Description

[Technical Field]

[0001] The present invention relates to an upper for a shoe, in particular a sports shoe, comprising a base layer and at least one reinforcing element. In particular, the base layer comprises a unidirectionally stretchable material that is stretchable in a first direction. [Background technology]

[0002] Aiming to maximize an athlete's performance is at the very heart of the development and evolution of athletic equipment. This is particularly true for sports shoes, such as running shoes, where an athlete's performance is critically dependent on the performance of the shoe. Accordingly, great efforts have been made to optimize the performance of sports shoes, and in particular running shoes.

[0003] One of the critical components of sports shoes, and particularly running shoes, is the upper, as it enables the shoe to hold the athlete's foot while walking and / or running, and must be configured to conform and / or adapt to the athlete's foot in order to provide optimal comfort and support to the athlete.

[0004] One approach to designing shoe uppers involves using a one-piece upper, for example, an upper with seams only in the heel region, where the one-piece upper is non-stretchable. Using such a one-piece upper has been found to simplify shoe manufacturing. It also reduces the number of stitches required, which is advantageous because stitches in an upper can cause irritation to a wearer's foot. Generally, when a one-piece upper is used, the upper must be non-stretchable to ensure that the upper maintains a snug fit to the foot during athletic activities. However, using a non-stretchable upper prevents the upper from conforming to the complex shape of the shoe last and / or foot. Therefore, a non-stretchable upper cannot achieve the desired shoe fit, thereby reducing the athlete's comfort and performance.

[0005] A complementary approach to designing a one-piece upper involves using elastic materials. However, the use of elastic materials results in the upper being unable to adequately hold and / or support the athlete's foot during walking and / or running. This lack of stability necessitates the use of large and / or numerous reinforcing elements to achieve the desired stability. These reinforcing elements are stiff and heavy, thereby negating the ability of the elastic material to conform to the complex shape of the shoe last and / or foot. Thus, the additional weight and stiffness of the upper reduces comfort and the athlete's performance.

[0006] In this regard, U.S. Patent No. 9,826,799 describes a synthetic shell for an upper that includes a base layer and a fiber-reinforced layer. The base layer may include mesh or other types of textile material and may extend across at least a lateral portion of the generally foot-shaped interior region of the upper. The fiber-reinforced layer may be at least partially bonded to the base layer. The fiber-reinforced layer may extend from at least a lower portion of the base layer generally corresponding to the periphery of the midsole to at least an upper portion of the base layer generally corresponding to a portion of the instep region. The fiber-reinforced layer may include a plurality of strips extending from the lower portion to the upper portion, the strips being separated by inter-strip gaps within the fiber-reinforced layer.

[0007] Therefore, there is a need for an improved upper for shoes, particularly sports shoes, that addresses at least some of the above-described disadvantages of the prior art and further improves other aspects. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] U.S. Patent No. 9,826,799 Summary of the Invention

[0009] A first aspect of the present invention relates to an upper, in particular an upper for a sports shoe, comprising a base layer including a unidirectionally stretchable material, the unidirectionally stretchable material being stretchable in a first direction, the upper further comprising at least one reinforcing element, the reinforcing element being arranged to limit the stretchability of the unidirectionally stretchable material in at least the first direction.

[0010] A unidirectionally stretchable material is stretchable in a first direction. For example, the term unidirectional may refer to a first direction. In general, the first direction may include a direction relative to a planar state of the upper. The planar state of the upper may include a state in which the upper is not attached to a shoe, e.g., a state in which the upper is not secured to a midsole of a shoe. For example, the planar state of the upper may include a state in which the upper is unfolded and flat.

[0011] A base layer comprising a one-way stretchable material may comprise the one-way stretchable material throughout essentially its entire range. For example, the one-way 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 upper may comprise the one-way stretchable material.

[0012] The upper further comprises at least one reinforcing element. The at least one reinforcing element may include a connected reinforcing element. Additionally or alternatively, the reinforcing elements may include at least two disconnected reinforcing elements. The at least one reinforcing element may be arranged to limit the stretchability of the one-way stretchable material in at least a first direction. Specifically, the at least one reinforcing element may be arranged to locally limit the stretchability of the one-way stretchable material. For example, the at least one reinforcing element may limit the stretchability of the one-way stretchable material in at least one region of the base layer. Specifically, this at least one region of the base layer may be related to the location of the at least one reinforcing element relative to the base layer. For example, a first reinforcing element may be arranged in a first location to limit the stretchability of the base layer in a first region related to the first location. Limiting the stretchability of the one-way stretchable material in at least a first direction may include reducing the stretchability of the one-way stretchable material in at least the first direction.

[0013] An upper comprising a one-way stretchable material and at least one reinforcing element positioned to limit the stretchability of the upper in at least a first direction allows for control of the stretchability of the upper in at least a first direction. For example, controlling the stretchability in at least a first direction allows for tuning the stretchability toward a target stretchability and / or adjusting the stretchability to suit the athlete's needs. Controlling the stretchability in at least a first direction also allows the fabric of the upper, e.g., the base layer, to conform to atypical and / or extreme shapes of lasts, such as lasts with highly curved regions. For example, lasts with radial and / or extreme shape regions may include protruding volume zones and / or curved sculpted zones, and / or at least one transition area that changes from convex to concave and vice versa. Using an upper comprising a one-way stretchable material and at least one reinforcing element positioned to limit the stretchability of the upper in at least a first direction thereby allows for the creation of a perfect fit upper using a one-piece base layer and / or one-piece upper, even with extreme shape lasts. In particular, the use of a one-piece upper reduces the number of manufacturing steps and further reduces the weight of the final shoe, e.g., the shoe that includes the upper. Thus, the upper described above improves manufacturing efficiency and contributes to a minimal shoe weight, which further contributes to optimizing the performance of the athlete wearing the shoe.

