Description

[0001] This application is a divisional application of invention application No. 202110420400.8, filed on September 23, 2016.

[0002] Cross-reference to related applications

[0003] This application claims priority to U.S. Patent Application Serial No. 14 / 863,753, filed on September 24, 2015, the entire disclosure of which is incorporated herein by reference. Technical Field

[0004] This disclosure generally relates to footwear articles, and more specifically to fluid filling chambers for footwear articles and methods of manufacturing fluid filling chambers. Background Technology

[0005] This section provides background information relating to this disclosure, and such background information is not necessarily prior art.

[0006] Footwear typically includes a sole structure that provides a layer between the foot and the ground when wearing the footwear. The sole structure prevents the foot from contacting the ground and provides cushioning during use. The sole structure generally includes an outsole that contacts the ground and a midsole that supports, stabilizes, and cushions the foot. Polymer foam materials can be formed in the midsole to provide cushioning when the outsole impacts the ground, thereby minimizing the force felt by the foot.

[0007] While traditional midsole materials such as polymer foams offer a degree of comfort and stability, these foams are typically tailored to provide a specific type of cushioning and are often limited in this respect. For example, firmer foams offer a more responsive feel during use but are less effective at absorbing shock. Conversely, softer materials are less responsive but offer a greater degree of cushioning, making them better suited for applications where shock absorption is preferred over responsiveness. Therefore, providing a sole structure with more than one type of cushioning system allows footwear to offer both a responsive feel and shock absorption capabilities during use.

[0008] To balance responsiveness and cushioning, footwear manufacturers typically offer sole constructions with more than one type of cushioning. For example, the midsole may be formed from polymer foam material combined with rubber posts or resilient members. During use, the posts provide a responsive feel, while the polymer foam material provides cushioning. While rubber posts or other resilient members can be combined with polymer foam, other cushioning systems, such as fluid-filled bladders, can alternatively be used depending on the specific application.

[0009] Although the sole construction of conventional footwear products may include more than one type of cushioning system, these systems are typically separate and independent of each other. Therefore, these systems individually provide responsiveness and cushioning for the footwear product and only cooperate with each other when assembled into the sole construction. Summary of the Invention

[0010] This disclosure provides a sole structure for a footwear article having an upper, the sole structure including a fluid-filled chamber. The fluid-filled chamber includes: (i) a first barrier layer, (ii) a second barrier layer fixed to the first barrier layer to define an internal void between the first and second barrier layers, and (iii) a foam structure disposed within the internal void, the foam structure including a first recessed surface facing the upper and a second surface disposed on a side of the foam structure opposite to the first recessed surface.

[0069] Throughout the accompanying drawings, corresponding reference numerals indicate the corresponding parts. Detailed Implementation

[0070] Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough and will fully convey the scope of this disclosure to those skilled in the art. Specific details, such as those of particular components, apparatus, and methods, are set forth to provide a thorough understanding of the configurations of this disclosure. It will be apparent to those skilled in the art that specific details are not required, that the example configurations may be implemented in many different forms, and that the specific details and example configurations should not be construed as limiting the scope of this disclosure.

[0071] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. The terms “comprising,” “including,” “containing,” and “having” are inclusive and thus describe the presence of features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or illustrated, unless specifically stated as such. Additional or alternative steps may be employed.

[0072] When an element or layer is referred to as “on another element or layer,” “joined to another element or layer,” “connected to another element or layer,” “attached to another element or layer,” or “coupled to another element or layer,” it may be directly joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. In contrast, when an element is referred to as “directly on another element or layer,” “directly joined to another element or layer,” “directly connected to another element or layer,” “directly attached to another element or layer,” or “directly coupled to another element or layer,” there may be no intermediate elements or layers present. Other terms used to describe relationships between elements (e.g., “between” and “directly between,” “adjacent” and “directly adjacent,” etc.) should be understood in a similar manner. As used herein, the term “and / or” includes any and all combinations of one or more of the associated enumerations.

[0073] The terms first, second, third, etc., may be used herein to describe multiple elements, components, regions, layers, and / or segments, but these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another region, layer, or segment. Terms such as “first,” “second,” and other numerical terms do not imply order or sequence unless the context clearly indicates otherwise. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as a second element, component, region, layer, or segment without departing from the teachings of the exemplary configuration.

[0074] In one configuration, a fluid-filled chamber is provided, comprising a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is fixed to the first barrier layer to define an internal void between the first and second barrier layers. The internal void accommodates a predetermined volume of fluid. The foam structure and the tensile member are disposed within the internal void, whereby the tensile member comprises a plurality of fibers extending in a first direction between the first and second barrier layers.

[0075] Implementations of this disclosure may include one or more of the following optional features. In some implementations, the tensile member is disposed between one of the first and second barrier layers and the foam structure. In some instances, the tensile member is attached to one of the first and second barrier layers, the foam structure is attached to the other of the first and second barrier layers, and / or the tensile member is attached to the foam structure.

[0076] The foam structure can be attached to the tensile member at attachment points spaced apart from the first and second barrier layers.

[0077] In some configurations, the foam structure includes a first foam layer and a second foam layer. The first foam layer may be attached to a first barrier layer, and the second foam layer may be attached to a second barrier layer. In some implementations, a tensile member may be disposed between the first foam layer and the second foam layer.

[0078] Alternatively or concurrently, the tensile member may include a first substrate and a second substrate. The plurality of fibers may extend between the first substrate and the second substrate and may be attached to the first substrate and the second substrate. In some instances, the first substrate may be attached to one of a first barrier layer and a second barrier layer, and the second substrate may be attached to a foam layer.

[0079] A method is also provided, comprising forming a first barrier layer, forming a second barrier layer, and securing the first barrier layer to the second barrier layer to define an internal void disposed between the first and second barrier layers. The method further includes positioning a foam structure within the internal void, positioning a tensile member having a first substrate, a second substrate, and a plurality of fibers extending between the first and second substrates within the internal void and positioned between one of the first and second barrier layers and the foam structure, and providing a predetermined volume of fluid to the internal void.

[0080] In one configuration, positioning the tensile member between one of the first and second barrier layers and the foam structure includes attaching one of the first and second substrates to the foam structure.

[0081] The method may further include attaching one of a first substrate and a second substrate to one of a first barrier layer and a second barrier layer, and attaching a foam structure to the other of the first barrier layer and the second barrier layer.

[0082] The tensile member can be attached to the foam structure. Furthermore, the foam structure can be attached to the tensile member at attachment locations. Attaching the foam structure to the tensile member at attachment locations can include attaching the foam structure to the tensile member at attachment locations spaced apart from the first and second barrier layers.

[0083] Positioning the foam structure may include positioning a first foam layer and positioning a second foam layer. The method may further include attaching the first foam layer to a first barrier layer and attaching the second foam layer to a second barrier layer, wherein positioning the tensile member includes positioning the tensile member between the first and second foam layers. The method may also include attaching one of a first substrate and a second substrate to the first foam layer and the other of the first substrate and the second substrate to the second foam layer.

[0084] In one configuration, the method may include providing a foam structure having an arcuate surface, and may further include attaching the arcuate surface to one of a first barrier layer and a second barrier layer.

[0085] Reference Figures 1A to 1B A footwear article 10 is provided, which may include an upper 20 and a sole structure 22. The sole structure 22 is attached to the upper 20 in a manner that prevents the upper 20 from contacting the ground during normal use of the footwear article 10 and is positioned between the upper 20 and the ground.

