Description

Technical Field

[0001] This invention relates to an upper for shoes, particularly athletic shoes, comprising a base layer and at least one reinforcing element. Specifically, the base layer comprises a unidirectional stretchable material that is stretchable in a first direction. Background Technology

[0002] Maximizing athlete performance is central to the development and evolution of sporting goods. This is especially true for athletic footwear, such as running shoes, where athlete performance critically depends on shoe performance. Therefore, numerous efforts have been made to optimize the performance of athletic footwear, particularly running shoes.

[0003] One of the key components of athletic shoes, especially running shoes, is the upper, as it allows the shoe to hold the athlete's foot in place during walking and / or running. Furthermore, to provide optimal comfort and support to the athlete, the upper should be configured to fit and / or adapt to the athlete's foot.

[0004] One approach to designing shoe uppers involves using a one-piece upper, for example, an upper with seams only in the heel area, where the one-piece upper is non-stretchable. Using such a one-piece upper has proven to simplify shoe production. Furthermore, this one-piece upper reduces the number of seams required, which is advantageous because seams in the upper can cause irritation to the wearer's foot. Typically, if a one-piece upper is used, its non-stretchability is required to ensure the upper remains taut against the foot during athletic activity. However, by using a non-stretchable upper, the upper cannot conform to the complex shape of the last and / or the foot. Therefore, a non-stretchable upper cannot achieve the desired fit of the shoe, thus reducing wearing comfort and athlete performance.

[0005] Complementary approaches to designing one-piece uppers include the use of stretchable materials. However, by using stretchable materials, the upper cannot properly hold and / or support the athlete's foot during walking and / or running. This loss of stability necessitates large and / or perhaps multiple reinforcing elements to achieve the desired stability. These reinforcing elements are rigid and heavy, thus offsetting the stretchable material's ability to conform to the complex shape of the last and / or foot. Consequently, the added weight and rigidity of the upper reduce the athlete's wearing comfort and performance.

[0006] In this context, US 9,826,799 B2 describes a composite shell for a footwear upper, comprising a base layer and a fiber reinforcement layer. The base layer may comprise a mesh or other type of fabric material and may extend at least on the sides of an internal region of the foot-shaped upper. The fiber reinforcement layer may be at least partially bonded to the base layer. The fiber reinforcement layer may extend at least from the lower portion of the base layer (which generally corresponds to the periphery of the footbed) to at least the upper portion of the base layer (which generally corresponds to a portion of the instep region). The fiber reinforcement layer may include a plurality of strips extending from the lower to the upper portion, these strips being separated by gaps between the strips in the fiber reinforcement layer.

[0007] Therefore, there is a need for an improved upper for shoes, especially athletic shoes, that addresses at least some of the aforementioned shortcomings of the prior art and further improves other aspects. Summary of the Invention

[0008] A first aspect of the invention relates to a shoe upper, particularly an upper for athletic shoes. The upper includes a base layer comprising a unidirectional stretchable material, wherein the unidirectional stretchable material is stretchable in a first direction. The upper also includes at least one reinforcing element, wherein the reinforcing element is arranged to restrict the stretchability of the unidirectional stretchable material at least in the first direction.

[0009] A one-way stretchable material is stretchable in a first direction. For example, the term one-way may refer to the first direction. Typically, the first direction may include the direction relative to the planar state of the upper. The planar state of the upper may include: the upper is not included in the shoe, for example, the upper is not attached to the midsole of the shoe. For example, the planar state of the upper may include: the upper is unfolded and flat.

[0010] The base layer comprising a unidirectional stretchable material may include a unidirectional stretchable material substantially throughout its entire extent. For example, the unidirectional stretchable material may be uniformly distributed throughout the base layer. For example, at least 60%, preferably at least 70%, more preferably at least 80%, even more preferably at least 90%, and most preferably at least 95% of the base layer and / or the upper may include a unidirectional stretchable material.

[0011] The upper also includes at least one reinforcing element. The at least one reinforcing element may include connected reinforcing elements. Additionally, or alternatively, the reinforcing element may include at least two non-connected reinforcing elements. The at least one reinforcing element may be arranged to restrict the stretchability of the unidirectional stretchable material at least in a first direction. In particular, the at least one reinforcing element may be arranged to locally restrict the stretchability of the unidirectional stretchable material. For example, the at least one reinforcing element may restrict the stretchability of the unidirectional stretchable material in at least one region of the base layer. In particular, at least one region of the base layer may be associated with the position of the at least one reinforcing element relative to the base layer. For example, a first reinforcing element may be arranged at a first position to restrict the stretchability of the base layer in a first region associated with the first position. Restricting the stretchability of the unidirectional stretchable material at least in a first direction may include: reducing the stretchability of the unidirectional stretchable material at least in a first direction.

[0012] An upper comprising a unidirectional stretchable material and at least one reinforcing element (arranged to limit the stretchability of the upper in at least a first direction) allows for control over the stretchability of the upper in at least a first direction. For example, controlling stretchability in at least a first direction allows for adjustment of stretchability toward a target stretchability, and / or allows for adjustment of stretchability according to the athlete's needs. Furthermore, controlling stretchability in at least a first direction allows the fabric of the upper (e.g., the base layer) to adapt to extreme and / or unusual shapes of the last, such as lasts including areas with high curvature. For example, a last including extreme and / or unusual shapes may include protruding volume areas and / or curved sculpted areas and / or at least one transition area that changes from convex to concave (or vice versa). Therefore, using an upper comprising a unidirectional stretchable material and at least one reinforcing element (arranged to limit the stretchability of the upper in at least a first direction) enables the production of perfectly fitting uppers using a one-piece base layer and / or a one-piece upper—even when the last has unusual shapes. In particular, using a one-piece upper reduces the number of production steps and further reduces the weight of the final shoe (e.g., the shoe including the upper). Therefore, the upper described above improves production efficiency and contributes to a minimum shoe weight. This minimum shoe weight further helps optimize the performance of the athlete wearing the shoe.

[0013] Typically, unidirectional stretchable materials can include materials that are substantially stretchable only in a first direction. In particular, being substantially stretchable only in the first direction can include materials that are substantially non-stretchable in a second direction. For example, the second direction may be perpendicular to the first direction.

[0014] For example, the term unidirectional can refer to a material that is stretchable essentially only in one direction and specifically in a first direction. In other words, a unidirectional stretchable material may be stretchable only in the first direction. For example, a unidirectional stretchable material may not be stretchable in a second direction perpendicular to the first direction. In particular, a unidirectional stretchable material may be taut in the second direction. Specifically, not being stretchable in the second direction may include: the stretchability of the material in the second direction being much smaller compared to its stretchability in the first direction.