[0014] Generally, a unidirectionally stretchable material may include a material that is essentially stretchable in only a first direction. Specifically, being essentially stretchable in only a first direction may include the material being essentially non-stretchable in a second direction. For example, the second direction may be perpendicular to the first direction.

[0015] For example, the term unidirectional may refer to a material that is essentially stretchable in only one direction, specifically a first direction. In other words, a unidirectionally stretchable material may be stretchable only in the first direction. For example, a unidirectionally stretchable material may not be stretchable in a second direction that is perpendicular to the first direction. In particular, a unidirectionally stretchable material may be stiff in the second direction. In particular, being stiff in the second direction may include a material that is much less stretchable in the second direction than in the first direction.

[0016] Generally, the determination of the stretchability of a material and / or fabric can be based on its elongation under a load test. For example, applying a tensile force to a base layer in a first direction can stretch the base layer a first amount, and applying a tensile force in a second direction of the same magnitude as the first force can stretch the base layer 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. Specifically, the first amount can be greater than the second amount, e.g., by at least 1.2 times, preferably at least 1.4 times, more preferably at least 1.6 times, even more preferably at least 1.8 times, and most preferably at least 2 times. Specifically, the ratio between the first amount and the second amount can depend at least in part on the magnitude of the applied force, e.g., the magnitude of the first force. For example, the ratio can be nonlinearly dependent on the applied force. Generally, the second direction can be perpendicular to the first direction. The second direction may include a direction relative to a planar state of the upper.

[0017] The use of a one-way stretchable material that is essentially stretchable in only a first direction allows for precise adjustment of stretchability in the first direction. In particular, being essentially stretchable in only a first direction can ensure that it is sufficient to limit the stretchability of the base layer and / or upper in the first direction; for example, additional reinforcing elements adapted to limit stretchability in a second direction are not required. This can ensure a good fit of the upper and / or shoe comprising the upper. A good fit of the upper and / or shoe improves the comfort of the shoe, thereby optimizing the athlete's performance. Furthermore, the use of a one-way stretchable material that is essentially stretchable in only a first direction can ensure that the upper is sufficiently stable to support the athlete's foot (especially during walking and / or running) while at the same time being stretchable in selected areas to adapt to the shape of the shoe last and foot.

[0018] Specifically, the second direction may include a component parallel to a direction extending from the lateral side of the upper to the medial side of the upper. For example, the second direction may be essentially parallel to a direction extending from the lateral side to the medial side of the upper.

[0019] The lateral side of the upper and / or the medial side of the upper may refer to the corresponding side of the shoe when the upper is secured to the sole of the shoe, for example. The direction extending from the lateral side of the upper to the medial side of the upper may include a direction based on the planar state of the upper, e.g., when the upper may have essentially two-dimensional extent. For example, the second direction, e.g., a direction in which the material is essentially non-stretchable, may include a component parallel to the direction extending from the lateral side of the upper to the medial side of the upper. Specifically, including a component parallel to the direction extending from the lateral side of the upper to the medial side of the upper may include an angle between the second direction and the direction extending from the lateral side of the upper to the medial side of the upper being 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 essentially parallel to the direction extending from the lateral side to the medial side. For example, the second direction and the direction extending from the lateral side to the medial side may comprise essentially the same direction, for example, the angle between the second direction and the direction extending from the lateral side to the medial 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°.

[0020] The first direction may include a component parallel to the longitudinal direction of the upper and / or shoe, for example, the first direction may be essentially parallel to the longitudinal direction.

[0021] The longitudinal direction of the upper and / or shoe may include a direction extending from an area of ​​the upper and / or shoe associated with the heel to an area of ​​the upper and / or shoe associated with the forefoot and / or toe. For example, the area of ​​the shoe associated with the heel may include an area adapted to receive the heel and / or rearfoot of a wearer, and the area associated with the forefoot and / or toe may include an area adapted to receive the forefoot and / or toe of a wearer.

[0022] Specifically, including a component parallel to the longitudinal direction of the upper and / or shoe may include an angle between the first direction and the longitudinal direction of the upper and / or shoe being 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 essentially parallel to the longitudinal direction of the upper and / or shoe. For example, the first direction and the longitudinal direction of the upper and / or shoe may include essentially the same direction, e.g., the angle between the first direction and the longitudinal direction of the upper and / or 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 a ridge of the last, e.g., the first direction may at least partially follow a ridge of the last.

[0023] A material that is stretchable in a direction that includes a component parallel to the longitudinal direction of the upper and / or shoe improves the conformability of the upper to the last and / or shoe. For example, stretchability in a direction that includes a component parallel to the longitudinal direction of the upper and / or shoe allows the upper to conform to the last and / or shoe even when the last has a radial and / or extreme shape. Thus, a material that is stretchable in a direction that includes a component parallel to the longitudinal direction of the upper and / or shoe allows the use of a one-piece upper, e.g., an upper and / or base layer that is formed essentially from one piece.

[0024] Additionally, having the first direction include a component parallel to the ridges of the last allows the material to extend along the ridges of the last, thereby accommodating a convex portion of the last while remaining attached to an adjacent concave portion of the last, e.g., a concave portion corresponding to the arch of the foot.

[0025] In general, the at least one reinforcing element may be arranged such that the at least one reinforcing element extends at least partially in a first direction.

