Abstract

An improved flipper comprises an outsole (1), a midsole (2) and a vamp (3) that are fixedly connected in sequence from the bottom to the top. The shape and the size of the outsole (1) match the shape and the size of a foot of a human body. The midsole (2) comprises a supporting portion (21) matching the outsole (1) in shape and size, and comprises a web-shaped water webbing portion (22) that extends outwards along the edge of a foot sole part of the supporting portion (21). The supporting portion (21) of the midsole (2) and the vamp (3) form an accommodating chamber accommodating the whole foot part of the human body. The web-shaped water webbing portion (22) comprises a first water webbing portion (221) and a second water webbing portion (222). One end of the first water webbing portion (221) is fixedly connected to the edge of the foot sole part of the supporting portion (21), and the other end of the first water webbing portion (221) is connected to one end of the second water webbing portion (222) by means of at least one foldable supporting mechanism (7).

Description

technical field [0001] The invention relates to a shoe, in particular to an improved flipper for amphibious use, which can be used for diving and walking on land. Background technique [0002] Fins are important equipment used by people in diving. It allows swimmers to get more effective propulsion in the water by kicking their legs. Generally, fins are covered by foot covers (used to fix fins on divers) Feet) and the webbed water forefoot (providing the diver's propulsion in the water) two parts; the foot cover and the webbed water forefoot of the traditional fins are an inseparable whole, and the bottom surface of the foot cover and the webbed water forefoot is in the The same horizontal plane is made of rubber one-time injection molding. Because the bottom surface of the fins with this structure is at the same level as the foot cover and the webbed water forefoot, the product has a single purpose and can only be used in water. When the body is idle (such as walking on la...