[0086] The upper 20 and sole structure 22 extend from the heel end 12 along the Y-axis to the forefoot end 14 and from the lateral side 16 along the X-axis to the medial side 18. The heel end 12 may correspond to the posterior portion of the foot, including the calcaneus. The forefoot end 14 may correspond to the toes and the joints connecting the metatarsals to the phalanges of the foot. The lateral side 16 and the medial side 18 may respectively correspond to the opposite sides of the footwear 10 extending from the heel end 12 to the forefoot end 14.

[0087] The upper 20 may include a body 26, a tongue 30, a fastening system 32, and an insole 34. Different materials may form the body 26 of the upper 20, including one or more of foam materials, textiles, leather, and synthetic leather, joined together to form the shape of the upper 20. In this regard, the body 26 may be formed of one or more materials that are stitched or bonded together to form a cavity 24 that receives and secures the foot to support it on the sole structure 22. Suitable materials for the body 26 may include, but are not limited to, textiles, foam, leather, and synthetic leather. These materials may be selected and positioned to impart durability, breathability, abrasion resistance, flexibility, and comfort to the foot when placed within the cavity 24.

[0088] The body 26 of the upper 20 can be formed to define a foot receiving opening 28 in the heel end 12 of the upper 20. The foot receiving opening 28 provides an entrance to the shoe cavity 24. For example, the foot receiving opening 28 can receive a foot to secure it within the shoe cavity 24 and facilitate entry and exit of the foot from the shoe cavity 24. Without departing from the scope of this disclosure, the body 26 and the foot receiving opening 28 can be combined with… Figures 1A to 1B The different configurations are illustrated in the figure. For example, in some configurations, the body 26 may be made of less material and the foot receiving opening 28 may be larger and / or have a different shape.

[0089] The tongue 30 can extend between the shoe cavity 24 and the fastening system 32. Similar to the body 26 of the upper 20, the tongue 30 can be composed of different materials joined together. In this regard, the tongue 30 can be formed separately from the body 26 but attached to the body 26 in a manner that allows the user of the footwear 10 to change the size of the foot receiving opening 28. For example, the user of the footwear 10 can manipulate the position of the tongue 30 to allow his or her foot to easily enter or exit the shoe cavity 24 through the foot receiving opening 28.

[0090] Fastening system 32 may include one or more fasteners (e.g., shoelaces 36) extending along the upper 20. In some configurations, the upper 20 may include holes, such as holes 38, and / or other engagement features, such as mesh loops or fabric for receiving fasteners. The user of footwear article 10 can tighten or loosen the fasteners through the plurality of holes 38 to tighten or loosen the body 26 and tongue 30 of the upper 20 surrounding the user's foot to allow his or her foot to enter or exit the shoe cavity 24. Although the fastener is generally shown and described herein as shoelaces 36, it will be understood that within the scope of this disclosure, the fastener may also include strips, cords, hook-and-loop fasteners, or any other suitable type of fastener.

[0091] The insole 34 can be positioned within the shoe cavity 24 along a portion of the body 26 of the upper 20. In some configurations, the insole 34 is positioned within the shoe cavity 24 to contact the sole of the user's foot to enhance the comfort of the footwear 10.

[0092] Although footwear article 10 is shown and described herein as including a tongue 30, a fastening system 32, and an insole 34, it will be understood that the tongue 30, fastening system 32, and insole 34 are optional features of footwear article 10. Furthermore, the size, shape, position, and other characteristics of each can vary significantly between different implementations of footwear article 10.

[0093] The sole structure 22 may include, for example, different layers, such as an outsole 42, a midsole 40, and an insole or insole 34. Each layer may be used for a specific function. For example, as described above, the insole or insole 34 may be designed to contact the foot and provide enhanced comfort. In this regard, the insole 34 may include a layer formed into the sole structure 22 such that the insole 34 is configured in an assembled configuration between the midsole 40 and the upper 20.

[0094] The outsole 42 is typically positioned on the bottom surface of the footwear article 10. Specifically, the outsole 42 may include a layer coupled to the midsole 40, such that the outsole 42 contacts the ground during normal use. In this respect, the outsole 42 can provide a degree of cushioning for the foot during use of the footwear article 10. Furthermore, the outsole 42 may be formed of an abrasion-resistant material such as rubber to protect the footwear article 10 during use and provide reliable grip.

[0095] The midsole 40 may include a body 44 and one or more fluid-filled chambers 46, and the midsole 40 may be disposed between the outsole 42 and the upper 20 and / or the insole 34. In some configurations, the midsole 40 may extend along the Y-axis between the heel end 12 and the forefoot end 14 and along the X-axis between the lateral side 16 and the medial side 18 to improve various performance-related characteristics of the footwear article 10. For example, the midsole 40 may provide a stability and cushioning system for the user's foot.

[0096] The body 44 of the midsole 40 may be at least partially formed of a foam polymer material such as polyurethane, ethyl vinyl acetate copolymer, or other materials, and the body 44 may include at least partially a first (e.g., upper) chamber contact surface 86, a second (e.g., lower) chamber contact surface 88, and a third (e.g., side or periphery) chamber contact surface 90 (each chamber contact surface, for example, in...). Figure 3B and Figure 3C Cavity 47 (as shown in the image) Figure 3B ).

[0097] A fluid-filled chamber 46 may be disposed within a cavity 47 of the body 44, and the fluid-filled chamber 46 may include a first barrier layer 52, a second barrier layer 54, a foam structure (e.g., a layer) 60, and a tensile member 70. The first barrier layer 52 may be coupled to the second barrier layer 54 at a joint 56. In some configurations, the first barrier layer 52 is sealed to the second barrier layer 54 at the joint 56 such that the first barrier layer 52 and the second barrier layer 54 together define an internal void 58. The internal void 58 may contain one or more fluids. For example, air, nitrogen, hexafluoroethane, sulfur hexafluoride, other gases, other fluids, or mixtures thereof may fill the fluid-filled chamber 46. The first barrier layer 52 and the second barrier layer 54 (including the sealing joint 56 therebetween) may maintain the fluid within the internal void 58 at ambient pressure, or alternatively, may maintain the fluid within the internal void 58 at a pressure greater than ambient pressure. The fluid-filled chamber 46 (including its pressure) provides improved cushioning by absorbing the impact force generated when the outsole 42 hits the ground during use.

[0098] In some configurations, the fluid-filled chamber 46 may extend a width W46 along the X-axis and be substantially centered within the body 44 of the midsole 40 along both the Z and X axes. The width W46 of the fluid-filled chamber 46 may extend along the X-axis across a large portion (e.g., greater than 50% and less than 100%) of the midsole 40. In this regard, it will be understood that, without departing from the scope of this disclosure, the width W46 of the fluid-filled chamber 46 may be greater than or less than [the specified width]. Figure 1B The width shown is W46.

[0099] Without departing from the scope of this disclosure, the configuration (e.g., size, location, and / or number) of the fluid-filled chambers 46 located within the body 44 of the midsole 40 may be consistent with... Figure 1B and Figure 2A The locations illustrated in the figures differ. For example, the fluid-filled chamber 46 may be eccentrically positioned relative to the body 44 along the X, Y, and / or Z axes. Additionally, within the scope of this disclosure, the midsole 40 may include more than one fluid-filled chamber 46 with different designs. Figure 2A As illustrated, in some configurations, the fluid filling chamber 46 includes a length L46 extending from the heel end 12 along the Y-axis of the footwear 10 to the forefoot end 14.

[0100] like Figure 2B As illustrated herein, a footwear article 100 is provided, and the footwear article 100 includes a fluid filling chamber 48. Except as otherwise shown or described herein, the footwear article 100 and the fluid filling chamber 48 may be substantially similar to footwear article 10 and fluid filling chamber 46, respectively. The fluid filling chamber 48 may be disposed within the heel end 12 of the footwear article 100 and may have a length L48 that spans only a portion of the distance between the heel end 12 and the forefoot end 14 along the Y-axis.

