"Shoe with form-retaining support structure"

The invention relates to a shoe in which a shape-retaining ! Shoring is incorporated, which is made of a plastic molded part produced by injection molding with a »wipe of the heel and ball of the foot extending rigid insole part and one with this manufactured in one piece, up to about The shoe joint area consists of a pre-cut heel cap. The outside of the support structure is marked with the =., Covered upper of the shoe.

With such a shoe, this simply forms e.g. by spraying or pouring, load-bearing structures that can be manufactured not only the shape-retaining arch of the shoe, but it also serves as a shape-retaining support for the upper

Lower quality leathers can be used without the processing of an intermediate lining being necessary. Since the supporting frame invites itself to be produced as an injection-molded part, this is also the prerequisite for a strip-appropriate Given training, so that a shoe equipped with such a support frame is a lot has a more precise fit than in cases in which the upper material of the shoe, e.g. the upper leather, forms the shaping element.

The invention is based on the observation that Difficulties can arise with regard to the formation of the supporting structure in line with the strips if the Insole part of the supporting framework has a much greater thickness than the heel cap. Due to the different speed at which the shoring solidifies in the individual areas, can arise warping the framework through uneven shrinkage.

according to the invention

These difficulties can essentially be overcome by this remove that the supporting structure extends over the entire length of the shoe, under the conditions of injection molding does not shrink or shrink only slightly-

Pearly pressed fiber cores can also be used easily glued to the inner lining of the shaft

In a preferred embodiment of the invention in the area of the heel cap in the hittelsone of the goose sole a preferably elongated recess is provided, which is filled by the plastic of the supporting structure, which is coated on the underside of the goose sole. this further counteracts any warping of the uterus when the spritslingo cools down.