[0026] For example, extending at least partially in a first direction may include at least one reinforcing element having a dimension in the first direction, e.g., having a component extending in the first direction. Also, extending at least partially in a first direction may include at least one reinforcing element having a dimension and / or extent in a second direction. In general, at least one reinforcing element may have a dimension and / or extent in both the first and second directions. For example, extending at least partially in a first direction may include a dimension and / or extent in the first direction that is greater than a dimension and / or extent in the second direction. In particular, having a dimension and / or extent in the first direction that is greater than a dimension and / or extent in the second direction may include a projection of at least one reinforcing element in the first direction that is greater than a projection of the reinforcing element in the second direction.

[0027] Reinforcing elements arranged to extend at least partially in a first direction may ensure that the stretchability of the one-way stretchable material can be limited in selected and / or targeted areas, such as selected and / or targeted portions of the upper. In particular, reinforcing elements arranged to extend at least partially in a first direction may make it possible to limit the stretchability of the one-way stretchable material across the dimension and / or extent of the reinforcing elements in the first direction. Reinforcing elements arranged to extend at least partially in a first direction thus allow for precise and targeted manipulation of the stretchability of the one-way stretchable material, thereby contributing to optimizing the adaptation of the upper and / or base layer to shoe lasts, such as lasts with extreme and / or atypical shapes, and thus to the shape of the athlete's foot.

[0028] The at least one reinforcing element may be arranged to be located on a surface of the base layer, for example, the at least one reinforcing element may be arranged to be located on an inner surface of the base layer.

[0029] The base layer may have two surfaces, for example, an inward-facing surface and an outward-facing surface. Specifically, the inward-facing surface may include the surface opposite the outward-facing surface, for example, when the upper is in a flat state. For example, the inward-facing surface may include a surface that, when placed in, for example, a shoe, is adapted to face toward the interior of the shoe, i.e., toward the space for receiving the wearer's foot. Specifically, the inward-facing surface may be adapted to directly or indirectly contact the athlete's foot. Also, the outward-facing surface may constitute the outer surface of the shoe.

[0030] Disposing the reinforcing element on a surface of the base layer, e.g., on an inner surface of the base layer, may include the reinforcing element being at least partially fixed to and / or at least partially contacting the surface of the base layer. For example, the reinforcing element may be placed on the surface of the base layer.

[0031] 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, for example, the reinforcing element may be disposed only on the outer surface. Generally, the reinforcing element may be disposed on 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.

[0032] Positioning the reinforcing elements on the surface of the base layer can simplify and / or optimize the process of positioning the reinforcing elements on the upper. Therefore, the number of manufacturing steps required can be minimized, which can speed up the manufacturing of the upper. Speeding up the manufacturing of the upper can contribute to optimized manufacturing and maximized efficiency of the upper.

[0033] In particular, locating the at least one reinforcing element on the outer surface makes the inner surface of the upper smoother, thereby minimizing discontinuities on the inner surface and thus making the shoe more comfortable.

[0034] Furthermore, locating at least one reinforcing element on the medial surface contributes to a smoother and cleaner outer surface of the base material and / or upper, thereby optimizing the athlete's control over the ball when kicking it in sports such as football.

[0035] Generally, at least one reinforcing element may be arranged such that at least a portion of the reinforcing element is heat-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, adhesively 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 via a fusible thread, e.g., a fusible thread incorporated into the base layer and / or the reinforcing element. Specifically, the fusible thread may be incorporated into the base material and / or the material of the at least one reinforcing band.

[0036] Additionally or alternatively, at least a portion of the reinforcing element may be embroidered into the base layer. For example, the entire reinforcing element may be embroidered into the base layer. Specifically, at least a portion of the reinforcing element may be embroidered into the base layer at least in part using high strength threads and / or hot melt threads and a subsequent heat treatment.

[0037] For example, at least a portion of the reinforcing element may be heat-bonded to a portion of a surface of the base layer. For example, at least a portion of the reinforcing may be heat-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 may be sewn to the base layer. For example, at least a portion of the reinforcing may be sewn to a surface, e.g., the inner and / or outer surface, of the base layer. In some embodiments, a first portion of the reinforcing element may be heat-bonded to the base layer and a second portion of the reinforcing element may be sewn to the base layer.

[0038] Heat-bonding and / or sewing at least a portion of the reinforcement to the base layer can ensure that the reinforcing element is adequately secured to the base layer without substantially modifying the base layer. Also, heat-bonding and / or sewing at least a portion of the reinforcement to the base layer can speed up the process of attaching the reinforcing element to the base layer, thereby streamlining the manufacturing of the upper and / or shoe.

[0039] The at least one reinforcing element may be arranged to be essentially symmetrical about the medial and lateral portions of the upper.

[0040] In general, being essentially symmetrical with respect to the medial and lateral portions of the upper may include matching at least one characteristic of the reinforcing elements associated with the medial and lateral sides. For example, the number of reinforcing bands associated with the medial portion of the upper may match the number of reinforcing bands associated with the lateral portions of the upper. In other words, the medial portion of the upper may include the same number of reinforcing bands as the lateral portions of the upper. Also, the reinforcing bands on the medial side of the upper may have the same width as the reinforcing bands on the lateral sides.

[0041] Additionally or alternatively, being essentially symmetrical with respect to the medial and lateral portions of the upper may include the portions of the reinforcing elements associated with the medial side of the upper being essentially congruent with the portions of the reinforcing elements associated with the lateral side of the upper. For example, congruent may include the medial portions of the reinforcing elements having the same shape and size.

[0042] Additionally or alternatively, being essentially symmetrical with respect to the medial and lateral portions of the upper may include the portion of the reinforcing element associated with the medial side of the upper being essentially similar to the portion of the reinforcing element associated with the lateral side of the upper. For example, similarity may include the medial portion of the reinforcing element having the same shape. Specifically, similarity may not include properties such as the position, scale, orientation, and / or reflection of each portion of the reinforcing element. For example, the medial portion of the reinforcing element may be considered similar if, for example, the lateral portion of the reinforcing element matches the medial portion of the reinforcing element up to a certain scaling.

