  • one or more bands coupled to a side of the body in a direction perpendicular to a longitudinal direction of the body; and a pair of first fastening devices each coupled to both ends of the band to be fastened with each other.
  • the flippers worn with shoes may further include a shoe portion seated on the instep seating portion and coupled thereto, in which second fastening devices disposed on both side surfaces of the shoe portion and configured to be fastened with the pair of first fastening device may be coupled.
  • a plurality of protrusions may be provided to form a groove on a front surface of the body of the fin portion in the longitudinal direction.
  • the shoe portion may be any one of aqua shoes or sandals.
  • the entire outline of the fin portion may be formed in a trapezoidal shape having a short upper side, and the instep seating portion may be formed in a corresponding shape so that the shoe portion is inserted into the instep seating portion.
  • the fin portion may include a fold line perpendicular to the longitudinal direction of the body.
  • the pair of first fastening devices may be coupled to the pair of second fastening devices.
  • the present invention is to solve the above problems. That is, according to the present invention, the fin portion is detachably fastened to a shoe, and thus there is no hassle of wearing and taking off before and after entering water. In addition, there is no inconvenience of walking and acting by wearing the flippers for a purpose of protecting a foot or working before entering water. Moreover, there is an effect of serving a double purpose such as acceleration of underwater work and underwater movement, and underwater action, as well as protection of feet after entering water.
  • the flipper is easy to walk in a valley or on a seashore, the flipper has an area that can receive sufficient resistance to water from the fin portion in the water, and thus, it is possible to obtain a propulsion force.
  • the flipper can be used according to the function by changing the shape into a shoe shape or flippers shape with a simple operation as needed when working underwater or walking underwater.
  • FIG. 1 is a view illustrating general flippers.
  • FIG. 2 is a side view illustrating a state of wearing flippers worn with shoes according to one embodiment of the present disclosure.
  • FIG. 3 is a front view illustrating a fin portion of the flippers worn with shoes according to one embodiment of the present disclosure.
  • FIG. 4 is a cross-sectional view illustrating a cross section taken along line A-A of FIG. 3 .
  • FIG. 5 is a side view illustrating a folded state of the fin portion of the flippers worn with the shoe according to one embodiment of the present disclosure.
  • FIG. 6 is a view illustrating a state when swimming with flippers worn with shoes according to one embodiment of the present disclosure.
  • Flippers worn with shoes according to the present disclosure for achieving such an object can be used as a flipper function by wearing a plate-shaped fin portion on the front of a shin, or can accommodate the flipper by folding a portion of the fin portion on a foot of a shoe. Accordingly, the flippers can be easily used both in and out of water.
  • FIG. 2 is a side view illustrating a state of wearing flippers worn with shoes according to one embodiment of the present disclosure
  • FIG. 3 is a front view illustrating a fin portion of the flippers worn with shoes according to one embodiment of the present disclosure
  • FIG. 4 is a cross-sectional view illustrating a cross section taken along line a-a of FIG. 3 .
  • Each of the flippers worn with the shoe according to the embodiment of the present disclosure includes a fin portion 100 , a shoe portion 200 , and a fastening portion 300 .
  • the fin portion 100 is worn on the front of a shin of a user, and the entire outline of a body 110 is formed in a trapezoidal plate shape having a short upper side.
  • a height of the trapezoidal body 110 should be formed smaller than a height of a knee bone when wearing a shoe. If the height of the body 110 is higher than the height of the knee bone, it may cause discomfort to walk when folded.
  • the height of the body 100 is similar to a height of the shoe, but may be set to a height that does not interfere with walking. It is confirmed that lift is generated even with a width of the fin placed on the left and right sides of the shoe.
  • the body 110 is cut upward from a center of the lower side of the trapezoidal shape to a size corresponding to the width of the shoe portion 200 to form the instep seating part 120 .
  • the instep seating portion 120 has a width corresponding to the width of the shoe portion 200 , and a height thereof is set to correspond to a height of an instep of the shoe portion 200 , and thus the shoe portion 200 is coupled with the fin portion 100 in a state in which a position corresponding to the instep is inserted into the instep seating portion 120 .
  • An end portion of the instep seating portion 120 is coupled to the shoe portion 200 using an adhesive or sewing.
  • the fin portion body 110 includes a plurality of protrusions 140 to form a groove along a longitudinal direction.
  • the protrusion 140 may guide a flow of water to reduce on a drag applied to the fin pin portion 110 when the user paddles with feet in water with wearing the flippers. This reduces burden on the ankles and legs of the user and reduces risk of fatigue and injury.
  • a fold line 111 is formed to be perpendicular to a longitudinal direction of the body 110 of the fin portion 110 .
  • the fold line 111 has a thickness smaller than that of other portions of the body 110 . Accordingly, the fin portion body 110 is folded to be perpendicular to the longitudinal direction and can be attached and folded to the shoe portion 200 .
