Description

[0001] Shoe with interchangeable parts

[0002] The present invention relates to a shoe comprising a shoe frame, wherein the shoe (1) comprises at least one replaceable part, a shoe set comprising the shoe, a method for producing the shoe with at least one replaceable part, the shoe frame, and the use of the shoe and the shoe frame.

[0003] Every shoe gets worn out with wear. Restoring worn areas is often time-consuming and expensive, resulting in shoes being thrown away even if they are otherwise in good condition. Also, some shoes are rarely worn because, for example, their color only matches a specific dress. Therefore, people often buy the same shoes in different colors to optimally match the dress color.

[0004] In addition, foot size can change, for example in children's feet or when warm socks are put on.

[0005] The reasons mentioned above result in shoes being thrown away even though they are still completely, or at least mostly, perfect. This wastes both the raw materials used to make shoes and the energy required for their production. However, in our time, it is more important than ever to use our resources sparingly.

[0006] In addition, after wear and tear, or when the child's foot becomes larger than the shoe, the shoe is usually disposed of and thus usually incinerated or disassembled into its individual parts and recycled.

[0007] It is therefore the object of the present invention to provide a shoe with replaceable parts in which worn areas can be easily replaced and / or which can be easily adapted to different foot sizes. Furthermore, it should also be possible to easily change the external appearance to match the color of the shoe to the color of the clothing, thus reducing the number of shoes in the shoe cupboard at home and making better use of existing shoes.

[0008] This challenging problem was solved with a shoe (1) according to claim 1.

[0009] The invention also relates to a shoe set (8) according to claim 10.

[0010] In addition, a method for producing the shoe (1) according to claim 11 is also claimed.

[0011] The shoe frame (2) according to claim 12 is also claimed.

[0012] The use of the shoe (1) according to the invention according to claim 14 and of the shoe frame according to claim 15 is also claimed.

[0013] It is therefore also claimed that the shoe (1) and the shoe frame (2) can be taken apart and an intermediate element can be inserted, whereby the shoe (1) can be adapted to changed shoe sizes.

[0014] The shoe (1) according to the invention comprises a sole (3) and at least one replaceable part, wherein the at least one replaceable part is in the form of a reversibly attachable coating element (5), a side element (10), and / or a front (1b) and / or rear part (1c) of the shoe (1) with optionally an intermediate element (9) which can be inserted and attached between the front (1b) and rear part (1c) of the shoe (1), wherein, if the shoe (1) has at least one coating element (5), the shoe (1) comprises a shoe frame (2) on which the at least one coating element (5) is arranged, and the shoe frame (2) and / or the sole (3) have at least one means (4) and the at least one replaceable part have at least one means (4a) for reversibly attaching the shoe frame (2) and / or the sole (3) to the at least one replaceable part, wherein the means (4) cooperate with the means (4a).

[0015] If the at least one replaceable part is in the form of reversibly attachable coating elements (5), the shoe (1) comprises the shoe frame (2), on the outside of which means (4) for attaching reversibly attachable coating elements (5), i.e. with replaceable and thus removable parts. The coating elements (5) can be used for the outside and / or the inside of the shoe (1). The coating elements (5) used for the outside preferably have a decorative coating. Thus, coating elements with different decorative coatings can be individually combined. Furthermore, it is possible to convert a shoe, for example a light summer shoe, into a completely different type of shoe, for example a sturdier shoe with a water-protective surface, by changing the coating elements (5).Alternatively, the appearance of the shoe (1) can also be changed, for example by replacing the coating elements (5) having a first color and / or feel with ones having a different, second color and / or feel. Furthermore, it is also possible in a simple manner to replace damaged or worn areas of a shoe by exchanging the respective coating element(s) (5) by replacing the damaged or worn coating element (5) with a new one of the same type. If the at least one coating element (5) is suitable for the inside of the shoe (1), it is preferably in the form of a reversibly attachable inner layer.

