Description

Technical Field

[0001] This application relates to the technical field of footwear, and more specifically, to a river tracing shoe. Background Technology

[0002] River tracing shoes are a type of athletic shoe that involves frequent entry and exit from water, requiring excellent drainage. Traditional designs typically employ perforated soles to achieve this: 3-8mm diameter through-holes are placed in areas such as the toe, arch, and heel, utilizing pressure differences during walking to drain water from the shoe cavity. While this approach ensures basic drainage efficiency, it introduces serious safety hazards. The perforated structure creates a direct channel through the sole, allowing sharp objects such as sand and broken glass to enter the shoe cavity through the drainage holes during river activities, causing soft tissue injuries to the foot. Utility Model Content

[0003] To address the problem that traditional water tracing shoes with through-hole drainage holes in the sole can easily cause soft tissue damage to the sole, this application provides a water tracing shoe.

[0004] A water tracing shoe includes a sole and an upper. The sole includes an upper and a lower sole. The upper is formed on the upper side of the upper sole. The upper surface of the upper sole has a recessed drainage groove that extends from one end of the upper sole to the other and is arranged around the edge of the upper surface of the upper sole. The lower surface of the upper sole has a recessed first water-passing groove, and the first water-passing groove and the drainage groove have a junction. The upper surface of the lower sole has a recessed fitting groove that matches the contour and size of the upper sole. The bottom surface of the lower sole has a recessed groove that matches the first water-passing groove. The water passage channel is a second water passage channel with the same structure. The upper bottom is embedded in the fitting groove of the lower bottom, and the lower surface and peripheral side of the upper bottom are in contact with the wall of the fitting groove. The upper bottom and the lower bottom are fixed together. The first water passage channel and the second water passage channel are positioned opposite each other to form a water passage channel. The upper bottom has a through hole at the junction of the first water passage channel and the drainage channel. The drainage channel and the water passage channel are connected through the through hole. The lower bottom has a side hole on its side, and the side hole is connected to the water passage channel.

[0005] Preferably, the insole, the top sole, and the upper are all made of EVA material, and the upper and the top sole are integrally formed.

[0006] Preferably, the front end of the sole is curved upwards, and the top surface of the sole gradually slopes downwards from the rear end to the starting position of the curve at the front end. The water passage is located at the starting position of the curve at the front end of the sole.

[0007] Preferably, the upper surface of the upper bottom is provided with a plurality of hemispherical protrusions at a position that avoids the drainage groove.

[0008] Preferably, the upper includes a toe cap for covering the toes, an arch cap for covering the arch of the foot, and a heel cap for covering the heel. The toe cap, arch cap, and heel cap are integrally formed, and an entry point for the foot to pass through is formed at the connection between the arch cap and the heel cap. Both the arch cap and the heel cap are provided with a plurality of ventilation holes.

[0009] Preferably, the bottom is fixed with an anti-slip rubber sheet covering its lower surface.

[0010] Preferably, the bottom surface of the anti-slip rubber sheet is provided with an anti-slip structure.

[0011] The beneficial technical effects of this application are as follows: the interlocking structure of the upper and lower soles forms a non-linear, meandering water passage. Compared with the traditional straight hole structure, this design blocks the reverse intrusion of foreign objects such as sand and broken glass through physical paths, significantly reducing the risk of soft tissue injury to the sole. The surrounding drainage groove on the edge of the upper surface of the upper sole utilizes the changes in foot pressure during walking to form a multi-directional water flow path, expanding the drainage coverage area. Furthermore, through the vertical connection design between the through hole and the water passage, combined with the negative pressure effect of the side hole outlet, a three-level drainage link is formed from the drainage groove to the through hole to the water passage to the side hole, significantly improving drainage efficiency.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1 and Figure 2 A type of river tracing shoe includes a sole and an upper 1. The sole includes an upper 2 and a lower 3. The upper 1 is formed on the upper side of the upper 2. The upper surface of the lower 3 is recessed with a fitting groove 31. The fitting groove 31 matches the outline and size of the upper 2. The upper 2 is embedded in the fitting groove 31 of the lower 3, and the lower surface and circumferential sides of the upper 2 are in contact with the wall of the fitting groove 31. The upper 2 and the lower 3 are fixed together by adhesive. The upper 2, the lower 3 and the upper 1 are all made of EVA material to ensure lightweight. The upper surface of the upper sole 2 is recessed with a drainage groove 21, which extends from one end of the upper sole 2 to the other end and is arranged around the edge of the upper surface of the upper sole 2. The drainage groove 21 has a semi-circular cross-section and a diameter of 3-4 mm. The lower surface of the upper sole 2 is recessed with a first water-passing groove 22, which has an interface with the drainage groove 21. The lower sole 3 has a second water-passing groove 32 with the same structure as the first water-passing groove 22 recessed on the bottom surface of the fitting groove 31. Both the first water-passing groove 22 and the second water-passing groove 32 have semi-circular cross-sections and extend along the width direction of the sole. A first water passage 22 and a second water passage 32 are aligned and connected to form a cylindrical water passage. There are multiple first water passages 22 and multiple second water passages 32, and multiple water passages are correspondingly provided. The diameter of each water passage is 3-4 mm. A through hole 23 is provided at the junction of the first water passage 22 and the drainage channel 21 on the upper bottom 2. The drainage channel 21 is connected to the water passage through the through hole 23. A side hole 33 is provided on the side of the lower bottom 3 corresponding to the position of each water passage. The side hole 33 is connected to the water passage, and the diameter of the side hole 33 matches the diameter of the water passage. In the above structure, the interlocking structure of the upper sole 2 and the lower sole 3 forms a non-linear, meandering water passage. Compared with the traditional straight hole 23 structure, this design blocks the reverse intrusion of foreign objects such as sand and broken glass through physical paths, significantly reducing the risk of soft tissue injury to the sole. The surrounding drainage groove 21 on the upper surface edge of the upper sole 2 utilizes the changes in foot pressure during walking to form a multi-directional water flow path, expanding the drainage coverage area. Through the vertical connection design between the through hole 23 and the water passage, combined with the negative pressure effect of the side hole 33 outlet, a three-level drainage link is formed from the drainage groove 21 to the through hole 23 to the water passage to the side hole 33, significantly improving drainage efficiency.

