shoes, especially sneakers

technical field

The invention relates to a shoe, especially a sports shoe, comprising an upper and a sole connected to the upper, wherein the upper comprises an outer surface and an inner surface and wherein the inner surface faces the foot of the wearer of the shoe.

Background technique

For common types of shoes, several embodiments are known to design shoe stability with a minimum use of material. The minimal use of materials not only results in lower costs when producing the shoe, but also results in a lightweight shoe where the regular purpose lies.

Especially with football boots, one goal is to design the boot in such a way that the feel to the ball is optimized, ie the ball contact should feel better for the player. Previously known solutions are not always satisfactory in this respect. Furthermore, it is sometimes disadvantageous that the elasticity of the material of the upper is unnecessarily high. In fact, this can be met by a suitably dense and thick design of the material of the upper, respectively. In this case, however, not only the weight of the shoe is adversely affected; but also the water absorption capacity of the shoe is disadvantageously increased in this case.

Contents of the invention

It is therefore an object of the present invention to further develop a shoe of a general type such that - in the case of football boots - it gives a good ball feel. Furthermore, in the design of lightweight shoes, the elasticity of the material of the upper should be low. Finally, it is aimed at a shoe with a low water absorption capacity.

The solution of the invention to this object is characterized in that the inner surface of the upper is at least partially provided with a ridge structure comprising a plurality of closed continuous ridges arranged on the inner surface.

The closed continuous ridge preferably has a polygonal shape; here in particular triangular, quadrilateral, pentagonal or hexagonal shapes come into consideration. But the closed continuous ridge can also be shaped as a circle.

The closed continuous ridge preferably consists of plastic material. In this case it is preferably provided that the closed continuous ridge is injected or applied to the material of the upper by means of an injection molding process or a casting process.

Thus, instead of an injection molding process, a casting process is also conceivable. In this case, plasticized plastic material, such as polyurethane, is poured into the mould. Subsequently, excess material is removed and wiped off, respectively. The material of the upper (e.g. leather or another material like synthetic leather, mesh or textile material) is placed on the mold and then squeezed by pressing the upper plate against the base plate with the still liquid plastic ridges. Thereby, the liquid plastic material penetrates into the surface of the material of the upper; after hardening, the desired composite result is formed between the upper and the ridge structure.

The closed continuous ridge preferably comprises a maximum extension in the inner surface of between 5mm and 20mm (henceforth the diagonals of the polygonal structures and their diameters respectively shall be understood in the following).

The height of the closed continuous ridge perpendicular to the inner surface is preferably between 0.5 mm and 1.5 mm.

According to a further development of the invention, the inner surface inside the region enclosed by the closed continuous ridge can be provided with a coating. Thus, the coating preferably consists of continuous ridges of material. Thereby, the coating can be separated from the continuous ridge by a gap; in this case, the gap is preferably between 0.25 mm and 0.75 mm. The height of the coating perpendicular to the inner surface is preferably less than the height of the closed continuous ridge; it is preferably between 0.2 mm and 0.5 mm. However, the coating can also have the same height as the continuous ridges. The latter is advantageous if the coating can be used as reinforcement material.

The upper may also include a tongue, wherein the inner side of the tongue is also at least partially provided with a ridge structure.

The sole of the shoe may also have a ridge structure on its inner side, wherein a ridge of adjacent consecutive ridges is in this case preferably connected to another ridge. In this case, the ridge structure is preferably free of any other sole elements, in particular without an insole and an inserted sole, respectively.

It has been found in this respect that it is beneficial when using such a sole (that is, such a sole element) in which a ridge structure (which is open to the upper side) is arranged on its inner surface and the ridge structure is formed for the wearer of the shoe. the direct contact area of the sole of the foot. The wearer will usually indeed be wearing a corresponding sock, but will be standing directly on the ridge structure in the sock. This allows for a good feel for the ball. The upper side of the spine structure is ergonomically adapted to the shape of the foot.

The shoes are preferably football boots. Furthermore, in the field of golf, the shoe can be used advantageously.

The ridge structure preferably has walls with a cross-sectional rectangular shape. This also applies to the coatings mentioned.

