Abstract

The device has a supporting projection (5) in the area of the middle foot (6), particularly in the area of the heel bone or the navicular bone or anklebone. The projection runs rounded, essentially transverse to the sole and forms a border of portion of the middle foot and load bearing capacity, particularly over the heel bone or the navicular bone or sphenoid bone or the anklebone. The border is half-shell shaped, particularly in terms of a high-standing arm or of two limbs. Independent claims are included for the following: (1) a method for manufacturing a device for inserting in a shoe; and (2) a shoe has a lateral reinforcement.

Description

The invention relates to a device for insertion into a shoe according to the preamble of claim 1 and a method for producing a device for insertion into a shoe according to the preamble of claim 12 and a shoe according to the preamble of claim 14.

The foot is complex and, due to its stabilizing function for the body, particularly when using very high-heeled shoes, so-called high-heels, heavily stressed. Through the longitudinal vault and a transverse arch, the body weight is mainly supported by the three points heel, big toe joint and small toe ground joint. Many foot diseases are based on a fall in the arch of the foot, which is particularly demanding in the high heel. The body weight of the sole of the foot is carried to different proportions, whereby it accounts for about 33% on flat heels, the ball of the foot is about 40% loaded and the rest on the outer edge of the foot about 15%, the big toe about 5% and the remaining toes is about 7%. In contrast, high heels cause a strong change in weight distribution between forefoot and hindfoot, so that the bale area is much stronger and thus unnaturally loaded.

Conventional insoles are inserted as partial inserts in the foot ball area of the high-heel shoe and are equipped, for example, with a padding of gel or foam.

The disadvantage here is that - in addition to the fact that the same high percentage of body weight still rests on the bale - especially the ball area of high heels for the wearer is narrower and thus creates an additional pressure on the bale and a callus formation takes place, in particular with prolonged use of the shoes.

Object of the present invention is to provide a safe, reliable and relieving device for insertion into a shoe with paragraph, especially a high-heel.

To solve the problem is proposed, a device for insertion into a shoe with a high heel, especially in a high-heel shoe, in the form of at least the sole of the foot at least partially covering insert with a trained, supporting projection in the region of the metatarsus, in particular in the region of the heel bone and / or the scaphoid bone and / or the coccyx and / or the anklebone, which extends substantially transversely to the sole of the foot, and an enclosure of at least part of the metatarsus and a load suspension, in particular via heel bone and / or scaphoidal bone and / or cuneiform bones and / or the ankle.

For shoes with a high heel, especially high-heels, keeps the insert thus reinforced the foot on the heel so that the foot does not slide forward and thus down through the front beating invention. As a result, the main burden is taken from the forefoot and the balls of the balls and the pressure is released by relieving the forefoot on the heel and metatarsals. By insert according to the invention, the heel is supported in the metatarsus in the sense of a metatarsal. The load is absorbed by the heel bone, navicular bone, and cuneiform limbs, which are bordered in particular in the form of a half shell. The high-heel insert is a midfoot insert which has little to do with shape and cut with the usual orthopedic insoles. The insert can be fitted into any women's shoe with a heel without narrowing the foot. This is done particularly advantageously by the use of thermoplastic materials which can be adapted under heat to different heel heights, for example, Plexidur can be used.

Advantageously, one can equip the heel-corresponding part of the insert with an angle lever, in particular a notch of the insert in the sense of a clamp for controlling the heel.

Since the device preferably has no lateral guides in the middle metatarsal region, the forefoot can erect and position itself by the weight-relief, without creating a lack of space in the shoe. The insert greatly increases the pressure distribution and support of the foot, greatly reducing deformities and injury risks. Diseases such as hammer toes hallux valgus, hallux rigus, splayfoot, blisters and calluses, etc. are reduced or even completely avoided.

It is particularly advantageous if the enclosure is in the form of a half shell, in particular in the area of the heel, in particular in the sense of an upstanding flap and / or two wings. In particular, the flap acts as a lateral grip on the heel and allows some sort of leverage to better control the shoe on the heel. On the inside, two wings can preferably be arranged, which allow, for example, by means of a thermoplastic material adaptation, a slight adaptation to the foot shape. The height of the wings and / or the flap can be designed differently depending on the need for stability.

It is particularly advantageous if the enclosure holds stirrup-like. The midfoot insert works thus in the form that the foot is symbolically held as in an anatomically shaped stirrup, so that a forward-slip is prevented.

It is advantageous if an insert is laterally applied in a region behind the bump of the fifth metatarsal bone, which is shaped with a predetermined upward pitch at the top. Lateral is thus - similar to known childlike Knickfußeinlagen - an application, especially in the form of a flap, especially behind the increase in the metatarsal area created. The fifth metatarsal bone is thus lying freely but taken directly behind it, so not under pressure but held.

This insert is advantageous to shape steeper back up, because of the purpose in shoes with paragraph. Slipping forward to the bottom and an evasion laterally, ie laterally, is prevented. Now, a medial Längsgewölbeaufrichtung done by a Supination, which means a lifting and a cup-shaped support of the medial metatarsus.

Advantageously, the insert comprises thermoplastic material, in particular completely or partially transparent. Proposed is a design of the insert with partially or completely transparent thermoplastic.

Advantageously, the insert comprises a transparent plastic. Thus, the deposit is not noticeable and can be worn to different, especially half or completely open shoes. In closed shoes, non-transparent materials can also be used.

Advantageously, the insert fiber composites, in particular with glass and / or carbon and / or leather and / or foams and / or gels and / or plastics, such as silicones and / or polyurethane and aluminum and / or non-ferrous and precious metals. All forms of fiber composites (glass-carbon leather, etc.) can be used, or foams, gels and silicone, polyurethane, which can meet the physiological requirements.

Advantageously, the insert comprises partially elastic materials, for suspension and support of the arch and / or in the insert a heel buffer in particular comprising: gel /, in particular Technogel and / or polyurethane and / or air cushion. Partial elastic materials are useful to ensure shock absorption, for example, this can be supplemented by various types of metals are used.

Advantageously, the insert is finally covered with a padding material to ensure good shock absorption. A cushioning and better wearing comfort are guaranteed.

Advantageously, the insert is permanently or temporarily attached to the shoe by means of a bottom attachment, in particular by double-sided adhesive films, Velcro fasteners or micro-Velcro, is fastened substantially centrally and / or in the forefoot area. The attachment of the insert in the shoe can be made on a variety of forms. Fixed gluing / double-sided adhesive films, Velcro or micro-Velcro. The gluing the forefoot tip but also sufficient to prevent slipping. The change of the deposit in other shoes is thus easily possible.

It is advantageous if the device is integrated in a shoe, in particular in the shoe sole, so that in particular the sole and the insert are made of the same material.

The object is also achieved by a method for producing a device for insertion into a shoe, wherein an insert is formed with a projection in the region of the metatarsus adapted to the slope of a shoe with paragraph, in particular for forming a device according to one of claims 1 to 11th

It is advantageous if in the manufacturing process an impression of the foot is made to prepare the device, wherein at the position corresponding to a projection, an element for positioning the foot is provided in the mold.

The production can be carried out in particular via the production of a plaster cast in the sense of a special and / or custom-made, wherein the paragraph slope is provided and also an adapted projection corresponding element in terms of the shell shape or stirrup shape is provided so that the foot already at production the impression is kept in the correct position and under the appropriate weight of the body. The plaster cast then allows duplication.

The object is also achieved by a shoe with an integrated device according to one of claims 1 to 11.

Advantageously, the shoe has a boot shape and a lateral reinforcement on the insert, which extends preferably over the ankle out to the lower leg.
