Description

Technical Field

[0001] This utility model relates to a business shoe that is easy to run in. Background Technology

[0002] Business shoes are a type of footwear characterized by a simple and comfortable design philosophy, meeting the needs of everyday wear. The concept, connotation, and function of business shoes are closely related to this new lifestyle ideal. While business shoes are formal in appearance, they also offer comfort. However, because business shoes often use leather to emphasize their formality, they tend to be stiff overall. Additionally, the soles often have poor rebound and a rigid shape, affecting comfort. For business professionals engaged in sales, business development, and other similar work, their daily routines may involve visiting clients in the city, traveling between the office and client companies, and sometimes requiring short stretches of rapid movement or even jogging. A comfortable pair of business shoes would greatly enhance the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a business shoe that is easy to run in. It has a simple structure, is comfortable to wear, has good sole rebound performance, provides stable support, and offers a good wearing experience.

[0004] To achieve the above objectives, this utility model provides a business shoe that is easy to run in, including a sole. The sole includes a forefoot portion, an arch portion, and a heel portion. The forefoot portion is connected to the heel portion through the arch portion. The sole has continuous filling cavities corresponding to the forefoot portion, arch portion, and heel portion. The filling cavities are filled with PU foam. The PU foam includes an inner lining portion and an outer surrounding portion. The outer surrounding portion surrounds the inner lining portion. The inner lining portion is positioned corresponding to the heel portion. The hardness of the inner lining portion is greater than that of the outer surrounding portion. The inner lining portion is columnar.

[0005] The beneficial effects of this design are as follows: The relatively soft material used in the overlay provides a relaxed feel when stepping on the foot. During daily walking or exercise, the overlay easily cushions the impact of the ground, providing gentle support as if stepping on a comfortable cushion, effectively reducing foot fatigue. This relaxed feel is especially beneficial during prolonged standing or walking, enhancing the user's comfort and overall wearing experience. The inner lining, the core support component of the design, is columnar and harder than the overlay, specifically designed for the heel area. This design effectively prevents heel collapse. During running or exercise, the foot experiences significant impact and pressure upon landing, particularly concentrated on the heel. The firmer inner lining effectively resists this pressure, maintaining heel stability and the shape of the sole, preventing heel collapse and deformation due to excessive pressure, thus providing reliable foot support. This not only protects the foot joints and reduces the risk of injury, but also provides a stable point of force for every start, acceleration and landing, allowing users to enjoy various sports more fully and improve athletic performance. Whether it is daily jogging or high-intensity running, this sole can provide wearers with both comfort and safety, greatly optimizing the sports experience.

[0006] As a further feature of this invention, a footrest is formed on the heel portion, the inner part is disposed in the footrest, and a plurality of deformation grooves are formed on the outer peripheral wall of the footrest.

[0007] The beneficial effects of this design are as follows: the footrest provides a stable point of support for the foot, while the inner lining ensures wearing comfort. Particularly noteworthy are the deformation grooves on the outer wall of the footrest, which offer excellent functionality. When the foot applies pressure to the sole, these grooves guide the sole material through orderly compression and deformation, effectively distributing pressure, preventing excessive localized pressure, and improving the overall cushioning performance of the sole. Furthermore, after the pressure dissipates, these carefully designed grooves utilize the elasticity of the sole material to guide the sole to quickly and accurately return to its original state, ensuring the reliability and stability of the sole during repeated stress, allowing the shoe to consistently provide stable support for the foot.

[0008] As a further feature of this invention, the sole is provided with a supporting edge along the circumference of the filling cavity, and a plurality of supporting ribs are formed on the heel between the deformation groove and the supporting edge, arranged along the height direction of the sole.

[0009] The beneficial effects of this design are as follows: During walking or running, when the heel strikes the ground, the body weight causes the deformation grooves in the sole to deform. Support ribs then stably support the area around the heel along the sole's height. On one hand, these ribs effectively limit excessive deformation of the deformation grooves, preventing permanent collapse or deformation of the sole due to frequent pressure and maintaining the integrity of the sole structure. On the other hand, after the pressure is released, these support ribs, with their elasticity and rigidity, quickly push the deformation grooves back to their original shape, ensuring the sole can quickly and accurately return to its original position, preparing for the next landing. This efficient deformation recovery mechanism not only ensures good shoe performance but also provides continuous and stable support for the wearer, reducing instability and discomfort caused by sole deformation, making every step easier and more comfortable.

[0010] As a further feature of this invention, a support plate is provided at the arch of the foot, with one end of the support plate extending forward to the forefoot and the other end extending towards the heel.

