Description

The invention relates to a shoe, in particular running shoe, according to the preamble of claim 1.

Running shoes, which are adapted to the particular needs of a runner, are known in the art, with the example of the DE 20 2005 013 798 U1 is referenced. In such running shoes, the ball of the foot is arranged centrally above a rolling or tipping line of an underside of the sole (ball roller). The rolling or tilting line determines at which time the heel of the current person lifts. Overall, the running shoes mentioned in the prior art are perceived as unsatisfactory, especially in ergonomic terms, such shoes are disadvantageous in the prior art, especially due to the occurrence of high pressure loads during running and especially when unwinding, for diabetics.

It is therefore an object of the present invention to provide a shoe, in particular running shoe, which solves the aforementioned problems and leads to improved ergonomics and at the same time improved distribution of forces while running.

This object is achieved by a shoe, in particular running shoe according to claim 1.

In particular, the object is achieved by a shoe, preferably a running shoe, having a predetermined bale line extending from an inner ball point to an outer ball point and having a bale roller which is offset rearwardly toward a heel end by a mean bale roll distance from the ball line. the shoe further comprising a shaft and an insole disposed over the outsole bonded to a shaft edge at an upper surface of the outsole.

An important idea of the invention is that a rolling or tilting line is offset in a shoe according to the invention relative to the ball of the foot to the rear. This has the consequence that the shoe rolls off the bale while running. This in turn reduces a rolling resistance and thereby improves the ergonomics and concomitantly occurring during running pressure loads, which is particularly for people with skin and / or circulation problems, especially in the legs and / or feet, a great advantage.

The bale line determines the bale position and is an imaginary line between the bale of the big and small toe (or between an inner and an outer bale). The ball line is thus determined on the basis of predetermined proportions of an individual foot or of an average foot that forms the basis of the shoe. Each shoe thus has a clearly defined bale line, which can be determined with customary measurements. For example, the bale line may divide a sole length into 37% forefoot length and 63% hind foot length.

At the same time, the shoe according to the invention has a shaft and an insole glued to the upper side of the outsole. This measure according to the invention increases the stability of the shoe, in particular the running shoe, and thus improves the grip of a foot in the shoe, whereby the stiffness, in particular torsional rigidity, of the shoe is optimized by the insole glued to the upper side of the outsole.

According to one embodiment of the invention, the insole is rigid, d. H. in normal use stiff, namely torsion and bending resistant trained. Advantageously, the torsional rigidity or torsional stability of the shoe according to the invention and in particular the torsional rigidity or torsional stability of the outsole thereof can be further improved, so that in use of the shoe according to the invention, a pressure load acting on a sole of the foot is distributed substantially evenly over the substantially entire sole of the foot is, and in particular during running, no pressure peaks occur, as is the case with conventional shoes known from the prior art, which is especially for people with skin and / or circulation problems, especially in the legs and / or feet, painful and is therefore disadvantageous. An inventive shoe is thus particularly well suited for such a group of people, the shoe according to the invention is due to its optimized properties for all other people particularly comfortable and comfortable to wear and is particularly well suited for walking, walking, walking and running.

According to one embodiment of the invention, the shoe according to the invention, in particular running shoe, has a tarsal area and a metatarsal zone, wherein the tarsal area at an inner tarsal area edge portion is on average softer than at an outer tarsal area edge portion and / or Metatarsal area at an inner Midfoot edge portion is formed on average harder than at an outer midfoot portion edge portion. Here and below, the terms "inside" and "inner" mean that the referenced element in use of a pair of shoes facing the other shoe. Accordingly, "outside" or "outside" is intended to mean that the referenced element in the use of the shoe pair is the other shoe further. By "hardness", the mechanical resistance can be understood that opposes the material of one edge portion of a test specimen of the material of the other edge portion. The hardness can be measured, for example, according to Mohs, Martens or Brinell.

According to a still more general idea, the inner tarsal region edge portion may be configured to averagely resist this lower than the outer tarsal region edge portion when placing the foot on average. Likewise, the inner midfoot portion edge portion may be configured to provide greater resistance than the outer midfoot portion edge portion when placed on average. This can be achieved for example by a different bulge or profiling, in particular tread depth. In this way, the shoe according to the invention can be optimally adapted to the needs of a consumer or user.

