[0061] Figure 1 An isometric exploded view of an exemplary embodiment of footwear item 100 is shown. For clarity, the exemplary embodiment is discussed below in the form of athletic shoes; however, it should be noted that the invention can take the form of any footwear item, including but not limited to: hiking boots, soccer cleats, American soccer cleats, athletic shoes, rugby shoes, basketball shoes, baseball shoes, and other types of shoes. Item 100 can also take the form of any non-athletic shoe, including but not limited to: dress shoes, casual shoes, sandals, and boots. Therefore, those skilled in the art will recognize that the concepts disclosed herein apply to a wide variety of shoe styles in addition to the specific styles discussed in the following material and illustrated in the figures. Figure 1As shown, footwear object 100, also referred to simply as object 100, is intended for use with the right foot; however, it should be understood that the following discussion can be equally applied to a mirror image of footwear object 100 intended for use with the left foot.

[0062] Reference Figure 1 For reference, object 100 can be divided into a forefoot portion 10, a midfoot portion 12, and a heel portion 14. The forefoot portion 10 can be generally associated with the toes and the joints connecting the metatarsals and phalanges. The midfoot portion 12 can be generally associated with the arch of the foot. Similarly, the heel portion 14 can be generally associated with the heel of the foot, including the calcaneus. Additionally, object 100 can include a lateral side 16 and a medial side 18. Specifically, the lateral side 16 and the medial side 18 can be opposite sides of object 100. Moreover, both the lateral side 16 and the medial side 18 can extend through the forefoot portion 10, the midfoot portion 12, and the heel portion 14.

[0063] It should be understood that the forefoot portion 10, midfoot portion 12, and heel portion 14 are intended for descriptive purposes only and are not intended to divide the object 100 into precise areas. Similarly, the outer side 16 and inner side 18 are intended to generally represent the two sides of the object, rather than precisely dividing the object 100 into two halves. In addition, the forefoot portion 10, midfoot portion 12, and heel portion 14, as well as the outer side 16 and inner side 18, should also be used for various components of the object, such as the sole structure and / or upper.

[0064] For consistency and convenience, directional adjectives are used throughout this embodiment corresponding to the illustrated embodiments. The term "longitudinal" as used throughout this embodiment and claims refers to a direction extending along the length or major axis of the object. In some cases, the longitudinal direction may extend from the forefoot portion of the object to the heel portion. Furthermore, the term "lateral" as used throughout this embodiment and claims refers to a direction extending along the width or minor axis of the object. In other words, the lateral direction may extend between the inside and outside of the shoe. Moreover, the term "vertical" as used throughout this embodiment and claims refers to a direction generally perpendicular to the lateral and longitudinal directions. For example, in the case where the object is placed flat on the ground, the vertical direction may extend upwards from the ground. Additionally, the term "proximal" refers to the portion of the shoe component closer to the foot when the footwear is worn. Similarly, the term "distal" refers to the portion of the shoe component further away from the foot when the footwear is worn. It should be understood that each of these directional adjectives can be used for various components of the object, such as the upper and / or sole structure.

[0065] Article 100 may include an upper 102 and a sole structure 110. Generally, the upper 102 can be any type of upper. In particular, the upper 102 can have any design, shape, size, and / or color. For example, in an embodiment where article 100 is a basketball shoe, the upper 102 may be a high-top upper shaped to provide high support at the ankle. In an embodiment where article 100 is a running shoe, the upper 102 may be a low-top upper.

[0066] The object 100 may include a sole structure 110. In some embodiments, the sole structure 110 may be configured to provide adhesive friction to the object 100. In addition to providing adhesive friction, the sole structure 110 may reduce ground reaction forces when compressed between the foot and the ground during walking, running, or other physical activities. The configuration of the sole structure 110 may vary significantly in different embodiments, thus including a variety of conventional or non-conventional structures. In some cases, the configuration of the sole structure 110 may be configured according to one or more ground types, and the sole structure 110 may be used on said one or more ground types. Examples of ground types include, but are not limited to: natural ground (e.g., grass), artificial ground (e.g., artificial turf), soil, and other surfaces.

[0067] The sole structure 110 extends between the foot and the ground when the object 100 is worn. In different embodiments, the sole structure 110 may include different components. For example, the sole structure 110 may include an outsole, a midsole, and / or an insole. In some cases, one or more of these components may be optional.

[0068] In some embodiments, footwear 100 may include a fastening system configured to tighten the upper 102. Typically, footwear 100 may be associated with any type of fastening system, including but not limited to: shoelaces, straps, zippers, hook-and-loop fasteners, and other types of fastening systems. In an exemplary embodiment, footwear 100 includes a lacing system comprising a lacing area 150 and shoelaces 152. Shoelaces 152 can be used to tighten the lacing area 150 to bring together the outer side 16 and inner side 18 of the upper 102.

[0069] Footwear items may include constructions for controlling the connection between the upper and the sole. In some embodiments, the upper may be selectively attached to various areas of the top of the sole. In other embodiments, the upper and sole may be attached using an intermediate connecting member. In an exemplary embodiment, the upper may be attached to the sole structure using a connecting member having one or more separate portions.

[0070] Now refer to Figure 1 and 2The footwear item 100 may include a connecting member 200. The connecting member 200 may generally be arranged between the upper 102 and the sole structure 110, and can be used to connect portions of the upper 102 to portions of the sole structure 110. Specifically, the current embodiment shows the connecting member 200 generally arranged between the upper 102 and the sole structure 110 at the midfoot portion 12, some portions of the forefoot portion 10, and the heel portion 14 of the item 100.

[0071] In some embodiments, the connecting member 200 may further include a layered structure. In some cases, the connecting member 200 may include two layers. In other cases, the connecting member 200 may include more than two layers. In one embodiment, the connecting member 200 may include an upper layer 202 and a lower layer 204.

[0072] Typically, the geometric properties of the upper layer 202 and the lower layer 204 can be varied. In some cases, the upper layer 202 and the lower layer 204 may have substantially planar geometries, such that the thickness of each layer is substantially less than the associated length and width of each layer. Additionally, in some cases, the upper outer perimeter 210 of the upper layer 202 and the lower outer perimeter 212 of the lower layer 204 may be shaped in a manner corresponding to the upper 102 and the sole structure 110.

[0073] In different embodiments, the dimensions of the upper layer 202 and / or the lower layer 204 may vary. In one embodiment, the upper layer 202 and the lower layer 204 may have substantially similar thicknesses. In another embodiment, the upper layer 202 may have a substantially greater thickness than the lower layer 204. In yet another embodiment, the lower layer 204 may have a substantially greater thickness than the upper layer 202. Moreover, in some cases, the lengths of the upper layer 202 and the lower layer 204 may be substantially similar. In other cases, the lengths of the upper layer 202 and the lower layer 204 may be substantially different. Moreover, in some cases, the widths of the upper layer 202 and the lower layer 204 may be substantially similar. In other cases, the widths of the upper layer 202 and the lower layer 204 may be substantially different. For example, in one embodiment, the upper layer 202 may be substantially wider than the lower layer 204 so that a portion of the upper layer 202 can wrap around the side of the upper 102.

[0074] The upper layer 202 and the lower layer 204 may be joined at a central attachment portion 220. Specifically, the central attachment portion 220 is a substantially narrow portion extending longitudinally through the connecting member 200. The upper layer 202 and the lower layer 204 may be attached using any method known in the art. In some cases, the upper layer 202 may be attached to the lower layer 204 by stitching. In other cases, the upper layer 202 may be attached to the lower layer 204 using some type of adhesive. It should be understood that the method of attaching the upper layer 202 to the lower layer 204 may be selected based on the material properties of the upper layer 202 and the lower layer 204 and the desired structural performance for the connecting member 200. In an exemplary embodiment, the upper layer 202 may be attached to the lower layer 204 using stitching 222.

[0075] The connecting member 200 may include one or more detachable portions. In the current embodiment, the connecting member 200 includes a first detachable portion 230 and a second detachable portion 232. The first detachable portion 230 extends generally laterally from the central attachment portion 220 to the outer side 16 of the connecting member 200. Furthermore, the first detachable portion 230 includes a first free portion 242 of the upper layer 202 and a first free portion 244 of the lower layer 204. The second detachable portion 232 extends generally laterally from the central attachment portion 220 to the inner side 18 of the connecting member 200. Furthermore, the second detachable portion 232 includes a second free portion 246 of the upper layer 202 and a second free portion 248 of the lower layer 204. With this arrangement, the first free portion 242 of the upper layer 202 can be configured to move substantially independently of the first free portion 244 of the lower layer 204. Similarly, the second free portion 246 of the upper layer 202 can be configured to move substantially independently of the second free portion 248 of the lower layer 204.