[0043] For example, the upper may be configured such that the medial portion of the upper and the lateral portion of the upper essentially define an axis of symmetry for the upper. Being symmetrically arranged with respect to the medial portion and the lateral portion of the upper may include that at least one reinforcing element may be symmetrical with respect to the axis of symmetry. For example, the axis of symmetry of the at least one reinforcing element may essentially coincide with the longitudinal axis of symmetry of the upper. For example, if the at least one reinforcing element includes only one reinforcing element, being symmetrically arranged may include that the reinforcing element is symmetrical and that the axis of symmetry of the reinforcing element may coincide with the axis of symmetry of the upper. Additionally or alternatively, if the at least one reinforcing element includes at least two elements, being symmetrically arranged may include that the at least two reinforcing elements are arranged symmetrically with respect to the axis of symmetry of the upper. For example, the number and / or alignment of the reinforcing elements associated with the medial side of the upper may correspond to the number and / or alignment of the reinforcing elements associated with the lateral side of the upper.

[0044] Additionally or alternatively, being essentially symmetrical with respect to the medial and lateral portions of the upper may include at least a subset of bands associated with the medial side of the upper being symmetrical with at least a subset of bands associated with the lateral side of the upper. For example, a first lateral reinforcement band disposed on the lateral portion of the upper may be essentially symmetrical with a first medial reinforcement band disposed on the medial portion of the upper. Specifically, the first lateral reinforcement band and the first medial reinforcement band may each include a reinforcement band extending from a region of the upper associated with the eyestay to a region of the upper associated with the heel area. Additionally or alternatively, the upper may include a second lateral reinforcement band and / or a second medial reinforcement band, and for example, the number of second reinforcement bands on the medial and lateral portions may differ. For example, the upper may include a second lateral reinforcement band and a second medial reinforcement band. In particular, the second lateral reinforcement band may have a shape and / or size and / or orientation that is different from the shape and / or size and / or orientation of the second inner reinforcement band.

[0045] Arranging the at least one reinforcing element to be essentially symmetrical with respect to the medial and lateral portions of the upper can ensure that the stretchability of the one-way stretchable material in the medial region is essentially the same as the stretchability of the one-way stretchable material in the lateral region. Thus, the stretchability of the upper can be essentially symmetrical with respect to the medial and lateral portions of the upper. The symmetrical stretchability of the upper can contribute to optimized adaptation of the upper to shoe lasts, such as atypical and / or extreme-shaped shoe lasts, and to optimized adaptation of the upper to an athlete's foot.

[0046] In some embodiments, the at least one reinforcing element may surround at least a portion of an eyestay of the upper, for example, the at least one reinforcing element may surround the entire eyestay of the upper.

[0047] The material associated with at least one reinforcing element may at least partially surround at least a portion of the eyestays of the upper. For example, at least one reinforcing element may surround at least two adjacent eyestays of the upper. Additionally or alternatively, the reinforcing element may surround non-adjacent eyestays of the upper; for example, between two eyestays that are surrounded and / or enclosed by the upper, there may be at least one eyestay that is not surrounded and / or enclosed by the reinforcing element.

[0048] Generally, the at least one reinforcing element may surround at least a portion of the eyestay so as to surround the eyestay symmetrically with respect to the axis of symmetry of the upper. For example, the inner portion of the eyestay may be located on the inner side of the upper, and the lateral portion of the eyestay may be located on the lateral side of the upper. Specifically, the at least one reinforcing element may be arranged to surround the same number of lateral and inner eyestays. Specifically, the at least one reinforcing element may surround the inner and / or lateral eyestays of at least two, preferably at least three, more preferably at least four, and most preferably at least five eyestays. Specifically, the at least one reinforcing element may surround all of the eyestays of the upper, for example, all of the inner and lateral eyestays of the upper.

[0049] Additionally or alternatively, the eyestays may be separated from one another by a gap. For example, a first eyestay may be separated from a second eyestay by a first gap. Specifically, at least one reinforcing element may surround the eyestays to extend between the gaps between adjacent eyestays. For example, at least one reinforcing element may surround the first and second eyestays to cover the first gap. For example, at least a portion of the gap may constitute a part of the reinforcing element.

[0050] Arranging at least one reinforcing element to surround at least a portion of the upper's eyestays allows for limiting the stretchability of the unidirectionally stretchable material in at least a first direction. For example, the eyestays may be arranged to essentially follow the longitudinal direction of the upper and / or shoe. In particular, arranging at least one reinforcing element to surround at least a portion of the upper's eyestays improves the stability of the upper in the area associated with the eyestays, thereby contributing to improved support and fixation of the foot.

[0051] The reinforcing elements surrounding at least a portion of the eyestays of the upper may further act as reinforcing elements to prevent wear and tear on the base material / layers around the eyestays due to tension applied by the laces. In other words, the reinforcing elements surrounding at least a portion of the eyestays of the upper may be (primarily) directed to reinforcing the material around the eyestays and (only secondarily) directed to restricting the stretchability of the one-way stretchable material. In particular, adapting the reinforcing elements to surround at least a portion of the eyestays with respect to restricting the stretchability of the (at least) one-way stretchable material may be an optional feature and may, for example, be omitted.

[0052] Specifically, the at least one reinforcing element may surround the eyestay so as to surround the eyestay as an essentially continuous segment.

