It is produced.

Aqua shoes are equipment worn on the foot when swimming or in marine leisure activities such as skin scuba diving.

At this time, it is possible to obtain propulsion while wearing the flippers on the aqua shoes and spreading the foot while in the water while stirring back and forth.

Looking at the manufacturing method of these insoles for aqua shoes, the first step of applying a glue to the upper surface of the insole sheet in which a plurality of drainage holes are formed therein and stacking and fixing porous pads in which a plurality of holes are formed therein; The second step of forming a plurality of insole molded articles in the inside by pressing and molding the adhesive fixed insole sheet and the porous pad at high temperature through a press, and cutting the insole molded body formed in the insole sheet and the porous pad to complete the product. It is produced by the third step of manufacturing insoles.

However, due to the nature of the aqua shoes, the adhesive applied to the insole sheet melts in the process of press molding at high temperature through a press due to the structure in which a plurality of holes are formed in the porous pad. Since the insole is manufactured in the exposed state, when the shoes are worn, the adhesive exposed outside the insole frequently re-melts in the heat of the sole of the wearer, and in this case, not only causes discomfort of wearing, but also in the process of taking off the shoes There was a problem in that the insole was attached to the sole of the foot and detached from the shoe, making it very uncomfortable to wear and take off the shoe.

 Moreover, due to the adhesiveness exposed to the outside of the insole, there is a problem in that the wearer feels very low due to the heterogeneity felt when the shoe is worn.

In addition, in the process of press-molding to a high temperature through a press, the adhesive applied to the insole sheet is melted and frequently occurs when the drain hole formed in the insole sheet and the hole of the porous pad are closed, in this case through the insole. Since it was impossible to expect a smooth drainage function, the function as an insole for aqua shoes was lost, and there was a problem in that it was difficult to use the insole realistically.

In order to solve the problem of such aqua shoes, Korean Patent Registration No. 1862290 has a shoe body having an entrance opening on one side of the front surface; And a foldable flipper unit coupled to the shoe body, wherein the foldable flipper unit includes a unit housing provided in the shoe body; A button module that is slidably coupled to the unit housing and provided with a portion exposed outside the shoe body; A tunnel fixed in the shoe body in an area adjacent to the entrance opening; And one side is disposed in the unit housing is connected to the button module, the other side passes through the interior of the tunnel and includes a pull-out fin part for flippers that can be selectively slided out through the entrance opening of the shoe body, Corrugated rails are provided on both sides of the unit housing, and the button module is elastically slidably moved along the corrugated rails on both sides of the unit housing, and the button module is inserted into the upper frame of the corrugated rail and the frame Rail block having a rail that is moved along the longitudinal direction of; A plate spring connected to the rail block and elastically sliding on the corrugated rail; A button connection portion extending to one side of the rail block; An operation button coupled to an end of the button connection part and exposed to the outside of the shoe body; A pin portion connecting portion extending to the other side of the rail block and connected to a pull-out pin portion for flippers disposed in the unit housing; And a reinforcing pad coupled to the pull-out pin portion for flippers and connected to the pin portion connection portion, to provide a functional shoe having a foldable flipper unit.

However, in the prior art, there is a problem in that the gripping force of the shoe is vulnerable to slipping when the user walks.

In addition, the prior art has a problem in that the water is easily introduced into the shoe and the driving force is reduced when the user swims.