[0076] Figure 3 and 4 A cross-sectional view of an embodiment of the object 100 is shown. Specifically, Figure 3 An exploded cross-sectional view of object 100 is shown, while Figure 4 A cross-sectional view of object 100 is shown. (Refer to...) Figure 3 and 4 The upper layer 202 may be associated with the upper 102, while the lower layer 204 may be associated with the sole structure 110. In some embodiments, the upper surface 302 of the upper layer 202 may be attached to the lower surface 304 of the upper 102. Similarly, the lower surface of the lower layer 204 may be attached to the upper surface 308 of the sole structure 110.

[0077] In the current embodiment, the upper layer 202 is attached to the lower portion 310 of the upper 102 and the lower outer periphery 316 of the upper 102, which extends between the lower portion 310 and the first sidewall 312 and the second sidewall 314. Specifically, the first outer peripheral edge 250 and the second outer peripheral edge 252 of the upper layer 202 may be attached to the lower outer periphery 316 of the upper 102. Furthermore, the middle portion 254 (arranged between the first outer peripheral edge 250 and the second outer peripheral edge 252) may be attached to the lower portion 310. In some cases, the width of the upper layer 202 may be adjusted so that the first outer peripheral edge 250 and the second outer peripheral edge 252 are attached to the upper 102 at a higher position on the first sidewall 312 and the second sidewall 314. Moreover, the first outer peripheral edge 250 and the second outer peripheral edge 252 may be attached at different vertical heights along the first sidewall 312 and the second sidewall 314, respectively.

[0078] In one embodiment, the width of the lower layer 204 may be substantially similar to the width of the sole structure 110. However, in other cases, the width of the lower layer 204 may be less than the width of the sole structure 110. In still other cases, the width of the lower layer 204 may be greater than the width of the sole structure 110, such that a portion of the lower layer 204 can wrap around the sidewall 330 of the sole structure 110.

[0079] The upper layer 202 can be attached to the various parts of the upper 102 in any way. In some cases, the upper layer 202 can be bonded to the upper 102 using some type of adhesive. In other cases, the upper layer 202 can be sewn to the upper 102. In still other cases, some parts of the upper layer 202 can be attached to the upper 102 using adhesive, and other parts of the upper layer 202 can be attached to the upper 102 using stitching. Similarly, the lower layer 204 can be attached to the various parts of the sole structure 110 in any way. In some cases, the lower layer 204 can be bonded to the sole structure 110 using adhesive. In other cases, the lower layer 204 can be attached to the sole structure in some other ways, such as by using some type of fastener.

[0080] As discussed earlier, this arrangement provides partial separation between the upper 102 and the sole structure 110. In this case, the upper 102 and the sole structure 110 are connected by a central attachment portion 220 of the connecting member 200. Specifically, the middle portions 342 of the upper 102 and the sole structure 110 are directly connected to each other via the central attachment portion 220. However, the outward portions 344 of the upper 102 and the outward portions 346 of the sole structure 110 are attached to the first separation portion 230 and the second separation portion 232, and are therefore able to move partially independently of each other.

[0081] Articles with connecting members may include constructions for controlling the amount of separation between the upper and the sole. In some cases, the dimensions of the central attachment portion and the separation portion may be varied to adjust the separation characteristics of the article. For example, to achieve a high degree of separation, the central attachment portion may have a width that is substantially narrower than one or more separation portions of the connecting member.

[0082] In different embodiments, the width of the central attachment portion 220 can be varied. In this embodiment, the central attachment portion 220 has a width W1. Similarly, the first separation portion 230 has a width W2, and the second separation portion 232 has a width W3. Typically, the dimensions of widths W1, W2, and W3 can be varied to adjust the separation performance of the connecting member 200. In an exemplary embodiment, width W1 may be substantially smaller than width W2. In other words, the first separation portion 230 may be substantially wider than the central attachment portion 220. Additionally, in some cases, width W1 may be substantially smaller than width W3. In other words, the second separation portion 232 may be substantially wider than the central attachment portion 220. Moreover, when the upper 102 is attached to the sole structure 110 via the connecting member 200, a large portion of the upper 102 and the sole structure 110 can be separated from each other along the portion of the object 100 in which the connecting member 200 is used.

[0083] The dimensions discussed herein for the central attachment portion 220, the first separation portion 230, and the second separation portion 232 are for illustrative purposes only. In other embodiments, the widths of the central attachment portion 220, the first separation portion 230, and the second separation portion 232 can be varied in any way. For example, in another embodiment, the central attachment portion 220 may have a width substantially greater than that of the first separation portion 230 or the second separation portion 232. In another embodiment, the central attachment portion 220 may have a width substantially similar to that of the first separation portion 230 and / or the second separation portion 232. Moreover, while the current embodiment shows the first separation portion 230 and the second separation portion 232 having substantially equal widths, in other embodiments, the first separation portion 230 and the second separation portion 232 may have substantially different widths. For example, in another embodiment, the first separation portion 230 may be substantially wider than the second separation portion 232, which may provide a greater separation amount on the outer side 16 than on the inner side 18.

[0084] It should also be understood that the geometry and / or dimensions of the central attachment portion 220 may vary in different embodiments. In the current embodiment, the central attachment portion 220 has the shape of a relatively narrow longitudinal band with a substantially constant width. However, in other embodiments, the shape of the central attachment portion 220 may vary, and in some cases, the central attachment portion 220 may be provided with a width that varies along the length of the connecting member 200.

[0085] In some cases, the width W1 of the central attachment portion 220 may have a value that varies approximately between 1% and 10% of the total width of the connecting member 200. In other cases, the width W1 may have a value that varies approximately between 10% and 50% of the total width of the connecting member 200. In still other cases, the width W1 may have a value that varies approximately between 50% and 99% of the total width of the connecting member 200.

[0086] Figure 5 An isometric view of an embodiment of an object 100 is shown, the object 100 having a connecting member 200 shown in dashed lines. (Refer to...) Figure 5 The upper 102 and the sole structure 110 can be attached to the object 100 at different locations in different ways. In the current embodiment, the upper 102 and the sole structure 110 may be partially separated at the midfoot portion 12, and at some portions of the forefoot portion 10 and the heel portion 14. In this case, the upper 102 and the sole structure 110 are partially separated in the area where the connecting member 200 is present. In contrast, portions of the upper 102 and the sole structure 110 that are not associated with the connecting member 200 may be fully connected. For example, in this embodiment, the toe portion 502 of the object 100 is the portion where the upper 102 and the sole structure 110 are fully connected. In particular, the lower surface 304 of the upper 102 directly contacts the upper surface 308 of the sole structure 110. Moreover, the lower surface 304 of the upper 102 and the upper surface 308 of the sole structure 110 are firmly attached at the toe portion 502 across substantially the entire width of the object 100.

[0087] This arrangement, between the upper 102 and the sole structure 110, provides varying degrees of connection along different portions of the object 100. The portion of the upper 102 and sole structure 110 that is partially separated can be altered by adjusting the length of the connecting member 200. Similarly, the portion of the object 100 that is fully connected can be altered when the length of the connecting member 200 varies. For example, in an embodiment using a full-length connecting member extending through the entire length of the object, all portions of the upper 102 and sole structure 110 can be partially separated. In another embodiment, the connecting member may be arranged only in the forefoot portion of the object to limit the area of ​​partial separation between the upper and sole structures with respect to the forefoot portion.

[0088] Figure 6 and 7 This is a cross-sectional view of an embodiment of object 100. (Refer to...) Figure 6 and 7 The connecting member 200 provides partial separation between the upper 102 and the sole structure 110, which allows the upper 102 to be tilted or angled relative to the sole structure 110. When the upper 102 is tilted towards the inward side 18 (see...), Figure 6The first separation portion 230 can be opened. Specifically, the first free portion 242 of the upper layer 202 and the first free portion 244 of the lower layer 204 can be separated to allow the lower outer periphery 316 of the upper 102 and the upper outer periphery 604 of the sole structure 110 to move away from each other on the outer side 16. This configuration allows the upper 102 to roll inward 18. In addition, the second separation portion 232 is closed and compressed when force is transmitted to the inner side 18. Therefore, the force is absorbed by the connecting member 200. Moreover, the upper 102 and the sole structure 110 are allowed to partially separate to improve stability for the user.

