[0020] Embodiments of the present invention include a shoe having a ribbed outsole and a notched midsole. We provide goods. The ribbed outsole and notched midsole support one foot. It achieves tuned flexibility and rigidity in multiple areas. The outsole is The outsole has multiple longitudinal ribs in one or more areas. Several implementations In terms of form, the longitudinal ribs are positioned on the upper surface of the outsole.

[0021] The midsole defines multiple notches configured to receive longitudinal ribs. In this embodiment, the midsole is positioned above the outsole, and the notch is located in the midsole. It is placed on the bottom surface of the wheel.

[0022] The interaction between the notch and the rib creates a region in which the knot and rib are located (for example, the foot). The sole (for example, the outsole) in the area from the midfoot to the forefoot below the metatarsal phalangeal joint (MTP) The core and / or midsole can be hardened. In some embodiments, the Replace the material volume of the rib and the outsole with the material volume of the rib and the outsole. The outsole can be made stiffer by adding a twist. Several implementations In this configuration, the interaction between the notches and ribs indirectly stiffens the midsole. The notches and ribs create a shape that facilitates rocking (i.e., from back to front). It is also possible. Therefore, footwear facilitates a faster transition to the forefoot, thereby It can enhance the propulsion phase of the wearer's movement. Flex adjustment using notches and ribs. The sole, which provides both flexibility and rigidity, is easy to manufacture and can be tailored to the specific wearer. It is also easy to customize and / or adjust.

[0023] In some embodiments, the footwear article 10, as shown in Figure 1 for example, has a forefoot section. The footwear article 10 comprises an upper, a midfoot region 12, a rearfoot region 14, and a rearfoot region 16. -18 may be provided. Any suitable upper may be used as upper 18. Good. The footwear article 10 comprises a sole 19 including a midsole 20 and an outsole 30. In some embodiments, the upper 18 is coupled to the midsole 20. For example, the upper 18 may be sewn, attached, or glued to the midsole 20. In some embodiments, the midsole 20 is coupled to the outsole 30. For example The midsole 20 may be directly attached to the outsole 30. Alternatively, the midsole The 20 may be bonded to the outsole 30 with adhesive. Dosole 20 is made from thermoplastic polyurethane foam particles (e-TPU).

[0024] In some embodiments, the midsole 20 is, for example, as shown in Figure 2. It is positioned above the outsole 30. The upper surface 34 of the outsole 30 is the midsole 20 It may correspond to the bottom surface 26. For example, the outsole 30 extends from the top surface 34 The midsole 20 may include one or more structural components, and the midsole 20 is relative to those structural components. One or more corresponding voids may be defined on the bottom surface 26.

[0025] In some embodiments, the outsole 30 has a longitudinal ridge extending from the upper surface 34. It is equipped with a rib 32. The longitudinal rib 32 is wider than the longitudinal rib 3 The length of 2 extends in the longitudinal direction of the footwear article 10 so that it increases. Several implementations In terms of form, the longitudinal rib 32 has a height that varies along its length (Figure 5). (See reference). For example, the upper surface of the longitudinal rib 32 is the center of the length of the longitudinal rib 32, or The height of the longitudinal rib 32 is at its maximum near the center, and the end of the longitudinal rib 32 is outsaw It may be curved, extending gradually downward toward the upper surface 34 of the ru 30. In one embodiment, the upper surface of the longitudinal rib 32 may be dome-shaped. This can contribute to a swaying function that promotes a faster transition to the forefoot, thereby enabling wear The propulsion phase of the movement of the vehicle is strengthened. For example, the curved shape of the longitudinal rib 32 enhances the propulsion phase. The MTP joint is the point where the transition of the forefoot towards propulsive toe-off occurs. When the longitudinal rib 32 is precisely positioned below, the foot rolls more quickly in the smallest possible manner. Supports the midsole 20 (for example) It has higher hardness than the e-TPU midsole, and combined with the curvature of the longitudinal ribs 32 A "mini" cradle may be formed. The cradle is more central from the peak of its unstable curvature. It naturally promotes displacement to a standing (stationary) position, and therefore the wearer's toes are off the ground. This assists in the process. Other shapes and heights can also be used for the longitudinal ribs 32.