[0053] For example, at least one reinforcing element may surround a continuous set of eyestays. Specifically, at least one reinforcing element may surround the first and last eyestays, as well as all eyestays between them. Surrounding the eyestays as an essentially continuous segment may include at least one reinforcing element extending between the first and last eyestays. For example, at least one reinforcing element may extend essentially continuously between the first and last eyestays. Specifically, extending essentially continuously between the first and last eyestays may include extending between the first and last eyestays without any gaps, for example, without any portion not surrounded by the at least one reinforcing element.

[0054] Arranging the at least one reinforcing element to surround the eyestay as an essentially continuous segment allows for limiting the stretch of the unidirectionally stretchable material in at least a first direction. In particular, arranging the at least one reinforcing element to surround the eyestay as an essentially continuous segment improves the stability of the upper in the area associated with the eyestay, thereby contributing to improved support and fixation of the foot.

[0055] Generally, the at least one reinforcing element may comprise at least one reinforcing band. Specifically, the at least one reinforcing band may extend from a region of the upper associated with the eyestay to a region of the upper associated with the midsole and / or the strobel. Additionally or alternatively, the at least one reinforcing band may extend from a region of the upper associated with the eyestay to a region of the upper associated with the heel area.

[0056] The reinforcing band may configure at least a portion of the reinforcing element such that the extent of the reinforcing band in a first direction is greater than the extent of the reinforcing band in a second direction. For example, the reinforcing band may have an essentially rectangular shape, e.g., one greater extent in a first direction and a smaller extent in a second direction. In particular, the reinforcing band may have the shape of a strip.

[0057] Additionally or alternatively, at least one reinforcing band may extend from a region of the upper associated with the eyestay to a region of the upper associated with the midsole and / or Strobel, which may constitute a region of the upper adapted to contact the midsole and / or Strobel.

[0058] In particular, the upper may include a reinforcing band extending from the area associated with the eyestay toward the area associated with the midsole and / or strobel if the corresponding shoe is adapted for sports involving multidirectional movement and / or high speed, e.g., (large) lateral movements, such as sprinting, football, basketball, baseball, and / or tennis. Additionally or alternatively, the upper may include a reinforcing band extending from the area associated with the eyestay toward the area associated with the midsole and / or strobel if the base material is very lightweight.

[0059] Additionally or alternatively, the region of the upper associated with the midsole and / or strobel may include a region of the upper adapted to be secured to the midsole and / or strobel, for example, by gluing. For example, the reinforcement band may extend beyond the bite line and / or tooling top line, e.g., the top edge of the midsole.

[0060] For example, the reinforcement band may start in a region of the upper associated with the eyestay and end in a region associated with the midsole and / or Strobel. In particular, the reinforcement band may be configured such that the direction associated with the greater extent of the reinforcement band (the main direction) may include a component parallel to the direction pointing from the region of the upper associated with the eyestay toward the region associated with the midsole and / or Strobel.

[0061] Additionally or alternatively, at least one reinforcement band may extend from a region of the upper associated with the eyestays to a region of the upper associated with the heel area. For example, the reinforcement band may begin in a region of the upper associated with the eyestays and end in a region associated with the heel area. For example, the reinforcement band may end in a region associated with the rear end of the heel portion, such as a rear seam of the heel portion. Specifically, the reinforcement band may begin in the eyestay region of the forefoot, such as the first and / or second lace eyelets in the forefoot area of ​​the upper. Specifically, the reinforcement band may be configured such that a direction associated with the greater extent of the reinforcement band (a primary direction) may include a component parallel to a direction pointing from the region of the upper associated with the eyestays toward the region associated with the heel area.

[0062] A reinforcing element comprising at least one reinforcing band allows for effective and efficient use of the reinforcing element, e.g., stiffening a large portion of the base layer while using a minimal portion of the reinforcing element. Specifically, the reinforcing band may have a larger dimension and / or extent in a direction essentially parallel to a first direction, i.e., the direction in which the unidirectionally stretchable material is stretchable, and a smaller dimension and / or extent in a second direction, i.e., the direction in which the unidirectional material may not be stretchable. Thus, the use of a reinforcing band minimizes the portion of the base layer comprising the reinforcing band and / or minimizes the amount of reinforcing band required to achieve the intended stiffening and / or stretch restriction. Minimizing the amount of reinforcing band required to achieve the intended stiffening and / or stretch restriction can minimize the weight of the upper and / or shoe. Minimizing the weight of the upper and / or shoe can contribute to improved athlete performance and may also reduce manufacturing costs, e.g., by reducing the amount of material required and / or speeding up production.

[0063] In particular, a reinforcing element including at least one reinforcing band extending from the region of the upper associated with the eyestay to the region of the upper associated with the heel area creates a tension line from the forefoot to the heel area. This allows the at least one reinforcing element to provide sufficient support and fixation for the foot required for any sport, particularly for sports involving linear movement, such as marathons. In particular, for sports involving linear movement, such as running, at least one reinforcing band extending from the region of the upper associated with the eyestay to the region of the upper associated with the heel area is sufficient, and a reinforcing band extending from the region of the upper associated with the eyestay to the region of the upper associated with the midsole and / or strobel may not be necessary to ensure sufficient support for the foot.

[0064] Generally, the at least one reinforcement band may originate in a region located below the eyestay of the upper, for example, there may be a distance between the eyestay of the upper and the at least one reinforcement band.

[0065] Additionally or alternatively, at least one reinforcing band may extend from an essentially continuous segment that surrounds the eyestay of the upper.