[0089] In a similar manner, when the upper 102 is angled outwards towards the outside 16 (see...) Figure 7 When the upper 202 and the lower 204 are in contact, the second separation portion 232 can be opened. Specifically, the second free portion 246 of the upper 202 and the second free portion 248 of the lower 204 separate to allow the lower outer periphery 316 of the upper 102 and the upper outer periphery 604 of the sole structure 110 to move away from each other on the inner side 18. This configuration allows the upper 102 to roll outward 16. In addition, the first separation portion 230 is closed and compressed when force is transmitted to the outer side 16. Therefore, the force is absorbed by the connecting member 200. Moreover, the upper 102 and the sole structure 110 are allowed to partially separate to improve stability for the user.

[0090] The connecting member 200 provides a means of adjusting the width of the upper to accommodate feet of different sizes. In some cases, the upper can be separated from the sole structure to accommodate the size of the inserted foot, thereby improving the fit and comfort of the item.

[0091] Now refer to Figure 8 and 9 The object 100 is adjustable to change the foot width, particularly at the middle foot portion 12, where the foot width can be changed most for substantially similar foot sizes. Figure 8 In the first position shown, the width of the upper 102 is adapted to the width W4 of the first foot 802. Specifically, when the laces of the object 100 are tightened, the outer side 16 and inner side 18 of the upper 102 are pulled relatively closer. In this position, the width W4 can be substantially smaller than the width W5 of the sole structure 110. In other words, the lower outer periphery 316 of the upper 102 is substantially arranged inward of the upper outer periphery 604 of the sole structure 110. This may occur because the lower outer periphery 316 and the upper outer periphery 604 are not directly connected, but rather, on the contrary, are partially separated by a first separating portion 230 and a second separating portion 232.

[0092] exist Figure 9In the second position shown, the width of the upper 102 can accommodate the width W6 of the second foot 902. In this case, W6 is substantially larger than the width W4 because the second foot 902 is substantially wider than the first foot 802. Specifically, when the laces of the object 100 are tightened, the outer side 16 and inner side 18 of the upper 102 are pushed further apart to accommodate the greater width of the second foot 902. In this position, the width W6 can be substantially larger than the width W5 of the sole structure 110. In other words, the lower outer periphery 316 of the upper 102 is substantially arranged outward from the upper outer periphery 604 of the sole structure 110. Moreover, in this second position, the amount by which the upper 102 is positioned below the second foot 902 is greater than the amount by which the upper 102 is positioned below the first foot 802. This may occur because the lower outer periphery 316 and the upper outer periphery 604 are not directly connected, but rather, on the contrary, are partially separated by the first separating portion 230 and the second separating portion 232.

[0093] The objects of the embodiments discussed above can be made of materials known in the art for manufacturing footwear objects. For example, the sole structure can be made of any suitable material, including but not limited to: elastomers, siloxanes, natural rubber, other synthetic rubbers, aluminum, steel, natural leather, synthetic leather, foam, or plastic. Additionally, the upper can be made of any suitable material, including but not limited to: natural leather, synthetic leather, fabrics (including woven and nonwoven fabrics), and any other materials known in the art for constructing uppers. Moreover, the connecting members can be made of any material having the properties discussed above. In some cases, the connecting members can be made of a material configured to be substantially flexible. In other cases, the connecting members can be made of a material configured to compress and provide vibration absorption. In exemplary embodiments, the connecting members can be made of any suitable elastic material.

[0094] As discussed previously, the length of the connecting member 200 is variable. By changing the length of the connecting member 200, different parts of the upper 102 and the sole structure 110 can be connected in various ways. In particular, the upper 102 and the sole structure 110 can be partially connected at those parts that are connected together by the connecting member 200, and fully connected at other locations.

[0095] Figures 10 to 12 Alternative embodiments of footwear items with connecting members of different lengths and positions are shown. (Refer to...) Figures 10 to 12 Each footwear item may include the upper 102 and sole structure 110 discussed with respect to footwear item 100. Additionally, similar reference numerals are used to identify substantially similar components previously discussed with respect to footwear item 100. Furthermore, the connecting members discussed in these figures may have substantially similar properties to connecting member 200, and may differ primarily in length and position.

[0096] Now refer to Figure 10 Footwear component 1600, referred to herein simply as component 1600, includes a connecting member 1620, which is a full-length connecting member. Specifically, the connecting member 1620 extends substantially through the entire forefoot portion 10, midfoot portion 12, and heel portion 14. In some cases, the connecting member 1620 may not extend into the foremost portion of the forefoot portion 10. Similarly, in some cases, the connecting member 1620 may not extend into the rearmost portion of the heel portion 14. However, in other cases, the connecting member 1620 may extend throughout the entire length of component 1600, such that portions without the upper 102 and sole structure 110 are fully connected. Using this arrangement, substantially most of component 1600 can be partially separated to provide enhanced fit and stability throughout component 1600.

[0097] Now refer to Figure 11 Footwear item 1700, simply referred to herein as item 1700, includes a connecting member 1720. In this case, the connecting member 1720 extends further into the forefoot portion 10 than the connecting member 1620 of the previous embodiment. In other words, the connecting member 1720 is slightly longer in the front portion of item 1700. In this case, the connecting member 1720 may be spaced apart from the front edge 1750 of item 1700 by a length L1. In different embodiments, the value of the length L1 may vary. In some cases, the length L1 may have a value in the range of approximately 0.1 to 2 inches. In an exemplary embodiment, the length L1 may have a value of approximately 1 inch. This arrangement may provide additional separation in the forefoot portion 10 to improve the fit of item 1700 at the forefoot portion 10.

[0098] Now refer to Figure 12 The footwear component 1800 includes a connecting member 1820. In this case, the connecting member 1820 is primarily arranged in the heel portion 14 of the component 1800. Some portions of the connecting member 1820 also extend into the midfoot portion 12 or arch of the component 1800. This arrangement provides enhanced separation at the heel portion 14. Using this arrangement, the component 1800 provides enhanced fit to the heel of the foot and assists in stability at the heel portion 14.

[0099] The component may include a construction used only on the inside or outside of the component to separate the upper and sole structures. In some cases, the connecting component may be configured to separate the component on the outside. In other cases, the connecting component may be configured to separate the component on the inside.

[0100] Figures 13 to 18 This is intended to illustrate an embodiment of an object that separates only on the inside. (Refer to...) Figures 13 to 14Footwear item 1800, referred to herein as item 1800, is provided with an upper 102 and a sole structure 110 in a manner similar to that of item 100. Item 1800 may also include a connecting member 1900.

[0101] The connecting member 1900 may be generally arranged between the upper 102 and the sole structure 110, and can be used to connect portions of the upper 102 to portions of the sole structure 110. In particular, the current embodiment shows the connecting member 1900 generally arranged between the upper 102 and the sole structure 110 at the midfoot portion 12 of the object 1800, some portions of the forefoot portion 10, and the heel portion 14.

[0102] In some embodiments, the connecting member 1900 may further include a layered structure. In some cases, the connecting member 1900 may include two layers. In other cases, the connecting member 1900 may include more than two layers. In one embodiment, the connecting member 1900 may include an upper layer 1902 and a lower layer 1904.

[0103] Typically, the geometry of the upper layer 1902 and the lower layer 1904 can be varied. In some cases, the upper layer 1902 and the lower layer 1904 may have substantially planar geometry, such that the thickness of each layer is substantially less than the associated length and width of each layer. Additionally, in some cases, the upper outer perimeter 1910 of the upper layer 1902 and the lower outer perimeter 1912 of the lower layer 1904 may be shaped in a manner corresponding to the upper 102 and the sole structure 110.

[0104] The upper layer 1902 and the lower layer 1904 may be joined at the central attachment portion 1920. In particular, the central attachment portion 1920 is a substantially narrow portion that extends longitudinally through the connecting member 1900. In addition, the upper layer 1902 and the lower layer 1904 may be joined at the outer portion 1905 of the connecting member 1900.

[0105] The upper layer 1902 and the lower layer 1904 can be attached using any method known in the art. In some cases, the upper layer 1902 can be attached to the lower layer 1904 by stitching. In other cases, the upper layer 1902 can be attached to the lower layer 1904 using some type of adhesive. It should be understood that the method of attaching the upper layer 1902 to the lower layer 1904 can be selected based on the material properties of the upper layer 1902 and the lower layer 1904 and the desired structural performance for the connecting member 1900. In an exemplary embodiment, the upper layer 1902 can be attached to the lower layer 1904 using stitching 1922. Moreover, in some cases, the upper layer 1902 and the lower layer 1904 can be attached using adhesive in some type of area between the central attachment portion 1920 and the outer portion 1905. In other cases, the upper layer 1902 and the lower layer 1904 can be left unattached in the area between the central attachment portion 1920 and the outer portion 1905.