In any case, such an adjustment of the mechanical resistance of the outsole allows a particularly ergonomic running. In particular, the course of resistance of the sole of the natural S-shaped rolling line of the human so follows that on a foot located in the shoe, respectively, the foot sole acts a substantially uniform and coordinated distribution of forces. This is a first ground contact on slightly supinated heel instead. While the entire foot has contact with the ground, the main load increasingly shifts to the metatarsophalangeal joint before the new step is initiated over the big toe. According to the invention thus both the profile hardness and the tread depth is ergonomically adapted to the desired requirements.

Especially in combination with the set-back bale roll, a synergistic, efficient, energy-saving and less stressful walking and running is possible. It allows a natural rolling action with stable placement on the heel and rolling over the forefoot. Furthermore, the up and down as well as the stance phase is facilitated. Overall, lower fatigue and stress symptoms of the feet are the result. As a result, the overall movement is improved and a healthy gait and running picture is achieved.

According to one embodiment of the invention, the bale roll spacing may be at least 2 mm, preferably at least 3 mm, more preferably at least 5 mm, or at least 0.5%, preferably at least 1%, more preferably at least 1.5% of a sole length. Particularly suitable is a bale roll spacing of about 5 mm has been found. The bale roll spacing may be at most 10 mm, preferably at most 7 mm or at most 2.5%, preferably at most 1.7% of a sole length, measured along the longitudinal center axis.

The bale roll can, at least in certain areas, run at a predetermined, oblique angle with respect to a longitudinal center axis, in particular following the natural course of the bale. This can further improve the ergonomics while walking.

According to one embodiment of the invention, the sole has a bowing of a forefoot area and / or an increased tip blasting of, for example, at least 10 mm, preferably at least 15 mm. In interaction, in particular with the set-back bale roller, a particularly energy-saving walking can thereby be made possible.

In a concrete embodiment, a midsole, in particular of ethylene vinyl acetate (EVA) and / or polyurethane (PU) is provided. Also a bale roll of the midsole may be located in a predetermined midsole-bale roll spacing behind the bale line. The midsole-bale roll distance may coincide with or be defined by the ball-roll spacing of the (total) sole. By such a measure, the step division is further improved and facilitates the rolling of the foot. The (cushioning) material of the midsole, especially EVA or PU, can be adjusted harder or softer depending on the application.

Preferably, the sole comprises a pronation support in a foot arch area. Also, this pronation support can, especially against the midsole harder, material, such as EVA or PU be formed and formed in terms of their shape and hardness to stabilize the arch of the foot. This improves the stability and sure-footedness when walking.

In a specific embodiment, the sole has a forefoot cushioning element. A degree of firmness of the forefoot cushioning element may be adjusted such that the step design flows and is not interrupted. The shape and nature of the forefoot cushioning element can be adjusted in such a way that it is adapted to the foot anatomy or the natural appearance and relieves the pressure points. The forefoot cushioning element is preferably made of a harder material than the midsole or the other components of the midsole.

Furthermore, at least one heel cushioning element may be provided in a heel region whose material, for example EVA or PU, is also preferably made harder than the material of the midsole. The heel cushioning element (heel wedge) can be designed such that it absorbs the initial impact and initiates the rolling movement. This optimally protects the joints and optimizes the rolling motion. Overall, forefoot cushioning, heel cushioning and torsional stabilizer further enhance ergonomics while running.

Furthermore, the outsole in its rear region facing the heel, in particular a plate or rod-shaped, reinforcement of a torsionally and bending resistant material, preferably made of plastic or metal, have. Such an element is a torsion stabilizer, which is also preferably made of a harder material than the material of the midsole. The torsion stabilizer is provided in a metatarsal area and serves as a metatarsal bridge and increases the stability of the torsional movement, so that it advantageously prevents a rotation of the forefoot to the heel during the rolling movement.

Preferably, the sole comprises a heel bevel, wherein a front edge closer to the forefoot portion of the chamfer at its inner end, relative to the outer end, is offset back towards the rear.

