Lightweight shoes

Abstract

According to an embodiment of the present disclosure, a lightweight shoe comprises an outsole and a vamp attached or sewn to the outsole to cover a foot, wherein the vamp includes a foam member and a fiber layer to surround the foam member.

What is claimed is: 
     
         1 . A lightweight shoe, comprising:
 an outsole; and   a vamp attached or sewn to the outsole to cover a foot, wherein the vamp includes a foam member and a fiber layer to surround the foam member.   
     
     
         2 . The lightweight shoe of  claim 1 , wherein the foam member includes at least one of Styrofoam™, expanded polyethylene (EPE), expanded polypropylene (EPP), or expanded in polystyrene (EPS). 
     
     
         3 . The lightweight shoe of  claim 1 , wherein the fiber layer includes at least one of chemical fiber, glass fiber, carbon fiber, aramid fiber, or ultrahigh molecular weight resin fiber. 
     
     
         4 . A lightweight shoe, comprising:
 an outsole;   a midsole formed on the outsole; and   a vamp attached or sewn to the midsole to cover a foot, wherein the midsole includes a foam member and a fiber layer to surround the foam member.   
     
     
         5 . The lightweight shoe of  claim 4 , wherein the foam member includes at least one of Styrofoam™, expanded polyethylene (EPE), expanded polypropylene (EPP), or expanded polystyrene (EPS). 
     
     
         6 . The lightweight shoe of  claim 4 , wherein the fiber layer includes at least one of chemical fiber, glass fiber, carbon fiber, aramid fiber, or ultra-high molecular weight resin fiber. 
     
     
         7 . The lightweight shoe of  claim 4 , wherein the midsole includes an open-top protection layer with a U-shaped cross section and a foam member filling the protection layer or the midsole includes a protection layer with an opened top and bottom and a foam member fitted in the protection layer. 
     
     
         8 . The lightweight shoe of  claim 7 , wherein the protection layer includes at least one of polyurethane or ethylene vinyl acetate. 
     
     
         9 . The lightweight shoe of  claim 7 , wherein the protection layer is a fiber layer including at least one of chemical fiber, glass fiber, carbon fiber, aramid fiber, or ultra-high molecular weight resin fiber. 
     
     
         10 . The lightweight shoe of  claim 7 , wherein the foam member includes at least one of Styrofoam™, expanded polyethylene (EPE), expanded polypropylene (EPP), or expanded polystyrene (EPS). 
     
     
         11 . A lightweight shoe, comprising:
 an outsole; and   a vamp attached or sewn to the outsole to cover a foot, wherein the outsole includes an open-top protection layer laving a substantially U-shaped cross section and a foam member filling the protection layer.   
     
     
         12 . The lightweight shoe of  claim 11 , wherein the protection layer includes at least one of polyurethane, ethylene vinyl acetate, or rubber. 
     
     
         13 . The lightweight shoe of  claim 11 , wherein the protection layer is a fiber layer including at least one of chemical fiber, glass fiber, carbon fiber, aramid fiber, or ultra-high molecular weight resin fiber. 
     
     
         14 . The lightweight shoe of  claim 11 , wherein the foam member includes at least one of Styrofoam™, expanded polyethylene (EPE), expanded polypropylene (EPP), or expanded polystyrene (EPS). 
     
     
         15 . A lightweight shoe, comprising:
 an outsole:   a vamp attached or sewn to the outsole to cover a foot; and   an insole provided between the outsole and the vamp, wherein the insole includes a foam member and a fiber layer formed on the foam member.   
     
     
         16 . The lightweight shoe of  claim 15 , wherein the fiber layer includes at least one of chemical fiber, glass fiber, carbon fiber, aramid fiber, or ultra-high molecular weight resin fiber. 
     
     
         17 . The lightweight shoe of  claim 15 , wherein the foam member includes at least one of Styrofoam™, expanded polyethylene (EPE), expanded polypropylene (EPP), or expanded polystyrene (EPS).