[0106] The connecting member 1900 may include one or more separation portions. In the current embodiment, the connecting member 1900 includes a separation portion 1930. The separation portion 1930 extends generally from the central attachment portion 1920 to the inner side 18 of the connecting member 1900. Moreover, the first separation portion 1930 includes a free portion 1942 of the upper layer 1902 and a free portion 1944 of the lower layer 1904. With this arrangement, the free portion 1942 of the upper layer 1902 can be configured to move substantially independently of the free portion 1944 of the lower layer 1904. In contrast to the previously discussed embodiments, the connecting member 1900 is not separated on the outer side 16. This arrangement provides separation between the upper 102 and the sole structure 110 on the inner side 18 and prevents separation between the upper 102 and the sole structure 110 on the outer side 16.

[0107] like Figure 15 As shown, when the upper 102 is angled outwards 16, the separation portion 1930 can be opened. Specifically, the free portions 1942 of the upper layer 1902 and 1944 of the lower layer 1904 separate to allow the lower outer periphery 316 of the upper 102 and the upper outer periphery 604 of the sole structure 110 to move away from each other on the inner side 18. This configuration allows the upper 102 to roll outwards 16. Therefore, the force is absorbed by the connecting member 1900. Moreover, the upper 102 and the sole structure 110 are allowed to separate partially to improve stability for the user.

[0108] However, as Figure 16 As shown, when the upper 102 is angled towards the inward side 18, no separation occurs on the outward side 18. Instead, the lower outer periphery 316 of the upper 102 and the upper outer periphery 604 of the sole structure 110 are fully connected at the outward side 18 because the upper layer 1902 and the lower layer 1904 are connected at the outward side 18. Therefore, in some cases, the object 1800 behaves similarly to a conventional type of shoe that is fully connected when rolling inward.

[0109] Figure 17 and 18 An alternative embodiment of the method of separating the upper on one side is shown. (Refer to...) Figure 17 and 18 The footwear item 2000 includes an upper 102 and a sole structure 110 in a manner similar to the previous embodiments. The footwear item 2000 also provides a connecting member 2050 disposed on the inner side 18 of the item 2000.

[0110] In this embodiment, the connecting member 2050 is configured as a single layer of material, which is folded in half to provide a separation portion 2050. The separation portion 2050 includes a first free portion 2062 and a second free portion 2064 respectively connected to the upper 102 and the sole structure 110. Moreover, in this current embodiment, the upper 102 and the sole structure 110 can be directly attached to each other on the outer side 16 of the object 2000. In particular, the lower surface 304 of the upper 102 and the upper surface 308 of the sole structure 110 are directly connected between the middle portion 2010 and the outer side 16 of the object 2000.

[0111] Using this arrangement, the upper 102 and the sole structure 110 can be partially separated at the inner side 18. This allows the width of the object 2000 to be partially adjusted on the inner side 18. Moreover, this enhances stability on the inner side 18.

[0112] While the current embodiment illustrates partial separation on the inside of the footwear, in other embodiments, the connecting member may be configured to provide partial separation on the outside of the object. For example, in another embodiment, the connecting member 2050 may be used on the outside 16 of the object 2000 to provide partial separation on the outside 16 rather than the inside 18.

[0113] Footwear items with connecting members may include constructions for covering the separated portion between the upper and sole. In some cases, the item may include one or more covering portions that cover openings that may form between the upper and sole structures during use. This arrangement helps prevent debris from entering the area between the partially separated upper and sole structures.

[0114] Reference Figure 19 and 20 Footwear item 2100, hereinafter referred to as item 2100, includes an upper 102 and a sole structure 110. Additionally, footwear item 2100 also includes a connecting member 200. As discussed earlier, the connecting member 200 provides partial separation between the upper 102 and the sole structure 110.

[0115] The object 2100 may also include one or more covering portions. In the current embodiment, the object 2100 may include a first covering portion 2120 and a second covering portion 2122, which are respectively disposed on the outer side 16 and inner side 18 of the object 2100. The first covering portion 2120 is generally disposed above the outer side 16 of the upper 102. Moreover, the first covering portion 2120 extends through the midfoot portion 12 and portions of the heel portion 14 and forefoot portion 10 of the object 2100. In an exemplary embodiment, the length of the first covering portion 2120 may be substantially similar to the length of the connecting member 200. Moreover, the covering portion 2120 may be substantially aligned longitudinally with the connecting member 200. In a similar manner, the second covering portion 2122 may be disposed on the inner side 18 of the upper 102. In addition, the second covering portion 2122 may have a length substantially similar to that of the connecting member 200. Moreover, the second covering portion 2122 may be substantially aligned longitudinally with the connecting member 200.

[0116] A first cover portion 2120 may extend from the outer lacing edge 2130 to the sole structure 110. In some cases, the lower edge 2140 of the first cover portion 2120 may be attached to the upper outer periphery 604 of the sole structure 110. In the current embodiment, the lower edge 2140 of the first cover portion 2120 may be attached between the upper surface 308 of the sole structure 110 and the first free portion 244 of the lower layer 204. Similarly, a second cover portion 2122 may extend from the inner lacing edge 2132 to the sole structure 110. In some cases, the lower edge 2142 of the second cover portion 2122 may be attached to the upper outer periphery 604 of the sole structure 110. In the current embodiment, the lower edge 2142 of the second cover portion 2122 may be attached between the upper surface 308 of the sole structure 110 and the second free portion 248 of the lower layer 204.

[0117] With this arrangement, the first cover portion 2120 can cover the first opening 2160, which is associated with the first separation portion 230. Similarly, the second cover portion 2122 can cover the second opening 2162, which is associated with the second separation portion 232. This configuration helps prevent debris from entering the first opening 2160 and the second opening 2162 due to the separation of the upper 102 and the sole structure 110 during use of the item 2100.

[0118] Reference Figure 21When the upper 102 rolls inwards towards the inside 18, the first opening 2160 can open. However, in this case, the first cover portion 2120 helps prevent any debris from entering the first opening 2160. Similarly, when the upper 102 rolls outwards towards the outside 16, the second cover portion 2122 helps prevent any debris from entering the second opening 2162.

[0119] Typically, the overlays can be made of any material with any material properties. Examples of different materials that can be used include, but are not limited to: natural leather, synthetic leather, natural fibers, synthetic fibers, composite materials, and any other materials. In some cases, one or more overlays may contain a substantially elastic material. By using a substantially elastic material, the overlays can adapt to the sides of the upper during use and can expand and contract when the upper is angled relative to the sole components.

[0120] In the current embodiment, the first covering portion 2120 and the second covering portion 2122 may include a substantially elastic mesh. Using a mesh material enhances the flexibility of the first covering portion 2120 and the second covering portion 2122. Figure 21 As shown, when the upper 102 is tilted, the first covering portion 2120 can be tightened, while the second covering portion 2122 can be loosened. Furthermore, the mesh material can be a breathable mesh that allows airflow through the first covering portion 2120 and the second covering portion 2122.

[0121] In some embodiments, one or more covering portions may be integrally formed with the connecting member. Now refer to Figure 22 The diagram shows a cross-sectional view of an alternative embodiment of the object. In this case, the object 2200 includes an upper 102 and a sole structure 110. Furthermore, the object 2200 includes a connecting member 2250. The connecting member 2250 includes an upper layer 2252 and a lower layer 2254. The connecting member 2250 also includes a first covering portion 2272 and a second covering portion 2274 integrally formed with the connecting member 2250. Specifically, the first covering portion 2272 is integrally formed with a first free portion 2262 of the lower layer 2254, while the second covering portion 2274 is integrally formed with a second free portion 2264 of the lower layer 2254. In other words, the connecting member 2250 serves to partially separate the upper 102 and the sole structure 110, and also provides coverage for the first opening 2282 and the second opening 2284.