[0026] The longitudinal ribs 32 are arranged at various locations on the upper surface 34 of the outsole 30. Alternatively, in some embodiments, the longitudinal rib 32 is located in the midfoot region 14. In some embodiments, the longitudinal rib 32 is located in the forefoot region 12. The rib 32 may extend from the midfoot region 14 to the forefoot region 12. For example, the longitudinal rib Bu 32 may be positioned below the metatarsal phalangeal joint (MTP) of the foot. Several embodiments In this configuration, the longitudinal rib 32 is provided only in the forefoot region 12. In some embodiments, The longitudinal ribs 32 are arranged separately in multiple regions. For example, the longitudinal ribs 32 One set is positioned in the midfoot region 14, and a second set of longitudinal ribs 32 is positioned in the rearfoot region. It may be arranged at 16. Other configurations are also possible. For example, in some embodiments, Outsol 30 may include diagonal ribs and / or transverse ribs. The diagonal and / or transverse ribs are located in the forefoot region 12 and the midfoot region 14. , and / or may be located in the rear foot region 16. Diagonal ribs and / or The transverse ribs correspond to the notches shown in Figures 9 and 10, as will be discussed below. It may be. In some embodiments, the longitudinal rib 32 extends from the rear foot region 16 forward. It extends into the foot region 12.

[0027] In some embodiments, the longitudinal ribs 32 are arranged parallel to each other. The set of b32 is as shown in Figure 3, for example, (e.g., midfoot region 14 and / Alternatively, they are spaced apart from each other across the width of the outsole 30 (of the forefoot area 12) This is also good. In some embodiments, the outsole 30 has at least three longitudinal ribs. It includes 32. For example, as shown in Figures 3 to 5, the outsole 30 has 5 It includes longitudinal ribs 32. Different numbers of longitudinal ribs 32 may be used (e.g. For example, two, four, or five or more. In some embodiments, the longitudinal rib 32 is located in front By being distributed across the width of the foot area 12, during compression and loading, the midsole This makes it easier to suppress the transverse displacement of the rib 20. For example, the longitudinal rib 32 is mid The bottom surface of the sole 20 is divided into narrower areas to restrict movement and displacement in the transverse direction. This may also be the case. In some embodiments, the transverse movement of the midsole across the sole and By somewhat limiting the displacement, during curved travel, sudden changes in direction (cuts), and This makes it easier to improve foot stability during sudden lateral braking.

[0028] In some embodiments, the longitudinal ribs 32 each have the same length. The longitudinal ribs 32 may have different lengths from each other. In some embodiments, The ends of the longitudinal ribs 32 are aligned with each other along the longitudinal direction of the footwear article 10. In some embodiments, the ends of the longitudinal ribs 32 may not be aligned. Good (see Figure 3).

[0029] In some embodiments, the longitudinal rib 32 is an integral part of the outsole 30. Therefore, the longitudinal rib 32 is integrally molded with the outsole 30. That is also good. Therefore, the ribbed outsole 30 is easy to manufacture.

[0030] In some embodiments, the upper surface 34 of the outsole 30 is flat except for the longitudinal ribs 32. It is flat. For example, the longitudinal rib 32 is (for example, transverse rib or other protruding structure) They are not interconnected. In some embodiments, the bottom surface 36 of the outsole 30 is No notches are defined on the opposite side of the longitudinal rib 32.

[0031] In some embodiments, the outsole 30 is as shown in Figures 3 to 5, for example. Next, the pattern of holes 38 that extend through the outsole 30 is determined. The holes 38 are arranged in rows. They may be arranged in a certain manner. For example, the row of holes 38 may be arranged between the longitudinal ribs 32. In some embodiments, the hole 38 differs in size and shape. For example, the hole 38 is... For example, it may be circular, square, rectangular, or elliptical.