[0101] like Figure 2C As illustrated, a footwear article 200 is provided, and the footwear article 200 includes a fluid filling chamber 50. Except as otherwise shown or described herein, the footwear article 200 and the fluid filling chamber 50 may be substantially similar to footwear article 10 and fluid filling chamber 46, respectively. The fluid filling chamber 50 may be disposed within the forefoot end 14 of the footwear article 200 and may have a length L50 along the Y-axis spanning only a portion of the distance between the heel end 12 and the forefoot end 14.

[0102] exist Figure 2DAs illustrated herein, footwear article 300 is provided, and footwear article 300 includes a fluid filling chamber 48 and a fluid filling chamber 50. Except as otherwise shown or described herein, footwear article 300 may be substantially similar to footwear article 10. Although footwear articles 10, 100, 200, and 300 are shown and described herein as having one or two fluid filling chambers 46, 48, and / or 50, it will be understood that within the scope of this disclosure, footwear articles may include more than two fluid filling chambers 46, 48, and / or 50.

[0103] The foam structure 60 can be disposed within the internal voids 58 of the fluid-filled chamber 46. For example... Figure 1B As illustrated, in some configurations, the foam structure 60 may be positioned adjacent to the second barrier layer 54 such that the first (e.g., lower) surface 602 of the foam structure 60 engages the first (e.g., upper) surface 55 of the second barrier layer 54 at the first attachment portion 96. The foam structure 60 may be formed of an open-cell foam core, such as those disclosed in U.S. Patent Nos. 4,874,640 and 5,235,715, the entire disclosure of which is incorporated herein by reference. Alternatively, the foam structure 60 may be formed of one or more flexible materials—such as mesh materials, nylon materials, ethylene-vinyl acetate copolymers, or any other suitable material that provides cushioning and can be shaped to form the foam structure 60. The material of the foam structure 60 provides improved cushioning performance by absorbing the impact force generated when the outsole 42 impacts the ground during use. Using high-density foam can increase the strength of the foam structure 60 and increase the duration of impact force propagation when the outsole 42 impacts the ground. Furthermore, combining the foam structure 60 with the fluid-filled chamber 46 in the footwear article 10 provides responsive cushioning due to the foam structure 60 and soft cushioning due to the fluid contained within the chamber 46. These components can advantageously be installed simultaneously in the footwear article 10 when forming the fluid-filled chamber 46.

[0104] Reference Figure 3C The tensile member 70 may be disposed within the internal void 58 of the fluid-filled chamber 46 and may include a first (e.g., upper) base 82, a second (e.g., lower) base 84, and a plurality of individual tensile fibers 85 extending between the first base 82 and the second base 84. Figure 1B and Figure 3BAs illustrated, in some configurations, the tensile member 70 is disposed relative to the Z-axis between the foam structure 60 and the first barrier layer 52, such that: (i) the first base 82 engages the second (e.g., lower) surface 53 of the first barrier layer 52 at the second attachment 94 and (ii) the second base 84 engages the second (e.g., upper) surface 601 of the foam structure 60 at the third attachment 97. The first base 82 and the second base 84 may include a substantially flat configuration. Thus, the attachment 94 between the tensile member 70 (at the first base 82) and the first barrier layer 52, and the attachment 97 between the tensile member 70 (at the second base 84) and the foam structure 60, may be formed such that substantially all of the first base 82 and the second base 84 contact the second surface 53 of the first barrier layer 52 and the second surface 601 of the foam structure 60, respectively.

[0105] The plurality of individual tensile fibers 85 may include multiple dimensions (e.g., diameter, length along the Z-axis), cross-sectional shapes (e.g., circular, rectangular, or other polygonal), and / or materials that can be readily deflected when compressive force is applied to the tensile member 70. For example, as illustrated throughout the figures, the distance along the Z-axis between the first substrate 82 and the second substrate 84 can vary, such that the length of the tensile fiber 85 measured along the Z-axis can also vary between one tensile fiber 85 and another and / or between one configuration of the fluid-filled chamber 46 and another configuration of the fluid-filled chamber 46. When the fluid-filled chamber 46 and / or the tensile member 70 are in an intermediate state (i.e., no external force is applied to the fluid-filled chamber 46 and / or the tensile member 70), one or more of the plurality of individual tensile fibers 85 can withstand tension to maintain the desired shape of the fluid-filled chamber 46 by preventing or inhibiting the first barrier layer 52 from moving away from the second barrier layer 54 along the Z-axis (e.g., Figure 1B Tensile fiber 85 is under tension due to the fluid contained within fluid-filled chamber 46. Further details of tensile fiber 85 are described in U.S. Patent Nos. 4,906,502, 5,083,361, and 6,385,864, the entire disclosure of which is incorporated herein by reference.

[0106] Also refer to Figures 3A to 3CThe method of manufacturing footwear article 10 will now be described. A first barrier layer 52 and / or a second barrier layer 54 can be formed from a polymer (e.g., thermoplastic polyurethane) using various manufacturing techniques (e.g., injection molding). The first barrier layer 52 can be sealed to the second barrier layer 54 at a seam 56, such that the first barrier layer 52 and the second barrier layer 54 together define an internal void 58. Specifically, the first barrier layer 52 can be attached to the second barrier layer 54 using various fastening techniques—such as applying heat and / or pressure or applying adhesives. A foam structure 60 and a tensile member 70 can be positioned within the internal void 58 such that the plurality of fibers 85 extend between the first barrier layer 52 and the second barrier layer 54 in a first direction (e.g., along the Z-axis). In this regard, the foam structure 60 can be attached to the second barrier layer 54 at a first attachment 96. Additionally, the first substrate 82 can be attached to the first barrier layer 52 at the second attachment 94, and the second substrate 84 can be attached to the foam structure 60 at the third attachment 97. For example, a predetermined volume of fluid, such as air, nitrogen, hexafluoroethane, sulfur hexafluoride, or a mixture thereof, can be injected into the internal voids 58 to keep the fibers 85 taut. The fluid-filled chamber 46 can be arranged and fixed within the body 44 of the midsole 40. In particular, the fluid-filled chamber 46 can be fixed within the cavity 47 using various techniques—such as overmolding or adhesive bonding.

[0107] Reference Figures 4A to 4C Another footwear article 10b is shown. Except as otherwise provided herein, the structure and function of footwear article 10b may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10b and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0108] Footwear article 10b may include an upper 20 and a sole structure 22b. Sole structure 22b may include a midsole 40b and an outsole 42. Midsole 40b may include a fluid-filled chamber 46b located within a body 44.

[0109] Fluid-filled chamber 46b can be as Figures 2A to 2DAs shown, the fluid-filled chamber 46b can be located and oriented within the footwear article 10b at any position and orientation, and may include a first barrier layer 52, a second barrier layer 54, a foam structure 60, and a tensile member 70. The foam structure 60 may be configured adjacent to the first barrier layer 52 such that a second surface 601 of the foam structure 60 engages with a second surface 53 of the first barrier layer 52 at a fourth attachment 102. The tensile member 70 may be disposed relative to the Z-axis between the foam structure 60 and the second barrier layer 54 such that: (i) a second base 84 engages with a first surface 55 of the second barrier layer 54 at a fifth attachment 104, and (ii) a first base 82 engages with a first surface 602 of the foam structure 60 at a sixth attachment 106. The first base 82 and the second base 84 may include a substantially flat configuration. Therefore, the attachment portion 106 located between the tensile member 70 (at the first substrate 82) and the foam structure 60, and the attachment portion 104 located between the tensile member 70 (at the second substrate 84) and the second barrier layer 54, can be formed such that substantially all of the first substrate 82 and the second substrate 84 contact the first surface 602 of the foam structure 60 and the first surface 55 of the barrier layer 54, respectively. Additionally, the attachment portion 102 can allow substantially all of the first surface 601 of the foam structure 60 to contact the surface 53 of the first barrier layer 52.