[0016] If the at least one, preferably two or more, replaceable part is in the form of at least one side element (10), the shoe (1) comprises at least two, preferably at least three, parts that can be reversibly joined together in a simple manner, for example using click and / or snap-in elements. The means (4a) of the at least one side element (10) interact with the means (4) of the sole (3), for example using click and / or snap-in elements. The shoe frame (2)—optional in this embodiment—can be connected to the outer part of the side element (10), which together are reversibly connected to the sole (3). The shoe (1) can also have an insole that is attached directly to the sole (3) or that is arranged on the at least one side element (10).

[0017] If the shoe (1) comprises at least one side element (10), this can be quickly and easily adapted to the worn garment - be it in terms of color, feel, or specific design, while the sole (3) remains the same. And when the tip of the shoe (1) is worn out, only the front side element (10) needs to be replaced, and not the entire shoe. If the side element (10) comprises at least two parts, a front part (1b) and a back part (1c) are obtained, which, together with the sole (3), form the shoe (1). A non-limiting embodiment with two side elements (10) is shown in Fig. 9.

[0018] If the at least one replaceable part is in the form of a front part (1b) and / or a back part (1c) of the shoe (1), the shoe (1) can be easily adapted to the foot size of children with growing feet, since the shoe (1) is made up of at least two parts. If, for example, the back part (1c) of the shoe (1) is available in two different sizes, the shoe (1) can first be assembled from the smaller back part (1c) and the front part (1b) of the shoe (1). As the child's foot grows, the smaller back part (1c) can be removed and replaced by the larger back part (1c). In this way, the same shoe (1) can be used for feet of different sizes, which differ by 2-3 sizes, for example.

[0019] Alternatively, the shoe (1) with a front (1b) and rear (1c) part can be supplemented by an intermediate element (9). The front (1b) is separated from the rear (1c), the intermediate element (9) is inserted between them, and then reconnected.

[0020] The intermediate element (9) comprises two lateral strips which extend the sides of the shoe accordingly, wherein the two strips are connected to one another in the base / sole region. The base / sole region can be designed in the form of a sole element, i.e. this part also extends the shoe sole (3) by inserting the intermediate element (9). Alternatively, the region is designed in the form of an insole. This embodiment is suitable if a separate shoe sole (3) with matching dimensions is reversibly attached to the assembled shoe. In addition, the intermediate element (9) also comprises means (4, 4a) with which the intermediate element (9) is reversibly connected to the front (1b) and rear part (1c).

[0021] If the shoe (1) comprises front (1b) and rear parts (1c) and optionally an intermediate element (9), these can comprise a shoe frame (2) on which at least one coating element (5) can be reversibly arranged (Fig. 11a, 11b, 12). Alternatively, the shoe (1) does not comprise a shoe frame (2) or any means (4), but directly forms the shoe surface, for example in the form of a side element (10).

[0022] The soles (3) as well as the side edges of the front (1b) and rear parts (1c) and optionally of the intermediate element (9) comprise means (4, 4a) which interact with one another so that the assembled shoe (1) forms a unit until the at least one replaceable part is deliberately removed. Alternatively, the soles (3) are one-piece and can be reversibly attached to the assembled shoe consisting of the front (1b) and rear parts (1c) and optionally the intermediate element (9). In this embodiment, a smaller or larger sole (3) is attached to the assembled shoe, depending on whether a smaller or larger front (1b) or rear part (1c) is used, or with or without the intermediate element (9). In this embodiment, the front (1b) and rear parts (1c) and optionally the intermediate element (9) can also be regarded as side elements (10) which can be reversibly combined with a sole (3).

[0023] In this case, a shoe (1) is understood to be a shoe that can be put on a foot of the appropriate size. The shoe (1) thus at least partially surrounds the foot, with the sole of the foot lying on the upper side of the insole, and the shoe structure (2) - if present - usually surrounds the sole (3) and / or at least partially over the instep, optionally the ankle and the lower leg, or part thereof. The means (4) with which the coating elements (5) and optionally the other replaceable parts can be reversibly fastened and - in the case of different types of coating elements - individually combined are arranged on the shoe structure (2) and / or the sole (3).

