric and knitted fabric with a coating of tin, silver, copper, nickel, or other alloys, eg. B.

  • When Material for the decorative layer are also suitable by Processing such as perforating water vapor permeable designed materials or perforated sheet, for example made of polyamide, polyurethane, etc., or inherently water vapor permeable Flat material, for example made of plastic, textile, leather, metal, glass fibers or a combination thereof.
  • you can the above mentioned material examples for the decorative layer also combine with each other or with other materials to the each desired color and pattern effect to achieve.
  • at an embodiment of the invention, the decorative layer a substrate and a surface covering the substrate Coating on, the coating being built up with a material which is colored or at least has a dye. In this way, different material requirements for combine a decorative layer, for example, a substrate with desired mechanical properties and desired water vapor permeability in combination with a coating which exclusively colored according to aesthetic criteria and can be patterned because they are desired or required mechanical properties and the desired water vapor permeability the decorative layer does not have to contribute.
  • In embodiments of the invention, the decorative layer can have a water vapor permeability in the range of 10,000 g / m 2 .24 h to 50,000 g / m 2 .24 h, in particular in the range of 20,000 g / m 2 .24 h to 30,000 g / m 2 .24 h, exhibit.

  • Water vapor permeable:
  • As a "water vapor permeable", a functional layer / a functional layer laminate is considered, if it has a water vapor transmission rate Ret of less than 150 m2 × Pa × W-1. The water vapor permeability is tested according to the Hohenstein skin model. This test method is used in the DIN EN 31092 (02/94) respectively. ISO 11092 (1993) described.
  • The water vapor permeability values of the barrier layer / fiber layer / stabilization layer / decorative layer according to the invention are detected by means of the so-called cup method DIN EN ISO 15496 (09/2004) tested.
  • The degree of water vapor permeability of the sole unit can be compared with that in the document EP 0 396 716 B1 determined measurement method, which has been designed to measure the water vapor permeability of an entire shoe. For measuring the water vapor permeability of only the sole unit of a shoe, the measuring method according to EP 0 396 716 B1 also be used by with the in 1 of the EP 0 396 716 B1 the measurement setup shown is measured in two successive measurement scenarios, namely once the shoe with a water vapor permeable sole unit and another time the otherwise identical shoe with a water vapor impermeable sole unit. From the difference between the two measured values, the proportion of water vapor permeability can then be determined, which is based on the water vapor permeability of the water vapor permeable sole unit.
  • For each measurement scenario, using the measurement method according to EP 0 396 716 B1 proceeded, namely with the following sequence of steps:
    • 1. Condition the shoe by leaving it in a conditioned room (23 ° C, 50% relative humidity) for at least 12 hours.
    • 2. Removal of the insole (footbed)
    • 3. lining of the shoe with adapted to the shoe interior waterproof, water vapor permeable lining material, which in the Fußeinschlüpföffnung of the shoe with a waterproof, water vapor impermeable sealing plug (for example made of Plexiglas and with an inflatable cuff) waterproof and water vapor tight sealable.
    • 4. pouring water into the lining material and closing the Fußeinschlüpföffnung the shoe with the sealing plug
    • 5. preconditioning the water-filled shoe by allowing it to rest for a predetermined period of time (3 hours) while maintaining the temperature of the water constant at 35 ° C. The climate of the surrounding area is also kept constant at 23 ° C and 50% relative humidity. During the test, the shoe is blown from the front by a ventilator with an average of at least at least 2 m / s to 3 m / s wind speed (destroying a static layer of air forming around the standing shoe, which would cause considerable resistance to the water vapor passage)
    • 6. re-weighing the seal plug-sealed, water-filled shoe after preconditioning (gives weight m2 [g])
    • 7. rest again and actual test phase of 3 hours under the same conditions as in step e)
    • 8. re-weigh the sealed, water-filled shoe (gives weight m3 [g]) after the test period of 3 hours
    • 9. Determination of the water vapor permeability of the shoe from the amount of water vapor (m2 - m3) [g] escaped through the shoe during the test time of 3 hours according to the relationship M = (m2 - m3) [g] / 3 [h]
  • After this Both measurement scenarios have been carried out in which the water vapor permeability values on the one hand for the entire shoe with water vapor permeable sole unit (value A) and on the other hand for the entire shoe with wasserdampfundurchlässigem Shaft bottom construction (value B) has measured, the water vapor permeability value for the water vapor permeable sole unit determine solely from the difference A-B.