Given that the method of manufacturing footwear article 10b is substantially similar to that of manufacturing footwear article 10, only the differences will be discussed here. During the method of manufacturing footwear article 10b, foam structure 60 may be attached to first barrier layer 52 at fourth attachment 102, first substrate 82 may be attached to foam structure 60 at sixth attachment 106, and second substrate 84 may be attached to second barrier layer 54 at fifth attachment 104. Once attached, a predetermined fluid may be supplied to fluid filling chamber 46b to keep the fibers 85 of tensile member 70 in a taut state.

[0111] Reference Figures 5A to 5C Another footwear article 10c is shown. Except as otherwise provided herein, the structure and function of footwear article 10c may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10c and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0112] Footwear product 10c may include an upper 20 and a sole structure 22c. Sole structure 22c may include a midsole 40c and an outsole 42. Midsole 40c may include a fluid-filled chamber 46c located within a body 44.

[0113] Fluid-filled chamber 46c can be as Figures 2A to 2D As shown, the fluid-filled chamber 46c can be located and oriented within the footwear article 10c at any position and orientation, and may include a first barrier layer 52, a second barrier layer 54, a foam structure 60, and one or more tensile members 70. Figure 5B As illustrated, in some configurations, the fluid-filled chamber 46c includes two tensile members 70. A first (e.g., upper) tensile member 72 of the tensile members 70 may be disposed relative to the Z-axis between the foam structure 60 and the first barrier layer 52, such that: (i) the first base 82 engages the second surface 53 of the first barrier layer 52 at the second attachment 94 and (ii) the second base 84 engages the second surface 601 of the foam structure 60 at the third attachment 97. A second (e.g., lower) tensile member 74 of the tensile members 70 may be disposed relative to the Z-axis between the foam structure 60 and the second barrier layer 54, such that: (i) the second base 84 engages the first surface 55 of the second barrier layer 54 at the fifth attachment 104 and (ii) the first base 82 engages the first surface 602 of the foam structure 60 at the sixth attachment 106. Thus, as Figure 5B and Figure 5C As illustrated, the foam structure 60 can be disposed between the first tensile member 72 and the second tensile member 74, such that the second surface 601 engages with the second base 84 of the first tensile member 72 and the first surface 602 engages with the first base 82 of the second tensile member 74.

[0114] Also refer to Figures 5A to 5C The method of manufacturing footwear article 10c will now be described. Since the method of manufacturing footwear article 10c is substantially similar to that of manufacturing footwear article 10, only these differences will be discussed here. During the method of manufacturing footwear article 10c, a foam structure 60 may be positioned between and attached to a first tensile member 72 and a second tensile member 74. Specifically, a second base 84 of the first tensile member 72 may be attached to a second surface 601 of the foam structure 60 at a third attachment 97, and a first base 82 of the second tensile member 74 may be attached to a first surface 602 of the foam structure 60 at a sixth attachment 106. Additionally, a first base 82 of the first tensile member 72 may be attached to a first barrier layer 52 at a second attachment 94, and a second base 84 of the second tensile member 74 may be attached to a second barrier layer 54 at a fifth attachment 104.

[0115] Reference Figures 6A to 6CAnother footwear article 10d is shown. Except as otherwise provided herein, the structure and function of footwear article 10d may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10d and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0116] Footwear product 10d may include an upper 20 and a sole structure 22d. Sole structure 22d may include a midsole 40d and an outsole 42. Midsole 40d may include a fluid-filled chamber 46d located within a body 44.

[0117] Fluid-filled chamber 46d can be as Figures 2A to 2D As shown, the fluid-filled chamber 46d can be located at any position and orientation within the footwear article 10d, and may include a first barrier layer 52, a second barrier layer 54, a tensile member 70, and one or more foam structures 60. Figure 6B As illustrated, in some configurations, the fluid-filled chamber 46d includes two foam structures 60. A first (e.g., upper) foam structure 62 of the foam structure 60 may be configured to abut a first barrier layer 52, such that a second surface 601 of the foam structure 60 engages with a second surface 53 of the first barrier layer 52 at a fourth attachment 102. A second (e.g., lower) foam structure 64 of the foam structure 60 may be configured to abut a second barrier layer 54, such that a first surface 602 of the foam structure 60 engages with a first surface 55 of the second barrier layer 54 at a first attachment 96. Thus, as... Figure 6B and Figure 6C As illustrated, the tensile member 70 can be disposed between the first foam structure 62 and the second foam structure 64, such that the first substrate 82 engages with the first surface 602 of the first foam structure 62 and the second substrate 84 engages with the second surface 601 of the second foam structure 64.

[0118] Also refer to Figures 6A to 6CThe method of manufacturing footwear article 10d will now be described. Since the method of manufacturing footwear article 10d is substantially similar to that of manufacturing footwear article 10, only these differences will be discussed here. During the method of manufacturing footwear article 10d, a tensile member 70 may be positioned between and attached to a first foam structure 62 and a second foam structure 64. Specifically, the second base 84 of the tensile member 70 may be attached to the second surface 601 of the second foam structure 64 at a third attachment 97, and the first base 82 of the tensile member 70 may be attached to the first surface 602 of the first foam structure 62 at a sixth attachment 106. Additionally, the first surface 602 of the second foam structure 64 may be attached to the second barrier layer 54 at a first attachment 96, and the second surface 601 of the first foam structure 62 may be attached to the first barrier layer 52 at a fourth attachment 102.

[0119] Reference Figures 7A to 7D Another footwear article 10e is shown. Except as otherwise provided herein, the structure and function of footwear article 10e may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the components associated with footwear article 10e and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same components, while the same reference numerals including letter extensions are used to identify those components that have been modified.

[0120] Footwear product 10e may include an upper 20 and a sole structure 22e. Sole structure 22e may include a midsole 40e and an outsole 42. Midsole 40e may include a fluid-filled chamber 46e located within a body 44e. (Example...) Figures 7B to 7D As illustrated, the body 44e may include a cavity 47e at least partially defined by a first (e.g., upper) chamber contact surface 86e, a second chamber contact surface 88, and a third chamber contact surface 90. The first chamber contact surface 86e may be substantially convex in a direction extending along the X-axis and substantially flat in a direction extending along the Y-axis.

[0121] Fluid-filled chamber 46e can be as Figures 2A to 2DAs shown, the fluid-filled chamber 46e can be located and oriented at any position within the footwear article 10e, and may include a first barrier layer 52g, a second barrier layer 54, a foam structure 60e, and a tensile member 70. The second surface 53e of the first barrier layer 52e may be substantially convex in the direction extending along the X-axis and substantially flat in the direction extending along the Y-axis. The surface of the first barrier layer 52e opposite to the second surface 53e may be substantially concave in the direction extending along the X-axis and substantially flat in the direction extending along the Y-axis. In this respect, the concavity of the surface opposite to the second surface 53e may be equal to and match the convexity of the first chamber contact surface 86e of the body 44e.