[0015] Typically, the stretchability of materials and / or fabrics is assessed based on tensile testing under load. For example, applying tension to the base layer in a first direction stretches the base layer by a first amount, and applying tension of the same magnitude as the first force in a second direction stretches the base layer by a second amount. For example, the magnitude of the force can be in the range of 10 N to 300 N, preferably in the range of 20 N to 200 N, and most preferably in the range of 25 N to 100 N. In particular, the first amount can be greater than the second amount, for example, by a factor of at least 1.2, preferably at least 1.4, more preferably at least 1.6, even more preferably at least 1.8, and most preferably at least 2. In particular, the ratio (multiple) between the first amount and the second amount can depend at least in part on the magnitude of the applied force, for example, the magnitude of the first force. For example, this ratio (multiple) can depend non-linearly on the applied force. Typically, the second direction can be perpendicular to the first direction. The second direction can include a direction relative to the planar state of the shoe upper.

[0016] Using a unidirectional stretchable material that is essentially stretchable only in a first direction allows for precise adjustment of stretchability in that first direction. Specifically, being essentially stretchable only in the first direction ensures that limiting the stretchability of the base layer and / or upper in only that first direction is sufficient; for example, additional reinforcing elements suitable for limiting stretchability in a second direction are unnecessary. This ensures a good fit between the upper and / or the shoe including it. A good fit between the upper and / or the shoe enhances wearing comfort and thus optimizes athlete performance. Furthermore, using a unidirectional stretchable material that is essentially stretchable only in the first direction ensures that the upper is sufficiently stable to support the athlete's foot (especially during walking and / or running) while being stretchable in selected areas to accommodate the shape of the last and the foot.

[0017] Specifically, the second direction may include a component parallel to the direction extending from the lateral side of the upper to the mesial side of the upper. For example, the second direction may be substantially parallel to the direction extending from the lateral side to the mesial side.

[0018] For example, when the upper is attached to the sole of the shoe, the lateral side and / or mid-side of the upper may refer to the corresponding side of the shoe. For example, when the upper may include a substantially two-dimensional extension, the direction extending from the lateral side to the mid-side of the upper may include a direction relative to the planar state of the upper. For example, a second direction, such as the direction in which the material is substantially non-stretchable, may include a component parallel to the direction extending from the lateral side to the mid-side of the upper. In particular, including a component parallel to the direction extending from the lateral side to the mid-side of the upper may include: the angle between the second direction and the direction extending from the lateral side to the mid-side of the upper is less than 90°, preferably less than 75°, more preferably less than 60°, even more preferably less than 45°, and most preferably less than 30°. In some embodiments, the second direction may be substantially parallel to the direction extending from the lateral side to the mid-side. For example, the second direction and the direction extending from the side of the body to the mesial side may be substantially the same direction. For example, the angle between the second direction and the direction extending from the side of the body to the mesial side may be less than 20°, preferably less than 15°, more preferably less than 10°, even more preferably less than 6°, and most preferably less than 3°.

[0019] Typically, the first direction may include a component parallel to the longitudinal direction of the shoe and / or the upper. For example, the first direction may be substantially parallel to the longitudinal direction.

[0020] The longitudinal direction of the upper and / or shoe may include a direction extending from the area of ​​the upper and / or shoe associated with the heel to the area of ​​the upper and / or shoe associated with the forefoot and / or toes. For example, the area of ​​the shoe associated with the heel may include an area adapted to accommodate the wearer's heel and / or rearfoot. Furthermore, the area associated with the forefoot and / or toes may include an area adapted to accommodate the wearer's forefoot and / or toes.

[0021] Specifically, the component parallel to the longitudinal direction of the upper and / or the shoe may include: an angle between the first direction and the longitudinal direction of the upper and / or the shoe is less than 90°, preferably less than 75°, more preferably less than 60°, even more preferably less than 45°, and most preferably less than 30°. In some embodiments, the first direction may be substantially parallel to the longitudinal direction of the upper and / or the shoe. For example, the first direction and the longitudinal direction of the upper and / or the shoe may include substantially the same direction; for example, the angle between the first direction and the longitudinal direction of the upper and / or the shoe may be less than 20°, preferably less than 15°, more preferably less than 10°, even more preferably less than 6°, and most preferably less than 2°. In some embodiments, the first direction may include a component parallel to the last ridge line; for example, the first direction may at least partially follow the last ridge line.

[0022] Stretchability of the material in a direction including a component parallel to the longitudinal direction of the upper and / or the shoe enhances the adaptability of the upper to the last and / or the shoe. For example, stretchability in a direction including a component parallel to the longitudinal direction of the upper and / or the shoe allows the upper to adapt to the last and / or the shoe, even when the last includes extreme and / or unusual shapes. Therefore, stretchability of the material in a direction including a component parallel to the longitudinal direction of the upper and / or the shoe makes it possible to use a one-piece upper, for example, an upper and / or base layer formed essentially from a single piece.

[0023] Furthermore, the first direction, including a component parallel to the ridge line of the last, allows the material to extend along the ridge line of the last, thereby accommodating the raised portion of the last while still attaching to the adjacent recessed portion of the last, such as the recessed portion corresponding to the arch of the foot.

[0024] Typically, at least one reinforcing element may be arranged such that at least one reinforcing element extends at least partially into the first direction.

[0025] For example, extending at least partially in the first direction may include at least one reinforcing element having a dimension in the first direction, for example, including a component extending in the first direction. Furthermore, extending at least partially in the first direction may include at least one reinforcing element also including a dimension and / or extension in a second direction. Typically, at least one reinforcing element may include a dimension and / or extension in both the first and second directions. For example, extending at least partially in the first direction may include a dimension and / or extension in the first direction that is larger than a dimension and / or extension in the second direction. In particular, including a dimension and / or extension in the first direction that is larger than a dimension and / or extension in the second direction may include at least one reinforcing element whose projection in the first direction is larger than its projection in the second direction.

[0026] A reinforcing element arranged to extend at least partially in the first direction ensures that the stretchability of the unidirectional stretchable material is confined to selected and / or target areas, such as selected and / or target portions of the upper. Specifically, the reinforcing element extending at least partially in the first direction allows for the restriction of the stretchability of the unidirectional stretchable material—in terms of the size and / or extent of extension of the reinforcing element in the first direction. Therefore, the reinforcing element arranged to extend at least partially in the first direction allows for precise and focused control of the stretchability of the unidirectional stretchable material, and thus helps optimize the adaptation of the upper and / or base layer to the shape of the last, for example, to lasts including unusual and / or extreme shapes, and therefore to the athlete's foot.

