Upper and shoe

Abstract

An upper is formed using a fiber sheet that includes: a connected part in which a surface layer and an inner layer are connected to each other; and a non-connected part in which these layers are not connected to each other, in order to provide a shoe having a low risk of causing complicated production processes or discharge of a large amount of waste materials even when shoes with a large number of different types are produced.

1 . An upper of a shoe, the upper comprising:
 a fiber sheet comprising:   a surface layer configuring an outer surface of the shoe;   an inner layer disposed on an inner side of the surface layer; and   an intermediate layer between portions of the surface layer and the inner layer, such that the fiber sheet has   a connected part in which the surface layer and the inner layer are connected to each other by the intermediate layer; and   a non-connected part in which the surface layer and the inner layer are not connected to each other with the intermediate layer being absent therebetween, and each of the surface layer, the inner layer, and the intermediate layer comprises fibers.   
     
     
         2 . The upper according to  claim 1 , wherein the shoe comprises: a forefoot portion; a midfoot portion; and a rearfoot portion arranged in order from a front toward a back of the shoe, and
 an area ratio of the connected part to the non-connected part in the rearfoot portion is higher than that in the forefoot portion.   
     
     
         3 . The upper according to  claim 1 , wherein the shoe comprises: a forefoot portion; a midfoot portion; and a rearfoot portion arranged in order from a front toward a back of the shoe, and
 in the midfoot portion, an area of the connected part having a larger dimension in a vertical direction of the shoe than a dimension in a front-back direction of the shoe is larger than an area of the non-connected part having a larger dimension in the front-back direction than a dimension in the vertical direction.   
     
     
         4 . The upper according to  claim 1 , wherein the shoe comprises: a forefoot portion; a midfoot portion; and a rearfoot portion arranged in order from a front toward a back of the shoe, and
 an area ratio of the non-connected part to the connected part in the forefoot portion is higher than that in each of the midfoot portion and the rearfoot portion.   
     
     
         5 . The upper according to  claim 1 , wherein
 the fiber sheet comprises a warp knitted fabric, and   the surface layer comprises a front yarn, the inner layer comprises a lining yarn, and the intermediate layer comprises an intermediate yarn that is knitted on both the front yarn and the lining yarn.   
     
     
         6 . The upper according to  claim 1 , wherein at least a part of the surface layer comprises a monofilament yarn. 
     
     
         7 . The upper according to  claim 1 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
 a different member from the fiber sheet is housed in the space.   
     
     
         8 . A shoe comprising the upper according to  claim 1 . 
     
     
         9 . The upper according to  claim 2 , wherein
 the fiber sheet comprises a warp knitted fabric, and   the surface layer comprises a front yarn, the inner layer comprises a lining yarn, and the intermediate layer comprises an intermediate yarn that is knitted on both the front yarn and the lining yarn.   
     
     
         10 . The upper according to  claim 3 , wherein
 the fiber sheet comprises a warp knitted fabric, and   the surface layer comprises a front yarn, the inner layer comprises a lining yarn, and the intermediate layer comprises an intermediate yarn that is knitted on both the front yarn and the lining yarn.   
     
     
         11 . The upper according to  claim 4 , wherein the fiber sheet comprises a warp knitted fabric, and the surface layer comprises a front yarn, the inner layer comprises a lining yarn, and the intermediate layer comprises an intermediate yarn that is knitted on both the front yarn and the lining yarn. 
     
     
         12 . The upper according to  claim 2 , wherein at least a part of the surface layer comprises a monofilament yarn. 
     
     
         13 . The upper according to  claim 3 , wherein at least a part of the surface layer comprises a monofilament yarn. 
     
     
         14 . The upper according to  claim 4 , wherein at least a part of the surface layer comprises a monofilament yarn. 
     
     
         15 . The upper according to  claim 5 , wherein at least a part of the surface layer comprises a monofilament yarn. 
     
     
         16 . The upper according to  claim 2 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
 a different member from the fiber sheet is housed in the space.   
     
     
         17 . The upper according to  claim 3 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
 a different member from the fiber sheet is housed in the space.   
     
     
         18 . The upper according to  claim 4 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
 a different member from the fiber sheet is housed in the space.   
     
     
         19 . The upper according to  claim 5 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
 a different member from the fiber sheet is housed in the space.   
     
     
         20 . The upper according to  claim 6 , wherein the non-connected part has a space disposed between the surface layer and the inner layer, and