[0122] The foam structure 60e can be placed within the internal voids 58e of the fluid-filled chamber 46e. For example... Figure 7B and Figure 7C As illustrated, in some configurations, the foam structure 60e is positioned adjacent to the first barrier layer 52e such that the second surface 601e of the foam structure 60e engages the second surface 53e of the first barrier layer 52e at the fourth attachment portion 102e. The second surface 601e of the foam structure 60e may be substantially concave in a direction extending along the X-axis. In this respect, the concavity of the second surface 601e may be equal to and match the convexity of the second surface 53e of the first barrier layer 52e. Thus, the fourth attachment portion 102e allows substantially the entire first surface 601e of the foam structure 60e to contact the surface 53e of the first barrier layer 52e. The tensile member 70 may be disposed relative to the Z-axis between the foam structure 60e and the second barrier layer 54 such that: (i) the second substrate 84 engages the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104 and (ii) the first substrate 82 engages the first surface 602 of the foam structure 60e at the sixth attachment portion 106.

[0123] Reference Figures 8A to 8D Another footwear article 10f is shown. Except as otherwise provided herein, the structure and function of footwear article 10f may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10f and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0124] Footwear article 10f may include an upper 20 and a sole structure 22f. Sole structure 22f may include a midsole 40f and an outsole 42. Midsole 40f may include a fluid-filled chamber 46f located within a body 44f. (Example...) Figure 7BAs illustrated, the body 44g may include a cavity 47f at least partially defined by a first (e.g., upper) chamber contact surface 86f, a second (e.g., lower) chamber contact surface 88f, and a third (e.g., peripheral) chamber contact surface 90f. The first chamber contact surface 86f may be substantially flat and include a laterally extending portion 110 near the heel end 12 of the footwear article 10f. Figure 8D In some configurations, the first chamber contact surface 86f may extend from the heel end 12 along the Y-axis toward the second chamber contact surface 88f to the forefoot end 14. For example, in some configurations, the first chamber contact surface 86f may be inclined toward the second chamber contact surface 88f. In other configurations, the first chamber contact surface 86f may include a recessed shape extending toward the second chamber contact surface 88f. Figure 8D As illustrated, the lateral extension 110 can extend away from the second chamber contact surface 88f in a direction generally parallel to the Z-axis. The second chamber contact surface 88f can be substantially flat. The third chamber contact surface 90f can extend from the first chamber contact surface 86f and the second chamber contact surface 86f and extend between the first chamber contact surface 86f and the second chamber contact surface 86f. In this respect, the distance by which the third chamber contact surface 90f extends away from the second chamber contact surface 88f at the heel end 12 can be greater than the distance by which it extends away from the second chamber contact surface 88f at the forefoot end 14. Therefore, the lateral extension 110f of the third chamber contact surface 90f and the first chamber contact surface 86f can define the lateral extension 112 of the cavity 47f.

[0125] Fluid-filled chamber 46f can be as Figures 2A to 2D As shown, the fluid-filled chamber 46f can be located and oriented within the footwear article 10f at any position and orientation, and may include a first barrier layer 52f, a second barrier layer 54f, a foam structure 60f, and a tensile member 70. The second surface 53f of the first barrier layer 52f may include dimensions and shapes corresponding to and matching those of the first chamber contact surface 86f and the third chamber contact surface 90f of the body 44f. In this regard, as... Figure 8D As illustrated, the first barrier layer 52f may include a U-shaped portion 114, which is disposed in the lateral extension 112 of the cavity 47f in the assembly configuration, such that the internal void 58f includes the lateral extension 116.

[0126] The foam structure 60f can be placed within the internal voids 58f of the fluid-filled chamber 46f. For example... Figure 8B and Figure 8CAs illustrated, in some configurations, the foam structure 60f is positioned adjacent to the first barrier layer 52f, such that the second surface 601f of the foam structure 60f engages with the second surface 53f of the first barrier layer 52f at the fourth attachment portion 102f. The second surface 601f of the foam structure 60f may include dimensions and shapes corresponding to and matching those of the second surface 53f of the first barrier layer 52f. In this regard, as... Figure 8B and Figure 8D As illustrated, the second surface 601f can extend upward along the Z-axis to partially define the flange portion 118 of the foam structure 60f. In an assembled configuration, the flange portion 118 can be disposed within the lateral extension portion 116 of the internal void 58f. The tensile member 70 can be disposed relative to the Z-axis between the foam structure 60f and the second barrier layer 54f such that: (i) the second substrate 84 engages the first surface 55f of the second barrier layer 54f at the fifth attachment portion 104f and (ii) the first substrate 82 engages the first surface 602f of the foam structure 60f at the sixth attachment portion 106f.

[0128] The footwear product 10g may include an upper 20 and a sole structure 22g. The sole structure 22g may include a midsole 40g and an outsole 42. The midsole 40g may include a fluid-filled chamber 46g located within the body 44.

[0129] The fluid-filled chamber 46g can be as Figures 2A to 2D As shown, the fluid-filled chamber 46g can be located and oriented at any position within the footwear article 10g, and may include a first barrier layer 52, a second barrier layer 54, one or more foam structures 60g, and one or more tensile members 70g. The first foam structure 62g and the second foam structure 64g of the foam structures 60g may be disposed within the internal voids 58g of the fluid-filled chamber 46g. Figure 9EAs illustrated, the first foam structure 62g can be configured to be adjacent to the first barrier layer 52, such that the second surface 601g of the first foam structure 62g is joined to the second surface 53 of the first barrier layer 52 at the fourth attachment portion 102g. The second foam structure 64g can be configured to be adjacent to the second barrier layer 54, such that the first surface 602g of the second foam structure 64g is joined to the first surface 55 of the second barrier layer 54 at the first attachment portion 96g.

[0130] The first tensile member 72g and the second tensile member 74g of the tensile member 70g can be disposed within the internal void 58g of the fluid-filled chamber 46g. The first tensile member 72g can be disposed relative to the Z-axis between the second foam structure 64g and the first barrier layer 52, such that: (i) the first substrate 82g engages the second surface 53 of the first barrier layer 52 at the second attachment portion 94g and (ii) the second substrate 84g engages the second surface 601g of the second foam structure 64g at the third attachment portion 97g. The second tensile member 74g can be disposed relative to the Z-axis between the first foam structure 62g and the first barrier layer 52, such that: (i) the second substrate 84 engages the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104g and (ii) the first substrate 82g engages the first surface 602g of the first foam structure 62g at the sixth attachment portion 106g.

[0131] like Figure 9E As illustrated, the first foam structure 62g and the second tensile member 74g extend from the heel end 12 along the Y-axis to a midpoint 120 located between the heel end 12 and the foreleg end 14. The second foam structure 64g and the first tensile member 72g extend from the foreleg end 14 along the Y-axis to the midpoint 120. Therefore, as illustrated, the first foam structure 62g may be adjacent to and / or opposite the first tensile member 72g at the midpoint 120, and the second foam structure 64g may be adjacent to and / or opposite the second tensile member 74g at the midpoint 120. If the first foam structure 62g is adjacent to the first tensile member 72g, these elements 62g and 72g can be attached to each other. Similarly, if the second foam structure 64g is adjacent to the second tensile member 74g, these elements 64g and 74g can be attached to each other.

[0132] In some configurations, the intermediate position 120 may be centrally located within the fluid-filled chamber 46g along the Y-axis, such that the lengths along the Y-axis of the first foam structure 62g, the second foam structure 64g, the first tensile member 72g, and the second tensile member 74g are substantially equal to each other. In other configurations, the intermediate position 120 may be offset from the center of the fluid-filled chamber 46g along the Y-axis, such that the length along the Y-axis of one or more of the first foam structure 62g, the second foam structure 64g, the first tensile member 72g, and the second tensile member 74g may differ from the length along the Y-axis of one or more of the other of the first foam structure 62g, the second foam structure 64g, the first tensile member 72g, and the second tensile member 74g.

