Such a shoe configured according to the invention can achieve a physiologically effective and correct rolling motion (flexing motion) by the placement of the sole body in the back heel region, and subsequent rolling off via the physiological guide body in the form of the hollow body (4c), toward the front ball/toe region (1c), particularly in the direction of the big toe.

Description

The invention relates to a shoe having a sole body extending from the heel area over the midfoot area to the front ball and toe area and upper material attached thereto.

State of the art

In EP 999 764 a shoe is described which has a sole extending from the heel area to the ball-toe area, which sole is formed by a sole body and a sole covering arranged on the underside of the sole body. Furthermore, a recess extending approximately from the midfoot region to the heel region is provided, which is provided between the sole body and the sole covering. In this case, the region of the sole region assigned to the recess forms a pivoting element, which is pivotable about an axis which is arranged in the end region of the recess facing the midfoot region. In the recess at least one approximately wedge-shaped or circular segment-shaped material element of resilient, soft material is arranged. The foldable sole covering is designed to be flexible in the area of the pivot axis and / or has a taper in this area.

A disadvantage of the known shoe has been found that the wear and wear are relatively large by the constant pivotal movement of a portion of the sole covering about the axis in the metatarsal region and thus this is a weak point of this shoe. This is also not surprising, since just this area in which the pivot axis of the sole covering is at every step is particularly stressed. Namely, at each step, the sole pad is first placed in the heel area; then the shoe is unrolled in and over the midfoot region, which takes place in particular in the region of the pivot axis of the flexibly formed sole region.

In one embodiment of the known shoe, the approximately wedge-shaped, lenticular and / or approximately circular section-shaped recess is filled with resilient foam material, by which a relief of the foot and / or knee joint is effected. The foam material will become brittle over time due to the high levels of continuous stress, is sensitive to mechanical influences and absorbs any type of fluid, with the result that this foam material must be taken out in time-consuming work and replaced with new damping material.

A multilayer insole is out EP1702593 A and US-B1-6247250 known.

Presentation of the invention

The object of the invention is therefore to design a shoe so that occurring during walking / running shock loads are not or only to a very limited extent on the knee, hip joints and spine and at the same time a physiologically correct rolling motion is obtained.

According to the invention, this object is solved by the features of claims 1, 11 and 12. Advantageous developments are the subject of dependent claims.

According to the invention, the object in a shoe according to the preamble of claim 1 is achieved by arranging on the sole body one above the other a first thin insole with a running trough formed in the midfoot region with depression, one of the heel area to the front ball-toe area continuous foam pad with a size of the tread corresponding neck and a second insole in the form of a footbed with one of the sole bottom in the midfoot area above, the trough recess adapted spherical segment or ellipsoidsegementförmigen hollow body are provided.

In a shoe designed according to the invention, in which the two insoles and the foam pad are provided therebetween, a physiologically correct rolling movement thus takes place, for example starting from the outer crotch in the rear heel area of the respective shoe via the midfoot area to the ball area and the big toe Form of a flexing movement takes place. Here, the sensitive foam pad between the two insoles is protected not only from mechanical influences, but also from moisture. The wearer of such a running shoe perceives from the outside a known image of a shoe. This gives the wearer of this shoe the feeling of security. No one sees the wearer of a shoe according to the invention that it is a so-called "balance" shoe.

Due to the above-described operation, the impact load on the sensitive foot and knee joints as well as on the spine when walking and standing is substantially reduced. Furthermore, a wearer of a shoe designed according to the invention is brought into a physiological basic posture, in particular when standing, in which the knees are slightly angled. As a result, when standing next to the knees and the spine is relieved; At the same time the posture in the area of the wearer's upper body is improved. This is achieved by the physiologically correct posture when walking and standing, as this activates the muscles in a natural way again and thus relieves the joints as a kind of natural shock absorber.

In order to promote the sinking in the heel area, according to an advantageous embodiment of the invention, the foam pad in the heel area on the underside a deep recess. In addition, according to the invention, a flat recess is also formed in the front ball-toe area on the underside, so that the correct physiological rolling-off process is additionally supported by the two lower-side recesses in the foam support.

This is caused by the fact that, unlike normal shoes, the heel sinks when putting on the ground, often hard asphalt, the heel area strongly; This will bend the knee slightly, raise the upper body and activate the muscles, before a shock-like impact on the body occurs. The musculature thus absorbs a large part of the shock load, whereby the joints are greatly relieved. After sinking in the heel area, the foot then rolls softly over the midfoot area.

