Functional shoes

Abstract

Provided is a functional shoe comprising a shoe body, a flipper member extended in a plate shape from an end of the shoe body to be used as a flipper function and deformed upward to be folded so as to cover an upper surface of the shoe body, a fixing part fixing the flipper member, and a strap closely adhering the shoe body to a rear part of a user's foot, wherein the strap is selectively folded or unfolded to adjust a contact area with the user's foot. Accordingly, a shoe function and a flipper function are applied to one shoe to be conveniently used, a contact area with the user's foot may be increased to prevent the shoe from coming off when used in the water, and the strap may be folded to increase convenience outside the water.

         2 . The functional shoe of  claim 1 , wherein the strap comprises:
 a main strap configured to allow both ends thereof to be selectively and respectively fixed on side surfaces of the shoe body; and   a sub strap configured to be selectively folded to the main strap.   
     
     
         3 . The functional shoe of  claim 2 , wherein the sub strap comprises:
 an upper sub strap configured to selectively folded at an upper end of the main strap; and   a lower sub strap configured to be selectively folded at a lower end of the main strap.   
     
     
         4 . The functional shoe of  claim 3 , wherein the main strap comprises a plurality of strap pins to which a strap hole of the sub strap is fit and fixed. 
     
     
         5 . The functional shoe of  claim 4 , wherein the lower sub strap has a groove part formed in a central portion thereof, and
 wherein the upper sub strap is formed in a shape corresponding to the groove part when folded.   
     
     
         6 . The functional shoe of  claim 1 , wherein the fixing part comprises at least one fixing pin protruding from the upper surface of the shoe body, and
 wherein a fixing hole formed in the flipper member is fitted and coupled to the fixing pin.   
     
     
         7 . The functional shoe of  claim 6 , wherein the flipper member comprises:
 a flipper member body configured to be connected to an end of the shoe body in a plate shape; and   a deformation restraining part configured to be formed on a lower part of the flipper member body to allow the flipper member to be deformed and bent upward and inhibit the flipper member from being deformed downward.   
     
     
         8 . The functional shoe of  claim 7 , wherein the deformation restraining part comprises a plurality of cutout parts formed on a lower surface of the flipper member body. 
     
     
         9 . The functional shoe of  claim 2 , wherein the fixing part comprises at least one fixing pin protruding from the upper surface of the shoe body, and
 wherein a fixing hole formed in the flipper member is fitted and coupled to the fixing pin.   
     
     
         10 . The functional shoe of  claim 9 , wherein the flipper member comprises:
 a flipper member body configured to be connected to an end of the shoe body in a plate shape; and   a deformation restraining part configured to be formed on a lower part of the flipper member body to allow the flipper member to be deformed and bent upward and inhibit the flipper member from being deformed downward.   
     
     
         11 . The functional shoe of  claim 10 , wherein the deformation restraining part comprises a plurality of cutout parts formed on a lower surface of the flipper member body. 
     
     
         12 . The functional shoe of  claim 3 , wherein the fixing part comprises at least one fixing pin protruding from the upper surface of the shoe body, and
 wherein a fixing hole formed in the flipper member is fitted and coupled to the fixing pin.   
     
     
         13 . The functional shoe of  claim 12 , wherein the flipper member comprises:
 a flipper member body configured to be connected to an end of the shoe body in a plate shape; and   a deformation restraining part configured to be formed on a lower part of the flipper member body to allow the flipper member to be deformed and bent upward and inhibit the flipper member from being deformed downward.   
     
     
         14 . The functional shoe of  claim 13 , wherein the deformation restraining part comprises a plurality of cutout parts formed on a lower surface of the flipper member body. 
     
     
         15 . The functional shoe of  claim 4 , wherein the fixing part comprises at least one fixing pin protruding from the upper surface of the shoe body, and
 wherein a fixing hole formed in the flipper member is fitted and coupled to the fixing pin.   
     
     
         16 . The functional shoe of  claim 15 , wherein the flipper member comprises:
 a flipper member body configured to be connected to an end of the shoe body in a plate shape; and   a deformation restraining part configured to be formed on a lower part of the flipper member body to allow the flipper member to be deformed and bent upward and inhibit the flipper member from being deformed downward.   
     
     
         17 . The functional shoe of  claim 16 , wherein the deformation restraining part comprises a plurality of cutout parts formed on a lower surface of the flipper member body.