[0133] Reference Figures 10A to 10E Another footwear article 10h is shown. Except as otherwise provided herein, the structure and function of footwear article 10h may be substantially similar to those of footwear article 10.

[0134] Footwear product 10h may include an upper 20 and a sole structure 22h. Sole structure 22h may include a midsole 40h and an outsole 42. Midsole 40h may include a fluid-filled chamber 46h located within the body 44.

[0135] The fluid-filled chamber can be filled for 46 hours as follows Figures 2A to 2D As shown, the fluid filling chamber 46h can be located at any position and orientation within the footwear article 10h, and may include a first barrier layer 52, a second barrier layer 54, one or more foam structures 60h, and one or more tensile members 70h. The first foam structure 62h and the second foam structure 64h of the foam structures 60h may be disposed within the internal void 58h of the fluid filling chamber 46h. Figure 10E As illustrated, the first foam structure 62h can be configured to be adjacent to the first barrier layer 52, such that the second surface 601h of the first foam structure 62h is joined to the second surface 53 of the first barrier layer 52 at the fourth attachment portion 102h.

[0136] The first tensile member 72h and the second tensile member 74h of the tensile member 70h can be disposed within the internal void 58h of the fluid filling chamber 46h. The first tensile member 72h can be disposed relative to the Z-axis between the second foam structure 64h and the first barrier layer 52, such that: (i) the first substrate 82h engages the second surface 53 of the first barrier layer 52 at the second attachment portion 94h and (ii) the second substrate 84h engages the second surface 601h of the second foam structure 64h at the third attachment portion 97h. The second tensile member 74h can be disposed relative to the Z-axis between the first foam structure 62h and the first barrier layer 52, such that: (i) the second substrate 84 engages the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104h and (ii) the first substrate 82h engages the first surface 602h of the first foam structure 62h at the sixth attachment portion 106h.

[0137] like Figure 10E As illustrated, the first foam structure 62h and the second tensile member 74h can extend from the front end 14 along the Y-axis to the intermediate position 120. The second foam structure 64h and the first tensile member 72h can extend from the heel end 12 along the Y-axis to the intermediate position 120. Therefore, as illustrated, the first foam structure 62h can be adjacent to and / or opposite the first tensile member 72h at the intermediate position 120, and the second foam structure 64h can be adjacent to and / or opposite the second tensile member 74h at the intermediate position 120. If the first foam structure 62h is adjacent to the first tensile member 72h, these elements 62h, 72h can be attached to each other. Similarly, if the second foam structure 64h is adjacent to the second tensile member 74h, these elements 64h, 74h can be attached to each other.

[0139] Footwear article 10i may include an upper 20 and a sole structure 22i. Sole structure 22i may include a midsole 40i and an outsole 42. Midsole 40i may include a fluid-filled chamber 46i located within a body 44.

[0140] The fluid-filled chamber 46i can be like Figures 2A to 2DAs shown, the fluid filling chamber 46i can be located and oriented at any position within the footwear article 10i, and may include a first barrier layer 52, a second barrier layer 54, one or more foam structures 60i, and one or more tensile members 70i. The first foam structure 62i and the second foam structure 64i of the foam structures 60i may be disposed within the internal voids 58i of the fluid filling chamber 46i. Figure 11F As illustrated, the first foam structure 62i and the second foam structure 64i can be configured to be adjacent to the first barrier layer 52, such that the second surface 601i of each of the first foam structure 62i and the second foam structure 64i engages with the second surface 53 of the first barrier layer 52 at the fourth attachment portion 102i.

[0141] The first tensile member 72i, the second tensile member 74i, and the third tensile member 76i of the tensile member 70i can be disposed within the internal void 58i of the fluid-filled chamber 46i. The first tensile member 72i and the second tensile member 74i can be disposed relative to the Z-axis between the first barrier layer 52 and the first foam structure 62i and between the first barrier layer 52 and the second foam structure 64i, respectively, such that: (i) the second base 84 of each of the first tensile member 72i and the second tensile member 74i engages with the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104i and (ii) the first base 82i of each of the first tensile member 72i and the second tensile member 74i engages with the first surface 602i of the first foam structure 62i at the sixth attachment portion 106i. The third tensile member 76i can be disposed along the Y-axis between the first foam structure 62i and the second foam structure 64i and between the first tensile member 72i and the second tensile member 74i. The first base 82i of the third tensile member 76i can be joined to the second surface 53 of the first barrier layer 52, and the second base 84i of the third tensile member 76i can be joined to the first surface 55 of the second barrier layer 54. In this regard, the height of the third tensile member 76i along the Z-axis can be substantially equal to (i) the combined height of the first foam structure 62i and the first tensile member 72i, and (ii) the combined height of the second foam structure 64i and the second tensile member 74i.

[0142] like Figure 11FAs illustrated, the first foam structure 62i and the first tensile member 72i extend from the heel end 12 along the Y-axis to a first intermediate position 120i located between the heel end 12 and the foreleg end 14. The second foam structure 64i and the second tensile member 74i extend from the foreleg end 14 along the Y-axis to a second intermediate position 122. The third tensile member 76i extends from the first intermediate position 120 to the second intermediate position 122. Therefore, as illustrated, the first foam structure 62i and the first tensile member 72i may be adjacent to and / or opposite the proximal end of the third tensile member 76i at the first intermediate position 120, and the second foam structure 64i and the second tensile member 74i may be adjacent to and / or opposite the third tensile member 76i at the second intermediate position 122. The first foam structure 62i and the first tensile member 72i can be attached to the third tensile member 76i at the first intermediate position 120, and the second foam structure 64i and the second tensile member 74i can be attached to the third tensile member 76i at the second intermediate position 122.

[0143] In some configurations, the first intermediate position 120 and / or the second intermediate position 122 may be offset from the central portion of the fluid-filled chamber 46i along the Y-axis, such that the third tensile member 76i is positioned at the central portion of the fluid-filled chamber 46i along the Y-axis. In other configurations, one or more of the first intermediate position 120 and the second intermediate position 122 may alternatively be positioned relative to the central portion of the fluid-filled chamber 46i such that the third tensile member 76i is offset from the central portion of the fluid-filled chamber 46i relative to the Y-axis.

[0144] Reference Figures 12A to 12D Another footwear article 10j is shown. Except as otherwise provided herein, the structure and function of footwear article 10j may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10j and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0145] Footwear product 10j may include an upper 20 and a sole structure 22j. The sole structure 22j may include a midsole 40j and an outsole 42. The midsole 40j may include a fluid-filled chamber 46j located within a body 44j. (Example...) Figure 12B As illustrated, the body 44j may include a cavity 47j at least partially defined by a first (e.g., upper) chamber contact surface 86j, a second (e.g., lower) chamber contact surface 88j, and a third (e.g., peripheral) chamber contact surface 90j. The first chamber contact surface 86j may be substantially flat and include a laterally extending portion 110 near the heel end 12 of the footwear article 10j. Figure 12D In some configurations, the first chamber contact surface 86j may extend from the heel end 12 along the Y-axis toward the second chamber contact surface 88j to the forefoot end 14. For example, in some configurations, the first chamber contact surface 86j may be inclined toward the second chamber contact surface 88f. In other configurations, the first chamber contact surface 86j may include a recessed shape extending toward the second chamber contact surface 88f. Figure 12D As illustrated, the lateral extension 110 can extend away from the second chamber contact surface 88j in a direction generally parallel to the Z-axis. The second chamber contact surface 88j can be substantially flat. The third chamber contact surface 90j can extend from the first chamber contact surface 86j and the second chamber contact surface 88j and extends between the first chamber contact surface 86j and the second chamber contact surface 88j. In this respect, the distance by which the third chamber contact surface 90j extends away from the second chamber contact surface 88j at the heel end 12 can be greater than the distance by which it extends away from the second chamber contact surface 88j at the foreleg end 14. Therefore, the lateral extension 110 of the third chamber contact surface 90j and the first chamber contact surface 86j can define the lateral extension 112 of the cavity 47f.