[0024] The shoe (1) is designed as a right or left shoe (1), whereby generally a pair of shoes is offered and purchased, comprising a right shoe and a symmetrical left shoe (1). If the shoe (1) is equipped with reversibly attachable coating elements (5), it forms the shoe (1) that is worn. Instead of a shoe (1), a shoe set (8) can also be offered or purchased, and instead of a pair of shoes, a pair of shoe sets can also be offered or purchased.

[0025] The shoe (1) can be a women's, men's, or children's shoe. The shape of the shoe is typically defined by the shoe frame (2), ie, the movable intermediate support, the at least one side element (10), and / or the front (1b) and / or rear part (1c) of the shoe (1).

[0026] Suitable, non-limiting shoes (1 ) include ballerinas; boots such as ankle boots, biker boots, Chelsea boots, cowboy boots and over-the-knee boots; brogues; Budapesters; car shoes; Chucks; clogs; college shoes; creepers; Crocs; penny loafers; Derbys; desert boots; espadrilles; Fiats; Fivefingers; galoshes; Haferl shoes; high heels; loafers; Mary Janes; moccasins; moon boots; Mukluks; mules; over-the-knee boots; Oxfords; peel-toes; slippers; sabots; sailing shoes; skyscrapers; slingbacks; slippers; sneakers; ankle boots; T-strap pumps; wedges; flip-flops; trainers; hiking boots; slippers; and boots. Trainers and hiking boots are generally also suitable for walking, even over longer distances.

[0027] The shoe frame (2) of the shoe (1) is preferably

[0028] - firmly connected to the sole (3), in particular firmly glued to the sole (3), or - reversibly connected to the sole (3), wherein the shoe frame (2) is made of one or more pieces, wherein, if the sole (3) is made of one piece, the shoe frame (2) is preferably also made of one piece. The shoe frame (2) is preferably flat or net-like.

[0029] If the shoe (1) comprises at least one side element (10) or a front part (1b) and rear part (1c) and optionally an intermediate element (9), the shoe frame (2) is optional and - if present - preferably multi-part and part of the side element (10) or the front part (1b) and rear part (1c) and - if present - of the intermediate element (9).

[0030] It is also possible for the sole (3) to be reversibly removed from the shoe structure (2). Furthermore, it is possible for the shoe structure (2) to be in the form of a shoe insole only, and for the reversibly attachable coating elements (5), for example in the form of softer shell elements, and thus as side elements (10), to be attached to the insole or between the insole and the shoe sole (3), for example by means of click or snap-in elements. The shoe sole (3) is understood to be the part of the shoe (1) which forms the lower side of the shoe (1) and at least partially touches the ground when walking. In contrast to the shoe sole (3), the insole of the shoe (1) is arranged on the inside of the shoe (1), with the foot touching the inside when wearing the shoe (1).

[0031] The term «shoe frame firmly connected to the sole (3)» means that the shoe frame (2) and the sole (3) cannot be separated from one another, i.e. irreversibly and thus not without destruction. This allows a permanent connection of the sole (3) to the shoe frame (2) without the sole becoming detached from the rest of the shoe (1). The sole is typically based on rubber, natural rubber, leather, artificial leather, wood, recycled material, in particular recycled plastic, cast material, in particular cast plastic, printed material, for example by means of a 3D printer, and / or suitable plastics, which may also be in the form of composites. In addition, the shoe frame (2) is preferably movable, i.e. easily deformable by hand.The shoe frame (2) preferably has a flexural modulus Ef according to DIN EN ISO 178 of 50 to 5,000 MPa, in particular of 100 to 3,000 MPa, and a wall thickness of 1 to 8 mm, in particular of 1 to 5 mm, measured according to DIN 862 / Form A1 with a micrometer. The means (4) are not taken into account when determining the wall thickness.