  • Important it is during the measurement of water vapor permeability of the shoe with the water vapor permeable sole unit to avoid the shoe or its sole directly on one closed base stands. This can be done by lifting the shoe or by stopping the shoe on a grid structure, so that it is ensured that the ventilation air flow as well or completely along below the outsole can.
  • It is useful for each test setup for a given Shoe repeat measurements and averages to look at it in order to better assess the spread of the measurements to be able to. It should be with the measurement setup for each Shoe be carried out at least two measurements. At all Measurements should be of a natural variation of the measurement results of ± 0.2 g / h around the actual value z. B. 1 g / h are assumed. For this example could thus for the identical shoe measured values between 0.8 g / h and 1.2 g / h are obtained. Factors influencing these fluctuations could, for example, by the perform the test Person or of the sealant quality at the upper shank edge come. By averaging several individual readings for the same shoe can get a more accurate picture of the actual value become.
  • All Values for the water vapor permeability of the sole unit are based on a normal laced men's shoe Size 43 (French measure), this size is not standardized and Shoes from different manufacturers can turn out differently.
  • The Invention will now be described with reference to embodiments which merely non-limiting examples of the Implementation of the invention, additionally explained. In the accompanying drawings show:
  • 1 a perspective view of an embodiment of a shoe with a shaft and a composite shoe sole with an inventively designed sole unit;
  • 2 a perspective view of the shoe according to 1 wherein the composite shoe sole is not yet connected to the shoe upper;
  • 3 the composite shoe sole in accordance with 1 and 2 in a perspective plan view;
  • 4 a schematic cross-sectional view of the in 1 shown shoe in an embodiment with glued Schuhsohlenver bund in the assembly stage according to 2 wherein the shaft is not fully shown; and
  • 5 a schematic cross-sectional view according to 4 However, for an embodiment of a shoe with a molded onto the shaft shoe sole composite, wherein the shaft is also not fully shown.
  • If here terms such as top, bottom, right, left, etc. used, this is always only on the specific representation in the respective figure and is not absolute.
  • The 1 and 2 show in perspective oblique view from below an embodiment of a shoe according to the invention 11 with a shaft 13 and a sole unit according to the invention 15 , In 1 is the shoe 11 shown in a state in which the shaft 13 and the sole unit 15 connected to each other. 2 shows the shoe according to 1 in a mounting step, before the sole unit 15 on the shaft 13 is attached.
  • The shoe 11 has a forefoot area 17 , a midfoot area 19 , a heel area 21 and a Fußeinschlüpföffnung 23 on. The sole unit 15 has a sole layer in the form of a carrier layer 25 that are crucial to stabilizing the finished sole unit 15 contributes and which in the forefoot 17 and in the midfoot area 19 large openings 27 ( 2 ) having. Due to its stabilizing effect, the carrier layer becomes 25 also called stabilization layer here. Large area in this context means that the individual openings 27 have an area in the range of one to several cm 2 , for example in the range of about 2 cm 2 to about 30 cm 2 , within this range, for example in the range of 10 cm 2 to 20 cm 2 . The breakthroughs 27 are chosen as large as possible to a sole unit 15 to make available with as much water vapor permeability as possible.