[0066] For example, at least one reinforcing band may begin at an essentially continuous segment surrounding the eyestay of the upper. For example, at least one reinforcing band may begin at an essentially continuous segment surrounding the eyestay of the upper and extend toward a region associated with the midsole and / or Strobel. Additionally or alternatively, at least one reinforcing band may begin at an essentially continuous segment surrounding the eyestay of the upper and extend toward a region associated with the heel area. In some embodiments, the upper may include a first reinforcing band extending from the essentially continuous segment toward a region associated with the midsole and / or Strobel, and a second reinforcing band extending from the essentially continuous segment toward a region associated with the heel area. Specifically, the upper may include first and second reinforcing bands on the medial and lateral sides of the midsole; for example, the upper may include four reinforcing bands. Specifically, the reinforcing bands may be symmetrically arranged on the medial and lateral sides of the upper.

[0067] A reinforcing band extending from an essentially continuous segment surrounding the eyestay of the upper allows for localized, efficient stiffening of the base layer and / or the upper in at least a first direction. Also, because the reinforcing element comprises a continuous reinforcing element, e.g., an essentially continuous segment from which the reinforcing band extends, placement of the reinforcing element in the base layer, e.g., on the surface of the base layer, may be simplified. Simplifying placement of the reinforcing element in the base layer may speed and / or optimize manufacturing of the upper.

[0068] Generally, the upper may include at least one reinforcement band. Additionally or alternatively, the upper may include at least two reinforcement bands. Additionally or alternatively, the upper may include at least three reinforcement bands. Additionally or alternatively, the upper may include at least four reinforcement bands. In some embodiments, the upper may include at most 20 reinforcement bands. Additionally or alternatively, the upper may include at most 16 reinforcement bands. Additionally or alternatively, the upper may include at most 12 reinforcement bands. Additionally or alternatively, the upper may include at most 8 reinforcement bands. Additionally or alternatively, the upper may include at most 6 reinforcement bands.

[0069] For example, the upper may include at least two reinforcement bands, e.g., a first reinforcement band on the medial side of the base layer and a second reinforcement band on the lateral side of the base layer. Additionally or alternatively, the upper may include at least two reinforcement bands on each side, e.g., two reinforcement bands on the medial side and two reinforcement bands on the lateral side. Additionally or alternatively, the upper may include at most 20 reinforcement bands. For example, the upper may include at most 20 reinforcement bands in total, e.g., at most 20 reinforcement bands on the medial side and at most 20 reinforcement bands on the lateral side. In some embodiments, the number of reinforcement bands on the medial and / or lateral sides may be at most 20.

[0070] An upper comprising at least two reinforcing bands and / or at most 20 reinforcing bands ensures sufficient restriction of the stretchability of the base layer and / or upper in at least a first direction, while at the same time ensuring efficient utilization of the reinforcing elements, e.g., achieving the intended restriction and / or stiffening using a minimum number of reinforcing bands.

[0071] Generally, the width of at least one reinforcement band may be at least 0.25 cm. Additionally or alternatively, the width of at least one reinforcement band may be at least 0.5 cm. Additionally or alternatively, the width of at least one reinforcement band may be at least 0.75 cm. Additionally or alternatively, the width of at least one reinforcement band may be at least 1 cm. Additionally or alternatively, the width of at least one reinforcement band may be at least 1.25 cm. Additionally or alternatively, the width of at least one reinforcement band 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.

[0072] The width of at least one reinforcement band may include the extent of the reinforcement band in a direction associated with a smaller extent, e.g., the smaller extent of the reinforcement band. A reinforcement band having a width of at least 0.25 cm may contribute to limiting the stretchability of a unidirectionally stretchable material in at least a first direction. Specifically, a reinforcement band having a width of at least 0.25 cm may ensure that the intended limit of stretchability and / or the intended stiffening of the upper is achieved. Thus, the use of a reinforcement band having a width of at least 0.25 cm may improve support and / or fixation of the foot.

[0073] Generally, at least one reinforcing element may comprise a non-elastic material, for example, at least one reinforcing element may comprise synthetic suede and / or non-elastic fabric and / or leather and / or polymer-based tape.

[0074] The non-stretchable material may include a material that is less stretchable in one direction than the stretchable material of the base layer. For example, the non-stretchable material may include a material that is not stretchable in all directions, e.g., a first direction and a second direction, where the first direction and the second direction are essentially perpendicular. For example, the non-stretchable material may include an essentially rigid material. In particular, the non-stretchable material may be configured to be heat-bonded and / or sewn to the base layer. Specifically, the reinforcement may include synthetic suede. Additionally or alternatively, the non-stretchable material may include a non-stretchable fabric. Additionally or alternatively, the non-stretchable material may include natural or synthetic leather. Additionally or alternatively, the non-stretchable material may include a polymer-based tape. For example, the polymer-based tape may include polyurethane.

[0075] Using a reinforcing element comprising a non-elastic material can ensure that the reinforcing element limits the stretchability of the unidirectionally stretchable material in at least a first direction. Thus, the reinforcing element comprising a non-elastic material contributes to stiffening at least a portion of the base layer and / or upper. The stiff portions of the base layer and / or upper maximize foot support and / or foot immobilization.

[0076] In some embodiments, the base layer may include a woven material having weft and warp yarns. Specifically, the weft yarns may include at least one weft yarn, and the warp yarns may include 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.

[0077] Specifically, in a preferred embodiment, the at least one weft yarn may be more stretchable than the at least one warp yarn, since adjusting the at least one warp yarn may be more difficult, thereby slowing down production.

[0078] For example, essentially the entire base layer may comprise a woven material. The woven material may comprise at least one weft thread and / or at least one warp thread. Generally, at least one weft thread and at least one warp thread of the woven material may be arranged to cross each other essentially at right angles. For example, at least one weft thread may be more stretchable than at least one warp thread. In particular, all weft threads may be more stretchable than the warp threads. Specifically, all weft threads may have a first stretchability and all warp threads may have a second stretchability. For example, the first stretchability may be greater than the second stretchability, e.g., the weft threads may be more stretchable than the warp threads. In other words, all weft threads may have essentially the same stretchability and all warp threads may have essentially the same stretchability. For example, the warp threads may be essentially instretchable. In particular, the weft threads may be stretchable and the warp threads may be instretchable. Specifically, the weft yarns may run in a first direction and / or the warp yarns may run in a second direction, e.g., the weft yarns may run in a first direction and the warp yarns may run in a second direction to at least partially define a material that is stretchable in one direction.

