Description

[0001] Shoe with Enhanced Energy Return

[0002] Field of disclosure

[0003] The present invention relates to a shoe comprising an upper and a sole structure.

[0004] Background of the invention

[0005] Cushioning and energy return are important performance parameters of footwear, especially athletic footwear. Many different approaches have been developed to optimize cushioning and energy return. Many of the known approaches focus on energy return plates, such as plates with a specific geometry or shape, or made of a specific material that balances stability and elasticity. Other approaches focus on the sole unit more broadly, using, for example, gel cores or air cushions in the heel area of the shoe to increase the cushioning of the shoe and thus reduce the strain on the wearer's musculoskeletal system. Another strategy explored in the prior art focuses on sole designs that include vertically arranged spring elements in the heel area. When walking, the sole typically makes initial contact with the ground in the heel area. The vertical spring elements are compressed under the influence of the wearer's weight and are released when the foot pushes off the ground.

[0006] The prior art approaches to energy return suffer from a number of disadvantages. In particular, the efficiency of the energy return is low, i.e. , only a fraction of the energy of a heel strike can be returned. In addition, many energy return devices in the prior art suffer from an unbalanced distribution of energy return across the surface of the shoe. For example, during treading, different areas of the sole experience different pressure profiles, and these different pressure profiles should ideally be accommodated by the energy return unit.

[0007] Another drawback is that the energy return properties of existing shoes are not maintained over time. In particular, it is challenging to maintain high energy return over time and to maintain a balanced distribution of energy return over the surface of the shoe over time. In addition, conventional shoes suffer from poor stability of the wearer's foot. Many known shoes also suffer from an unnatural tread profile.

[0008] Another limitation is imposed by regulatory requirements, particularly in the area of competitive running shoes. For example, the IAAF stack height regulation limits the amount of foam under the foot, which in turn makes efficient energy return and propulsion even more challenging.

[0009] As a result, there is a need to provide shoes with improved energy return and cushioning.

[0010] Summary of disclosure

[0011] It is therefore a general object of the present disclosure to advance the state of the art with respect to shoes with energy return units. In particular, it is an object to provide a shoe that addresses at least some of the disadvantages of the prior art. In at least some variants, it is an object to provide a shoe having high energy return efficiency and / or efficient cushioning. Further, it is an object of at least some variants to provide a shoe that is compliant with relevant regulations in the field of competitive running shoes, in particular with the IAAF stack height regulations. In at least some variants, it is also an object to provide a shoe having a balanced distribution of energy return across the surface of the shoe. Furthermore, it is an object of at least some variants to provide a shoe whose manufacturing may be integrated and implemented into known manufacturing processes.

[0012] The general object is achieved by the subject-matter of the independent claim. Further advantageous embodiments follow from the dependent claims and the overall disclosure.

[0013] A first aspect of the present disclosure relates to a shoe comprising an upper and a sole structure. The sole structure comprises a base element arranged in a vertical direction at least partially underneath the upper. The sole structure further comprises a rim plate arranged peripherally on an outer contour of the upper and in the vertical direction at least partially above the base element. The sole structure further comprises an elastic damping element operatively connected to the rim plate and arranged in the vertical direction underneath the rim plate, wherein the elastic damping element is configured to absorb the force of a tread impulse by elastic deformation and to subsequently release at least a portion of the absorbed force to the rim plate. The sole structure further comprises at least one tension member for force transmission between the base element and the rim plate.

[0014] By providing the rim plate and the elastic damping element, the energy return of the shoe is greatly improved. As an illustration, the force of a tread impulse may be absorbed by elastic deformation of the elastic damping element. Because the elastic damping element is operatively connected to the rim plate, the energy that is returned when the elastic damping element returns to its original shape is transmitted to the rim plate. From the rim plate, the returned energy may in turn be transmitted to the base element through the tension members, ultimately contributing to forward propulsion of the foot of the wearer.

[0015] Because the rim plate is arranged peripherally on an outer contour of the upper, the design space available for damping elements is greatly increased. For example, the damping element need not be limited in its volume to an area underneath the wearer’s foot, but can also extend beyond their area. For example, the rim plate may in some variants extend circumferentially around the upper, which allows the elastic damping element to have a total surface area in contact with the ground that exceeds the surface area of the wearer’s foot significantly.

[0016] Directional indications as used in the present disclosure are to be understood as follows: The longitudinal direction LO of the sole structure, respectively the shoe, is described by an axis from the heel area, respectively from the heel edge, to the forefoot area, respectively to the shoe tip / toe tip, and thus extends along the longitudinal axis of the sole structure or shoe. Thus the term “extending along / in the longitudinal direction” typically refers to extending towards the shoe tip, respectively toe tip, and the term “extending against the longitudinal direction” typically refers to extending towards the heel edge. The transverse direction TR of the sole plate unit respectively the shoe sole, extends transversely to the longitudinal axis and substantially parallel to the ground in the operative state. Thus, the transverse direction runs along a transverse axis of the sole structure, respectively the shoe. In the context of the present disclosure, the vertical direction V denotes a direction from a base layer to a top layer of the base element, or in the operative state in the direction of the foot of the wearer, and thus runs along a vertical axis of the sole structure, respectively the shoe. Thus the term “extending along / in the vertical direction” typically refers to extending towards the top layer of the base element, and the term “extending against the vertical direction” typically refers to extending towards the base layer of the base element. The longitudinal direction, the vertical direction and the transverse direction may all be perpendicular to each other. The indication “horizontal” refers to a plane extending in the longitudinal and the transverse direction and being perpendicular to the vertical direction. The lateral side of the sole plate unit, respectively the sole, is the outer perimeter of the sole structure, respectively the shoe, between the heel edge and the shoe tip / toe tip, which in the worn state rests against the outer instep of the wearer's foot. The medial side of the sole structure, respectively the shoe, refers to the inner perimeter of the sole structure, respectively the shoe, between the heel edge and the shoe tip / toe tip, which is located opposite the lateral side. Thus, in a pair of worn running shoes, the medial sides of the two running shoes face each other and the lateral sides face away from each other. Furthermore, the sole structure, respectively the shoe, may typically along the longitudinal direction be divided into a forefoot area, a heel area and a midfoot area being arranged between the forefoot area and the heel area. For example, the forefoot area extends from the shoe tip against, i.e. opposite, the longitudinal direction to 30-45% of the total length of the sole plate unit, respectively the sole, in the longitudinal direction. The heel area extends, for example, from the heel edge in the longitudinal direction to 20-30% of the total length of the sole plate unit, respectively the sole in the longitudinal direction. The midfoot area extends directly between the heel area and the forefoot area, such that the length in the longitudinal direction of the midfoot area makes up the remaining portion of the total length, particularly from 15-50% of the total length.