[0027] At least one reinforcing element may be arranged at the surface of the substrate layer. For example, at least one reinforcing element may be arranged at the inner surface of the substrate layer.

[0028] The base layer may include two surfaces, for example, an inward-pointing surface and an outward-pointing surface. Specifically, for example, when the upper is in a flat state, the inward-pointing surface may include a surface opposite to the outward-pointing surface. For example, the inward-pointing surface may include a surface adapted to point inwards towards the inside of the shoe, i.e., for example, when arranged on the shoe, pointing towards the gap for accommodating the wearer's foot. In particular, the inward-pointing surface may be adapted to directly or indirectly contact the athlete's foot. Furthermore, the outward-pointing surface may include the outer surface of the shoe.

[0029] Positioning a reinforcing element at the surface of the substrate (e.g., at the inner surface of the substrate) may include: the reinforcing element being at least partially fixed to and / or at least partially in contact with the surface of the substrate. For example, the reinforcing element may be placed on the surface of the substrate.

[0030] Additionally, or alternatively, the reinforcing element may be disposed on the outer surface of the base layer. For example, the entire reinforcing element may be disposed on the outer surface of the base layer, or the reinforcing element may be disposed only on the outer surface. Typically, the reinforcing element may be disposed on both the inner and outer surfaces. For example, a first portion of the reinforcing element may be disposed on the inner surface, and a second portion may be disposed on the outer surface. In some embodiments, at least a portion of the reinforcing element may be disposed within the base layer. For example, at least a portion of the reinforcing element may be disposed between the inner and outer surfaces of the base layer. In particular, the base layer may include at least one pocket—adapted to receive at least a portion of the reinforcing element.

[0031] Positioning the reinforcing elements on the surface of the base layer simplifies and / or optimizes the process of placing the reinforcing elements on the upper. Therefore, the number of required production steps can be minimized, which accelerates upper production. Accelerated upper production contributes to optimized production and maximized efficiency.

[0032] In particular, positioning at least one reinforcing element on the outer surface makes the inner surface of the shoe upper smoother, thereby minimizing discontinuities on the inner surface and thus making the shoe more comfortable.

[0033] In addition, positioning at least one reinforcing element on the inner surface helps to make the outer surface of the base material and / or the upper smoother and cleaner, thereby optimizing the athlete's control of the ball when kicking, for example, in a sport such as football.

[0034] Typically, at least one reinforcing element may be arranged such that at least a portion of the reinforcing element is thermally bonded to the base layer. Additionally, or alternatively, at least one reinforcing element may be arranged such that at least a portion of the reinforcing element is sewn to the base layer. Additionally, or alternatively, at least one reinforcing element may be arranged such that at least a portion of the reinforcing element is glued and / or bonded and / or taped to the base layer. Additionally, or alternatively, at least one reinforcing element may be arranged such that at least a portion of the reinforcing element is secured to the base layer by molten yarn, for example, the molten yarn is incorporated into the base layer and / or the reinforcing element. Specifically, the molten yarn may be incorporated into the base material and / or the material of at least one reinforcing strip.

[0035] Additionally, or alternatively, at least a portion of the reinforcing element may be embroidered to the base layer. For example, the (entire) reinforcing element may be embroidered to the base layer. In particular, at least a portion of the reinforcing element may be embroidered to the base layer at least partially based on the strong thread and / or heat-fused yarn and subsequent heat pressing.

[0036] For example, at least a portion of the reinforcing element may be thermally bonded to a portion of the surface of the base layer. For example, at least a portion of the reinforcing element may be thermally bonded to a portion of the inner and / or outer surface of the base layer. Additionally, or alternatively, at least a portion of the reinforcing element may be sewn to the base layer. For example, at least a portion of the reinforcing element may be sewn to the surface of the base layer, such as the inner and / or outer surface. In some embodiments, a first portion of the reinforcing element may be thermally bonded to the base layer, and a second portion of the reinforcing element may be sewn to the base layer.

[0037] Thermally bonding and / or sewing at least a portion of the reinforcing element to the base layer ensures that the reinforcing element is adequately secured to the base layer without substantially altering it. Furthermore, thermally bonding and / or sewing at least a portion of the reinforcing element to the base layer accelerates the attachment process, thereby making the production of the upper and / or shoe more efficient.

[0038] At least one reinforcing element may be arranged substantially symmetrically with respect to the mid-shoe and side portions of the upper.

[0039] Typically, the reinforcement elements that are substantially symmetrical with respect to the midfoot and lateral portions of the upper may have the same characteristics as those associated with the midfoot and lateral portions. For example, the number of reinforcement strips associated with the midfoot portion of the upper may be the same as the number of reinforcement strips associated with the lateral portions of the upper. In other words, the midfoot portion of the upper may include the same number of reinforcement strips as the lateral portions. Furthermore, the reinforcement strips on the midfoot portion of the upper may include the same width as the reinforcement strips on the lateral portions.

[0040] Additionally, or alternatively, substantially symmetrical about the mid-section and lateral sections of the upper may include: the portion of the reinforcing element associated with the mid-section of the upper substantially matching the portion of the reinforcing element associated with the lateral section of the upper. For example, matching may include: the mid-section of the reinforcing element having the same shape and size.

[0041] Additionally, or alternatively, substantially symmetrical with respect to the mid-section and lateral sections of the upper may include: the portion of the reinforcing element associated with the mid-section of the upper is substantially similar to the portion of the reinforcing element associated with the lateral section of the upper. For example, similarity may include: the mid-section of the reinforcing element comprising the same shape. Specifically, similarity may exclude characteristics such as the position, scale, orientation, and / or reflection of portions of the reinforcing element. For example, the mid-section of the reinforcing element may be considered similar when the lateral section of the reinforcing element corresponds to the mid-section of the reinforcing element up to a certain scale.

[0042] For example, the upper can be configured such that the midfoot portion and the lateral portion of the upper substantially define an axis of symmetry. A symmetrical arrangement relative to the midfoot and lateral portions of the upper may include at least one reinforcing element that is symmetrical about the axis of symmetry. For example, the axis of symmetry of at least one reinforcing element may substantially coincide with the axis of symmetry of the upper, wherein the axis of symmetry of the upper extends in the longitudinal direction. For example, when at least one reinforcing element comprises only one reinforcing element, the symmetrical arrangement may include: the reinforcing element is symmetrical, and the axis of symmetry of the reinforcing element may coincide with the axis of symmetry of the upper. Additionally, or alternatively, when at least one reinforcing element comprises at least two elements, the symmetrical arrangement may include: at least two reinforcing elements arranged symmetrically about the axis of symmetry of the upper. For example, the number and / or arrangement of reinforcing elements associated with the midfoot side of the upper may correspond to the number and / or arrangement of reinforcing elements associated with the lateral side of the upper.

