Description

Technical Field

[0001] This utility model relates to the field of training shoe technology, and in particular to a training shoe with a removable pad. Background Technology

[0002] Training shoes are shoes worn by professional athletes when training reaction time and practicing basic movements. They are suitable for various sports and are also known as "all-around shoes." Training shoes generally consist of a sole and an upper. The upper is fixed to the sole, and a raised area is designed in the arch area of ​​the sole to reduce the contact area of ​​the sole, thereby maximizing explosive power and speed during exercise. Currently, the sole structure of training shoes is basically fixed, and the elasticity of the sole cannot be further adjusted according to the specific training program, limiting its application scenarios. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a training shoe with a removable pad. By opening a fixing groove laterally at the heel of the shoe, elastic pads with different support capabilities are inserted into the fixing groove, thereby improving the support capability of the shoe to meet the diverse needs of foot support at different stages of training. Users can flexibly replace the elastic pads according to their own training intensity and needs, further adjusting the hardness and resilience of the sole. Moreover, the whole process of replacing the elastic pads is quick and convenient.

[0005] This utility model provides a training shoe with a removable pad, including a sole and an upper connected to the sole. A fixing groove is opened laterally at the heel of the sole. A shock-absorbing component is disposed in the fixing groove. A removable elastic pad is also disposed in the fixing groove. The elastic pad is provided with a limiting groove and a locking entrance. The locking entrance is connected to the limiting groove and is located on the front side of the elastic pad. The shock-absorbing component is locked into the limiting groove through the locking entrance.

[0006] The sole and upper together form the basic structure of a training shoe. Building upon this, a horizontal groove is created at the heel of the shoe, into which elastic pads with varying support capabilities are inserted. This enhances the shoe's support, meeting the diverse foot support needs at different stages of training. Users can flexibly change the elastic pads according to their training intensity and needs, further adjusting the sole's hardness and resilience. Changing the elastic pads is quick and convenient. For example, during high-intensity jumping training, a stronger supportive elastic pad can be chosen to reduce impact damage to the joints; while during flexibility training, a softer elastic pad can be used to enhance the foot's contact with the ground. Furthermore, the precise fit of the limiting groove and the insertion point ensures that the elastic pads will not shift or fall off during exercise, effectively improving the safety and stability of the training shoe. Shock-absorbing components within the groove maintain the distance between the upper and lower soles, facilitating the insertion of the elastic pads.

[0007] In some embodiments, the fixing groove divides the sole into an upper sole and a lower sole. The shock-absorbing assembly includes an interlocking shock-absorbing sub-post and a shock-absorbing mother post. The upper sole extends downwards to provide the shock-absorbing sub-post, and the lower sole extends upwards to provide the shock-absorbing mother post. The shock-absorbing sub-post is inserted into the shock-absorbing mother post. Through the interlocking design of the shock-absorbing sub-post and the shock-absorbing mother post, the shock-absorbing assembly allows the sub-post to penetrate deeply into the shock-absorbing mother post when the sole is subjected to longitudinal pressure. The tight cooperation between the two effectively disperses the impact force, thereby providing more stable and elastic support for the foot.

[0008] In some embodiments, the upper end face of the shock-absorbing main column is provided with a downwardly recessed matching groove. The shock-absorbing sub-column is inserted into the shock-absorbing main column through the matching groove, and the diameter of the matching groove is adapted to the outer diameter of the shock-absorbing sub-column. The matching groove is used to fix the position of the shock-absorbing sub-column, so that the shock-absorbing components can be snapped together in the normal state, the gap between the upper and lower soles is stable, and with the elastic pad with a certain height, the stability of the sole is further enhanced.

[0009] In some embodiments, the lower end face of the shock-absorbing sub-post is provided with an upwardly recessed shock-absorbing groove, the lower end face of the shock-absorbing sub-post abuts against the bottom surface of the matching groove, and the bottom surface of the matching groove is also provided with a limiting protrusion, which is engaged in the shock-absorbing groove and adapted to the diameter of the shock-absorbing groove. The matching design of the limiting protrusion and the shock-absorbing groove not only enhances the connection stability between the shock-absorbing sub-post and the shock-absorbing mother post, preventing relative displacement between the two during movement, but also allows the sole to distribute stress more evenly when subjected to impact forces of different directions and intensities, protecting the user's feet from accidental injury. The cavity design inside the shock-absorbing groove allows air to enter the cavity, playing a supporting and cushioning role during sole compression.