[0032] In some embodiments, the midsole 20 is as shown in Figures 2, 6, and 7, for example. As shown, the notches 22 corresponding to the longitudinal ribs 32 are located on the bottom surface 2 of the midsole 20. The notch 22 is configured to fit complementaryly onto the longitudinal rib 32. Therefore, when the footwear article 10 is fully assembled (see Figure 1), the longitudinal rib 32 It is located within the notch 22. In some embodiments, the longitudinal rib 32 is located within the notch 22 This fully satisfies the requirements. In some embodiments, the longitudinal rib 32 located in the notch 22 Therefore, the sole assembly (e.g., outsole 30 and / or midsole 20) To harden. In some embodiments, this is achieved by adding ribs 32 and notches 22. As the sole hardens, the interaction between notch 22 and rib 32 affects the entire sole assembly. The body can be made stiff. In some embodiments, the midsole 20 is indirectly stiffened It may be done. When the longitudinal rib 32 is positioned below the MTP joint, complementary knots Chi 22 provides further stretch resistance in the longitudinal direction (of the wearer's walking), and It further assists the function of the foot ligaments in the metatarsal joint. With the longitudinal rib 32, the midsole The cushioning of the 20mm outsole can be soft and comfortable, while the 30mm outsole provides support during the walking propulsion phase. (By resisting elongation) more energy is generated than if the longitudinal ribs 32 were not present. - Stores and returns energy. By hardening the outsole 30, the wearer can run faster. The sole 19 allows for a faster transition to the forefoot during the wearer's walking cycle. It may be configured to promote this.

[0033] In some embodiments, the length of the notch 22 is greater than the width of the notch 22. It extends in the longitudinal direction of the footwear article 10 so that it becomes larger. In some embodiments, The groove 22 has a depth that varies along its length (see Figure 7). For example, The surface of the notch 22 is at the center of the notch 22's length, or approximately at the center, where the depth of the notch 22 is greatest. It becomes larger and gradually extends downward toward the bottom surface 26 of the midsole 20 at the end of the notch 22. It may be curved while in place. This configuration facilitates a faster transition to the forefoot. It can contribute to the swaying function, thereby enhancing the propulsion phase of the wearer's movement. For example Due to its curved shape, the longitudinal rib 32 allows for a more rapid response, as discussed above. The swaying of the feet is supported. Other shapes and depths can also be used for notch 22. .

[0034] The notches 22 may be located at various locations on the bottom surface 26 of the midsole 20. In some embodiments, the notch 22 is located in the midfoot region 14. In the configuration, the notch 22 is located in the forefoot region 12. The notch 22 is located in the midfoot region 1 4 may extend to the forefoot region 12. In some embodiments, the notch 22 is located in the forefoot It is located only in area 12. In some embodiments, the notch 22 is located in multiple areas. They are arranged in various places. For example, the first set of notches 22 is arranged in the midfoot area 14, and the notches A second set of the Chi 22 may be arranged in the hindfoot region 16. Other configurations are also possible. Example For example, in some embodiments, as shown in Figure 9, the midsole 120 is oblique It includes a combination of a directional notch 123 and a longitudinal notch 122. Several embodiments Then, the diagonal notch 123 is located in the forefoot region and / or as shown in Figure 9. It may be located in the rearfoot area. The diagonal notch 123 may also be located in the midfoot area. In some embodiments, the longitudinal notch 122 is located together with the oblique notch 123. It may be positioned in the hindfoot region. In some embodiments, it is shown, for example, in Figure 10. Thus, the midsole 220 includes transverse notches 223. Several implementations In this configuration, the transverse notch 223 is located in the forefoot region. 223 is similarly or alternatively located in the midfoot and / or rearfoot region. They may also be made. Diagonal notches 123, longitudinal notches 122, and transverse notches 2 23 arbitrary combinations are arranged in the midsole, and corresponding ribs are placed in the outsole. It may be arranged.
