Shoe structure

Abstract

A shoe structure includes a shoe body and a wearing element installed onto the shoe body. The shoe body includes a first folding slot, a second folding slot, a third folding slot and a fourth folding slot. The first and second folding slots are extended from the center of a first side towards a second side of the shoe body with an included angle defined between the first and second folding slots. The third and fourth folding slots are extended from the second side towards the first side, and the third and first folding slots form a first folding line, and the fourth and second folding slots form a second folding line. The first and second folding lines divide the shoe body into a front stepping portion, a middle portion and a heel portion which can be folded along the first and second folding lines for a convenient storage.

What is claimed is: 
     
         1 . A shoe structure, comprising:
 a shoe body, with a first side and a second side, further comprising:
 a first folding slot, formed at a top surface of the shoe body, and extended from the center of the first side towards the second side; 
 a second folding slot, formed at the top surface of the shoe body, and extended from the center of the first side towards the second side, and an included angle being defined between the first folding slot and the second folding slot; 
 a third folding slot, formed at the top surface of the shoe body, and extended from the second side towards the first side, and the third folding slot and the first folding slot forming a first folding line; and 
 a fourth folding slot, formed at the top surface of the shoe body, and extended from the second side towards the first side, and the fourth folding slot and the second folding slot forming a second folding line; and 
   a wearing element, installed at the top surface of the shoe body;   wherein the first folding line and the second folding line divide the shoe body sequentially from the front to the rear into a front stepping portion, a middle portion and a heel portion, and the front stepping portion and the middle portion are folded along the first folding line, and the middle portion and the heel portion are folded along the second folding line.   
     
     
         2 . The shoe structure of  claim 1 , wherein the shoe body further comprises:
 a fifth folding slot, formed at a bottom surface of the shoe body, and disposed at a position corresponding to the first folding slot;   a sixth folding slot, formed at the bottom surface of the shoe body, and disposed at a position corresponding to the second folding slot;   a seventh folding slot, formed at the bottom surface of the shoe body, and disposed at a position corresponding to the third folding slot; and   an eighth folding slot, formed at the bottom surface of the shoe body, and disposed at a position corresponding to the fourth folding slot.   
     
     
         3 . The shoe structure of  claim 1 , wherein the included angle falls within a range from 65° to 75°. 
     
     
         4 . The shoe structure of  claim 3 , wherein the included angle is equal to 70°. 
     
     
         5 . The shoe structure of  claim 1 , wherein the first folding slot or the third folding slot has a length falling within a range from 20% to 35% of the length of the first folding line. 
     
     
         6 . The shoe structure of  claim 1 , wherein the second folding slot or the fourth folding slot has a length falling within a range from 20% to 35% of the length of the second folding line. 
     
     
         7 . The shoe structure of  claim 1 , wherein the first folding line and the second folding line have equal lengths. 
     
     
         8 . The shoe structure of  claim 1 , wherein the front stepping portion has a thickness falling within a range from 5 mm to 10 mm. 
     
     
         9 . The shoe structure of  claim 8 , wherein the front stepping portion has a thickness of 7 mm. 
     
     
         10 . The shoe structure of  claim 1 , wherein the heel portion has a thickness falling within a range from 8 mm to 13 mm. 
     
     
         11 . The shoe structure of  claim 10  wherein the heel portion has a thickness of 11 mm. 
     
     
         12 . The shoe structure of  claim 1 , wherein the first folding slot, the second folding slot, the third folding slot or the fourth folding slot has a depth falling within a range from 2 mm to 5 mm. 
     
     
         13 . The shoe structure of  claim 12  wherein the first folding slot, the second folding slot, the third folding slot or the fourth folding slot has a depth of 2 mm.
