  • a) the thickening 5 is provided at least in the forefoot area where it supports the tread surface of the foot, it can also be present in the middle and / or rear foot area, in particular in the foot bone area of the middle and / or rear foot,
  • b) the lateral boundary 6 (thickening limitation) is offset with respect to the support sole limitation 3 soles so far inward that a gusset recess 7 is formed on the underside of the insole between the support sole limitation 3 and the thickening limitation 6 , into which, as shown in FIG. 3, the shoe upper 8 is inserted in the area of the gusset and insole there as well as in the outer area of the shell edge 4 on the edge of the shell, the thickening 5 normally having the same thickness as the shoe upper material 8 in the area of the gusset, so that the gusset 9 together with the thickening 5 form a practically flat underside to which an outsole 10 (see FIG. 3) can be glued over the entire surface; and
• 4. In addition, means for transverse stiffening and / or longitudinal flexibilization of the support sole 2 and / or the thickening 6 , at least in the forefoot area, if appropriate also in the middle and / or rear foot area, are provided.

The means for transverse stiffening and / or longitudinal flexibility of the support sole and / or the thickening are in FIGS . 2 and 3 a structure sole 11 , which consists for example of querpro filierte spring steel and extends in the area of the support sole 2 , this support sole 11 by flexible Materials 12 and 13 is embedded, so that the support sole 2 has a flat upper and lower surface, which can pass over the entire surface in the thickening 5 and laterally seamlessly in the lenrand 4 Scha.

As for the other preferred features of the structural sole reaches, in this regard, the explanations above referenced in the general part of the description.

Another essential means with which the thickening 5 can be made longitudinally flexible and cross-stable is shown in FIG. 1, according to which incisions 14 are provided in the thickening transversely to the longitudinal direction of the insole, through the entire thickness of the thickening 5 or only a part thereof Thickness can pass through and give the thickening a ladder-like structure, as FIG. 1 shows particularly clearly.

The angles α and γ already explained in more detail above, under which the transverse stiffening means, for example the lei-like projections 15 between the incisions 14 of the thickening 5 and / or the mountains 16 and valleys 17 of the corrugated structural sole 11 , preferably run, and the same meaning tend with the direction of the maximum transverse stiffening, as well as the angles β and d of the maximum longitudinal flexibility, which is normally perpendicular to the maximum transverse stiffening ver, are shown in FIG. 1 for clarity, the longitudinal axis of the sole being designated by 18 .

In addition, notches or wedge-shaped cuts 19 can be seen in FIG. 1, which are provided in the shell edge 4 in the region of the predetermined bend, in particular the bale, in order to provide a web effect (resistance to the predetermined bend) and / or a throwing up (bending out or forming folds) ) to prevent the bowl edge 4 .

Finally, in Fig. 3 shows the shoe to the foot width of the wearer insole 20 , which can be inserted positively into the top of the shell edge insole 1 , so that it verrutschungssi cher by the shell shape and by the stability of the shell edge insole according to the invention deformation-proof is held and guarantees a highly stable adjustment to the foot width.

In addition, further details and advantages of the shell rim insole according to the invention in its basic embodiment and in its various configurations are described and explained as follows:
It is a shell edge insole that supports the foot, which forms the basis for a multi-width system, which has a thickening 5 in the area of the ball mass, preferably with ladder-like transverse ribs that ensure lateral stability.

The shell edge insole comprises a base 2 , 5 and a side shell edge 4 . The lateral edge 4 of the shell preferably has a height h of 3.5-8 mm at the front in the forefoot area and 0 to 18 mm at the rear in the rear foot area for accommodating under different insoles 20 , with which different foot widths and foot thicknesses (multi-width system) are caught. The thickness of the thickening 5 is preferably between 1.0 to 3.0 mm, and the thickness s of the support sole 2 is preferably 1.0 to 5.0 mm.

The advantage of the shell rim insole is in particular that different foot widths and foot thicknesses can be accommodated with the same foot length by means of one shoe; the different volumes of the feet are absorbed by different insoles 20 .

The thickening 5 is preferably made of a compressed, thick material. In order to ensure lateral stability and surefootedness, but not to impede flexibility, the thickening 5 of the thickened shell edge of the insole is preferably provided in a ladder-like manner with the transverse incisions 14 between the conductors 15 . The direction of the transverse incisions is based on the line of the loading processes and is preferably 77 ° to the longitudinal axis in the forefoot area for adults and 103 ° in the rear foot area.

Depending on the size of the shoe and the age of the child, these angles of the ladder-like transverse grooves can vary. The sum of the transverse grooves always always results in 180 °. For toddlers, a transverse groove in the forefoot area of 90 ° and in the rear foot area of 90 ° makes sense, for sizes 30 to 32 an angle of 86 ° in the forefoot area and 94 ° in the rear foot area, for sizes 33 to 35 an angle of 81 ° in Forefoot and 99 ° in the rearfoot area, for shoe sizes from 36 the adults form 77 ° and 103 °.

The advantage of these different angles is that the sole of the respective level of development of the foot fits to the development of the child 's foot from square foot to to support (slim) adult foot.