[0122] Figures 23 to 25An exemplary embodiment of footwear article 1000 is shown. Footwear article 1000, simply referred to herein as article 1000, is substantially similar in many respects to article 100 previously described, including a forefoot portion 10, a midfoot portion 12, a heel portion 14, and arrangements of an outer side 16 and an inner side 18. Additionally, shoe 1000 includes an upper 102, a sole structure 110, and a connecting member 200, substantially similar to those described in the earlier embodiments. Reference numerals from the first embodiment are similarly used in this embodiment to describe the same features.

[0123] In some embodiments, footwear 1000 may include a fastening system configured to tighten the upper 102. Typically, footwear 1000 may be associated with any type of fastening system, including but not limited to: shoelaces, straps, zippers, hook-and-loop fasteners, and other types of fastening systems. In an exemplary embodiment, footwear 1000 includes a lacing system comprising a lacing area 1250 and shoelaces 1252. Shoelaces 1252 can be used to tighten the lacing area 1250 to bring together the outer lateral 16 and inner lateral 18 of the upper 102.

[0124] The object may include features to enhance the shoe upper's ability to adapt to the width of the foot. In embodiments that include a connecting member, the object may include a band for providing tension to a portion of the connecting member. In an exemplary embodiment, the object may include a pair of bands for applying tension to the upper layer of the connecting member.

[0125] Reference Figures 23 to 25 The object 1000 may include a first strap 1202 and a second strap 1204. In some cases, the first strap 1202 may extend across the outer side 16 of the upper 102 at the midfoot portion 12. In one embodiment, the first strap 1202 may include a first end 1210 attached to a first free portion 242 of the upper 202. Furthermore, the first strap 1202 may include a second end 1212 associated with the outer side 16 of the lacing region 1250. In some cases, the second end 1212 may include a lacing hole 1214 for receiving the shoelace 1252. Similarly, the second strap 1204 may include a first end 1220 attached to a second free portion 246 of the upper 202. Furthermore, the second strap 1204 may include a second end 1222 associated with the inner side 18 of the lacing region 1250. In some cases, the second end 1222 may include a lacing hole (not shown) for receiving the shoelace 1252. With this arrangement, the first strap 1202 and the second strap 1204 can provide tension to the first free portion 242 and the second free portion 246 of the upper layer 202, respectively, when the shoelace 1252 is adjusted.

[0126] When the shoelaces 1252 are tightened, the first strap 1202 and the second strap 1204 can be used to pull the first free portion 242 and the second free portion 246 of the upper layer 202 away from the first free portion 244 and the second free portion 248 of the lower layer 204. In other words, the first strap 1202 and the second strap 1204 can substantially open the first separation portion 230 and the second separation portion 232 when the first strap 1202 and the second strap 1204 pull the sidewall of the upper 102 inward around the foot. This configuration generally allows the upper 102 to be tightened around the foot to enhance fit and comfort.

[0127] like Figure 24 As shown, in the relaxed position, the upper 102 can be associated with the width W7. Specifically, this width can generally correspond to the relaxed position for the first strap 1202 and the second strap 1204. Furthermore, in this relaxed position, the lower outer periphery 316 of the upper 102 is generally positioned on the upper outer periphery 604 of the sole structure 110. However, when the first strap 1202 and the second strap 1204 are tightened, as... Figure 25 As shown, the width of the upper 102 can be substantially reduced to a width W8. In this case, the first strap 1202 and the second strap 1204 apply tension to the upper layer 202, causing the first free portion 242 and the second free portion 246 to be pulled upwards and inwards. This further causes the lower outer periphery 316 attached to the first free portion 242 and the second free portion 244 to contract inwards. With this arrangement, the width of the upper 102 can be adjusted by applying varying degrees of tension to the first strap 1202 and the second strap 1204 using the shoelaces 1252.

[0128] Footwear item 1000 can be manufactured using any known materials. The materials used for the upper 102, sole structure 110, and connecting members 200 have already been discussed above. Additionally, the straps used with the footwear item can be made of any suitable material, including textiles, fabrics, leather, rubber, elastomers, and any other materials.

[0129] The number of bands can vary in different embodiments. For example, in Figure 26 In another embodiment shown, the footwear item 1000 may include a strap 1099 disposed on the outer side 16. In another embodiment, a strap may be disposed on the inner side 18. In other embodiments, the item may include more than two straps.

[0130] The object may include a number of different materials or components used to manufacture the object. In some embodiments, the object may include one or more straps integrally formed with a connecting member. In an exemplary embodiment, the straps for the object may be integrally formed with the upper layer of the connecting member.

[0131] Reference Figure 27and 28 The footwear component 2300, referred to herein simply as component 2300, includes an upper 102 and a sole structure 110. Component 2300 also includes a connecting member 2350 that separates the upper 102 relative to the sole structure 110. The connecting member 2350 includes an upper layer 2352 attached to the upper 102 and a lower layer 2354 attached to the sole structure 110. Furthermore, component 2300 includes a first strap 2320 and a second strap 2322 extending between the upper 102 and the sole structure 110.

[0132] In the current embodiment, the first strap 2320 is integrally formed with the first free portion 2362 of the upper layer 2352 of the connecting member 2350. Similarly, the second strap 2322 is integrally formed with the second free portion 2364 of the upper layer 2352 of the connecting member 2350. With this arrangement, when the first strap 2320 and the second strap 2322 are tightened around the foot, the lower outer periphery 316 of the upper 102 is tightened against the bottom of the foot because the first free portion 2362 and the second free portion 2364 are pulled upward. This arrangement can provide enhanced fit to the foot in the area of ​​the foot corresponding to the connecting member 2350. Moreover, this configuration reduces the need for separate components forming the straps, since the straps are formed continuously from the portion of the connecting member 2350.

[0133] Reference Figure 29 and 30 The straps can be used in combination with the covering portion. In this case, the footwear item 2400 is provided with an upper 102 and a sole structure 110. The footwear item 2400, referred to herein simply as item 2400, also provides a connecting member 200. Item 2400 also includes a first strap 2420 and a second strap 2422, which are attached to the upper layer 202 of the connecting member 200.

[0134] In some embodiments, the first strap 2420 and the second strap 2422 may be covered. In some cases, the first strap 2420 and the second strap 2422 may be partially covered. In other cases, the first strap 2420 and the second strap 2422 may be completely covered. In an exemplary embodiment, the first strap 2420 and the second strap 2422 may be completely covered using the first covering portion 2460 and the second covering portion 2462. In this case, the first covering portion 2460 and the second covering portion 2462 may be located between the lower layer 204 of the connecting member 200 and the sole structure 110, similar to the previous arrangement. Figure 20 The arrangement shown is attached to the object 2400. Using this arrangement, the first cover portion 2460 can be configured to prevent debris from entering the first opening 2480 of the first separation portion 230. Similarly, the second cover portion 2462 can be configured to prevent debris from entering the second opening 2482 of the second separation portion 232.

[0135] Although the first strip 2420 and the second strip 2422 are separate components from the connecting member in the current embodiment, in other embodiments, the first strip 2420 and the second strip 2422 may be integrally formed with the connecting member 200. In some cases, the first strip 2420 and the second strip 2422 may be formed as a continuous extension of the upper layer 202 of the connecting member 200, such as... Figure 27 and 28 As shown in the previous embodiments. Furthermore, although the first covering portion 2460 and the second covering portion 2462 are components separate from the connecting member 200 in the current embodiment, in other embodiments, the first covering portion 2460 and the second covering portion 2462 may be integrally formed with the connecting member 200. In some cases, the first covering portion 2460 and the second covering portion 2462 may be formed as a continuous extension of the lower layer 204 of the connecting member 200, such as... Figure 22 As shown in the previous embodiments.

[0136] In some embodiments, one or more straps may be formed continuously with a portion of the upper. In some cases, the straps may be formed from a wing-like portion of the upper. In one embodiment, the straps may be formed by cutting one or more grooves in a portion of the upper.

[0137] Figures 31 to 33 An exemplary embodiment of a footwear article 2500 is shown. The article 2500 may include an upper 2502, a sole structure 2510, and a connecting member 2600 for partially connecting the upper 2502 to the sole structure 2510. In this embodiment, the upper 2502 may have substantially similar properties to the upper 102 discussed in the previous embodiment. Similarly, the sole structure 2510 may have substantially similar properties to the sole structure 110 discussed in the previous embodiment. Moreover, the connecting member 2600 may be substantially similar to the connecting member 200 of the previous embodiment.