[0011] The beneficial effects of this design are as follows: It plays a crucial supporting role during walking, standing, and exercise, significantly optimizing foot support. When the wearer is standing, the support plate precisely conforms to the arch curve, evenly distributing body weight, effectively reducing arch pressure and preventing flat feet and other arch-related fatigue and pain. During walking or running, the section extending towards the forefoot provides additional support and stability with each stride, helping to make each step smoother and more powerful, while reducing discomfort caused by excessive pressure on the forefoot. The end extending towards the heel provides strong support and cushioning when the heel lands, absorbing impact and protecting the heel and ankle joints. This allows the wearer to experience comprehensive comfort and safety whether walking for extended periods or engaging in various sports, significantly improving overall foot support performance and wearing experience.

[0012] As a further feature of this invention, the support piece is embedded in the PU foam, and the two sides of the support piece are smoothly connected to the PU foam through arc-shaped surfaces.

[0013] The beneficial effects of this design are as follows: This combination allows the support piece to better utilize its mechanical properties. The two sides of the support piece are smoothly connected to the PU foam through carefully designed curved surfaces. These curved surfaces not only increase the contact area between the support piece and the foam, but also make the force transmission more evenly distributed, avoiding stress concentration points and effectively improving the overall structural stability. When the wearer is standing, the support piece can precisely provide just the right amount of support for key areas such as the arch, heel, and ball of the foot according to the physiological curve of the foot, effectively relieving foot pressure and reducing fatigue. During walking or running, such as walking, running, and jumping, the support piece can quickly respond to the dynamic changes of the foot, providing stable support and preventing excessive twisting or deformation of the foot, greatly improving wearing comfort and athletic performance, making every step more stable and powerful.

[0014] As a further feature of this invention, the contact surface between the support sheet and the PU foam is provided with a wave pattern, and the contact surface between the PU foam and the support is provided with a tooth pattern that matches the wave pattern.

[0015] The benefits of this design are as follows: It ensures a secure connection between the support plate and the PU foam, and the wave-like and serrated textures greatly enhance the friction and bonding force between them. This special texture design effectively disperses and cushions the force of pedaling, preventing relative displacement or deviation between the support plate and the foam due to impact or continuous high-frequency vibration. Even under prolonged, high-intensity walking or running conditions, it maintains a tight and stable connection, providing a stable, safe, and comfortable pedaling experience.

[0018] This utility model provides an embodiment of a business shoe that is convenient for running, such as... Figures 1 to 2As shown, the shoe includes a sole 1, which comprises a forefoot portion 13, an arch portion 12, and a heel portion 11. The forefoot portion 13 is connected to the heel portion 11 via the arch portion 12. Continuous filling cavities are formed on the sole 1 corresponding to the forefoot portion 13, arch portion 12, and heel portion 11. These cavities are filled with PU foam 3. The PU foam 3 includes an inner lining portion 31 and a surrounding portion 32. The surrounding portion 32 surrounds the inner lining portion 31. The inner lining portion 31 is positioned corresponding to the heel portion 11 and has a higher hardness than the surrounding portion 32. The inner lining portion 31 is columnar. The advantage of this design is that the surrounding portion 32, made of a relatively soft material, provides the user with a relaxed walking feel. During daily walking or exercise, the surrounding part 32 easily cushions the impact from the ground when the foot lands, providing gentle support to the foot, as if stepping on a comfortable cushion, effectively reducing foot fatigue. This relaxed feel is especially beneficial during prolonged standing or walking, enhancing the user's comfort and wearing experience. The inner lining 31 is the core support component of the entire design. Its columnar shape and greater rigidity than the surrounding part 32, specifically designed to support the heel 11, effectively prevents heel collapse. During running or exercise, the foot experiences significant impact and pressure upon landing, particularly concentrated on the heel 11. The higher rigidity of the inner lining 31 effectively resists this pressure, maintaining heel stability and the shape of the sole 1, preventing heel collapse and deformation due to excessive pressure, thus providing reliable foot support. This not only protects the foot joints and reduces the risk of injury, but also provides a stable point of force for every start, acceleration and landing, allowing users to enjoy various sports more and improve athletic performance. Whether it is daily jogging or high-intensity running, this sole 1 can bring the wearer both comfort and safety, greatly optimizing the sports experience.