[0018] Reference Figure 1 and Figure 2, Further, a plurality of transverse grooves 24 are recessed on the upper surface of the upper base 2. The plurality of transverse grooves 24 extend along the width of the upper base 2. The number of the transverse grooves 24 matches the number of the water channels. And the plurality of transverse grooves 24 are aligned with the plurality of water channels one by one. At least one through hole 25 is provided on the upper base 2 for each transverse groove 24. The transverse groove 24 is connected to the water channel through the through hole 25. Both ends of the plurality of transverse grooves 24 penetrate through the drain groove 21. And communication grooves 26 are recessed on both side edges of the upper surface of the upper base 2. The ends of the plurality of transverse grooves 24 are connected through the communication grooves 26. The cross sections of the transverse grooves 24 and the communication grooves 26 are both semi-circular with a diameter of 3-4 mm. The drainage coverage area is further enlarged through the transverse grooves 24 and the communication grooves 26 to achieve rapid drainage.

[0019] Refer to Figure 1 and Figure 2 , Further, a first semi-surrounding groove 27 in a "C" shape is recessed on the lower surface of the upper base 2, and a second semi-surrounding groove 34 in a "C" shape is recessed on the upper surface of the lower base 3. The number of the first semi-surrounding grooves 27 may be equal to or less than the number of the first water through grooves 22. Each first semi-surrounding groove 27 has a corresponding first water through groove 22 connected thereto to form a fully enclosed structure. The number of the second semi-surrounding grooves 34 may be equal to or less than the number of the second water through grooves 32. Each second semi-surrounding groove 34 has a corresponding second water through groove 32 connected thereto to form a fully enclosed structure. And the number of the first semi-surrounding grooves 27 is equal to the number of the second semi-surrounding grooves 34. And each first semi-surrounding groove 27 has a second semi-surrounding groove 34 aligned therewith to form a cylindrical groove. The aperture of the cylindrical groove is equal to the aperture of the water channel. The diversion path of the water channel is enlarged through the cylindrical groove to further achieve rapid drainage. And the fully enclosed structure formed by the cylindrical groove and the water channel reduces the side holes 33, avoiding excessive side holes 33 from damaging the side support strength of the lower base 3.

[0020] Refer to Figure 1 and Figure 2 , Further, the front end of the sole is provided with an upward warping. The top surface of the sole gradually inclines downward from the rear end to the starting position of the warping at the front end. The water channels, the transverse grooves 24, and the communication grooves 26 are all arranged at the starting position of the warping at the front end of the sole. The warping curvature radius of the front end of the sole 1 is 10-50 mm, and the inclination angle of the top surface of the sole 1 is 1-5°. The upward warped front end of the sole conforms to the front end of the foot applying force when walking during human walking. The upward warped part of the front end of the foot makes the rear end of the sole quickly bounce up and fit to the human foot through the lever effect, making walking more comfortable. At the same time, the warping of the front end of the sole makes the top surface of the front end of the sole incline downward towards the starting position of the warping. And the gradual downward inclination of the sole from the rear end to the starting position of the warping at the front end makes the water naturally gather towards the water channels, the transverse grooves 24, and the communication grooves 26, achieving faster water drainage.

[0021] Reference Figure 1 and Figure 2 Furthermore, the upper surface of the upper sole 2 is uniformly provided with a number of hemispherical protrusions 28 at the position where it avoids the drainage groove 21, the transverse groove 24, and the connecting groove 26. The diameter of the protrusions 28 is 3-5mm. The protrusions 28 stimulate the acupoints on the sole of the foot and improve comfort. At the same time, the protrusions 28 increase the friction of the sole contact surface and reduce the discomfort caused by the human foot slipping on the top surface of the shoe sole.

[0022] Reference Figure 1 Furthermore, the upper 1 includes a toe wrap 11 for wrapping the toes, an arch wrap 12 for wrapping the arch of the foot, and a heel wrap 13 for wrapping the heel. The toe wrap 11, arch wrap 12, and heel wrap 13 are integrally formed, and an entry point 14 for the foot to enter is formed at the connection between the arch wrap 12 and the heel wrap 13. Both the arch wrap 12 and the heel wrap 13 are provided with a number of ventilation holes 15. The upper 1 wraps the various parts of the human foot more comfortably and is more convenient for outdoor walking. The ventilation holes 15 enable air circulation, facilitate quick drying of the shoes, and reduce the growth of bacteria.

[0023] Reference Figure 3 Furthermore, the bottom sole 3 is glued and fixed with an anti-slip rubber sheet 35 covering its lower surface. The bottom surface of the anti-slip rubber sheet 35 is provided with an anti-slip structure 351. The anti-slip structure 351 includes several wavy stripes 3511 provided on the anti-slip rubber sheet 35 at the corresponding toe area, and several anti-slip protrusions 3512 at other parts. The anti-slip rubber sheet 35 and the anti-slip structure 351 enhance the grip of the shoe in a stream environment.