[0017] In the vertical direction, the top layer is typically arranged above the base layer. Furthermore at least at some positions, the top layer is in the vertical direction spaced apart from the base layer thereby defining the compartment. However, this does not necessarily mean that the top layer and the base layer are arranged in the transverse direction directly above each other, i.e. that they are in the transverse direction aligned. It is also possible that in the transverse direction, the top layer and the base layer may be completely or partially offset to each other. For example, the top layer may be arranged in the center of the sole plate unit, while the base layer may be medially and laterally offset to the center top layer.

[0018] The upper as used herein is configured for receiving the foot of a wearer and for securing the foot to the shoe. Typically, the sole structure is at least partially arranged in the vertical direction underneath the upper. For example, the base element of the sole structure is typically arranged in the vertical direction underneath the upper, while the rim plate is arranged peripherally on an outer contour of the upper. Typically, the base element is arranged in the vertical direction directly underneath the foot of a wearer. Typically, the base element is arranged to be underneath a sole of a foot of a wearer wearing the shoe. For example, while the base element may in the vertical direction be arranged underneath the upper, the base element may in the longitudinal direction and in the transversal direction overlap, e.g. coincide with, a lower delimitation of the upper. For example, in some variants, the base element is arranged in the vertical direction adjacent to a lower delimitation of the upper or in the vertical direction adjacent to an insole or the base element constitutes a lower delimitation of the upper. The lower delimitation of the upper may for example be a lower surface of the upper. Lower, in this context, means that the delimitation is arranged in the vertical direction towards the ground.

[0019] Depending on the application, different rim plates may be used. For example, the rim plate may in some variants be least partially arranged in a forefoot area of the sole structure. Alternatively or in combination, the rim plate may at least partially be arranged in a midfoot area of the shoe. Alternatively or in combination, the rim plate may at least partially be arranged in a heel area of the shoe. In some variants, the rim plate extends across the forefoot area, the midfoot area and the heel area of the sole structure.

[0020] Depending on the application, the rim plate may be made of different materials. In some variants, the rim plate is an integrally formed rim plate, i.e. it is a single piece. In some variants, the rim plate comprises at least two separate pieces, e.g. a medial piece and a lateral piece.

[0021] In some variants, the rim plate is at least partially made of the continuous material and / or a through-going material. In some variants, the rim plate is at least partially made of a latticed or grid-like material. The rim plate may optionally comprise a lacing system, for example openings or apertures for receiving a lacing.

[0022] Typically, the hardness of the rim plate is between a Vickers Hardness (HV) 50 HV and 125 HV in particular between 75 HV and 100 HV (see for example Ghani et al “Hardness, Tensile and Microstructure Assessment of Carbon / Glass Hybrid Composite Laminate” J. Mechanical Engineering 2018, 15(2), 91-105). In some embodiments, the hardness of the rim plate is greater than the hardness of the elastic damping element. In some variants, the rim plate has a higher flexural modulus than the elastic damping element.

[0023] In some embodiments, the rim plate has anisotropic bending characteristics. In further embodiments, the rim plate has isotropic bending characteristics.

[0024] In some embodiments, the rim plate is made from polymeric materials, such as polyamide, polyether block amide (PEBAX), polyurethane. In certain embodiments, the rim plate comprises fiber materials, such as glass fibers or carbon fibers. Preferably, the base element and / or the rim plate may be made of carbon fiber.

[0025] In some variants, the rim plate and the base element are separately formed. In some variants, the rim plate and the base element are integrally formed, i.e. they are a single piece. For example, the base element and the rim plate may be connected to each other through a connection plate. The connection plate typically extends in the vertical direction. The connection plate may for example be made of the same material as the rim plate. Alternatively or in combination, the connection plate maybe made of the same material as the base element. The rim plate is in the vertical direction arranged at least partially above the base element. Above, in this context, means in a direction facing away from the ground. In some variants, the rim plate is arranged fully above the base element in the vertical direction. In some variants, the rim plate is at least in the heel area and or in the midfoot area arranged in the vertical direction at least partially above the base element. Alternatively or in combination, the rim plate may at least in the forefoot area be arranged at least partially above the base element in the vertical direction. Alternatively or in combination, the rim plate may in the forefoot area be arranged at least partially below the base element in the vertical direction. For example, a portion of the rim plate may in the forefoot area be arranged below the base element in the vertical direction, and another portion of the rim plate may in the forefoot area be arranged above the base element in the vertical direction. More generally, in some variants, at least a portion of the rim plate is in the vertical direction arranged above the base element, and another portion of the rim plate is in the vertical direction arranged below the base element. In some variants, a maximum distance in the vertical direction between the rim plate and the base element may for example be at least 5 mm, for example from 5 mm to 50 mm, such as from 5 mm to 40 mm, particularly from 7 mm to 20 mm.

