Apparatus and Method for Strobel high-heel shoes

Abstract

A shoe and a process for fabricating high-heeled shoes or pumps incorporates Strobel technology having an upper outer material with a lower end region of the outer material located in a lower upper end region, an upper lining material, which is arranged on the inner side of the upper outer material, incorporates a functional layer and has a lower end region of the lining material, the end region of the lining material having a lining edge that is not covered by the upper outer material, and a connecting band, resulting in a comfortable high-heeled shoe that can be worn all day and reduces foot stress over conventional high-heeled shoes.

1 . A shoe upper, having: an upper outer material with a lower end region of the outer material located in a lower upper end region, an upper lining material, which is arranged on the inner side of the upper outer material, incorporates a functional layer and has a lower end region of the lining material, the end region of the lining material having a lining edge that is not covered by the upper outer material, and a connecting band, which extends around the periphery of the upper end region and is joined on a first longitudinal side to the end region of the outer material but not to the end region of the lining material, and is joined on a second longitudinal side to the end region of the lining material but not to the end region of the outer material, band wherein at points of curvature of the lower periphery of the upper end region the connecting band extends in an arc corresponding to the local radius of curvature, with the two longitudinal sides of the connecting band having different degrees of curvature band, in such a way that, for an arc sector lying in the respective curvature, with a predetermined unitary sector angle, the arc lengths of the two longitudinal connecting band sides belonging to this arc sector differ from each other the more, the greater the curvature of the respective arc sector is, the arc length of the first longitudinal side of the connecting band being longer than the arc length of the second longitudinal side of the connecting band at points with convex curvature of the lower periphery of the upper end region, corresponding to the differing curvatures and arc lengths of the outer material end and the lining material end region. 
     
     
         2 . The shoe upper as claimed in  claim 1 , in which the arc length of the second longitudinal side of the connecting band is longer than the arc length of the first longitudinal side of the connecting band at points of the upper end region periphery with a concave curvature. 
     
     
         3 . The shoe upper as claimed in  claim 1 , in which the lining edge that is not covered by upper outer material is formed by an overhang of the end region of the lining material with respect to the end region of the outer material. 
     
     
         4 . The shoe upper as claimed in  claim 1 , with a substantially rigid connecting band, in which the differences in arc length of the two longitudinal sides of the connecting band, which are dependent on the respective arc curvature, are incorporated correspondingly into the band at the production stage. 
     
     
         5 . The shoe upper as claimed in  claim 4 , with a punched connecting band. 
     
     
         6 . The shoe upper as claimed in  claim 4 , with an injection-molded connecting band. 
     
     
         7 . The shoe upper as claimed in  claim 1 , with an elastic connecting band, which is joined on its first longitudinal side to the outer material end region while being subjected to longitudinal tensile pre-stress. 
     
     
         8 . The shoe upper as claimed in  claim 1 , with a deformable connecting band, which is joined on its first longitudinal side to the outer material end region while being subjected to longitudinal tensile pre-stress leading to plastic deformation. 
     
     
         9 . The shoe upper as claimed in  claim 1 , in which the connecting band is joined on its second longitudinal side to the lining material end region while being subjected to longitudinal tensile pre-stress. 
     
     
         10 . The shoe upper as claimed in  claim 1 , in which the first longitudinal side of
 the connecting band is sewn to the end region of the outer material.
