shoe

The invention relates to improvements in shoes.

For constructive reasons, foot health has been sacrificed to a certain degree to modern shoe style. For example, those who wear the shoes feel the lack of width in the area of the toes which, if left long enough, causes the toes to be compressed so that the first, fourth and fifth toes are less needed than without shoes would be the case. This causes these toes to gradually become soft and bent. In order to compensate for this exhaustion, the toes turn outwards when walking, and this causes them to roll over the inner arch of the foot. Just as this tendency causes certain muscles to be used less, it also causes increased toe deformation, which in turn causes a consequent distribution of weight that causes unusual tension in the inner longitudinal arch of the foot, which gradually changes the structure of the foot, and as a result from this, the performance of the feet is reduced and posture damage occurs in other parts of the body. It is well known that in almost all shoes certain muscles are weakened, the bones are bent and the toes are bent

109819 / O3S3

become and the toes cramp, so that especially the first, fourth and fifth toes often no longer related to each other can be braced to increase the width of the front part of the foot. In contrast, the toes are trailing Curved against each other on the inside, which results in an even lowering, results in fatigue and a substantial reduction in the effective weight distribution of the foot. Since children those in whom the bones are soft and the muscles can be easily distorted, often wearing shoes, will damage in the foot structure that can no longer be removed.

The invention creates a shoe for a human foot, which consists of an upper part - the so-called Shank - and a sole part, which together form an inner cavity for receiving the foot, the simulated Void like a last in its plan view in the area corresponding to the inner arch of the foot, a straight one has inner edge; at this part corresponding to the area of the cavity which receives the toes, a has outer and inner edges that diverge towards the toes of the last; a planar sub-surface of the area corresponding to the big toe to the area corresponding to the front end of the calcaneus contains a has the instep corresponding upper surface, which has its maximum height in a plane parallel to the inner Reached edge that is much closer to the inner edge than to the outer edge of the foot; a stool at the has upper surface in the area of the outer Kt and corresponding to the area of the cusp of the fifth metatarsal runs to the lower surface.

Such a shoe combines the basic features that

109819/0353

illustrated in U.S. Patent 2,6o7,132, in addition but the cavity within the shoe delimits the feet more precisely in their natural posture. The top of the The instep is not deformed by pressure on either side of the naturally deepest part of the foot pressed and the muscles below the instep of the foot are exposed to develop.

The inner part of the heel support area of the sole surface can be raised, since, typically, when weakened Feet the inner edges of the heels slope down and the outer edges of the soles of the shoes slope up, which has the consequence that the weight flow when walking is supported, forward in a longer axis along the inner heel and the outer arch of the foot and through the Toes and not through the arch of the foot.

On the upper surface of the sole can be in the area below the fourth and fifth toes a raised part may be provided in order to straighten the toes, which are caused by shoes, which did not allow these toes to assume a normal width position, have become deformed. The elevation of the fourth and the fifth toe gives those toes an opportunity

a) for increased leverage when walking,

b) for contact with the sole to support balance while walking

c) for contact with the sole to support balance when standing and

d) for total weight support to practice the same.

^{A part that rises up in between can be pre-v} -n on the upper surface of the sole in a region of the outer arch of the foot in order to provide greater weight support on the stool

109819/0353

in the area of the fifth metatarsal and adjacent areas. The outer arch surface in people without shoes has a denser layer of muscles than in people with shoes, in which the layer fills a convex arch of the foot and has a weight-bearing function through the outer arch bones, even on smooth surfaces such as roads. However, in humans, W which are usually without shoes lack this G-ewichtabstützen, thereby the force is concentrated on the outer gewichtabstützenden areas of the foot and reduces the G-ize of the weight-distributing surface. In this way, the outer, arched, weight-supporting, raised part of the sole, designed as a base, enables the sole surfaces of the cusp of the fifth metatarsal area to be used as a weight-supporting part on a shoe that is adapted to the person, by causing this foot area to riding on the raised part instead of being useless and supporting little or no load on that part of the shoe.

Increased flexibility of the inner arch part of the shoe can be achieved by transverse corrugations. In order to give the muscles on the inner arch of the foot more opportunity to develop, the last on the inner arch of the foot is not hollowed out, as is the case with conventional lasts. In addition, a fixed joint in the shoe, which is particularly attached to the creation of greater strength of the normally weight-supporting outer arch of the foot in relation to the normally non-weight-supporting inner arch of the foot, will incline from the center of the front part of the heel area in a lateral direction away from the flexible, corrugated structure, to lie under the outer area of the foot and from the heel to a point behind BAD GRIGiNAL

Figure.1o feet without shoes in a posture as they are when standing or walking with the Weight flow is taken through the longitudinal axis of the foot; and

Figure 11 feet without shoes with an attitude at that the weight flow runs over the inner arch of the foot and not over the longitudinal axis of the foot »

To make the following paragraphs easier to understand, certain bones of the foot are named in the drawing by their names been designated. On this occasion it should also be pointed out that even normal feet are very different Have sizes and shapes, but all have common anatomical and physiological features, in particular the basic weight bearing areas, the heel, the outer side of the foot, the ball of the foot and most of the soles of the toes.