[0032] The shoe frame (2) is preferably based on natural rubber, latex, textile, leather, plastic, recycled material, for example plastic-based, or printed material, for example using a 3D printer. It is therefore movable, i.e. not rigid, and deforms or generally moves when the shoe (1) is used, i.e. typically when walking. The shoe frame (2) can be fully formed, wherein the shoe frame (2) can optionally contain openings to facilitate air permeability and thus breathability. Alternatively, the shoe frame (2) can also be in the form of a frame, net, mesh, skeleton, honeycomb, or partial skeleton, which makes it more flexible due to its structure and can be easily stretched. The shoe frame (2), i.e. the holder (2), typically provides stability to the shoe (1) with coating elements (5).For example, the shoe frame (2) can be in the form of a spider-like structure, to which the at least one fastening element (5), for example a click-tight and moldable fastening element, can be reversibly inserted. Alternatively, the shoe frame (2), i.e., the shoe skeleton, can have a honeycomb structure. This shoe skeleton can consist of a single piece with a predefined shape, or it can be made up of multiple pieces, for example, in the form of a front (1b) and / or rear part (1c), optionally with an intermediate element (9).

[0033] Suitable means (4, 4a) for reversible fastening, i.e., connecting the shoe frame (2) and / or the sole (3) to the at least one replaceable part (5, 1b, 1c, 9), include eyelets or eyelets, hook-and-loop fasteners with barbs or loops, click and / or snap-in elements, and / or a zipper. The latter is particularly preferred if the shoe (1) comprises a front (1b) and rear part (1c), optionally with an intermediate element (9), wherein the sides of the front (1b) and rear parts (1c) can be closed by means of a zipper (see Fig. 12). Alternatively, the sides can have an extended inner side, for example with a hook-and-loop fastener as means (4a), which can interact with the means (4) on the inner side of the front part (1b) of the shoe (1). Such an embodiment is shown, for example, in Fig. 11b).In both cases, the sole parts comprise cooperating means (4, 4a), for example in the form of a click and / or snap-in element.

[0034] The shoe frame (2) can also contain means (4) on the inside, ie on the side of the shoe frame (2) facing the foot to be accommodated, for attaching a reversibly attachable inner layer, for example, padding. This inner layer comprises means (4a) which cooperate with the means (4) of the shoe frame (2) to reversibly connect the inner layer to the shoe frame (2).

[0035] In a preferred embodiment, the shoe frame (2) and / or at least one replaceable part, and thus the shoe (1), comprises at least one movable region (6) which can be reversibly deformed when walking. The movable region (6) allows the foot to roll easily when walking, whereby the sole (3) - and thus also the shoe frame - can be deformed or moved. While this is the case with almost all conventional shoes, it is generally extremely helpful in particular with the shoe (1) according to the invention with arranged coating elements (5). While the movable region (6) of the shoe frame (2) is folded or contracted when walking in order to enable the sole (3) to bend, this is not the case for the coating elements (5) arranged on the shoe (1).Therefore, it is typically helpful not to arrange any means (4) in the movable area (6) that would lead to unnecessary fixation of the coating elements (5). The shoe frame (2) is advantageously flexible, i.e., stretchable, in the area of ​​the movable area (6), for example due to its structure and / or the material used.

[0036] The coating elements (5), which can be reversibly attached to the shoe (1), have an outer side and an inner side, i.e. the side facing the shoe frame (2), the inner side interacting with the means (4) on the shoe frame (2). The reversibly attachable coating elements (5), which can be arranged on the shoe frame (2) of the shoe (1), allow the coating elements (5) to be easily replaced. This is particularly useful when a coating element (5) is worn or destroyed, or when the shoe is to be given a different appearance, for example a different color.

[0037] If the at least one replaceable part is in the form of reversibly attachable coating elements (5), the shoe (1) typically comprises at least two coating elements (5). It can also be advantageous - particularly in the case of lightweight and flexible shoes - for the shoe (1) to comprise a plurality of, for example, at least three, and often four or more, different coating elements (5), which are arranged side by side on the shoe such that they cover the entire shoe structure (2). The manufacturer of the shoe (1) typically selects how the individual coating elements (5) are arranged on the shoe structure (2).

