DETAILED DESCRIPTION
[0041] FIG. 1 shows a foot 50 of a person with the longitudinal arch 51 that is to be specifically supported with the help of appropriate measures on shoe 1 or sandal 2. A view is reproduced from the inside of sandal 2, so that it can be seen that in the midsole 24 a pocket-like slot 7 is formed, in which inserts not shown here can be inserted. Through the slot 7 and the inserts not shown, the footbed 11 is specifically supported or developed in such a way that the longitudinal arch 51 can be optimally supported orthopedically. It can be seen that the sandal 2 has an outsole 4 and an insole 5, inserted between the midsole or midsoles 24. Another such midsole is designated with 10. This sandal 2 can be worn optimally fixed to the foot 50 with the help of the strap 6 and the closure 40 or the buckle 28. The inside is shown with 12, from which the insert not recognizable here can be inserted into the pocket-like slot 7.
[0042] FIG. 2.1 shows in a perspective view a shoe 1 formed as a sandal 2 with an upper insole 5 and a lower outsole 4. With such a sandal 2, the strap 6 spanning the foot 50 of the shoe wearer serves as a kind of upper shoe, whereby the strap 6 is also held below the insole 5. The strap 6 is fitted in two parts with a front belt section 25 and a rear belt section 26. Buckles 27, 28 serve as a connection, so to speak, for the production of the upper shoe. The slot 7, which is intended for the height adjustment inserts or the inserts 8, 9 between strap 6 and midsole 10, is recognizable on the inside 12 of the sandal 2. The midsoles 10, 24 are mainly made of cork. The inserts are designed on the top 41 in an arch form in order to optimally support the longitudinal vault 51.
[0043] The shoe 1 according to FIG. 2.1 is then also shown in FIG. 2.2 in the side view with optimal view of the outsole 4 and the belt 6 with the front belt section 25 and the rear belt section 26.
[0044] In the context of the production of footwear according to the invention, FIG. 3 shows the midsole 10 with adhesive strips 29, 30 for fastening the soles 4, 5, 10 to each other.
[0045] FIG. 4 shows a cushion 32 in the heel area. Slot 7 is clearly visible in the form of a circular segment 14 in the area below the longitudinal arch 51 of the human foot 50 with the two wedge-like inserts 8 and 9 with pins 16, 17, 18 or 16a, 17a, 18a on the inlay 8 and pins 16, 17, 18 on the part of the stabilization insert or the inlay 9. Holes 19, 20, 21 in the area of slot 7 correspond with the pins 16, 17, 18 or 16a, 17a, 18a, together as fasteners or locking means 15. The number 31 denotes a field furnished with glue.
[0046] FIG. 5 illustrates the belt 6 which is used to encompass the foot 50, with front belt 25 and rear belt 26 without installed buckles. The straps 25, 26 with several holes corresponding to the buckles are in the area of the rear straps 26, shown as an example with the reference number 36.
[0047] In FIG. 6, strap 6 is then connected to the cork midsole 10 via seam 37. Also indicated is the pocket-like slot 7, which has a seam 22 on its inside 23, which in a sense specifies the size of the pocket-like slot 7 and is also formed here in the form of a circle segment.
[0048] FIG. 7 shows the underside of the midsole 10, where adhesive strips 29, 30 are used to fix it towards the outsole 4. The straps are designated again with the reference numbers 6, 25, 26.
[0049] In the illustration according to FIG. 8, the connection is made between straps 6, 25, 26 on the one hand and the lower outsole 4 on the other hand. The reference numbers 8 and 9 in turn refer to the two wedge-like inserts.
[0050] FIG. 9 shows a look at an insole 5 with thongs 38 and 39.
[0051] Finally, FIG. 10 shows an insole 3 with the slot 7 in the area 13, which corresponds to the longitudinal arch 51 of the foot 50 of the shoe wearer. Here, arbitrarily designed stabilization inserts can be used in the form of small moldings and adapted to the needs of the wearer. Fasteners or locking means 15 are designated with the reference numbers 16-18 or 19-21.
[0052] FIG. 11 shows a pocket-like slot 7 in enlarged reproduction in which a wedge-like insert 8 is already inserted. The pocket-like slot 7 is slightly enlarged here to illustrate that the wedge-like insert 8 can be pushed down after insertion into the pocket-like slot 7, so that the locking means 15 in the form of pins 16, 17 can be inserted into the designated holes 19, 20 or the counterpart 45 to the locking means 15. After this has been done, the wedge-like insert 8, 9 can only be removed from the pocket-like slot 7 if it is deliberately lifted a little, whereby it is once again pointed out that here the pocket-like slot 7 is shown too large. The holes 19, 20 are made in the bottom 43 of the pocket-like slot 7 and have exactly the shape of the pins 16, 17. The pins 16, 17 are part of the bottom 42 of the wedge-like inlay 8, 9, whereby the top 41 is adapted to the roof 46 of the pocket-like slot 7 and is in contact there. It is not shown here that the wall 44 of the pocket-like slot 7 is smoothed or covered with an appropriate cloth to facilitate the insertion of the wedge-like inlay 8, 9.
[0053] FIG. 12 shows a top view of the pocket-like slot 7, whereby it becomes clear that the counterparts 45 or the pins 16, 17 fit exactly into the holes 19, 20, so that then the wedge-like insert 8 not shown here can no longer slip.
[0054] Certain variants are shown in FIGS. 13 and 14, whereby here the wedge-like inserts 8, 9 are provided with bars 49, 49′, which are mounted to match the notches 48, 48′ in the roof 46 or in the floor 43 in such a way that the wedge-like insert 8 can be smoothly guided into the insert back designated here with 47 in the pocket-like slot 7.
[0055] According to FIG. 15, it is provided an elevation 54 is formed at a distance to the insert back 47, so that a locking groove 58 is formed, in which a correspondingly formed round web 55 of the wedge-like inlay 8, 9 can snap into place, if the wedge-like insert 8, 9 has reached the insert back 47 in the pocket-like slot 7.
[0056] FIG. 16 finally shows an embodiment in which small magnets 56 are used, which are arranged in the insert back 47 in such a way that the metal wire 58 assigned to the leading edge 57 of the wedge-like inlay 8, 9 together with them ensures a fixing of the wedge-like inlay 8, 9 in slot 7.
[0057] In all the embodiments mentioned, the insert 8, 9 is fixed and immobilized in the pocket-like slot 7 by the locking agents 15 so that the determined optimal support of the foot 50 is always maintained. The wedge-like insert 8, 9 cannot slip—like the insoles—nor can it fall out of the pocket-like slot 7.
[0058] A footbed 11 does not necessarily have to be formed in the insole 5, because the wedge-like insert 8, 9 inserted into the pocket-like slot 7 provides the necessary “bulge”, i.e. a kind of footbed. As a rule, however, it is optimal if a standard footbed 11 is pronounced in the insole, so that at least one specification for the curvature to be caused by the insert 8, 9 is specified. The footbed 11 is virtually optimized with this wedge-like insert 8, 9.
[0059] All the features mentioned, including those to be taken from the drawings alone, are regarded alone and in combination as essential to the invention.