[0138] Reference Figures 31 to 33 The upper 2502 may include one or more integral straps. In this embodiment, the upper 2502 includes a first integral strap 2520 disposed on the outer side 16 of the upper 2502. Additionally, the upper 2502 may include a second integral strap 2522 disposed on the inner side 18 of the upper 2502, and... Figure 33 The first integral strip 2520 is shown in cross-section. For clarity, the following detailed description discusses the first integral strip 2520. However, it should be understood that the second integral strip 2522 may be substantially similar to the first integral strip 2520.

[0139] The first integrated band 2520 may be a wing-like portion of the upper 2502, extending from the lower outer periphery 2516 of the upper 2502. In some cases, the first integrated band 2520 may be associated with a first groove 2530 and a second groove 2532, which respectively separate a first edge 2524 and a second edge 2526 of the first integrated band 2520 from the upper 2502. In other words, this configuration allows the first integrated band 2520, which is continuously formed with the upper 2502, to move substantially independently of the adjacent portion of the upper 2502. In particular, with this arrangement, the first integrated band 2520 can be tightened around the foot slightly independently of the rest of the upper 2402.

[0140] In the current embodiment, a first integrated strap 2520 extends from the lower outer periphery 2516 of the upper 2502 to the outer lacing edge 2518 of the upper 2502. Furthermore, the first integrated strap 2520 includes lacing holes 2528 configured to receive shoelaces 2503. When the shoelaces 2503 are tightened, the first integrated strap 2520 is pulled more tightly against the outside of the foot. Similarly, a second integrated strap 2522 may also be configured to have one or more lacing holes so that the second integrated strap 2522 can tighten against the foot when the shoelaces 2503 are tightened.

[0141] When the first integrated strap 2520 and the second integrated strap 2522 are tightened, they can apply a tension force to the upper layer 2602 of the connecting member 2600. This allows the upper layer 2602 to tighten around the base of the foot for better adjustment of the upper 2502 with respect to the width of the foot. With this arrangement, the first integrated strap 2520 and the second integrated strap 2522 can be used as discussed above and Figure 24 and 25 The width of the upper 2502 is adjusted in a similar manner to the embodiment shown.

[0142] In some embodiments, the first cover portion 2570 and the second cover portion 2572 may also be used with the object 2500. In this case, the first cover portion 2570 extends from the lower outer periphery 2517 of the sole structure 2510 to the outer lacing edge 2518 of the upper 2502. This provides coverage for the first opening 2590 associated with the connecting member 2600 on the outer side 16. In some cases, the first cover portion 2570 may also help prevent debris from entering the upper 2502 through the first groove 2530 and the second groove 2532. Similarly, the second cover portion 2572 extends from the upper outer periphery 2517 of the sole structure 2510 to the inner lacing edge 2519 of the upper 2502. This provides coverage for the second opening 2592 associated with the connecting member 2600 on the inner side 18 and any associated grooves adjacent to the second integral strap 2522. However, it should be understood that in other embodiments, the cover portions may not be used.

[0143] The object may include a construction for reinforcing an integral strap associated with the upper. In embodiments that include a connecting member, a portion of the connecting member may extend to reinforce the integral strap. In one exemplary embodiment, an upper layer of the connecting member may extend to reinforce the integral strap.

[0144] Figure 34 and 35 Another embodiment of a footwear item is shown, configured to be partially separated between the upper and sole structure. (See reference...) Figure 34 and 35 Footwear item 3400, referred to herein simply as item 3400, includes an upper 2502 and a sole structure 2510. The upper 2502 includes a first integrated strap 2520 and a second integrated strap 2522, which have been previously discussed in earlier embodiments. Specifically, the first integrated strap 2520 and the second integrated strap 2522 form a wing-like portion of the upper 2520, which can move substantially independently of adjacent portions of the upper 2502. With this arrangement, the first integrated strap 2520 and the second integrated strap 2522 can be tightened around the foot during use.

[0145] Article 3400 includes a connecting member 2700, which is used to partially separate the upper 2502 and the sole structure 2510. The connecting member 2700 may generally be arranged between the upper 2502 and the sole structure 2510, and can be used to connect portions of the upper 2502 to portions of the sole structure 2510. Specifically, the current embodiment shows the connecting member 2700 generally arranged between the upper 2502 and the sole structure 2510 at the midfoot portion 12, some portions of the forefoot portion 10, and the heel portion 14 of article 3400.

[0146] In some embodiments, the connecting member 2700 may further include a layered structure. In some cases, the connecting member 2700 may include two layers. In other cases, the connecting member 2700 may include more than two layers. In one embodiment, the connecting member 2700 may include an upper layer 2702 and a lower layer 2704.

[0147] The upper layer 2702 and the lower layer 2704 may be joined at a central attachment portion 2720. Specifically, the central attachment portion 2720 is a substantially narrow portion extending longitudinally through the connecting member 2700. The upper layer 2702 and the lower layer 2704 may be attached using any method known in the art. In some cases, the upper layer 2702 may be attached to the lower layer 2704 by stitching. In other cases, the upper layer 2702 may be attached to the lower layer 2704 using some type of adhesive. It should be understood that the method of attaching the upper layer 2702 to the lower layer 2704 may be selected based on the material properties of the upper layer 2702 and the lower layer 2704 and the desired structural performance for the connecting member 2700. In an exemplary embodiment, the upper layer 2702 may be attached to the lower layer 2704 using stitching 2722.

[0148] The connecting member 2700 may include one or more detachable portions. In the current embodiment, the connecting member 2700 includes a first detachable portion 2730 and a second detachable portion 2732. The first detachable portion 2730 extends generally laterally from the central attachment portion 2720 to the outer side 16 of the connecting member 2700. Furthermore, the first detachable portion 2730 includes a first free portion 2742 of the upper layer 2702 and a first free portion 2744 of the lower layer 2704. The second detachable portion 2732 extends generally laterally from the central attachment portion 2720 to the inner side 18 of the connecting member 2700. Furthermore, the second detachable portion 2732 includes a second free portion 2746 of the upper layer 2702 and a second free portion 2748 of the lower layer 2704. With this arrangement, the first free portion 2742 of the upper layer 2702 can be configured to move substantially independently of the first free portion 2744 of the lower layer 2704. Similarly, the second free portion 2746 of the upper layer 2702 can be configured to move substantially independently of the second free portion 2748 of the lower layer 2704.

[0149] Typically, the geometry of the upper layer 2702 and the lower layer 2704 can be varied. In some cases, the upper layer 2702 and the lower layer 2704 may have substantially planar geometry, such that the thickness of each layer is substantially less than the associated length and width of each layer. Additionally, in some cases, the upper outer perimeter 2710 of the upper layer 2702 and the lower outer perimeter 2712 of the lower layer 2704 may be shaped in a manner corresponding to the upper 2502 and the sole structure 2510.

[0150] In some embodiments, the geometry of the upper layer 2702 may differ from that of the lower layer 2704. In some cases, the upper layer 2702 may include one or more extensions. In the present embodiment, the upper layer 2702 includes a first extension 2780 that extends continuously from the first free portion 2742. The first extension 2780 may be generally shaped similarly to the first integral strip 2520 and may be configured to wrap around and reinforce the first integral strip 2520. The upper layer 2702 may also include a second extension 2782 that extends continuously from the second free portion 2746. The second extension 2782 may be generally shaped similarly to the second integral strip 2522 and may be configured to wrap around and reinforce the second integral strip 2522.

[0151] In some embodiments, the first extension portion 2780 and the second extension portion 2782 may be provided with lacing holes 2790 configured to engage shoelaces 2503. With this arrangement, when the shoelaces 2503 are tightened, the first extension portion 2780 and the first integrated strap 2520 can be tightened close to the foot. Similarly, when the shoelaces 2503 are tightened, the second extension portion 2782 and the second integrated strap 2522 can be tightened close to the foot. This arrangement helps to improve support for the first integrated strap 2520 and the second integrated strap 2522. Moreover, using this configuration, the width of the upper 2502 at the midfoot portion 12 can be adjusted by the tension in the upper layer 2702 of the shoelace control member 2700 via the shoelaces 2503.

[0152] The object may include a construction for reinforcing one or more portions of the connecting member. In some cases, the connecting member may include a line that provides structural support. Objects having lines configured to provide structural support have previously been disclosed in U.S. Patent Application Publication No. 2007 / 0271822, issued to Meschter, the entire contents of which are incorporated herein by reference. Additionally, U.S. Patent Application Publication No. 2007 / 0271823, also issued to Meschter, is incorporated herein by reference. Both references will be referred to as examples of line structural elements throughout the following sections of this Detailed Description.