[0038] The various coating elements (5) of a shoe (1) generally have different shapes, such as dimensions and / or curvature. The respective shape typically depends on the type of shoe (1) and the location of the coating element (5) on the shoe (1).

[0039] In a preferred embodiment, the shoe frame (2), and thus the shoe (1), can be adjusted in size, particularly in length. This means that the shoe skeleton (2), to which the coating elements (5) can be attached on the outside and which can optionally have different coatings on the inside, can be adapted to different shoe sizes. The shoe skeleton (2) is, for example, made up of two or more parts, whereby an additional extension element, i.e., an intermediate element (9), can be inserted between these parts. The sole (3) can also be made up of several parts, with each part being connected to the corresponding part of the shoe skeleton (2). Alternatively, soles (3) of different sizes can be connected to the joined front (1b) and rear parts (1c) - with or without an intermediate element (9). This allows the shoe (1) to be adapted to the desired size of the foot.The various parts of the shoe skeleton, as well as the intermediate element, can be reversibly fastened to one another, for example, using click or snap-in elements. These are typically attached in the area of ​​the insole and / or sole (3), and advantageously also above the insole, for example, at the instep.

[0040] The coating elements (5), side elements (10), and / or the front (1b) and / or rear part (1c) can be made of a soft and flexible material, such as a textile, or of a hard, immobile material, such as plastic, depending on the shoe type. The coating elements (5) preferably have a flexural modulus Ef according to DIN EN ISO 178 of 10 to 20,000 MPa, in particular of 50 to 15,000 MPa, and a wall thickness of, for example, 1 mm to 1 cm, in particular of 1 to 5 mm, measured according to DIN 862 / Form A1 using a micrometer.

[0041] The edge regions of the coating elements (5) can be shaped in the form of a straight surface which touches one another, for example over their entire surface. If the shoe frame (2) is to have a certain degree of mobility, for example in the region of the movable area (6), it is advantageous if the movement elements (5) do not lie tightly against one another. In particular, if the layer of the movement elements (5) has a different lateral extension, i.e. in the direction of the movement element (5), in relation to the surface of the shoe frame (2) due to the bending of the layers - for example when the shoe frame (2) bends while walking - it is very advantageous if the sides of the movement elements (5) are shaped in such a way that they can accommodate the different longitudinal extensions.

[0042] Non-imitative embodiments of edge regions of coating elements (5) suitable for accommodating different lateral dimensions include L-shaped edge regions and tongue-and-groove joints. It is also possible to provide a receptacle using a T-shaped spacer (7), into which, for example, rectangular edge regions engage. Alternatively, thin, movable and / or tensionable coating elements (5) can be arranged over the entire surface of movable regions (6).

[0043] The coating elements (5), side elements (10), and / or the front (1b) and / or rear part (1c) preferably comprise, on their inner side, at least one means (4a) for fastening to the shoe frame (2) and / or the sole (3), wherein the means (4a) interact with the means (4) attached to the shoe frame (2) or the sole (3). Preferred means (4a) for the coating elements (5) and the front (1b) and / or rear part (1c), as well as optionally the intermediate element (9), comprise eyelet buttons or eyelet holes, hook-and-loop fasteners with loops or barbs, click and / or snap-in elements. Preferred means (4a) for the side elements (10) comprise click and / or snap-in elements.

[0044] The coating elements (5) have an outer and an inner side, wherein

[0045] - the inner side comprises at least one means (4a), and / or

[0046] - the outer and / or inner side comprises a lignin, leather, textile, plastic, recycled material such as recycled plastic, printed material, for example by 3D printing, woven material, rubber, wood, braided natural fibers, polylactide (PLA) and its derivatives such as Polylactide Light Weight (PLA LW) or PLA Purifier, nylon, filament textile fiber such as Recreus filaments, Filaflex or Reciflex, polyethylene terephthalate (PET) and its derivatives such as polyethylene terephthalate glycol (PETG) or PET-G CF filament, polypropylene (PP), polypropylene glass fiber (PP GF), and / or flexible wood, wood or lacquer layer, wherein the outer side is preferably designed as a decorative layer. These materials allow the attachment of the means (4a) to the coating elements (5). A decorative layer is understood to be a visually attractive layer which is characterized by a suitable color, varnish, surface structure, pattern and / or feel.

