Abstract

PURPOSE: To prevent water from entering a midsole region by forming a midsole structure from two material layers coupled together, and forming a projection of a specific width used for sewing vamps to a lower layer. CONSTITUTION: An upper layer 1 is made of a typical midsole material, e.g. a natural or synthetic product, e.g. leather or synthetic leather. Also, the upper layer 1 is constructed of a number of layers such as foam layers having, e.g. a midsole made of leather and a lining leather cover. A lower layer 2 is made of a watertight material, e.g. a covered planar knit fabric, e.g. a fabric, fleece, knit products. The lower layer 2 has a projection which is 1 to 2 mm in width, used to sew vamps together, and is securely coupled to the upper layer 1 by an adhesive. The midsole structure can be coupled to the vamp materials by an economical method. Since the sewing or corrugated lamination is done outside an inside shoe region, water cannot enter inside the shoe.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an insole structure for shoes manufactured in California and a method for using the insole structure.
With a wavy insole (mit angestrobelter
Brandsohle) California shoes, as well as imitated moccasin shoes with sewn or corrugated insole structure, etc. using insole structure.

[0002]

BACKGROUND OF THE INVENTION Shoes as footwear support the foot during walking movements, avoid foot deformation, protect the foot from the external influences of moisture and cold air, and release heat and water from the foot. It fulfills many of the challenges of adjusting, that is, obtaining a comfortable environment.

A myriad of developments are known for improving the fulfillment of one or another and / or all the tasks. There have also been numerous attempts to protect the foot from the external influences of humidity, ie moisture or water, while at the same time taking into account the release of moisture, especially sweat, in the form of steam. In this case another product has been developed, for example a watertight but water vapor permeable membrane such as SYMPATEX.

One method for protecting the foot from water, for example as is done in the case of imitated moccasin-type shoes, provides the shoe with a water-tight, water vapor-permeable membrane of the type described above. Is provided with a sock structure.

In addition, if a structure of this kind produces an effect such that the foot is well protected from the direct influence of water in the form of liquid, the water is especially vulnerable to insoles. Entry into the inside of the shoe at locations that are typically important for protection is unavoidable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an insole structure which does not allow sufficient ingress of water in the insole region. It is a further object of the invention to provide an insole structure which does not have the seams used for the connection between the upper and the insole on the inside of the shoe. Another object of the present invention is to provide an insole structure that can be easily sewn onto an upper in an economical manner.

[0007]

SUMMARY OF THE INVENTION The problem is that the insole structure consists of at least two layers of material joined together, wherein the lower layer is a projection used for stitching uppers at least 1 mm wide. (Ueberstand) and is solved by a California insole insole structure.

The protrusions are preferably at least 2 mm
Is the width of. The lower layer may be, for example, a textile material, and the upper layer may be leather or synthetic leather. In a particularly advantageous embodiment of the invention, the lower layer consists of a watertight material. Further, the upper layer may have a multi-layered structure.

The insole structure according to the present invention comprises a California shoe having a sewn or corrugated veneer insole, a simulated moccasin shoe having a sewn insole structure and a wavy veneer. It is particularly suitable for manufacturing imitated moccasin shoes having a midsole structure. An insole structure according to the invention, a surface material and a lining present inside the surface material,
The shoe produced according to the invention has, according to the invention, a lining with a watertight film, the film being particularly preferably additionally water vapor-permeable.

The upper layer may consist of typical insole material, such as natural or synthetic products, such as leather, synthetic leather, such as Texon. The upper layer may be, for example, a leather insole (Lauffellauflage) or a lining leather covering (Fut
It may be composed of a number of layers such as a bubble layer having a terlederueberzug).

The lower layer is preferably a watertight material,
For example, it may be a coated textile fabric in the form of a plane, for example, a woven fabric, a fleece or a knit product. The lower layer is firmly bonded to the upper layer by an adhesive.

[0012]

EXAMPLE An insole can be provided in a conventional manner to the insole structure with the fixed shoe upper. The insole may be glued or otherwise injection molded. Further details can be confirmed by referring to FIG.

FIG. 2 illustrates a California shoe having an insole structure according to the present invention. Outsole (La
ufsohle) is described as a so-called shell bottom or tank bottom. The surface material consists of leather. Inside there is a backing with a water vapor permeable film (SYMPATEX-film). The lining and leather facing material are adhered to each other in the lower region by a watertight neoprene adhesive.

The insole structure according to the invention can be combined with the upper material without problems in an economical manner. Since the stitching or corrugation is performed outside the inner shoe area, water cannot penetrate the inside of the shoe through said positions. The insole does not have a seam on the inside of the shoe, which contributes to an improved aesthetic appearance as well as the advantage that no water can penetrate at this seam.

The easier processing of the insole structure is advantageous in the production of the mimicked moccasins.
