Layered shoe upper

Abstract

A shoe includes an upper and a sole. The upper includes an outer layer having a first knitwear and an inner layer having a second knitwear. The first knitwear differs from the second knitwear with regard to at least one of a yarn used, a stitch structure, an alignment, and a form.

That which is claimed is: 
     
         1 . An upper for a shoe comprising:
 (a) an outer layer comprising a first knitwear; and   (b) an inner layer comprising a second knitwear;   (c) wherein the first knitwear differs from the second knitwear with regard to at least one of a yarn used, a stitch structure, an alignment, and a form.   
     
     
         2 . The upper according to  claim 1 , wherein the inner layer is substantially formed by the second knitwear. 
     
     
         3 . The upper according to  claim 1 , wherein at least one of the first knitwear and the second knitwear is weft-knitted. 
     
     
         4 . The upper according to  claim 1 , wherein at least one of the first knitwear and the second knitwear is warp-knitted. 
     
     
         5 . The upper according to  claim 1 , wherein the second knitwear comprises a thinner yarn than the first knitwear. 
     
     
         6 . The upper according to  claim 1 , wherein the first knitwear comprises a more coarsely knitted stitch structure than the second knitwear. 
     
     
         7 . The upper according to  claim 1 , wherein the second knitwear comprises greater humidity absorbing properties than the first knitwear. 
     
     
         8 . The upper according to  claim 1 , wherein the second knitwear comprises greater humidity wicking properties than the first knitwear. 
     
     
         9 . The upper according to  claim 1 , wherein the second knitwear comprises a tongue area. 
     
     
         10 . The upper according to  claim 1 , wherein the first knitwear comprises at least one opening through which the second knitwear is visible. 
     
     
         11 . The upper according to  claim 1 , wherein the second knitwear is more stretchable than the first knitwear. 
     
     
         12 . The upper according to  claim 1 , wherein the first knitwear and the second knitwear are aligned relative to each other so that the upper comprises substantially isotropic stretchability. 
     
     
         13 . The upper according to  claim 1 , wherein the first knitwear and the second knitwear are aligned relative to each other so that a direction of greatest stretchability of the first knitwear is substantially perpendicular to a direction of greatest stretchability of the second knitwear. 
     
     
         14 . The upper according to  claim 1 , wherein the second knitwear is aligned so that a direction of greatest stretchability of the second knitwear is substantially perpendicular to a longitudinal axis of the upper. 
     
     
         15 . The upper according to  claim 1 , wherein the first knitwear is aligned so that a direction of greatest stretchability of the first knitwear is substantially parallel to a longitudinal axis of the upper. 
     
     
         16 . The upper according to  claim 1 , wherein the first knitwear and the second knitwear are aligned relative to each other so that courses of the first knitwear are substantially perpendicular to courses of the second knitwear. 
     
     
         17 . The upper according to  claim 1 , wherein the inner layer is detachably connected to the outer layer. 
     
     
         18 . The upper according to  claim 17 , wherein the inner layer is detachably connected to the outer layer by a hook and loop fastener, a button, or lacing, in a form-fit or force-fit manner. 
     
     
         19 . The upper according to  claim 1 , wherein the inner layer is non-detachably connected to the outer layer. 
     
     
         20 . A shoe comprising:
 (a) an upper comprising:
 (i) an outer layer comprising a first knitwear; 
 (ii) an inner layer comprising a second knitwear; and 
 (iii) wherein the first knitwear differs from the second knitwear with regard to at least one of a yarn used, a stitch structure, an alignment, and a form; and 
   (b) a sole.   
     
     
         21 . A method of manufacturing an upper comprising:
 providing an outer layer comprising a first knitwear; and   providing an inner layer comprising a second knitwear;   wherein the first knitwear differs from the second knitwear with regard to at least one of a yarn used, a stitch structure, an alignment, and a form.