[0010] In some embodiments, the elastic pad includes a carbon fiber plate area and a silicone rubber area. The outer contour of the carbon fiber plate area is adapted to the outer contour of the heel. The silicone rubber area is spliced ​​to the inner side of the carbon fiber plate area, and the silicone rubber area is provided with the limiting groove and the locking inlet. The carbon fiber plate area is made of high-strength carbon fiber material, which has excellent support and deformation resistance, and can effectively resist the lateral and longitudinal stress generated during exercise, ensuring the structural stability of the heel. The silicone rubber area is made of soft and elastic silicone material, which improves the shock absorption performance and facilitates the elastic pad to be locked into the fixing groove through the deformation of the silicone rubber area. It is understood that the manufacturer can adjust the strength of the carbon fiber material in the carbon fiber plate area to produce elastic pads with different elasticity and strength for users to replace, so that the training shoe can adapt to more training environments. Preferably, the carbon fiber plate area and the silicone rubber area are bonded together with adhesive.

[0011] In some embodiments, the limiting groove is sequentially connected with a first limiting ring and a second limiting ring from top to bottom. The diameter of the first limiting ring is adapted to the outer diameter of the shock-absorbing sub-post, and the diameter of the second limiting ring is adapted to the outer diameter of the shock-absorbing mother post. The diameter of the second limiting ring is larger than that of the first limiting ring. The design of the first and second limiting rings provides precise insertion guidance for the shock-absorbing sub-post and the shock-absorbing mother post, and also achieves precise adaptation of their outer diameters through the ring structure with different diameters. This further enhances the tightness and stability of the connection between the shock-absorbing component and the elastic pad. This layered limiting design also effectively prevents the shock-absorbing component from tilting or shifting due to uneven force during movement, ensuring the overall performance and service life of the sole.

[0012] In some embodiments, an auxiliary fixing plate extends upward from the rear side of the carbon plate area. The inner side of the auxiliary fixing plate is abutted against the edge of the upper sole. A positioning post extends forward from the auxiliary fixing plate, and a corresponding positioning groove is provided on the upper sole. The positioning post is inserted into the positioning groove. Through the tight fit between the inner side of the auxiliary fixing plate and the edge of the upper sole, and the precise insertion of the forward-extending positioning post into the corresponding positioning groove on the upper sole, a dual fixing mechanism for the elastic pad is formed, achieving precise adjustment and fixation of the pad's position.

[0013] In some embodiments, the upper and lower surfaces of the elastic pad are provided with dotted patterns. The dotted patterns further enhance the friction between the elastic pad and the upper and lower soles, effectively preventing slippage and fixing the position of the elastic pad.

[0014] In some embodiments, the arch area of ​​the sole is provided with an upwardly recessed raised groove, and a drainage groove is provided around the raised groove. In training shoes, the raised groove is designed in accordance with ergonomic principles, effectively supporting the arch and reducing foot fatigue caused by prolonged exercise. At the same time, the drainage groove surrounding the raised groove can quickly drain water in wet environments, maintain good contact between the sole and the ground, enhance grip, and prevent slipping.

[0015] In some embodiments, the sole surface is further provided with abrasion-resistant treads located on the front and rear sides of the elevation groove. During the actual wearing of the training shoe, the abrasion-resistant treads effectively increase the friction between the sole and the ground, allowing the user to be more stable and free during actions such as starting, stopping suddenly, and turning, reducing the risk of injury due to slipping. At the same time, its layout on the front and rear sides of the elevation groove not only makes full use of the sole space, but also works in conjunction with the elevation groove, drainage groove, and other structures to improve the overall performance of the shoe and meet the training requirements of athletes.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This invention improves the shoe's support by creating a horizontal fixing groove at the heel of the shoe and inserting elastic pads with different support capabilities into the groove. This allows the shoe to meet the diverse foot support needs at different stages of training. Users can flexibly replace the elastic pads according to their training intensity and needs to further adjust the hardness and resilience of the sole. The entire process of replacing the elastic pads is quick and convenient.

[0050] Reference Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the training shoe in some embodiments of this utility model.