[0026] The relative positioning of the rim plate with respect to the base element allows fine-tuning of the energy return properties of the shoe. For example a certain inclination of the rim plate with respect to the base element may be used to improve forward propulsion on takeoff.

[0027] Depending on the application, the rim plate may for example encompass the upper partially or even fully. In some variants, the rim plate is arranged on a circumferential segment of the upper for example, the rim plate may extend across that circumferential segment. In some variants, the rim plate is arranged circumferentially around the upper. In other words, the rim plate may circumferentially encompass the upper. The rim plate may circumferentially encompass the upper in an intermittent or in a continuous fashion.

[0028] Depending on the application, the rim plate may have different geometries. For example, the rim plate may have a width from 5 mm to 50 mm, preferably from 10 mm to 25 mm. The width of the rim plate typically relates to a width of the rim plate in horizontal direction. Depending on the application, the width of the rim plate may be different between the lateral side and the medial side, or it may be essentially the same. For example, the rim plate may have a medial width from 5 mm to 40 mm, preferably from 10 mm to 20 mm, more preferably of 15 mm. Alternatively or in combination, the rim plate may have a lateral width from 10 mm to 50 mm, preferably from 15 mm to 25 mm, more preferably of 20 mm. the width of the rim plate may, for example, be defined as a distance between an outer edge of the rim plate and an inner edge of the rim plate.

[0029] In some variants, the rim plate has a thickness from 1 mm to 25 mm, preferably from 1.5 mm to 10 mm, more preferably from 2 mm to 7 mm. The thickness of the rim plate typically relates to the extension in vertical direction. It is understood that when the rim plate is for example angled or tilted with respect to the horizontal plane, the axis along which the thickness is measured is also angled or tilted to the same extent and in the same direction.

[0030] The rim plate is arranged peripherally on an outer contour of the upper. Depending on the application, the rim plate may be directly or indirectly connected to the upper. For example, in some variants, the rim plate is welded to the upper or connected to the upper through an adhesive, such as a sprayed adhesive. In some variants, the rim plate may be heat bonded to the upper.

[0031] Depending on the application, the rim plate may or may not be angled. The rim plate may optionally be angled in different directions. For example, the rim plate may be angled with respect to a radial direction, i.e. an outward extension parallel to the horizontal plane. In some variants, at least a portion of a medial segment of the rim plate may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 70° to 110°, preferably from 85° to 95°, more preferably 90°. The respective portion of the medial segment that extends radially at the respective angle a may for example comprise a heel portion of the medial segment of the rim plate, a midfoot portion of the medial segment of the rim plate and / or a forefoot portion of the medial segment of the rim plate. For example, in some variants, at least a midfoot portion of the medial segment of the rim plate (and optionally additionally a heel portion of the medial segment of the rim plate) may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 70° to 110°, preferably from 85° to 95°, more preferably 90°.

[0032] Alternatively or in combination, the variants may also apply to the lateral side of the shoe. Thus, in some variants, at least a portion of a lateral segment of the rim plate may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 70° to 110°, preferably from 85° to 95°, more preferably 90°. The respective portion of the lateral segment that extends radially at the respective angle a may for example comprise a heel portion of the lateral segment of the rim plate, a midfoot portion of the lateral segment of the rim plate and / or a forefoot portion of the lateral segment of the rim plate. For example, in some variants, at least a midfoot portion of the lateral segment of the rim plate (and optionally additionally a heel portion of the lateral segment of the rim plate) may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 70° to 110°, preferably from 85° to 95°, more preferably 90°.

[0033] It is understood that the angle a is measured with respect to the vertical direction. For example, an angle a of 90° corresponds to a radial extension in parallel to the horizontal direction.

[0034] Depending on the application, an angle of the rim plate with respect to the radial direction may or may not differ for different segments of the rim plate, or even for different portions of the segments of the rim plate. For example, in some variants, a heel segment of the rim plate may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 70° to 110°, preferably from 85° to 95°, more preferably 90°. Typically, the heel segment of the rim plate extends radially away from the heel edge and essentially along the longitudinal direction. For example, the heel segment of the rim plate may on one side be adjacent to the lateral segment of the rim plate, specifically the heel portion of the lateral segment of the rim plate, and on the another side be adjacent to the medial segment of the rim plate, specifically the heel portion of the medial segment of the rim plate.

[0035] Depending on the application, the segment or portion of the rim plate arranged in the forefoot area may optionally have a different angle. For example, in some variants, a forefoot segment of the rim plate may extend radially from an inner edge of the rim plate to an outer edge of the rim plate at an angle a with respect to the vertical direction from 30° to 100 °, preferably from 45° to 90°, more preferably from 45° to 75°. In other words, the forefoot segment of the rim plate may be described to be inclined upwards from an inner edge of the rim plate to an outer edge of the rim plate. Typically, the forefoot segment of the rim plate extends radially away from the shoe tip / toe tip and essentially along the longitudinal direction. For example, the forefoot segment of the rim plate may on one side be adjacent to the lateral segment of the rim plate, specifically the forefoot portion of the lateral segment of the rim plate, and on the another side be adjacent to the medial segment of the rim plate, specifically the forefoot portion of the medial segment of the rim plate.