The thickening 5 of the bottom part of the shell edge insole intercepts all main stress zones of the foot in all phases of the stress process. The thickening 5 of the Bo dens 2 , 5 of the cup edge insole 1 does not extend to the edge of the insole outline, but is so far inward from it that there is enough space 7 and material for a gusset blow and for gluing the shaft 8 .

In order to avoid a web effect, notches 14 can also be made on the upper side in the shell edge 4 of the shell edge insole, which notches increase the flexibility of the insole 1 .

The cup-shaped insole 1 has wearing properties and is therefore defined differently from normal insoles. It is the defining element of the shoe. The shell edge insole 1 supports and guides, the insole 20 located there dampens and guarantees a pleasant foot climate, in particular due to a water absorption capacity.

The shell rim insole has, with the exception of the soft one Shell edges prefer a high Shore hardness, in particular a high Shore A hardness or Shore D hardness, preferably one Shore A hardness from 80 to 100 or a Shore D hardness from 70 to 100. This is especially true for thickening, if this has a ladder-like structure. To ensure the flexibility of the Scha To ensure that the edge of the as mentioned above - notched like a ladder or in another Made longitudinally flexible, the shell edge is preferred in  Notched area of the nominal bending curves (bales) Bridge effect or to throw up the edge of the bowl chen.

The adhesive surface of the thickening of the shell edge insole (according to the ball size) should be as flat as possible to be flat.

The shell edge insole consists of a one-piece or multi-piece material, which has a bowl edge shape, de ren shell edge adapts to the outer foot shape. The bowls The bottom can hold an insole of different thickness to compensate for different widths and has one Shell background, that of the shell sole outline so far back stands that it is the main stress zones in the foot movement supports, thus supporting the foot and enough space on the side offers to pinch or stick a shaft and the Foot leads. The insole provides cushioning in the rear foot area and bedding in the forefoot area guaranteed.

The outline of the thickening of the ball mass is identical to the minimum requirements for the transverse bracing.

The shell edge insole is the ideal insole for one Shoe.

FIGS. 4 and 5 show another preferred exporting approximate shape of an insole 22 according to the invention in a Ge samtansicht (Fig. 4) perpendicular to the insole underside and in a perspective partial view, laterally obliquely onto the bottom of the insole.

This insole 22 is, apart from the special features explained below, otherwise designed as the insole 1 of FIGS. 1, 2, and 3, so that in this respect to the description of FIGS. 1 to 3 and those used in these figures Fig. 4 and 5 additional reference characters is referred to, but - as in Figs. 1, 2 and 3 - the preferably made of spring steel structure sole 11 may be omitted, especially if sufficient transverse stiffening and longitudinal flexibility of the Insole 1 or 22 by other means, such as the ladder-like structure of the thickening 5 formed by the cuts 14 and the projections 15 in conjunction with a relatively hard thickening material (e.g. Shore A hardness from 80 to 100 or Shore -D hardness of 70 to 100) is effected.

Referring to FIGS. 4 and 5, the lateral edge 5 is formed 6 of the gene rell scale thickening as a sealing edge 21, the bulge structure formed without interruptions to that of the projections 15 and the recesses 14 rotates and there structure by the Zwickelnschlagsausnehmung 7 against the thickening 14 , 15 seals, the thickness d of the sealing edge 21 preferably being equal to the thickness of the thickening structure 14 , 15 and the width of the sealing edge 21 preferably being less than the width of the projections 15 (which is, for example, between 5-15 mm), e.g. B. 0.5-2.5 mm to reduce the longitudinal flexibility as little as possible.

The sealing edge 21 prevents moisture or dampness, the z. B. due to a partially through or in some other way with holes, for. B. by nails, shears or the like. Provided outsole 10 (see FIG. 3) penetrates into the thickening structure 14 , 15 , in particular into the recesses 14 , via the gusset recess 7 can get into the interior of the shoe.

As the cross-sectional structures of FIGS. 2 and 3, which basically also apply to an insole 22 according to FIGS. 4 and 5, show, the support sole 2 together with the thickening 5 and preferably also with the shell edge 4 is designed as a sealing unit, which seals the upper side of the insole and thereby the inside of the shoe against moisture and wetness from below - even with holes in the outsole 10 . Such a seal against direct penetration of moisture or wetness is ensured by the dense insole layers also in the embodiment according to FIGS. 1, 2 and 3.

In addition, the embodiment according to FIGS. 4 and 5 prevents penetration of moisture and moisture through fine gaps, microchannels or the like in the bonded area between the upper leather plus any other layers associated therewith, such as, for. B. a textile membrane layer, and the gusset recess 7 .

Of course, the sealing edge 21 , which is preferably in one piece with the remaining thickening structure 14 , 15 and preferably also with the support sole 2 , may be unnecessary in a number of cases, such as, for. B. for shoes for interiors, such as slippers, indoor sneakers or the like. Or as in example with thickening structures in which the Querver stiffening and / or the longitudinal flexibility through a self-contained composite structure, such as. B. a graphite fiber reinforced plastic is achieved.