[0019] As a further feature of this embodiment, a footrest is formed on the heel portion 11, and the inner lining 31 is disposed within the footrest. A plurality of deformation grooves 111 are formed on the outer peripheral wall of the footrest. The beneficial effect of this arrangement is that the footrest provides a stable point of force for the foot, while the placement of the inner lining 31 within it ensures wearing comfort. Particularly noteworthy are the deformation grooves 111 on the outer peripheral wall of the footrest, which exhibit excellent functional performance. When the foot applies pressure to the sole 1, the deformation grooves 111 guide the sole 1 material to undergo orderly compression deformation, thereby more effectively dispersing pressure, avoiding excessive local pressure, and improving the overall cushioning performance of the sole 1. Moreover, after the pressure disappears, these carefully designed deformation grooves 111 utilize the elasticity of the sole 1 material itself to guide the sole 1 to quickly and accurately return to its original state, ensuring the reliability and stability of the sole 1 during repeated stress processes, allowing the shoe to consistently provide stable support for the foot.

[0020] As a further feature of this embodiment, the sole 1 is provided with a support edge 14 along the circumference of the filling cavity, and a plurality of support ribs 112 are formed on the heel portion 11 between the deformation groove 111 and the support edge 14, arranged along the height direction of the sole 1. The beneficial effects of this arrangement are as follows: During walking or running, when the heel lands, the weight of the body causes the deformation groove 111 of the sole 1 to deform. The support ribs 112 can stably support the area around the heel along the height direction of the sole 1. On the one hand, they can effectively limit the excessive deformation of the deformation groove 111, preventing the sole 1 from permanently collapsing or deforming due to frequent pressure, and maintaining the structural integrity of the sole 1. On the other hand, after the pressure is released, these support ribs 112, with their own elasticity and rigidity, quickly push the deformation groove 111 back to its original shape, ensuring that the sole 1 can quickly and accurately reset, preparing for the next landing. This efficient deformation recovery mechanism not only ensures the shoe's excellent performance but also provides continuous and stable support for the wearer, reducing instability and discomfort caused by sole deformation, making every step easier and more comfortable.

[0021] As a further feature of this embodiment, a support plate 2 is provided at the arch portion 12. One end of the support plate 2 extends towards the forefoot portion 13, and the other end extends towards the heel portion 11. The beneficial effects of this design are: it plays a crucial supporting role during walking, standing, and exercise, greatly optimizing the support effect on the foot. When the wearer is standing, the support plate 2 can precisely conform to the arch curve, evenly distributing body weight, effectively reducing arch pressure, and preventing flat feet and other arch-related fatigue and pain problems. During walking or running, the portion extending towards the forefoot portion 13 provides additional support and stability to the forefoot as the stride progresses, helping each step to be smoother and more powerful, while reducing discomfort caused by excessive force on the forefoot. The end extending towards the heel portion 11 provides strong support and cushioning when the heel lands, absorbing impact and protecting the heel and ankle joints. This allows the wearer to experience comprehensive comfort and safety whether walking for extended periods or engaging in various sports, significantly improving the overall foot support performance and wearing experience.

[0022] As a further feature of this embodiment, the support piece 2 is embedded in the PU foam 3, and the two sides of the support piece 2 are smoothly connected to the PU foam 3 through curved surfaces. The beneficial effect of this design is that this combination allows the support piece 2 to better utilize its mechanical properties. The carefully designed curved surfaces on both sides of the support piece 2 smoothly connect to the PU foam, increasing the contact area between the support piece 2 and the foam, making the force transmission more evenly distributed, avoiding stress concentration points, and thus effectively improving the stability of the overall structure. When the wearer stands, the support piece 2 can precisely provide appropriate support to key areas such as the arch, heel, and ball of the foot according to the physiological curve of the foot, effectively relieving foot pressure and reducing fatigue. During walking or running, such as walking, running, and jumping, the support piece 2 can quickly respond to the dynamic changes of the foot, providing stable support, preventing excessive twisting or deformation of the foot, greatly improving wearing comfort and athletic performance, making every step more stable and powerful.

[0023] As a further feature of this embodiment, the contact surface between the support plate 2 and the PU foam 3 is provided with a wave-like pattern, and the contact surface between the PU foam 3 and the support plate is provided with a toothed pattern that matches the wave-like pattern. The beneficial effect of this design is that it ensures a stable connection between the support plate 2 and the PU foam 3, and the wave-like pattern and toothed pattern greatly enhance the friction and bonding force between them. This special texture design effectively disperses and buffers the force of foot pedaling, preventing relative displacement or deviation between the support plate 2 and the foam due to impact or continuous high-frequency vibration. Even under prolonged, high-intensity walking or running conditions, it maintains a tight and stable connection, thus providing a stable, safe, and comfortable pedaling experience.

[0024] The above examples are merely one preferred embodiment of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution are all included within the protection scope of this utility model.