[0036] In addition to the variants described above, the lateral segment of the rim plate and / or the medial segment of the rim plate may also be angled with respect to the longitudinal direction. For example, in some variants, at least a midfoot portion of the lateral segment of the rim plate is inclined with respect to the longitudinal direction. Alternatively or in combination, in some variants, at least a midfoot portion of the medial segment of the rim plate is inclined with respect to the longitudinal direction. In some variants, for example, a heel portion of the lateral segment of the rim plate may (optionally additionally) be inclined with respect to the longitudinal direction. Alternatively or in combination, in some variants, a heel portion of the medial segment of the rim plate may (optionally additionally) be inclined with respect to the longitudinal direction. In the embodiments described in this paragraph, the respective portions of the rim plate are preferably inclined such that a front end of the respective portion, which front end faces the toe tip, is arranged in the vertical direction below (i.e. closer to the ground during operation) a rear end of the respective portion, which rear end faces the heel edge. However, depending on the application, other inclinations may be used as well. To quantify the inclination with respect to the longitudinal direction, a longitudinal inclination angle p may be defined as an angle between the respective segment of the rim plate and the longitudinal direction, respectively the horizontal plane. In some variants, at least the midfoot portion of the lateral segment of the rim plate and / or at least a midfoot portion of the medial segment of the rim plate have a longitudinal inclination angle from 5° to 45°, preferably from 5° to 30°, with respect to the longitudinal direction. For example, in some variants, the midfoot portion of the lateral segment of the rim plate and the heel portion of the lateral segment of the rim plate independently have a longitudinal inclination angle p from 5° to 45°, preferably from 5° to 30°, with respect to the longitudinal direction. Alternatively or in combination, in some variants, the midfoot portion of the medial segment of the rim plate and the heel portion of the medial segment of the rim plate independently have a longitudinal inclination angle p from 5° to 45°, preferably from 5° to 30°, with respect to the longitudinal direction. Independently, in this context, means that the longitudinal inclination angle of the two portions are chosen independently of each other, and that the longitudinal inclination angle for each section is chosen independently of that of each other section.

[0037] The positive sign of the longitudinal inclination angle p is not to be interpreted as an indication of the direction of inclination. For example, when the midfoot portion of the lateral segment has a longitudinal inclination angle p of for example +5°, the midfoot portion of the lateral segment may be inclined upwards or downwards

[0038] In some variants, at least the midfoot portion of the lateral segment of the rim plate (and optionally additionally the heel portion of the lateral segment of the rim plate) is typically inclined such that a rear end of the midfoot portion of the lateral segment of the rim plate is arranged in vertical direction above, i.e. higher than (i.e. further from the ground than), a front end of the midfoot portion of the lateral segment of the rim plate. The rear end of the midfoot portion of the lateral segment of the rim plate faces the heel edge, while the front end of the midfoot portion of the lateral segment of the rim plate faces the toe tip. Similarly, if the midfoot portion and the heel portion of the lateral segment of the rim plate are both inclined, they may be inclined such that a rear end of the heel portion of the lateral segment of the rim plate may be arranged in vertical direction above, i.e. higher than (i.e. further from the ground than), a front end of the midfoot portion of the lateral segment of the rim plate.

[0039] Alternatively or in combination, at least the midfoot portion of the medial segment of the rim plate (and optionally additionally the heel portion of the medial segment of the rim plate) is typically inclined such that a rear end of the midfoot portion of the medial segment of the rim plate is arranged in vertical direction above, i.e. higher than (i.e. further from the ground than), a front end of the midfoot portion of the medial segment of the rim plate. The rear end of the midfoot portion of the medial segment of the rim plate faces the heel edge, while the front end of the midfoot portion of the medial segment of the rim plate faces the toe tip. Similarly, if the midfoot portion and the heel portion of the medial segment of the rim plate are both inclined, they may be inclined such that a rear end of the heel portion of the medial segment of the rim plate may be arranged in vertical direction above, i.e. higher than (i.e. further from the ground than), a front end of the midfoot portion of the medial segment of the rim plate.

[0040] In some variants, at least the midfoot portion of the lateral segment of the rim plate has an inclination height difference from 3 mm to 55 mm, preferably from 10 mm to 40 mm. Alternatively or combination, at least the midfoot portion of the medial segment of the rim plate may have an inclination height difference from 3 mm to 55 mm, preferably from 10 mm to 40 mm. The inclination height difference of e.g. the midfoot portion of the lateral segment of the rim plate is defined as the difference in the vertical direction between vertical position of the rear end of the midfoot portion of the lateral segment of the rim plate and the front end of the midfoot portion of the lateral segment of the rim plate. Similarly, the inclination height difference of e.g. the midfoot portion of the medial segment of the rim plate is defined as the difference in the vertical direction between the vertical position of the rear end of the midfoot portion of the medial segment of the rim plate and the front end of the midfoot portion of the medial segment of the rim plate.

[0041] Depending on the application, the forefoot portions of the rim plate may or may not be inclined. In some variants, at least a forefoot portion of the medial segment of the rim plate is inclined with respect to the longitudinal direction. Alternatively or in combination, in some variants, at least a forefoot portion of the lateral segment of the rim plate is inclined with respect to the longitudinal direction. In the embodiments described in this paragraph, the respective portions of the rim plate (i.e. the forefoot portion of the medial segment of the rim plate and the forefoot portion of the lateral segment of the rim plate) are preferably inclined such that a front end of the respective portion, which front and faces the toe tip, is arranged in the vertical direction above (i.e. further from the ground during operation) a rear end of the respective portion, which rear end faces the heel edge. However, depending on the application, other inclinations may be used as well.