  • Below the carrier layer 25 there is an outsole 29 , which is composed of several individual outsole parts, namely a outsole part 29a in the heel area, a sole part 29b in the ball of the foot and a sole part 29c in the toe area. These outsole parts are at the bottom of the carrier layer 25 attached. In the ball of the foot and in the toe area, the outsole parts show 29b and 29c large openings 27 on, which are dimensioned such that the openings 27 the carrier layer 25 remain completely or substantially free of outsole material, so that through the openings 27 the carrier layer 25 reached water vapor permeability of the sole unit is not affected.
  • In the illustrated embodiment is located above the carrier layer 25 a cushioning sole layer 31 , which causes a shock absorption and thus improves the walking comfort of the shoe. The damping sole layer 31 has a damping sole part 31a in the heel area and a cushion sole part 31b in the forefoot area. Also the damping sole parts 31a and 31b have large openings on which the openings 27 the carrier layer 25 completely or at least substantially free to the water vapor permeability, which with the openings 27 the carrier layer 25 is achieved, not or not significantly affect
  • at An embodiment of the invention may also be the sole be formed in one piece. That is, the damping position and the outsole layer are then combined into a single sole layer, with regard to impact damping properties and running properties a two properties as well as possible Material selection is made.
  • Not only the damping sole layer 31 but also the parts of the outsole 29 Made of an elastic material with a degree of softness to achieve a good walking comfort and to achieve an outsole with good treading properties. Due to this relatively soft elastic material and due to their composition of individual parts with large apertures, the outsole 29 not sufficient for the stability of the entire sole unit 15 contribute. Even in embodiments with a one-piece outsole, a sufficiently satisfactory stability of the entire sole unit can not be achieved due to the soft elastic material and the large openings.
  • Due to their relatively soft material and their large openings on the one hand and their composition of individual parts on the other hand offer again the parts of the outsole 29 nor the parts of the damping sole layer 31 the stability desired for a sole unit. For this reason, the carrier layer acting as a stabilizing layer 25 is provided, which can be made of relatively stiff material, because it does not have to take into account any pedal damping properties or Laufsohligenschaften. To the stabilization properties of the stabilization layer 25 , which, despite their relatively stiff material through the large openings 27 to some extent may be impaired to improve, are the individual breakthroughs 27 the carrier layer 25 by means of stabilizing webs 33 bridged. This preserves the carrier layer 25 a degree of bending and torsional rigidity, which is the total sole unit 15 gives the desired stabilization.
  • As in 2 is shown, the lower end of the shaft 13 with a shaft bottom 35 closed before the sole unit 15 with the shaft 13 is connected. The shaft bottom 35 is with a shaft bottom functional layer 37 provided as below in connection with the 4 and 5 will be explained. This shaft bottom functional layer 37 has, for example, a membrane which is at least waterproof, preferably also water vapor permeable.
  • While 2 the sole unit 15 in perspective oblique view from below is in 3 the sole unit 15 shown in perspective oblique view from above. As 3 shows are on the off the outsole 29 lying off the top of the carrier layer 25 in the middle area 25b and their forefoot area 25c several pieces 39a . 39b . 39c and 39d one as a fiber layer 39 trained barrier location. With these fiber pieces 39a . 39b and 39c are the in 3 invisible openings 27 the carrier layer 25 covered. In 3 are also in the heel area and forefoot area of the sole unit 15 on the top of the carrier layer 25 arranged tread damping layer parts 31a respectively. 31b to see. The tread damping section 31a in the heel area is in the embodiment shown substantially full-surface, while the tread damping portion 31b in the forefoot area with recesses where the fiber layer pieces 39b . 39c and 39d are provided. The fiber layer pieces 39a to 39d lie above the stabilizing bars 33 , in the 3 are not visible. At the in 3 embodiment shown, the carrier layer 25 boundary edges 43a . 43b and 43c on which the respective opening 27 the carrier layer 25 surrounded and which serve as enclosures for each associated fiber layer piece.