[0047] In another preferred embodiment, if the shoe (1) has at least two coating elements (5), it comprises at least one spacer (7), wherein the spacer (7) delimits the coating elements (5) and optionally encloses their edges. The at least one spacer (7), also called a spacer or intermediate piece, is preferably, and optionally reversibly, connected to the shoe frame (2) or the coating elements (5). The at least one spacer (7) forms the regions into which the coating elements (5) are fitted, wherein the at least one spacer (7) can overlap the edge regions of the coating elements (5). The at least one spacer (7) can be arranged along the edges and / or at the respective corner regions of the coating elements (5).It can also be made of rubber or rubber-like material, for example, which makes the spacer (7) bendable and flexible, but can also serve as a waterproof element between two coating elements (5).

[0048] The at least one spacer (7) of the shoe (1) is preferably

[0049] - one-piece and has a net shape, for example with a click and / or snap-in device for receiving the coating elements (5), wherein the one-piece spacer (7) is preferably reversibly attachable to the shoe frame (2) or is part of the shoe frame (2),

[0050] - multi-part, wherein the spacers (7) o at least partially delimit the edge regions of the coating elements (5), and / or o surround the corner regions of the coating elements (5), wherein the at least one spacer (7) is fastened to the shoe frame (2), optionally reversibly, held by the coating elements (5), and / or is part of a coating element (5). If the spacer (7) is part of a coating element (5), the spacer (7), typically in the form of another, soft material such as rubber or rubber-like material, is subsequently fastened to the spacer (7).

[0051] In another preferred embodiment of the shoe (1), the edge regions of the coating elements (5), side elements (10) and / or front (1b) and / or rear part (1c), and optionally the at least one spacer (7) and / or intermediate element (10), at least in the region of the movable region (6) of the shoe frame (2), are designed such that the coating elements (5) can reversibly absorb changes in the distance of the shoe frame (2) due to deformations when walking.

[0052] The shoe set (8) according to the invention comprises

[0053] - the shoe according to the invention (1 ),

[0054] - at least two different sets of coating elements (5) with which the shoe frame (2) of the shoe (1) can be individually and reversibly coated, and optionally at least one spacer (7),

[0055] - at least two interchangeable side elements (10),

[0056] - comprises at least two front (1b) or rear parts (1c) of different sizes, which, when assembled to form the shoe (1), form a shoe with a different shoe size, and / or

[0057] - at least one front part (1 b), one rear part (1 c), and one intermediate element (9), or optionally two or more intermediate elements (9) with different dimensions.

[0058] In addition, the shoe set (8) can also comprise at least two soles of different sizes if the shoe set (8) comprises at least a front part (1 b), a rear part (1 c) and optionally an intermediate element (9).

[0059] A set of coating elements (5) is understood to mean all coating elements (5) that are required to completely cover the shoe (1) with coating elements (5). In the case of two (2) sets of coating elements (5), the two sets can be identical or different, whereby, however, the number, dimensions and, if applicable, curvature of the coating elements (5) remain the same for each set. If they are identical, the individual coating elements (5) are used in particular to replace worn or destroyed coating elements (5). If they are different, they serve in particular to give the shoe a different appearance, for example in the form of a different color, and / or a different feel, for example, instead of a smooth surface, one with a pronounced 3D profile, for example with imitation crocodile leather.This makes it possible to convert a shoe, for example a lightweight summer shoe, into a completely different shoe type, such as a sturdier shoe with a water-resistant surface, by changing the coating elements (5). This makes it possible to only require a few different shoes (1) with a shoe frame (2) and sole (3), which can be transformed into a multitude of different shoes (1) using appropriate coating elements (5).