[0079] For example, the more stretchy yarns, e.g., weft yarns, may comprise mechanically high stretch yarns, particularly high crimp yarns. For example, the high crimp yarns may comprise bulky textured yarns that have been processed to possess a high degree of crimp. Additionally or alternatively, the high stretch yarns may comprise side-by-side yarns.

[0080] In some embodiments, differential stretch of the woven material may be achieved by placing elastane yarns every few weft yarns.

[0081] Additionally or alternatively, at least one warp yarn may be more stretchable than at least one weft yarn. Specifically, all warp yarns may be more stretchable than all weft yarns. Specifically, all warp yarns may have a first stretchability and all weft yarns may have a second stretchability. For example, the first stretchability may be greater than the second stretchability, e.g., the warp yarns may be more stretchable than the weft yarns.

[0082] In some embodiments, the weft yarns may have different elasticity. For example, a first weft yarn may have a first elasticity and a second weft yarn may have a second elasticity. Additionally or alternatively, the warp yarns may have different elasticity. For example, a first warp yarn may have a first elasticity and a second warp yarn may have a second elasticity. Specifically, the elasticity of the weft and / or warp yarns may be such that the effective elasticity of the weft yarns, e.g., the elasticity associated with the weft yarns, is greater than the effective elasticity of the warp yarns, e.g., the elasticity associated with the warp yarns.

[0083] A fabric including weft and warp yarns with different stretch properties can contribute to a unidirectionally stretchable material. Specifically, the weft and / or warp yarns can at least partially define first and second directions, e.g., a stretchable direction and a non-stretchable direction, of the unidirectionally stretchable material. Thus, a fabric including weft and warp yarns with different stretch properties can contribute to the adaptability of the upper to a foot and / or shoe last, e.g., a shoe last with an extreme shape. Specifically, the fabric can contribute to an optimal fit of the upper and / or shoe to an athlete's foot, thereby maximizing comfort and thus optimizing performance.

[0084] Additionally or alternatively, the base layer may comprise a knitted material.

[0085] For example, only a portion of the base layer may comprise a knitted material. In some embodiments, essentially the entire base layer may comprise a knitted material. Generally, the knitted material may comprise a weft-knitted material. Additionally or alternatively, the knitted material may comprise a warp-knitted material.

[0086] In general, the base layer may comprise a unitary material and / or a unitary structure, for example, the unitary material and / or the unitary structure may be adapted to form a one-piece upper.

[0087] A one-piece material and / or unitary structure may include a base layer formed from essentially a single piece of material. In particular, a one-piece material does not include a material that includes multiple cut pieces of fabric sewn together. In other words, a one-piece material and / or unitary structure may include a homogenous and / or continuous structure, e.g., without seams that result from joining different cut pieces together.

[0088] Specifically, a one-piece material and / or unitary structure may be adapted to form a one-piece upper. A one-piece upper may include an upper that essentially includes a one-piece structure. For example, a one-piece upper may include a one-piece base layer, e.g., the base layer may include a one-piece material. A one-piece upper may also include a one-piece base layer of one-piece structure and / or one-piece material onto which additional structural elements may be disposed. For example, a one-piece upper may include a one-piece base layer of one-piece structure and / or one-piece material onto which reinforcing elements may be disposed. In other words, a one-piece upper and / or unitary structure may include no complete layers foreseen in the upper, except for the base layer. For example, the base layer may be the only material that spans the entire upper, and other possible localized reinforcements, e.g., toe reinforcement and / or heel reinforcement, and / or padding, e.g., ankle opening padding, and / or branding may be attached thereto.

[0089] The use of a one-piece material and / or a one-piece structure for the base layer and / or upper may contribute to a minimal and simple structure of the upper. For example, the use of a one-piece material and / or a one-piece structure for the base layer and / or upper may reduce the manufacturing steps and thus the cost of the upper. The use of a one-piece material and / or a one-piece structure for the base layer and / or upper may also contribute to a lightweight, e.g., minimally weighted, and soft upper structure. In particular, the use of a one-piece material and / or a one-piece structure for the base layer and / or upper may allow the upper to fit and / or encase the athlete's foot. Thus, the one-piece material and / or a one-piece structure for the base layer and / or upper may improve the athlete's performance.

[0090] A second aspect of the present invention relates to a shoe, particularly a sports shoe, comprising the above-described upper.

[0091] A shoe including the above upper can have all of the advantageous effects described above with respect to the upper. Generally, the upper may be provided on the shoe so as to be fixed to the midsole of the shoe.

[0093] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. [Brief explanation of the drawings]

[0094] [Figure 1A] 1A-1C are diagrams of an exemplary embodiment of an upper comprising a reinforcing element comprising four reinforcing bands. [Figure 1B] 1A-1C are diagrams of exemplary embodiments of uppers comprising a reinforcing element comprising two reinforcing bands. [Figure 2] 1 is a diagram of a sports shoe with an upper according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0095] In the following, only a few possible embodiments of the present invention will be described in detail, it being understood that these exemplary embodiments can be modified in numerous ways and can be combined with one another where compatible, and that certain features may be omitted insofar as they are not considered essential.

