Moisture-permeable waterproof shoe

Abstract

A moisture-permeable waterproof shoe includes a shoe-shaped inner sleeve defining a foot space and having an inclined annular top edge inclining downwardly from a front side to a rear side thereof, and an outer sock body including a main sock body portion that is sleeved on the shoe-shaped inner sleeve, an insertion portion higher than the inclined annular top edge, and an annular sewing portion extending from the insertion portion to the foot space and fixed to the shoe-shaped inner sleeve. The insertion portion defines an insertion opening communicating with the foot space, and has opposite front and rear ears, and two side portions connected between the front and rear ears.

What is claimed is: 
     
         1 . A moisture-permeable waterproof shoe comprising:
 a shoe-shaped inner sleeve that includes a moisture-permeable waterproof layer located on an outer side thereof, that defines a foot space having an open top end and a closed bottom end, and that has an inclined annular top edge inclining downwardly from a front side to a rear side of said shoe-shaped inner sleeve, said foot space having a foot space opening surrounded by said inclined annular top edge;   an outer sock body including a main sock body portion that corresponds to said shoe-shaped inner sleeve, that is sleeved on said shoe-shaped inner sleeve and that has an annular top edge, an insertion portion extending upwardly from said annular top edge of said main sock body portion, and an annular sewing portion extending downwardly from said insertion portion to said foot space and fixed to an inner surface of said shoe-shaped inner sleeve, said annular sewing portion having a bottom edge lower than said inclined annular top edge;   a connecting layer fixed between said shoe-shaped inner sleeve and said outer sock body; and   a sole fixed to a bottom surface of said main sock body portion;   wherein said insertion portion is higher than said inclined annular top edge, defines an insertion opening communicating with said foot space, and has a front ear, a rear ear opposite to said front ear, and two side portions connected between said front ear and said rear ear;   wherein said front ear has a front ear body portion, and two front wing portions extending rearwardly and respectively from left and right sides of said front ear body portion, each of said front wing portions having a top edge that inclines rearwardly and downwardly from a top edge of said front ear body portion;   wherein said rear ear has a rear ear body portion corresponding to said front ear body portion, and two rear wing portions extending forwardly and respectively from left and right sides of said rear ear body portion and corresponding to said two front wing portions, each of said rear wing portions having a top edge that inclines forwardly and downwardly from a top edge of said rear ear body portion;   wherein said top edge of said front ear body portion is higher than said top edge of said rear ear body portion; and   wherein said two side portions are connected between said two front wing portions and said two rear wing portions.   
     
     
         2 . The moisture-permeable waterproof shoe as claimed in  claim 1 , wherein said outer sock body has an extension portion that extends upwardly from said annular top edge of said main sock body portion and that is folded back inwardly to form said insertion portion and said annular sewing portion. 
     
     
         3 . The moisture-permeable waterproof shoe as claimed in  claim 1 , wherein said shoe-shaped inner sleeve further includes a lining layer serving as said inner surface thereof, an outer fabric layer, and a foam layer fixed between said lining layer and said outer fabric layer, said moisture-permeable waterproof layer being fixed to an outer surface of said outer fabric layer, said annular sewing portion being sewn to said lining layer. 
     
     
         4 . The moisture-permeable waterproof shoe as claimed in  claim 1 , further comprising a tightening unit that includes a first tightening plate connected to said sole, a second tightening plate connected to said sole, and at least one tightening strap connected between said first tightening plate and said second tightening plate. 
     
     
         5 . The moisture-permeable waterproof shoe as claimed in  claim 4 , wherein:
 said first tightening plate includes a first plate body abutting against said main sock body portion, a first strap body extending rearwardly from said first plate body, and a first connecting member disposed on said first strap body;   said second tightening plate includes a second plate body abutting against said main sock body portion, a second strap body extending rearwardly from said second plate body, and a second connecting member disposed on said second strap body;   said first plate body and said second plate body are respectively disposed on left and right sides of said main sock body portion; and   said second strap body is longer than said first strap body, and extends around a rear side of said rear ear to releasably connect said second connecting member to said first connecting member.   
     
     
         6 . The moisture-permeable waterproof shoe as claimed in  claim 5 , wherein said first connecting member and said second connecting member are hook and loop fasteners. 
     
     
         7 . The moisture-permeable waterproof shoe as claimed in  claim 5 , wherein:
 said first plate body includes a first bottom end portion connected to said sole, and a first top end portion connected to said tightening strap; and   said second plate body includes a second bottom end portion connected to said sole, and a second top end portion connected to said tightening strap.   
     
     
         8 . The moisture-permeable waterproof shoe as claimed in  claim 7 , wherein said first top end portion includes a plurality of spaced-apart first through holes, said second top end portion includes a plurality of spaced-apart second through holes, and said tightening strap is a shoelace that is removably threaded through said first through holes and said second through holes. 
     
     
         9 . The moisture-permeable waterproof shoe as claimed in  claim 1 , wherein said outer sock body is a knitted sock. 
     
     
         10 . The moisture-permeable waterproof shoe as claimed in  claim 1 , wherein:
 said front ear and said rear ear are movable between a non-pulling state and a pulling state;   when said front ear and said rear ear are in said non-pulling state, said insertion opening has a width (W 2 ) smaller than a width (W 1 ) of said foot space opening; and   when said front ear and said rear ear are in said pulling state, said front ear and said rear ear are pulled apart from each other, and said width (W 2 ) of said insertion opening is larger than said width (W 1 ) of said foot space opening.