[0043] Additionally, or alternatively, the substantially symmetrical arrangement of the upper with respect to the midfoot and lateral portions may include at least one subgroup of bands associated with the midfoot side of the upper and at least one subgroup of bands associated with the lateral side of the upper. For example, a first lateral reinforcement band disposed at the lateral portion of the upper and a first midfoot reinforcement band disposed at the midfoot portion of the upper may be substantially symmetrical. Specifically, the first lateral reinforcement band and the first midfoot reinforcement band may each include a reinforcement band extending from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the heel region. Additionally, or alternatively, the upper may include a second lateral reinforcement band and / or a second midfoot reinforcement band, for example, the number of second reinforcement bands in the midfoot and lateral portions may be different. For example, the upper may include a second lateral reinforcement band and a second midfoot reinforcement band. In particular, the second lateral reinforcement band may include a different shape and / or size and / or orientation than the second midfoot reinforcement band.

[0044] Arranging at least one reinforcing element substantially symmetrically with respect to the midfoot and lateral portions of the upper ensures that the stretchability of the unidirectional stretchable material in the midfoot region is substantially the same as that in the lateral portion. Therefore, the stretchability of the upper can be substantially symmetrical with respect to the midfoot and lateral portions. This symmetrical stretchability of the upper helps optimize its adaptation to the last (e.g., a last with extreme and / or unusual shapes) and also helps optimize its adaptation to the athlete's foot.

[0045] In some embodiments, at least one reinforcing element may surround at least a portion of the eyelets of the upper. For example, at least one reinforcing element may surround all of the eyelets of the upper.

[0046] The material associated with at least one reinforcing element may at least partially surround at least a portion of the eyelets of the upper. For example, at least one reinforcing element may surround at least two adjacent eyelets of the upper. Additionally, or alternatively, the reinforcing element may surround non-adjacent eyelets of the upper; for example, between two eyelets encompassed and / or enclosed by the upper, at least one eyelet may exist that is not encompassed and / or enclosed by the reinforcing element.

[0047] Typically, at least one reinforcing element may surround at least a portion of the eyelets so as to symmetrically surround the eyelets with respect to the axis of symmetry of the upper. For example, the mid-section of the eyelet may be located on the mid-side of the upper, and the lateral portion of the eyelet may be located on the lateral side of the upper. In particular, at least one reinforcing element may be arranged to surround the same number of lateral and mid-section eyelets. In particular, at least one reinforcing element may include at least two, preferably at least three, more preferably at least four, and most preferably at least five eyelets in the mid-section and / or lateral eyelets. In particular, at least one reinforcing element may surround all the eyelets of the upper, for example, all the mid-section eyelets and all the lateral eyelets of the upper.

[0048] Additionally, or alternatively, the eyelets may be spaced apart from each other. For example, the first eyelet may be separated from the second eyelet by a first gap. Specifically, at least one reinforcing element may surround the eyelet to extend between the gaps of adjacent eyelets. For example, at least one reinforcing element may surround the first and second eyelets to cover the first gap. For example, at least a portion of the gap may include a portion of the reinforcing element.

[0049] Arranging at least one reinforcing element to surround at least a portion of the eyelet of the upper allows for limiting the stretchability of the unidirectional stretchable material, at least in a first direction. For example, the eyelet may be arranged substantially along the longitudinal direction of the upper and / or the shoe. In particular, arranging at least one reinforcing element to surround at least a portion of the eyelet of the upper enhances the stability of the upper in the area associated with the eyelet, thereby contributing to improved foot support and lockdown.

[0050] The reinforcing element surrounding at least a portion of the eyelets on the upper can also serve as a reinforcing element to prevent wear and tear of the base material / layer around the eyelets—due to tension applied by the laces. In other words, the reinforcing element surrounding at least a portion of the eyelets on the upper may (primarily) be directed to reinforce the material around the eyelets and may (only secondarily) be directed to limit the stretchability of the unidirectional stretchable material. In particular, adapting the reinforcing element to surround at least a portion of the eyelets may be an optional feature, for example, it may be omitted, with respect to limiting the stretchability of the unidirectional stretchable material.

[0051] Specifically, at least one reinforcing element may surround the eyelet as a substantially continuous segment surrounding the eyelet.

[0052] For example, at least one reinforcing element may surround a continuous set of eyelets. Specifically, at least one reinforcing element may surround the first eyelet and the last eyelet, and all eyelets in between. Surrounding the eyelets as a substantially continuous segment may include: at least one reinforcing element extending between the first eyelet and the last eyelet. For example, at least one reinforcing element may extend substantially continuously between the first eyelet and the last eyelet. Specifically, extending substantially continuously between the first eyelet and the last eyelet may include: extending between the first eyelet and the last eyelet without gaps, where a gap refers to, for example, a portion not surrounded by at least one reinforcing element.

[0053] Arranging at least one reinforcing element as a substantially continuous segment surrounding the eyelet allows for limiting the stretchability of the unidirectional stretchable material at least in a first direction. In particular, arranging at least one reinforcing element as a substantially continuous segment surrounding the eyelet enhances the stability of the upper in the area associated with the eyelet, thereby contributing to improved foot support and lockdown.

[0054] Typically, at least one reinforcing element may include at least one reinforcing band. Specifically, at least one reinforcing band may extend from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the midsole and / or the heel counter. Additionally, or alternatively, at least one reinforcing band may extend from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the heel area.

[0055] The reinforcing strip may include at least a portion of the reinforcing element such that the extension of the reinforcing strip in the first direction is greater than the extension of the reinforcing strip in the second direction. For example, the reinforcing strip may include a substantially rectangular shape, such as one part extending primarily in the first direction and one part extending secondaryly in the second direction. Specifically, the reinforcing strip may include a strip shape.

[0056] Additionally, or alternatively, at least one reinforcing strip may extend from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the midsole and / or the PVC strip. The area of ​​the upper associated with the midsole and / or the PVC strip may include areas of the upper adapted to contact the midsole and / or the PVC strip.

[0057] Specifically, when the shoe is suitable for sports involving multi-directional movement and / or high speed, such as (large) lateral movements, such as sprinting, soccer, basketball, baseball, and / or tennis, the upper may include a reinforcing band extending from the area associated with the eyelets toward the area associated with the midsole and / or the bushing. Additionally, or alternatively, when the base material is very lightweight, the upper may include a reinforcing band extending from the area associated with the eyelets toward the area associated with the midsole and / or the bushing.

