[0005] Main working principle: the diversion frog leg is provided with a shoe body, a paddle body and a diversion port in the paddle body to realize more efficient water flow utilization and propulsion generation. Among them, the user puts the foot into the shoe cavity, and the space jointly enclosed by the shoe face, the shoe head and the shoe sole can comfortably accommodate the foot and provide necessary support and protection. When the user kicks the leg, the paddle body will generate thrust in the water. Due to the design of the diversion port, the water flow can pass through the paddle body more efficiently, reducing the loss of energy. When the user is active underwater, especially when swimming or diving and other actions that require propulsion, the water flow will flow along the shape of the paddle body. The design of the diversion port is the key. It extends along the length direction of the paddle body, gradually extending from the side facing the shoe face to the side facing the shoe sole. This design makes the water flow flow along a smoother path after entering the diversion port, reducing turbulence and resistance. The diversion port also plays a role in guiding water flow, so that the water flow can more concentratedly act on the specific area of the paddle body, thereby improving the propulsion efficiency. The existence of the diversion port also makes the paddle body maintain good water flow utilization efficiency in different stages of kicking action. Stability and comfort:
[0006] In summary, the frog foot of the utility model realizes more efficient water flow utilization and propulsion force generation through the unique paddle body design and the flow guide opening.
[0007] As preferred, the paddle body comprises a first plate surface, a second plate surface and a reset baffle;

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] Example 1
[0029] This embodiment discloses a guide frog foot, such as Figures 1-2 As shown, the shoe includes a shoe body 1, a paddle 2, and a sole 12. The user inserts their foot into the shoe cavity 13, where the space formed by the upper 10, toe box 11, and sole 12 comfortably accommodates the foot and provides necessary support and protection. When the user performs a kicking motion, the paddle 2 generates thrust in the water. Due to the design of the guide port 20, water flows more efficiently through the paddle 2, reducing energy loss. When the user is active underwater, especially performing propulsion actions such as swimming or diving, the water flows along the shape of the paddle 2. The design of the guide port 20 is crucial. It extends along the length of the paddle 2, gradually extending from the side facing the upper 10 to the side facing the sole 12. This design allows the water to flow along a smoother path after entering the guide port 20, reducing turbulence and drag. The guide port 20 also guides the water flow, allowing it to act more concentratedly on specific areas of the paddle 2, thereby improving propulsion efficiency. The presence of the guide port 20 also ensures that the paddle body 2 maintains good water flow utilization efficiency at different stages of the kicking motion. Stability and comfort:
[0030] In summary, the guide frog foot of this invention achieves more efficient water flow utilization and propulsion generation through the unique design of the paddle body 2 and the setting of the guide port 20. At the same time, the design of the shoe body 1 also ensures stability and comfort when wearing it, allowing users to move more freely during underwater activities.
[0031] In some alternative embodiments, the combined design of the reset barrier 23, the first plate surface 21, and the second plate surface 22 enables the paddle body 2 to remain stable during kicking, while the design of the flow guide 20 further improves water flow utilization efficiency. The reset barrier 23 is mainly designed to help the paddle body 2 to quickly reset after the kicking action is completed. When the paddle body 2 kicks forward, the reset barrier 23 will store energy like a spring; when the paddle body 2 needs to reset, the stored energy will be released to push the paddle body 2 back to the initial position more quickly. The structural stability and water flow utilization efficiency of the paddle body 2 are enhanced. The reset speed and efficiency of the paddle body 2 are improved, enabling the user to maintain higher propulsion during continuous kicking.
[0032] The energy loss of the paddle body 2 during the reset process is reduced, and the overall movement efficiency is improved.
[0033] In some alternative embodiments, the main function of the reinforcing barriers 24 is to enhance the structural strength of the paddle body 2, but they also indirectly enhance the reset capability of the paddle body 2. The reinforcing barriers 24 separate the flow guide 20 into multiple independent flow channels, which not only improves water flow utilization efficiency but also makes the paddle body 2 more uniform when under stress. When the paddle body 2 is subjected to external forces, the reinforcing barriers 24 can disperse these forces to prevent the paddle body 2 from deforming or being damaged. At the same time, the reinforcing barriers 24 also increase the overall stiffness of the paddle body 2, making it more rapid and stable during reset. The structural strength and stiffness of the paddle body 2 are enhanced, improving its durability and damage resistance. The paddle body 2 is more rapid and stable during reset, improving movement efficiency.
[0034] In some alternative embodiments, the multiple reinforcing barriers 24 separate the flow guide 20 into multiple independent flow channels, making the water flow smoother when passing through the paddle body 2, reducing turbulence and resistance. Water flow utilization efficiency is further improved, and resistance is reduced.
[0035] In some alternative embodiments, the flow guide groove enables the water flow to flow more smoothly when passing through the paddle body 2, reducing the generation of turbulence and resistance. The smoothness of the water flow is improved, and the resistance is reduced.
[0036] In some alternative embodiments, the reinforcing reset rib 26 directly connects the bottom of the first plate surface 21 to the toe 11, providing an additional support point for the paddle body 2. During the reset process of the paddle body 2, the reinforcing reset rib 26 stores and releases energy like a spring, helping the paddle body 2 to return to the initial position more quickly. At the same time, it also increases the overall stiffness of the paddle body 2, preventing deformation during the reset process. The reset speed and stability of the paddle body 2 are significantly improved, enabling the user to maintain higher propulsion and efficiency during movement. The overall stiffness of the paddle body 2 is increased, improving its durability and deformation resistance.
[0037] In some optional embodiments, the cooperation of the fixing seat 14 with the shoelace enables the frog foot to be firmly fixed on the user's foot, preventing it from falling off or loosening when kicking, thereby improving the stability and safety of the frog foot.
[0038] In some optional embodiments, the hanging hole 15 is provided to facilitate the user to hang the frog foot for storage when not in use, thereby avoiding the problem of occupying too much space and improving the portability and storage convenience of the frog foot.
[0039] In some optional embodiments, the design of the anti-skid pattern 16 increases the friction between the sole 12 and the ground, preventing the user from slipping when moving underwater, thereby improving the safety of the user when moving underwater.
[0040] In some optional embodiments, the provision of the drainage port 17 can timely drain the accumulated water in the shoe cavity 13, keeping the foot dry and comfortable, thereby improving the comfort and dryness of wearing.
[0041] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