[0146] Fluid-filled chamber 46j can be as Figures 2A to 2D As shown, the fluid-filled chamber 46j can be located and oriented at any position within the footwear article 10j, and may include a first barrier layer 52j, a second barrier layer 54j, a foam structure 60j, and a tensile member 70. The second surface 53j of the first barrier layer 52j may include dimensions and shapes corresponding to and matching those of the first chamber contact surface 86j and the third chamber contact surface 90j of the body 44j. In this regard, as... Figure 12D As illustrated, the first barrier layer 52j may include a U-shaped portion 114, which is disposed in the lateral extension 112 of the cavity 47j in the assembly configuration, such that the internal void 58j includes the lateral extension 116.

[0147] The foam structure 60j can be placed within the internal voids 58j of the fluid-filled chamber 46j. For example... Figure 12B and Figure 12C As illustrated in the figure, in some configurations, the foam structure 60j is positioned adjacent to the first barrier layer 52j, such that the second surface 601j of the foam structure 60j engages with the second surface 53j of the first barrier layer 52j at the fourth attachment portion 102j. The second surface 601j of the foam structure 60j may include dimensions and shapes corresponding to and matching those of the second surface 53j of the first barrier layer 52j. In this regard, as... Figure 12B and Figure 12D As illustrated, the second surface 601j can extend upward along the Z-axis to partially define the flange portion 118 of the foam structure 60j. Additionally, refer to... Figure 12C The second surface 601j of the foam structure 60j can be substantially concave in the direction extending along the X-axis. In this respect, the concavity of the second surface 601j can be equal to and match the convexity of the second surface 53j of the first barrier layer 52j. Therefore, the fourth attachment portion 102j can make the entire first surface 601j of the foam structure 60j contact the surface 53j of the first barrier layer 52j. In the assembly configuration, the flange portion 118 can be disposed within the lateral extension portion 116 of the internal void 58j. The tensile member 70 can be disposed relative to the Z-axis between the foam structure 60j and the second barrier layer 54j such that: (i) the second base 84 engages the first surface 55j of the second barrier layer 54j at the fifth attachment portion 104j and (ii) the first base 82 engages the first surface 602j of the foam structure 60j at the sixth attachment portion 106j.

[0148] Reference Figures 13A to 13D Another footwear article 10k is shown. Except as otherwise provided herein, the structure and function of footwear article 10k may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10k and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0149] Footwear product 10k may include an upper 20 and a sole structure 22k. The sole structure 22k may include a midsole 40k and an outsole 42. The midsole 40k may include a fluid-filled chamber 46k located within a body 44.

[0150] The fluid-filled chamber 46k can be as Figures 2A to 2D As shown, the fluid filling chamber 46k may be located in any position and orientation within the footwear article 10k, and may include a first barrier layer 52, a second barrier layer 54, a foam structure 60k, and one or more tensile members 70k.

[0151] The first tensile member 72k of the tensile member 70k can be disposed relative to the Z-axis between the first barrier layer 52 and the second barrier layer 54, such that: (i) the second base 84k engages the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104k and (ii) the first base 82k engages the second surface 53 of the first barrier layer 52 at the second attachment portion 94k. The first base 82k and the second base 84k can include a substantially flat configuration. Therefore, the attachment portion 94k located between the tensile member 72k (at the first base 82k) and the first barrier layer 52 and the attachment portion 104k located between the tensile member 72k (at the second base 84k) and the second barrier layer 54 can be formed such that substantially all of the first base 82k and the second base 84k contact the first surface 55 and the second surface 53, respectively.

[0152] The first tensile member 72k may include a channel 130 extending along the Z-axis from the first substrate 82k and the second substrate 84k, and extending along the Z-axis between the first substrate 82k and the second substrate 84k. In this regard, the channel 130 may extend from a first opening 132 formed in the first substrate 82k to a second opening 134 formed in the second substrate 84k. The first opening 132 and / or the second opening 134 may be centrally located within the first substrate 82k and the second substrate 84k relative to the X-axis and Y-axis, such that the tensile fiber 85 extends around the channel 130 and partially defines the channel 130.

[0153] A second tensile member 74k of the tensile member 70k may be disposed within the channel 130 and adjacent to the second barrier layer 54, such that the second base 84k of the second tensile member 74k engages with the first surface 55 of the second barrier layer 54 at the fifth attachment portion 104k. The second base 84k may include a substantially flat configuration. Therefore, the attachment portion 104k located between the second tensile member 74k (at the second base 84k) and the second barrier layer 54 may be formed such that substantially all of the second base 84k contacts the first surface 55 of the second barrier layer 54.

[0154] The foam structure 60k can be disposed within the channel 130 and located between the first barrier layer 52 and the second tensile member 74k, such that: (i) the second surface 601k of the foam structure 60k engages with the second surface 53 of the first barrier layer 52 at the fourth attachment portion 102k and (ii) the first surface 602k of the foam structure 60k engages with the first base 82k of the second tensile member 74k at the sixth attachment portion 106k. Therefore, as Figure 13DAs illustrated, the distance along the Z-axis between the first base 82k of the first tensile member 72k and the second base 84k can be substantially equal to the distance along the Z-axis between the second surface 601k of the foam structure 60k and the second base 84k of the second tensile member 74k. The first base 82k of the second tensile member 74k may include a substantially flat configuration. Therefore, the attachment portion 106k located between the second tensile member 74k (at the first base 82k) and the foam structure 60k can be formed such that substantially all of the first base 82k contacts the first surface 602k of the foam structure 60k. Additionally, the attachment portion 102k can cause substantially the entire first surface 601k of the foam structure 60k to contact the surface 53 of the first barrier layer 52.

[0155] The resulting structure includes a foam structure 60k and a second tensile member 74k housed within and surrounded by the first tensile member 72k. Furthermore, the first base 82k of the first tensile member 72k is substantially flush with the second surface 601k of the foam structure 60k, and the second base 84k of the first tensile member 72k is substantially flush with the second base 84k of the second tensile member 74k.

[0156] Reference Figures 14A to 14G Another footwear article 10m is shown. Except as otherwise provided herein, the structure and function of footwear article 10m may be substantially similar to those of footwear article 10. Given the substantial structural and functional similarity between the parts associated with footwear article 10m and those of footwear article 10, the same reference numerals are used hereinafter and in the accompanying drawings to identify the same parts, while the same reference numerals including letter extensions are used to identify those parts that have been modified.

[0157] Footwear product 10m may include an upper 20 and a sole structure 22m. The sole structure 22m may include a midsole 40m and an outsole 42. The midsole 40m may include a fluid-filled chamber 46m located within a cavity 47m of the body 44m. The fluid-filled chamber 46m may be as follows: Figures 2A to 2D As shown, the fluid filling chamber 46m can be located and oriented at any position within the footwear article 10m, and may include a first barrier layer 52m, a second barrier layer 54m, one or more foam structures 60m, and one or more tensile members 70m. The first barrier layer 52m and the second barrier layer 54m may define an anatomical shape such as the bottom of the foot. In this regard, the cavity 47m may also define an anatomical shape such as the bottom of the foot and dimensions corresponding to the dimensions of the fluid filling chamber 46m such that the fluid filling chamber 46m fits within the cavity 47m.