[0060] In the method according to the invention for producing the shoe (1) with at least one replaceable part,

[0061] - the coating elements (5) are fastened to the shoe frame (2), wherein the means (4a) of the coating elements (5), in particular the means (4a) arranged on the inside, are connected to the means (4) on the shoe frame (2) and / or on the sole (3), whereby the shoe (1) according to the invention is obtained

[0062] - the front part (1 b) is joined to the rear part (1 c), whereby the means (4, 4a) of the front (1 b) and rear parts (1 c) are brought into connection with each other, and / or

[0063] - an intermediate element (9) is reversibly inserted between the front part (1b) and the rear part (1c), the means (4, 4a) of the front (1b) and rear parts (1c) and of the intermediate element (9) being connected to one another.

[0064] If the shoe (1) has at least two replaceable parts in the form of coating elements (5), in a preferred embodiment, at least one spacer (7) is arranged between the coating elements (5) in the method for producing the shoe (1).

[0065] The shoe frame (2) according to the invention for producing the shoe (1) comprises at least one means (4) for the reversible fastening of at least one coating element (5).

[0066] The shoe frame is preferably one-part or multi-part, wherein the shoe frame (2) is firmly or reversibly connected to the sole (3) and / or is flat and optionally has small openings which preferably amount to 20% or less, in particular at most 10% or less, of the total surface area of ​​the shoe frame (2), or that the shoe frame is in the form of a frame, net, mesh, skeleton or honeycomb, wherein the total surface area of ​​the openings is preferably more than 20%, in particular more than 30%, of the shoe frame (2).

[0067] The use of the shoe (1) according to the invention comprises the

[0068] - individual replacement and / or combination of different coating elements (5), whereby the shoe (1) can be provided with different decorative coatings and / or damaged or worn coating elements (5) can be replaced, and / or

[0069] - individual adjustment of the shoe size.

[0085] In the following, non-limiting, preferred embodiments of the shoes (1) according to the invention and of the shoe set (8) according to the invention are described with reference to the following drawings, which are not to be interpreted in a restrictive manner and are understood as part of the description:

[0086] Fig. 1 shows an example of a section of the shoe frame (2), i.e., the shoe skeleton. This serves as a holder for the coating elements (5), provides stability to the shoe (1), and typically defines the shape of the shoe (1). Means (4) are attached to the outside of the shoe frame (2), for example in the form of eyelet heads, which interact with the means (4a), for example in the form of eyelet holes, which are attached to the coating elements (5).

[0087] Fig. 2 shows the inside of a coating element (5) with means (4a), for example in the form of eyelet holes, which are attached to the inside of the coating element (5).

[0088] Fig. 3a shows a patterned outer side of the coating element (5).

[0089] Fig. 3b shows a single-color outer surface of the coating element (5). Fig. 4 shows the inner surface of an exemplary removable shoe sole (3) coated with an adhesive. This inner surface can be attached to the underside of the shoe frame (2), for example, to the underside of the insole of the shoe (1).

[0090] Fig. 5 shows the outside of the removable shoe sole (3), which can be equipped with or without a profile sole.

[0091] Fig. 6 shows, by way of example, two coating elements (5) arranged side by side, with a spacer (7) arranged between them, for example in the form of a plastic-to-fabric stability spacer, a rubber holder, or a rubber-like material, i.e., a closing part between two coating elements (5). The spacer (7) is shown separately, with the arrow indicating the correct position.

[0092] Fig. 7 shows, by way of example, a non-limiting embodiment of the edge region of coating elements (5) in the form of a T-shaped spacer (7), wherein the lateral coating elements (5) engage between the shoe frame (2) and the upper part of the spacer (7). As a result, the coating elements (5), which are connected to the shoe frame (2) by means (4, 4a), can move laterally without any problems, and thus parallel to the surface of the shoe frame (2), without the latter being partially unprotected by the movement. The T-shaped spacer (7) is connected to the movable region (6) of the shoe (1) by means (4, 4a).

