Abstract

A soccer shoe improving the spin of a ball is provided. The soccer shoe comprises a sole and a shoe upper, and includes thereon a plurality of protrusions formed on an inner side area of a toe portion and an outer side area of the toe portion, each protrusion embedding therein an elastic wedge-shaped object, to thereby increase a spinning power of a soccer ball.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A soccer shoe comprising a sole and a shoe upper, characterized in that a plurality of protrusions are formed on both an inner side area and an outer side area of a toe portion, each protrusion embedding therein an elastic wedge-shaped object, to thereby increase a spin power of a soccer ball.  
     
     
         2 . The soccer shoe of  claim 1 , characterized in that each of said plurality of the protrusions is tilted toward front of the soccer shoe, and the height of the protrusions are gradually increasing from a protrusion at a toe side to a protrusion at a rear side of the soccer shoe.  
     
     
         3 . The soccer shoe of  claim 1  or  claim 2 , characterized in that the number of the protrusions is 6 for the inner side area of the toe portion and 5 for the outer side area of the toe portion.  
     
     
         4 . A soccer shoe comprising a sole and a shoe upper, characterized in that a plurality of protrusions are formed on both an inner side area and an outer side area of a toe portion to thereby increase a spin power of a soccer ball.  
     
     
         5 . The soccer shoe of  claim 4 , characterized in that each protrusion embedding therein an elastic wedge-shaped object to thereby enhance elasticity of said each protrusion.  
     
     
         6 . The soccer shoe of  claim 4 , characterized in that the direction of said each protrusion is normal to the surface of the shoe upper on which said each protrusion is formed.  
     
     
         7 . The soccer shoe of  claim 4 , characterized in that the direction of said each protrusion is tilted toward the toe side of the soccer shoe.  
     
     
         8 . The soccer shoe of  claim 4 , characterized in that the direction of said each protrusion is tilted toward the rear side of the soccer shoe.  
     
     
         9 . The soccer shoe of  claim 7  or  claim 8 , characterized in that the degree of tilt is 20 to 50 degrees.  
     
     
         10 . The soccer shoe of  claim 4 , characterized in that the space between said each protrusion is 0.5 to 4.0 cm.  
     
     
         11 . The soccer shoe of  claim 4 , characterized in that the height of said each protrusion is gradually varied depending on the location of said each protrusion so that a protrusion located nearest the toe side is the lowest and a protrusion located farthermost to the toe side is highest.  
     
     
         12 . The soccer shoe of  claim 11 , characterized in that a height difference between neighboring protrusions is 0.5 to 3.0 mm.  
     
     
         13 . The soccer shoe of  claim 5 , characterized in that a plurality of the wedge-shaped objects constitute a one-body object so that a bottom of each wedge-shaped object is attached to one plane object.  
     
     
         14 . The soccer shoe of  claim 13 , characterized in that a cross sectional view of each ridge of the one-body object is in triangular shape.  
     
     
         15 . The soccer shoe of  claim 13 , characterized in that a cross sectional view of each ridge of the one-body object is round.  
     
     
         16 . The soccer shoe of  claim 4 , characterized in that the numbers of the protrusions for the inner side area of the toe portion and for the outer side area of the toe portion are identical.  
     
     
         17 . The soccer shoe of  claim 4 , characterized in that the number of the protrusions is 6 for the inner side area of the toe portion and 5 for the outer side area of the toe portion.  
     
     
         18 . The soccer shoe of  claim 4 , characterized in that the shape of each protrusion is rectangular or square and a plurality of protrusions are formed about on the inner side area of the toe portion and the outer side area of the toe portion.  
     
     
         19 . The soccer shoe of  claim 4 , characterized in that the height of said each protrusion is identical to each other.  
     
     
         20 . The soccer shoe of  claim 4 , characterized in that said each protrusion is an elastic wedge-shaped object.