[0051] According to some embodiments of the present invention, the present invention provides a training shoe with a detachable pad, including a sole 1 and an upper 2 connected to the sole 1. A fixing groove 3 is laterally opened at the heel of the sole 1. A shock-absorbing component 4 is disposed in the fixing groove 3. A detachable elastic pad 5 is also disposed in the fixing groove 3. The elastic pad 5 is provided with a limiting groove 53 and a locking entrance 54. The locking entrance 54 is connected to the limiting groove 53 and is located on the front side of the elastic pad 5. The shock-absorbing component 4 is locked into the limiting groove 53 through the locking entrance 54.

[0052] The sole 1 and upper 2 together form the basic structure of the training shoe. Based on this, a fixing groove 3 is horizontally opened at the heel of the shoe, and elastic pads 5 with different support capabilities are inserted into the fixing groove 3, thereby improving the shoe's support capacity to meet the diverse foot support needs at different stages of training. Users can flexibly replace the elastic pads 5 according to their training intensity and needs, further adjusting the hardness and resilience of the sole 1. The entire process of replacing the elastic pads 5 is quick and convenient. For example, during high-intensity jumping training, a more supportive elastic pad 5 can be selected to reduce impact damage to the joints; while during flexibility training, a softer elastic pad 5 can be used to enhance the foot's contact with the ground. Furthermore, the precise cooperation of the limiting groove 53 and the insertion point 54 ensures that the elastic pads 5 will not shift or fall off during exercise, effectively improving the safety and stability of the training shoe. The shock-absorbing component 4 set in the fixing groove 3 is used to maintain the gap between the upper and lower soles, facilitating the insertion of the elastic pads 5.

[0053] Reference Figure 2 , Figure 2 This is a schematic diagram of the bottom surface of the training shoe sole in some embodiments of this utility model.

[0054] According to some embodiments of this utility model, optionally, the arch of the sole 1 is provided with an upwardly recessed raised groove 14, and a drainage groove is provided around the raised groove 14. In training shoes, the design of the raised groove 14 conforms to ergonomic principles, effectively supporting the arch of the foot and reducing foot fatigue caused by prolonged exercise. At the same time, the drainage groove surrounding the raised groove 14 can quickly drain water in wet environments, maintaining good contact between the sole 1 and the ground, enhancing grip, and preventing slipping.

[0055] The sole 1 also features a wear-resistant tread pattern 15 on its bottom surface, located on both the front and rear sides of the elevation groove 14. During actual wear of the training shoe, the wear-resistant tread pattern 15 effectively increases the friction between the sole 1 and the ground, allowing the user to be more stable and free during actions such as starting, stopping suddenly, and turning, reducing the risk of injury due to slipping. At the same time, its layout on both sides of the elevation groove 14 makes full use of the space of the sole 1 and works in conjunction with the elevation groove 14, drainage groove, and other structures to improve the overall performance of the shoe and meet the training requirements of athletes.

[0056] Refer to 3-4, Figure 3 This is a side view of the rearfoot structure of a training shoe in some embodiments of the present invention; Figure 4 This is a top view of the heel of the training shoe in some embodiments of the present invention.

[0057] According to some embodiments of this utility model, optionally, the fixing groove 3 divides the sole 1 into an upper sole 11 and a lower sole 12. The shock-absorbing component 4 includes a shock-absorbing sub-post 41 and a shock-absorbing mother post 42 that interlock. The upper sole 11 has the shock-absorbing sub-post 41 extending downward, and the lower sole 12 has the shock-absorbing mother post 42 extending upward. The shock-absorbing sub-post 41 is inserted into the shock-absorbing mother post 42. Through the interlocking design of the shock-absorbing sub-post 41 and the shock-absorbing mother post 42, the shock-absorbing component 4 allows the shock-absorbing sub-post 41 to penetrate deep into the shock-absorbing mother post 42 when the sole 1 is subjected to longitudinal pressure. The close cooperation between the two effectively disperses the impact force, thereby providing more stable and elastic support for the foot.