[0042] Depending on the application, the forefoot portion of the medial segment of the rim plate and / or the forefoot portion of the lateral segment of the rim plate may have different longitudinal inclination angles p. For example, in some variants, the forefoot portion of the medial segment of the rim plate has a longitudinal inclination angle from 10° to 70°, preferably from 10° to 45°, with respect to the longitudinal direction. Alternatively or in combination, in some variants, a forefoot portion of the lateral segment of the rim plate has a longitudinal inclination angle p from 10° to 70°, preferably from 10° to 45°, with respect to the longitudinal direction.

[0043] In some variants, the forefoot portion of the lateral segment of the rim plate has an inclination height difference from 3 mm to 55 mm, preferably from 15 mm to 40 mm. Alternatively or in combination, the forefoot portion of the medial segment of the rim plate may have an inclination height difference from 3 mm to 55 mm, preferably from 15 mm to 40 mm.

[0044] Different combinations of inclination profiles of the different portions of the rim plate are possible. In a preferred embodiment, the midfoot portion of the lateral segment of the rim plate and the midfoot portion of the medial segment of the rim plate are inclined in a descending manner. Alternatively or in combination, in some variants, the forefoot portion of the lateral segment of the rim plate and the forefoot portion of the medial segment of the rim plate are inclined in an ascending manner. Ascending, in this context, means that the rear end of the respective midfoot portion (i.e. the midfoot portion of the lateral segment of the rim plate and the midfoot portion of the medial segment of the rim plate) is arranged in the vertical direction below (i.e. closer to the ground during operation) a front end of the respective midfoot portion. Descending, in this context, means that the front end of the respective forefoot portion (i.e. the forefoot portion of the lateral segment of the rim plate and the forefoot portion of the medial segment of the rim plate) is arranged in the vertical direction below (i.e. closer to the ground during operation) a rear end of the respective forefoot portion.

[0045] For the different variants relating to longitudinal inclination of the rim plate that are described herein, different inclination profiles may be used. For example, a given portion or segment of the rim plate may be inclined evenly or unevenly. For example, if a given portion or segment of the rim plate is inclined evenly, a cross section of the respective portion or segment along the vertical direction and along the longitudinal direction may typically be an essentially straight line. In a further example, if a given portion or segment of the rim plate is inclined unevenly, a cross-section of the respective portion segment along the vertical direction and along the longitudinal direction may for example be curved. For example, the degree of inclination may gradually increase or decrease, depending on the application.

[0046] Depending on the application, different base elements may be used. In some variants, the base element is a base plate. In some variants, the base plate is a rigid base plate. Typically, the hardness of the base plate may be between a Vickers Hardness (HV) 50 HV and 125 HV in particular between 75 HV and 100 HV (see for example Ghani et al “Hardness, Tensile and Microstructure Assessment of Carbon / Glass Hybrid Composite Laminate” J. Mechanical Engineering 2018, 15(2), 91-105). In some embodiments, the hardness of the base plate is greater than the hardness of the elastic damping element. In some embodiments, the base element (e.g. the base plate) has anisotropic bending characteristics.

[0047] In some embodiments, the base plate is made from polymeric materials, such as polyamide, polyether block amide (PEBAX), polyurethane. In certain embodiments, the base plate comprises fiber materials, such as glass fibers or carbon fibers. In some variants, the base plate is made of carbon fibers.

[0048] In a typical embodiment, the base plate is configured for absorbing the forces that occur during walking, particularly during running. The forces occurring during walking, preferably during running, may in some variants relate to a runner having a bodyweight from 40 kg to 150 kg, preferably from 50 kg to 90 kg.

[0049] In some variants, the base element (e.g. the base plate) is at least partially made of a continuous material and / or a through-going material. In some variants, the base element (e.g. the base plate) is at least partially made of a latticed or grid-like material. For example, latticed or grid-like material may be used to balance weight and stability.

[0050] The elastic damping element is configured to absorb the force of a tread impulse by elastic deformation and to subsequently release at least a portion of the absorbed force to the rim plate. For example, when the elastic damping element returns to its original shape after elastic deformation, at least the portion of the absorbed force may be released to the rim plate. Preferably, the elastic damping element is configured to return at least 50%, in particular at least 70%, of the force of the tread impulse.

[0051] Thus, the elastic damping element (and the shoe more broadly) may be described in the context of an uncompressed state and a compressed state. In the compressed state, the elastic damping element is elastically deformed at least partially. The compressed state is typically adopted during absorption of the tread impulse, i.e. when the runner hits the ground. In the uncompressed state, the elastic damping element is essentially undeformed. The uncompressed state is typically adopted after the runner has lifted the shoe of the ground. It is understood that the embodiments described herein generally refer to the uncompressed state, unless otherwise indicated or unless the context dictates otherwise.

[0052] Depending on the application, different elastic damping element may be used. In some variants, the elastic damping element comprises a foam, such as a polymer foam. For example, in some variants the elastic damping element is made of a foam, such as a polymer foam. For example, in some variants, the elastic damping element may comprise or consist of: polyurethanes, in particular expanded polyurethane, polyethers, polyethylenes, polyamides, polyvinyl acetates, polyether block amides, polyethylene vinyl acetate (EVA), polyolefins, polyesters, or mixtures, e.g. copolymers such as copolymers, thereof. Preferably, the elastic damping element may be made of pebax®.

[0053] Depending on the application, the elastic damping element may optionally comprise one or more springs, such as springs made of carbon fibers. Alternatively or in combination, the elastic damping element made some variants comprise damping additives, such as a damping gel and / or a damping liquid. The damping additives may for example be embedded in a foam, such as a polymer foam.