Here, the two insoles made of wear-resistant, abrasion-resistant material, such as carbon fiber reinforced material, hard plastic, hard rubber, metal or similar material with appropriate properties and the interposed foam pad for distributed over the entire foot pressure distribution. The load on the foot and on the joints occurs only after sinking in the heel area during the rolling process.

Further positive effects of the altered gait and the altered posture during walking and walking are the following: In flat, kinking and lowering feet or pronounced pronation, a "stimulus" is exerted with every step, especially in the area of plantar aponeuroses (longitudinal fiber tracts). This, in turn, can cause the arch of the foot to rise again if the pronation or flat feet are more pronounced.

In addition, all muscles around the ankle and foot flexors are trained; This in turn has the consequence that the circulation of the venous musculature is ensured, which is important, for example, especially in varicose veins. The lymph flow is also stimulated by the rocking in the shoe, slag substances are better eliminated.

Thus, no pressure is exerted in the region of the tread and there provided ball segment or ellipsoid segment-shaped hollow body on the metatarsus, a damping element, for example in the form of foam material is provided in the hollow body. In order to secure the damping foam material in the hollow body, a thin pad of leather or a leather-like material is applied to the top of the second insole.

According to an advantageous embodiment of the invention is for supporting and promoting the physiologically correct rolling movement on the one hand in the heel of the second insole from the outer edge forward at an acute angle to the shoe longitudinal axis at least one slot introduced and on the other hand are in the ball-toe area of the second insole, starting from the sole outer edge forward at an acute angle to the shoe's longitudinal axis at least one slot and At least two slots are made starting from the sole inside edge at an acute angle to the longitudinal axis of the shoe. Through these slots, a kind of leadership is achieved together with the cup-shaped design of the second insole, whereby the physiological effect is additionally promoted.

The above-described advantageous developments of the shoe with regard to a physiologically correct rolling movement in the manner of a flexing movement apply in particular to street shoes. In order to achieve an adaptation for shoes used in the field of sports, the second insole can be designed so that it is pulled up in the heel area according to a ball heel.

The above-described measures and developments of the shoe according to the invention can also be achieved if the first thin insole and the second insole are reversed in their execution. In this case, in the first on the sole body of the shoe arranged thin insole integrated in the midfoot area of the sole top protruding spherical segment or ellipsoidsegmentförmiger hollow body, while in the second designed in the form of a footbed insole from the sole bottom in the midfoot region projecting running trough is integrated which in turn has a recess corresponding to the spherical segment or ellipsoid segment-shaped hollow body.

In a further embodiment of the shoe according to the invention, the first thin insole has a built-in tread in the midfoot area with a truncated cone-like depression. Accordingly, the second in the form of a Footbed shaped insole has one of the sole underside protruding, the depression in the trough corresponding hollow body, in which a frusto-conical portion merges into a spherical segment-shaped portion.

In the case of knee osteoarthritis and other forms of joint problems, the above-described embodiments of the shoe according to the invention result in enormous relief simply because the statics change. The wearer of a shoe designed according to the invention stands upright and walks and stands more in the "middle"; This in turn is also of great importance for malpositions, such as O-legs (Genu varum) or X-legs (Genu valgum).

Also helpful for this effect is the fact that the shoe according to the invention is also laterally stable. ("Balance" effect) As a result, the wearer / user of the shoe additionally has to train (or train) the foot muscles and thus prevents the tendency to pronate or subinject.

Active walking and the resulting physiologically correct rolling motion activate muscles, such as the gluteus maximus, medius and minimus muscles, which is of particular importance for supporting the lower back muscles and stabilizing the pelvis. The spiral dynamics, which go up from the foot, the whole trunk is trained again.

The back muscles are involved in walking as well as the abdominal muscles again. In a sense, you change from passive to active walking. Man learns the conscious again Walking, including the natural active arm pendulum, which activates the shoulder and upper back muscles; Tensions are released.

Description of the invention

In the Fig.1 to Fig.5 are identical or similar components of a shoe according to the invention designated by the same reference numerals. The shoe according to the present invention comprises a continuous sole body 1 and an upper material 11 connected thereto, which has a sole-in Fig.1 indicated by dashed lines - surrounds foot 12 of a wearer. The upper 11 may in the usual way, for example by means of laces, Velcro or dergl. be closed. The sole body 1 extends from a rear heel region 1a over an adjoining midfoot region 1b to a front ball-toe region 1c; In this case, each of these three areas 1a to 1c extends in about more than a third of the shoe length.

On the underside of the sole body 1, a not shown in the figures Sohlenbelag is provided, which consists of an abrasion-resistant material, such as hard rubber and can be profiled profiled on its underside.

