  • FIG. 1 shows a side view of a water shoe according to the present invention.
  • the water shoe comprises a shoe body 1 and a first pair of wings 3.
  • the wings 3 are symmetrical, they are glued together, and are linked to the shoe body 1, below the shoe. In this way, the wings constitute part of a sole 2 (not visible in the figure) of the shoe 1.
  • a float 4 is integrated below the wings 3, at the level of the sole 2, so that a of its faces covers the sole 2.
  • the float 4 in the shape of a tetrahedron with triangular faces is integrated over approximately the entire surface of the sole 2.
  • the wide side of the triangle is located on the heel side of the shoe 1, in this way the pointed end of the triangle is located on the front of the shoe in order to give an aerodynamic appearance to the float 4, to be able to move forward more easily in the water.
  • the wings 3 are fixed by pivot connections. Said connections allow the wings 3 the flexibility of movement in the water.