A human foot is illustrated in its natural position in Figure 1, from which it can be seen, that the The area of the inner arch of the foot in plan view is relatively straight that the area of the toes is in the direction of enlarged on the toes and that a bump can be seen on the outside, this bump being part of the fifth Metatarsal. The instep of the foot is much closer to the inside of the foot than to the Outside.

Conventional shoes are manufactured on a last having the shape of the plan view of FIG. 2 With this last no precautions are taken, the natural divergence in the area of the toes of the foot

109819/0353

still to be considered is the stool of the fifth metatarsal has been taken into account. In addition, the instep is not in the best position and its lower surface is generally rounded, as a result of which the space of the shoe is reduced, as in FIG. 9 as hatching 96 is illustrated.

A last for producing a shoe according to the invention "can have the shape of Figures 3 and 8. It can be seen from these figures that the sides of the toe area 99 diverge in that the last has an enlarged width at its front part, the instep is correct coincides with the natural posture of the instep and a stool is provided to correspond to the hump of the fifth metatarsal. The lower surface is usually planar from side to side between the area of the underside of the articulation between the metatarsal and the limbs and the anterior area of the calcaneus, this surface is designated by the 95th It is still to emphasize here that the surface of the last ren in the inne- * and outer Fußwölbungsbereichen is not hollowed out as is the case with conventional shoes, and is illustrated at 96 in FIG. 9 The delimitation of the lower surface is uniform over its periphery.

Such a shoe is illustrated in Figure 4 or 5, in which the reference numeral 11 generally designates a shoe having a toe region 12, a shaft opening 14, a Joint area 16, a heel area 18, a heel seat 2o and an outer sole 24. The figure's shoe is similar to that of the figure, only that the shoe of figure 5 a raised heel 22 and a supporting hinge 27. In FIG. 7, 23 is the outer arch area of the foot

109819/0353

of the last and the shoes, while 29 denotes the area of the inner arch of the foot and 25 the hump of the area of the fifth metatarsal. It can be seen that the side walls of the heel and heel seat are suitable for the heel «» of the wearer in the illustrated Posture to be snugly absorbed. Since the heel only consists of a single bone, the smeared

P same adjustment of the shoe in this area of the functioning of the various joints, bones and foot muscles not in the Y / ege. In the present invention, the heel seat is on the inner side of the heel with a lifting wedge 26, which is generally curved, as can be seen from the plan view, the edge 28 generally congruent with the seam line of the heel seat and the side winds of the heel upper of a foremost Point 34 is behind an imaginary transverse line 35 and behind the il-joint of the heel and cube bones up to the rearmost point on the longitudinal center line of the heel seat of the shoe. The front edge

. 3o of the heel ridge runs transversely inwards and towards the top on the center line of the shoe at a distance that is straight is less than half the width of the G-joint. At the innermost point it curves backwards and steps back a little, which means that it is in the direction of the side wall of the heel upper curves to form an inner edge 36 to the point of maximum receding where it is is again curved inwards, as illustrated by 37 is to bend around the rear part of the Ferpe, where it is then in the above-mentioned rearmost point of the elevation at 39 passes over, we should also note, üai3 the level of elevation is raised with respect to the main plane of the heel seat, and that the ranu of the pad in the heel seat is inclined or beveled so that it overlaps into the surrounding heel surface. The higher part of the elevation is for it

BAD ORIGINAL 109 819/0353

arranged to gently support the inner side of the calcaneus and to bend it outwards. The inclined hand areas of the elevation are generally designated 44. _O inclined edges are at the edges of the survey, which adjoins the heel upper, not necessary and preferably the height of the protrusion is not smaller than o, 78 mm and not larger than 9.4 mm in shoes for adults be the criterion of this is However, this is the condition given by the wearer's feet and by his particular weight and size. In a constructive embodiment, the heel elevation can either be placed on the insole as a separate wedge or inserted under it. The effects achieved by such heel elevation can also be achieved through use in a special sole by including the elevation in the manufacture of the shoe with the help of suitable provisions made for the elevation in the last, or alternatively the elevation can be used as an insert between the upper and lower layers of an insole may be attached in a position illustrated in the drawings.