[0054] In some variants, the elastic damping element may comprise an inner damping portion and an outer damping portion. Depending on the application, the inner damping portion may in the vertical direction be arranged underneath the upper. Preferably an outer contour of the inner damping portion is flush in the vertical direction with the outer contour of the upper. In other words, a given point on the outer contour of the inner damping portion may in some variants not extend beyond a given point on the outer contour of the upper arranged in the vertical direction above the given point of the outer contour of the inner damping portion. The outer damping portion may, for example, be arranged peripherally on the outer contour of the inner damping portion. For example, the outer damping portion may at least partially, preferentially fully, circumferentially encompass the inner damping portion. In a typical embodiment, the height of the inner damping portion, i.e. the maximum extension of the inner damping portion in the vertical direction, is limited by the upper. However, in at least some variants, the height of the outer damping portion, i.e. the maximum extension of the outer damping portion in the vertical direction, may be higher than the height of the inner damping portion. The increased height may for example be used to increase energy return and cushioning. The elastic damping element may at least partially be arranged peripherally on an outer contour of the upper. For example, the elastic damping element may be directly or indirectly interconnected to the outer contour of the upper. As an example, in some variants, the elastic damping element contacts the outer contour of the upper. In some variants, an upper portion of the elastic damping element is arranged circumferentially around the upper and preferably directly contacts the upper. The upper portion of the elastic damping element may, for example, be comprised by the outer damping portion. For example, the outer damping portion may in some variants comprise the upper portion of the elastic damping element, as well as a lower outer portion of the elastic damping element. In these variants, the inner damping portion may, for example, be labelled as lower inner portion of the elastic damping element.

[0055] In a typical embodiment, the different portions of the elastic damping element are integrally formed, i.e. made of a single piece. In other words, the distinction between different portions main some variants be merely terminological, but may not be reflective of the physical nature of the elastic damping element. However, it is also possible that the elastic damping element may be made of two or more pieces.

[0056] Typically, the elastic damping element extends from a ground-facing surface (which may e.g. be a ground-contacting surface or which may be configured to face to an outsole) to a rim-facing surface (which may e.g. be a rim-contacting surface). In some variants, the inner damping portion extends in the vertical direction from a ground-facing surface to an upperfacing surface (e.g. an upper-contacting surface) of the inner damping portion. In some variants, the outer damping portion extends in the vertical direction to a rim-facing surface (e.g. rim-contacting surface). For example, the outer damping portion may extend from a ground-facing surface (e.g. a ground-contacting surface) to the rim-facing surface (e.g. rimcontacting surface) of the outer damping portion. It is also conceivable that the outer damping portion may not, or at least only partially, contact the ground.

[0057] Depending on the application, the elastic damping element may have different shapes. The shape of the damping element may, for example, be used to fine-tune or optimize the energy-return properties of the shoe. In some variants, at least a circumferential segment of an outer contour of the elastic damping element forms at least one outwardly extending bulge. For example, the at least one outwardly extending bulge may in some variants have a maximum extension in radial direction from 3 mm to 30 mm, preferably from 5 mm to 15 mm, with respect to a respective base surface adjacent to the respective outwardly extending bulge. In other words, the at least one outwardly extending bulge may be described to have a bulge rise from 3 mm to 30 mm, preferably from 5 mm to 15 mm. The radial direction is arranged parallel to the horizontal plane.

[0058] Depending on the application, an outer contour of the elastic damping element may at least partially be convex, concave, or essentially planar. It is also possible, in some variants, that different portions of the elastic damping element have differently shaped outer contours. In some variants, in a cross-section parallel to the vertical direction and orthogonal to a longitudinal direction of the shoe, at least a longitudinal section of the elastic damping element having a length in longitudinal direction of at least 25 mm (preferably at least 50 mm) may have a convex medial outer contour and / or a convex lateral outer contour. The longitudinal section having a length in longitudinal direction of at least 25 mm (preferably at least 50 mm) may, for example, be selected from one or more of: a heel area, a midfoot area and a forefoot area. Thus, in some variants, at least a midfoot section of the elastic damping element (and optionally additionally a forefoot section and / or a heel section of the elastic damping element) has a convex medial outer contour and / or a convex lateral outer contour in a cross-section parallel to the vertical direction and orthogonal to the longitudinal direction of the shoe. In some variants, the entire elastic damping element has a convex outer contour. Depending on the application, the degree of convexness may change along the circumference of the elastic damping element, or it may remain essentially unchanged along the circumference of the elastic damping element.

[0059] In some variants, an outer ridgeline of the convex medial outer contour of the respective longitudinal section of the elastic damping element and / or an outer ridgeline of the convex lateral outer contour of the respective longitudinal section of the elastic damping element is arranged closer in the vertical direction to a ground-facing surface of the elastic damping element than to a rim-facing surface of the elastic damping element. In other words, the outer ridgeline of the convex medial outer contour and / or an outer ridgeline of the convex lateral outer contour of the respective longitudinal section may be described to be arranged in the vertical direction in the lower half of the elastic damping element. The lower half of the elastic damping element is arranged opposite an upper half of the elastic damping element, which upper half faces the rim plate. In some embodiments, the outer ridgeline of the convex medial outer contour and / or an outer ridgeline of the convex lateral outer contour of the respective longitudinal section is arranged in the vertical direction within 50 mm from the ground-contacting surface, preferably within a range from 15 mm to 45 mm, more preferably from 25 mm to 40 mm.