[0093] Fig. 8a-d show further non-limiting embodiments of edge regions of two coating elements (5; A and B), which are suitable for accommodating different lateral extensions, such as L-shaped edge regions (Fig. 8a) and tongue and groove connection (Fig. 8b).

[0094] Alternatively, the edge areas of the coating elements (5) can be rectangular or slightly sloped, for example. This design is particularly suitable for areas of the shoe frame (2) that require less mobility.

[0095] Fig. 9 shows, by way of example, a shoe (1) in the form of a high heel. The replaceable parts are in the form of, for example, two side elements, i.e., a front and a rear side element (10). These can be reversibly connected to the sole (3) of the shoe (1). Alternatively, the side element can also be a single piece.

[0096] Optionally, the side elements (10) can have an insole, which can be attached to the sole (3) together with the side elements (10) and on which the foot rests during wear. Alternatively—and optionally—the insole can be connected directly to the sole (3).

[0097] The sole (3) has means (4, not shown) with which the means (4a) of the side elements (10) interact. Suitable means (4, 4a) in this embodiment are click and / or snap-in elements.

[0098] The rear shell element of the side elements (10) has a movable region (6) in the front part, which can, for example, have an L-shaped (see Fig. 8a) or a groove- or tongue-shaped (see Fig. 8b) edge region. The corresponding, possibly cooperating, edge region of the front side element (10) is not shown.

[0099] Fig. 10 shows an example of a bootie shoe (1) with a sole (3) with, for example, three different coating elements (5) as replaceable parts. The underlying shoe frame (2) is not shown.

[0100] The front and rear coating element (5) can be made of harder material, while the larger part covering the instep and ankle can be made of more flexible material.

[0101] Fig. 11 ab shows a sneaker (1) with a sole (3) which is suitable for growing children’s feet, for example.

[0102] The trainer (1) is two-part and comprises a front (1b) and a rear (1c) shoe part. The rear shoe part (1c) is available in two different shoe sizes, ie, the assembled trainer (1) with the front (1b) and rear (1c) shoe parts can be easily lengthened or shortened by exchanging the rear shoe part (1c).

[0103] The front shoe part (1b) is identical in Fig. 11a and Fig. 11b and comprises, for example, coating elements (5) on both sides of the shoe, as well as in the front area of ​​the shoe (1). The shoe frame (2, not shown) is located behind the coating elements (5).

[0104] Fig. 11 a shows a slightly shorter rear shoe part (1c), whereby the means (4, 4a) are not shown.

[0105] Fig. 11 b shows the somewhat longer rear shoe part (1c) with an exemplary extended inner side comprising at least one means (4a), for example in the form of a hook-and-loop fastener, which can interact with the inner side of the front shoe part (1b). In addition, the shoe sole (3) preferably also has means (4, 4a, not shown), for example in the form of click and / or snap-in elements, with which the two sole parts can be reversibly joined together. Alternatively, a sole (3) of different sizes can be subsequently attached to the joined front (1b) and rear parts (1c) of the shoe (1).

[0106] Fig. 12 shows an example of a sneaker (1) with a front (1b) and rear part (1c) as well as an intermediate element (9) which can be inserted or removed between the front (1b) and rear (1c) shoe part depending on the desired shoe size.

[0107] The three shoe parts (1 b, 1 c, 9) comprise, for example, coating elements (5) which are attached to the shoe frame (2, not shown).

[0108] The intermediate element (9) and the shoe parts (1b, 1c) also have means (4, 4a, not shown) for connecting the shoe parts (1b, 1c) to each other or to the intermediate element (9). A suitable means (4, 4a) can be, for example, a zipper, which can close the lateral parts together.

[0109] The areas of the sole (3) to be joined together can comprise, for example, click and / or snap-in elements as means (4, 4a). Alternatively, the shoe set (8) can comprise soles (3) of different sizes. In this embodiment, the front (1b) and rear (1c) parts, as well as the intermediate element (9) of the shoe, are designed without soles (3). However, when assembled as a shoe (1), a sole (3) of the corresponding size can be attached thereto.