  • Because the outsole parts of the outsole 29 , the backing layer 25 and the step cushioning parts 31a and 31b different functions within the sole unit 15 have forming Schuhsohlenverbundes, they are expediently constructed with different materials. The outsole parts, which have a good abrasion resistance and should provide sure-footedness, consist for example of a suitable as outsole material thermoplastic polyurethane (TPU) or rubber. The step cushioning parts 31a and 31b , which are to cause a shock absorption in the walking movements for the user of the shoe, consist of correspondingly elastically yielding material, such as ethylene-vinyl acetate (EVA) or polyurethane (PU). The stabilization situation 25 , which is for the non-contiguous outsole parts 29a . 29b . 29c and for the likewise non-coherent footfall cushion parts 31a . 31b as a carrier and for the entire sole unit 15 serves as a stabilizing element and should have a corresponding elastic stiffness, for example, consists of at least one thermoplastic.
  • The fiber layer pieces 39a . 39b . 39c and 39d on the one hand serve as mechanical protection for the shaft bottom functional layer 37 , with which the shaft bottom 35 is provided. Small particles, such as pebbles, which the breakthroughs 27 the carrier layer 25 penetrate and shank floor functional layer 37 can penetrate and damage them, protecting the shaft bottom functional layer 37 kept away from the fiber layer pieces. In one embodiment of the footwear according to the invention, the fiber layer pieces have 39a . 39b . 39c and 39d additionally a stabilizing function. For this purpose, there are the fiber layer pieces 39a . 39b . 39c and 39d from a mechanically mechanically solidified fiber material of the type already mentioned with at least two fiber components of different melting temperature and correspondingly different softening temperature. By selecting the ratio of the proportions of the two different melting temperature fiber component and by the degree of heating and thus the softening of the second fiber component, on the one hand, the thermal solidification and on the other hand, the water vapor permeability of the fiber layer can be influenced as desired. Due to their thermal solidification, the fiber layer 39 or can the fiber layer pieces 39a . 39b . 39c and 39d as stabilizing elements for the sole unit 15 serve.
  • The fiber layer 39 as such is already known WO 2007/101624 A1 , Further details regarding the fiber layer 39 from which the fiber layer pieces 39a . 39b . 39c and 39d exist, both in terms of choice of material and material composition as well as in terms of production and thermal activation, are therefore not given at this point in more detail but can the WO 2007/101624 A1 be removed. The same applies to details regarding the outsole 29 , the pedal damping position 31 and the carrier layer 25 , for example, in terms of structure, shape and materials used, which is also the WO 2007/101624 A1 can be removed.
  • As has already been mentioned before, this has practical Embodiments used fiber layer material has the disadvantage that for the second fiber component with the lower melting temperature used material does not stain because of The dyeing temperatures are needed above the melting temperature of this fiber component lie. Therefore lets at most the fiber component with this fiber sheet material the higher melting temperature, while the second fiber component with the lower melting temperature remains white. Therefore, as already stated, the optical and aesthetic design possibilities for the fiber layer set very narrow limits.
  • This problem is with a decorative layer according to the invention 45 remedied in the 1 and 2 than in the openings 27 visible grid and explained in the following 4 and 5 each represented by a series of square dots. In the in the 1 and 2 illustrated embodiment of a sole unit 15 are several decorative layer pieces 45 provided, each one of the openings 27 the stabilization situation 25 are assigned and depending on the dimensions of each associated aperture 27 have, according to the in 3 shown fiber layer pieces 39a . 39b . 39c and 39d , In this way, the through the respective of the openings 27 visible underside of each of these fiber ply pieces 39a . 39b . 39c and 39d laminated by an associated decorative layer piece and thus made invisible. As for the decorative layer 45 almost any materials can be used, as long as they are on the one hand colored or dyeable and on the other hand water vapor permeable, is the desired color and patterning of the decorative layer 45 barely set a limit.