[0158] The first tensile member 72m of the tensile member 70m can be disposed relative to the Z-axis between the first barrier layer 52m and the second barrier layer 54m, such that: (i) the second base 84m of the first tensile member 72m engages the first surface 55m of the second barrier layer 54m at the fifth attachment portion 104m and (ii) the first base 82m engages the second surface 53m of the first barrier layer 52 at the second attachment portion 94m. The first base 82m and the second base 84m of the first tensile member 72m can include a substantially flat configuration. Therefore, the attachment portion 94m located between the tensile member 72m (at the first base 82m) and the first barrier layer 52m and the attachment portion 104m located between the tensile member 72m (at the second base 84m) and the second barrier layer 54m can be formed such that substantially all of the first base 82m and the second base 84m contact the first surface 55m and the second surface 53m, respectively.

[0159] The first tensile member 72m may include one or more channels 130m extending from the first substrate 82m and the second substrate 84m and extending along the Z-axis between the first substrate 82m and the second substrate 84m. In this regard, the first channel 130m1 may extend from a first opening 132m1 formed in the first substrate 82m to a second opening 134m1 formed in the second substrate 84m. The first opening 132m1 and / or the second opening 134m1 may be located within the heel end 12 of the first tensile member 72m, such that the tensile fiber 85m extends around the first channel 130m1 and partially defines the first channel 130m1. The second channel 130m2 may extend from the first opening 132m2 formed in the first substrate 82m to the second opening 134m2 formed in the second substrate 84m. The first opening 132m2 and / or the second opening 134m2 may be located within the center and / or intermediate portion of the first tensile member 72m, such that the tensile fiber 85m extends around and partially defines the second channel 130m2. In some configurations, the second channel 130m2 may be substantially aligned with the spherical portion of the wearer's foot. A third channel 130m3 may extend from the first opening 132m3 formed in the first base 82m to the second opening 134m3 formed in the second base 84m. The first opening 132m and / or the second opening 134m3 may be located within the forefoot end 14 of the first tensile member 72m, such that the tensile fiber 85m extends around and partially defines the third channel 130m3.

[0160] The second tensile member 74m of the tensile member 70m can be disposed within the first channel 130m1 and adjacent to the second barrier layer 54m, such that the second base 84m of the second tensile member 74m engages with the first surface 55m of the second barrier layer 54m at the fifth attachment portion 104m and is substantially flush with the second base 84m of the first tensile member 72m. The second base 84m of the second tensile member 74m may include a substantially flat configuration. Therefore, the attachment portion 104m located between the second tensile member 74m (at the second base 84m) and the second barrier layer 54m can be formed in such a manner that substantially all of the second base 84m of the second tensile member 74m contacts the first surface 55m of the second barrier layer 54m.

[0161] The third tensile member 76m of the tensile member 70m can be disposed within the second channel 130m2 and adjacent to the second barrier layer 54m, such that the second base 84m of the third tensile member 76m engages with the first surface 55m of the second barrier layer 54m at the fifth attachment portion 104m and is substantially flush with the second base 84m of the first tensile member 72m. The second base 84m of the third tensile member 76m can include a substantially flat configuration. Therefore, the attachment portion 104m located between the third tensile member 76m (at the second base 84m) and the second barrier layer 54m can be formed in such a way that substantially all of the second base 84m of the third tensile member 76m contacts the first surface 55m of the second barrier layer 54m.

[0162] The fourth tensile member 78m of the tensile member 70m can be disposed within the third channel 130m3 and adjacent to the second barrier layer 54m, such that the second base 84m of the fourth tensile member 78m engages with the first surface 55m of the second barrier layer 54m at the fifth attachment portion 104m and is substantially flush with the second base 84m of the first tensile member 72m. The second base 84m of the fourth tensile member 78m can include a substantially flat configuration. Therefore, the attachment portion 104m located between the fourth tensile member 78m (at the second base 84m) and the second barrier layer 54m can be formed in such a manner that substantially all of the second base 84m of the fourth tensile member 78m contacts the first surface 55m of the second barrier layer 54m.

[0163] The first foam structure 62m of the foam structure 60m can be disposed within the first channel 130ml and located between the first barrier layer 52m and the second tensile member 74m, such that (i) the second surface 601m of the first foam structure 62m joins the second surface 53m of the first barrier layer 52m at the fourth attachment portion 102m and is substantially flush with the first base 82m of the first tensile member 72m, and (ii) the first surface 602m of the first foam structure 62m joins the first base 82m of the second tensile member 74m at the sixth attachment portion 106m. Therefore, as Figure 14D and Figure 14G As illustrated, the distance along the Z-axis between the first base 82m of the first tensile member 72m and the second base 84m can be substantially equal to the distance along the Z-axis between the second surface 601m of the first foam structure 62m and the second base 84m of the second tensile member 74m. The first base 82m of the second tensile member 74m may include a substantially flat configuration. Therefore, the attachment portion 106m located between the second tensile member 74m (at the first base 82m) and the first foam structure 62m can be formed such that substantially all of the first base 82m contacts the first surface 602m of the first foam structure 62m. Furthermore, the attachment portion 102m can cause substantially the entire first surface 601m of the first foam structure 62m to contact the surface 53m of the first barrier layer 52m.

[0164] A second foam structure 64m of foam structure 60m can be disposed within the second channel 130m2 and located between the first barrier layer 52m and the third tensile member 76m, such that: (i) the second surface 601m of the second foam structure 64m joins the second surface 53m of the first barrier layer 52m at the fourth attachment portion 102m and is substantially flush with the first base 82m of the first tensile member 72m; and (ii) the first surface 602m of the second foam structure 64m joins the first base 82m of the third tensile member 76m at the sixth attachment portion 106m. Therefore, as Figure 14E and Figure 14G As illustrated, the distance along the Z-axis between the first base 82m of the first tensile member 72m and the second base 84m can be substantially equal to the distance along the Z-axis between the second surface 601m of the second foam structure 64m and the second base 84m of the third tensile member 76m. The first base 82m of the third tensile member 76m may include a substantially flat configuration. Therefore, the attachment portion 106m located between the third tensile member 76m (at the first base 82m) and the second foam structure 64m can be formed such that substantially all of the first base 82m contacts the first surface 602m of the second foam structure 64m. Furthermore, the attachment portion 102m allows substantially the entire first surface 601m of the second foam structure 64m to contact the surface 53m of the first barrier layer 52m.

[0165] The third foam structure 66m of the foam structure 60m can be disposed within the third channel 130m3 and located between the first barrier layer 52m and the fourth tensile member 78m, such that: (i) the second surface 601m of the third foam structure 66m joins the second surface 53m of the first barrier layer 52m at the fourth attachment portion 102m and is substantially flush with the first base 82m of the first tensile member 72m; and (ii) the first surface 602m of the third foam structure 66m joins the first base 82m of the fourth tensile member 78m at the sixth attachment portion 106m. Therefore, in Figure 14F and Figure 14G As illustrated, the distance along the Z-axis between the first base 82m of the first tensile member 72m and the second base 84m can be substantially equal to the distance along the Z-axis between the second surface 601m of the third foam structure 66m and the second base 84m of the fourth tensile member 78m. The first base 82m of the fourth tensile member 78m may include a substantially flat configuration. Therefore, the attachment portion 106m located between the fourth tensile member 78m (at the first base 82m) and the third foam structure 66m can be formed such that substantially all of the first base 82m contacts the first surface 602m of the third foam structure 66m. Furthermore, the attachment portion 102m can cause substantially the entire first surface 601m of the third foam structure 66m to contact the surface 53m of the first barrier layer 52m.
