FUNCTIONAL SHOES

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.