[0058] Additionally, or alternatively, the area of ​​the upper associated with the midsole and / or strut may include areas of the upper suitable for (e.g., by gluing) securing to the midsole and / or strut. For example, reinforcing strips may extend beyond the interlocking line and / or the top processing line, such as the upper edge of the midsole.

[0059] For example, the reinforcement strip may begin in the area of ​​the upper associated with the eyelets and may terminate in the area associated with the midsole and / or the stylist. In particular, the reinforcement strip may be configured such that the direction (main direction) associated with the greater extension of the reinforcement strip may include a component parallel to the direction from the area of ​​the upper associated with the eyelets to the area associated with the midsole and / or the stylist.

[0060] Additionally, or alternatively, at least one reinforcing strip may extend from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the heel region. For example, the reinforcing strip may begin in the area of ​​the upper associated with the eyelet and may terminate in the area associated with the heel region. For example, the reinforcing strip may terminate in the area associated with the rear edge of the heel portion (e.g., the rear seam of the heel portion). Specifically, the reinforcing strip may begin in the eyelet region on the forefoot, for example, the first and / or second lacing eyelets on the forefoot region of the upper. In particular, the reinforcing strip may be configured such that the direction (primary direction) associated with the greater extension of the reinforcing strip may include a component parallel to the direction—from the area of ​​the upper associated with the eyelet to the area associated with the heel region.

[0061] A reinforcing element including at least one reinforcing band allows for efficient and effective use of the reinforcing element, for example, hardening a large portion of the base layer while using only a minimal portion of the reinforcing element. Specifically, the reinforcing band may include a primary dimension and / or extension in a direction substantially parallel to a first direction (i.e., the direction in which a unidirectional stretchable material can be stretched), and a secondary dimension and / or extension in a second direction (i.e., the direction in which a unidirectional material cannot be stretched). Therefore, using a reinforcing band minimizes the portion of the base layer including the reinforcing band, and / or minimizes the amount of reinforcing band necessary to achieve the desired hardening and / or stretchability limits. Minimizing the amount of reinforcing band necessary to achieve the desired hardening and stretchability limits minimizes the weight of the upper and / or the shoe. Minimizing the weight of the upper and / or the shoe can contribute to improved athlete performance and can further reduce production costs, for example, by reducing the amount of necessary material and / or accelerating production.

[0062] Specifically, a reinforcing element comprising at least one reinforcing band extends from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the heel region, allowing for the creation of a tension line from the forefoot to the heel region. Therefore, at least one reinforcing element provides sufficient support and lockdown for the foot, which is necessary for any sport, and particularly for sports involving linear movement (e.g., marathon running), it will be sufficient. Specifically, for linear movement, such as running, the extension of at least one reinforcing band from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the heel region may be sufficient; for example, a reinforcing band extending from the area of ​​the upper associated with the eyelet to the area of ​​the upper associated with the midsole and / or strut may not be necessary to ensure adequate foot support.

[0063] Typically, at least one reinforcing strip may begin in the area below the eyelet on the upper, for example, there may be a distance between the eyelet on the upper and at least one reinforcing strip.

[0064] Additionally, or alternatively, at least one reinforcing band may extend from a substantially continuous segment that surrounds the eyelet of the upper.

[0065] For example, at least one reinforcing strip may originate from a substantially continuous segment surrounding the eyelets of the upper. For example, at least one reinforcing strip may originate from a substantially continuous segment surrounding the eyelets of the upper and extend toward the area associated with the midsole and / or the heel counter. Additionally, or alternatively, at least one reinforcing strip may originate from a substantially continuous segment surrounding the eyelets of the upper and extend toward the area associated with the heel region. In some embodiments, the upper may include: a first reinforcing strip extending from a substantially continuous segment toward the area associated with the midsole and / or the heel counter, and a second reinforcing strip extending from a substantially continuous segment toward the area associated with the heel region. Specifically, the upper may include first and second reinforcing strips on the mid-side and lateral side of the midsole; for example, the upper may include four reinforcing strips. In particular, the reinforcing strips may be arranged symmetrically with respect to the mid-side and lateral side of the upper.

[0066] The reinforcing strip extending from a substantially continuous segment surrounding the eyelet of the upper allows for localized and efficient hardening of the base layer and / or the upper, at least in a first direction. Furthermore, since the reinforcing elements can comprise continuous reinforcing elements, such as substantially continuous segments from which the reinforcing strip extends, the arrangement of the reinforcing elements at the base layer (e.g., at the surface of the base layer) can be simplified. Simplifying the arrangement of the reinforcing elements at the base layer can accelerate and / or optimize the production of the upper.

[0067] Typically, the upper may include at least one reinforcing band. Additionally, or alternatively, the upper may include at least two reinforcing bands. Additionally, or alternatively, the upper may include at least three reinforcing bands. Additionally, or alternatively, the upper may include at least four reinforcing bands. In some embodiments, the upper may include up to 20 reinforcing bands. Additionally, or alternatively, the upper may include up to 16 reinforcing bands. Additionally, or alternatively, the upper may include up to 12 reinforcing bands. Additionally, or alternatively, the upper may include up to 8 reinforcing bands. Additionally, or alternatively, the upper may include up to 6 reinforcing bands.

[0068] For example, the upper may include at least two reinforcing bands, such as a first reinforcing band on the mesial side of the base layer and a second reinforcing band on the lateral side of the base layer. Additionally, or alternatively, the upper may include at least two reinforcing bands on each side, such as two reinforcing bands on the mesial side and two reinforcing bands on the lateral side. Additionally, or alternatively, the upper may include up to 20 reinforcing bands. For example, the upper may include a total of up to 20 reinforcing bands, for example, the sum of the reinforcing bands on the mesial side and the reinforcing bands on the lateral side may be up to 20. In some embodiments, the number of reinforcing bands on the mesial side and / or the lateral side may be up to 20.

[0069] An upper comprising at least two reinforcing bands and / or up to 20 reinforcing bands ensures adequate restriction of the stretchability of the base layer and / or upper, at least in a first direction, while guaranteeing efficient use of reinforcing elements, for example, achieving the desired restriction and / or hardening with a minimum number of reinforcing bands.

[0070] Typically, the width of at least one reinforcing strip may be at least 0.25 cm. Alternatively, the width of at least one reinforcing strip may be at least 0.5 cm. Alternatively, the width of at least one reinforcing strip may be at least 0.75 cm. Alternatively, the width of at least one reinforcing strip may be at least 1 cm. Alternatively, the width of at least one reinforcing strip may be at least 1.25 cm. Alternatively, the width of at least one reinforcing strip may be at most 3 cm, preferably at most 2.75 cm, more preferably at most 2.5 cm, even more preferably at most 2.25 cm, and most preferably at most 2 cm.

