Abstract
Description
- This invention relates to a shoe comprising an upper and an insole secured to the upper and having a first layer with an aperture fully surrounded by material of said layer, a second layer attached to the first layer, and an inlay of resilient material positioned in said aperture.
- A shoe of this kind, known from US-A-2 055 574, advantageously combines a resilient support of the foot with hardly any influence on the fit of said shoe and hence hardly any effect, if any effect at all, on the appearance of the shoe can be perceived.
- Using insoles of this known kind does, however, involve some mayor problems. The inlay of resilient material is enclosed by a cover layer and a layer of rubber material. The layer of rubber material forms a barrier blocking ventilation of the foot and absorption by layers beneath said layer of rubber material. Moreover, applying the layer of rubber material with the inlay positioned precisely on top in order to ensure an adequate fit of both said parts extending into the aperture of the first layer forms an elaborate manufacturing step.
- Other problems occur, when said insoles are to be used in shoes of a kind in which the upper is lasted and under tension secured to the insole. As said insole consists of only a thin linen sheet with a stepped configuration for entering the aperture in the first layer, it is not suitable for withstanding the tension forces during said processing. In so far as said layer and its attachment to the first layer withstand said forces, at least unacceptable side- long displacements occur by undoing the stepped configuration.
- It is an object of the invention to provide a shoe with a soft foot support under avoiding the above discussed problems in both manufacture and use and maintaining an optimum fit.
- In accordance with the invention, this is achieved in a shoe of the kind referred to in the opening paragraph in that said inlay is glued to said second layer on the same side as said first layer, the second layer extending in a generally straight line between opposing generally vertical side parts of the upper and secured to the upper by means of a welt along at least a considerable part of the outer edge region of the insole. Said second layer, which extends in a generally straight line and to which the first layer and the inlay are directly attached, forms the base of the insole capable of withstanding tension forces without deforming the fit of the shoe. As a result this shoe is particularly suited for manufacturing according to the Goodyear welt system, i.e. a processing in which the upper is lasted and, often with the addition of a leather strip, under tension stitched to a welt secured along at least a considerable part of the outer region of the insole. When said second layer is pulled into a generally flat configuration by the forces exerted thereon through the welt during the securing processing carried out under tension, the shape of the outer region of the insole turned to the lasted upper is, without the presence of the outsole, in accordance with the desired shape in the completed shoe. Along said outer edge region said first layer forms a reinforcement of the insole for reliably interconnecting the upper and the insole by means of the welt. Since according to the invention the inlay is directly attached to the second layer additionally enclosing with a layer of elastic material isn't necessary. Thus apart from a cost reduction and a better fit ventilation and absorption will not be hindered. Moreover, a reliable and durable attachment of a cover layer directly to the first layer is possible without any intermediate layers of rubber material, so stitching of the insole isn't required. Other advantages of the invention are further minimizing of the thickness of the insole with inlay and obtaining a tighter fit of the material surrounding the inlay and thus a more effective supporting edge against resilient lateral deflection.
- The thickness of the inlay should preferably be such that the foot supported on the soft footbed doesn't come into contact with the upper edges of the aperture in the first layer of the insole. In accordance with a further embodiment of the invention, therefore, as the shoe having an inlay with in an uncompressed condition a thickness larger than that of the first insole layer, the arrangement preferably being such, that in a compressed condition from footpressure said thickness is equal to, or virtually equal to, the thickness of said first insole layer, resulting in an optimum comfort and fit.
- A strong very durable construction of the insole can be obtained when, according to a further embodiment of the invention, said second layer is made of leather and preferably leather of the same kind as the leather of the first layer. Due to equal responses of both layers to changes in temperature and humidity as well as to forces exerted thereon a very reliable and durable attachment between said first and second layer is thus to be obtained. This homogeneous construction of the insole is advantageous too as relative humidity barriers in the insole are avoided.
- The shoe according to the invention will now be discussed and elucidated in more detail with reference to an exemplary embodiment illustrated in the accompanying drawings. In said drawings,
- Fig. 1 shows the shoe in longitudinal section;
- Fig. 2 shows, on an enlarged scale, the toe portion of the shoe illustrated in Fig. 1; and
- Fig. 3 shows the insole with inlay in top plan view.
- The shoe comprises an upper 1, which as shown in Fig. 2, is connected by means of stitching 2 to a
welt 3 and aleather strip 4.Welt 3 is secured to an insolelower layer 5 which, in turn, is glued to an insoleupper layer 6. As best shown in Fig. 3, an aperture is formed in the latter, in which aninlay 7 is accommodated which, in turn, is glued to the insolelower layer 5. Aliner sole 8 is glued to inlay 7 and inner soleupper layer 6 by way of shoe liner. Secured to theleather strip 4, by means of stitching 9, is theoutsole 10, with the space remaining between the insolelower layer 6 and theoutsole 10 being filled with a layer ofcork 11. - Embedded in
cork layer 11, in the middle portion of the shoe, is an arch-support 12. Finally, at the heel portion of the shoe, aheel 13 is secured to outsole 10. - For the manufacture of such a shoe, the upper 1 is produced by cutting pieces of leather to size and sewing these together. The insole
lower layer 5, the insoleupper layer 6, the latter with an aperture therein, andinlay 7 are also cut to size and glued together, whereafter thewelt 3 is secured to the bottom of the insolelower layer 5. Fromwelt 3, the non-secured portion initially extends at an angle to the insolelower layer 5, as a result of which this portion can be connected to upper 1 andleather strip 4, by stitching 2, after lasting. After this operation,welt 3 is moved into the position shown in Fig. 2, whereafter arch-support 12 andcork layer 11 are applied. Theoutsole 10 is then to be secured tostrip 4 by means of stitching 9, and finallyheel 13 is secured tooutsole 10. - Naturally, many modifications and variants are possible without departing from the scope of the invention. Thus the above manufacturing process for the shoe can be supplemented with some further operations. Furthermore, the aperture in the insole
upper layer 6 as shown in Fig. 3 can be extended to cover virtually the entire foot support, for example in such a manner that the insole upper layer only consists of a margin surronding a correspondingly enlargedinlay 7. Also, still further ornamental strips can be secured towelt 3 and, hence to the insole, along with upper 1 andleather strip 4 by means of the stitching.
