Since the foot sleeve and the bottom face of the front paddling sole lie in the same horizontal plane, the swim fin of such a structure can only be used in a certain way, i.e. it is only suitable for use in the water, and cannot be reasonably used during leisure time (for example, walking on the shore and the like).
The swim fin is especially difficult to carry along and is therefore inconvenient, because the total length of the swim fin is too long.
In addition, the feeling of wearing the swim fin is terrible since the swim fin is injection moulded in one step using a rubber, and the swim fin is easy to fall off when it is tied loosely while the swim fin is uncomfortable to wear when it is tied tightly.
Although such a swim fin can realize the purpose of amphibious use, the folded structure has the shortcomings of a complex structure and being inconvenient to use.

Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the national phase entry of International Application No. PCT / CN2015 / 085088, filed on Jul. 24, 2015, which is based upon and claims priority to Chinese Patent Application No. 201410498796.8 filed on Sep. 25, 2014, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relaters to a shoe, and specifically relates to an amphibious swim fin which cannot only be used in diving but is also usable for walking on the shore.BACKGROUND[0003]A swim fin is an important device used by people in diving and enables a swimmer to exert a propelling force in a more effective way in the water by kicking legs. A common swim fin is composed of two parts: a foot sleeve (for fixing the swim fin on a dives foot) and a front paddling sole (providing the diver with a propelling force in the water). The foot sleeve and the front paddling sole of a traditional swim fin are formed as an insepa...