[0071] The width of at least one reinforcing band may include the extension of the reinforcing band in the direction associated with a smaller extension (e.g., a secondary extension of the reinforcing band). Including a reinforcing band at least 0.25 cm wide can help limit the stretchability of the unidirectional stretchable material, at least in a first direction. Specifically, including a reinforcing band at least 0.25 cm wide ensures the achievement of the desired limitation on stretchability and / or the desired stiffening of the upper. Therefore, using a reinforcing band at least 0.25 cm wide can enhance foot support and / or lockdown.

[0072] Typically, at least one reinforcing element may comprise a non-stretchable material. For example, at least one reinforcing element may comprise artificial suede and / or non-stretchable fabric and / or leather and / or polymer-based straps.

[0073] Non-stretchable materials may include materials whose stretchability is less than that of a unidirectional stretchable substrate. For example, non-stretchable materials may include materials that are not stretchable in all directions, such as a first direction and a second direction, which are substantially perpendicular. For example, non-stretchable materials may include substantially taut materials. Specifically, non-stretchable materials may be configured such that they can be thermally bonded and / or sewn to a substrate layer. Specifically, reinforcing elements may comprise artificial suede. Additionally, or alternatively, non-stretchable materials may include non-stretchable fabrics. Additionally, or alternatively, non-stretchable materials may include leather, natural or synthetic materials. Additionally, or alternatively, non-stretchable materials may include polymer-based straps. For example, polymer-based straps may comprise polyurethane.

[0074] Using reinforcing elements containing non-stretchable material ensures that the reinforcing element restricts the stretchability of the unidirectional stretchable material at least in a first direction. Therefore, reinforcing elements containing non-stretchable material help harden at least a portion of the base layer and / or upper. The rigid portion of the base layer and / or upper maximizes foot support and / or foot locking.

[0075] In some embodiments, the base layer may comprise a woven material, which includes weft and warp yarns. Specifically, the weft may comprise at least one weft yarn, and the warp may comprise at least one warp yarn. For example, the at least one weft yarn and the at least one warp yarn may be configured such that the at least one weft yarn is more stretchable than the at least one warp yarn. Additionally, or alternatively, the at least one weft yarn and the at least one warp yarn may be configured such that the at least one warp yarn is more stretchable than the at least one weft yarn.

[0076] Specifically, in a preferred embodiment, at least one weft yarn may be more stretchable than at least one warp yarn, because adjusting at least one warp yarn may be more difficult and thus hinder production.

[0077] For example, the base layer may substantially comprise a woven material. The woven material may comprise at least one weft yarn and / or at least one warp yarn. Typically, the at least one weft yarn and at least one warp yarn of the woven material may be arranged to cross each other substantially at right angles. For example, the at least one weft yarn may be more stretchable than the at least one warp yarn. In particular, all weft yarns may be more stretchable than the warp yarns. Specifically, all weft yarns may include a first stretchability, and all warp yarns may include a second stretchability. For example, the first stretchability may be greater than the second stretchability; for example, the weft yarns may be more stretchable than the warp yarns. In other words, all weft yarns may substantially comprise the same stretchability, and all warp yarns may substantially comprise the same stretchability. For example, the warp yarns may be substantially non-stretchable. In particular, the weft yarns may be stretchable, and the warp yarns may be non-stretchable. Specifically, the weft yarns may extend in a first direction and / or the warp yarns may extend in a second direction. For example, the weft yarns may extend in the first direction, while the warp yarns may extend in the second direction, in order to at least partially define a unidirectional stretchable material.

[0078] For example, more stretchable yarns, such as weft yarns, may include high-stretch yarns, particularly high-crib yarns. For instance, high-crib yarns may include textured yarns that have been processed to have a high degree of crimp. Additionally, or alternatively, high-stretch yarns may include side-by-side yarns.

[0079] In some embodiments, differential stretching in woven materials can be achieved by placing an elastic thread every few weft yarns.

[0080] Additionally, or alternatively, at least one warp yarn may be more stretchable than at least one weft yarn. In particular, all warp yarns may be more stretchable than weft yarns. Specifically, all warp yarns may possess a first stretchability, and all weft yarns may possess a second stretchability. For example, the first stretchability may be greater than the second stretchability; for instance, the warp yarns may be more stretchable than the weft yarns.

[0081] In some embodiments, the weft yarns may include different stretchability. For example, a first weft yarn may include a first stretchability, and a second weft yarn may include a second stretchability. Additionally, or alternatively, the warp yarns may include different stretchability. For example, a first warp yarn may include a first stretchability, and a second warp yarn may include a second stretchability. Specifically, the stretchability of the weft and / or warp yarns may be such that the effective stretchability of the weft yarn (e.g., the stretchability associated with the weft) is greater than the effective stretchability of the warp yarn (e.g., the stretchability associated with the warp).

[0082] Woven fabrics comprising weft and warp yarns with varying stretchability can contribute to unidirectional stretchable materials. Specifically, the weft and / or warp yarns can at least partially define a first and second direction of the unidirectional stretchable material, e.g., a stretchable direction and a non-stretchable direction. Therefore, woven fabrics comprising weft and warp yarns with varying stretchability contribute to the fit of the upper to the foot and / or the last (e.g., including unusually shaped lasts). In particular, woven fabrics can contribute to an optimal fit between the upper and / or the shoe and the athlete's foot, thereby maximizing wearing comfort and thus optimizing performance.

[0083] Additionally, or alternatively, the base layer may include a knitted material.

[0084] For example, a portion of the base layer may include a knitted material. In some embodiments, substantially the entire base layer may include a knitted material. Typically, the knitted material may include a weft-knitted material. Additionally, or alternatively, the knitted material may include a warp-knitted material.

[0085] Typically, the base layer may comprise a single-piece material and / or a monolithic construction. For example, a single-piece material and / or a monolithic construction may be adapted to form a single-piece upper.

[0086] Monolithic materials and / or integral constructions may include a base layer formed substantially of a single piece of material. Specifically, monolithic materials may not include materials comprising multiple fabric slices sewn together. In other words, monolithic materials and / or integral constructions may include homogeneous and / or continuous constructions, for example, without seams—created by joining different cuts together.