Thereby, a further development can be provided in which the outsole of the shoe comprises at least one wedge-shaped protrusion on its bottom side.

Preferably, at least the inner side of the upper has the mentioned ridge structure in the front half of the shoe. However, it would be beneficial for the rear half of the upper to not have a fully ridged structure. In particular, the heel area preferably remains free of ridge structures.

To the extent that the terms "upper" and "sole" are used respectively, this relates to the position of the shoe when it is used as intended and stands on the ground.

The proposed solution is therefore characterized in that the upper comprises, on its inner side, a ridge-shaped, preferably polygonal, in particular hexagonal, structure. Such a structure may also be provided for the inner side of the tongue of the shoe. Furthermore, the sole may also comprise such ridges on the inside, wherein preferably no inner sole rests on the ridges. Instead, the user of the shoe, especially a football player, should only touch the ridge with his sock.

In such a design, advantageously, an improved ball feel and ground feel can be obtained, ie a better ball contact can be felt. Thus, it is selectively also free of foam structures and linings in the upper, and preferably in the tongue, respectively.

The continuous (especially polygonal) ridge structure advantageously eliminates the (respectively) elasticity (and elongation) of the upper; however, in the case of previously known solutions with linings, the material is disadvantageously relatively high elongation.

Furthermore, with the proposed design, the ability to absorb water is advantageously lower than conventional shoes.

detailed description

In FIG. 1 , a shoe 1 can be seen comprising an upper 2 and a sole 3 . Thereby, the upper 2 and the sole 3 are firmly connected to each other. The upper has an outer surface 4 and an inner surface 5, the latter thus facing the foot of the wearer of the shoe.

It can be seen in the overview of the figures that on the inner surface 5 of the upper 2 a ridge structure 6 is arranged. The same ridge structure has a plurality of closed continuous ridges 7 arranged on the inner surface 5 .

As can be seen in FIG. 2 , the ridge structure 6 has a hexagonal shape in the illustrated embodiment, ie the ridge 7 has a hexagonal design that appears perpendicular to the inner surface 5 . However, it should be mentioned that this is not mandatory and this can also only be provided for a part of the inner surface 5 .

Depending on the space available on the inner surface 5, other shapes, in particular triangular, quadrilateral and pentagonal ridges may also be provided.

Preferably, as a possibility, the differently shaped ridge structures are arranged in such a way that the inner side of the upper is completely bordered by the ridges.

It is also possible that parts of the inner surface 5 are not provided with ridge structures 6 .

Likewise, the tongue 10 of the shoe 1 is provided on the inside with the mentioned ridge structure 6 .

A preferred embodiment is shown in FIGS. 2 and 3 . A coating 8 of the base material of the upper 2 is thus provided inside the closed continuous ridge 7 . As shown in section A-B according to FIG. 3 , the coating 8 maintains a gap 9 with the ridge 7 . However, it is also possible to do without this gap, which can be provided in particular with respect to the tongue 10 .

It is also possible to use the coating 8 only in selected areas and to use hollow ridge structures in other areas of the inner surface.

In Figures 2 and 3 further specifications are made in relation to the size of the ridge structure 6 and the ridge 7, respectively.

This thus provides a maximum extension E of the closed continuous ridge 7 comprised in the inner surface 5 of between 5 mm and 20 mm, see FIG. 2 .

As can be seen from Figure 3, the closed continuous ridge 7 has a height H perpendicular to the inner surface 5 of between 0.5 mm and 1.5 mm. The gap 9 has a dimension t (width of the gap) typically between 0.25 mm and 0.75 mm.

The height h of the coating 8 is smaller than the height H of the closed continuous ridge 7; it is preferably between 0.2 mm and 0.5 mm.

In Fig. 3, the width b of the ridge is also indicated, which is preferably between 0.5 mm and 1.5 mm.

Furthermore, the thickness d of the shoe upper 2 is indicated, which can also be in the region between 0.5 mm and 1.5 mm. Here, a single-layer material is preferred, such as leather, on which the ridge structure is applied directly by injection moulding.