[0153] Now refer to Figures 36 to 38In another embodiment, the connecting member 2700 may be associated with a plurality of wires 2800, which are simply referred to herein as wires 2800. In some embodiments, the wires 2800 may be arranged on some type of base layer. In some cases, the wires 2800 may be arranged on the surface of the upper layer 2702 of the connecting member 2700. In some cases, the wires 2800 may be arranged on the surface of the lower layer 2704. In still other cases, the wires 2800 may be arranged on both the upper layer 2702 and the lower layer 2704. In some cases, the wires 2800 may be arranged substantially on the surface of the upper layer 2702. Moreover, the plurality of wires 2800 may extend from the end 2792 of the first extension 2780 to the end 2794 of the second extension 2782.

[0154] In some cases, portions of the wire 2800 may be parallel to the surface of the upper layer 2702. In other words, portions of the wire 2800 may be exposed on the surface of the upper layer 2702, rather than embedded in the upper layer 2702. In other cases, portions of the wire 2800 may extend through the upper layer 2702. In the portions where the wire 2800 extends through the upper layer 2702, the wire 2800 may be directly bonded to or otherwise secured to the upper layer 2702. In other cases, portions of the wire 2800 may be disposed adjacent to the upper layer 2702. In the portions where the wire 2800 is disposed adjacent to the upper layer 2702, the wire 2800 may not be secured to the upper layer 2702, or it may be bonded using a connecting layer or other securing elements that adhesively, securely, or otherwise bond portions of the wire 2800 to the upper layer 2702.

[0155] In some embodiments, in order to form structural elements in the upper layer 2702, multiple lines 2800 or portions of individual lines 2800 may be grouped into one of multiple line groups. However, in other embodiments, the lines 2800 may not be divided into different line groups.

[0156] In some embodiments, the line 2800 may begin and terminate at one or more lacing holes. For example, in the current embodiment, the line 2800 is connected to the lacing hole 2790. In some cases, the line 2800 may be more compactly packed together in the area adjacent to the lacing hole 2790.

[0157] In different embodiments, the lines or groups of lines can be arranged in different ways. For example, in some cases, each line in a group of lines can extend substantially straight from a first end of the group to a second end. However, in other cases, the lines can have multiple sections that are angled relative to each other. In still other cases, the lines can be arranged in a curved shape.

[0158] The process of applying line 2800 to the upper layer 2702 can be implemented using any method known in the art. In particular, the order of application of different lines from different line groups can vary from one embodiment to another. An example of the process of applying lines to the upper of a footwear item is discussed in the case of a line structural element. It should be understood that similar methods can be used to apply lines to a base layer for fixation.

[0159] In different embodiments, each thread of the thread 2800 may be secured to the upper layer 2702 in different ways. In one embodiment, the ends of the thread 2800 may be secured to the upper layer 2702 using a lock stitch. Alternatively, the middle portions of the thread 2800 may be attached to the upper layer 2702 using a connecting layer that adhesively, secures, or otherwise binds portions of the thread 2800 to the upper layer 2702. However, in other embodiments, the thread 2800 may be embedded within the upper layer 2702, particularly in embodiments where the upper layer 2700 comprises a polymer layer.

[0160] During use of object 2500, the forces generated in object 3400 may tend to stretch portions of upper 2502 and upper layer 2702, the latter partially wrapping around upper 2502. Each of the threads 2800 is configured to form a structural element in connecting member 2700. These structural elements can help resist stretching in various directions and reinforce locations of force concentration. In particular, in some embodiments, the threads 2800 substantially inhibit stretching of upper layer 2702 along a direction corresponding to the longitudinal axis of the thread. In the current embodiment, this direction generally corresponds to the lateral direction across connecting member 2700, which helps maintain tension around portions of upper 2502 of first extension 2780 and second extension 2782.

[0161] Figure 37 and 38 An isometric view and a cross-sectional view of one embodiment of footwear 3400 are shown. For clarity, the upper 2502 and the sole structure 2510 are... Figure 37 It is shown in dashed lines. For example... Figure 37 and 38As shown, the current design provides a threading method that essentially surrounds the upper 2502. Specifically, thread 2800 is positioned on the outer side 16 and inner side 18 of the upper 2502. Additionally, thread 2800 is positioned below the lower portion 2525 of the upper 2502. Moreover, thread 2800 extends substantially continuously from the outer lacing edge 2518 to the inner lacing edge 2519 by extending around the outer side 16 below the lower portion 2525 and around the inner side 18. With this arrangement, the foot inserted into the upper is supported by thread 2800 on almost all sides, except for the instep area corresponding to the opening in the lacing region. Specifically, the bottom of the foot is supported below by the portion of thread 2800 that crosses the lower layer 2704 and extends below the lower portion 2525.

[0162] In some embodiments, the thread 2800 may provide varying amounts of coverage along the direction surrounding the upper 2502. In some cases, the thread 2800 may provide substantially continuous coverage of approximately 180 degrees or more around the upper 2502. In other cases, the thread 2800 may provide substantially continuous coverage of approximately 270 degrees or more around the upper 2502. In still other cases, the thread 2800 may provide substantially continuous coverage of approximately 330 degrees or more around the upper 2502. In yet another few cases, the thread 2800 may provide substantially continuous coverage of approximately 350 degrees or more around the upper 2502. In embodiments without a lacing area, or in embodiments where the thread 2800 extends over a lacing area, the thread 2800 may provide substantially continuous coverage of approximately 360 degrees. By occupying a larger portion of the upper, the thread 2800 may provide a greater amount of support to the foot.

[0163] While the current embodiment includes a thread applied to the upper layer of the connecting member, in other embodiments, the thread may be applied to any other base layer of the object. In some cases, the thread may be applied to the lower layer of the connecting member. In still other cases, the thread may be applied to both the upper and lower layers of the connecting member. In yet another case, the thread may be applied directly to a portion of the upper.

[0164] The connecting member may be provided with multiple extensions on each side. In some cases, the connecting member may include two or more extensions on each side. In an exemplary embodiment, the connecting member may include three extensions on each side.

[0165] Reference Figure 39The connecting member 2900 includes a first extension 2981, a second extension 2982, and a third extension 2983 disposed on the outer side 16. Additionally, the connecting member 2900 includes a fourth extension 2984, a fifth extension 2985, and a sixth extension 2986 disposed on the inner side 18. Furthermore, each extension is continuously formed with the upper layer 2902 of the connecting member 2900.

[0166] In some cases, the connecting member 2900 may include multiple wires 3000 extending through a large portion of the upper layer 2902. In this case, the wires 3000 include a first group 3002, a second group 3004, and a third group 3006. The first group 3002 includes wires extending from a first extension 2981 to a fourth extension 2984. The second group 3004 includes wires extending from a second extension 2982 to a fifth extension 2985. Additionally, the third group 3006 includes wires extending from a third extension 2983 to a sixth extension 2986. This arrangement can provide increased structural support to the extensions of the connecting member 2900 and a large portion of the upper layer 2902.

[0167] Figure 40 An isometric view of an embodiment of a footwear item 3100 including a connecting member 2900 is shown. For clarity, the upper 2502 and the sole structure 2510 are shown in dashed lines in the current embodiment. Figure 41 An isometric view showing an exemplary embodiment of the footwear item 3100.

[0168] Reference Figure 40 and 41 Each extension portion can wrap around the outer side 16 or inner side 18 of the upper 2502. In this case, the first extension portion 2981, the second extension portion 2982, and the third extension portion 2983 can wrap around the outer side 16 of the upper 2502. In some cases, the second extension portion 2982 can overlap with the first integrated strap 2520. Moreover, each of the first extension portion 2981, the second extension portion 2982, and the third extension portion 2983 can be attached to the outer lacing edge 2518. In addition, the fourth extension portion 2984, the fifth extension portion 2985, and the sixth extension portion 2986 can wrap around the inner side 18 of the upper 2502. In some cases, the fifth extension portion 2985 can overlap with the second integrated strap 2522. Each of the fourth extension portion 2984, the fifth extension portion 2985, and the sixth extension portion 2986 can be attached to the inner lacing edge 2519. With this arrangement, the connecting member 2900 can provide enhanced support to the upper 2502 and allow the upper 2502 to partially separate from the sole structure 2510.