[0087] Specifically, one-piece materials and / or monolithic constructions can be adapted to form one-piece uppers. A one-piece upper can include an upper that substantially comprises a monolithic construction. For example, a one-piece upper can include a base layer of monolithic construction, which, for example, can include a one-piece material. Furthermore, a one-piece upper can include a base layer of monolithic construction and / or one-piece material, on which additional structural elements can be disposed. For example, a one-piece upper can include a base layer of monolithic construction and / or one-piece material, on which reinforcing elements can be disposed. In other words, a one-piece upper and / or monolithic construction can include: no other integral layers are anticipated in the upper besides the base layer. For example, the base layer can be the only material running the entire length of the upper, while other possible local reinforcing elements (e.g., toe reinforcement elements and / or heel reinforcement elements) and / or padding (e.g., padding at the ankle opening) and / or patches can be attached to the base layer.

[0088] Using one-piece materials and / or monolithic construction for the base layer and / or upper contributes to a minimized and simpler upper construction. For example, using one-piece materials and / or monolithic construction for the base layer and / or upper reduces the number of production steps and thus costs. Furthermore, using one-piece materials and / or monolithic construction for the base layer and / or upper contributes to a lightweight (e.g., minimal weight) and flexible upper construction. In particular, using one-piece materials and / or monolithic construction for the base layer and / or upper allows the upper to conform to and / or wrap around the athlete's foot. Therefore, one-piece materials and / or monolithic construction for the base layer and / or upper enhance athlete performance.

[0089] A second aspect of the invention relates to a shoe, particularly an athletic shoe, which includes the upper described above.

[0090] Shoes that include the upper described above inherit all the beneficial effects associated with the upper. Typically, the upper can be included within the shoe to secure it to the midsole. Attached Figure Description

[0091] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. The drawings show:

[0092] Figure 1A An exemplary embodiment of the shoe upper includes a reinforcing element having four reinforcing straps;

[0093] Figure 1B An exemplary embodiment of the shoe upper includes a reinforcing element having two reinforcing bands; and

[0094] Figure 2 : Sports shoes including the upper according to the present invention. Detailed Implementation

[0095] Below, only some possible embodiments of the present invention are described in detail. It should be understood that these exemplary embodiments can be modified in many ways and can be combined with each other as long as they are compatible, and certain features can be omitted as long as they appear unnecessary.

[0096] It should be understood that not all features of the described aspects / embodiments are required to achieve the technical advantages provided by this disclosure. The disclosed aspects / embodiments can be modified by combining certain features of one aspect / embodiment with one or more features of another aspect / embodiment. Specifically, those skilled in the art will understand that features and / or functional elements of one aspect / embodiment can be combined with technically compatible features and / or functional elements of any other aspect / embodiment of this disclosure, provided that the resulting combination falls within the definition of this disclosure.

[0097] While the following embodiments are described primarily with reference to the uppers of athletic shoes (e.g., running shoes), those skilled in the art will recognize that the disclosure of the present invention can be equivalently applied to a number of different technical fields and / or uses. For example, other athletic shoes for basketball, football, American football, tennis, golf, cross-training, hiking, cycling, cross-country running, or snowboarding are also conceivable. The term "athletic shoe" refers to athletic shoes used in sports and does not include use cases not related to sports (such as business shoes, card shoes, or indoor slippers).

[0098] Figure 1A An exemplary embodiment of an upper 100 according to the present invention is shown. The upper 100 includes a base layer 110 and a reinforcing element 120. The reinforcing element is disposed on the inner side of the upper 100, for example, on the side of the upper adapted to inward orientation when the upper is disposed on a shoe. For example, the inner side of the upper 100 may be adapted to directly contact the foot of an athlete wearing the shoe, or indirectly contact the athlete's foot if the athlete is wearing, for example, a sock. In some embodiments, the reinforcing element 120 may be disposed on the outer side of the upper 100, for example, on the visible side of the upper 100 when the upper is disposed on a shoe. Additionally, or alternatively, the reinforcing element 120 may be disposed within the base layer 110. Furthermore, the upper includes a plurality of eyelets 130a, 130b, 130c, 130d, 130e, 130f, 130g (others not labeled).

[0099] The base layer 110 includes a unidirectional stretchable material 115. The base layer 100 substantially uniformly comprises the unidirectional stretchable material 115; for example, the unidirectional stretchable material 115 may be substantially present throughout the entire base layer 110. The unidirectional stretchable material 115 is stretchable in a first direction 100a. Specifically, the first direction 100a has a component parallel to the longitudinal direction of the upper 100. For example, the first direction 100a is substantially parallel to the longitudinal direction. Furthermore, the unidirectional stretchable material 115 is not stretchable in a second direction 100b. The second direction 100b is substantially perpendicular to the first direction 100a. The second direction 100b includes a component parallel to the direction extending from the lateral side (outer side of the foot) to the medial side (inner side of the foot) of the upper. Specifically, the second direction 100b is substantially parallel to the direction extending from the lateral side to the medial side.

[0100] Typically, the base layer 110 and / or the unidirectional stretchable material 115 may comprise a woven material. For example, the woven material may comprise weft yarns and / or warp yarns. Specifically, the weft yarns and / or warp yarns may comprise different stretchabilities. For example, the weft yarn may be more stretchable than the warp yarn. Alternatively, the warp yarn may be more stretchable than the weft yarn. More stretchable yarns, such as warp yarns and / or weft yarns, may be arranged to extend in a first direction 100a. Less stretchable yarns, such as warp yarns and / or weft yarns, may be arranged to extend in a second direction 100b. Yarns extending in the second direction may be substantially non-stretchable. Additionally, or alternatively, the base layer 110 and / or the unidirectional stretchable material 115 may comprise a knitted material.

[0101] The reinforcing element 120 is formed as a connected and / or contiguous unit; for example, the reinforcing element 120 cannot be broken down into unconnected portions. The reinforcing element 120 includes four reinforcing bands 125a, 125b, 125c, and 125d. For example, reinforcing bands 125a and 125b may be associated with the lateral portion of the upper 100. Additionally, reinforcing bands 125c and 125d may be associated with the mid-section of the upper. The reinforcing element 120 is arranged to extend at least partially in a first direction 100a.

[0102] The reinforcing elements 120, particularly the reinforcing bands 125a, 125b, 125c, and 125d, are arranged substantially symmetrically with respect to the mid-sole and lateral portions of the upper 100, as explained above. For example, the reinforcing elements 120 are arranged substantially symmetrically with respect to an axis of symmetry 105. The axis of symmetry 105 is at least partially based on the mid-sole and lateral portions of the upper 100. For example, the portion of the reinforcing element 120 arranged on the mid-sole side of the upper 100 has substantially the same shape and size as the portion of the reinforcing element 120 arranged on the lateral side of the upper 100. In particular, the portion of the reinforcing element 120 arranged on the mid-sole side of the upper 100 is substantially a mirror image of the portion of the reinforcing element 120 arranged on the lateral side of the upper 100 with respect to the axis of symmetry 105.