ü; ine toe elevation 51 for the fourth and fifth toes A and 'B. is also provided with the toe raised generally diagonally at an angle of about 30 ° to a transverse line 47, which would bisect the phalanx of the little toe, which is close to the torso, and which starts at a point 45. These Elevation abuts the outer front edge 52 ″ of the shoe without a transition. The edge of the toe elevation runs along the rearmost line 54 in front of the joint 56 between the fourth and fifth metatarsals and the phalanges of the toes and extends at an oblique angle with respect to the longitudinal center line of the shoe, which in FIG with respect to the same at an angle of about 30 ° up to

at a point 58 which is approximately two-fifths the distance of the toe area so that it is below the fourth toe. At this point 58 the curve curves Edge forward along a line 6o to the front of the shoe. The rear and inner edges 62 and are beveled or inclined so that the major surface of the elevation merges into the plane of the surrounding surface. In turn the height of the elevation of the main part of the upholstery is preferably at least 0.78 mm and not more than 9.4 mm for adult shoes, and this bump can be also used in the form of a separate sole, inserted as a cushion in the insole or under the insole or attached to the upper part of the same. As is the case with the heel pad, it can also be taken into account in the last, in which case suitable filler material should be built into the shoe. The front and outer edges of the elevation are also at the same height, butt directly without transition to the outer edge of the shoes and are not beveled, so that when the toes are inside the Spread the shoe apart, e.g. the little toe is at a uniform, raised height in every position it can accepts.

In addition, an area that rises in between is provided around the area of the cuboid bone, the cusp of the fifth metatarsal and buttocks and rays of the fourth and fifth metatarsals and to snuggle up to this, with this elevation just in front of the transverse line 35 and just behind the G-eler *: en between the fourth and fifth metatarsals and the limbs of the toes. This raised area directly triggers the transition the outer edges of the shoe and runs from there along the edge 74 to the outside. For shoes with the special

109819/0353

According to US Pat. No. 2,6o7,132, this fits into the nose 75 of the cusp of the fifth metatarsal. The entire length of this raised area on the outer side is at the same level and along the side of the shoe and also abuts it directly without a transition. The inner edge 76 of the intermediate elevation 72 inside the shoe, ie the edge that is closer to the side of the big toe of the shoe is skew ^v with a mitigating Ab or provided with an inclined hand 78 which similar to that of the toe or heel elevation is so that the edges do not indent into the skin, while the bevel at the front is elongated to define an area which corresponds to the inclination of the metatarsal ray from a line 73 which defines the front and top edges of region 72 represents, which is located approximately at half the total length of this raised area, as illustrated in the plan view, and this inclined part descends down to a transitional leading edge 8o. This type of execution ensures that the highest elevation is under the stool of the fifth metatarsal bone and in front of the outer part of the cuboid bone, which gradually descends in a slowly sloping plane to the transitioning, thin edge behind the joints between the fourth and fifth Metatarsal and toe phalanx falls off. This highest elevation preferably moves, as is the case with the heel and toe pad, between 0.78 mm and 9.4 mm, and can also be used as a separate sole, as a separate pad either placed on or under the insole be included as part of the same. Furthermore, this cushion can be contained in the shoe as a part of the same, in that the elevation is already taken into account in the last and a filling material or a sole material can be added in order to fill the resulting pocket.

It should be noted that the elevation for the heel in connection with the area rising in between the Heel is effectively housed in the heel seat, since the opposing parts of these bumps tend to have a Limit the neck between the raised parts, which causes the heel bone to be held firmly within the heel is.

The above-mentioned elevation and the special elevation in the area of the cusp of the fifth metatarsal can be made from a variety of suitable materials can be made, which are usually used for elevations of the inner Soles and shoes are used. However, it is important especially With regard to the elevation in the area of the cusp of the fifth metatarsal bone, that this cushion is made of flexible Material is made.

A suitable joint 29 is illustrated in FIG. The rearmost point of the joint is in the middle of the The joint of the shoe at a point which lies approximately behind a transverse line 35. From this point the curve bends Joint outwards and forwards so that it roughly bisects the crotch bone and extends from this bisection point curves further forward so that it lies roughly between the rays of the fourth and fifth metatarsals to end at a point well behind the head of the fifth metatarsal 94. The material of the joint can be steel, wood, plastic, or any other suitable supporting material.

The inner arch area of the foot is weakened in selected places, in order to achieve that the sole of the shoe is softer in this area by means of transverse corrugations, i.e. that high and

109819 / 035T

alternating deep ribs and depressions are provided, which run from the outer edge of the curved line, which in turn from the transverse line 35 to a point behind the joint between the first metatarsal and toe links and laterally transversely in an arched, in its middle at its widest arc in one dimension, which is not more than half the transverse dimension of the joint of the shoe goes out.

From this it can be seen that shoes for wearing are built according to the type described and illustrated will enable the wearer to walk with his feet in a posture illustrated in Figure 10 is, i.e. in which the weight is along the longitudinal axis of the foot, taking full advantage of the toes, the toe bones and the foot muscles that activate the toes, which is in contrast to the posture shown in Figure 11 is illustrated in which the weight in a traumatic and unmuscular way by rolling over the inner arch of the foot and running just over the end of the toe.
