Shoe, in particular sports shoe

The innovation relates to a shoe, in particular a sports shoe, with a shoe extending above ankle height Upper made of deformable material, e.g. leather, and with a flexible outsole.

Runners, such as soccer players, handball players, Track and field athletes etc. are at risk of twisting an ankle or trespassing when practicing their sport of the ankle joint very exposed. This twisting is very much feared because it often, depending on the intensity with which it occurs, tearing or tearing of the outer ligaments of the Ankle, so that an operation is necessary. The healing process after surgery requires Regularly putting on a foot cast for a period of at least three weeks, during the the athlete is not only deprived of all training opportunities, but also by the extensive shutdown the foot and calf muscles dwindle beyond the loss of training.

The object of the present innovation is to create a shoe, in particular a sports shoe, which after an injury caused by twisting the ankle joint, especially after an operation of the outer ligaments that makes wearing a foot plaster unnecessary and that the ability of the foot to move with the exception of the injured Ligaments not affected.

According to the innovation, this is achieved in that the shaft is assigned to the outer knuckle Side by at least one stiffening element running vertically between the upper edge of the shaft and the outsole is stiffened.

The stiffening element is so largely rigid that the shaft is assigned to the outer knuckle Side the ankle is stabilized to a great extent. This is especially true in combination with the self Shank lacing that also extends over the ankle, through which the shank tauts the foot includes, so that there is a strong support against an outward buckling. The remaining Shaft areas and the outsole are deformable in the usual way, so that the wearer of the shoe with the foot can perform the natural rolling process in which the overstrained by the twisting Outer ligaments at the ankle are not strained. The athlete can therefore already immediately after the operation perform all those movements with your foot that do not put strain on the outer ligaments. Only the latter are prevented or at least severely hindered by the external stiffening of the shaft. As a result, there is muscle wasting of the foot and

Calf muscles no longer show, at least to the extent that this is a regular consequence of a plaster cast is. In addition, as the healing process increases, the athlete can even regain his foot load more, so that in a certain sense a training effect can be achieved.

There are different designs for the stiffening element. An expedient embodiment provides, however, that two or more stiffening elements in the form of flat bars rigid material, e.g. made of hard plastic or metal, fixed to the shaft are connected. These flat bars can be arranged so that the outer malleolus between them and thus an immediate pressure effect on the ankle is avoided.

Sports shoes are already known in which a support attachment according to Art a cuff is provided which firmly surrounds the ankle for the purpose of preventing the dreaded twisting to prevent (DE-OS 26 06 800). The support attachment also contains stiffening elements, but they are not cause a stiffening of the shaft part assigned to the outer malleolus as a whole, but only represent a more or less local protection for the ankle from blows.

Further advantages and features of the present innovation emerge from the following description of a preferred exemplary embodiment based on the accompanying drawings and from v.-further subclaims.

In the drawing show:

Fig. 1 is a side view of the shoe or boot according to the innovation, and

Fig. 2 is a partial section along the line II-II in Fig.

As can be seen from FIG. 1, the sports shoe according to the innovation has the shape of a boot. He persists essentially from a shaft 1, which, corresponding to the shape of the boot, extends well above the ankle height of the user extends upwards, as well as from a flexible outsole 2 (shell sole), which e.g. made of rubber. The shaft 1 has a slip-in opening 3 that extends far forwards into the leaf of the shaft and which is framed by an eyelet leather with eyelets 5. The eyelet leather 4 extends to the upper edge of the shaft. The hatch 3 is covered on the inside by a well-padded tongue 6.

As the cross section according to FIG. 2 shows, the shaft 1 is at least on its outer ankle facing side, but expediently also softly padded on the inside executed. For this purpose it consists of an outer cover layer 8 made of strong leather, one on top following relatively thick foam layer 9, made of a further thinner foam layer 1o with a foam that is denser than the foam layer 9 and an inner cover layer 11 made of smooth, fine synthetic leather. On the inside of the outer leather cover layer 8 are, as well can be seen from the cross section, two stiffening elements 12 fixed, for example glued.

These stiffening elements 12 have the shape of flat bars (see FIG. 1), which are approximated extend in the vertical direction from the upper edge of the outsole 2 to near the upper edge of the shaft. Included the front flat bar is slightly longer than the rear and both flat bars diverge slightly downward. Their distance from one another and their position are chosen so that the ankle of the user about to lie between the two. Both stiffening elements 12 are at their upper ends rounded. The cross-sectional shape of the flat bars 12 is shown in FIG. 2; the width is about 2 to 2.5 cm. Hard-set polyamide, which has a relatively high strength, is selected as the material and thus has flexural rigidity.

The stiffening effect achieved by the innovation is essentially based on the outside of the shoe on the flexural rigidity of the stiffening elements 12 and the fixation of the shaft on these stiffening elements 12 by gluing or the like. This is one of the stiffening elements 12 When twisting outwards, opposite resistance is transferred to the entire outside of the shaft, so that this behaves largely rigidly. This behavior is also supported by the Lacing that extends over the ankle, pulling the shaft through the ankle joint of the user tightly encloses. However, since the shoe is resiliently deformable, the user can use it perform the natural rolling process of the foot when walking and - depending on the progress of the healing process after a ligament operation - also the Increasing strain on the foot. Due to the external stiffening of the shaft 1, only those foot movements

blocks, which put strain on the ankle's outer ligaments, which have been injured by ankle twisting could lead.

The stiffening of the shaft 1 can be increased if one, preferably the rear, or both stiffening elements 12 with a heel cap stiffening get connected. In Fig. 1 is such a heel cap reinforcement, which is also from Consist of plastic and can be arranged between the individual layers of the shaft 1, indicated by dashed lines and denoted by 13. The stiffening element 12 can with this heel cap stiffening 13 be glued; In such a case, however, it is more appropriate to use both parts to be produced in one piece. This removes the user's heel bone and ankle from the surface of the foot starting from the sole, so that twisting is prevented.