[0103] Reinforcing band 125a extends from the area associated with eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward the area 104 associated with the heel area. Similarly, reinforcing band 125b extends from the area associated with eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward the area 102 associated with the midsole and / or strobel. For example, area 102 associated with the midsole and / or strobel may include areas adapted to contact the midsole and / or strobel and / or adapted to be secured to the midsole. Furthermore, reinforcing band 125d extends from the area associated with eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward the area 104 associated with the heel area. Similarly, reinforcement band 125c extends from the area associated with eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward the area 102 associated with the midsole and / or the stylist. Specifically, the length of reinforcement bands 125a, 125b, 125c, and 125d may be greater than the width of reinforcement bands 125a, 125b, 125c, and 125d. For example, the length of reinforcement band 125a is greater than the length of reinforcement band 125b.

[0104] The reinforcing bands 125a and 125b associated with the lateral side of the upper 100 may substantially originate from the same eyelets 130e and 130f. Similarly, the reinforcing bands 125c and 125d associated with the midfoot of the upper 100 may substantially originate from the same eyelets (not marked). In some embodiments, the reinforcing bands 125a and 125b associated with the lateral side of the upper 100 may originate from different eyelets. For example, reinforcing band 125b may originate from eyelet 130g, and reinforcing band 125a may originate from eyelet 130d. In particular, reinforcing bands 125a and 125b may originate from eyelets 130d and 130g associated with the forefoot and / or midfoot region of the upper.

[0105] Reinforcing element 120 surrounds eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100. Specifically, reinforcing element 120 surrounds eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g as substantially continuous segments. For example, reinforcing element 120 surrounds all eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100. Specifically, the reinforcing element 120 surrounds the eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100 to connect the eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g associated with the body side of the upper 100 and the eyelets (not marked) associated with the mid-side of the upper. Specifically, the reinforcing element 120 surrounds the eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100 to extend between the intervals between the eyelets 130a, 130b, 130c, 130d, 130e, 130f, and 130g.

[0106] Typically, the reinforcing strips 125a, 125b, 125c, and 125d may comprise non-stretchable materials. For example, the reinforcing strips 125a, 125b, 125c, and 125d may comprise artificial suede and / or non-stretchable fabric and / or leather and / or polymer-based strips. Specifically, the reinforcing strips 125a, 125b, 125c, and 125d may be thermally bonded to the base layer 110. Additionally, or alternatively, the reinforcing strips 125a, 125b, 125c, and 125d may be sewn and / or glued to the base layer 110.

[0107] Figure 1B An exemplary alternative embodiment of an upper 100 including a reinforcing element 120 is shown, wherein the reinforcing element 120 comprises two separate reinforcing elements 120a and 120b. Reinforcing element 120a is arranged in the mid-shoe portion of the upper 100, and reinforcing element 120b is arranged in the lateral portion of the upper. Each of the reinforcing elements 120a and 120b extends along a first direction 100a. Furthermore, each of the reinforcing elements 120a and 120b includes reinforcing bands 125a and 125b. Specifically, reinforcing element 120a includes reinforcing band 125a, and reinforcing element 120b includes reinforcing band 125b. The reinforcing elements 120a and 120b are arranged substantially symmetrically with respect to the mid-shoe portion and the lateral portion of the upper 100. Specifically, the reinforcing elements 120a and 120b are arranged symmetrically with respect to an axis of symmetry 105. For example, reinforcing element 120a is arranged such that it is substantially a mirror image of reinforcing element 120b with respect to the axis of symmetry.

[0108] Reinforcing elements 120a and 120b are arranged to surround at least a portion of the eyelets 130a-130l of the upper 100. For example, reinforcing element 120a arranged on the midfoot side of the upper 100 is arranged to surround at least a portion of the eyelets 130a-130f associated with the midfoot side of the upper. Additionally, reinforcing element 120b arranged on the lateral side of the upper 100 is arranged to surround at least a portion of the eyelets 130g-130l associated with the lateral side of the upper. For example, reinforcing element 120a surrounds the eyelets 130a and 130b of the upper 100. Specifically, reinforcing element 120a surrounds the eyelets 130a and 130b of the upper 100 to extend between the eyelets 130a and 130b; for example, reinforcing element 120a surrounds the eyelets 130a and 130b of the upper 100 as a substantially continuous segment. Additionally, reinforcing element 120b surrounds the eyelets 130k and 130l of the upper 100. Specifically, reinforcing element 120b surrounds the eyelets 130k and 130l of the upper 100 to extend between the eyelets 130k and 130l, for example, reinforcing element 120b surrounds the eyelets 130k and 130l of the upper 100 as a substantially continuous segment.

[0109] The reinforcing band 125a of the reinforcing element 120a extends from the area of ​​the upper 100 associated with the eyelets 130a-130f to the area of ​​the upper 100 associated with the heel area. Furthermore, the reinforcing band 125b of the reinforcing element 120b extends from the area of ​​the upper 100 associated with the eyelets 130g-130l to the area of ​​the upper 100 associated with the heel area.

[0110] Figure 2 A side view of an exemplary athletic shoe 200 is shown, the shoe comprising: an upper 210 according to the invention, and a midsole 205. The upper 210 includes a base layer comprising a unidirectional stretchable material that is stretchable in a first direction 200a and substantially non-stretchable in a second direction 200b. The upper also includes eyelets 230a, 230b, 230c, 230d, 230e, 230f, and 230g. The upper 210 includes at least one reinforcing element 220 arranged to restrict the stretchability of the unidirectional stretchable material at least in the first direction 200a.

[0111] Reinforcing element 220 is disposed on the lateral side of upper 210. Typically, upper 100 may include additional reinforcing elements (not shown) on the midfoot side. For example, reinforcing elements 220 on the midfoot and lateral sides of upper 100 may be arranged symmetrically with respect to the midfoot and lateral portions of upper 100. Reinforcing element 220 includes reinforcing band 225. Reinforcing band 225 extends substantially parallel to the first direction 200a. Specifically, reinforcing band 225 extends from the area associated with eyelets 230a, 230b, 230c, 230d, 230e, 230f, 230g to the area 202 associated with the heel area. Additionally, or alternatively, reinforcing element 220 may include additional reinforcing band. For example, the reinforcing element 220 may include a reinforcing strip extending from the area associated with eyelets 230a, 230b, 230c, 230d, 230e, 230f, 230g to the area 204 associated with the midsole 205 and / or the stylist.