On the sole body 1, a first thin insole 2 is arranged, in which in the midfoot portion 1b, a trough 2a is integrated, in which one of the shape of a - hereinafter described in detail - hollow body corresponding recess 2b is formed. (See also Figure 3 )

As Fig.1 and 2 can be seen, is arranged on the first thin insole 2 from the heel area 1a over the midfoot area 1b to the ball-toe area 1c continuous foam pad 3. As Fig.1 and 4 can be seen, one of the size of the integrated into the first insole 2 running trough 2a corresponding cutout 3a is provided.

The foam pad 3 is made of resilient material and has, as the sectional view of Fig.1 and the representation in Figure 4 can be seen, in the heel region 1a on the underside a deep recess 3b and in the front ball-toe area 1c, a further relatively shallow recess 3c.

Like also Fig.1 and 2 can be seen, a second insole 4 is provided on the foam pad 3, which is modeled in its execution of the shape of a footbed. In the second insole 4, an ellipsoid segment-shaped hollow body 4c protruding from the underside of the insole 4 and formed in the midfoot region 1b is integrated, on the shape of which the depression 2b of the tread 2a is adapted. The hollow body 4c may also be formed in the shape of a spherical segment, for example, hemispherical or in a similar shape.

Both the thin first insole 2 and the slightly thicker second insole 4 are made of a wear-resistant abrasion-resistant material, such as carbon fiber reinforced material, to some extent elastic hard plastic or elastic hard rubber, an elastically deformable metal or similar material with corresponding properties.

The in sectional view ( Fig.1 ) as well as in side view ( Fig.2 ) reproduced second insole 4 is provided in particular for street shoes. In contrast to this, the in Fig.1 represented by a thick dashed line embodiment of the second insole 4 in particular provided for sports shoes. For this reason, the rear part of the second insole 4 is formed corresponding to the ball heel of the human foot and raised accordingly.

Like the side view in Fig.2 and in particular the plan view in FIG Figure 5 can be seen, in the second insole 4 in the heel area 1a at least one slot 7 and in the ball-toe area 1c slots 8 and 9 are formed. As Figure 5 can be seen, the slot 7 extends from the sole outer edge in the heel region 1a forward, ie in the direction of the midfoot region 1b at an acute angle relative to the dash-dotted registered shoe center axis 10. The slot 8 extends from the sole outer edge in the ball area 1c of the second insole 4th pointing to the front, pointing to the toe area, also at an acute angle to the shoe longitudinal axis 10, while the other two slots 9 in the ball-toe area 1c starting from the sole inside edge in the ball area 1c to the midfoot area 1b to the rear, ie at an acute angle to the shoe longitudinal axis 10 in the direction of the heel area 1a run.

As already stated, in order to prevent pressure being exerted on the midfoot in the region of the tread and the spherical segment or ellipsoid segment-shaped hollow body provided there, a damping element, for example in the form of foam material, may be provided in the hollow body 4c according to a preferred embodiment of the invention , In order to secure the cushioning foam material in the hollow body, a thin support made of leather or a leather-like material is applied to the top of the second insole 4, but this is not shown separately in the drawings in detail.

When walking or walking the sole body 1 of the shoe is first placed in the heel area 1a on the ground. Here, by the foot 12, the rear part in the heel region 1a of the foam pad 3, in which on the underside the relatively deep recess 3b is formed, compressed. Subsequently, the foot 12 is provided in the form of the ellipsoid segment-shaped hollow body 4 c, for example, in the form of the ellipsoid segment-shaped hollow body 4 c in the middle foot region 1 b unrolled the way that when striking the sole body on the ground by the foot 12 in the front ball-toe area 1c, the elastically deformable running second insole is pressed down. As a result, in turn, in the ball-toe area 1c, in which the flat recess 3c is formed on the underside of the foam pad 3, the foam pad 3 is compressed to different degrees, in the region of the big toe slightly more than in the other four toes.

In the above-described unrolling operation of placing the shoe or the sole body 1 in the rear heel region 1a, the unrolling of the foot 12 in the midfoot region 1b via the physiologically important guide body in the form of the ellipsoidal segment-shaped hollow body 4c in the described example until placement in the front ball-toe region 1c , especially the big toe, is a very soft, joint-gentle running and thus realized a physiologically correct rolling motion.

Due to the example ellipsoidsegmentförmig formed underside of the integrated into the second insole 4 hollow body 4c and a physiologically correct posture when walking and standing is achieved. At the same time, the muscles are activated in a natural way, whereby, above all, the muscles are integrated, which ensures that the foot does not bend right or left perpendicular to the running movement. In this way, the sense of balance of the shoe wearer is improved or positively influenced.