[0058] The upper surface of the shock-absorbing main column 42 is provided with a downwardly recessed matching groove 421. The shock-absorbing sub-column 41 is inserted into the shock-absorbing main column 42 through the matching groove 421. The diameter of the matching groove 421 is adapted to the outer diameter of the shock-absorbing sub-column 41. The matching groove 421 is used to fix the position of the shock-absorbing sub-column 41, so that the shock-absorbing components 4 can be snapped together in the normal state, and the gap between the upper and lower soles is stable. With the help of the elastic pad 5 with a certain height, the stability of the sole 1 is further enhanced.

[0059] The lower end face of the shock-absorbing sub-post 41 is provided with an upwardly recessed shock-absorbing groove 411. The lower end face of the shock-absorbing sub-post 41 abuts against the bottom surface of the matching groove 421. The bottom surface of the matching groove 421 is also provided with a limiting protrusion 422. The limiting protrusion 422 is engaged in the shock-absorbing groove 411 and is adapted to the diameter of the shock-absorbing groove 411. The matching design of the limiting protrusion 422 and the shock-absorbing groove 411 not only enhances the connection stability between the shock-absorbing sub-post 41 and the shock-absorbing mother post 42, preventing relative displacement between the two during movement, but also allows the sole 1 to more evenly distribute stress when subjected to impact forces of different directions and intensities, protecting the user's feet from accidental injury. The cavity design inside the shock-absorbing groove 411 allows air to enter the cavity, playing a supporting and cushioning role during the compression of the sole 1.

[0060] The elastic pad 5 includes a carbon fiber plate area 51 and a silicone rubber area 52. The outer contour of the carbon fiber plate area 51 is adapted to the outer contour of the heel. The silicone rubber area 52 is spliced ​​to the inner side of the carbon fiber plate area 51. The silicone rubber area 52 is provided with a limiting groove 53 and a locking inlet 54. The carbon fiber plate area 51 is made of high-strength carbon fiber material, which has excellent support and deformation resistance, and can effectively resist the lateral and longitudinal stress generated during exercise, ensuring the structural stability of the heel. The silicone rubber area 52 is made of soft and elastic silicone material, which improves the shock absorption performance and facilitates the elastic pad 5 to be locked into the fixing groove 3 by the deformation of the silicone rubber area 52. It can be understood that the manufacturer can adjust the strength of the carbon fiber material of the carbon fiber plate area 51 to produce elastic pads 5 with different elasticity and strength for users to replace, so that the training shoe can adapt to more training environments. Preferably, the carbon fiber plate area 51 and the silicone rubber area 52 are bonded together with adhesive.

[0061] The limiting groove 53 is sequentially connected from top to bottom to a first limiting ring 531 and a second limiting ring 532. The diameter of the first limiting ring 531 is adapted to the outer diameter of the shock-absorbing sub-post 41, and the diameter of the second limiting ring 532 is adapted to the outer diameter of the shock-absorbing mother post 42. The diameter of the second limiting ring 532 is larger than that of the first limiting ring 531. The design of the first limiting ring 531 and the second limiting ring 532 provides precise insertion guidance for the shock-absorbing sub-post 41 and the shock-absorbing mother post 42. At the same time, the ring structure with different diameters achieves precise adaptation of the outer diameters of the two, further enhancing the tightness and stability of the connection between the shock-absorbing component 4 and the elastic pad 5. This layered limiting design also effectively prevents the shock-absorbing component 4 from tilting or shifting due to uneven force during movement, ensuring the overall performance and service life of the sole 1.

[0062] An auxiliary fixing plate 55 extends upward from the rear side of the carbon fiber plate area 51. The inner side of the auxiliary fixing plate 55 fits against the edge of the upper sole 11. A positioning post 56 extends forward from the auxiliary fixing plate 55, and a corresponding positioning groove 13 is provided on the upper sole 11. The positioning post 56 is inserted into the positioning groove 13. Through the tight fit between the inner side of the auxiliary fixing plate 55 and the edge of the upper sole 11, and the precise insertion of the forward-extending positioning post 56 into the corresponding positioning groove 13 of the upper sole 11, a dual fixing mechanism for the elastic pad 5 is formed, achieving precise adjustment and fixation of the pad's position.

[0063] The upper and lower surfaces of the elastic pad 5 are both decorated with dotted patterns. The dotted patterns further enhance the friction between the elastic pad 5 and the upper and lower soles, effectively preventing slippage and fixing the position of the elastic pad 5.