[0169] Figures 42 to 46Another embodiment of a connecting member for object 1300 is shown, object 1300 being referred to herein simply as object 1300. (Refer to...) Figure 42 The footwear object 1300 is substantially similar in many respects to the previously described object 100, including the forefoot portion 10, midfoot portion 12, heel portion 14, and the arrangement of the outer side 16 and the inner side 18. Additionally, the footwear object 1300 includes an upper 1300 and a sole structure 1302, which are substantially similar to those described in the earlier embodiments. Reference numerals from the first embodiment are similarly used in this embodiment to describe the same features.

[0170] In some embodiments, footwear item 1300 may include a fastening system configured to tighten the upper 1302. Typically, footwear item 1300 may be associated with any type of fastening system, including but not limited to: shoelaces, straps, zippers, hook and loop fasteners, and other types of fastening systems. In an exemplary embodiment, footwear item 1300 includes a lacing system comprising a lacing area 1350 and shoelaces 1352. Shoelaces 1352 can be used to tighten the lacing area 1350 to bring together the outer lateral 16 and inner lateral 18 of the upper 1302.

[0171] Reference Figure 42 and 43 The footwear item 1300 may include a connecting member 1400. The connecting member 1400 may be generally arranged between the upper 1302 and the sole structure 1310, and can be used to connect portions of the upper 1302 to portions of the sole structure 1310. Specifically, the current embodiment shows the connecting member 1400 generally arranged between the upper 1302 and the sole structure 1310 at the midfoot portion 12, some portions of the forefoot portion 10, and the heel portion 14 of the item 1300.

[0172] The connecting member 1400 may include an upper portion 1402 and a lower portion 1404. The upper portion 1402 may be associated with the upper 1302. The lower portion 1404 may be associated with the sole structure 1310. The connecting member 1400 may also include a first sidewall 1406 and a second sidewall 1408 extending between the upper portion 1402 and the lower portion 1404. Furthermore, the connecting member 1400 may include a first upper outer peripheral edge 1420 disposed between the upper portion 1402 and the first sidewall 1406; and a second upper outer peripheral edge 1422 disposed between the upper portion 1402 and the second sidewall 1408. The connecting member 1400 may also include a first lower outer peripheral edge 1424 disposed between the lower portion 1404 and the first sidewall 1406; and a second lower outer peripheral edge 1426 disposed between the lower portion 1404 and the second sidewall 1408.

[0173] In different embodiments, the geometry of the connecting member 1400 can be varied. In some embodiments, the connecting member 1400 may be substantially a single unit. Additionally, in some embodiments, the connecting member 1400 may have a generally tapered geometry. In some cases, the first sidewall 1406 and the second sidewall 1408 may taper from the midfoot portion 12 toward the forefoot portion 10 and the heel portion 14. In other words, the height of the first sidewall 1406 and the second sidewall 1408 may be greatest at the midfoot portion 12. Moreover, the upper outer periphery 1410 and the lower outer periphery 1412 of the connecting member 1400 may be shaped in a manner similar to the upper 1302 and the sole structure 1310. However, in other embodiments, each connecting member 1400 may have any type of geometry.

[0174] In different embodiments, the stiffness of the connecting member 1400 may vary. In some cases, the connecting member 1400 may be substantially rigid. In other cases, the connecting member 1400 may be substantially flexible. In still other cases, the connecting member 1400 may include substantially rigid portions and substantially flexible portions. In an exemplary embodiment, the connecting member 1400 may be partially compressed to provide impact absorption to the object 1300.

[0175] The connecting member 1400 may be attached to the upper 1302. In some cases, the upper portion 1402 may be attached to the upper 1302. In some embodiments, substantially all of the upper portion 1402 may be attached to the lower portion 1314 of the upper 1302. Moreover, in some embodiments, a first upper outer peripheral edge 1420 and a second upper outer peripheral edge 1422 may be attached to the lower outer periphery 1316 of the upper 1302.

[0176] The connecting member may include constructions for providing separation between the upper and the sole. In some cases, the connecting member may include constructions for selectively defining attachment areas between the connecting member and the sole structure. In an exemplary embodiment, the connecting member may include markings for identifying various possible attachment areas between the connecting member and the sole structure.

[0177] In the current embodiment, the lower portion 1404 of the connecting member 1400 may include a mark 1500. In some cases, the mark 1500 may include a line that can be used to select a predetermined attachment area between the connecting member 1400 and the mark 1500. In some cases, the mark 1500 may be a straight line. In other cases, the mark 1500 may be a curved and / or non-straight line.

[0178] Typically, the mark 1500 can be formed using various methods. In some cases, the mark 1500 can be formed using certain types of pigments. In other cases, the mark 1500 can be formed as a groove or engraved into the lower portion 1404. In still other cases, the mark 1500 can be associated with the lower portion 1404 in any other way.

[0179] Marker 1500 typically includes a pair of lines defining a central attachment area for attaching the connecting member 1400 to the sole mechanism 1310. For example, marker 1500 may include a first line 1501 and a second line 1502, respectively arranged closest to a first lower outer peripheral edge 1424 and a second lower outer peripheral edge 1426. Additionally, marker 1500 may include a third line 1503 and a fourth line 1504, arranged closest to the central portion 1403 of the connecting member 1400. Each pair of opposing lines defines a central attachment area. This refers to... Figure 44 and 45 The best example is shown.

[0180] Reference Figure 44 The lower portion 1404 of the connecting member 1400 has been attached to the sole structure 1310 using a first attachment area 1540. Specifically, in this case, the lower portion 1404 is attached to the sole structure 1310 only at the first attachment area 1540, the boundary of which is defined by a third line 1503 and a fourth line 1504. The first attachment area 1540 is a relatively narrow attachment area, which provides increased separation between the upper 1302 and the sole structure 1310 at the midfoot portion 12.

[0181] Since the third line 1503 and the fourth line 1504 are substantially complete, the width of the attachment region 1540 varies along the length of the connecting member 1400. For example, in the current embodiment, the attachment region 1540 has a width W21 at the middle leg portion 12 and a width W22 at the heel portion 14. In this case, the width W21 is substantially smaller than the width W22. In other words, the attachment region 1540 is larger at the heel portion 14 than at the middle leg portion 12. This arrangement can provide enhanced separation at the middle portion 12 compared to the heel portion 14. Moreover, as Figure 44 As shown, the upper 1302 and the sole structure 1310 are completely separated along the sole structure 1310 at the forefoot portion 10 because the connecting member 1400 does not extend through most of the forefoot portion 10.

[0182] Now refer to Figure 45In another embodiment, the connecting member 1400 may be attached to the sole structure 1310 using a second attachment region 1542. In this case, the second attachment region 1542 is substantially wider than the first attachment region 1540. Specifically, the second attachment region 1542 has a width W23 at the midfoot portion 12 and a width W24 at the heel portion 14. Widths W23 and W24 are wider than... Figure 44 The widths W21 and W22 associated with the first attachment region 1540 shown are wider. This configuration for connecting member 1400 can provide the object 1300 with a wider range of dimensions in the middle leg portion 12 and heel portion 14 than... Figure 44 The configuration shown represents a greater degree of separation.

[0183] Figure 46 and 47 A cross-sectional view of an embodiment of the object 1300 taken at the midfoot portion 12 is shown. In this case, the lower portion 1404 of the connecting member 1400 can be connected to the sole structure 1310 at the first attachment area 1560. With this arrangement, the upper 1302 and the outer and inner sides of the sole structure 1310 can be separated at the midfoot portion 12.

[0184] like Figure 46 As shown, the upper 1302 can be configured to have an initial width W25. In this position, the width W25 of the upper 1302 can be smaller than the width W26 of the sole structure 1310. In this case, the connecting member 1400 can be in a non-deformable state, with the first upper outer peripheral edge 1420 and the second upper outer peripheral edge 1422 generally arranged above the first lower outer peripheral edge 1424 and the second lower outer peripheral edge 1426, respectively.

[0185] Now refer to Figure 47 The upper 1302 can expand to a width W27 to accommodate a wider foot (not shown). To accommodate this wider width, the first upper outer peripheral edge 1420 and the second upper outer peripheral edge 1422 deform outward above the first lower outer peripheral edge 1424 and the second lower outer peripheral edge 1426, respectively. As already discussed, the first upper outer peripheral edge 1420 and the first lower outer peripheral edge 1424 are partially separated. Similarly, the second upper outer peripheral edge 1422 and the second lower outer peripheral edge 1426 are partially separated. In this extended position, the width W27 of the upper 1302 is substantially greater than the width W26 of the sole structure 1310. This arrangement allows the width of the upper 1302 to accommodate feet of varying widths in the area of ​​the object 1300 associated with the connecting member 1400.