[0060] The outer ridgeline of the convex medial outer contour as used herein is defined as the line on the medial outer contour of the elastic damping element that extends in longitudinal direction and has a maximum outward extension in the radial direction. Similarly, the outer ridgeline of the convex lateral outer contour as used herein is defined as the line on the lateral outer contour of the elastic damping element that extends in longitudinal direction and has a maximum outward extension in the radial direction.

[0061] Depending on the application, the elastic damping element may have different geometrical extensions. For example, an inner damping portion of the elastic damping element may have a height in vertical direction of up to 30 mm, preferably up to 20 mm. The height of the inner damping at portion may, for example, be chosen in accordance with relevant regulations, such as maximum stack height regulations for competitive running. In some variants, the outer damping portion of the elastic damping element may have a height in vertical direction exceeding the height of the inner damping portion. In some variants, the outer damping portion of the elastic damping element has a height in vertical direction of at least 20 mm, preferably from 30 mm to 100 mm, more preferably from 40 mm to 80 mm.

[0062] The height of the elastic damping element may be essentially the same across the different areas of the shoe, or it may differ for different areas of the shoe. In some variants, at least in a heel area and / or in a midfoot area of the shoe, the elastic damping element has a height in the vertical direction from 40 mm to 100 mm, preferably from 50 mm to 80 mm.

[0063] The at least one tension member is configured for force transmission between the base element and the rim plate. To this end, the at least one tension member typically interconnects the base element and the rim plate. Depending on the application, the sole structure may comprise multiple tension members.

[0064] In some variants, the at least one tension member is integrally formed with the base element and / or integrally formed with the rim plate. In some variants, the at least one tension member and the base element are separate pieces. Alternatively or in combination, the at least one tension member and the rim plate may be separate pieces.

[0065] Depending on the application, the at least one tension member may be made of different materials. Typically, the at least one tension members made of a tension-resistant material. For example, the tension member may in some variants have an ultimate tensile strength of at least 30 MPa, preferably at least 100 MPa, more preferably at least 500 MPa, even more preferably at least 1’000 MPa, even more preferably at least 1’500 MPa, even more preferably at least 2’000 MPa. In some variants, the tension member has an ultimate tensile strength from 2’000 MPa to 3’500 MPa. In some variants, the at least one tension member is made of a rigid material. For example, the at least one tension member may be made of carbon fibers. In some variants, the at least one tension member is made of a flexible material. For example, the at least one tension member may comprise or consist of a textile material. In some variants, the at least one tension member is made of polyethylene, e.g. ultra high molecular weight polyethylene such as dyneema. In some variants, the at least one tension member may comprise both a rigid material and a flexible material, such as a textile material. The rigid material may, for example, be used for reinforcement and / or structural rigidity. In some variants, the at least one tension member interconnects the base element and the rim plate in a tension-resistant fashion. For example, the at least one tension member may be connected to the rim plate and / or to the base element through an adhesive.

[0066] The at least one tension member may interconnect the base element and the rim plate in different ways. For example, the sole structure may comprise a plurality of tension members, each of which may for example comprise a strap, a tape, strip, or a tie interconnecting the base element and the rim plate. The tension members of the plurality of tension members may, for example, be arranged equidistally leave with respect to each other. However, the tension members may optionally also be concentrated in certain areas of the shoe experiencing high tensile forces.

[0067] In some variants, the sole structure comprises at least one tension member arranged at least partially in the forefoot area. Alternatively or in combination, the sole structure may comprise at least one tension member arranged at least partially in the heel area. Alternatively or in combination, sole structure may comprise at least one tension member arranged at least partially in the midfoot area. For example, the sole structure may comprise at least one tension member extending across the heel area, the midfoot area and the forefoot area. For example, in some variants, the at least one tension member is at least partially, preferably fully, arranged circumferentially around the upper. For example, at least a portion of the at least one tension member may circumferentially surround the upper partially or fully. Depending on the application, the tension member may be made of a through-going material or it may be made of a latticed or grid-like material.

[0075] Exemplary embodiments

[0076] Figures 1a and 1b show an embodiment of a shoe 1 disclosed herein. The shoe 1 is shown from a rear view in an uncompressed state (Fig. 1A) and in a compressed state (Fig. 1 B). The compressed state results from absorption of the force of a tread impulse during the gait cycle of the wearer in use. The shoe 1 comprises an upper 2 and a sole structure 3. The sole structure 3 in turn comprises a base element 4, which in the illustrated embodiment is a base plate 4. The base plate 4 is arranged underneath the upper, more specifically underneath the wearer’s foot. In the illustrated embodiment, the base element 4 is made of a rigid material.

[0077] The base plate 4 is interconnected through a tension member 7 with a rim plate 5. The rim plate 5 is arranged in the vertical direction above the base plate 4. The rim plate 5 is also arranged circumferentially around the upper 2. In the embodiment illustrated in figure 1, the base plate 4, the tension member 7 and the rim plate 5 are integrally formed. The rim plate

[0078] 5 extends along a medial side and along a lateral side of the upper 2. Thus, the rim plate 5 comprises a lateral segment 51 and a medial segment 52.

[0079] The sole structure 3 further comprises an elastic damping element 6, which in the illustrated embodiment is made of a foam. The elastic damping element 6 is arranged in the vertical direction underneath both the rim plate 5 and underneath the base plate 4. In the longitudinal direction and in a transversal direction (which is orthogonal to the longitudinal direction and orthogonal to the vertical direction), the elastic damping element 6 extends to both the base plate 6 and to the rim plate 5. More specifically, a section of the elastic damping element 6 is arranged directly underneath the rim plate 6 and contacts the rim plate 6 with a rim-facing surface, and another section of the elastic damping element 6 is arranged directly underneath the base plate 4 and contacts the base plate 4. Furthermore, the volume between the bottom of the foot of the wearer (or alternatively an insole) and the base element 4 may optionally be occupied at least partially by a second elastic damping element, e.g. a foam.