According to a further embodiment of the invention, a shoe inner is substantially seamless, wherein in particular portions in the shoe interior, which adjoin a foot, are seamless. Furthermore, the shoe according to the invention advantageously has a soft shaft edge and, as desired, in particular in the forefoot and / or toe region, a soft, yielding front cap, so that according to the invention all sections and parts of the shoe which are attached to a foot, an ankle and / or a lower leg adjacent soft, yielding and are formed without bumps or openings, so that neither in the shoe itself nor at the shaft edge in use pressure points occur, which could lead to adverse irritation of the skin or tissue, especially in persons with skin and / or circulation problems. By ensuring such a soft and resilient shoe interior and soft sheep's edge of the shoe according to the invention for persons with skin and / or circulation problems, for example, for diabetics, particularly well suited.

Furthermore, according to a preferred embodiment of the invention, the shoe according to the invention has a removable insole in the form of a padded sole, which preferably has a pressure peak reduction, in particular in the ball area. The insole insertable into the shoe according to the invention has a thickness in the range of 3 mm to 15 mm, preferably in the range of 6 mm to 12 mm and particularly preferably in the range of 7 mm to 10 mm. This insole, which, as mentioned above can also be designed as a sole, is made in this case of a soft and resilient material, so that no pressure points and / or pressure peaks can emanate from this insole when using the shoe. Furthermore, it should be noted that the insole is inventively designed so that it is removable and can be replaced by custom-made Maß- and / or model inserts, by which the foot of a wearer can be supported individually.

Furthermore, the shoe according to the invention may have a leg edge that is substantially raised by the height of the pad sole and / or a forefoot area and a metatarsal area bounded at the rear by the ball line, so that an inner volume of the forefoot area compared to a shoe with a conventional insole whose height is typically less than 3 mm is increased by a range of 7% to 15%, preferably 9% to 13%. In this way, the shoe according to the invention can be particularly advantageously provided with custom-made Maß- and / or model inserts, which are generally designed significantly higher than conventional shoe insoles, without the shoe inner volume is thereby uncomfortably reduced and / or the heel area is raised so far that on rear shank edge of a shoe pressure points would occur. The shoe according to the invention thus has an interior space which, even with the use of special inserts adapted to one foot, has sufficient internal volume in order to reliably exclude the occurrence of pressure points both downwards and upwards and towards the sides, so that damage to one located in the shoe according to the invention foot is certainly counteracted.

Incidentally, it should be noted that the bale roll is offset rearwardly toward a heel end relative to the ball line in the shoe of the present invention, this offset arrangement being substantially parallel to the bale line and extending from an inner ball point to an outer ball point. the outer edge of the outsole surrounding the forefoot defines a first wrapper having a first length, a second wrapper following the peripheral edge of the outsole surrounding the forefoot and having its start and end points associated with respective opposite ends of the staggered bale roll second length, the second length having a range of 9% to 14%, preferably a range of 9.8% to 12.5%, of greater length than the first length. The extent to which the bale roll is offset towards the heel end relative to the ball line in a shoe according to the invention is thus oriented to the peripheral edge of the outsole surrounding the forefoot, the respective length of the respective wrap being on the one hand at the respective opposite points of the ball line and, in the case of the rearwardly offset bale roll, at the respective opposite end points of the bale roll.

Further embodiments emerge from the subclaims.

The invention will also be described in terms of further features and advantages based on embodiments, which are explained in more detail with reference to the drawings.

Hereby show:

1 a schematic representation of a sole for a running shoe according to the invention in an exploded view including a last for the production of the sole; and

2 a sole for a running shoe according to the invention in a view from below (partially in exploded view).

In the following description, the same reference numerals are used for the same and like parts.

1 shows a schematic representation of a sole 10 for a running shoe according to the invention in exploded view and a last 11 for the production of the same. The last 11 includes a recessed ingot roll 12 and is characterized by a bend 13 as well as a comparatively high top blasting 14 of for example at least 10 mm. The inguinal roll 12 defines, at least in part, the bale roll during manufacture 38 the sole 10 , as well as 2 can be seen. The bale roll of the sole 10 After production, it is about 5 mm behind the natural bale position.

The sole 10 includes an insole 15 , a midsole 16 , a torsion stabilizer 17 , a heel wedge 18 as heel cushioning as well as an outsole 19 with a profiling. About the insole 15 The hardness and flexibility of the shoe can be at least partially adjusted and thus the application of the shoe can be defined. In this case, a gestrobelte embodiment with a comparatively soft textile insole provide high flexibility. According to a preferred alternative according to the invention, however, the insole is glued, namely in particular with a shaft edge at the top of the outsole. A hard insole promotes stability while running and also allows a well-defined, especially uniform, distribution of forces and surface loading.