[0096] It should be understood that not all features of the described aspects / embodiments must be present to achieve the technical advantages provided by the present disclosure as defined by the subject matter of the claims. The disclosed aspects / embodiments may be modified by combining specific 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 other aspects / embodiments of the present disclosure, provided that the resulting combination falls within the provisions of the present disclosure.

[0097] Although the following embodiments are primarily described with reference to uppers for sports shoes, such as running shoes, those skilled in the art will recognize that the present disclosure is equally applicable to multiple different technical fields and / or use cases. For example, other sports shoes for basketball, soccer, football, tennis, golf, cross-training, hiking, cycling, trail running, or snowboarding are also contemplated. The expression "sports shoes" refers to sports shoes for athletic use and does not imply use cases that are not directed toward athletics, such as business shoes, chess shoes, or household slippers.

[0098] FIG. 1A shows an exemplary embodiment of an upper 100 according to the present invention. The upper 100 comprises a base layer 110 and a reinforcing element 120. The reinforcing element is disposed on the medial side of the upper 100, e.g., on a side of the upper adapted to face inward when the upper is placed in a shoe. For example, the medial side of the upper 100 may be adapted to directly contact an athlete's foot while wearing the shoe, or to indirectly contact the athlete's foot, e.g., when the athlete is wearing socks. In some embodiments, the reinforcing element 120 may be disposed on the lateral side of the upper 100, e.g., on a side of the upper 100 that is visible when the upper 100 is placed in a shoe. Additionally or alternatively, the reinforcing element 120 may be disposed within the base layer 110. The upper also comprises a plurality of eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g (others not numbered).

[0099] The base layer 110 includes a unidirectionally stretchable material 115. The base layer 100 may be substantially uniformly comprised of the unidirectionally stretchable material 115; for example, the unidirectionally stretchable material 115 may be present essentially throughout the base layer 110. The unidirectionally 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 essentially parallel to the longitudinal direction. Furthermore, the unidirectionally stretchable material 115 is non-stretchable in a second direction 100b. The second direction 100b is essentially perpendicular to the first direction 100a. The second direction 100b includes a component parallel to a direction extending from the lateral side of the upper to the medial side of the upper. In particular, the second direction 100b is essentially parallel to the direction extending from the lateral side to the medial side.

[0100] Generally, the base layer 110 and / or the unidirectionally stretchable material 115 may comprise a woven material. For example, the woven material may include weft and / or warp yarns. Specifically, the weft and / or warp yarns may have different stretch properties. For example, the weft yarns may be more stretchable than the warp yarns. Alternatively, the warp yarns may be more stretchable than the weft yarns. The more stretchable yarns, e.g., the warp and / or weft yarns, may be arranged to run in a first direction 100a. The less stretchable yarns, e.g., the warp and / or weft yarns, may be arranged to run in a second direction 100b. The yarns running in the second direction may be essentially non-stretchable. Additionally or alternatively, the base layer 110 and / or the unidirectionally stretchable material 115 may comprise a knitted material.

[0101] The reinforcing element 120 is formed as a connected and / or continuous reinforcing element 120, e.g., the reinforcing element 120 cannot be broken down into disconnected portions. The reinforcing element 120 comprises four reinforcing bands 125a, 125b, 125c, and 125d. For example, the reinforcing bands 125a and 125b may be associated with lateral portions of the upper 100, and the reinforcing bands 125c and 125d may be associated with a medial portion 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 essentially symmetrically with respect to the medial and lateral portions of the upper 100, as described above. For example, the reinforcing elements 120 are arranged essentially symmetrically with respect to the axis of symmetry 105. The axis of symmetry 105 is based, at least in part, on the medial and lateral portions of the upper 100. For example, the portions of the reinforcing elements 120 arranged on the medial side of the upper 100 have essentially the same shape and size as the portions of the reinforcing elements 120 arranged on the lateral sides of the upper 100. In particular, the portions of the reinforcing elements 120 arranged on the medial side of the upper 100 are essentially mirror images of the portions of the reinforcing elements 120 arranged on the lateral sides of the upper 100 with respect to the axis of symmetry 105.

[0103] Reinforcement band 125a extends from the region associated with eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward region 104 associated with the heel area. Similarly, reinforcement band 125b extends from the region associated with eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward region 102 associated with the midsole and / or Strobel. For example, region 102 associated with the midsole and / or Strobel may constitute a region adapted to contact and / or secured to the midsole and / or Strobel. Additionally, reinforcement band 125d extends from the region associated with eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward region 104 associated with the heel area. Similarly, reinforcement band 125c extends from the region associated with eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g toward region 102 associated with the midsole and / or Strobel. Specifically, the lengths of reinforcement bands 125a, 125b, 125c, and 125d may be greater than the widths of reinforcement bands 125a, 125b, 125c, and 125d. For example, the length of reinforcement band 125a may be greater than the length of reinforcement band 125b.

[0104] Reinforcement bands 125a, 125b associated with the lateral sides of upper 100 may originate at essentially the same eyestays 130e, 130f. Similarly, reinforcement bands 125c, 125d associated with the medial side of upper 100 may originate at essentially the same eyestays (not numbered). In some embodiments, reinforcement bands 125a, 125b associated with the lateral sides of upper 100 may originate at different eyestays. For example, reinforcement band 125b may originate at eyestay 130g, and reinforcement band 125a may originate at eyestay 130d. Specifically, reinforcement bands 125a, 125b may originate at eyestays 130d, 130g associated with the forefoot and / or midfoot regions of the upper.

[0105] The reinforcing element 120 surrounds the eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100. Specifically, the reinforcing element 120 surrounds the eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g as essentially continuous segments. For example, the reinforcing element 120 surrounds all of the eyestays 130a, 130b, 130c, 130d, 130e, 130f, and 130g of the upper 100.