[0080] During a tread impulse of a wearer of the shoe, the tread impulse is transferred to the elastic damping element 6, which as a result of the tread impulse is elastically deformed, thereby absorbing the force of the tread impulse. During take-off of the foot of the wearer, the elastic damping element 6 returns into its original shape, thereby exerting a take-off force onto the foot’s wearer. In the illustrated embodiment shown in figure 1 , the elastic damping element

[0081] 6 is arranged not just underneath the base plate 4, but also underneath the rim plate 5. This allows for a larger volume of foam that can be used, thereby increasing the efficiency of energy return. Furthermore, by having both a base element 4 and a rim plate 6, the energy can be transferred to different portions of the upper and therefore, the distribution of energy return may be improved.

[0082] Figure 1A shows the shoe in an uncompressed state, corresponding to a rest position. In this state, the rim plate 5 has a certain distance h2 in the vertical direction V from the ground, and the base plate 4 has a certain distance hi in the vertical direction V from the ground. Both distance h2 and distance hi are reduced in the compressed state, as shown in figure 1A.

[0083] Figure 2 shows the embodiment shown in figure 1 in further detail. In particular, figure 2 illustrates that the elastic damping element 6 has a convex medial and lateral profile, comprising outwardly extending bulges 61 on the medial side and on the lateral side. The outwardly extending bulges 61 improve the energy return properties of the shoe 1 . An outermost contour of the elastic damping element 6 defines an outer ridgeline of the convex medial outer contour 62 and an outer ridgeline of the convex lateral outer contour 63. The respective outer ridgelines extend circumferentially around the elastic damping element 6. As illustrated in figure 2, the outer ridgeline of the convex medial outer contour 62 and the outer ridgeline of the convex lateral outer contour 63 are each arranged closer in the vertical direction to the ground-facing surface 64 of the elastic damping element 6 than to the rimfacing surface 65 of the elastic damping element 6. In other words, it may be said that the outer ridgeline of the convex medial outer contour 62 and the outer ridgeline of the convex lateral outer contour 63 are both arranged in a lower half of the elastic damping element 6 in the illustrated embodiment.

[0084] Figure 3 shows a further embodiment of the shoe disclosed herein from a rear view (Fig. 3A) and a side view (Fig. 3B). It comprises a rim plate 5 and a base plate 4 which are made of two distinct pieces. They are interconnected to each other through a tension member 7, which in the illustrated embodiment is made of a tensile-resistant textile such as Dyneema. As illustrated in Fig. 3B, the tension member 7 comprises several straps for interconnecting the rim plate 5 and the base plate 4. Furthermore, in the embodiment illustrated in figures 3A and 3B, the rim plate 5 is arranged essentially equidistally above the base plate 4 along the entire longitudinal direction LO of the shoe 1. The strap has a zig-zag-profile, striking a beneficial balance between efficient force transmission and low weight.

[0085] Figure 4 shows a further embodiment of the shoe disclosed herein from a side view. In the embodiment shown in Fig. 4, the rim plate 5 is also interconnected to a base plate 4 through a tension member 7, which in the illustrated embodiment, is also made of a strap-shaped tensile-resistant textile material. In the embodiment illustrated in figure 1 , the rim plate 5 and the base plate 4 are integrally formed. The integrally formed plate comprises a single plate in the heel area, which extends to the midfoot area MA, where the plate bifurcates into an upper plate forming the rim plate 5 and a lower plate forming the base plate 4. The base plate 4 and the rim plate 5 are interconnected to each other through the tension member 7 only in the midfoot area MA and in the forefoot area FA.

[0086] Figure 5 shows a further embodiment of the shoe disclosed herein from a rear view (Fig. 5A) and a side view (Fig. 5B). The shoe also comprises a rim plate 5, which in the illustrated embodiment is interconnected to a base element 4 through a tension member 7. In the embodiment illustrated in figure 5, the base element 4 is not made of a rigid material, but instead corresponds to a portion of the shoe that is configured for contacting the bottom of the foot of the wearer. For example, the base element 4 could made of a textile or fabric. As an example, the base element 4 and the tension member 7 could be made of the same textile of fabric, e.g. they could be integrally formed.

[0087] Figure 6 shows a further embodiment of the shoe disclosed herein, in which the rim plate and the base element have a distance between each other that varies along the longitudinal direction of the shoe. Specifically, Fig. 6A shows the shoe of this embodiment and Fig. 6B shows the rim plate and the base element of this shoe, which are integrally formed in this embodiment. The base plate 4 of the embodiment illustrated in figure 6 and the rim plate 5 of this embodiment are interconnected to each other through a tension member 7, which in this embodiment comprises textile straps, e.g. arranged in a zig-zag fashion. The base plate 4 and the rime plate 5 are interspaced from each other in the vertical direction in the forefoot area FA and in the heel area HA. By contrast, in the midfoot area MA, the rim plate 5 and the base plate 4 approach each other and eventually contact each other, as illustrated in Figs. 6A and 6B. Furthermore, Fig. 6B also illustrates that the rim plate 5 is arranged circumferentially around the entire upper 2 (upper not shown in Fig. 6B). More specifically, as illustrated in Fig. 6B, the rim plate 5 comprises a forefoot segment 54, a heel segment 53, a medial segment 52 and a lateral segment 51.