In the midsole 16 is a forefoot cushioning 20 and a pronation support 21 integrated. Both the forefoot cushioning 20 as well as the pronation support 21 are made of a material that is harder than the other components of the midsole 16 , Also a midsole bale roll 22 is set back to facilitate the rolling of the foot. The midsole bale roll is defined by a lower crest line of the midsole.

The pronation support 21 is in a foot arch area 23 on an inner edge 24 the midsole 16 arranged and promotes a pleasant pronation control or stabilization of the arch of the foot. In In the present embodiment, the pronation support 21 within a longitudinal center axis 40 and the inner edge 24 the midsole 16 arranged. The forefoot cushioning 20 is in a forefoot area 25 the midsole 16 arranged and formed in approximately kidney-shaped to relieve the pressure points.

The sole 10 is subdivided below in two different ways: on the one hand in the forefoot area 25 and in a hindfoot area 42 , These two areas are separated by the ball line. On the other hand, the anatomy is subdivided into the tarsal area 28 , Midfoot area 29 and toe area 30 performed. The ball line 37 is located within the midfoot area 29 ,

The midsole 16 is, if desired, in the shoe below the insole 15 arranged. Below the midsole 16 are the plate-shaped torsion stabilizer 17 and the heel wedge 18 , respectively the heel cushion, arranged. The heel wedge can absorb the onset of impact and initiate the rolling motion, so that the joints are better protected and the rolling motion is improved. The heel wedge 18 is wedge-shaped and widens in the direction of a heel end 26 the sole 10 , The torsion stabilizer 17 is in the arch area 23 provided and can reduce or prevent the rotation of the forefoot to the heel in a rolling motion. Below torsion stabilizer 17 and heel wedge 18 is the outsole 19 arranged. A profiling 27 (see also 2 ) is adapted to the natural gait pattern of humans and follows the S-shaped rolling line. The first contact with the ground may take place on a slightly supinated heel. Furthermore, the profile hardness and tread depth of the sole of the shoe according to the invention can be adapted to the different requirements.

In 2 is a view on the sole 10 shown from below. The outsole 19 is here in a tarsal area 28 , a midfoot area 29 as well as a toe area 30 subdivided. An inner tarsal area edge section 31 is here softer than an outer tarsal area edge portion 32 , Furthermore, there is an inner metatarsal edge portion 33 harder than an outer metatarsal edge portion 34 , An inner toe area edge portion 35 is also harder than an outer toe edge portion 36 ,

Furthermore, in 2 a ball line 37 represented, opposite to a bale roll 38 to the rear around a bale roll distance 41 is offset, as by the ingot roll 12 and the midsole bale roll 22 specified. The thus defined bale roll 38 is in the present example by 5 mm from the ball line 37 back towards the heel end 26 added.

The sole includes a heel slope 44 wherein a boundary line closer to the forefoot area 43 is offset backwards at its inner end.

The sole 10 can be constructed in the sense of a modular system. In particular, a set of a plurality of strips and / or insoles and / or midsoles and / or torsion stabilizers and / or heel wedges and / or outsoles may be provided. In this case, all elements in hardness, material design and shape can be adjusted individually and therefore the sole to different needs and functions, in particular to the needs of people with skin and / or circulation problems, especially feet, such as diabetics adapted. Thus, the area of use of the sole advantageously increases significantly.

In 2 is the course of the first envelope 45 around the peripheral edge of the outsole surrounding the forefoot. The second envelope, also shown schematically 46 is longer than the first envelope 45 , The first envelope 45 extends from the opposite ends of the ball line 37 around the peripheral edge of the outsole associated with the forefoot, while the second envelope 46 each from the opposite ends of the bale roll 38 extends around the circumferential edge of the outsole surrounding the forefoot. In the following table, the last volume, the length and the width and the position of the bale roll of the shoe according to the invention are compared to the corresponding dimensions and the ball line of a conventional shoe, wherein it is clear that the second envelope 46 that of the recessed bale rolls 38 associated with a shoe according to the invention, longer than the first envelope 45 is that associated with a conventional shoe.

It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
